Goods and Services Tax (GST) is Singapore's broad-based consumption tax levied on the supply of goods and services. Understanding when a business must register is crucial because registration triggers ongoing compliance duties, including periodic filing, payment, and record‑keeping.
This guide breaks down the statutory turnover threshold, how taxable turnover is measured, exemptions, the registration process with the Inland Revenue Authority of Singapore (IRAS), and the consequences of non‑compliance, helping businesses stay on the right side of the law.
Quick Answer: A Singapore business is required to register for GST when its taxable turnover exceeds S$1 million in any 12‑month period, or if it voluntarily opts in. Certain businesses, such as those providing only exempt supplies, are excluded.
Key Takeaways
- Mandatory registration triggers at S$1 million taxable turnover in any 12‑month period.
- Taxable turnover includes all taxable supplies, excluding exempt and zero‑rated sales.
- Registration is done online via IRAS; typical processing takes 2‑4 weeks.
- Late registration or non‑compliance can attract penalties up to 200% of tax due.
- Businesses can apply for deregistration if turnover falls below S$500,000 for two consecutive years.
What is Goods and Services Tax (GST) in Singapore?
Quick Answer: GST is a broad-based consumption tax, currently set at 8% (as of 2024), imposed on the supply of most goods and services in Singapore.
GST was introduced under the Goods and Services Tax Act (Cap. 117) on 1 January 1994. The Act defines a “taxable supply” as any supply of goods, services, or the import of goods made in Singapore, unless specifically exempted or zero‑rated. Registered persons must charge GST on their taxable supplies, remit the net amount to the Inland Revenue Authority of Singapore (IRAS), and file periodic returns. The tax is ultimately borne by the end consumer, not the supplier.
Who is considered a taxable person under Singapore GST law?
Quick Answer: A taxable person is any individual, partnership, corporation, or entity that carries on a business in Singapore and makes taxable supplies.
Section 10 of the GST Act defines a “taxable person” as a person who, in the ordinary course of business, makes taxable supplies of goods or services, or imports goods, and is either required to be registered or has voluntarily registered. The definition includes Singapore‑incorporated companies, foreign entities with a Singapore place of business, and partnerships. Persons making only exempt supplies are not taxable persons, but may still be required to register if their turnover exceeds the threshold.
What is the S$1 million turnover threshold for mandatory GST registration?
Quick Answer: Businesses with a projected or actual taxable turnover of S$1 million or more in any 12‑month period must register for GST.
Section 13(1) of the GST Act sets the mandatory registration threshold at S$1 million of taxable turnover. “Taxable turnover” includes all taxable supplies made in Singapore, excluding exempt supplies, but includes zero‑rated supplies. The threshold is assessed on a rolling 12‑month basis; if a business exceeds it at any point, registration must occur within 30 days of crossing the limit. IRAS may also require registration based on reasonable estimates of future turnover.
How is “taxable turnover” calculated for GST registration purposes?
Quick Answer: Taxable turnover is the total value of all taxable supplies (including zero‑rated) made in Singapore, measured on a cash or accrual basis, minus any exempt supplies.
The IRAS Guidance Note clarifies that taxable turnover comprises the sum of (i) taxable supplies of goods and services, (ii) zero‑rated supplies, and (iii) imports of goods, measured at the time of supply. The calculation may be on a cash basis (when payment is received) or accrual basis (when invoice is issued), provided the method is consistently applied. Exempt supplies, such as most financial services, are excluded. Adjustments are made for discounts, returns, and bad debts.
Do startups and newly incorporated companies have a different registration timeline?
Quick Answer: No, startups are subject to the same 30‑day registration deadline once they exceed the S$1 million threshold, but they may apply voluntarily earlier.
Section 13(1) applies equally to newly incorporated entities. If a startup’s projected taxable turnover for the next 12 months is expected to exceed S$1 million, it must register within 30 days of that estimate becoming known. IRAS allows voluntary registration before the threshold is met, which can be advantageous for input tax recovery. Failure to register on time may result in penalties under Section 71 of the GST Act.
