Accounting Services Prices in Singapore: 2026 Monthly Fees

Most Singapore SMEs pay S$300 to S$2,000 a month for accounting services. Where you land depends on your transaction volume, whether you are GST-registered, and how much of the work sits inside one fee. But the monthly retainer is only part of the story. Miss a GST deadline and you face a S$200 instant penalty. Under-claim your tax deductions and you leave money with IRAS every year. Spend five hours a month on your own bookkeeping and you have quietly spent S$1,000 worth of your own time, assuming your time is worth S$200 an hour.

This guide breaks down every pricing model available to Singapore business owners, what is actually included in each, and how to work out which option gives you the best return, not just the lowest quote.

What "Accounting Costs" Actually Covers

Accounting services for Singapore SMEs typically bundle several distinct functions into one engagement:

• Bookkeeping: recording transactions, bank reconciliation, categorising expenses, and management accounts
• Annual Financial statements: prepared under Singapore Financial Reporting Standards (FRS), requiring expert accounting knowledge to ensure correctness
• Tax filing: estimated chargeable income (ECI) and annual corporate income tax (Form C-S or Form C)
• GST filing: quarterly returns if your business is GST-registered
• Payroll processing: CPF calculations, payslips, and IR8A returns
• Corporate secretarial: ACRA annual return, AGM documentation, and statutory registers

Some providers bundle all of these into a single retainer. Others quote each service separately. Understanding what is in your package, and what is not, is the first step to comparing costs fairly.

The Four Accounting Models and What Each Costs

1. DIY (Accounting Software Only)

If you manage your own books using cloud software, your main cost is the subscription. Platforms like Xero are the standard in Singapore, with monthly plans to suit different transaction volumes.

What you save: professional fees entirely, for simple businesses.

What it costs you: typically 3 to 8 hours per month of your own time for basic bookkeeping. For a founder billing at S$200 per hour, that is S$600 to S$1,600 worth of executive time going into reconciling accounts each month. You also carry the compliance risk: missed deductions, miscategorised expenses, and filing errors that accumulate silently.

Best for: sole proprietors and early-stage businesses with fewer than 20 transactions per month and no GST registration.

2. Freelance Bookkeeper

A freelance bookkeeper typically charges by the hour or by transaction volume, handling data entry and bank reconciliation without providing tax filing or compliance support.

Typical cost: S$100 to S$500 per month, depending on transaction volume.

What you still need to arrange separately: tax filing, GST returns, corporate secretarial work, and IRAS correspondence. Each of these adds cost and coordination time on top of the bookkeeping fee.

Best for: cost-conscious businesses comfortable managing compliance themselves, or those who already have a part-time accountant handling filings.

3. Traditional Accounting Firm

A conventional firm charges separately for each engagement: a retainer for bookkeeping, separate fees for tax filing, and additional charges for GST, payroll, and secretarial work.

Typical costs:

• Monthly bookkeeping retainer: S$300 to S$1,000 per month
• Annual tax filing: S$400 to S$1,200 per engagement
• GST filing: S$300 to S$800 per quarter
• Payroll processing: S$20 to S$50 per employee per month

The itemised model means the relationship tends to be transactional. You file, they submit, and everyone moves on. Strategic input is rarely included, and fees tend to increase as your business grows in complexity.

Best for: businesses that prefer itemised billing and want an established, separate firm for each function.

4. Cloud Accounting Firm (Outsourced, Fixed Fee)

Cloud-first firms bundle bookkeeping, tax filing, GST returns, and financial reporting into a single monthly retainer. The all-inclusive model means no surprise invoices when tax season arrives.

Typical cost: S$300 to S$2,000 per month on a fixed fee, scaling with transaction volume and the services bundled in.

At Harvest Accounting, pricing starts at S$300 per month, including your Xero subscription, and scales with complexity, not with how many questions you ask. You get clean books, accurate filings, and a team that knows your business.

Best for: growing businesses that want proper financial visibility and compliance handled end-to-end, without the overhead of an in-house hire.

Ranges based on Singapore market pricing, 2026. Actual costs depend on transaction volume, headcount, and GST registration status.

The Hidden Costs Most Business Owners Miss

The sticker price of accounting is rarely the complete picture. Here are the costs that do not appear in any fee schedule.

