Post-Incorporation Checklist: What to Do After Your Singapore Company Receives Its UEN

Incorporation was the easy part#

ACRA can approve a straightforward private limited company in a day. What that approval produces — your Unique Entity Number — is not a finish line but a start signal, and a working post-incorporation checklist for Singapore is what separates founders who spend their first year building from founders who spend it retrofitting compliance.

The stakes changed in January 2026. ACRA removed the front-end grace period for statutory filings — the informal buffer under which companies that filed by the end of the due month were left alone. That buffer is gone. Penalties are triggered the moment your due date passes, at S$300 for a breach up to three months late and S$600 beyond that, applied separately to each obligation. A company that misses both its AGM and its annual return has committed two breaches, not one.

Nothing on this list is difficult. Almost all of it is cheap if done in sequence and disproportionately expensive if done late. Work through it in order.

The four clocks that started when you incorporated#

Most founders think of compliance as one annual event. It is four independent cycles, anchored to different dates and enforced by different agencies.

The critical implication: your financial year end drives three of these five deadlines. Choosing it is the single highest-leverage decision on this page, and it is covered below.

Phase 1 — Your first 30 days#

☐ 1. Set up your Register of Registrable Controllers. Every company must maintain a RORC identifying the individuals who ultimately own or control it, and lodge that information with ACRA's central register. Set it up within 30 days of incorporation. Once running, any change to the particulars must be filed with ACRA within two business days — a short window that catches founders who treat the register as an annual task.

☐ 2. Lodge nominee director and nominee shareholder particulars. If you use a nominee resident director to meet the residency requirement — as most foreign founders do — the company must maintain a Register of Nominee Directors and, where relevant, a Register of Nominee Shareholders, and submit the particulars to ACRA's central registers. The Companies and Limited Liability Partnerships (Miscellaneous Amendments) Act 2024 strengthened this regime with most provisions commencing from April 2026, so a nominee arrangement set up on older guidance may not be compliant as filed. Confirm with your provider that the central register submissions are done, not just the internal register.

☐ 3. Appoint your company secretary. Mandatory within six months of incorporation, and the secretary must be ordinarily resident in Singapore. Do not use the full six months. The secretary maintains your statutory registers and drives your filing calendar; leaving the seat empty for half a year means nobody is watching the deadlines you are now personally liable for.

☐ 4. Register your Corppass administrator. Corppass is the gateway to nearly every government digital service — IRAS myTax Portal, CPF, MOM's work pass systems, the Business Grants Portal, ACRA BizFile. Nothing else on this list can be filed until it exists. Founders routinely discover this on the day of their first deadline. Appoint an administrator within your own team, not only at your provider, so you retain access if you change firms.

☐ 5. Issue share certificates and open your statutory registers. Registers of members, directors, secretaries and controllers, plus share certificates for each shareholder. Unglamorous, and the first thing a bank, an acquirer or a due-diligence lawyer will ask to see.

☐ 6. Choose your financial year end deliberately. ACRA does not mandate a date. Your only constraint is that the first financial period cannot exceed 18 months from incorporation. This is a genuine planning lever: a longer first period defers your first ECI, AGM, annual return and tax filing, giving a company incorporated mid-year a longer runway before its first full compliance cycle. It also concentrates more trading into a single Year of Assessment, which interacts with the Start-Up Tax Exemption. Model it before you pick a date — changing FYE later requires ACRA notification and, in some cases, approval.

☐ 7. Start your corporate bank account application. Consistently the longest lead time on this list, and the item most likely to stall. Incorporation does not require an account, but you cannot trade without one. Start now, and expect two to six weeks at a traditional bank. See our guide to opening a corporate bank account in Singapore.

☐ 8. Set up bookkeeping from transaction one. Every downstream filing — ECI, financial statements, Form C-S, GST returns — is a derivative of your ledger. Reconstructing nine months of transactions from bank statements in March is the most common self-inflicted cost in a Singapore company's first year.

Phase 2 — Your first 90 days#

☐ 9. Decide your GST position. Registration becomes compulsory when taxable turnover exceeds S$1 million, tested two ways. The retrospective test looks at the past calendar year: if you exceeded S$1 million, you apply between 1 and 30 January and are registered from 1 March. The prospective test applies the moment you have reasonable grounds to expect you will exceed S$1 million in the next 12 months — you then have 30 days to apply. Late registration can be backdated by IRAS, leaving you liable for GST you never charged your customers, plus a fine of up to S$10,000 and a penalty of 10% of the GST due.

☐ 10. Register for CPF and set up payroll — if applicable. CPF contributions are required for employees who are Singapore Citizens or Permanent Residents earning more than S$50 per month. Foreign directors and non-resident employees do not attract CPF. Note also that director's fees voted by the board are not wages and carry no CPF, while a director's salary does if that director is a Citizen or PR — a distinction worth getting right before your first payroll run.

