Annual Compliance Calendar for Singapore Companies

Running a company in Singapore involves more than just day-to-day operations. Directors are responsible for ensuring the company complies with statutory filing requirements under the Companies Act, ACRA regulations and IRAS tax rules.

This article summarises the key recurring deadlines that Singapore companies should track each year, and highlights the main documents that directors are expected to review, approve or sign.

1. Annual General Meeting (AGM)

For most companies, the AGM is the formal meeting where the financial statements are laid before shareholders, and where certain ordinary business (e.g. approval of accounts, directors’ fees, re-appointment of auditors) is transacted.

In many cases, private companies can choose to dispense with AGM if conditions are met and proper procedures are followed. If AGMs are held, typical timelines to consider are:

• Financial statements must be prepared and approved by the board before they are presented at the AGM.
• Notices of AGM need to be sent in accordance with the company’s constitution.

At the AGM (or via written resolutions, if AGM is dispensed with), directors should ensure that:

• The financial statements and directors’ statement are properly approved.
• Any dividends, directors’ fees or other matters requiring shareholder approval are clearly documented.

2. ACRA Annual Return (AR)

Every Singapore-incorporated company must file an Annual Return with ACRA. The AR provides key information about the company, including:

• registered office address
• principal activities
• particulars of directors, company secretary and shareholders
• financial statements (or key financial highlights, where applicable)

The Annual Return is typically due within a prescribed period after the AGM or after the FYE, depending on the company’s circumstances and whether it is a listed or non-listed company.

Before filing the AR, directors should ensure:

• The latest financial statements have been properly approved by the board.
• Company particulars are up to date (changes in officers, share capital, address, etc.).
• Any required resolutions (e.g. appointment of company secretary, auditor) have been appropriately recorded.

Often, the AR is filed by the company secretary or corporate services provider, but directors remain ultimately responsible for its accuracy and timeliness.

3. Estimated Chargeable Income (ECI) – IRAS

The Estimated Chargeable Income (ECI) is an estimate of the company’s taxable profits for a given Year of Assessment (YA). Companies are generally required to file their ECI within a few months after the financial year end, subject to IRAS rules and filing waivers for certain small companies.

Key points for directors:

• ECI is based on management accounts or draft financial results; it does not require a finalised set of audited accounts.
• Early filing may allow the company to benefit from longer GIRO instalment plans for tax payment.
• Even if the final tax computation will be refined later, directors should ensure the estimate is reasonable and supportable.

Finance teams or external accountants typically prepare the ECI figures, but directors should understand the assumptions, especially where there are large one-off items or significant changes from prior years.

4. Corporate Income Tax Return – Form C-S / Form C

Each year, companies must file their corporate income tax return with IRAS, usually via:

• Form C-S / C-S (Lite) – simplified return for qualifying small companies; or
• Form C – full version for companies that do not qualify for Form C-S.

The return covers the Year of Assessment, which is based on the company’s accounting year (e.g. FYE 31 December 2024 ? YA 2025).

Key steps involved:

• Preparation of tax computation and schedules
• Review of adjustments from accounting profit to taxable income
• Confirmation of capital allowances, loss carry-forwards and incentives
• Completing the Form C-S/C contents (usually via myTax Portal)

Directors should:

• Review the final tax computation and understand key adjustments.
• Ensure significant tax positions (e.g. group charges, related-party transactions, incentives) are properly documented.
• Approve the submission or authorise the tax agent to file on behalf of the company.

5. GST Returns (if applicable)

If the company is GST-registered, it must file periodic GST returns (commonly quarterly, but some companies may be on monthly or half-yearly cycles).

Each GST return requires:

• Reporting of output tax (GST collected on sales)
• Reporting of input tax (GST paid on eligible purchases)
• Ensuring proper tax invoices, import permits and supporting documents are retained

Key considerations for directors:

• Ensure there is a clear cut-off process at each GST period end.
• Review exceptions – such as disallowed input tax, non-business expenses or exempt supplies.
• Confirm that GST is properly configured in the accounting system and reconciled to the general ledger.

For many SMEs, GST errors are a common focus area in IRAS audits and reviews, so having a simple internal review checklist each quarter is advisable.

6. Other recurring compliance items

Depending on the nature of the company, directors may also need to monitor:

Changes in officers and particulars

• Appointment or resignation of directors, auditors, company secretary
• Changes in nationality, identification number or residential address
• These changes often require timely filings with ACRA.

Share capital changes

• New share issues, transfers, redemptions or buy-backs
• Resolutions and ACRA filings relating to share capital and ownership structure

Licences and regulatory filings

• Sector-specific licences (e.g. for financial services, charities, fund-raising, regulated trades)
• Grant reporting and compliance documentation

These may not follow a fixed annual calendar but should be incorporated into the company’s internal compliance checklist.

7. Documents directors typically review and approve

Throughout the year, directors are expected to review, approve or sign off on key documents, including:

• Board resolutions approving financial statements and directors’ statements
• AGM documentation and shareholder resolutions (or written resolutions in lieu of AGM)
• ACRA filings prepared by the company secretary (e.g. AR, changes in officers, share capital)
• Tax computations, ECI and Form C-S/C submissions
• Supporting schedules for major decisions (e.g. dividends, director’s fees, significant provisions or write-offs)

Good practice includes:

• Keeping minutes and resolutions properly documented and filed
• Ensuring decisions are made on an informed basis, with sufficient explanation from management or advisors
• Reviewing draft documents early enough to allow for questions and revisions

8. Building a simple compliance calendar

To stay on top of obligations, many companies find it useful to maintain a compliance calendar that tracks:

• Key dates based on the financial year end
• Responsible parties (e.g. internal finance, company secretary, tax agent)
• Lead time for preparation and review (e.g. draft accounts 1–2 months before filing deadlines)
• Reminders for GST periods, licence renewals and grant reporting

This can be as simple as an Excel sheet, shared calendar, or a practice management tool—so long as it is maintained and reviewed regularly.
