If your GST return shows a net refund and the money has not arrived, IRAS has most likely either not been able to pay it automatically or has selected the claim for checks. Most GST refunds are paid quickly, but IRAS will not process a refund automatically while returns are outstanding, taxes are unpaid, no electronic refund route is set up, the business is under audit, or requested information has not been supplied. The fastest way to release a held refund is to answer IRAS’s queries completely, with tax invoices, import and export documents and contracts that tie back to the figures in the return.
Raffles Corporate Services works with a panel of experienced Singapore law firms who offer cost-effective and efficient legal service and advice. This article is general information only and is not legal advice.
Why does a GST return end up in a refund position?
A GST refund arises when the input tax you claim in a GST F5 return is more than the output tax you charge. That is normal for some businesses and unusual for others, which is exactly why IRAS looks at refund claims more closely than payable returns. Common refund situations include:
- Exporters and zero-rated suppliers. Sales to overseas customers are charged GST at 0%, while local purchases and imports carry 9% GST, so the business recovers more than it pays.
- New registrants. A company that has just registered may claim GST on pre-registration purchases and set-up costs in its first return, before it has much revenue.
- Large one-off purchases. Buying equipment, fitting out premises or importing a large consignment can push a single quarter into a refund.
None of these is wrong. The question IRAS asks is whether the input tax is properly supported and whether the zero-rated sales genuinely qualify.
How long should a GST refund normally take?
IRAS publishes a refund due date for GST refunds arising from input tax exceeding output tax: one month after it receives the return for businesses on monthly accounting periods, and three months for businesses on quarterly periods. IRAS has said publicly that most GST refunds are paid well within that time.
| Point | What IRAS says | What it means for you |
|---|---|---|
| Refund due date | 1 month (monthly periods) or 3 months (quarterly periods) after IRAS receives the return | A quarterly filer should not panic if the refund is not in the bank within a week |
| Refund route | Paid to the GIRO account if GIRO covers payments and refunds, otherwise by PayNow linked to the UEN | No electronic route means no automatic refund |
| GIRO timing | Refunds credited to the GIRO account within 7 days from when the tax credit arises | GIRO for both payments and refunds is the simplest set-up |
| Offset | Credits are used first to offset outstanding taxes or penalties | Unpaid corporate tax or penalties reduce or wipe out the refund |
| Interest on late refunds | Generally paid if the refund is not made by the due date, unless returns are outstanding, requested information has not been given or taxes are unpaid | Interest is lost if the delay is caused by your side |
Check the current position on the IRAS GST refunds page before relying on these points, because operational details such as refund modes change from time to time.
What makes IRAS hold a refund instead of paying it?
IRAS lists the situations in which tax refunds are not made automatically. For a GST-registered company, the ones that matter most are:
- No electronic refund mode. There is no GIRO arrangement with IRAS and the UEN is not linked to PayNow Corporate.
- Outstanding returns. One or more GST returns have not been filed. IRAS will not release a refund for one period while another is missing.
- Outstanding taxes or penalties. The refund is used to offset them first.
- Audit or investigation. The return, or the business, is being reviewed.
- Information requested but not provided. IRAS has asked questions about the claim or an assessment and is waiting for a reply.
- Suspected fraud arrangements. Where the Comptroller reasonably suspects an arrangement such as missing trader fraud in the supply chain, refunds can be withheld until IRAS is satisfied.
Beyond those formal reasons, certain patterns tend to prompt a review: a first return with a large refund, repeated refunds without an obvious export business, input tax that jumps sharply compared with previous periods, figures that do not match customs import data, and zero-rated sales without matching export records. Our article on what triggers a GST audit explains how a refund review can widen into a full audit if the answers are weak.
What documents does IRAS usually ask for?
IRAS tailors each request to the claim, but the documents follow the source of the refund. Expect to be asked for evidence that the purchases were made, were for the business, and that zero-rated sales really left Singapore or went to qualifying overseas customers.
| Reason for the refund | Documents to have ready |
|---|---|
| Large local purchases or equipment | Valid tax invoices addressed to the company, purchase contracts or quotations, proof of payment, delivery orders, fixed asset register |
| Imports | Import permits showing the company as importer, payment records for import GST, supplier invoices, freight documents |
| Export of goods (zero-rated) | Purchase orders, sales invoices, bills of lading or air waybills, export permits, packing lists, proof of payment from the overseas customer |
| International services (zero-rated) | Service contracts showing the overseas customer, evidence of who benefits from the service, invoices and payment records |
| Pre-registration claims in a first return | Tax invoices for goods still held at registration, list of services received within the claim window, evidence that the costs relate to the taxable business |
| New or unusual business | Description of business activities, customer and supplier lists, sample contracts, bank statements, website or premises details |
For exports, timing matters as much as the paperwork. IRAS’s guidance on exporting goods requires the export documents supporting zero-rating to be held within 60 days from the time of supply, subject to limited exceptions. If those documents are missing, the sale should have been standard-rated, and IRAS will reduce the refund accordingly. Our guide to zero-rating exports sets out the document sets in more detail.
