Singapore’s accounting sector is one of the most competitive in Asia, and for good reason. The city-state’s regulatory framework, from ACRA compliance and IRAS tax obligations to the Companies Act requirements, demands that businesses work with accountants who know the local landscape inside out. Getting this wrong carries real consequences: penalties, missed deadlines, and financial reporting that doesn’t hold up under scrutiny.
This guide covers 20 of the best accounting firms operating in Singapore in 2026. Our selection draws on verified client ratings, the breadth of services offered, firm reputation, and the types of clients each firm is best positioned to serve. We’ve included firms across a range of sizes, from boutique specialists to mid-tier and multinational practices, so whether you’re a sole trader, an SME, or a regional operation, there’s a fit here for you.
Ratings and reviews referenced throughout are sourced from Google Business Profile listings. Where a firm carries a high volume of reviews alongside a strong score, that’s generally a reliable signal of consistent delivery, not just a few satisfied clients. Where ratings are unavailable, we’ve assessed firms on their track record, service range, and standing within the profession.
1. AG Singapore
Five-star rated accountancy firm with 259 verified client reviews
AG Singapore holds a perfect 5.0-star rating across 259 client reviews, which puts it in rare company for an accounting firm of any size. That volume of positive feedback suggests consistent delivery across a wide client base rather than a handful of glowing one-offs. The firm handles a full range of accounting, tax, and corporate compliance services for Singapore businesses.
The firm positions itself as accessible and responsive, which tends to matter most to small and mid-sized businesses that need timely answers rather than waiting days for a callback. AG Singapore’s reviews frequently mention clear communication and a team that explains obligations in plain terms rather than burying clients in jargon.
For businesses new to Singapore’s regulatory requirements, or those frustrated with impersonal service from larger firms, AG Singapore represents a strong starting point. The combination of a proven track record and a high review count gives prospective clients more data to work with than most firms on this list.
Pros
- Perfect 5.0-star rating across 259 reviews, one of the highest review volumes on this list
- Strong reputation for clear communication and responsiveness
- Full range of accounting, tax, and compliance services
- Well-suited to businesses that want a firm they can actually reach
Cons
- Website and service depth harder to assess without a direct consultation
- May not suit very large or complex multinational structures
Best for: SMEs and growing businesses in Singapore that want a proven, responsive firm with a strong client satisfaction record.

2. Harvest Accounting Pte. Ltd.
Singapore accounting firm built on direct contact and five-star client feedback
Harvest Accounting carries a 5.0-star rating and has built its reputation on a direct, personal approach to client service. In a sector where businesses often feel they’re passed between junior staff, Harvest’s model of keeping clients connected to senior professionals is a meaningful differentiator.
The firm covers accounting, tax, and corporate compliance for Singapore-based businesses. Its service offering is well-suited to SMEs and owner-operated businesses that want their accountant to understand their specific situation rather than treat them as one of hundreds of identical files.
Clients who’ve reviewed the firm consistently highlight accessibility and quality of advice as standout qualities. For a business owner who’s had poor experiences with impersonal or slow-moving accounting firms, Harvest’s approach is worth a closer look.
Pros
- 5.0-star rating with a reputation for direct, personal service
- Senior-level contact rather than being handed off to junior staff
- Good fit for owner-managed businesses with specific needs
- Covers accounting, tax, and compliance comprehensively
Cons
- Smaller firm may have capacity limitations during peak filing periods
- May not offer the full advisory depth of larger mid-tier firms
Best for: Owner-operated businesses and SMEs that value direct access to senior professionals and personalised service.

3. Precursor Assurance LLP
Chartered accountants covering audit, tax, and compliance for Singapore businesses
Precursor Assurance LLP is a chartered accountancy firm with a 4.7-star rating, offering audit, tax, and compliance services to businesses operating in Singapore. The firm’s structure as a limited liability partnership signals a level of professional commitment and regulatory standing that clients in audit-heavy industries will appreciate.
