Singapore GST at a glance
Goods and Services Tax is Singapore's broad-based consumption tax, currently 9% (from 1 January 2024). Applied at point of sale on nearly all goods and services. Exemptions: residential property rent/sale, most financial services, digital tokens, and investment-grade precious metals.
Registration threshold
Businesses must register for GST once taxable turnover exceeds S$1 million in a calendar year (or is expected to). Voluntary registration is available below that, enabling input tax credits — worth it if suppliers charge more GST than you collect.
Overseas vendor and imported services
Since 1 Jan 2023, overseas digital services (Netflix, Spotify, AWS) are GST-taxable under the OVR scheme. Low-value goods (under S$400) shipped from abroad also now attract 9% GST. Effectively, there is no way around the 9% on consumer goods.
Tourist refund (TRS)
Tourists leaving Singapore with goods over S$100 can claim GST refund at Changi — minus an administrative fee. Present goods unused and receipts within 2 months of purchase. Best for big-ticket electronics and luxury.
Frequently Asked Questions
Everything you need to know, in one place.
What is the current Singapore GST rate?
9% from 1 January 2024. Rose from 7% (pre-2023) → 8% (2023) → 9% (2024 onwards). Applied at point of sale on nearly all goods and services, with exempted categories including financial services and residential rentals.
When must a business register for GST?
Compulsory registration once taxable turnover exceeds S$1M in a calendar year (or is expected to). Voluntary registration available below threshold — allows claiming input tax but adds compliance overhead.
What is GST absorption?
Many Singapore retailers advertise "prices inclusive of GST" — the 9% is built into the sticker price. Check if receipts show GST separately; if not, the price already includes it.
Does GST apply to my online purchases?
Yes — since 2023, overseas digital services (Netflix, Spotify, AWS) and low-value goods under S$400 shipped to Singapore are subject to 9% GST via the Overseas Vendor Registration scheme.
How does a GST-registered business file returns?
Filing is quarterly by default (monthly for large businesses with supplies >S$5m). Via myTax Portal: declare standard-rated supplies, zero-rated supplies, exempt supplies, input tax, and net GST payable/refundable. Due within one month of the accounting period end. Late filing: S$200 penalty + 5% of tax due after 60 days. Keep source documents 5 years. GST returns also require accurate Box 5 (total taxable purchases) — mismatches with income tax filings trigger IRAS queries.
How do I remove 9% GST from a price?
Pre-GST = GST-inclusive price ÷ 1.09. Example: S$109 inclusive = S$100 + S$9 GST. S$545 inclusive = S$500 + S$45. Do not subtract 9% directly — that overstates the pre-GST amount by about 0.74%. For reverse calculations on business expenses, keep tax invoices from GST-registered suppliers (must show GST number, breakdown, and supplier's name/address) for input tax credit claims.
