10 Best Accounting Firms in Singapore (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.

If you want accounting that feels like using an app rather than emailing a bookkeeper, Osome is the firm to look at. Founded as a digital-first platform, Osome automates the tedious parts of compliance (receipt capture, bank feed reconciliation, invoice matching) and layers human accountants on top for the work that still requires professional judgement. Their mobile app lets you snap receipts, track expenses, and view financial dashboards in real time, which is genuinely useful for founders who want visibility without waiting for monthly reports.

Where Osome stands out is their focus on e-commerce businesses. They handle multi-currency bookkeeping, platform integrations (Shopify, Amazon, Stripe), and the GST complexities that come with cross-border selling. For startups burning through their seed funding and needing to keep investors updated with clean financials, Osome is a solid match. Their Operate plan starts at S$75 per month (billed annually at S$816) and includes bookkeeping, ECI filing, unaudited financial statements, and corporate tax submission.

The trade-off is that Osome is a platform, not a relationship. You will not get a dedicated partner who knows your business inside out. Customer service reviews are mixed; some clients praise the efficiency, others find the support less personal than a traditional firm. If you value face-to-face meetings and a named accountant who picks up the phone, this may not be the right fit. But for cost-conscious founders who are comfortable with digital tools, the value is hard to beat.

Best for: Tech startups and e-commerce businesses wanting automated, app-based accounting.
Pricing: From S$75/month (Operate plan); S$99/month (Grow); S$227/month (Scale with dedicated accountant and GST filing).
Standout strength: Purpose-built for e-commerce with multi-currency support, platform integrations, and real-time financial dashboards.

Sleek has built its reputation as the one-stop shop for founders setting up in Singapore. Company incorporation, corporate secretary, accounting, tax filing, work visas: they bundle everything under transparent pricing with no hidden fees. For foreign entrepreneurs incorporating a Singapore company, Sleek is particularly strong because they offer nominee director services alongside their accounting packages, which means one provider handling your entire compliance stack from day one.

Their accounting services cover bookkeeping, preparation of unaudited financial statements, ECI and corporate tax filing, and management reports. They use Xero as their primary platform, and their onboarding process is designed to be fast and paperless. Incorporation packages for local founders start from S$600 (including the S$315 ACRA government fee), with corporate secretarial services from S$300 per year for single-shareholder companies.

Sleek is best suited for early-stage businesses with straightforward accounting needs. If your company has high transaction volumes, complex multi-entity structures, or needs deep tax advisory, you may outgrow their standard packages. But for startups and small businesses that want everything handled by one provider at a predictable cost, Sleek removes a lot of the friction that comes with juggling multiple service providers.

Website: sleek.com/sg
Best for: Founders (especially foreign entrepreneurs) who want incorporation, accounting, and compliance bundled under one roof.
Pricing: Incorporation from S$600; corporate secretary from S$300/year; accounting packages from approximately S$150/month.
Standout strength: End-to-end company setup and compliance for foreign founders, including nominee director and work visa support.

Harvest Accounting was founded in 2018 with a simple premise: build an accounting firm that is 100% cloud-based from day one. That decision paid off. They won "Medium Accounting Partner of the Year" at the Xero Singapore Awards in 2023, and in 2025 they took home both "Digital Innovator of the Year" and "Partner of the Year (Singapore)" at the Xero Asia Awards. If you are already using Xero (or planning to), Harvest is one of the most qualified firms to manage your books on it.

What makes Harvest different from other Xero-based firms is their emphasis on financial insight, not just compliance. Their monthly reporting goes beyond the standard profit-and-loss statement; they provide management dashboards using tools like Futrli that give you real-time visibility into cash flow, margins, and key performance indicators. For business owners who actually want to use their financials to make decisions (rather than just filing them away for IRAS), that level of reporting is valuable.

Pricing starts from S$300 per month for monthly reporting, annual financial statements, and tax filing, with Xero and Dext (formerly Receipt Bank) subscriptions included. That positions Harvest in the mid-range, which reflects the quality of their reporting and advisory work. They are particularly well-suited to service businesses, F&B operators, and SMEs with 5 to 50 employees who need more than basic bookkeeping but are not ready for a mid-tier audit firm.

Website: harvestaccounting.com.sg
Best for: SMEs wanting cloud-native accounting with insightful management reporting and Xero expertise.
Pricing: From S$300/month including Xero and Dext subscriptions, monthly reporting, and annual tax filing.
Standout result: Winner of Xero Asia "Partner of the Year (Singapore)" and "Digital Innovator of the Year" in 2025.

Counto was founded by two computer engineers, and it shows. Their entire pricing model is built to eliminate the most common complaint about accounting firms: unexpected fees. Instead of charging per transaction (which penalises growing businesses), Counto uses revenue-based pricing with unlimited transactions included. Your monthly fee is tied to your company's annual revenue, not the number of invoices you process. For businesses with high transaction volumes, like e-commerce stores or F&B operations, that pricing model can save a significant amount compared to traditional per-transaction billing.