How should you respond to an IRAS query on a refund?
- Read the request carefully and note the deadline. Answer the questions asked. If a deadline is too short to gather overseas documents, ask IRAS for more time before it passes rather than after.
- Reconcile before you send. Tie the box totals in the GST F5 to the general ledger, the purchase and sales listings, and for imports, the customs data. A mismatch you explain upfront is far better than one IRAS finds.
- Send organised evidence. Provide a schedule listing each invoice queried, with the supplier, date, GST amount and the supporting document reference, then attach the documents in the same order.
- Explain the business, briefly. For a first refund, a short note on what the company does and why it is in a refund position helps.
- Correct what is wrong. If the review shows an invoice that is not a valid tax invoice, a private expense or a sale that should have been standard-rated, say so and correct it rather than defend it.
- Keep a record of the request, your reply and the date sent.
What if the review reveals an error in the return?
Errors are often discovered when a business pulls documents together for IRAS. Under IRAS’s rules on correcting errors in GST returns, small errors can be adjusted in the next GST F5 only if the net GST in error is not more than S$3,000 across the affected periods and the other conditions are met. Errors in pre-registration claims, larger errors and any correction that results in a refund need a GST F7. Errors must be corrected within five years from the end of the accounting period concerned.
If IRAS has already started reviewing the refund, raise the error with the officer handling the case, and do not assume the reduced penalty treatment for voluntary disclosures will apply in full. Our guide to the IRAS Voluntary Disclosure Programme explains how timing affects penalties.
Example: a new trading company’s first refund
Example: A hypothetical company registers for GST in July and files its first quarterly return showing a refund, mostly from import GST on its first container of stock and GST on a warehouse fit-out. Its sales in the quarter are small and mostly zero-rated exports to Malaysia. Six weeks later, it has not received the refund, and IRAS emails asking for import permits, the fit-out contract and evidence of the export sales.
The finance team finds that one export shipment has no bill of lading because the customer collected the goods from the warehouse and the company did not obtain the required export evidence. It also notices that the company had not set up GIRO for refunds. The team sends the import permits and contract with a reconciliation schedule, standard-rates the one undocumented sale and accounts for the GST on it, and links the UEN to PayNow Corporate. IRAS then processes the reduced refund.
Checklist: keep a refund claim easy to verify
- GIRO for payments and refunds, or the UEN linked to PayNow Corporate
- All earlier GST returns filed and all taxes and penalties paid
- Box-by-box reconciliation of the GST F5 to the ledger, kept with the return
- Valid tax invoices in the company’s name for every significant input tax claim
- Import permits matched to the import GST claimed
- Export documents held within 60 days of the time of supply
- Contracts showing overseas customers for zero-rated services
Good habits here overlap with the wider GST record-keeping requirements, so building them once helps with both refunds and audits.
Frequently asked questions
Will IRAS pay interest if my GST refund is late?
IRAS states that it generally pays interest when a GST refund is not made by the due date. Interest is not paid where you have unfiled GST returns, have not complied with requests for information during an audit, or have outstanding taxes or penalties. The rate is set with reference to the Singapore Overnight Rate Average.
Does a refund review mean IRAS suspects us of wrongdoing?
Not necessarily. Many reviews are routine checks on first refunds, large claims or export-heavy businesses. Answer fully, but it is not an accusation.
Our refund was used to pay corporate income tax. Is that allowed?
Yes. IRAS states that tax credits are used to offset outstanding taxes or penalties. If the outstanding amount is larger than the GST credit, you will not receive a GST refund for that period.
We are always in a refund position because we import heavily and export most goods. Is there a better option?
Businesses whose supplies are mainly zero-rated can look at the Major Exporter Scheme, which can suspend import GST on non-dutiable goods for approved businesses. Approval depends on IRAS’s conditions, so check eligibility before relying on it.
