: Singapore Post-Incorporation Compliance — Every Annual Deadline Your Company Must Meet

Every Singapore Private Limited Company has annual obligations that run on a fixed cycle. Missing one does not pause the others — ACRA and IRAS both impose penalties from the first day a deadline is missed. This guide tells you exactly what is due, when, and what happens if it is late.

If you have just incorporated a Singapore company, these obligations start from your first financial year-end. Understanding your company structure matters too — a Pte Ltd has more obligations than a Sole Proprietorship or LLP.

ACRA Annual Return — What It Is and When to File

The Annual Return updates ACRA's register with your company's current information. It is not optional.

Every Singapore-incorporated company must file an Annual Return (AR) with ACRA each year. The AR confirms your company's registered address, directors, shareholders, and share capital are up to date on the public register. It does not replace your financial statements — it accompanies them.

Deadline

For private companies, the Annual Return must be filed within 7 months of your financial year-end (FYE). For listed companies, the deadline is 5 months. So if your FYE is 31 December, your Annual Return is due by 31 July the following year.

From 2026, ACRA removed the grace period for late filings. The penalty applies from the first day after the deadline — there is no buffer.

AGM Requirement

Most private companies in Singapore are exempt from holding an AGM provided they send their financial statements to all members within 5 months of the FYE. If any member requests an AGM, one must be held. For companies that do hold an AGM, the first AGM must be within 18 months of incorporation, and subsequent AGMs within 6 months of FYE.

Late Filing Penalties

ACRA imposes a composition fine at the point of filing:

• S$300 — if filed within 3 months after the due date
• S$600 — if filed more than 3 months after the due date

Repeated non-filing can result in ACRA striking off the company or initiating prosecution against directors. Terra Advisory Services files Annual Returns for all companies we manage — late filings do not happen under our watch.

Financial Statements — Preparing and Filing

Every Pte Ltd must prepare SFRS-compliant accounts. Most SMEs qualify for audit exemption.

The SFRS Requirement

Every Singapore Private Limited Company must prepare financial statements in accordance with the Singapore Financial Reporting Standards (SFRS). These statements — which include a balance sheet, profit and loss account, and notes — must be approved by the directors before they are filed with ACRA as part of the Annual Return.

Financial statements must be prepared within 5 months of your financial year-end. This is a separate deadline from the Annual Return itself. The statements must be ready first, so that they can accompany the AR filing. Our financial report compilation service covers the preparation of SFRS-compliant unaudited financial statements for SMEs.

Small Company Audit Exemption

Most Singapore SMEs qualify for audit exemption under the small company criteria. To qualify, a company must meet at least 2 of these 3 conditions for the current and preceding financial year:

• Annual revenue not more than S$10 million
• Total assets not more than S$10 million
• Fewer than 50 employees

Companies that qualify do not need a statutory audit — they prepare unaudited financial statements instead. If your company is part of a group, the group as a whole must also meet the small company criteria. Terra Advisory Services will confirm whether your company qualifies.

IRAS Tax Filing — ECI and Form C-S

Corporate tax filing has two separate deadlines. Both are mandatory for most active companies.

Filing 1 — Estimated Chargeable Income (ECI)

The ECI is an estimate of your company's taxable income for the financial year. It must be filed with IRAS within 3 months after your financial year-end. So if your FYE is 31 December, ECI is due by 31 March.

Some companies are exempt from filing ECI — those with annual revenue of S$5 million or below and a nil ECI. However, if your company has any chargeable income, ECI must be filed even if the final tax liability is small. Terra Advisory Services confirms your ECI position each year and files on your behalf through myTax Portal.

Filing 2 — Form C-S, Form C-S Lite, or Form C

The annual corporate income tax return is due by 30 November each year. The form you file depends on your company's revenue and complexity:

• Form C-S Lite — companies with annual revenue of S$200,000 or below and straightforward tax positions
• Form C-S — companies with annual revenue below S$5 million and no complex tax adjustments
• Form C — all other companies, including those with revenue above S$5 million or complex deductions

The tax return is prepared from your financial accounts. Accurate bookkeeping throughout the year makes the tax computation straightforward. For a full breakdown of exemptions, rates, and schemes like SUTE and PTE, see our Singapore tax incentives guide and corporate tax services page.

Late Tax Filing Penalties

IRAS imposes a 5% late payment surcharge on any unpaid tax from the due date. If tax remains unpaid, an additional 1% per month is charged, up to a maximum of 12 months — meaning the surcharge can reach 17% of the unpaid tax. Late filing of Form C-S can also trigger estimated assessments and enforcement action.

Other Ongoing Obligations Directors Must Not Forget

Annual filing is the headline obligation. These ongoing requirements run throughout the year.

• Update registered address within 14 days of any change. Your ACRA-registered address must be kept current at all times. Failing to update it is an offence.
• Update director and shareholder details within 14 days. Any change in directors, shareholders, or share transfers must be lodged with ACRA promptly via BizFile+. Your corporate secretary handles this.
• Maintain statutory registers. Every company must keep a register of directors, a register of members, a register of charges, and minutes of meetings. These must be available for inspection.
• Keep accounting records for at least 5 years. IRAS and ACRA can request to inspect your records. Disposing of records early is a compliance risk. Proper bookkeeping throughout the year makes this straightforward.
• File GST returns quarterly if GST-registered. If your company is registered for GST, quarterly F5 returns are due one month after each accounting period. See our GST services page for deadlines and penalties.
• Withholding tax on payments to non-residents. If your company pays service fees, royalties, or interest to overseas contractors or directors, withholding tax may apply. The deadline is one month after the date of payment.
• Renew business licences if applicable. Companies in regulated industries — food, finance, employment agencies, healthcare — must renew relevant licences on schedule. These sit outside ACRA and IRAS but carry their own penalties.