What are the filing and payment obligations after GST registration?
Quick Answer: Registered persons must file GST returns either quarterly or monthly and pay the net GST due within one month of the return due date.
Under Section 22 of the GST Act, a GST‑registered person must submit a GST return for each accounting period (normally quarterly) using IRAS’s online portal. The return must disclose total taxable supplies, input tax claimed, and net GST payable. Payment of the net amount is due within one month after the return filing deadline. Late filing or payment attracts penalties of up to 10% of the tax due and interest under Section 71.
Which supplies are exempt or zero‑rated under Singapore GST?
Quick Answer: Exempt supplies include most financial services and the sale of residential properties; zero‑rated supplies include exports, international services, and most public transport.
Section 9 of the GST Act lists exempt supplies such as (i) the provision of credit, (ii) the issue of securities, and (iii) the sale and lease of residential properties. Zero‑rated supplies, defined in Section 9(2), include (i) export of goods, (ii) international services, (iii) the supply of imported goods for export, and (iv) public transport services. Zero‑rated supplies are taxable but at 0%, allowing input tax recovery, whereas exempt supplies do not permit input tax claims.
How do you apply for GST registration with the IRAS?
Quick Answer: Registration is submitted online via IRAS’s Business Registration Portal (BizFile+) using the GST Registration Form (GST‑01).
The applicant logs into BizFile+, selects “GST Registration,” and completes Form GST‑01, providing details of the business, projected taxable turnover, and accounting period. Supporting documents may include the Certificate of Incorporation, latest financial statements, and a copy of the business’s tax identification number. IRAS may request additional information under Section 13(2). Upon approval, a GST registration number is issued and the entity must commence charging GST from the effective date.
What is the typical processing time for a GST registration application?
Quick Answer: IRAS usually processes a GST registration within 7 business days, though complex cases may take longer.
IRAS’s Service Standards state that straightforward applications submitted electronically are reviewed within five to seven business days. If additional information is required, the timeline extends by the period needed to obtain the documents, typically an additional 5‑10 days. Applicants receive an electronic acknowledgement and, upon approval, a GST registration number via email. Delays may arise where the applicant’s turnover estimate is contested or where the business structure is intricate.
When must a newly registered business submit its first GST return?
Quick Answer: The first GST return is due by the filing deadline of the first accounting period, usually one month after the end of that period.
Upon registration, IRAS assigns the business an accounting period (normally quarterly). The first return must cover the period from the effective registration date to the end of the first accounting period. The return filing deadline is the 30th day of the month following the period end, and payment is due on the same day. If the registration date falls mid‑quarter, the first period may be shortened, but the filing deadline remains one month after the period’s close.
Does a foreign company with a Singapore branch need to register for GST?
Quick Answer: Yes, if the branch’s annual taxable turnover in Singapore exceeds S$1 million, registration is compulsory; otherwise registration is optional.
Under the Goods and Services Tax Act (Cap 117A) s13(1), any person carrying on a business in Singapore with taxable supplies exceeding the S$1 million threshold in the preceding 12 months must register. A foreign company that operates a Singapore‑registered branch is deemed a “person” carrying on business in Singapore, so the same threshold applies. If the branch only makes exempt supplies (e.g., financial services) it is not required to register, even if turnover is higher.
Are there special GST rules for businesses that make only digital services to overseas customers?
Quick Answer: Digital services supplied to overseas consumers are zero‑rated, so GST is not payable, but registration may still be required if the provider exceeds the turnover threshold.
Section 16(2) of the GST Act treats supplies where the “place of supply” is outside Singapore as zero‑rated. IRAS guidance confirms that B2C digital services to non‑GST‑registered overseas customers fall within this rule. Consequently, the supply attracts a 0 % rate and does not create a GST liability. However, if the provider has a Singapore presence and its taxable turnover (including other supplies) exceeds S$1 million, compulsory registration under s13 still applies, with the overseas digital services reported at 0 %.
