Prices in Singapore Dollars (SGD). Last updated 2026.
Tax accounting in Singapore covers a wide range of services: corporate income tax filing with IRAS, GST registration and quarterly submissions, preparation of unaudited financial statements, bookkeeping, payroll processing, and corporate secretarial work required by ACRA. For many business owners, especially those running small or early-stage companies, all of these obligations arrive at once and need to be managed on an ongoing basis rather than as a one-off annual task.
Costs vary significantly depending on transaction volume, business complexity, the number of employees on payroll, and whether you need monthly bookkeeping or just yearly compliance support. A sole proprietor with minimal transactions will pay far less than a growing SME processing hundreds of transactions per month across multiple revenue streams. Understanding what drives these differences helps you budget accurately and avoid paying for services you do not need.
What Do Tax Accountants Cost in Singapore?
Most Singapore SMEs pay between SGD 300 and SGD 800 per month for outsourced accounting services that include bookkeeping, corporate tax filing, and basic compliance. At the lower end, early-stage companies with revenue under SGD 500,000 and fewer than 50 transactions per month can often find fixed-fee packages starting around SGD 150 to SGD 250 per month. These typically cover data entry, basic financial reporting, and annual corporate tax return preparation. GST filing, payroll, and corporate secretarial work are usually charged separately and can add SGD 100 to SGD 400 per month depending on volume and frequency.
Hourly rates for qualified tax accountants at traditional accounting firms in Singapore range from SGD 75 to SGD 200 per hour. Project-based fees for a standalone corporate tax filing start around SGD 400 to SGD 1,000 for a simple company with clean records. Businesses with more complex structures, multi-currency transactions, or international related-party dealings can expect corporate tax preparation fees from SGD 1,500 to SGD 3,000 or more per engagement. Monthly retainer arrangements are more cost-effective for businesses that need ongoing support rather than ad hoc work.

What Affects the Cost of Tax Accountants in Singapore?
Transaction volume and bookkeeping complexity
The single biggest pricing factor for ongoing accounting services is how many transactions your business processes each month. Firms price packages by transaction bands, typically under 50, 50 to 150, 150 to 300, and 300 or more. Each band increase raises your monthly fee. Businesses with e-commerce operations, multiple payment gateways, or high-frequency sales generate far more data entry work than a simple service-based company billing a handful of clients each month.
GST registration status
Once your business crosses the SGD 1 million revenue threshold, GST registration becomes mandatory. Quarterly GST filing adds to your accounting workload and cost. Firms typically charge between SGD 100 and SGD 300 per quarter for GST preparation and submission, depending on the number of input and output tax entries involved. Companies voluntarily registering for GST before hitting the threshold face the same ongoing cost.
Payroll and employee headcount
Payroll processing is almost always priced separately from bookkeeping and tax filing. Expect to pay SGD 15 to SGD 40 per employee per month for payroll services, covering CPF calculations, payslip generation, and annual IR8A submissions to IRAS. As your headcount grows, this becomes a meaningful line item in your total accounting spend.
Business structure and compliance requirements
All Singapore-incorporated companies, regardless of size, require unaudited financial statements prepared in accordance with Singapore Financial Reporting Standards, an annual return filed with ACRA, and a corporate income tax return submitted to IRAS. Companies with more complex structures, such as those holding intellectual property, receiving foreign income, or making related-party transactions, need additional tax analysis and documentation that increases fees substantially.
Firm type and technology use
Traditional accounting firms with physical offices and dedicated human accountants generally charge more than cloud-based or tech-enabled providers using automated bookkeeping software. Cloud providers often pass on some efficiency gains through lower monthly fees, particularly for straightforward businesses. That said, complex tax matters still require experienced human review, and very low-cost providers may lack the expertise to handle anything beyond basic compliance without significant additional charges.
How to Get Accurate Quotes
- Prepare a summary of your business before contacting providers. Include your annual revenue, average monthly transaction volume, whether you are GST-registered, how many employees you have, and whether you need corporate secretarial services. Firms need this information to give a fixed-fee quote rather than a vague estimate.