The firm’s audit capability is a key strength. Many smaller accounting outfits can handle bookkeeping and tax returns but lack the accreditation and experience to conduct statutory audits. Precursor bridges that gap for businesses that need a single firm to manage the full compliance picture.
Client feedback points to a firm that takes its obligations seriously and communicates well through the audit and compliance process. For businesses approaching their first statutory audit or looking to consolidate services under one roof, Precursor is a credible option.
Pros
- Chartered accountants with audit, tax, and compliance capability under one roof
- 4.7-star rating reflects consistent client satisfaction
- LLP structure adds professional accountability
- Good option for businesses needing statutory audit services
Cons
- Rating slightly below the top-tier firms on this list
- Smaller practice may face resource constraints on large or complex engagements
Best for: Singapore businesses requiring statutory audit alongside tax and compliance support from a chartered accountancy practice.
Website: precursor.com.sg
4. Timcole
Accounting firm with a 4.9-star rating serving Singapore businesses across multiple service areas
Timcole holds a 4.9-star rating, placing it among the highest-rated accounting firms on this list. The firm serves Singapore businesses across accounting, tax, corporate secretarial, and payroll services, making it a practical choice for businesses looking to consolidate administrative and compliance functions with a single provider.
The firm has a visible online presence and a clear service structure, which helps prospective clients understand what they’re engaging before the first conversation. This transparency in how services are packaged and priced is something not all accounting firms manage well.
Timcole’s review base reflects strong client satisfaction across different business types, from startups to established SMEs. The firm’s ability to handle company incorporation alongside ongoing accounting work also makes it useful for businesses setting up in Singapore for the first time.
Pros
- 4.9-star rating with broad service coverage including payroll and corporate secretarial
- Clear online presence and transparent service structure
- Useful for incorporation and ongoing compliance in one place
- Suits both startups and established SMEs
Cons
- May not have the depth for complex multinational or listed company work
- Service breadth can sometimes mean less specialist depth in specific areas
Best for: Startups and SMEs in Singapore looking for a high-rated firm to handle accounting, tax, payroll, and corporate secretarial work.

5. Kreston Helmi Talib
Mid-market accounting firm handling audit, tax, and advisory for Singapore businesses
Kreston Helmi Talib is part of the Kreston International network, a global association of independent accounting firms. That affiliation gives the firm access to international expertise while maintaining a local team focused on Singapore’s regulatory environment. The firm handles audit, tax, and advisory work for mid-market businesses and owner-managed enterprises.
Its 3.7-star rating is the lowest on this list, which is worth noting. That said, Google ratings for professional services firms can be influenced by a relatively small number of reviews, and the firm’s long-standing presence in Singapore and its Kreston network membership speak to institutional credibility that a star rating alone doesn’t fully capture.
For businesses that need a firm with international reach and mid-market positioning, Kreston Helmi Talib offers something that smaller boutique practices can’t: the ability to coordinate across jurisdictions through a recognised global network.
Pros
- Member of Kreston International global accounting network
- Capable of cross-border and multi-jurisdiction work
- Mid-market focus suits businesses beyond the startup stage
- Full audit, tax, and advisory capability
Cons
- 3.7-star rating is the lowest on this list
- May feel less personal than smaller boutique firms
- Better suited to established businesses than early-stage companies
Best for: Mid-market Singapore businesses and owner-managed enterprises that need audit and tax expertise with international network access.
Website: krestonhelmitalib.com.sg
6. PKF-CAP LLP
Full-service accounting firm with a global network and a focus on owner-managed businesses
PKF-CAP LLP is the Singapore member firm of PKF International, one of the larger global accounting networks. The firm offers audit, tax, advisory, and corporate services to Singapore businesses and owner-managed enterprises, with the backing of a well-recognised international brand.
