NOVEMBER 10, 2025

The Inland Revenue Authority of Singapore (IRAS) updated its guidance on completing goods and services tax (GST) returns.

  • Includes box-by-box instructions for Form GST F5—covering standard-rated, zero-rated, and exempt supplies; taxable purchases; output and input tax; and specific disclosures for imports and special schemes
  • Highlights reporting imports of goods under the Import GST Deferment Scheme (IGDS) in Box 5 and editorial changes to remove cheque payment as an option for voluntary disclosure for wrongful GST collection

The IRAS also updated its guidance on cancelling GST registrations.

  • Details compulsory cancellation within 30 days for ceased businesses or entity changes, and voluntary cancellation if not liable for registration (voluntary registrants must remain registered for at least two years before cancellation)
  • Revises the paragraph on "Accounting for GST on assets in the final GST F8" to include "open market value" for greater clarity