- Ask specifically whether the quoted price is all-inclusive or whether GST filing, payroll, ACRA annual returns, and corporate tax filing are billed separately. Many providers advertise a low monthly bookkeeping fee but charge additionally for every compliance task.
- Request a breakdown of what triggers additional fees. Common extras include catch-up bookkeeping for prior periods with incomplete records, late filing penalties passed through to clients, and ad hoc tax advisory calls billed at hourly rates.
- Compare at least three providers across different firm types: a traditional accounting firm, a cloud-based provider, and a mid-sized boutique firm. This gives you a realistic picture of the market rate for your specific situation and avoids anchoring on the first quote you receive.
- Check that the provider is registered with the Institute of Singapore Chartered Accountants (ISCA) or employs CPA-qualified accountants. For tax advisory work, confirm the accountant has relevant experience with IRAS tax positions relevant to your industry.
Red Flags to Watch Out For
- Quotes with no transaction volume limit attached. Any fixed-fee package without a clear transaction cap means the provider can argue for additional charges later once your volume becomes apparent.
- Providers who cannot clearly explain whether corporate secretarial, GST filing, and tax filing are included or separate. Legitimate firms quote transparently. Vague scoping is how unexpected invoices appear at year-end.
- Very low monthly fees, below SGD 100 per month, for a company with active operations. This signals either a severely limited service scope or a provider relying on upselling and ad hoc billing to make the engagement profitable.
- No mention of IRAS or ACRA filing deadlines in the engagement agreement. A professional firm will proactively manage your compliance calendar. If the provider puts all filing responsibility back on you, the service has limited practical value.
- Slow or inconsistent communication during the quoting stage. Tax compliance has hard deadlines. A provider who takes days to respond to basic questions before you have signed is unlikely to be more responsive once they have your business.
- Firms that cannot produce sample financial statements or explain the difference between Form C and Form C-S. This is entry-level knowledge for Singapore corporate tax. Gaps here suggest a lack of local regulatory experience.
Frequently Asked Questions
How much do tax accountants cost in Singapore on average?
For an active SME in Singapore, the average total spend on outsourced accounting services sits between SGD 400 and SGD 800 per month when you include bookkeeping, corporate tax filing, and GST compliance. Very small or early-stage companies with minimal transactions can manage with packages starting around SGD 150 to SGD 250 per month for basic bookkeeping and annual tax preparation. Businesses with employees, GST obligations, and growing transaction volumes typically move into the SGD 600 to SGD 1,200 per month range once all required services are included.
Why are some tax accountants prices so much cheaper?
Lower prices usually reflect one of three situations: a very narrow service scope covering only one task such as annual tax filing with no ongoing bookkeeping, the use of automated software with minimal human review, or providers targeting very small companies with clean and simple records. The risk with very low-cost options is that anything outside the narrow scope gets billed separately, often at high hourly rates, or is simply not done. Incomplete records, missed GST filings, or incorrectly prepared financial statements can result in IRAS penalties and ACRA late filing fees that cost far more than the savings on the original accounting bill.
Is it worth paying more for tax accountants in Singapore?
For most growing businesses, yes. A qualified tax accountant who understands Singapore’s corporate tax system, knows the relevant IRAS concessions available to SMEs, and keeps your books clean throughout the year saves time, reduces compliance risk, and provides financial statements you can actually use for business decisions. The cost of fixing incorrectly filed returns, managing a late filing penalty, or reconstructing a year of poor records almost always exceeds the difference in fee between a basic and a mid-range provider. Paying SGD 500 to SGD 800 per month for a complete and professionally managed accounting function is a reasonable cost for a company generating SGD 500,000 or more in annual revenue.
Choosing the right tax accountant in Singapore comes down to matching the provider’s service scope and expertise to the actual needs of your business, not simply finding the lowest monthly fee. Get specific quotes, confirm exactly what is included, and factor in the cost of GST filing, payroll, and corporate secretarial work before making a final comparison. A transparent, fixed-fee provider with clear deliverables and a track record with IRAS compliance will almost always deliver better value than a cheaper option with a vague scope and unpredictable billing.
