Singapore’s tax environment is relatively straightforward compared to many other jurisdictions, but that simplicity can be deceptive. Corporate income tax filings, GST registration and returns, withholding tax obligations, and personal assessments for expatriates all carry their own compliance requirements. Getting any of them wrong can attract penalties from the Inland Revenue Authority of Singapore (IRAS), which is why businesses and individuals operating in Singapore routinely engage professional tax accountants rather than managing obligations in-house.
The firms listed here were selected based on verified client ratings, the breadth of services offered, specialisation (particularly for cross-border and expatriate tax situations), and their demonstrated track record with Singapore-registered entities. Where ratings are available, they reflect aggregated client feedback from Google and other platforms at the time of compilation. The list covers firms serving sole traders, SMEs, multinational subsidiaries, and expatriates from Australia, the United States, and other countries with specific offshore tax obligations.
Whether you are incorporating a new company, managing ongoing compliance, or dealing with a cross-border tax situation, the firms below represent the strongest options available in Singapore in 2026.
1. Odin Tax – Australian Tax Returns for Aussie Expats
Australian tax specialists serving expats based in Singapore
Odin Tax focuses specifically on Australian tax returns for Australians living abroad, with Singapore being one of their primary service markets. For Australians on employment passes or entrepreneur visas in Singapore, Australian tax obligations do not simply disappear, and the residency rules around tax liability are frequently misunderstood. Odin Tax handles this complexity directly, assessing residency status, foreign income exemptions, and the interaction between Australian and Singapore tax rules.
The firm holds a 4.9/5 rating, with clients consistently noting the clarity of communication and the firm’s ability to explain Australian tax concepts to people who have been out of the country for years. This is a niche that most Singapore-based accounting firms do not adequately cover, and Odin Tax fills it with a service built entirely around expat circumstances rather than adapted from a domestic Australian model.
Services include individual tax return preparation, residency assessments, capital gains tax advice on Australian property held while living abroad, and ongoing advisory for Australians who are uncertain about their obligations while working in Singapore or elsewhere in the region.
Pros
- Dedicated focus on Australian expat tax, not a general accounting firm with an expat add-on
- Strong understanding of the ATO’s approach to overseas residents
- 4.9/5 client rating reflecting consistent service quality
- Well-suited to Australians with Australian property, investments, or superannuation while living in Singapore
Cons
- Not a Singapore corporate tax provider, so businesses needing local compliance support will need a separate firm
- Scope is limited to Australian tax matters only
Best for: Australians living and working in Singapore who need to meet their Australian tax return obligations

2. AG Singapore
Tax accounting and compliance advisory for Singapore-based businesses
AG Singapore is a tax accounting firm serving Singapore businesses with a mix of compliance and advisory work. The firm holds a 5.0/5 rating, which reflects a client base that is clearly well-served. Their work covers corporate tax filing, GST compliance, and advisory support for businesses that need guidance beyond simple return preparation.
The firm’s approach appears to suit owner-operated businesses and SMEs that want a consistent point of contact rather than a rotating team of accountants. Clients who leave reviews frequently mention the responsiveness of the team and the quality of advice received during audits or when dealing with IRAS queries.
For Singapore-registered companies that need a reliable accounting partner for annual compliance as well as more substantive tax planning, AG Singapore is a firm worth contacting early in the engagement process rather than waiting until filing deadlines approach.
Pros
- 5.0/5 client rating across verified reviews
- Handles both compliance filing and tax advisory in one firm
- Responsive communication noted consistently by clients
- Suitable for SMEs and owner-operated businesses
Cons
- Less prominent for expatriate personal tax work
- Limited public information about team size or specialist capabilities
Best for: Singapore SMEs and owner-operated businesses needing combined compliance and advisory tax services

3. Hayden T Joseph CPA LLP (Advanced American Tax Pte Ltd)
US tax specialist for American expats and cross-border earners in Singapore
Hayden T Joseph CPA LLP, operating as Advanced American Tax Pte Ltd in Singapore, is the standout option for US citizens and green card holders living in Singapore who must continue filing US federal tax returns regardless of where they earn their income. The United States taxes its citizens on worldwide income, which creates filing obligations that most Singapore-based accountants are not equipped to manage. This firm is specifically built around that requirement.
The firm holds a 5.0/5 rating and serves Americans working across a wide range of industries in Singapore, from finance to technology to regional management roles. Services include FBAR (Foreign Bank Account Report) filings, Form 1040 preparation, foreign earned income exclusion claims, and treaty analysis between the US and Singapore. For Americans with business interests across both jurisdictions, the cross-border complexity can be significant, and Hayden T Joseph’s team handles it with deep familiarity.
The firm also advises on exit tax considerations, citizenship renunciation, and the tax implications of holding Singapore permanent residency while maintaining US citizenship. These are niche areas where errors carry serious financial and legal consequences, and the firm’s specialisation here sets it apart from generalist providers.
Pros
- Dedicated US expat tax specialists, not a general firm with a US tax add-on
- 5.0/5 client rating
- Covers FBAR, FATCA, foreign earned income exclusions, and treaty matters
- Advises on complex scenarios including exit tax and dual residency
Cons
- Focused on US tax compliance, not Singapore corporate or GST matters
- May not be the right fit for non-US clients
Best for: US citizens and green card holders living in Singapore who need to meet their American federal tax obligations