The firm carries a 5.0-star rating, which is impressive given its size and the complexity of the engagements it typically handles. PKF-CAP’s international affiliation means it can support businesses with cross-border structures, regional expansion, or foreign investor requirements, areas where purely local firms may have limitations.
For owner-managed businesses that have outgrown smaller accounting practices but aren’t ready for the fees associated with Big Four firms, PKF-CAP sits in a useful middle ground. The combination of network resources and a Singapore-focused team gives clients access to genuine depth without the overhead of the largest firms.
Pros
- 5.0-star rating with PKF International network backing
- Strong for owner-managed businesses with international requirements
- Full-service capability across audit, tax, and advisory
- Useful middle-ground between boutique and Big Four
Cons
- Network affiliation may come with higher fee expectations
- Very small startups may find the firm’s focus skews toward more established businesses
Best for: Owner-managed enterprises and mid-sized Singapore businesses that need full-service accounting with international network support.

7. Margin Wheeler
Company incorporation and accounting services for Singapore businesses, rated 4.9 stars
Margin Wheeler specialises in company incorporation alongside ongoing accounting and compliance services, making it particularly well-suited to businesses entering the Singapore market for the first time. With a 4.9-star client rating, the firm has built a strong reputation among founders and business owners navigating the setup process.
The firm’s dual focus on incorporation and accounting means clients can move from company registration to ongoing compliance without switching providers midway. That continuity is genuinely valuable, as it reduces the risk of information falling through the gaps during a critical early phase of business operations.
Margin Wheeler’s client reviews highlight practical guidance and clear communication during what can be a confusing period for new entrants to Singapore. For foreign-owned businesses or entrepreneurs setting up their first Singapore entity, the firm’s experience in this specific area is a meaningful advantage.
Pros
- 4.9-star rating with specific strength in company incorporation
- Covers both setup and ongoing accounting in one engagement
- Practical guidance valued by first-time Singapore entrants
- Useful for foreign-owned businesses and entrepreneurs
Cons
- Incorporation-focused positioning may mean less depth in complex audit work
- Better suited to newer businesses than large established enterprises
Best for: Entrepreneurs and foreign businesses setting up in Singapore who want incorporation and accounting handled by the same firm.
Website: marginwheeler.com
8. KJ Advisory Pte Ltd
Specialist tax and corporate advisory for Singapore businesses and expatriates
KJ Advisory holds a 5.0-star rating and focuses specifically on tax and corporate advisory work for Singapore businesses and expatriates. That specialisation matters: tax advice is an area where generalist accounting firms often fall short, and businesses or individuals with more complex tax positions benefit from working with a firm that treats tax as a primary discipline rather than a side offering.
The firm’s focus on expatriates is a useful differentiator in Singapore’s market. Foreign professionals and business owners often face cross-border tax complexity that local-only firms aren’t equipped to address. KJ Advisory’s positioning in this space suggests a team that understands both Singapore tax law and how it interacts with foreign tax obligations.
For businesses or individuals dealing with transfer pricing, personal tax planning, GST registration, or corporate restructuring, KJ Advisory’s advisory-led model is more likely to produce useful outcomes than a standard compliance-focused accounting firm.
Pros
- 5.0-star rating with specialist tax and advisory focus
- Specific expertise serving expatriates and foreign-owned businesses
- Advisory-led approach suited to complex or non-standard tax situations
- Good option for cross-border tax planning and corporate restructuring
Cons
- Narrower scope than full-service accounting firms
- May not be the right fit for businesses wanting a single provider for audit and bookkeeping
Best for: Singapore businesses and expatriates with complex tax or corporate advisory requirements who need specialist guidance beyond standard compliance.
Website: kjadvisorygroup.com
9. 3E Accounting Pte Ltd
CPA-led accounting firm covering tax, audit, and compliance for Singapore businesses
3E Accounting is a well-known name in Singapore’s SME accounting space, with a 4.7-star rating and a broad service offering that spans tax, audit, company incorporation, and corporate compliance. The firm has built significant visibility through its online presence, which makes it easier for prospective clients to research services and fee structures before making contact.
