10 Best Accounting Firms in Singapore (August 2026)

An accounting firm handles the financial compliance and reporting that every Singapore company is legally required to maintain. At a minimum, that includes bookkeeping (recording your transactions), preparing annual financial statements that comply with Singapore Financial Reporting Standards (SFRS), filing your Estimated Chargeable Income (ECI) and corporate tax return (Form C-S or Form C) with IRAS, and ensuring your company meets its statutory obligations under the Companies Act.

Beyond the basics, most firms bundle additional services that growing businesses need:

• GST registration and quarterly filing (mandatory once your taxable turnover exceeds S$1 million)
• Payroll processing including CPF contributions, IR8A forms, and leave management
• Corporate secretarial services including AGM filings, annual returns with ACRA, and maintenance of statutory registers
• Tax advisory covering deductions, incentives, and structuring (especially relevant for companies with cross-border operations)
• Audit coordination for companies that meet the audit threshold (revenue above S$10 million, assets above S$10 million, or more than 50 employees)

The key distinction to understand before comparing quotes: basic compliance (bookkeeping + annual filing) costs S$60 to S$400 per month. Full-service packages that include tax, payroll, GST, and corporate secretarial typically run S$250 to S$1,200 per month depending on your transaction volume and complexity. Know which level of support you need before you start calling around.

Choosing an accounting firm is not just a cost decision. The wrong firm costs you more in the long run through missed deductions, late filings, and financial reports that tell you nothing useful. Here is what to evaluate:

1. Match the firm tier to your business stage. A solo founder with 15 transactions a month does not need RSM. A company preparing for an IPO does not need a S$75-per-month platform. Budget providers (S$60 to S$400/month) suit startups and micro-businesses. Mid-range firms (S$300 to S$1,200/month) suit SMEs with employees, GST obligations, and growing complexity. Mid-tier firms (S$1,000 to S$5,000/month) suit established companies needing audit, advisory, and international capability.
2. Ask for the total annual cost, not just the monthly fee. The most common source of frustration with accounting firms is unexpected charges. A firm quoting S$200 per month might charge separately for GST returns, year-end financial statements, corporate tax filing, and XBRL preparation. Get a full breakdown before you sign.
3. Check their technology stack. Cloud accounting is the baseline expectation in 2026. Your firm should work with platforms like Xero or QuickBooks, both of which support GST filing and InvoiceNow (Peppol) integration. If a firm is still emailing you Excel spreadsheets, they are behind the curve.
4. Verify qualifications. At minimum, your accountant should hold ACCA, CPA, or ISCA accreditation. For audit services, the firm must be registered with ACRA. Check their registration status on the ACRA website before committing.
5. Test their responsiveness before you sign. Send an enquiry. How fast do they reply? Is the response generic or tailored to your question? The way a firm handles pre-sales communication is exactly how they will handle your account when you need them during tax season.

Also think about whether you need a firm that bundles corporate secretarial services. Under the Singapore Companies Act, every company must appoint a corporate secretary within six months of incorporation. Having your accountant and corporate secretary under one roof simplifies compliance and reduces the number of providers you need to manage.

And once you have your accounting sorted, your website is the next piece of the puzzle. We have worked with professional service firms across Singapore, including Kingsman & Associates, where we delivered a premium corporate website in just 2 weeks. A strong online presence is what separates accounting firms that attract high-value clients from those competing on price alone. If that is something on your radar, our web design services are built specifically for Singapore businesses.