4. Koh Management
Affordable corporate secretarial and GST bookkeeping for Singapore companies
Koh Management positions itself as an affordable option for Singapore companies that need corporate secretarial services alongside GST registration, bookkeeping, and tax compliance support. The firm holds a 5.0/5 rating and appears to serve a broad range of small businesses and startups that want to keep their accounting costs predictable without sacrificing service quality.
The combination of corporate secretarial and accounting services under one roof is a practical arrangement for newly incorporated companies that need to establish their compliance infrastructure quickly. Koh Management handles the ACRA filing requirements that come with company incorporation, the ongoing secretarial obligations, and the IRAS filings that follow once trading begins.
Client feedback highlights the accessibility of the team and the competitive fee structure. For businesses at the early stage of their Singapore operations who want a single provider managing multiple compliance streams, Koh Management is a practical choice.
Pros
- 5.0/5 rating with consistent positive feedback on affordability
- Combines corporate secretarial and accounting services
- Practical for newly incorporated Singapore companies
- Transparent pricing positioning
Cons
- Better suited to smaller companies than large or complex corporate structures
- Advisory depth may be limited compared to larger specialist tax firms

5. Timcole
Singapore tax accountants handling corporate and personal compliance
Timcole is a Singapore-based accounting firm covering both corporate and personal tax compliance. The firm holds a 4.9/5 rating and handles the full range of obligations that Singapore-registered companies face, including estimated chargeable income (ECI) filings, corporate tax returns, and GST compliance. Personal tax filing services are also available for expatriates and business owners.
The firm appears to work well with companies that have outgrown basic bookkeeping services and need a more structured accounting relationship. Timcole offers packages that bundle compliance services, which suits businesses that want a predictable annual cost for their tax and accounting obligations rather than paying ad hoc fees for each filing.
Client reviews mention the firm’s accuracy, attention to deadlines, and willingness to answer questions throughout the year rather than only at filing time. These are practical qualities that matter considerably when dealing with IRAS requirements.
Pros
- 4.9/5 client rating
- Handles both corporate and personal tax filings
- Packaged pricing available for annual compliance
- Responsive to client questions between filing periods
Cons
- Not a specialist in cross-border or expatriate home country tax obligations

6. J Accounting Pte. Ltd.
Singapore tax compliance firm covering GST, corporate, and individual returns
J Accounting Pte. Ltd. offers tax and accounting services to businesses and individuals in Singapore, with a particular focus on corporate tax returns, GST compliance, and ongoing bookkeeping. The firm holds a 4.9/5 rating and is noted for its methodical approach to compliance work.
The firm serves a range of business sizes, from sole proprietors to private limited companies with more complex filing requirements. GST compliance is handled as part of a broader accounting engagement, which means clients are not managing separate providers for bookkeeping and tax. This integrated approach reduces the risk of inconsistencies between financial records and tax filings.
For businesses that want an affordable firm to take on the full compliance burden without requiring constant direction from the business owner, J Accounting is a practical option with a strong track record reflected in its client ratings.
Pros
- 4.9/5 rating with consistent positive client feedback

7. Margin Wheeler
Company incorporation and tax advisory for Singapore businesses
Margin Wheeler combines company incorporation services with ongoing tax advisory for Singapore businesses. The firm holds a 4.9/5 rating and is particularly active in helping foreign entrepreneurs and regional businesses establish a Singapore entity and then manage the compliance obligations that follow from incorporation.
Tax advisory at Margin Wheeler goes beyond simple return preparation. The firm provides guidance on structuring, profit repatriation, and the tax implications of operating across multiple Asian markets from a Singapore base. For businesses using Singapore as a regional holding or operating hub, this kind of advisory context is more useful than a firm focused purely on compliance filing.
The firm is also noted for its work with startups and early-stage companies navigating the transition from sole proprietor to private limited company structure, a common move in Singapore’s business environment that carries its own tax and compliance implications.
Pros
- 4.9/5 rating
- Advisory capability beyond basic compliance filing
- Useful for businesses using Singapore as a regional hub
- Covers the full journey from incorporation through to ongoing tax management
Cons
- Less focused on individual or expatriate personal tax
- May be more engagement-heavy than businesses needing simple annual filings
Best for: Foreign entrepreneurs and regional businesses incorporating in Singapore and needing advisory alongside compliance