Their technology stack is equally notable. Counto's proprietary tax system has achieved IRAS ASR+ Tier 3 qualification, the highest possible accreditation in Singapore. That means their automated tax calculations and filings meet the strictest standards the tax authority sets. Their all-inclusive plans cover bookkeeping, tax preparation, GST filing, corporate secretary (from S$325 per year), and even payment processing through a unified dashboard.

The limitation is that Counto is best suited for straightforward compliance needs. If you require complex tax structuring, cross-border advisory, or audit services, you will need a firm with deeper advisory capabilities. But for SMEs that want a predictable monthly bill, unlimited transactions, and the peace of mind that comes with IRAS's highest accreditation, Counto is a smart choice.

Website: counto.sg
Best for: High-transaction businesses (e-commerce, F&B, retail) wanting predictable, volume-friendly pricing.
Pricing: Revenue-based plans with unlimited transactions; corporate secretary from S$325/year.
Standout strength: First firm in Singapore to offer unlimited transactions with revenue-based pricing; IRAS ASR+ Tier 3 qualified tax system.

3E Accounting has been around for over 15 years and has built a reputation as one of Singapore's most accessible corporate service providers. They are ACCA-approved, ACRA-registered, and offer the kind of all-in-one service package that startup founders need when they are too busy building their product to think about compliance. Company incorporation, accounting, tax, payroll, corporate secretary, and even immigration services all sit under one roof.

Their pricing is aggressive. Company incorporation starts from the S$315 ACRA government fee with corporate secretary included, and their accounting packages are among the most affordable in the market. Payroll processing runs at S$65.40 per employee per month. For founders bootstrapping their way through the early stages, 3E lets you tick every compliance box without burning through your operating budget.

The trade-off with budget pricing is what you would expect. You will not get the same depth of advisory or reporting that mid-tier firms provide, and some clients have noted that communication can be transactional rather than consultative. If you need strategic tax planning or sophisticated financial analysis, 3E is not the right fit. But if you need reliable, affordable compliance handled by a firm that has served thousands of startups and SMEs across Singapore, they deliver on that promise consistently.

Website: 3ecpa.com.sg
Best for: Early-stage startups needing affordable, no-frills incorporation and compliance services.
Pricing: Incorporation from S$315 (govt fee); payroll at S$65.40/employee/month; accounting packages among the lowest in Singapore.
Standout strength: 15+ years in business, ACCA-approved, with one of the broadest service bundles at the budget tier.

AG Singapore occupies a sweet spot that many growing businesses need: mid-tier expertise without mid-tier bureaucracy. They are an award-winning firm that has served more than 1,000 clients, sitting in the niche between larger professional services networks and smaller local practices. If your company has outgrown a basic bookkeeping provider but does not need (or want to pay for) a Big Four firm, AG is worth a serious look.

Their standout feature is speed. AG delivers audit and financial review services within 2 to 4 weeks, which is roughly 50% faster than the industry standard of 4 to 8 weeks. For businesses approaching deadlines or going through due diligence for a transaction, that turnaround time is a genuine competitive advantage. They also maintain a 96.5% customer satisfaction rate, which is high for a firm handling the volume of work they do.

What I appreciate about AG's model is its flexibility. Their service is not contractual in the traditional sense; you can add or remove accounting requirements as your business needs change, and you pay only for what you use rather than being locked into bundled packages. That suits project-based businesses and companies with seasonal fluctuations particularly well. They cover bookkeeping, compliance, tax, and audit services across Singapore and Malaysia.

Website: ag-singapore.com
Best for: Growing SMEs that need audit services and flexible, contract-free accounting support.
Pricing: Custom quotes based on scope; no lock-in contracts.
Standout result: 96.5% customer satisfaction rate; audit delivery 50% faster than industry standard (2 to 4 weeks vs 4 to 8).

RSM Singapore is the largest professional services firm outside the Big Four in Singapore, and a member of RSM International, the world's sixth-largest professional services network with firms in over 120 countries and combined revenues exceeding US$10 billion. That global footprint matters if your business operates across borders, is planning international expansion, or needs transfer pricing advisory that smaller firms simply cannot provide.

Their service range is comprehensive: assurance, tax, corporate advisory, risk advisory, business process outsourcing, corporate secretarial, payroll, recruitment, and IT consulting. For companies preparing for an IPO or navigating complex group structures, RSM brings the depth of expertise you would expect from a Big Four firm but with direct partner access and mid-tier pricing. Their accounting outsourcing team specifically caters to SMEs, handling everything from routine bookkeeping to management reporting and financial analysis.