As a CPA-led firm, 3E Accounting brings certified professional accounting standards to its work, which matters for businesses that need their financials to hold up in front of investors, banks, or regulators. The firm serves a wide range of business types, from newly incorporated companies to more established SMEs.
The firm’s scale and reputation mean it has experience across many industry sectors, which can be useful for businesses in less common categories. Reviews note efficient processing and a structured approach to compliance deadlines, which suits businesses that prioritise reliability over white-glove service.
Pros
- 4.7-star rating with strong online visibility and transparent service descriptions
- CPA-led practice with audit capability
- Broad experience across industry sectors and business types
- Efficient, structured approach to compliance deadlines
Cons
- Larger client base may mean less personalised attention for smaller accounts
- Some reviews suggest variability in service quality across different team members
Best for: SMEs and newly incorporated Singapore businesses looking for a structured, CPA-certified firm with full compliance and audit capability.
Website: 3ecpa.com.sg
10. Tan, Chan and Partners Accounting Firm
Singapore CPA firm handling tax, audit, and corporate compliance for established businesses
Tan, Chan and Partners holds a 5.0-star rating and brings a CPA-accredited practice to the full spectrum of tax, audit, and corporate compliance work. The firm’s positioning toward established businesses suggests a team experienced in dealing with more complex compliance structures than a typical startup-focused outfit handles.
The partnership model at firms like this often means clients benefit from working with principals who have significant accumulated experience. For businesses with intricate corporate structures, multiple related entities, or unusual tax positions, that depth of experience can make a material difference to the quality of advice received.
Client reviews reflect a firm that takes its professional obligations seriously and maintains clear communication throughout the engagement. For companies that have grown beyond the reach of smaller bookkeeping-style practices, Tan, Chan and Partners is worth considering.
Pros
- 5.0-star rating with CPA accreditation
- Partnership model brings senior-level experience to client work
- Strong for established businesses with complex compliance needs
- Full audit, tax, and corporate compliance coverage
Cons
- Positioning toward established businesses may mean less flexibility for early-stage companies
- Partnership structure can sometimes mean slower turnaround during peak periods
Best for: Established Singapore companies with complex compliance, audit, and tax requirements that need a CPA-accredited partnership.
Website: tanchan-cpa.com
11. Metropolitan Management Services Pte. Ltd. (MetroCorp)
Established accountancy firm covering audit, tax, and corporate compliance for Singapore businesses
MetroCorp carries a 4.9-star rating and has operated in Singapore long enough to have built a reputation that extends beyond online reviews. The firm handles audit, tax, and corporate compliance for Singapore businesses, with a track record that spans different economic cycles and regulatory changes.
Longevity in Singapore’s accounting sector isn’t trivial. The regulatory environment evolves regularly, and firms that have navigated multiple rounds of IRAS updates, Companies Act amendments, and reporting standard changes bring a depth of institutional knowledge that newer entrants can’t replicate quickly.
MetroCorp’s client feedback reflects consistent delivery and a team that handles compliance without creating unnecessary complexity for clients. For businesses that want an established, dependable firm rather than the newest player in the market, MetroCorp is a solid choice.
Pros
- 4.9-star rating with an established track record in Singapore
- Institutional knowledge across multiple regulatory cycles
- Reliable delivery on audit, tax, and compliance
- Good fit for businesses that value stability over novelty
Cons
- Established firms can sometimes be slower to adopt new technology or service models
- May not be the most agile option for fast-moving startups
Best for: Singapore businesses that want an established, reliable firm with a long track record in audit, tax, and corporate compliance.
Website: metrocorp.com.sg
12. UHY Lee Seng Chan and Co
Mid-tier audit and accounting firm serving Singapore businesses and international groups
UHY Lee Seng Chan and Co is the Singapore member firm of UHY International, a global network of independent accounting and business advisory firms. With a 5.0-star rating, the firm serves Singapore businesses and international groups that need mid-tier accounting expertise with cross-border reach.
