Your company is registered. Does it still have to file anything if it has no customers yet? Who tells you when a deadline is coming? And what happens if you miss one?
Singapore company compliance is the set of yearly filings, tax returns and record-keeping duties that every registered company must meet, whether or not it earns revenue. Two agencies set the rules; the Accounting and Corporate Regulatory Authority (ACRA) registers and regulates companies while the Inland Revenue Authority of Singapore serves as the country’s tax authority (IRAS).
This guide is part two of ATHR's series for new founders. Part one showed how to register a company. This guide covers what comes next: the compliance calendar, tax filings, company records, 2026 rule changes and penalties. It is written for first-time founders and for foreign founders who run a Singapore company from abroad.
Key Takeaways
The table summarises the facts most new founders need first.

Nearly every obligation in this guide applies to every Singapore company, whether or not it earns revenue. The amount of work changes with what your company does, but even a dormant company still files an annual return with ACRA.
The table shows where most new founders sit.
In every row, the annual return is still due. IRAS also states that a dormant company must file its tax return unless it has been granted a waiver.
Imagine Maria, a founder in Manila, who registers a company in March 2026 with a 31 December year end and makes no sales in year one. Her first financial year ends on 31 December 2026. She still files the annual return by 31 July 2027 and the tax return by 30 November 2027.
Company compliance in Singapore means meeting the recurring filing, tax and record-keeping duties the law places on every registered company and its directors. ACRA handles corporate filings such as the annual return. IRAS handles tax. Both agencies count their deadlines from your financial year end.
Your financial year end (FYE) is the last day of your company's accounting year. You chose it when you registered, and it sets almost every deadline in this guide. Part one explains how to choose it.
You file with ACRA through Bizfile+, ACRA's online portal. Corppass is the digital login a company uses to deal with government agencies. Directors stay responsible even when someone else files for them, and ACRA's guidance on directors' duties applies to all directors, including nominee directors.

Your company runs on two clocks. The first starts on your incorporation date and covers one-off appointments. The second starts on your financial year end and repeats every year.
The table lists what falls due in your first year, in order.
The appointments come from ACRA's guidance on directors and company secretaries. ATHR's first-year compliance timeline walks through the opening months.
After your first year closes, four deadlines repeat. As of October 2026, a company with a 31 December 2025 year end has one left this year: the tax return on 30 November.
The tax return follows a different rule. IRAS sets one due date of 30 November for Form C-S, Form C-S (Lite) and Form C, whatever your year end.
Your financial year end is harder to change than it looks. ACRA does not allow a change after you have missed the AGM, annual return or financial statement deadlines. It also needs ACRA's approval if the new period runs beyond 18 months or you changed your year end in the past five years.
Treat the date you chose at registration as fixed.
Every company files an annual return with ACRA each year. Most also hold an AGM and file financial statements, and many small companies are exempt from an audit. ACRA's requirements follow a set order: prepare accounts, hold the AGM, file the annual return and file the financial statements.
Yes, unless an exemption applies. A private company must hold its AGM within 6 months after its financial year end. It can skip the AGM in three cases: sending financial statements to all members within 5 months of year end, being dormant with total assets of S$500,000 or less, or all members agreeing to dispense with AGMs.
ACRA's AGM page lists these routes and allows you to apply for an extension before the deadline. ATHR's AGM guide explains each in practice.
An exemption does not remove the paperwork. When you file your annual return, ACRA requires you to declare your AGM status: held, exempt or dispensed with.
Decide which route you are using before you open the filing.
All companies registered in Singapore must file an annual return each year, even if inactive or dormant. The deadline is 7 months after year end, or 8 months if the company keeps a branch register outside Singapore. The fee is S$60, and an extension of time costs S$200.
The annual return does not replace your tax filing with IRAS, as ACRA's deadline page confirms.
