Closing a sole proprietorship or company: strike off, winding up and GST de-registration
8 min read
Closure is now a routine part of the small-business landscape here — that is our reading of ACRA's figures, not a claim the agency makes. CNA TODAY reported on 11 September 2026 that, from January to August 2026, 56,548 business entities were formed in Singapore while 42,741 ceased. [1]
The practical detail sits in the agencies' own guidance. For a local company the route is decided by debts rather than preference: ACRA states you can strike off a company that is inactive and debt-free, or wind up a company that has debts to settle. On the strike off route, IRAS states that companies must settle all outstanding tax liabilities and obligations with IRAS before applying to ACRA. [2] [3]
Debts, not preference, decide which exit you take
Winding up is, in ACRA's words, the formal process for closing a local company that has debts to settle: settle all debts and obligations, distribute remaining assets to partners, and file the required legal notifications with ACRA. ACRA lists four ways to wind up based on the company's financial health. One is the Simplified Winding Up Programme, a simplified creditors' process under the Simplified Insolvency Programme, described as applying when a micro or small company cannot pay its debts and wants to wind up. ACRA defines a micro company as one with annual revenue under $1 million and a small company as one under $10 million. [4]
Where the members' or partners' voluntary route applies, ACRA frames the test around directors who believe the variable capital company can pay all debts within 12 months of starting the winding up process, and requires a liquidator or provisional liquidator to be appointed, along with the necessary notifications under the Companies Act 1967 or the Insolvency, Restructuring and Dissolution Act 2018. ACRA's own note on that page is to refer to those statutes, or seek professional advice. [4]
Two situations, hypothetically. A company that has stopped trading and owes nobody sits close to ACRA's strike-off description; one still owing suppliers, a landlord or a lender sits closer to the winding-up description. An unpaid customer invoice is the awkward case, because that is money owed to the company rather than by it, and ACRA's closing page does not explain how receivables are treated. Confirm that position with ACRA or a professional adviser rather than treating the headline rule as settled. [2]
IRAS first for a strike off: what 'settled' actually means
IRAS treats tax matters as settled when all Corporate Income Tax Returns — Form C-S, Form C-S (Lite) or Form C — are filed up to the date of business cessation. A company filing Form C must also submit the financial statements or certified accounts and the tax computations for the relevant Year of Assessment. These go through mytax.iras.gov.sg, and from 1 August 2026 IRAS no longer accepts those documents by other modes. IRAS also states that it does not issue tax clearance letters for the purpose of applying for strike off, pointing owners instead to the latest Notice of Assessment and latest Statement of Accounts. [3]
File too early and the timetable moves. IRAS states it will object where tax matters remain outstanding, that the objection must be resolved within two months from the objection date, and that if it is not, the company must submit a new ACRA strike off application after the objection is cleared. Two warnings sit alongside: do not close the company's bank accounts until all matters are settled, because a tax credit owing then cannot be paid to a director or shareholder; and on dissolution any tax credit due to the company goes to the Insolvency Office, which charges for processing a shareholder's claim. [3]
Then ACRA: three filings, three fees, in a fixed order
For a solvent company on a members' or partners' voluntary winding up, ACRA publishes a fixed sequence of three Bizfile filings. First the declaration of solvency, which ACRA describes as applying where the entity is solvent: no fee, immediate processing. Second the notice of resolution, which ACRA says must be filed after the declaration of solvency: free, immediate. Third the appointment of a liquidator or provisional liquidator, listed as the final required filing and requiring both earlier filings in place, with at least one liquidator: $20, immediate. All three run through the File winding up of business entity eService. [5] [6] [7]
The creditors' route starts earlier rather than differently: ACRA states the notice of resolution is a required filing and, where no declaration of inability to continue business was filed, the first of two required filings. Tax filings do not pause. IRAS requires a Declaration of Receipts and Payments throughout the liquidation — on a yearly basis for companies with receipts, or within six months before the Final Meeting or once every four years, whichever is earlier, for companies with no receipts — along with replies to all queries raised. [8] [9]
Closing a sole proprietorship: prerequisites, one filing, no reversal
An unincorporated business closes more cheaply, but not on a single click. Before filing, ACRA requires the business to have settled all administrative matters — completing ongoing contractual obligations, transferring vehicle ownership, resolving outstanding loans or grants linked to the business — and to have cancelled its GST registration if applicable. An expired business registration must be renewed before the business can be closed. [10]
The cessation itself is free with immediate processing through the File cessation or dissolution of business entity eService, and it cannot be reversed once ACRA approves it. Timing follows the date you enter: a past or current cessation date moves the status to 'Ceased registration' at once, while a future-dated cessation shows as 'To be ceased' until that date and updates automatically on it. [10]
GST de-registration and what outlives the registration
GST de-registration carries its own clock whichever entity form you use. IRAS states you must apply to cancel GST registration within 30 days when your business has ceased, and that the final GST F8 must be submitted and the GST accounted for within one month from the end of the prescribed accounting period stated on that return, with all outstanding GST returns filed and any outstanding GST payment made. [11]
That final return also carries an asset test. Output tax at the prevailing rate is due on assets for which input tax had been claimed, and on assets obtained as part of business assets transferred to you as a going concern by a GST-registered person, where their total open market value exceeds $10,000 — business assets including non-residential properties, fixed assets such as computers, machinery and vehicles, and unsold inventory. That output tax does not apply where the total open market value is $10,000 or less, or where you have transferred the whole of your business as a going concern to another GST-registered person. [11]
Records then outlive the registration in either route: self-employed individuals including sole-proprietors and partners must keep accounting records and supporting documents for five years, and for companies and LLPs the duty runs five years after the entity is struck off, dissolved or wound up, resting on the officer immediately before dissolution or, in a liquidation, on the liquidator. So choose by debt rather than preference, and sequence the work the same way each time — settle with IRAS, then file with ACRA, then keep what the agency still asks you to hold. The published ACRA filing fees are small, at no fee, free and $20, but a liquidator's own charges and any professional fees are separate matters to check on the agencies' current pages. [12] [13]