The UHY network is particularly useful for businesses with regional or international structures. Member firms share technical resources and can coordinate across jurisdictions, which is a real advantage for groups that operate across Southeast Asia or further afield. For a Singapore-headquartered business with subsidiaries in Malaysia, Indonesia, or further afield, having an accountant connected to a coordinated global network reduces the friction of managing multiple local relationships.
The firm’s combination of network resources and a 5.0-star rating positions it as a strong option for international groups and Singapore companies with cross-border ambitions.
Pros
- 5.0-star rating with UHY International network membership
- Strong for businesses with regional or international structures
- Mid-tier positioning between boutique firms and the Big Four
- Audit and advisory capability for complex multi-entity groups
Cons
- Network membership may not benefit businesses that operate only in Singapore
- Pricing may reflect international firm overhead
Best for: Singapore-headquartered businesses and international groups needing mid-tier audit and accounting with cross-border coordination capability.
Website: uhylsc.com.sg
13. OneStop Professional Services
Chartered accountant firm with consistent five-star feedback across tax, audit, and business advisory
OneStop Professional Services holds a 5.0-star rating and covers tax, audit, and business advisory for Singapore businesses. The “OneStop” positioning reflects a genuine attempt to consolidate the range of professional services that businesses need, reducing the time spent managing multiple provider relationships.
The firm’s chartered accountant credentials give clients confidence that professional standards are maintained across audit and assurance work. In Singapore, the distinction between certified public accountants and non-accredited bookkeeping services matters particularly for statutory audit requirements and for businesses preparing financials for external stakeholders.
Client reviews are consistently positive, with feedback pointing to a firm that goes beyond pure compliance to offer practical business advice. For SMEs that want more than a firm to file their returns, OneStop’s advisory capability is a genuine plus.
Pros
- 5.0-star rating with chartered accountant credentials
- Covers tax, audit, and business advisory under one roof
- Useful for businesses wanting to consolidate professional service providers
- Advisory approach adds value beyond standard compliance
Cons
- Less brand recognition than network-affiliated firms
- Service breadth may mean less specialist depth in highly technical areas
Best for: Singapore SMEs that want a full-service chartered accountant covering tax, audit, and business advisory without managing multiple providers.
Website: onestop-ca.com
14. Accounting Consultancy Pte. Ltd.
Straightforward accounting and tax services for Singapore businesses and individuals
Accounting Consultancy Pte. Ltd. carries a 4.8-star rating and serves both Singapore businesses and individual clients with accounting and tax services. The firm’s name reflects its positioning: a practical, no-frills approach to the accounting and tax work that businesses and individuals need to stay compliant.
For individuals with personal tax obligations, including those with business income, rental income, or foreign-sourced income, working with a firm that handles both individual and corporate tax is efficient. It avoids the duplication of explaining your full financial picture to two separate providers.
Client feedback points to a firm that handles work thoroughly and communicates clearly about deadlines and obligations. For businesses and individuals looking for dependable accounting support without the overhead of a large practice, Accounting Consultancy is a practical choice.
Pros
- 4.8-star rating with services spanning both individual and corporate clients
- Straightforward approach suited to businesses that want reliable compliance without complexity
- Good option for individuals with tax obligations alongside business filings
- Clear communication noted in client reviews
Cons
- Positioned as a practical compliance provider rather than a strategic advisory firm
- May not suit businesses that need specialist audit or cross-border advisory
Best for: Singapore businesses and individuals looking for dependable, no-fuss accounting and tax services from a well-rated firm.
Website: accountingconsultancy.com
15. Lo Hock Ling and Co.
Established Singapore accounting firm offering tax, audit, and business advisory
Lo Hock Ling and Co. is a long-standing Singapore accounting practice covering tax, audit, and business advisory services. The firm doesn’t have a publicly available Google rating, which limits direct comparison with other firms on this list, but its established presence in the Singapore market is a meaningful indicator of sustained client relationships.