8. Piloto Asia
Company registration and tax accounting for businesses operating across Asia
Piloto Asia serves businesses looking to establish and operate in Singapore and across the broader Asian region. The firm holds a 4.9/5 rating and covers company registration, corporate secretarial services, and tax accounting as part of a package aimed at foreign businesses entering the Singapore market.
The firm’s regional focus is a genuine differentiator. For businesses that are incorporating in Singapore but also have operations in other Asian jurisdictions, Piloto Asia can provide context on how Singapore’s tax framework interacts with regional business structures. This is a practical benefit for companies managing cross-border supply chains, regional payrolls, or multi-entity group structures.
Piloto Asia is frequently mentioned in the context of market entry support, which means the team is experienced in helping clients who are unfamiliar with Singapore’s regulatory environment get their compliance foundations right from the outset.
Pros
- 4.9/5 client rating
- Strong regional context for businesses operating across multiple Asian markets
- Covers registration, secretarial, and tax as an integrated service
- Experienced with foreign businesses entering Singapore
Cons
- May be more than needed for simple single-entity Singapore compliance

9. Fryday
Full-service accounting firm covering incorporation, payroll, tax, and compliance in Singapore
Fryday is a full-service provider covering company incorporation, corporate secretarial services, accounting, payroll, and tax compliance for Singapore businesses. The firm holds a 4.8/5 rating and appears to serve a broad SME client base that values having all administrative and compliance functions managed by a single provider.
The payroll component is a meaningful addition to the service mix. Singapore payroll involves CPF (Central Provident Fund) contributions, IR8A filings, and auto-inclusion submissions to IRAS, all of which need to align with the company’s broader tax position. Having the same firm handle payroll and tax reduces the risk of discrepancies arising between the two.
Fryday’s positioning suits owner-managed businesses that want to minimise the number of external service providers they deal with. The firm handles the administrative overhead that takes time away from core business operations, from incorporation paperwork through to annual compliance cycles.
Pros
- 4.8/5 rating
- Payroll and tax managed together, reducing inconsistency risk
- Single provider for incorporation through to ongoing compliance
- Practical for SMEs wanting reduced administrative overhead
Cons
- Full-service model may include services some businesses do not need, affecting pricing value
- Less suited to businesses with complex or specialist tax advisory requirements
Best for: Owner-managed Singapore SMEs that want one provider to handle incorporation, payroll, accounting, and tax compliance

10. One Tax CM Pte Ltd
Singapore tax accountancy covering compliance, planning, and entity management
One Tax CM Pte Ltd is a Singapore tax accountancy firm handling compliance, tax planning, and entity management for businesses operating in Singapore. The firm holds a 5.0/5 rating, which places it among the highest-rated firms on this list. Their service scope covers corporate income tax, GST, and advisory on structuring matters that affect a company’s tax position over time.
The firm’s focus on tax planning alongside compliance distinguishes it from firms that handle filing work alone. For growing businesses where decisions about dividends, profit retention, director remuneration, and intercompany transactions carry meaningful tax implications, having an accountant who can advise on planning as well as file returns adds practical value.
Client feedback points to the team’s ability to communicate clearly and provide explanations that make tax decisions intelligible to business owners who are not accountants. This is a quality that is easy to underestimate until you have worked with a firm that does not provide it.
Pros
- 5.0/5 client rating
- Tax planning capability alongside compliance filing
- Clear communication noted repeatedly in client reviews
- Covers entity management as well as direct tax obligations
Cons
- Smaller firm profile may mean capacity constraints for very large or complex engagements
- Less visibility on expatriate personal tax services
Best for: Singapore businesses wanting tax planning advice alongside their annual compliance obligations