Most companies must file their financial statements with ACRA in XBRL format, with limited exceptions. XBRL is a digital tagging format that lets ACRA read each figure automatically, and your accountant normally prepares it.
Plain-English: XBRL means your accounts are submitted as structured data, not only as a PDF.
ACRA's rules vary by company type. Smaller companies, with revenue and total assets both at S$500,000 or less, file a simplified version plus a PDF. Qualifying dormant companies are exempt. Solvent exempt private companies may choose whether to file. ATHR's XBRL guide covers software and common errors.
Not always. A private company is exempt from audit if it meets at least 2 of 3 thresholds for two consecutive financial years: revenue of S$10 million or less, total assets of S$10 million or less, and 50 or fewer full-time employees. A company under two years old needs to meet them only in its current year.
Companies in a group must also meet the thresholds as a group. Imagine a software company with S$400,000 in revenue, S$150,000 in assets and four employees. It needs no audit, but it still prepares and files financial statements.
ACRA's audit exemption page, last updated on 3 February 2026, shows the thresholds unchanged. ATHR's audit exemption guide covers the shareholder override.
IRAS needs two things from most companies each year: an estimate of taxable profit, called ECI, within 3 months of year end, and the tax return by 30 November. Both are separate from your ACRA filings, and a company that is behind on one can be on time on the other.
Estimated Chargeable Income (ECI) is your company's estimate of its taxable profit for the financial year. Companies must file it within 3 months of their financial year end. You do not need to file it if annual revenue is S$5 million or below and your ECI is nil.
IRAS states the 3-month deadline on its ECI page, and its filing guidance sets out the waiver. Both conditions must be met. ATHR's ECI filing guide covers the calculation.
Most small companies file Form C-S or Form C-S (Lite). IRAS sets these thresholds:
The simplified forms are for Singapore-incorporated companies with only standard-rate income and no claims for certain reliefs. IRAS gives the corporate income tax rate as 17%. Rebates and exemptions change by year, so check IRAS's current list before assuming one applies.
Watch out: The ECI waiver only removes the ECI filing. The tax return is still due on 30 November.
You must register for Goods and Services Tax (GST) once your taxable turnover exceeds S$1 million. IRAS assesses this over each calendar year, and you must apply within 30 days of the year end. If you register late, your liability is backdated to the date you should have registered.
You owe GST on that period even if you never charged it to customers, as IRAS explains.
Part one covered how to set up your records. This section covers keeping them accurate between filings.
You must tell ACRA about changes within 14 days through Bizfile+. This covers company details such as your name and registered office address, officer details such as appointments and address changes, and share and shareholder changes. ACRA's page on updating company information states that late notifications carry penalties.
Your company keeps registers of members, directors and secretaries, and a Register of Registrable Controllers (RORC), which records the people who own or control it. Nominee arrangements need their own registers. ACRA's page on company registers sets the update deadlines:
Keep accounting records for at least 5 years after each financial year ends. ATHR's guide to company registers explains what each holds.
Your registered office must be a physical Singapore address, not a P.O. box, open to the public for at least three hours on each business day. ACRA states that non-compliance can lead to a fine of up to S$5,000. ACRA also sends its communications there.
Watch out: If you are an overseas founder, make sure someone checks the mail at your registered office and passes anything urgent to the directors.
Your company secretary maintains the registers, arranges meetings and reminds directors of filing deadlines. Appointing one within 6 months is a legal requirement, and ACRA states that directors can be fined up to S$1,000 if the company does not.
Several changes took effect on 6 May 2026 and raised the stakes for directors. Fines for director breaches rose to as much as S$20,000, and a money laundering conviction now disqualifies a person from acting as a director.
ACRA announced the changes on 16 April 2026 as the commencement of key changes under the Corporate and Accounting Laws (Amendment) Act 2025. As of October 2026, these are the changes that matter most to a new company:
For directors, a missed duty now carries a higher ceiling. ATHR's guide to the May 2026 ACRA changes covers the wider governance picture.