Firms that have operated in Singapore’s competitive accounting market for extended periods typically do so because they deliver consistently for their clients. The absence of a visible review score isn’t necessarily a red flag; many traditional firms in professional services have clientele that simply don’t leave online reviews.
For businesses that value referrals and word-of-mouth reputation over online ratings, Lo Hock Ling and Co. is worth contacting directly. A direct conversation will give a clearer sense of whether the firm’s experience aligns with your specific requirements.
Pros
- Established firm with a long track record in Singapore
- Covers tax, audit, and business advisory
- Sustained market presence suggests consistent client retention
- Worth considering for businesses that rely on professional referrals
Cons
- No publicly available rating to benchmark against other firms
- Online presence is less visible than more digitally active competitors
Best for: Businesses looking for an established, traditional accounting firm in Singapore with broad service coverage and a long operating history.
Website: lohocklingco.com.sg
16. WLP Accounting
Established accounting firm rated 4.8 stars across more than 100 client reviews
WLP Accounting holds a 4.8-star rating across more than 100 client reviews, which represents one of the more substantial review bases among the firms on this list. Consistent performance across that volume of client interactions suggests a firm with reliable processes and quality control, not just occasional excellent outcomes.
The firm serves Singapore businesses across accounting, tax, corporate secretarial, and payroll. That range of services positions WLP as a practical option for businesses wanting to manage multiple administrative functions through a single provider, reducing coordination effort and keeping relevant records in one place.
WLP’s review volume also provides prospective clients with a useful resource: a large body of feedback covering different service types, business sizes, and client situations. Reading through those reviews gives a more complete picture of the firm’s strengths than a single star rating conveys.
Pros
- 4.8-star rating across 100-plus reviews, one of the larger review bases on this list
- Multi-service coverage including payroll and corporate secretarial
- Strong review volume provides a reliable indicator of consistent delivery
- Good fit for businesses wanting consolidated administrative support
Cons
- Broader service scope can sometimes come with less specialist depth
- May not be the best fit for highly complex audit or international tax work
Best for: Singapore businesses that want a well-reviewed, multi-service accounting firm to handle accounting, tax, payroll, and corporate secretarial work.
Website: wlp.com.sg
17. Koh and Lim Audit PAC
Singapore audit firm within the GTO Audit network, covering statutory and corporate compliance
Koh and Lim Audit PAC is a Singapore audit firm backed by the GTO Audit network, with a 5.0-star rating. The firm’s primary focus is audit work, covering statutory audit and corporate compliance requirements for Singapore companies. That specialist focus is worth noting: audit is a regulated activity in Singapore, and firms that concentrate on it tend to develop deeper capability in this area than generalist practices.
Statutory audit is a mandatory requirement for many Singapore companies under the Companies Act, and the quality of an audit firm directly affects how those financial statements are received by ACRA, banks, investors, and other stakeholders. Working with a firm that takes audit as its central discipline rather than an add-on service matters.
The GTO Audit network affiliation provides an additional layer of quality oversight and professional standards. For Singapore businesses approaching their first statutory audit, or those looking to switch audit firms, Koh and Lim is a credible, specialist option.
Pros
- 5.0-star rating with specialist audit focus
- GTO Audit network affiliation adds professional oversight
- Strong for statutory audit and corporate compliance requirements
- Audit-first positioning delivers more depth than generalist firms
Cons
- Narrow audit focus means you’ll need separate providers for bookkeeping and tax if required
- Not suited to businesses looking for a full-service accounting firm
Best for: Singapore companies requiring specialist statutory audit and corporate compliance from a dedicated audit practice.