11. Singapore Tax Accounting
Tax accounting and compliance for individuals and businesses in Singapore
Singapore Tax Accounting provides compliance and advisory services to both individuals and businesses operating in Singapore. The firm covers corporate tax filings, personal income tax, and GST compliance. No aggregated rating was available at the time of compilation, which makes direct comparison with other firms on this list more difficult.
The firm’s website and service positioning suggest a general practice covering the standard range of Singapore tax obligations. For individuals or businesses that prefer a locally focused provider with a clear Singapore specialisation by name and by scope, Singapore Tax Accounting is worth evaluating.
As with any firm where external ratings data is limited, prospective clients should request references or case studies relevant to their own situation before engaging. The absence of a published rating does not reflect negatively on the firm’s quality, but it does mean there is less public evidence to assess.
Pros
- Clear Singapore-focused positioning for both personal and corporate tax
- Covers a broad range of standard compliance needs
- Accessible for individuals as well as businesses
Cons
- No verified rating available to assess client satisfaction
- Less information available publicly to evaluate specialist capabilities
Best for: Individuals and Singapore businesses seeking straightforward tax compliance from a locally focused provider

12. Accounting Consultancy Pte. Ltd.
Tax compliance and advisory services for Singapore businesses
Accounting Consultancy Pte. Ltd. offers compliance and advisory services to Singapore-based businesses, holding a 4.8/5 rating from its client base. The firm handles corporate tax filings, GST, and advisory work for businesses that need guidance beyond standard compliance preparation.
The advisory component is worth noting. Many smaller accounting firms in Singapore limit their work to filing returns and maintaining books. A firm that also engages with clients on planning questions, such as the tax treatment of new revenue streams or the implications of restructuring, provides a more complete service for businesses at a growth stage.
Client reviews for Accounting Consultancy mention professionalism and the quality of advice received during more complex tax situations. This suggests the firm is equipped to handle engagements that go beyond routine annual filings.
Pros
- 4.8/5 client rating
- Advisory capability alongside standard compliance work
- Professional handling of more complex tax situations noted in reviews
- Suitable for businesses at a growth or transition stage
Cons
- Less prominent than some larger firms in the Singapore accounting market
- Limited public information on team size and specialist areas
Best for: Singapore businesses needing compliance and advisory support during periods of growth or structural change

13. One Accounting Services Singapore
Bookkeeping, company registration, and tax filing for Singapore businesses
One Accounting Services Singapore covers company registration, ongoing bookkeeping, and tax filing as a combined service for Singapore businesses. The firm holds a 5.0/5 rating and appears to serve a client base that includes newly incorporated businesses as well as established companies wanting to consolidate their accounting and compliance under one provider.
The combination of registration, bookkeeping, and tax filing in one service relationship reduces the coordination effort for business owners who would otherwise need to manage these separately. For companies that are incorporating and want their compliance infrastructure set up correctly from day one, this integrated model is a practical choice.
The 5.0/5 rating is notable for a general-purpose accounting firm and suggests a high level of client satisfaction with the service delivery. Clients at this kind of firm typically value reliability and accuracy over specialist advisory depth.
Pros
- 5.0/5 client rating
- Covers registration, bookkeeping, and tax filing as a combined service
- Reduces coordination effort for business owners managing multiple compliance needs
- Well-suited to newly incorporated Singapore companies
Cons
- Less suited to businesses needing specialist tax advisory or cross-border planning
- Website is modest in detail, which makes it harder to assess the depth of services available
Best for: Singapore businesses wanting registration, bookkeeping, and annual tax filing handled by a single provider

14. Singapore Corporate Services Pte Ltd
Tax accounting and corporate services for Singapore-registered businesses
Singapore Corporate Services Pte Ltd provides tax accounting and corporate services to businesses operating in Singapore, holding a 4.9/5 rating. The firm covers corporate income tax, GST, and the secretarial functions that accompany ACRA compliance obligations for Singapore private limited companies.
The firm’s name reflects a broad service remit that extends beyond pure tax work into corporate administration. For companies that want a single provider handling both their tax filings and their corporate maintenance obligations, this is a convenient arrangement that avoids the need to maintain relationships with separate accounting and secretarial firms.
Client feedback is consistently positive on the quality of service and the team’s knowledge of Singapore compliance requirements. The 4.9/5 rating places the firm among the stronger-rated general corporate services providers on this list.
Pros
- 4.9/5 client rating
- Combines tax accounting with corporate secretarial services
- Strong knowledge of ACRA and IRAS compliance requirements
- Practical for businesses wanting combined corporate and tax support
Cons
- Generalist positioning may not suit clients with highly specialised tax requirements

