TIMELINE

Phased from 2025 to 2031. If you are already GST-registered, your phase depends on your total annual supplies. Total annual supplies means the total value of standard-rated, zero-rated and exempt supplies (Box 4 of the GST return) made in all prescribed accounting periods ending in calendar year 2025.

CALCULATOR

GST InvoiceNow Implementation Date Calculator

Go by your IRAS MyTaxMail letter. IRAS has notified GST-registered businesses that were registered before 2026 of their mandatory implementation date from mid-2026. Businesses without GST returns for periods ending in 2025 will be told their date later. This calculator is only indicative. IRAS also publishes its own calculator spreadsheet.