IRAS Penalties

Late GST filing carries an immediate S$200 penalty, plus S$200 for every full month the return remains outstanding, capped at S$10,000 per return. Late payment on top of that adds a 5% surcharge on the outstanding GST amount.

For corporate income tax, IRAS can offer a composition amount of up to S$5,000 per offence for a late return, depending on your company's compliance record (IRAS). IRAS may also raise an estimated assessment at a higher figure than your actual taxable income, requiring you to pay first and dispute later.

These are not theoretical risks. They are standard IRAS enforcement actions for businesses without consistent accounting support.

Missed Tax Deductions

Singapore companies can deduct a broad range of business expenses against taxable income, including software subscriptions, professional development, business meals, and renovation costs under certain conditions. As the IRAS guidelines on business expenses make clear, the deductions are legitimate, but only if expenses are correctly categorised at source.

Businesses managing their own books, or using underqualified bookkeepers, regularly miss these deductions because the transactions are never coded correctly. If your taxable profit is S$150,000 and you miss S$25,000 in legitimate deductions, you are paying corporate income tax on income that never needed to be taxed.

The True Cost of an In-House Hire

Thinking about hiring an accountant? The full cost is rarely just the salary. For a junior accountant on S$4,000 per month base:

1. Gross salary: S$4,000 per month
2. Employer CPF contribution: approximately S$680 per month (17% for employees aged 55 and below; see CPF Board guidelines)
3. AWS, bonuses, and benefits: approximately S$500 to S$800 per month equivalent
4. Recruitment cost amortised over tenure: approximately S$200 per month
5. Annual leave cover and training: approximately S$150 per month

Total effective cost: S$5,530 to S$5,830 per month, or S$66,000 to S$70,000 per year, for one person covering limited hours.

For most SMEs with revenue under S$5M, outsourcing delivers broader coverage, better technology infrastructure, and lower compliance risk at a fraction of this cost.

How to Choose the Right Accounting Model

Work through these questions in order:

1. How many transactions does your business process per month? Fewer than 30 transactions: DIY is feasible. More than 50: professional support will save time and meaningfully reduce risk.
2. Are you GST-registered, or approaching the S$1 million threshold? If yes, quarterly filing compliance is not optional, and errors are costly.
3. Do you have employees? Payroll adds complexity: CPF calculations, Skills Development Levy (SDL), IR8A returns, and monthly obligations that repeat without exception.
4. How often do you look at your financials? If the answer is "only at tax time," a good accounting firm will change that, and you will make better decisions as a result.
5. What is an hour of your time worth? If you earn more per hour than you would spend on professional accounting, the math strongly favours outsourcing.

Frequently Asked Questions

How much does accounting cost for a startup in Singapore? Most early-stage companies with low transaction volumes and no employees spend S$300 to S$500 per month on a full-service package covering bookkeeping, tax filing, and ACRA compliance in one fixed fee.

What is the difference between a bookkeeper and an accountant in Singapore? A bookkeeper records transactions and reconciles bank accounts. An accountant analyses those records, prepares financial statements, advises on tax positions, and files with IRAS and ACRA. Most Singapore SMEs need both functions, which is why cloud accounting firms bundle them into a single engagement.

Is accounting software enough for a Singapore company? Software handles data entry efficiently, but it does not file your taxes, advise on deductions, or respond to IRAS queries on your behalf. For small, low-activity businesses with no compliance obligations, software alone may be sufficient. For any business with employees, GST registration, or growth ambitions, professional support is strongly recommended.

Can I claim accounting fees as a tax deduction in Singapore? Yes. Professional fees paid to accountants, bookkeepers, and corporate secretaries are deductible business expenses under the Income Tax Act, provided they are incurred wholly and exclusively in the production of income.

What should a good accounting retainer include in Singapore? At minimum: monthly bookkeeping, bank reconciliation, management accounts, annual corporate tax filing, and ACRA compliance. A thorough provider will also include GST filing (if registered), payroll processing (if applicable), and regular financial reporting. Always clarify what triggers additional charges before signing. Bundling these into a single outsourced accounting retainer is usually cheaper than buying each service on its own.
