10 Best Accounting Services for Small Businesses in Singapore (2026)

Running a small business in Singapore means dealing with IRAS, GST, annual filings, and that growing pile of receipts you keep meaning to organise. Whether you are a freelancer, a home baker, or running a team of 20, here are 10 accounting services that can take the numbers off your plate so you can focus on actually running your business.

What should small businesses look for in an accounting service in Singapore?

Singapore makes it relatively straightforward to run a business, but the compliance requirements are real. Every company incorporated here needs to file annual returns with ACRA, submit tax returns to IRAS, and maintain proper accounting records. If your revenue crosses S$1 million, you will also need to register for GST.

For most small businesses, the key things to look for in an accounting service are: monthly bookkeeping (so you are not scrambling at year-end), tax filing, and corporate secretarial support. Prices in Singapore typically range from $100 to $400 per month for basic bookkeeping, with annual tax filing packages starting from $400 to $800. If you need a full suite including payroll, GST filing, and corporate secretary, expect to pay $300 to $800 per month depending on your transaction volume.

Cloud-based services have become the norm. If your accountant is still asking you to drop off a folder of paper receipts, it might be time to upgrade.

Which are the best affordable accounting services for freelancers and solopreneurs?

1. Osome

Price: From $112/month for bookkeeping, corporate secretary packages from $240/year

Location: Online-first, office at Robinson Road (Tanjong Pagar MRT)

Osome has become one of the go-to choices for small businesses and solopreneurs in Singapore. Everything is managed through their app and dashboard. You snap photos of receipts, upload bank statements, and their team handles the rest. They also offer company incorporation, corporate secretary, and tax filing as bundled packages. The interface is clean and modern, and their support team is responsive on chat. If you want a no-fuss, tech-forward accounting experience, Osome is hard to beat.

2. Sleek

Price: From $100/month for bookkeeping, all-in-one packages from $299/month

Location: Online-first, office at Cecil Street (Telok Ayer MRT)

Sleek is another popular digital-first accounting platform that handles bookkeeping, tax, corporate secretary, and even payroll. Their all-in-one package is popular with businesses that want everything under one roof. The platform integrates with Xero and automatically categorises transactions from your bank feeds. They are particularly good for e-commerce businesses and startups that have lots of small transactions. Response times are generally fast, though some users note that during peak filing season (November to January), things can slow down a bit.

3. Sprout

Price: From $80/month for basic bookkeeping, annual packages from $960/year

Location: Online with office at Aljunied

Sprout is a smaller, homegrown firm that has built a loyal following among freelancers, tuition teachers, and home-based businesses. Their pricing is competitive and they are known for being patient with business owners who are not numbers people. If you are a sole proprietor doing under $500K in revenue and just need someone to keep your books clean and file your taxes on time, Sprout is a solid, affordable choice. They also offer a one-time annual filing service if you do not need monthly bookkeeping.

4. BoardRoom

Price: From $300/month for SME packages, custom pricing for larger businesses

Location: Battery Road (Raffles Place MRT)

BoardRoom is one of Singapore's most established corporate services firms, with over 50 years of history. They handle accounting, payroll, tax advisory, and corporate secretarial for businesses ranging from startups to listed companies. For small businesses that are growing fast and need a firm that can scale with them, BoardRoom offers that peace of mind. Their team includes qualified chartered accountants who can advise on tax planning and structure. The trade-off is that they are pricier than the digital-first platforms, but you get more hands-on advisory support.

5. Rikvin

Price: Annual accounting and tax packages from $600, corporate secretary from $280/year

Location: Cecil Street (Telok Ayer MRT)

Rikvin has been around since 1998 and is well known for company incorporation and corporate services. Their accounting packages are popular with small businesses that have straightforward needs. They are especially good for businesses owned by foreigners or PRs who need help navigating employment pass and tax residency issues alongside their accounting. Rikvin also has an online portal where you can track the status of your filings and access your financial statements. Pricing is transparent, which is refreshing in an industry where some firms only reveal costs after an initial consultation.

6. Hawksford

Price: Custom pricing, typically from $400/month for SME accounting

Location: Marina Boulevard (Marina Bay MRT)

Hawksford (formerly Janus Corporate Solutions) is a mid-tier firm that sits between the budget digital platforms and the Big Four. They offer accounting, tax, payroll, and advisory services with a personal touch. Each client gets a dedicated account manager, which means you are not explaining your business from scratch every time you call. They are a good fit for businesses doing $1M to $10M in revenue that need proper financial reporting and advisory but do not need (or want to pay for) a Big Four firm.