☐ 11. Employ at least one local employee if you plausibly can. This is a tax point, not an HR one. For YA 2026 the corporate income tax rebate is 50% of tax payable, capped at S$40,000, and active companies that employed at least one local employee — a Citizen or PR with CPF contributions — in calendar year 2025 receive a minimum benefit of S$2,000, paid as a CIT Rebate Cash Grant where the rebate would be smaller. For a first-year company with little or no tax payable, that local-employee condition is the difference between a rebate worth nothing and a S$2,000 cash grant, disbursed automatically by the second quarter of 2026 and not taxable. Confirm the current year's conditions with IRAS, as rebate parameters are set Budget by Budget. The same local-employee condition gates several other schemes, which is one reason it is worth reading our guide to Singapore government grants and incentives for foreign-incorporated companies before you assume you are ineligible for support.

☐ 12. Apply for the work passes you need. If you intend to relocate yourself or key hires, start now — pass approval governs when you can actually be in the country running the business. See Employment Pass Singapore: can a company director apply.

☐ 13. Check whether your activity needs a licence. Most trading and services companies need none. Regulated activities — financial services, food and beverage, employment agency work, education, travel agency, private security — do, and operating without one is an offence rather than a filing lapse. Check against your SSIC code.

☐ 14. Put Work Injury Compensation insurance in place if you have employees. Required for manual workers regardless of earnings, and for non-manual employees below the prescribed salary threshold. Verify the current threshold with MOM before relying on an exemption.

Phase 3 — Your first annual cycle#

These recur every year. Diarise them the day you fix your FYE.

☐ 15. File Estimated Chargeable Income within 3 months of FYE. You are waived only if you meet both conditions: annual revenue of S$5 million or below, and nil ECI for the Year of Assessment. Meeting one is not enough. Miss the deadline and IRAS may raise an estimated assessment payable in full within one month — and you lose the instalment option, which is a cash-flow problem rather than a paperwork one.

☐ 16. Hold your AGM within 6 months of FYE. Private companies may dispense with the AGM where members agree and financial statements are sent within the prescribed period, but dispensation is a positive step you take, not a default you fall into.

☐ 17. File your annual return with ACRA. Due within 7 months of FYE — or one month after the AGM if you held one earlier. Whichever comes first governs. Holding an early AGM pulls your annual return deadline forward with it.

☐ 18. Test your audit exemption. A private company is exempt from audit if it meets at least two of three thresholds: revenue of S$10 million or less, total assets of S$10 million or less, or 50 or fewer employees. Normally the test applies across two consecutive financial years; a newly incorporated company is assessed on its current financial year in year one. The exemption removes the auditor only — bookkeeping, financial statements and filings remain mandatory. Directors self-assess and carry the liability for getting it wrong. ACRA opened a review of these thresholds in 2026, so re-check them rather than assuming they are static.

☐ 19. File Form C-S, C-S (Lite) or C by 30 November. Form C-S is available to companies with annual revenue of S$5 million or below and does not require financial statements to be submitted, though a tax computation is still required.

☐ 20. Claim the Start-Up Tax Exemption — automatically. Qualifying new companies receive 75% exemption on the first S$100,000 of normal chargeable income and 50% on the next S$100,000, for their first three consecutive Years of Assessment. There is no application; IRAS applies it when you file. Eligibility conditions do apply — notably around shareholder composition, with investment holding and property development companies excluded — so confirm your structure qualifies rather than assuming it. Companies outside SUTE fall back to Partial Tax Exemption: 75% on the first S$10,000 and 50% on the next S$190,000, available to every company every year. Both exemptions, and how they combine with the rebate to produce an effective rate well below the 17% headline, are set out in Singapore corporate tax explained.

The two decisions founders get wrong#

Letting the provider hold everything. Corppass access, the statutory registers, the BizFile filings, the bank relationship — if all of it sits with one firm and none of it sits with you, changing providers becomes a hostage negotiation rather than a decision. Keep your own Corppass administrator and your own copies of every filed document from month one.

Treating the FYE as an administrative afterthought. It is the anchor for your ECI, AGM, annual return and tax filing, and the 18-month first-period allowance is a real planning tool. A default 31 December chosen without thought can hand a company incorporated in November a compliance cycle three weeks after it starts trading.

Where this checklist ends and judgement begins#

Everything above is a deadline you can diarise. What this list cannot tell you is which of these obligations your provider is actually handling, which it will quietly bill as an extra, and whether the firm holding your statutory registers is registered with ACRA under the Corporate Service Providers Act 2024 — mandatory for every firm providing these services since June 2025.

That is the part founders cannot easily verify from a pricing page, and it is the difference between a first year that runs on rails and one spent chasing a firm that has already moved on to the next signup.
