Does this apply to me?

Two questions. The fixed-establishment rule is where most foreign businesses get it wrong.

Is your business established in Singapore (registered office, branch or fixed establishment)?

Do you issue domestic B2B invoices in Singapore?

Singapore: likely outside the issuing mandate — watch e-reporting / cross-border

VAT registration or trading alone, without a fixed establishment, usually keeps you outside Singapore's issuing obligation — but you may still face e-reporting or need to receive structured e-invoices. Confirm your establishment status.

Not in scope for Singapore

With no establishment and no registration or trade in Singapore, the mandate doesn't apply to you today. Revisit this if you open a branch, warehouse or start supplying into Singapore.

In scope — issue structured e-invoices in Singapore

If you registered for GST voluntarily on or after 1 November 2025 you must already transmit invoice data to IRAS via an InvoiceNow-Ready Solution. Existing GST-registered businesses come in between 1 April 2028 and 1 April 2031 according to 2025 total supplies.

In scope to receive in Singapore

There is no receive-side obligation; the duty is to transmit your sales and purchase invoice data to IRAS via an InvoiceNow-Ready Solution.

No dedicated InvoiceNow penalty. IRAS may refuse or revoke the GST registration of voluntary registrants that do not comply; general GST penalties otherwise apply. IRAS has said enforcement will be calibrated in the initial phases.
