Singapore operates on a strict, self-assessed tax framework managed by the Inland Revenue Authority of Singapore (IRAS). As a Singapore business entity owner, charging GST incorrectly or failing to collect it when legally required can result in steep financial penalties and backdated tax liabilities.
To remain compliant, your business must evaluate every transaction against specific statutory criteria.
Core Rules for Charging GST
Your business is only authorized and required to charge GST if the transaction meets four specific legal conditions set by IRAS:
- GST-Registered Status: Your entity must be actively registered for GST. Non-registered businesses are strictly prohibited from charging or collecting GST.
- Taxable Supply: The transaction must involve a taxable supply of goods or services.
- Local Geographical Scope: The supply must be made within the geographical boundaries of Singapore.
- Business Furtherance: The transaction must be made in the course or furtherance of your business activities.
Important Warning: If your business is not GST-registered but includes GST on invoices, you are violating IRAS regulations. All wrongfully collected tax must be paid to IRAS immediately, and your business may face prosecutorial penalties.
Breakdown of Supply Types and GST Rates
Not all business transactions are taxed equally. IRAS categorizes supplies into four distinct categories, which dictate the exact rate of tax you must apply.
Standard-Rated Supplies (9% GST, effective from 1 January 2024)
This is the default tax bracket for most domestic transactions. If you sell goods or provide services to customers inside Singapore, you must apply the prevailing standard rate.
- Applicable Rate: 9% (Effective 1 January 2024)
- Examples: Local retail sales, domestic commercial cleanings, local consulting services, and legal advisory services provided to clients residing in Singapore.
Zero-Rated Supplies (0% GST)
Zero-rated supplies are technically taxable, but the tax rate applied is legally set to 0%. This category allows your business to maintain compliance while remaining competitive internationally.
- Applicable Rate: 0%
- Examples: International freight services, provision of services to overseas clients (qualifying as international services under Section 21(3) of the GST Act), and the direct export of physical cargo.
- IRAS Documentation Rule: To apply 0% GST, you must obtain and maintain valid export documents (e.g., Bills of Lading, Airway Bills) within 60 days from the time of supply. Failing to produce this proof requires your business to account for the standard 9% tax retrospectively.
Exempt Supplies (No GST Charged)
Exempt supplies fall completely outside the scope of taxable transactions. You do not charge GST on these sales, and you generally cannot claim input tax incurred on purchases used to make these supplies.
- Applicable Rate: Non-taxable
- Categories:
- Financial services (e.g., issue of debt securities, digital payment token transactions).
- The sale or lease of residential properties.
- The import and local supply of investment precious metals (IPM).
Out-of-Scope Supplies (No GST Charged)
These are transactions that do not fall within the scope of the Singapore Goods and Services Tax Act.
- Applicable Rate: Non-taxable
- Examples: Statutory fees paid to government bodies, or third-country sales where goods are shipped directly from one foreign country to another without entering Singapore’s customs territory.
Price Display and Invoice Compliance
If your business is GST-registered, you must adhere to clear public transparency and invoicing protocols mandated by IRAS.
1. Displaying GST-Inclusive Prices
Any price shown, quoted, or advertised to the general public must be inclusive of the prevailing 9% GST. You cannot display a price of S$100 and add 9% at the point of sale unless you operate in the food and beverage (F&B) or hospitality industries where service charges apply.
2. Issuing Valid Tax Invoices
You must issue a valid Tax Invoice for standard-rated transactions exceeding S$20. The invoice must clearly display your business name, address, tax registration number, the total GST amount, and separate lines distinguishing taxable items from non-taxable ones.
