This guide is for businesses that charge, collect, or need to register for GST. It covers the 9% GST rate, the S$1 million registration threshold, how to register, how to file, and how to check whether a business is GST-registered. It does not cover the GST Voucher scheme — that is a separate government programme for eligible households, unrelated to business tax registration.
What is GST?
GST — Goods and Services Tax — is a broad-based consumption tax levied on the supply of goods and services in Singapore, as well as on the importation of goods. Administered by the Inland Revenue Authority of Singapore (IRAS), GST is charged by GST-registered businesses on taxable supplies and collected on behalf of the government. The current rate is 9%, applied to the pre-tax sale price. GST-registered businesses remit the tax collected to IRAS, typically on a quarterly basis, and may claim input tax credits on GST paid on their own business purchases.
GST is broadly equivalent to the Value Added Tax (VAT) system used in the UK, EU, and Australia — a multi-stage tax that is ultimately borne by the end consumer, not the business.
GST rate in Singapore (9%)
Singapore’s GST rate is 9%, effective from 1 January 2024. This was the second and final step of a phased GST rate increase announced in Budget 2022:
Period | GST rate |
|---|---|
Before 1 January 2023 | 7% |
1 January 2023 – 31 December 2023 | 8% |
1 January 2024 onward | 9% |
The 9% rate applies to all standard-rated supplies. Certain supplies are zero-rated (GST charged at 0%), including most exports of goods and international services. Certain other supplies are exempt (no GST charged and no input tax credit claimable), primarily financial services and residential property.
Worked example — calculating GST:
Sale price (before GST) | S$100.00 |
GST at 9% | S$9.00 |
Total charged to customer | S$109.00 |
When pricing products or services, you have two options: quote prices exclusive of GST (price + GST stated separately) or inclusive of GST (the listed price already includes the 9% component). IRAS requires that if you advertise GST-inclusive prices, the GST amount must still be separately identifiable on the tax invoice.

GST registration threshold & how to register
Mandatory registration threshold: S$1 million
A Singapore business must register for GST if its annual taxable turnover exceeds S$1 million (or is expected to do so in the next 12 months). Taxable turnover includes sales of all standard-rated and zero-rated supplies — exempt supplies (such as financial services or residential property rental) are not counted.
There are two registration triggers under IRAS rules:
Retrospective basis: At the end of any calendar year, if your taxable turnover for that calendar year exceeded S$1 million, you must register within 30 days of the year-end.
Prospective basis: At any point during the year, if there are reasonable grounds to believe that your taxable turnover in the next 12 months will exceed S$1 million, you must register within 30 days of forming that belief.
Voluntary registration
Businesses with turnover below S$1 million can voluntarily register for GST. This is advantageous when you incur significant GST on your business inputs (purchases, overhead, capital expenditure) and want to claim those input tax credits. Voluntarily registered businesses must remain registered for at least two years.
How to register for GST
GST registration is handled through the IRAS myTax Portal at mytax.iras.gov.sg:
Log in to myTax Portal using your CorpPass (for companies) or SingPass (for sole proprietors and partnerships)
Navigate to GST → Register for GST
Complete the application — provide your business UEN, effective registration date, expected turnover, and details of your business activities
Upload supporting documents where required (financial statements, contracts, or invoices supporting your turnover projection)
Submit and await IRAS approval — IRAS typically processes straightforward applications within 10 working days
Once registered, you will receive a GST registration number (a 9-digit number starting with a letter or “M”). This number must appear on all your tax invoices.
Source: IRAS — Registering for GST/gst-registration-deregistration/do-i-need-to-register-for-gst)
GST registration check — how to verify a business
A GST registration check lets you confirm whether a business is currently registered for GST in Singapore. This is useful when:
You receive a tax invoice from a supplier and want to verify their registration is genuine before claiming input tax credits
You are a buyer engaging a vendor and want to confirm their GST status
You need to validate a GST number provided to you
How to do a GST registration check:
Go to mytax.iras.gov.sg
Select GST from the top navigation
Click Search for GST-registered businesses
Enter the business name, UEN, or GST registration number
The portal will confirm the business’s GST registration status and display the registered GST number if active
The search is free, requires no login, and returns results in real time. The IRAS directory is the authoritative source — third-party GST lookup tools are not official and may be out of date.
What to look for in a valid tax invoice:
A valid GST tax invoice issued by a GST-registered business must include:
The words “Tax Invoice”
The supplier’s GST registration number
The date of supply
A description of the goods or services
The total amount payable excluding GST, the GST rate, the GST amount, and the total amount payable including GST
If a supplier cannot provide a valid tax invoice, you cannot claim the input tax credit — regardless of whether GST was charged.
Charging, collecting & filing GST
Charging GST on sales
Once registered, you are required to charge GST on all standard-rated taxable supplies. You issue a tax invoice to business customers (who may claim input tax credit) or a simplified tax invoice for supplies under S$1,000 to consumers. The tax invoice must show the GST amount and your registration number.
Businesses that charge customers GST before receiving their GST registration number are at risk of IRAS penalties — do not charge GST until your registration is confirmed.
Filing and paying GST
Most GST-registered businesses file quarterly — IRAS assigns a filing frequency (monthly, quarterly) based on your business profile. Filing is done via myTax Portal.
For each GST return (Form GST F5), you report:
Output tax: GST collected on your sales
Input tax: GST paid on your business purchases (claimable as a credit)
Net GST: The difference — if output tax exceeds input tax, you pay the difference to IRAS; if input tax exceeds output tax, you may claim a refund
GST returns and payment are due one month after the end of each accounting period. Late filing and payment attract penalties.
Record-keeping
IRAS requires GST-registered businesses to maintain all GST records for a minimum of five years. This includes tax invoices issued and received, import documents, and accounting records.
How HitPay helps with GST-inclusive pricing & invoicing
Managing GST compliance becomes operationally easier when your payment and invoicing systems handle the accounting automatically.
HitPay Invoicing supports itemised tax lines on invoices — you can configure a GST line at 9% that is applied automatically to each invoice. Invoices clearly display the pre-GST amount, the GST amount, and the total payable — matching the format required for IRAS-compliant tax invoices. Customers pay directly from the invoice via a hosted checkout that accepts PayNow, cards, GrabPay, and more.
Multi-currency invoicing: If you invoice overseas customers for zero-rated supplies, HitPay supports invoicing in over 150 currencies — you control whether GST is applied, at what rate, and how it is displayed.
Accounting integrations: HitPay syncs directly with Xero and QuickBooks — two of the most widely used accounting platforms for Singapore SMEs. Each transaction is mapped to the correct account code and tax treatment automatically, reducing manual reconciliation before GST filing.
Payment links with tax calculation: For one-off sales via payment link, HitPay supports price-inclusive and price-exclusive tax display — so the amount your customer sees and pays always reflects the correct GST position.