Late filing starts small and escalates for repeated or long-running breaches. A late annual return costs S$300 within 3 months and S$600 after that. ACRA can then offer a composition, prosecute, strike the company off or disqualify directors, and IRAS can issue its own assessment for a late tax return.
The main steps, in the order they usually escalate, are:
ACRA sets out these steps on its page on late annual return penalties, and its penalty announcement confirms the S$300 and S$600 amounts. Directors can appeal using ACRA's late lodgement appeal form, with reviews usually taking about four weeks.
The late fee is set the moment you submit, and it doubles at the three-month mark. Once a return is overdue, filing sooner is cheaper.
Do not wait for perfect accounts before submitting.
If a company has stopped trading, filing every year is not the only choice. ATHR's comparison of dormant status and striking off explains each.
Assuming no revenue means no filings. Every registered company files an annual return, including inactive and dormant ones. Put the deadlines in your calendar on the day you register.
Treating the ECI waiver as a tax exemption. The waiver removes one filing, not the tax return. Read the wording carefully.
Missing the 14-day update. A new director, a changed address or a share transfer starts a 14-day clock, and late lodgement penalties apply after it. Ask whoever handles your filings to tell you when a change happens.
Leaving the accounts until the last month. The AGM is due at 6 months and the annual return at 7, and both need finished accounts. Missing receipts and unreconciled bank statements are the usual causes of delay.
Assuming a nominee director or filing agent carries your responsibility. ACRA's duties apply to all directors, including nominees. A filing agent submits documents but does not take over the legal duty to file on time.
You can manage ongoing compliance yourself, through a registered filing agent, or through a full-service provider. The right route depends on how much your company does, where your directors live and how much time you have to track deadlines.
The table compares the three routes.
Self-filing is reasonable for a simple company, and the other routes earn their cost as the company grows. ATHR's explainer on ACRA filing agents covers how they differ from corporate service providers.
Yes. Every company registered in Singapore must file an annual return each year, even if inactive or dormant. You also file a tax return by 30 November unless IRAS has granted a waiver. The ECI filing may be waived if revenue is S$5 million or below and ECI is nil.
Usually, but not always. A private company must hold its AGM within 6 months of year end. Three exemptions exist: sending financial statements to members within 5 months, being dormant with assets of S$500,000 or less, or all members agreeing to dispense with AGMs. You still declare your AGM status in the annual return.
S$300 if you file within 3 months of the deadline, and S$600 after that. ACRA applies it when you submit. Repeated breaches can lead to a composition offer, prosecution, striking off and director disqualification.
Not if it is a private company meeting at least 2 of 3 thresholds for two consecutive years. The thresholds are revenue of S$10 million or less, total assets of S$10 million or less and 50 or fewer employees. You must still file financial statements. Group companies must meet the thresholds as a group.
Not if annual revenue is S$5 million or below and your ECI is nil, because IRAS waives the filing. A loss typically gives a nil ECI, but confirm with your accountant. The waiver does not remove the tax return due on 30 November.
Sometimes. You can change it for the current or previous financial year, but not after missing the AGM, annual return or financial statement deadlines. ACRA's approval is also needed if the new period exceeds 18 months or you changed your year end in the past five years.
No. A nominee director has a director's full legal duties, and a filing agent only submits what you give it. The company and its directors remain responsible for filing correctly and on time.
If you are not sure where your company stands, start by writing down a few details. Note your financial year end, who your directors are and where they live, whether you have revenue or staff, and what you have already filed. With those, it is straightforward to see which deadlines are close and what is missing.
ATHR's corporate secretary service supports the statutory filings and compliance tracking covered in this guide. When secretarial and accounting work sit with one team, a missing document comes up before the AGM and annual return deadlines, not after them. Share your year end, your directors' locations and your filing history, and the team can explain the next steps, the documents you need and the scope of support.
