If your Singapore business is GST-registered, there is a time-sensitive opportunity you should not miss. Since 1 July 2026, IRAS and IMDA have been offering tiered cash grants of up to S$25,000 to businesses that adopt the InvoiceNow e-invoicing network. The grants are first-come, first-served — and one tier closes as early as March 2028.

This guide explains how the three grant tiers work, who qualifies, how to apply, and why acting now gives your business an advantage before the mandatory InvoiceNow rollout expands to all GST-registered businesses.

What Is InvoiceNow?

InvoiceNow is Singapore’s national e-invoicing network, built on the international Peppol standard. It allows businesses to send and receive structured electronic invoices directly between accounting systems, without manual data entry, PDF invoices, or email attachments.

IRAS uses InvoiceNow to receive invoice data for GST compliance purposes. When a business connects to InvoiceNow, every invoice it issues is simultaneously transmitted to IRAS in real time, automating much of the GST record-keeping obligation.

InvoiceNow is already mandatory for all new voluntary GST registrants from 1 November 2025, and the mandate is expanding progressively to all existing GST-registered businesses by April 2031. The adoption grants are designed to accelerate take-up ahead of that mandatory deadline. For more on Singapore’s GST obligations generally, see our GST Registration Singapore 2026 guide.

The Three InvoiceNow Adoption Grant Tiers

Tier 1: S$1,000 for Small GST-Registered Businesses

Who qualifies: GST-registered businesses with annual taxable supplies of S$4 million or below that subscribe to an accredited InvoiceNow Ready Solution Provider (IRSP) or connect through a Peppol Access Point.

Grant amount: S$1,000 (one-time). Available until: 31 March 2030.

This tier covers the vast majority of Singapore SMEs. If your business uses accounting software such as QuickBooks, Xero, or any other IRSP-accredited solution, connecting to InvoiceNow may be as simple as enabling a feature within your existing subscription.

Tier 2: S$5,000 for Mid-Sized Businesses Integrating ERP Systems

Who qualifies: Businesses with annual taxable supplies above S$4 million that integrate their own ERP or accounting system with InvoiceNow via a Peppol Access Point.

Grant amount: S$5,000 (one-time). Available until: 31 March 2028 — the shortest window.

This tier is for businesses operating ERP systems such as SAP, Oracle, or Microsoft Dynamics. Because this tier closes in March 2028, businesses should prioritise their applications now to avoid missing the window.

Tier 3: S$25,000 for Large Enterprises Building InvoiceNow Networks

Who qualifies: Large enterprises that actively build a trading network of at least 200 suppliers or customers connected via InvoiceNow.

Grant amount: S$25,000 (one-time). Available until: 31 March 2030.

This tier is aimed at anchor businesses — large corporates, retailers, or procurement hubs — that can drive InvoiceNow adoption across their supply chains.

Eligibility Requirements

To qualify for any tier of the InvoiceNow adoption grant, your business must:

  • Be registered for GST in Singapore (compulsory or voluntary).
  • Have completed InvoiceNow integration or onboarding on or after 26 February 2026.
  • Have submitted at least one invoice to IRAS via InvoiceNow after integration.
  • Use an accredited IRSP or connect through a registered Peppol Access Point.

Businesses that connected to InvoiceNow before 26 February 2026 do not qualify for these specific adoption grants. A full list of accredited IRSPs is available on the IMDA website.

How to Apply: Step by Step

Step 1: Confirm Your GST Registration and Annual Supply Tier

Check your most recent GST return to confirm whether your annual taxable supplies are above or below S$4 million. This determines whether you apply for Tier 1 or Tier 2.

Step 2: Choose an Accredited IRSP or Peppol Access Point

Visit the IMDA website and select an accredited solution provider. If you already use accounting software, check whether it is on the IRSP list — many common packages are accredited.

Step 3: Complete the InvoiceNow Onboarding

Subscribe to the IRSP or connect via the Access Point. Configure your accounting or ERP system to send outbound invoices in Peppol format through the InvoiceNow network.

Step 4: Send Your First InvoiceNow Invoice to IRAS

Grant eligibility is triggered once your business has submitted at least one invoice via InvoiceNow, confirming the connection is live and functional.

Step 5: Apply Through the Business Grants Portal

Submit your grant application through the Business Grants Portal (BGP). IRAS and IMDA will validate your submission and disburse the grant after confirming eligibility.

Stacking the InvoiceNow Grant with Other Grants

The InvoiceNow adoption grant is separate from the Productivity Solutions Grant (PSG), which can fund up to 50% of an accredited accounting or ERP software solution cost. A business could potentially claim the PSG for its accounting software and separately claim the InvoiceNow adoption grant for connecting that software to InvoiceNow.

Why Act Now Rather Than Later?

Three practical reasons to move quickly:

First, the grants are first-come, first-served. There is no guarantee funds will remain available until the advertised closing dates.

Second, the Tier 2 grant (S$5,000) closes on 31 March 2028 — nearly two years before the other tiers. Businesses with ERP systems that delay their InvoiceNow integration risk missing this window entirely.

Third, early adopters gain operational advantages: real-time invoice delivery, reduced manual keying errors, faster payment cycles, and a head start on compliance. For sound business financial management, getting ahead of regulatory changes is always preferable to rushing to comply under deadline pressure.

The InvoiceNow Mandate Timeline

The adoption grants are part of Singapore’s broader drive to digitalise business-to-business invoicing. Key milestones:

  • 1 November 2025: InvoiceNow mandatory for all new voluntary GST registrants.
  • 2028–2031: Phased expansion to existing GST-registered businesses by size and sector.
  • April 2031: Target for full coverage across all GST-registered businesses.
