Singapore's Goods and Services Tax is a broad-based consumption tax levied on the import of goods and nearly all supplies of goods and services in Singapore. Since 1 January 2024, the GST rate stands at 9 per cent, following a two-step increase from 7 per cent. Whether you are a business owner, freelancer, or consumer, understanding how GST works is important for budgeting, pricing and compliance.
What Is GST and How Does It Work?
GST is a value-added tax. Businesses registered for GST collect the tax from their customers when making a sale and remit it to IRAS. At the same time, they can claim back the GST they paid on their own business purchases (called input tax). The difference between the GST collected and the GST paid is what the business remits to IRAS. If the input tax exceeds the output tax, the business receives a refund.
For consumers, GST is simply added to the price of most goods and services. When you buy a meal, purchase electronics, or hire a service provider, the 9 per cent GST is included in or added to the price you pay. Some supplies are exempt from GST, including the sale and lease of residential properties, financial services, and the import and local supply of investment precious metals.
Who Must Register for GST?
GST registration is compulsory if your taxable turnover exceeds S$1 million in the past 12 months (retrospective basis) or if you can reasonably expect your taxable turnover to exceed S$1 million in the next 12 months (prospective basis). Taxable turnover includes all standard-rated and zero-rated supplies but excludes exempt supplies and out-of-scope supplies.
You must apply for registration within 30 days of the date you become liable. Late registration can result in penalties, including having to account for GST on all taxable supplies made from the date you should have been registered, without being able to recover input tax for that period.
Businesses with turnover below S$1 million can register voluntarily. This can be advantageous if you make primarily zero-rated supplies (such as exports) because you would be able to claim input tax refunds. However, voluntary registration comes with a minimum two-year commitment, and you must comply with all GST filing and record-keeping requirements during that period.
The 9 Per Cent Rate — What Changed
Singapore increased its GST rate in two stages. The rate went from 7 per cent to 8 per cent on 1 January 2023, and then to 9 per cent on 1 January 2024. The government introduced the Assurance Package, worth over S$9 billion in total, to help Singaporeans cope with the increase. This included cash payouts, additional GST Vouchers, U-Save rebates, and Community Development Council vouchers.
For businesses, the rate change required updating accounting systems, repricing goods and services, and managing transitional rules for contracts that straddle the rate change dates. IRAS published detailed guidance on how to handle invoices, credit notes, and deposits during the transition.
Filing GST Returns
GST-registered businesses must file GST returns (known as GST F5 returns) on a quarterly basis, unless IRAS has approved a different filing frequency. Each return covers a prescribed accounting period and must be filed within one month after the end of that period. For example, a return covering January to March must be filed by 30 April.
Returns must be filed electronically through myTax Portal. The return requires you to declare your total value of standard-rated supplies, zero-rated supplies, exempt supplies, total value of GST on purchases, and the net GST payable or refundable. You must also report the value of goods imported under the Major Exporter Scheme or other approved schemes, if applicable.
Late filing attracts a penalty of S$200 immediately, with further S$200 penalties for each completed month the return remains outstanding, up to a maximum of S$10,000. IRAS may also estimate the tax payable and issue a notice of assessment, which attracts additional penalties if not paid on time.
Input Tax Claims — What You Can and Cannot Claim
As a GST-registered business, you can claim back the GST incurred on purchases and expenses that are directly attributable to making taxable supplies. This includes GST on raw materials, office rent, utilities, professional fees, and other business costs. You need a valid tax invoice to support each claim.
However, there are blocked input tax categories where claims are not allowed regardless of business purpose. These include:
- Club subscription fees (including transfer fees)
- Medical and accident insurance premiums for employees (unless compulsory under the Work Injury Compensation Act)
- Medical expenses for employees (unless the business is a medical or dental services provider)
- Benefits provided to the family members of employees
- Costs relating to motor cars (except for businesses in the motor vehicle trade)
If your business makes both taxable and exempt supplies, you are considered a partially exempt trader. You must apportion your input tax between claimable and non-claimable amounts using an approved method. The most common method is the turnover-based formula, where the claimable proportion equals the ratio of taxable supplies to total supplies.
Reverse Charge and Overseas Vendor Registration
Since 1 January 2020, Singapore has implemented a reverse charge mechanism on imported services. If you are a GST-registered business that is not entitled to full input tax credit and you procure services from overseas suppliers, you must account for GST on those imported services as if you were the supplier. This levels the playing field between local and overseas service providers.
From 1 January 2023, the Overseas Vendor Registration regime was extended to cover goods valued at S$400 or less that are imported via air or post. Overseas vendors and electronic marketplace operators with a global turnover exceeding S$1 million and making more than S$100,000 in supplies to non-GST-registered customers in Singapore must register for and charge GST on these low-value goods.
Common GST Pitfalls
Many businesses make avoidable errors with GST. The most common include failing to account for GST on deemed supplies (such as gifts of goods costing more than S$200), claiming input tax without proper tax invoices, not adjusting for bad debt relief within the required timeframe, and miscategorising exempt supplies as out-of-scope. IRAS conducts audits and will raise assessments with penalties and interest for errors discovered. Voluntary disclosure of past errors can reduce the penalties imposed.
Final Thoughts
GST compliance in Singapore is straightforward once you understand the rules. Register on time, keep proper records, file quarterly, and be careful with input tax claims. If you run a small business approaching the S$1 million threshold, start planning early — the costs of late registration far outweigh the effort of registering proactively. For individual consumers, the 9 per cent rate is now a fact of life, and the government's Assurance Package should help cushion the impact over the coming years.
