Short answer: You can pick any date as your FYE. Your first financial year can run for up to 18 months without ACRA approval. After that, each financial year is normally 12 months. The FYE sets the deadlines for your AGM, annual return, Estimated Chargeable Income (ECI) and tax return. It also decides which Year of Assessment (YA) your profits fall into. For a start-up, a badly chosen first FYE can use up one of the three years of the start-up tax exemption on a short stub period. You can change the FYE later on Bizfile, but there are limits.
What does your financial year end drive?
The FYE is the last day of your company's accounting period. You declare it when you incorporate on Bizfile. ACRA reminds companies to choose it carefully because almost every compliance deadline runs from it:
| Obligation | Deadline (non-listed company) | Regulator |
|---|---|---|
| File Estimated Chargeable Income (ECI) | Within 3 months after FYE (unless exempt) | IRAS |
| Send financial statements to members, if the company is exempt from holding an AGM | Within 5 months after FYE | ACRA |
| Hold the AGM (if required) | Within 6 months after FYE | ACRA |
| File the annual return | Within 7 months after FYE | ACRA |
| File Form C-S / C-S (Lite) / C | 30 November of the Year of Assessment | IRAS |
Listed companies have shorter deadlines: the AGM is due within 4 months and the annual return within 5 months. A company with a share capital that keeps a branch register outside Singapore gets one extra month to file its annual return. No ECI filing is needed if annual revenue is S$5 million or less and the ECI is nil.
Your FYE also decides when your auditor does the work (if you need an audit), when your books must be closed, and how your reporting lines up with any parent company or investor.
The rules for your first financial year
- Any date works. ACRA says you can choose any date as your FYE, and accounting periods can be 12 months or 52 weeks.
- The first financial year can be up to 18 months. Under section 198 of the Companies Act 1967, a company's first financial year must not be longer than 18 months unless the Registrar approves. This lets a company incorporated mid-year run its first accounts to a convenient date, such as the following 31 December.
- Later financial years are 12 months, unless you change the FYE (see below).
A longer first period means one set of accounts and, if needed, one audit instead of two. For a small start-up that is a real cost saving. The trade-off is on the tax side.
How your FYE maps to IRAS Years of Assessment
Singapore taxes companies on a preceding-year basis. The basis period for a Year of Assessment is the financial year ending in the year before the YA. Profits for the year ending 31 December 2026 are taxed in YA 2027. Profits for the year ending 31 March 2027 are taxed in YA 2028.
IRAS says a YA generally should not cover more than 12 months. So when a new company's first accounts run for more than 12 months, IRAS splits the profit across two YAs. Income is attributed to each period on an actual basis, or apportioned by days if that is not possible. IRAS's own example:
The start-up tax exemption trap
A qualifying new company gets the start-up tax exemption for each of its first three consecutive YAs. It is a 75% exemption on the first S$100,000 of normal chargeable income and 50% on the next S$100,000. The company must be incorporated and tax resident in Singapore and meet IRAS's shareholding conditions. Investment-holding companies and property developers are excluded and get the smaller partial tax exemption instead.
Here is the trap. The three YAs are consecutive and start with your first YA. Even a very short stub period counts as one of the three. If your first YA covers only a month or two of start-up costs and little or no profit, you have used a third of the exemption on a period with no tax to save. Fewer exempt years are then left for when the business is actually profitable.
Example. A company is incorporated on 1 March 2026 and expects to become profitable in its second year.
- FYE 31 March 2027 (13-month first period): YA 2027 covers just 1–31 March 2026. Exempt years are YA 2027, 2028 and 2029, and one of them is spent on a one-month stub.
- FYE 31 December 2026 (10-month first period): YA 2027 covers 1 March – 31 December 2026, a meaningful period. The exempt years are again YA 2027, 2028 and 2029, but each covers a fuller trading period.
- FYE 28 February 2027 (12-month first period): YA 2028 is the first YA, covering a full first year. The exempt years then run YA 2028, 2029 and 2030, about one year later into the growth curve.
Which option is best depends on when you expect profits to arrive. Model it before you incorporate, not after.
Five factors to weigh when choosing
- Group alignment. If you are a Singapore subsidiary of an overseas group, matching the parent's FYE makes consolidation, transfer pricing documentation and group audits far simpler. Many Japanese and Indian groups use 31 March, and Australian groups often use 30 June.
- Your business cycle. Close the year in a quiet month, after peak season, when inventory and receivables are lowest and easiest to count and confirm.
