Key takeaways
- All GST-registered businesses will eventually have to submit invoice data to IRAS via InvoiceNow — Singapore’s nationwide Peppol-based e-invoicing network, introduced by IMDA in 2019 — under IRAS’s GST InvoiceNow Requirement, rolled out in phases from November 2025 to April 2031.
- The mandate is already live for new voluntary GST registrants: since 1 November 2025 for companies registering within 6 months of incorporation, and from 1 April 2026 for every other voluntary registrant regardless of incorporation date.
- Existing GST-registered F&B businesses are phased in by turnover — total annual supplies (Box 4 of your GST return) ≤$200,000 from 1 April 2028, up to the largest businesses (>$4,000,000) from 1 April 2031.
- IRAS said it will individually notify existing GST-registered businesses of their exact implementation date by mid-2026 — in the meantime you can self-check using IRAS’s GST InvoiceNow Implementation Date Calculator.
- Support is available to offset onboarding cost: a GST InvoiceNow Transition Grant ($1,000 for SMEs, $5,000 for larger businesses) plus free-of-charge InvoiceNow-Ready solution packages running until at least 31 March 2027.
If your F&B business is GST-registered — or you’re thinking about voluntary registration to reclaim input tax on kitchen fit-outs, equipment or supplier invoices — a new compliance clock is already running. IRAS’s GST InvoiceNow Requirement will eventually require every GST-registered business to transmit its invoice data straight to IRAS through the InvoiceNow network, and the first phases have already taken effect. Here’s what it actually requires, when it hits your outlet, and what help is on offer.
What is InvoiceNow, and how is it different from just filing GST returns?
InvoiceNow is Singapore’s nationwide e-invoicing network, built on the international Peppol standard and introduced by the Infocomm Media Development Authority (IMDA) back in 2019. It lets businesses send and receive invoices as structured digital data rather than PDFs or paper, moving straight between accounting systems.
The GST InvoiceNow Requirement builds on that network: once a GST-registered business activates the feature in an InvoiceNow-Ready Solution, IRAS receives a copy of each invoice’s data automatically via an IMDA-accredited Access Point Provider. That’s separate from — and in addition to — your existing periodic GST return filing; it’s meant to let IRAS pre-fill and cross-check GST returns over time, not replace the filing itself.
When does the mandate actually apply to my F&B business?
IRAS is rolling this out progressively rather than all at once. The implementation date depends on how and when you’re GST-registered:
| Implementation date | Who it applies to |
|---|---|
| 1 November 2025 | Companies that register for GST voluntarily within 6 months of incorporation date |
| 1 April 2026 | Businesses that apply for voluntary GST registration on or after 1 Apr 2026, regardless of incorporation date or structure |
| 1 April 2028 | Businesses that apply for compulsory GST registration on/after 1 Apr 2028; existing GST-registered businesses with total annual supplies ≤ $200,000 |
| 1 April 2029 | Existing GST-registered businesses with total annual supplies ≤ $1,000,000 |
| 1 April 2030 | Existing GST-registered businesses with total annual supplies ≤ $4,000,000 |
| 1 April 2031 | Existing GST-registered businesses with total annual supplies > $4,000,000 |
If you registered for GST before 2026, don’t wait for the letter: IRAS says it will notify existing GST-registered businesses of their specific mandatory date by mid-2026, but you can check your own tier now using IRAS’s GST InvoiceNow Implementation Date Calculator, based on your GST returns for calendar year 2025.
What do I actually have to set up to comply?
You need an InvoiceNow-Ready Solution — accounting or finance software capable of transmitting invoice data over the InvoiceNow network. If you use off-the-shelf software, check it against IMDA’s list of accredited InvoiceNow-Ready Solution Providers, register your business in the SG Peppol Directory with your UEN to obtain a Peppol ID, then switch on the GST InvoiceNow submission feature. Businesses running in-house enterprise systems instead work directly with an IMDA-accredited Access Point Provider.
What financial support is available for onboarding?
IRAS and IMDA have put grants and free options in place given the compliance work involved. SMEs can tap a GST InvoiceNow Transition Grant of $1,000, with larger businesses eligible for $5,000; there’s also a Queen Bee Grant for larger firms that help onboard their supply chains. Separately, GST-registered businesses can pick from a list of free-of-charge InvoiceNow-Ready solution packages, available until at least 31 March 2027 (IRAS and IMDA are to publish updated FOC packages covering the period through 31 March 2031). Full eligibility details sit with IMDA, not IRAS.
What happens if I miss my implementation date?
IRAS’s own InvoiceNow requirement page doesn’t spell out a specific penalty for missing your implementation date — it frames this as a data-transmission and reporting obligation layered onto your existing GST compliance, not a standalone offence with its own fine schedule. Separately, if any GST errors arise (whether related to InvoiceNow reporting or otherwise), IRAS’s general Voluntary Disclosure Programme still applies: errors disclosed within the 1-year grace period from your statutory filing deadline may qualify for a full penalty waiver, and those disclosed after the grace period may qualify for a reduced flat 5% penalty on the GST undercharged, subject to IRAS’s standard conditions. The practical risk of missing your implementation date is falling behind and scrambling once IRAS has assigned your compliance tier, so it’s worth confirming your date and getting an InvoiceNow-Ready system in place ahead of time rather than at the deadline.
Frequently asked questions
Does InvoiceNow replace my regular GST return filing?
No. Transmitting invoice data via InvoiceNow is a separate, additional obligation on top of your existing periodic GST return filing — it feeds IRAS structured invoice-level data that can eventually help pre-fill or cross-check your return, but it doesn’t remove the filing requirement itself.
My F&B business isn’t GST-registered — does this affect me?
Not directly yet. The GST InvoiceNow Requirement only applies to businesses that are GST-registered, whether compulsorily (once taxable turnover exceeds the registration threshold) or voluntarily. If you register voluntarily, though, be aware it can now trigger an InvoiceNow implementation date depending on when you apply.
How do I find out my exact implementation date if I registered for GST before 2026?
Use IRAS’s GST InvoiceNow Implementation Date Calculator, which works off your GST returns for calendar year 2025, or wait for IRAS’s direct notification, which it says will be sent to existing GST-registered businesses by mid-2026.
Can I keep using my current accounting software?
Only if it’s on IMDA’s list of accredited InvoiceNow-Ready Solution Providers, or you connect it to an accredited Access Point Provider. Check your software vendor’s own InvoiceNow support and Peppol registration status before your implementation date arrives.
Is there really no cost to get compliant?
It can be low-cost: IRAS and IMDA list free-of-charge InvoiceNow-Ready solution packages for GST-registered businesses, and separately offer Transition Grants ($1,000 for SMEs, $5,000 for larger businesses) toward onboarding costs. Confirm current eligibility and package availability directly with IMDA before assuming a specific option still applies to you.
