What is Singapore GST Calculator (9%)?
▾
The Singapore GST (Goods and Services Tax) calculator helps businesses and consumers determine the GST component of a transaction or add GST to a net price to arrive at the final inclusive price. Singapore's GST is a broad-based consumption tax levied on almost all goods and services supplied in Singapore, and on imports. The GST rate increased to 9% on 1 January 2024, up from 8% in 2023 and 7% before 2023. This makes accurate GST calculation essential for businesses issuing tax invoices and consumers understanding pricing. There are three GST categories: standard-rated (9%), zero-rated (0%), and exempt. Standard-rated supplies include most goods, services, and imports consumed in Singapore. Zero-rated supplies include exports of goods, international services, and supplies to overseas customers — these are taxed at 0% so businesses can claim input tax credits without charging output tax. Exempt supplies include financial services, sale or lease of residential properties, investment precious metals, and importation of investment precious metals. GST-registered businesses with annual taxable turnover exceeding $1 million must register for GST and file quarterly returns with IRAS. Voluntary registration is possible for smaller businesses. As a registered business, you collect GST on sales (output tax) and can offset GST paid on purchases (input tax), remitting only the difference to IRAS. The calculator helps both consumers (to understand the GST component of any price) and businesses (to price their services correctly at 9%).

Formula
▾
GST Amount = Net Price × 0.09; Price Including GST = Net Price × 1.09; Net Price from Inclusive = Inclusive Price / 1.09; GST Component from Inclusive = Inclusive Price - (Inclusive Price / 1.09)How to Singapore GST Calculator (9%)
▾
- 1Determine whether the supply is standard-rated (9%), zero-rated (0%), or exempt (no GST).
- 2For standard-rated supplies: multiply the net price by 9% to find the GST amount.
- 3Add the GST to the net price to get the total GST-inclusive price for invoicing.
- 4To extract GST from an inclusive price: divide the inclusive price by 1.09 to get the net price, then subtract.
- 5For zero-rated supplies, charge 0% GST but still file GST returns and can claim input tax credits.
- 6For exempt supplies, do not charge GST and cannot claim input tax credits on related expenses.
- 7File quarterly GST F5 returns with IRAS declaring output tax collected and input tax claimable.
Worked Examples
▾
Standard rate 9% from January 2024
A Singapore GST-registered professional must charge $900 GST on a $10,000 service. The client pays $10,900 total; the business remits $900 (less input credits) to IRAS.
54.50 / 1.09 = 50.00
When a price tag includes GST, divide by 1.09 to find the pre-GST net. The $4.50 GST is collected by the retailer and remitted to IRAS.
Zero-rated but still GST-registered business claims input tax
Exports are zero-rated. The exporter charges no GST but can reclaim input GST paid on raw materials and services used to produce the exported goods.
Residential rent is GST-exempt
Residential rental is exempt from GST. Unlike zero-rated, the landlord cannot claim input GST on property renovation or maintenance costs as input tax credits.

Frequently Asked Questions
▾
What is Singapore GST and how does it work?
Singapore's Goods and Services Tax (GST) is a broad-based consumption tax on the import of goods and the supply of goods and services. The GST rate increased from 8% to 9% on January 1, 2024 (previously 7% until 2023, then 8% in 2023). GST-inclusive price calculation: GST-inclusive = price × 1.09. A $100 item costs $109 with GST. Extracting GST from an inclusive price: GST amount = inclusive price × 9/109. For a $109 item: GST = $109 × 9/109 = $9. Registration: businesses with annual taxable turnover exceeding $1 million must register for GST. Voluntary registration is available for smaller businesses (allows claiming input tax credits). GST-registered businesses charge GST on their sales (output tax) and can claim back GST paid on business purchases (input tax). The difference is remitted to IRAS quarterly. Exempt supplies (no GST charged, no input tax claimable): financial services, sale and lease of residential properties, and import/supply of precious metals. Zero-rated supplies (0% GST but input tax claimable): export of goods and international services. This is why many Singapore businesses benefit from voluntary GST registration if they primarily serve international clients — they charge 0% GST but can reclaim all input GST on their expenses.
How does the GST Voucher scheme help offset GST costs for Singaporeans?
The GST Voucher (GSTV) scheme is a permanent government program to help lower-to-middle income Singaporeans offset GST expenses. Components (2024): Cash component: up to $500/year for Singaporeans aged 21+ with assessable income up to $34,000 and who don't own more than one property. Tiered: $500 (income ≤$22,000 and live in 1-3 room HDB), $250-$450 for others depending on income and property type. MediSave component: up to $450/year for Singaporeans aged 65+ with assessable income up to $34,000. U-Save (utilities rebate): $440-$760/year for HDB households, varying by flat type (more for smaller flats). Credited quarterly to the SP utilities account. Eligibility: must be a Singapore citizen. Income thresholds and property value limits apply. Annual Value (AV) of home must not exceed $25,000 (roughly equivalent to living in an HDB flat or modest private property). The GSTV scheme combined with other rebates means that for low-income households, the government transfers more than offset the GST they pay — effectively making Singapore's consumption tax progressive despite being a flat rate. Higher-income Singaporeans bear the full GST burden. Additional one-off Assurance Package measures were introduced alongside the GST rate increases to cushion the impact over 5 years.
How do I calculate the GST amount from a GST-inclusive price, or add GST to a net price?
To calculate the GST amount from a GST-inclusive price, divide the total by 1.09 (for 9% GST) and subtract the result from the total; for example, from S$109, the GST is S$109 - (S$109 / 1.09) = S$9. To add 9% GST to a net price, multiply the net price by 0.09; for instance, a S$100 item will have S$9 GST, making the total S$109.
What is the difference between zero-rated and exempt supplies under Singapore's GST regime?
Zero-rated supplies, such as international services and exports of goods, are subject to GST at 0%, allowing businesses to claim input GST paid on related purchases. Exempt supplies, including financial services (e.g., interest from bank deposits) and the sale/lease of residential properties, are not subject to GST, and businesses cannot claim input GST for these supplies.
When is a business legally required to register for GST in Singapore?
A business must compulsorily register for GST if its taxable turnover for the past 12 months exceeds S$1 million, or if it expects its taxable turnover to exceed S$1 million in the next 12 months. Businesses can also voluntarily register for GST, subject to approval from the Inland Revenue Authority of Singapore (IRAS).
Common Mistakes to Avoid
▾
- !Charging 9% GST on exempt supplies such as residential rent or financial services — this is a compliance error.
- !Forgetting to update pricing when the GST rate changed from 8% to 9% on 1 January 2024.
- !Displaying prices exclusive of GST in retail without clear indication, which is a consumer protection violation.
- !Not registering for GST when turnover exceeds $1M, leading to backdated GST liability and penalties.
- !Claiming input tax credits on expenses related to exempt supplies, which is not allowed under partial exemption rules.
Pro Tip
If you are a consumer checking whether a price includes GST, look for 'GST-inclusive' or the '+GST' notation on price tags and invoices. All prices advertised to consumers in Singapore must be GST-inclusive. If you see a price marked '+9% GST', the headline amount does not yet include tax.
Did you know?
Singapore's GST was introduced on 1 April 1994 at a rate of just 3%. It has risen gradually over 30 years to the current 9%. Despite the increases, Singapore still has one of the lowest GST rates among developed economies — far below the EU average VAT of around 21% — and the government offsets the impact on lower-income households through permanent GST Voucher cash payouts.