- Audit-firm availability. Most Singapore companies use 31 December, so January to June is peak season for auditors and accountants. A March, June or September year end can mean faster turnaround and more attention from your audit team.
- Tax timing. Your FYE decides which YA profits fall into and how long you have before the 30 November filing date. A 30 June or 31 March year end leaves about 17 or 20 months between the FYE and the Form C due date. A 31 December year end leaves 11 months. (ECI is still due within three months, so tax estimates come early whatever you choose.) Factor in the start-up exemption point above.
- Investor and lender reporting. Funds and banks may want accounts on a calendar-year basis or in line with their own reporting. Ask before you lock in.
Worked example: December vs March vs June
Here are the key deadlines for a non-listed private company that is exempt from holding an AGM:
| FYE 31 Dec 2026 | FYE 31 Mar 2027 | FYE 30 Jun 2027 | |
|---|---|---|---|
| ECI due (if not exempt) | 31 Mar 2027 | 30 Jun 2027 | 30 Sep 2027 |
| Financial statements to members | 31 May 2027 | 31 Aug 2027 | 30 Nov 2027 |
| AGM, if one is held or requested | 30 Jun 2027 | 30 Sep 2027 | 31 Dec 2027 |
| Annual return | 31 Jul 2027 | 31 Oct 2027 | 31 Jan 2028 |
| Year of Assessment | YA 2027 | YA 2028 | YA 2028 |
| Form C-S / C due | 30 Nov 2027 | 30 Nov 2028 | 30 Nov 2028 |
A December year end is the most familiar choice but has the tightest tax timetable and the busiest audit season. March and June year ends spread the workload and give more time before the tax return is due.
How to change your financial year end
You can change your FYE through the Bizfile transaction to update the financial year end date. Directors normally approve the change by resolution first. ACRA's rules:
- You must notify ACRA of any change, giving the revised FYE and financial year period. The filing is free.
- ACRA approval is needed if the new financial year would be longer than 18 months, or if you changed your FYE on or after 31 August 2018 and want to change it again within five years. You must upload a supporting document explaining why. Approval can take up to 14 working days. Otherwise the change takes effect immediately.
- You can only change your current or previous financial year.
- You cannot change your FYE once you have missed your AGM, annual return or financial statements deadlines. Changing the FYE is not a way to fix a late filing.
The tax side. IRAS has said there is no need to inform it separately, because it updates its records from information filed with ACRA. However, a change creates a short or long accounting period. That can move profits between YAs, or bring two sets of results into one YA. Work out the basis periods with your tax adviser before you file the change.
Your deadlines move with the new FYE. AGM, annual return and ECI deadlines run from the new date, so update your compliance calendar the same day.
Decision checklist
- Does a parent company, investor or lender need a particular year end?
- When is your quietest month for stock counts and closing the books?
- Will you need an audit, and when will your auditor have capacity?
- When do you expect your first taxable profits, and how does the first FYE fall against the three start-up exemption years?
- If your first period is over 12 months, have you mapped how the profit splits across YAs?
- Have you put the ECI, AGM, annual return and Form C dates for your chosen FYE into a compliance calendar?
- If you're changing an existing FYE, are all past AGM, annual return and financial statements deadlines met? Have you changed it in the last five years?
Frequently asked questions
Can I choose any date as my company's financial year end?
Yes. ACRA lets you choose any date, and accounting periods can be 12 months or 52 weeks. You declare the FYE at incorporation on Bizfile.
How long can my first financial year be?
Up to 18 months from incorporation without ACRA approval (section 198, Companies Act 1967). After that, financial years are normally 12 months.
Can I change my financial year end later?
Yes, through Bizfile, free of charge. ACRA approval is needed if the new financial year would exceed 18 months or if you want to change again within five years of a change made on or after 31 August 2018. You cannot change it after missing your AGM, annual return or financial statements deadlines.
Do I need to tell IRAS if I change my FYE?
IRAS has said it updates its records from ACRA filings, so no separate notice is needed. The change can still affect which YA your income falls into, so plan the tax effect first.
Is 31 December the best financial year end?
Not automatically. It is the most common choice and is convenient for calendar-year reporting. But it falls in auditors' busiest season and gives the shortest gap before the tax return. Group alignment, your business cycle and when you expect profits matter more.
The bottom line
Picking a financial year end takes thirty seconds on the incorporation form, and it shapes your compliance calendar for years. A few minutes of planning on group alignment, audit timing and the start-up tax exemption can save real tax and a lot of year-end stress. If you already have an FYE that doesn't fit, it can usually be changed, but check the five-year rule and the tax effect first.