15. Counto
Singapore tax accountants for corporate compliance and personal returns
Counto is a Singapore accounting firm covering corporate compliance and personal tax returns, holding a 4.7/5 rating. The firm operates with a technology-assisted model that allows clients to manage their accounting interactions through a platform, which suits businesses that prefer digital document submission and online communication over in-person meetings.
The technology angle is relevant for Singapore SMEs and startups that have adopted cloud-based accounting tools. Counto’s workflow is designed to connect with common bookkeeping platforms, which reduces the manual effort involved in preparing annual tax filings. For businesses already using Xero, QuickBooks, or similar tools, the integration reduces duplication of data entry.
The 4.7/5 rating is solid, and client feedback acknowledges the convenience of the digital-first approach. Businesses that prefer a more traditional relationship model with face-to-face advisory may find the format less suitable, but for efficient annual compliance management, Counto is a well-structured option.
Pros
- 4.7/5 client rating
- Technology-assisted model suits businesses using cloud accounting platforms
- Reduces manual effort through integration with common bookkeeping tools
- Efficient for annual compliance cycles
Cons
- Digital-first model may not suit clients who prefer in-person advisory relationships
- Less suited to complex or bespoke tax situations requiring deep advisory engagement
Best for: Singapore SMEs and startups using cloud accounting tools who want an efficient, tech-assisted compliance service

Who is the best tax accountants in Singapore?
The best firm depends entirely on what you need. For Australian expats, Odin Tax is the most focused option. For US expats, Hayden T Joseph CPA LLP (Advanced American Tax) is the clear specialist. For Singapore corporate tax compliance, firms like AG Singapore, One Tax CM Pte Ltd, and Timcole all hold strong ratings and cover the full compliance cycle. Businesses needing combined corporate secretarial and tax services might consider Koh Management or Singapore Corporate Services. There is no single best firm for all situations, but all 15 firms on this list have demonstrated client satisfaction through verified ratings and reviews.
How much does a tax accountant cost in Singapore?
Fees vary considerably depending on the type of service, the complexity of the engagement, and the size of the firm. For a straightforward Singapore corporate tax return (Form C-S for smaller companies), fees from a smaller firm can start from around SGD 400 to SGD 800 per year. More complex corporate tax work, including transfer pricing documentation or GST audits, will cost significantly more. Personal income tax returns for individuals with straightforward employment income are often handled at lower cost, while expatriate returns involving cross-border obligations (Australian ATO or US IRS filings, for example) carry higher fees reflecting the specialist knowledge required. Bundled packages that combine bookkeeping, secretarial, and tax work typically range from SGD 1,500 to SGD 5,000 per year for SMEs, depending on transaction volume and service scope.
How do I choose a tax accountant in Singapore?
Start by identifying the specific obligations you need help with. If you are a Singapore company, you need someone who handles IRAS corporate tax filings and understands the ECI and Form C or C-S process. If you are an expatriate with home country tax obligations, you need a specialist in that jurisdiction’s rules, not just a general Singapore accountant. Check that the firm or individual is appropriately qualified, ideally as a Chartered Accountant (CA) or Certified Public Accountant (CPA). Review client ratings and, where possible, ask for references from clients with similar needs to yours. Finally, assess the responsiveness during your initial contact; a firm that is slow to reply before you are a client will not improve once you are engaged.
What should I look for in a tax accountant?
Look for relevant qualifications, verifiable experience with clients in similar situations to yours, and clear communication about fees before engagement. A good tax accountant should explain what they are doing and why, not just deliver a completed return without context. For businesses, look for a firm that can advise on tax implications of decisions throughout the year, not just at filing time. For individuals with cross-border obligations, specialisation in the relevant jurisdiction’s rules is more important than general Singapore tax knowledge. Reliable response times and a clear process for document submission and query resolution are practical qualities worth assessing during the selection process.
Are there good tax accountants for small businesses in Singapore?
Yes, and several on this list are specifically well-suited to small businesses. Koh Management, J Accounting Pte. Ltd., One Accounting Services Singapore, and Fryday all position themselves for SMEs and smaller operators. Timcole and Counto also serve small businesses effectively, with Counto’s technology-assisted model particularly suited to startups and early-stage companies using cloud accounting platforms. Small businesses should look for firms that offer bundled compliance packages covering bookkeeping, GST, and corporate tax, as these typically provide better value than paying for each service separately. All of these firms carry ratings of 4.8 or above from verified client reviews, which provides reasonable confidence in their service quality.
Finding the right tax accountant in Singapore comes down to matching the firm’s specific capabilities to your actual obligations. Expats with Australian or US tax requirements need specialists, not generalists. Singapore companies at the compliance stage need reliable annual filing support with transparent pricing. Growing businesses benefit from firms that can engage on planning questions, not just return preparation. The 15 firms on this list cover all of these needs, and all have earned their place here through demonstrated client satisfaction and service quality.
