Singapore Accounting and Bookkeeping Services: Compare Providers and Pricing (2026)

Most Singapore compliance deadlines are anchored to your financial year-end (FYE), not the calendar year, so the calendar below is expressed relative to your FYE. Each deadline links to a step-by-step guide.

Within 3 months of FYE, file your ECI

Your Estimated Chargeable Income is due within three months of your financial year-end, unless you qualify for the filing waiver. Filing early through GIRO also gives you more instalments to spread the tax. The full waiver test and instalment ladder are in our Singapore ECI filing guide.

Anytime, watch the GST registration trigger

GST registration becomes compulsory once your taxable turnover crosses S$1 million, under either a retrospective or a prospective test, with a two-month grace period for prospective registrations since 1 July 2025. The thresholds and the myTax Portal application are covered in our Singapore GST registration guide.

By 30 November, file your corporate tax return

Every company files Form C, Form C-S, or Form C-S (Lite) by 30 November, even if dormant or loss-making, unless granted a waiver. Which form you use depends on revenue and complexity; see our Singapore corporate tax filing guide.

Within 7 months of FYE, file your annual return and XBRL

Non-listed companies file their annual return within seven months of FYE (five months if listed), with financial statements in XBRL where required. Choosing the right XBRL template is the part that trips people up; our Singapore XBRL filing guide walks through it.

Each year, confirm your audit position

A private company that qualifies as a small company is exempt from the statutory audit, but the exemption is dynamic and the group test catches foreign-owned subsidiaries. The criteria are in our Singapore small company audit exemption guide.

Where to file

You file your corporate tax return and ECI on the IRAS myTax Portal, and your annual return with XBRL through ACRA BizFile+. The primary references are the IRAS ECI page, the IRAS Form C filing guidance, the ACRA XBRL requirements page, and the ACRA audit exemptions page.

Indicative market ranges based on published 2026 pricing from Singapore accounting providers, verified 8 June 2026. Accounting fees are private market prices, not regulated rates, and vary by transaction volume and provider. For specific, dated quotes per provider, use the comparison table above.

Basic bookkeeping, from S$60 to S$300 per month

Transaction recording, bank reconciliation, and basic financial statements. Best for dormant companies and sole proprietors with low volume.

Bookkeeping plus annual filing, from S$200 to S$500 per month

Bookkeeping plus Form C-S or C-S (Lite), ECI, and the annual return. Best for active SMEs not registered for GST.

GST-registered SME, from S$400 to S$1,000 per month

The above, plus quarterly GST returns and management reports. Best for companies above S$1 million turnover, or voluntarily GST-registered.

Full compliance with audit support, from S$1,000 to S$3,000 or more per month

The above, plus audit coordination, advisory, and Full XBRL. Best for companies above the S$10 million audit exemption threshold.

Fractional CFO and advisory, quote-based

Strategic advisory, cash-flow forecasting, board reporting. Best for growth-stage SMEs and funded startups. Pricing is quote-based and commonly several thousand per month.

These are indicative ranges to help you budget, not quotes. The tier you need is driven mostly by your transaction volume, whether you are GST-registered, and whether you have crossed the audit exemption threshold. For provider-specific, dated pricing, use the comparison table above.

The tier you fall into is easier to see through a profile. The four below cover most non-resident-founded Singapore companies. Ranges are indicative 2026 market figures, verified 8 June 2026.

Profile 1, Solo founder, dormant or very low-activity Pte Ltd

Low transaction volume, not GST-registered, no employees. You usually need compliance only: financial statement preparation, the annual return, and the corporate tax return. A dormant company can file the simpler Form for Dormant Company. Indicative outsourced cost is from S$60 to S$150 per month, and if your company's revenue is S$200,000 or below its return is likely Form C-S (Lite). A sole proprietorship is taxed differently, through the owner's personal income tax rather than the corporate return, so this profile assumes a private limited company.

Profile 2, Micro SME, revenue below S$500,000

One to fifty transactions a month, not GST-registered, perhaps a couple of contractors. You typically need monthly or quarterly bookkeeping plus annual filing. Indicative cost is from S$150 to S$400 per month. At this size your financial statements may qualify for Simplified XBRL, which applies when both revenue and total assets are S$500,000 or below, so check your asset position as well as revenue.

Profile 3, GST-registered SME, revenue S$1 million to S$5 million

Higher transaction volume, GST-registered with quarterly returns, a small team. You need regular bookkeeping, GST returns, and management reporting. Indicative cost is from S$400 to S$1,000 per month. You likely still file Form C-S and, on revenue alone, may still sit within the audit exemption threshold.

Profile 4, Employer SME with an audit obligation, revenue S$10 million or more

High volume, GST-registered, ten to fifty or more employees, and likely outside audit exemption. You need full-service accounting plus audit coordination. Indicative cost is from S$1,500 per month and up, depending on complexity, with statutory audit fees billed separately and varying by firm. A fractional CFO arrangement is quote-based and typically adds a further few thousand per month.

If you are still at the formation stage and budgeting the whole setup, our Singapore company formation cost guide breaks down the one-off costs that sit alongside these ongoing fees.

Who maintains this guide

This guide is maintained by the GrowAcross Editorial Team, an independent team that researches business expansion across Singapore, Hong Kong, and the UAE. We do not hold professional accounting credentials and we do not provide accounting advice. What we do is research provider offerings, verify regulatory facts against primary sources, and publish what we find. For decisions specific to your company, engage a Singapore-qualified accountant or a Chartered Accountant of Singapore.

Our four-step vetting process

1. Provider shortlist, built from Ahrefs SERP analysis on the main Singapore accounting commercial queries, cross-checked against the Xero advisor directory and other public listings.
2. Pricing verification, by visiting each provider's public pricing page during our research. Where pricing is not published, we mark it as quote-based and exclude it from price-based rankings.
3. Trustpilot score check at the time of review. Providers with fewer than 50 reviews are flagged as low-confidence. Trustpilot is the only third-party review source we surface.
4. Regulatory accuracy check, where every ACRA, IRAS, MOM, and MAS fact is verified against its primary source URL. Stale facts are corrected at our quarterly refresh.

How we handle commercial relationships

GrowAcross does not currently have affiliate relationships with the accounting providers compared in this guide. If we add one in the future, we will mark it explicitly on the provider card with a sponsored disclosure. Editorial rankings on accuracy, value, and support are independent of any commercial relationship.
