A new Pte Ltd director asked me last month when her first filing was due. She had incorporated in March, set a 31 December financial year end, and assumed her annual obligations began from that incorporation date. They do not. The Singapore company compliance calendar is anchored to the financial year end (FYE), not to when the company was formed, and every ACRA and IRAS deadline cascades from that single reference point.
That distinction matters because the Accounting and Corporate Regulatory Authority (ACRA) and the Inland Revenue Authority of Singapore (IRAS) operate on separate but parallel timelines. Mapping your Singapore company compliance calendar across both bodies before your first financial year closes is what separates founders who breeze through their first compliance cycle from those who receive a composition notice before they have filed a single return.
Understanding your Singapore company compliance calendar
The financial year end: your master deadline trigger
Your FYE is the date from which every substantive obligation is measured. Set it deliberately. ACRA allows a company to change its FYE once without special approval, provided the new financial year does not exceed 18 months. After that, the FYE is fixed unless a formal application is made. The practical calendar for a 31 December FYE looks like this:
| Obligation | Deadline | 31 Dec FYE example |
|---|---|---|
| Annual General Meeting (AGM) | Within 6 months after FYE | By 30 June 2026 |
| Annual Return (AR) via BizFile+ | Within 7 months after FYE | By 31 July 2026 |
| Estimated Chargeable Income (ECI) | Within 3 months after FYE | By 31 March 2026 |
| Corporate Income Tax Return | 30 November each year (fixed) | 30 November 2026 |
Founders who set up a Singapore Pte Ltd as a foreign entrepreneur often choose 31 March or 31 December as their FYE because it aligns with how a home-country holding entity prepares consolidated accounts. Both work, but they produce different filing clusters. A 31 March FYE company has its ECI due 30 June, its AR due 31 October, and its tax return due the same 30 November as every other company.
ACRA vs IRAS: two clocks, one company
Both regulators use your FYE as a reference point, but they measure from it differently. ACRA’s AGM and Annual Return deadlines are expressed in months from FYE. IRAS’s ECI deadline is also FYE-relative. The corporate income tax return deadline, by contrast, is fixed: 30 November every year, regardless of when your financial year ends.
That fixed date has one practical consequence worth internalizing. A company with a 30 June FYE closes its books on 30 June, files ECI by 30 September, and files the AR by 31 January, but it still faces the same 30 November tax return deadline as the December FYE company. The two clocks converge at 30 November for every Singapore Pte Ltd, every year.
Singapore company compliance calendar: ACRA filing deadlines
AGM requirements
Under the Companies Act, a private Pte Ltd must hold its Annual General Meeting within 6 months after FYE. Listed companies face a tighter 4-month window, but the 6-month rule governs standard non-listed private companies.
The meeting must pass the resolutions that keep the company in good standing: adopting the financial statements, declaring any dividend, re-appointing directors, and confirming auditors where required. Minutes must be prepared and retained at the registered office.
Annual Return filing
The Annual Return for a non-listed Singapore Pte Ltd is due within 7 months after FYE. For companies with share capital and an overseas branch register, ACRA extends that window to 8 months, but this applies only to a narrow category of structures. For a standard Singapore-based private company, 7 months is the rule.
The AR must be filed through ACRA’s BizFile+ portal and captures the shareholding structure, director details, and charges register as at FYE. That information becomes publicly accessible on the register.
One detail founders frequently miss: the 7-month deadline runs from FYE, not from the AGM date. If the AGM is held on day 179 of the 6-month window (one day before the limit), the gap remaining to prepare and lodge the Annual Return before the 7-month mark is very short.
IRAS tax filing deadlines
Estimated Chargeable Income
The ECI is a company’s estimate of its taxable income for the financial year. IRAS requires it within 3 months from FYE. For a company with a 31 December 2025 FYE, that means 31 March 2026.
IRAS grants an automatic waiver for companies whose ECI is nil and annual revenue is S$5 million or below. If revenue exceeds that threshold, or if no specific waiver has been granted, ECI filing is mandatory regardless of profitability.
Corporate income tax returns
The corporate income tax return deadline is 30 November each year. For Year of Assessment (YA) 2026, covering financial years ending in the 2025 calendar year, that date is 30 November 2026. IRAS sends a filing notification by May each year from the second year after incorporation, but 30 November binds whether or not the notification arrives.
