Understanding GST in Singapore

If you are a business owner or planning to start a business in Singapore, it is important to understand the basics of GST. GST stands for Goods and Services Tax, which is a broad-based consumption tax levied on nearly all supplies of goods and services in Singapore. In other countries, GST is known as Value-Added Tax or VAT.
Basics of GST
GST is charged at a rate of 7% on the supply of goods and services in Singapore. Registered businesses are required to charge GST on their taxable supplies and remit the GST collected to the Inland Revenue Authority of Singapore (IRAS) on a regular basis.
GST Registration
Businesses with an annual taxable turnover of more than SGD 1 million are required to register for GST. However, businesses with a turnover of less than SGD 1 million may also choose to register voluntarily. Once registered, businesses are required to charge GST on their taxable supplies and submit regular GST returns to IRAS.
GST Rates and Calculations
To calculate the GST amount, you can use the formula: GST amount = GST rate x GST exclusive amount. For example, if the GST rate is 7% and the GST exclusive amount is SGD 100, the GST amount would be SGD 7.
To calculate the GST inclusive amount, you can multiply the GST exclusive price by 1.07. For example, if the GST exclusive price is SGD 100, the GST inclusive price would be SGD 107.
If you need to calculate the GST exclusive amount from the GST inclusive price, you can use the reverse GST calculation formula: GST exclusive amount = GST inclusive amount / 1.07.
Overall, understanding GST in Singapore is crucial for any business owner. It is important to register for GST if required and to accurately calculate and remit the GST collected to IRAS. You can use a GST calculator to make the calculations easier and ensure accuracy.
Applying GST in Business Operations

If you’re a business owner in Singapore, you must register for the Goods and Services Tax (GST) if your taxable turnover exceeds SGD 1 million. Once you’ve registered, you’ll need to understand how to apply GST to your business operations.
GST on Imports and Exports
If you’re importing goods into Singapore, you’ll need to pay GST on the cost, insurance, and freight (CIF) value of the goods. You can claim input tax credit on the GST you paid on the import if you’re using the goods for your business.
If you’re exporting goods out of Singapore, you generally won’t need to charge GST. However, if you’re exporting services or digital products to overseas customers, you’ll need to charge GST if the customer is not registered for GST in their country.
Special GST Schemes
There are several special GST schemes available to businesses in Singapore. For example, the Tourist Refund Scheme allows tourists to claim a refund of the GST they paid on their purchases in Singapore. The Major Exporter Scheme allows qualifying businesses to pay GST on a quarterly basis instead of monthly.
Calculating GST for Specific Goods and Services
Calculating GST for specific goods and services can be complicated. Some goods and services are exempt from GST, while others are zero-rated. Financial services and precious metals are examples of goods and services that are exempt from GST.
It’s important to seek professional advice to ensure you’re applying GST correctly to your business operations. Keep accurate records of your GST-inclusive and GST-exclusive purchases and sales, as well as any input tax credit you’re claiming. This will make it easier to complete your GST return and claim any GST refunds you’re entitled to.
