The updated GST e-Tax Guides will revise registration timelines and ease GMS adoption requirements.
The Inland Revenue Authority of Singapore (IRAS) has revised multiple Goods and Services Tax (GST) e-Tax Guides, effective from 1 July 2025, addressing prospective GST registration rules and changes to the Gross Margin Scheme (GMS).
From 1 July 2025, businesses forecasting taxable turnover exceeding SGD 1 million in the next 12 months must register for GST within 30 days of the forecast. However, GST registration will take effect two months after the forecast date. This extends the current rule, under which GST is charged from the 31st day after the forecast.
Additionally, multiple e-Tax Guides have been updated to reflect that, from 1 July 2025, eligible businesses may adopt the GMS without prior approval from IRAS. Corresponding updates to relevant paragraphs and documents have been made across several guides.
Guide-specific updates:
- Overseas Vendor Registration Regime – LVG (4th Ed.)
Paragraph 7.1.11 updated for prospective registration rules effective 1 July 2025, plus editorial changes. - Overseas Vendor Registration Regime – Remote Services (5th Ed.)
Paragraph 7.1.11 updated with new prospective registration rules from 1 July 2025, along with editorial revisions. - Hire Purchase Agreements and Financing Instruments (5th Ed.)
Amendments to paragraphs 7.1 and 7.3: Businesses eligible to apply GMS from 1 July 2025 no longer need IRAS approval. - Motor Vehicle Traders (9th Ed.)
GMS approval requirement removed from 1 July 2025. The declaration form is replaced with a checklist for eligibility. - Customer Accounting for Prescribed Goods (9th Ed.)
Paragraph 12.1.5 revised to reflect eligibility-based GMS use, removing the phrase “approved to use the GMS.” - Reverse Charge (9th Ed.)
Paragraphs 10.1.3 and 14.18 updated for the new prospective registration rules effective 1 July 2025, with additional editorial updates.