Website: kohlimaudit.sg
18. Piloto Asia
Company registration and compliance support for businesses setting up or operating in Singapore
Piloto Asia carries a 4.8-star rating and focuses on company registration and compliance for businesses entering or operating in Singapore. The firm is particularly useful for foreign businesses and entrepreneurs who need a guided path through Singapore’s incorporation process, including registered address services, nominee director arrangements, and ongoing compliance obligations.
The firm’s specialisation in the setup and early compliance phase of business operations fills a specific gap. Many accounting firms handle ongoing work well but don’t have the experience or process depth for the nuances of incorporating foreign-owned entities in Singapore. Piloto Asia has clearly built its service model around this specific challenge.
Client reviews highlight practical guidance and responsiveness during the incorporation phase, which is typically when businesses have the most questions and the least familiarity with local requirements. For any business setting up a new Singapore entity, Piloto Asia is worth considering alongside a full-service accounting firm for ongoing work.
Pros
- 4.8-star rating with specialist company registration focus
- Practical guidance for foreign businesses entering Singapore
- Experience with nominee directors, registered address, and compliance obligations
- Responsive during the incorporation phase when questions are most frequent
Cons
- Incorporation-focused; ongoing accounting and audit depth may be more limited
- Businesses past the setup phase may need to transition to a more full-service provider
Best for: Foreign businesses and entrepreneurs registering a new company in Singapore who need specialist guidance through the incorporation and early compliance process.
Website: pilotoasia.com
19. IAN and SON LLP
Established accountancy firm known for personal service and strong client satisfaction
IAN and SON LLP holds a 4.8-star rating and has built its reputation on a personal, relationship-focused approach to accountancy. The LLP structure reflects professional standing, and the firm’s name itself suggests a family or founder-led practice where long-term client relationships are valued over transactional volume.
That kind of firm culture tends to produce better outcomes for clients who want an accountant that learns their business over time rather than treating each engagement as isolated. For small and mid-sized businesses where the owner is deeply involved in financial decisions, having an accountant with genuine familiarity with the business context makes a real difference.
Client feedback consistently points to a firm that listens, responds promptly, and handles work with care. For businesses tired of impersonal service from larger practices, IAN and SON LLP offers a clear alternative.
Pros
- 4.8-star rating with a personal service approach
- LLP structure with professional accountability
- Relationship-focused model suited to long-term client engagements
- Responsive and attentive based on client feedback
Cons
- Smaller firm footprint may limit capacity for very large or complex engagements
- Less visible online presence than some competitors
Best for: Small and mid-sized Singapore businesses that want a personal, relationship-driven accountancy firm with consistent client satisfaction.

20. Grant Thornton Singapore
Multinational accounting firm offering audit, tax, and advisory across Singapore and the region
Grant Thornton is one of the world’s largest accounting networks, and its Singapore practice delivers audit, tax, and advisory services across a wide range of industries and business sizes. With a 4.0-star rating, the Singapore office sits below the top-tier scores on this list, but the firm’s global standing and depth of resources are unmatched at this scale outside the Big Four.
For publicly listed companies, large privately held businesses, or multinationals requiring assurance and advisory work that holds up to international scrutiny, Grant Thornton Singapore offers a level of technical depth and brand recognition that smaller local firms simply can’t replicate. The firm’s sector specialists cover areas including financial services, manufacturing, and technology, which is useful for businesses in regulated or complex industries.
The 4.0-star rating is worth contextualising: large multinational firms often receive more mixed reviews than boutique practices because they serve a broader and more varied client base, and client expectations are sometimes set against the full weight of the global brand rather than the local team. A direct conversation with the relevant Singapore team will give a more accurate read than the aggregate score alone.
Pros
- Global Grant Thornton network with deep technical resources and sector specialists
- Suitable for listed companies, large enterprises, and multinational groups
- Full audit, tax, and advisory capability with international credibility
- Industry-specific expertise in financial services, manufacturing, and technology
Cons
- 4.0-star rating is the second lowest on this list
- Large firm scale can mean less personalised service for mid-sized clients
- Fee levels reflect a large international firm and may be higher than local alternatives
Best for: Listed companies, large enterprises, and multinational groups in Singapore requiring internationally credible audit, tax, and advisory services.

