The GST InvoiceNow Transition Grant is a fixed S$1,000 from IMDA for GST-registered businesses with 2025 supplies of S$4 million or less that take up a new, paid InvoiceNow-Ready Solution and start submitting invoice data to IRAS before their mandatory date.
It is an IMDA grant, and there is no grant application: once you meet the criteria, you submit a claim form to IMDA. The grant runs from 1 July 2026 to 31 March 2030, or until it is fully claimed, whichever is earlier.
What the grant covers
IMDA pays the same S$1,000 whatever you actually spend. The qualifying costs are:
- •A subscription to an IMDA-accredited InvoiceNow-Ready Solution, with payment for at least 12 months. A lifetime licence also counts.
- •The cost of connecting your own ERP or in-house system to InvoiceNow through an IMDA-accredited Access Point Provider.
Costs must be incurred after 26 February 2026 and before your mandate date. Monthly bills count once they add up to 12 months of payments, and they need not be consecutive.
What does not count: free-of-charge InvoiceNow packages, because there is no cost to defray, and renewals of a subscription you already have.
Eligibility
IMDA lists five criteria for the S$1,000 grant. You must meet all of them:
The test is your 2025 supplies, not your headcount. Sole proprietorships, partnerships, LLPs and companies can all qualify. IMDA’s FAQs also exclude:
- •Businesses that register for GST voluntarily on or after 1 April 2026. InvoiceNow is already a condition of their registration.
- •Businesses that have received, or are claiming, other government funding for the same solution or subscription.
- •Government entities and government-owned entities, including NGOs.
Full criteria are on IMDA’s InvoiceNow Grants page and in the grant FAQs (PDF).
How to claim — step by step
- 1Check your date and your 2025 supplies. IRAS has been notifying businesses registered before 2026 of their mandatory date since mid-2026, and publishes a calculator. Your 2025 supplies are the Box 4 totals (standard-rated, zero-rated and exempt supplies) on your returns for periods ending in 2025. See GST InvoiceNow: when is your mandatory date?
- 2Choose an IMDA-accredited solution. Pick one from IMDA’s list of accredited InvoiceNow-Ready Solution Providers or, if you run your own ERP, work with an IMDA-accredited Access Point Provider. Free-of-charge packages meet the IRAS requirement but do not qualify for the grant.
- 3Pay for at least 12 months. Pay after 26 February 2026 and before your mandate date. Monthly bills count once they add up to 12 months of payments.
- 4Activate GST InvoiceNow and submit data to IRAS. Do this before your mandate date. Your solution provider or Access Point can confirm that GST InvoiceNow is activated.
- 5Submit the claim form. There is no application first. Submit IMDA’s S$1,000 claim form with proof of costs and proof of payment. You can claim before the 12 months are up if you can show payment for the full 12 months. Payment is by PayNow Corporate, within approximately two months of submission. Questions and appeals go to IMDA through its InvoiceNow contact form.
Timing matters
The grant window runs to 31 March 2030, or until the grant is fully claimed, and supporting documents are accepted until 31 December 2030. Your own cut-off is your mandate date: costs must fall before it, and GST InvoiceNow must be activated and sending data to IRAS by then.
For existing GST-registered businesses, IRAS sets the date by 2025 supplies: 1 April 2028 for S$200,000 or less, 1 April 2029 for S$1 million or less, and 1 April 2030 for S$4 million or less. If IRAS has notified you of a date, that date applies.
IRAS says onboarding can take as little as three months, and most businesses finish within a year. If you are leaving a free solution, add the 3-month wait-out on top.
Supplies above S$4 million
Businesses with 2025 supplies above S$4 million can claim a separate fixed S$5,000, but only for connecting their own ERP or in-house system to GST InvoiceNow through an IMDA-accredited Access Point. The project must start after 26 February 2026, take no more than 12 months, and be finished, with invoice data going to IRAS, by 31 March 2028. That grant runs from 1 July 2026 to 31 March 2028, or until it is fully claimed.
Businesses with turnover above S$4 million, their own ERP and at least 200 suppliers or business customers may also be eligible for the S$25,000 InvoiceNow Queen Bee Grant, which starts with an expression of interest to IMDA.
Questions
How much is the GST InvoiceNow Transition Grant?
A fixed S$1,000 for eligible businesses with 2025 supplies of S$4 million or less, paid regardless of what you actually spent. Businesses above S$4 million that connect their own ERP system through an IMDA-accredited Access Point can qualify for a separate fixed S$5,000 grant.
Do I apply on the Business Grants Portal?
No. It is an IMDA grant with its own claim form, and there is no application on the Business Grants Portal. If you have received, or are claiming, other government funding for the same solution or subscription, you cannot also claim this grant.
Who is eligible for the S$1,000 grant?
GST-registered businesses in Singapore with total annual supplies of S$4 million or less in 2025. After 26 February 2026 you must take up a new IMDA-accredited InvoiceNow-Ready Solution with at least 12 months paid, or connect your own ERP through an IMDA-accredited Access Point, then activate GST InvoiceNow and submit data to IRAS before your mandate date. You must not have used any InvoiceNow-Ready Solution in the 3 months before.
Can I claim the grant if I use a free InvoiceNow solution?
No. Free-of-charge packages carry no qualifying cost. You can move to a paid accredited solution and claim, but only after a 3-month wait-out that starts when you are de-registered from the InvoiceNow network and your free account is deleted. If the wait-out ends after your mandate date, you cannot qualify.
I registered for GST voluntarily on or after 1 April 2026. Can I claim?
No. Businesses that register for GST voluntarily on or after 1 April 2026 must adopt GST InvoiceNow as a condition of registration, so they are not eligible.
Does renewing my existing subscription count?
No. Only a new subscription or new purchase of an accredited solution qualifies. If you already subscribe to an InvoiceNow-Ready Solution, you are not eligible, even if you have never switched on GST InvoiceNow.
How do I claim, and when is it paid?
There is no application. Submit IMDA's claim form with proof of costs, such as the invoice for your annual subscription, and proof of payment. Successful claims are paid through PayNow Corporate within approximately two months of submission, and IMDA emails you when the payout is made.