Accounting services in Singapore range from S$60 to over S$5,000 per month depending on the level of service and the type of firm you choose. Here is a realistic breakdown for 2026:

• Basic bookkeeping only: S$60 to S$300/month. Covers transaction recording and bank reconciliation. Suitable for dormant companies, holding companies, or very early-stage startups with minimal activity.
• Full compliance package (bookkeeping + tax + annual filing): S$250 to S$800/month. The sweet spot for most SMEs. Includes bookkeeping, preparation of unaudited financial statements, ECI filing, corporate tax return, and management reports.
• Full-service with GST, payroll, and corporate secretary: S$500 to S$1,200/month. For businesses with employees, GST obligations, and more complex reporting needs. Bundling everything under one provider typically costs less than engaging separate specialists.
• Mid-tier firm (audit-ready): S$1,000 to S$5,000/month. Includes everything above plus audit services, tax advisory, and direct partner access. Suited for companies with revenue above S$1 million or those approaching the statutory audit threshold.
• Big Four (Deloitte, PwC, KPMG, EY): S$5,000 to S$20,000+/month. For multinational corporations, publicly listed companies, and businesses needing international tax structuring, M&A advisory, or IPO preparation.

The factors that push your bill higher include transaction volume (more invoices means more processing time), number of employees on payroll, GST-registered status (quarterly filing adds complexity), multi-currency operations, and the need for management reporting beyond basic compliance. Always ask for an itemised quote that covers the full year, not just the monthly retainer.

Yes. Every Singapore company must file annual financial statements with ACRA and submit a tax return to IRAS, even if you have zero revenue. A dormant company still has filing obligations. Most accounting firms offer low-cost dormant company packages (S$300 to S$800 per year) that handle these requirements without you having to think about them.

A bookkeeper records your day-to-day transactions: invoices, receipts, bank entries, and reconciliations. An accountant takes those records and prepares financial statements, files your taxes, provides advisory on deductions and structuring, and ensures regulatory compliance. Most SMEs need both, which is why full-service firms bundle bookkeeping and accounting together.

A Singapore company requires a statutory audit if it meets any two of these three criteria for two consecutive years: annual revenue above S$10 million, total assets above S$10 million, or more than 50 employees. Companies below these thresholds are exempt from audit but still need to prepare unaudited financial statements.

Digital platforms (Osome, Sleek, Counto) are best for startups with straightforward needs, low transaction volumes, and tight budgets. Traditional firms (Harvest, OneStop, Koh Management) are better when you need personal attention, industry-specific advice, or complex tax planning. Many businesses start with a digital platform and transition to a traditional firm as they grow. Neither approach is universally better; it depends on your stage and priorities.

Most firms on this list offer corporate secretarial services, typically priced at S$300 to S$1,200 per year. Bundling both services under one provider simplifies compliance, reduces the number of vendors you manage, and often comes at a discount compared to engaging separate providers. Given that corporate secretary appointment is mandatory under the Companies Act, this is a practical bundling decision.

Not every accounting firm deserves your business. After reviewing dozens of providers for this article, here are the warning signs that should give you pause:

• No clear pricing on their website. Legitimate firms are transparent about their fee structure. If a firm makes you fill out a contact form before revealing any pricing information, they are either overpriced or planning to upsell you during the sales call. The best firms publish at least a starting price range.
• Quoting per transaction without a cap. Per-transaction billing punishes growth. As your business scales and transaction volumes increase, your accounting bill grows disproportionately. Look for firms that offer flat monthly fees or revenue-based pricing with unlimited transactions.
• No ACRA registration. Any firm providing corporate secretarial or filing agent services must be registered with ACRA. Verify their registration before engaging. An unregistered provider handling your ACRA filings is a compliance risk you do not need.
• Slow response times before you sign. If a firm takes five days to respond to a sales enquiry, imagine how long they will take when you have a tax deadline approaching. Test responsiveness early. A good firm replies within 24 hours.
• No named accountant on your account. Some budget providers route your queries through a general support queue with no dedicated point of contact. That works for simple questions, but when you need someone who understands your business context (especially during tax season or an audit), having a named accountant matters.
• Outdated technology. If the firm asks you to email scanned receipts or submit documents via USB drive, they are not keeping pace with modern accounting practices. Cloud-based platforms, bank feed integrations, and digital receipt capture are standard in 2026.

Your accountant is one of the most important professional relationships your business will have. Take the time to vet them properly, the cost of getting it wrong is far higher than the effort of choosing well.