RSM is not the cheapest option, and they are not designed to be. Mid-tier firms in Singapore typically charge S$1,000 to S$5,000 per month, reflecting the seniority of the professionals working on your account. If you are a solo founder with 20 transactions a month, RSM is more firepower than you need. But if your annual revenue is in the S$1 million to S$10 million range and you need a firm that can grow with you through audits, tax structuring, and eventual expansion, RSM is the natural step up from SME-focused providers.

Website: rsm.global/singapore
Best for: Established SMEs, IPO-track companies, and businesses with international operations needing a global network.
Pricing: Mid-tier range, typically S$1,000 to S$5,000/month depending on scope and complexity.
Standout strength: Largest non-Big Four firm in Singapore; member of a 120-country, US$10 billion global network.

Grof (formerly Sprout Asia) has repositioned itself as an all-in-one corporate services platform for businesses that are past the startup phase and into genuine growth. Their rebranding reflects a broader service offering: accounting, tax, corporate secretarial, payroll, and business advisory, all delivered through a modern digital platform with transparent pricing and no hidden fees.

What makes Grof particularly suitable for growing businesses is their understanding of the transition point. When your company moves from "founder doing everything" to "we need proper systems," the accounting requirements change dramatically. You need management reports that actually inform decisions, GST compliance as revenue crosses the S$1 million threshold, payroll processing for a team that is hiring fast, and corporate secretarial support for board resolutions and share allotments. Grof packages these services so you can add what you need without switching providers.

Their team includes chartered accountants, and all financial statements are reviewed by qualified professionals. Pricing is transparent and structured by business stage, which means you are not overpaying for enterprise-level service when you only need SME-level support. If your business is in that S$500,000 to S$5 million revenue range and you need a provider that scales without the friction of re-onboarding every time your needs change, Grof is a sensible pick.

Website: grof.co/sg
Best for: Growth-stage businesses transitioning from basic compliance to structured financial management.
Pricing: Transparent, staged pricing; contact for current rates.
Standout strength: Scalable service model that grows with your business, from basic compliance to full financial management.

OneStop Professional Services has built its reputation on something that digital-first platforms struggle to replicate: genuine, hands-on client relationships. With over 10 years of experience serving both local businesses and foreign entrepreneurs, OneStop takes a consultative approach where you actually speak to the accountant handling your books, not a chatbot or a generic support queue.

Their team is accredited by ACCA, ICAEW, CPA Australia, and ISCA, which is a strong set of credentials for a firm of their size. They use cloud accounting platforms including Xero and AutoCount Cloud, with direct integration to Singaporean banking institutions and the InvoiceNow (Peppol) network. Their accounting services deliver clean, audit-ready books and monthly management reports with KPI tracking, which is a step above what many budget providers offer.

Client reviews consistently highlight two things: responsiveness and proactiveness. OneStop holds a 100% recommendation rating on Facebook from 44+ reviews, and clients report that the team anticipates compliance deadlines and filing requirements rather than waiting to be chased. For business owners who want an accountant they can call, who knows their business by name, and who flags issues before they become problems, OneStop delivers that level of personal service.

Website: onestop-ca.com
Best for: Business owners who value a personal, consultative relationship with their accountant.
Pricing: Competitive mid-range; contact for a customised quote.
Standout strength: 100% recommendation rating; accredited by ACCA, ICAEW, CPA Australia, and ISCA; Xero Silver Partner.

Koh Management is a family business with over 40 years of experience in Singapore's corporate services industry. In a market full of venture-backed startups and digital platforms, there is something reassuring about a firm that has been quietly and competently serving businesses for four decades. They have seen every economic cycle, every regulatory change, and every compliance curveball that ACRA and IRAS have thrown at Singapore businesses.

Their service covers the full spectrum: accounting, taxation, audit coordination, company incorporation, corporate secretarial, payroll management, and business advisory. Financial statements are prepared according to Singapore Financial Reporting Standards (SFRS), and their quarterly accounting service package is specifically designed for SME compliance, delivering clean, organised, audit-ready books. They also offer bookkeeping at quarterly intervals, which reduces costs for businesses with lower transaction volumes.

Clients describe Koh Management as patient, efficient, and reliable, with clear communication that makes complex financial matters easy to understand. If you are an established SME owner who wants a firm that treats your business like a long-term relationship rather than a monthly subscription, Koh Management offers that stability. They may not have the slickest app or the most aggressive marketing, but they have the track record and the depth of experience that newer firms simply have not had time to build.

Website: shkoh.com.sg
Best for: Established SMEs wanting a dependable, long-term accounting partner with deep local experience.
Pricing: Competitive; quarterly and annual accounting packages available. Contact for quote.
Standout strength: 40+ years in Singapore's corporate services industry; family-run firm with deep institutional knowledge.

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.

Do I need an accountant if I just incorporated my company?

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.

What is the difference between a bookkeeper and an accountant?

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.

When does my company need an audit?

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.

Should I use a digital platform or a traditional accounting firm?

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.

Can my accounting firm also handle corporate secretary duties?

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.
