Global Daily Tax News, Singapore Notes New Rules On Prospective GST Registration, (Nov 7, 2025)

The Inland Revenue Authority of Singapore has released guidance on eased rules regarding registration for GST when a taxpayer reasonably expects its taxable turnover to exceed SGD1m in the next 12 months.

The guidance concerns a change that took effect from July 1, 2025.

Previously, GST registration was required within 30 days when a taxpayer expected its turnover to exceed the VAT registration threshold in the next 12 months.

From July 1, 2025, businesses registering for GST under the prospective view are given a two-month grace period to begin charging GST, if the date of forecast is on and after July 1, 2025 – an extension from the previous one-month period.

The guidance sets out rules regarding forecasting turnover and the required evidence to support the taxpayer's estimates; transitional rules; and examples.
