Singapore GST for Freelancers: Registration, Rates, and Invoicing

Singapore’s Goods and Services Tax (GST) is a consumption tax on most goods and services. The rate increased from 8% to 9% on January 1, 2024. Here’s what freelancers operating in Singapore need to know.

Do You Need to Register for GST?

Mandatory registration: If your taxable turnover exceeds SGD 1 million in the past 12 months or is expected to exceed SGD 1 million in the next 12 months.

Voluntary registration: You can register voluntarily below the threshold. This lets you claim GST on business expenses. However, once registered, you must remain registered for at least 2 years.

Below threshold: If you’re under SGD 1 million, you’re not required to register and cannot charge GST.

The GST Rate

Zero-rated: GST applies at 0% — you can claim input GST on expenses. Examples: exports, international services.

Exempt: No GST applies and you cannot claim input GST on related expenses. Examples: financial services, residential property sales/rentals.

What’s Zero-Rated for Freelancers?

International services are zero-rated when:

• Services are provided to an overseas person
• Services are not directly connected with land or goods in Singapore
• Services are not specifically excluded

Practical rule: If your client is based outside Singapore and the work doesn’t relate to Singapore property or goods, your services are likely zero-rated.

What Goes on a GST Invoice?

A valid Singapore tax invoice must include:

1. The words “Tax Invoice”
2. Your business name and address
3. Your GST registration number (format: M1234567X)
4. Invoice date
5. Invoice number — unique sequential number
6. Client’s name and address
7. Description of services
8. Total amount excluding GST
9. GST rate (9%)
10. GST amount
11. Total amount including GST

For invoices under SGD 1,000: A simplified tax invoice is acceptable (less detail required).

Example Invoice Breakdown

Overseas Clients — Zero-Rating

When billing overseas clients:

Services: Website development
Net amount: SGD 8,000.00
GST: SGD 0.00 — Zero-rated international services (Section 21(3))
Total: SGD 8,000.00

Client: [Client Name], [Country]

You must keep records proving the client is overseas and the services qualify for zero-rating.

Input Tax Claims

Once GST-registered, you can claim GST paid on business expenses:

Claimable:

• Software subscriptions
• Equipment and hardware
• Professional services
• Office supplies

Not claimable:

• Private expenses
• Club membership fees
• Medical expenses (unless employment-related)
• Motor car expenses (with limited exceptions)

Filing GST Returns

• Filing frequency: Quarterly (some businesses may apply for monthly)
• Due date: Within 1 month after the end of each accounting period
• Platform: IRAS myTax Portal
• Payment: GST collected minus GST claimed

Example: You collected SGD 9,000 GST from clients this quarter. You paid SGD 1,500 GST on software and equipment. You remit SGD 7,500 to IRAS.

Common Mistakes

1. Late registration. If you exceed SGD 1 million and don’t register within 30 days, penalties apply.

2. Charging GST when not registered. You cannot charge GST without a valid registration number.

3. Wrong zero-rating. Not all international services qualify — services connected to Singapore land or goods are standard-rated.

4. Missing documentation. Keep records proving your client is overseas for zero-rated supplies.

Penalties

IRAS enforces penalties for non-compliance:

• Late registration: Up to SGD 10,000
• Late filing: SGD 200 immediately, escalating with continued delay
• Late payment: 5% penalty + interest at prevailing rate
• Incorrect returns: Penalties based on tax shortfall

Overseas Vendor Registration (OVR)

If you’re an overseas freelancer selling digital services to Singapore consumers (B2C), you may need to register under the Overseas Vendor Registration regime if your sales to Singapore customers exceed SGD 100,000 and your global turnover exceeds SGD 1 million.