Which form you use depends on annual revenue:
| Form | Annual revenue | Financial statements required? |
|---|---|---|
| Form C-S (Lite) | S$200,000 or below | No |
| Form C-S | S$200,001 to S$5 million | No |
| Form C | Above S$5 million | Yes (full financials and tax computation) |
Form C-S and Form C-S (Lite) do not require submission of financial statements or a tax computation document with the return itself. IRAS may request those on review, but they are not filed upfront. Form C requires both as part of the submission package.
I’ve seen early-stage founders overlook the zero-revenue filing requirement more than any other on this list. Filing is mandatory even for loss years and zero-revenue years. There is no exemption from the 30 November deadline because the company generated no income. Dormant companies may apply to IRAS for a waiver of income tax return filing, but that waiver must be granted before the deadline; it is not assumed from dormancy alone. The enhanced corporate tax rebate for YA 2026 (50% of tax payable, capped at S$40,000 combined rebate and cash grant, announced following the April 2026 ministerial statement) is applied automatically by IRAS after filing. No separate claim is needed.
Missing deadlines: penalties and enforcement
Staying on top of your Singapore company compliance calendar is the fastest way to prevent ACRA compositions and IRAS enforcement actions from accumulating in the same filing season.
ACRA late filing
ACRA’s enforcement guidance shows a minimum composition of S$500 for Annual Return filings missed by approximately one month. The same minimum applies to a missed AGM deadline. Both are tracked separately: two missed deadlines in a single year produce two compositions.
Repeated or prolonged non-filing escalates to ACRA initiating a striking-off application. That process runs through multiple Gazette notifications and takes approximately four to six months from initiation to removal.
IRAS enforcement
IRAS treats non-filing of the corporate income tax return as an active enforcement matter. Late or non-filing results in compositions or court summons. IRAS does not publish fixed composition amounts for late returns in the same way ACRA does, but the enforcement is active regardless of company size.
For companies approaching wind-down, the picture differs from a standard strike-off. In a liquidation, the liquidator takes responsibility for the company’s tax affairs under the Income Tax Act and must make provision for any tax payable before distributing assets to shareholders. If you are navigating a Singapore company liquidation, resolving outstanding tax filings through proper channels is not optional and avoids personal exposure for the liquidator.
The substance requirements IRAS applies when assessing whether a company qualifies as Singapore tax resident also affect access to resident-conditioned reliefs. A company that lacks control-and-management exercised in Singapore may still have filing obligations but cannot access the Start-Up Tax Exemption (SUTE) or other exemptions reserved for Singapore tax residents.
FAQ
What are the main annual compliance deadlines for a Singapore Pte Ltd company?
A Singapore Pte Ltd has four primary annual deadlines. The AGM must be held within 6 months of FYE. The Annual Return must be filed with ACRA within 7 months of FYE. ECI must be submitted to IRAS within 3 months of FYE. The corporate income tax return is due on 30 November each year, regardless of when the company’s financial year ends.
When is the Annual Return due if my financial year end is 31 December?
For a 31 December FYE, the Annual Return is due by 31 July of the following year and the AGM must be held by 30 June. For FY2025 (ending 31 December 2025), both deadlines fall in the first half of 2026.
What happens if I miss the AGM, Annual Return, or tax filing deadline?
Missing the Annual Return deadline by approximately one month draws a minimum S$500 composition from ACRA. The same minimum applies to a missed AGM. Both obligations are tracked separately, so two missed deadlines in a single year produce two compositions. IRAS enforces late corporate income tax returns through compositions or court summons. Prolonged non-filing with ACRA triggers a striking-off process that is materially more costly to reverse than addressing the filing on time. Proactive contact with both regulators before a deadline passes, explaining the delay, is the standard approach where a return cannot be submitted in time.
Do I need to file a corporate income tax return if my company made no profit?
Yes. IRAS requires the annual corporate income tax return from every company, including those that incurred a loss or had zero revenue for the year. Dormant companies may apply separately for a waiver of this obligation, but IRAS must grant that waiver before 30 November; it is not automatic. A nil return filed on time is far less disruptive than an IRAS enforcement notice.