7. Xero (with a local accountant)

Price: From $38/month for the software, plus accountant fees

Xero is the most popular cloud accounting software in Singapore for small businesses. It connects to local banks (DBS, OCBC, UOB), handles GST calculations, and generates IRAS-compliant financial statements. Many small business owners use Xero for day-to-day bookkeeping and then hand things over to an accountant for year-end filing. Most of the firms on this list (Osome, Sleek, Rikvin) integrate with Xero, so even if you start doing your own books, you can bring in help later without switching systems.

8. QuickBooks Online

Price: From $22/month (Simple Start plan)

QuickBooks is Xero's main competitor in Singapore. It is slightly cheaper at the entry level and has a reputation for being easier to learn if you have zero accounting background. The invoicing features are strong, and it handles multi-currency well if you have overseas clients. One thing to note: fewer Singapore accountants use QuickBooks compared to Xero, so if you plan to hand off to a local firm later, check that they support it first.

Which are the best niche accounting services for specific business types?

9. Lanturn

Price: Incorporation and accounting bundles from $500/year, monthly plans from $150/month

Location: Online-first, office at One Raffles Place

Lanturn is built specifically for startups and small businesses in Singapore. Beyond accounting, they offer grant advisory (helping you apply for government grants like the Enterprise Development Grant), fundraising support, and business structuring advice. If you are a startup founder who needs an accountant that understands cap tables, convertible notes, and ESOP schemes, Lanturn speaks your language. Their platform is modern, and the team skews young and startup-savvy.

10. Ace Tax Services

Price: From $200 for annual tax filing, monthly bookkeeping from $120/month

Location: Bukit Merah (Redhill MRT area)

Ace Tax is a neighbourhood firm that has been quietly serving hawkers, retail shops, and F&B businesses in the Bukit Merah and Tiong Bahru area for over 15 years. They understand the unique needs of cash-heavy businesses, including POS integration, daily sales reconciliation, and GST for food services. If you run a kopitiam, a nail salon, or a neighbourhood retail shop and want an accountant who gets your business without you having to explain what "cash float" means, Ace Tax is worth a call. They are old-school in the best way: reliable, thorough, and personally involved.

How much does accounting cost for a small business in Singapore in 2026?

Here is a rough guide based on business size:

• Sole proprietors and freelancers: $80 to $200/month for bookkeeping, $200 to $500 for annual tax filing
• Small Pte Ltd (under $500K revenue): $150 to $350/month for bookkeeping, $500 to $1,000 for annual filing and tax
• Growing SMEs ($500K to $5M revenue): $300 to $800/month for full accounting, tax, and payroll
• Corporate secretary: $200 to $500/year (required for all Pte Ltd companies)
• GST registration and quarterly filing: $300 to $600 per quarter

Many firms offer annual packages that bundle everything together at a discount. Always ask what is included and what costs extra. Common extras that catch people off guard: ad-hoc advisory calls, bank account opening support, and amendments to filed returns.

What are the key tax deadlines for Singapore businesses in 2026?

• 15 March: Deadline for filing Estimated Chargeable Income (ECI) for companies with December year-end
• 15 April: Personal income tax filing deadline (Form B1 for sole proprietors)
• 30 November: Corporate tax return (Form C-S or Form C) deadline
• Quarterly: GST returns due one month after each quarter ends
• Within 30 days: Annual return filing with ACRA after your AGM

Missing these deadlines can result in penalties starting from $200 and going up to $1,000 or more. A good accountant will send you reminders well in advance and handle the filings on your behalf.

Any tips for choosing the right accounting service in Singapore?

• Match the service to your stage. A freelancer doing $50K a year does not need the same firm as a startup raising Series A. Do not overpay for services you will not use.
• Ask about response times. Some firms are great at filing but terrible at answering ad-hoc questions. If you need quick advice during the year, make sure that is part of the package.
• Check if they handle GST. If you are approaching the $1M threshold, you want a firm that can advise on voluntary vs mandatory registration and handle quarterly filings.
• Look for transparent pricing. If a firm will not give you a clear quote without a "consultation call", that is usually a sign that the final bill will be higher than expected.
• Read Google reviews, but focus on the recent ones. Accounting firms can change a lot in 2 to 3 years as staff turn over. What mattered in 2023 might not reflect the 2026 experience.