Who is the best accountants in Singapore?
Based on client ratings and review volumes, AG Singapore leads this list with a perfect 5.0-star score across 259 verified reviews, making it the most comprehensively validated option for general business accounting. PKF-CAP LLP, UHY Lee Seng Chan and Co, KJ Advisory, and Harvest Accounting also hold 5.0-star ratings. The right answer for your business depends on your size, industry, and what you need an accountant to do. A startup registering its first entity has different requirements from a mid-market group looking for statutory audit with regional coordination. Use the “Best for” labels throughout this guide to identify which firms match your situation most closely.
How much does a accountant cost in Singapore?
Accounting fees in Singapore vary significantly depending on the scope of work, the firm’s size, and your business complexity. For basic bookkeeping and annual tax filing, small businesses can expect to pay anywhere from SGD 100 to SGD 500 per month for ongoing services, or a one-off fee for annual compliance work. Statutory audit fees for smaller companies typically start from SGD 3,000 to SGD 8,000 per year and rise considerably for larger or more complex entities. Incorporation services are often priced as a fixed package, typically between SGD 500 and SGD 2,000 depending on what’s included. Advisory and tax planning work is usually priced by the hour or by engagement scope. The best approach is to request quotes from two or three firms with experience in your specific business type and compare what’s included.
How do I choose a accountant in Singapore?
Start by identifying what you actually need. If you’re a new company, prioritise firms with incorporation and early-stage compliance experience. If you have an established business, focus on audit credentials and tax advisory depth. Check whether the firm is a registered public accountant or a chartered accountant, as these credentials are required for statutory audit work in Singapore. Look at client reviews for firms you’re considering, paying attention to the volume of reviews as well as the score. A firm with 200 reviews at 4.9 stars gives you more data than one with five reviews at 5.0. Finally, book an initial consultation: how quickly they respond, how clearly they explain your obligations, and whether they ask the right questions about your business are all signals of the service quality you’ll receive as a client.
What should I look for in a accountant?
In Singapore specifically, check that the accountant or firm holds the appropriate professional certifications for the work you need, including ICPAS membership or CPA status for audit engagements. Beyond credentials, look for a firm that communicates clearly and proactively, not one that only surfaces when a deadline is imminent. Responsiveness matters: your accountant should be reachable when IRAS queries arise or when you need to make a financial decision quickly. Ask whether you’ll have a dedicated point of contact or whether your file will move between staff. Understand how the firm handles ACRA filings, IRAS submissions, and GST reporting, and whether those are included in the quoted fee or billed separately. A good accountant should also be willing to explain your obligations and financial position in plain language, not just deliver reports without context.
Are there good accountants for small businesses in Singapore?
Yes, and several firms on this list are specifically well-suited to small businesses. AG Singapore, Harvest Accounting, Timcole, and WLP Accounting all have strong ratings and service structures built around the needs of SMEs and smaller operations. For businesses just starting out, Margin Wheeler and Piloto Asia offer incorporation alongside early-stage accounting support. The key for small businesses is to find a firm where you’re not the smallest client in the room: boutique and mid-sized practices tend to give smaller accounts more attention than large firms where SME work can get deprioritised. Fixed-fee packages, which several firms on this list offer, are also worth seeking out as they make budgeting simpler and remove the anxiety of watching the clock during every phone call.
Finding the right accounting firm in Singapore is worth the research time upfront. The firms on this list cover the full range of business needs, from company incorporation and basic compliance through to statutory audit and cross-border advisory. Use the client ratings, service descriptions, and “Best for” guidance in this guide as a starting point, then speak directly to two or three shortlisted firms to confirm they understand your business and can deliver what you need. A good accountant isn’t just a compliance cost. They’re one of the more consequential professional relationships a Singapore business owner maintains.