What exemptions exist for businesses with low turnover or specific industries?
Quick Answer: Businesses with taxable turnover below S$1 million are exempt from compulsory registration, and certain sectors such as financial services, residential property sales, and government services are statutorily exempt from GST.
Section 13(1) sets the S$1 million threshold; entities below it are not required to register, though they may elect voluntary registration under s14. Schedule 2 of the GST Act lists exempt supplies, including most financial services, the sale or lease of residential properties, and supplies by the Singapore government. Exempt supplies are not subject to GST and are excluded from the turnover calculation for registration purposes, even if the entity’s overall revenue exceeds the threshold.
Can a business deregister from GST, and under what conditions?
Quick Answer: Yes; a GST‑registered business may apply to deregister if its taxable turnover falls below S$1 million for two consecutive years or if it ceases to make taxable supplies.
Section 24 of the GST Act governs deregistration. The applicant must satisfy one of the following: (a) taxable turnover below the S$1 million threshold for two successive 12‑month periods, (b) cessation of all business activities, or (c) a change in status such that the entity is no longer a “person” carrying on business in Singapore. The business must file Form GST44, settle any outstanding GST, penalties, and GST on assets, and obtain IRAS clearance before the deregistration takes effect.
How can a business appeal a GST registration decision or penalty?
Quick Answer: An objection must be lodged with IRAS within 30 days of the decision, and if the objection is rejected, the matter can be appealed to the Singapore Tax Appeals Tribunal (STAT) within another 30 days.
Section 27(1) of the GST Act gives a taxpayer the right to object to an assessment or penalty. The objection must be in writing and filed within 30 days of the notice. If IRAS upholds the original decision, the taxpayer may appeal to STAT under s28(1) within 30 days of the objection decision. The Tribunal conducts a de novo review; its decision is final, subject only to limited judicial review on points of law.
What documents and information are needed to prepare a successful GST registration application?
Quick Answer: The application requires the completed GST registration form (Form GST F) together with corporate identification, business activity details, projected taxable turnover, and supporting evidence such as contracts or invoices.
IRAS requires: (i) Form GST F, (ii) a certified copy of the Certificate of Incorporation and latest Business Profile from ACRA, (iii) identification documents of directors/authorized signatories, (iv) a clear description of goods or services to be supplied, (v) an estimate of taxable turnover for the next 12 months, (vi) bank account details, and (vii) any relevant licences (e.g., telecom licence for digital services). Accurate turnover projections and detailed supply descriptions are critical to avoid delays or a request for additional information.
Practical Steps & Evidence Checklist
To comply with Singapore’s Goods and Services Tax (GST) regime, businesses must follow a clear sequence of actions and keep specific evidence to support their registration and ongoing compliance. The checklist below outlines the essential steps and the documentation you should gather.
- Step 1: Assess Your Turnover – Calculate your annual taxable turnover (including all taxable supplies and any exempt supplies that are not included in the threshold). If the turnover exceeds SGD 1 million, registration is mandatory; if it is below, voluntary registration is optional.
- Step 2: Gather Required Documents – Prepare the following evidence: a copy of your business registration certificate, bank statements, invoices issued, and proof of ownership or lease of premises. For foreign entities, include a valid business registration in the country of incorporation.
- Step 3: Register Online via the IRAS Portal – Log in to the IRAS e‑services portal, complete the GST registration form, and upload the supporting documents. Ensure that your contact details and business address are accurate.
- Step 4: Maintain Accurate Records – Keep all sales invoices, purchase invoices, and receipts for at least five years. Use a reliable accounting system that can generate GST‑compliant reports.
- Step 5: File GST Returns and Pay Tax – Submit your GST returns on a quarterly basis (or monthly if required) and remit the net GST payable to IRAS by the due dates. Monitor your account for any adjustments or penalties.

How do I cancel my GST registration?
Submit a written request to IRAS, either online or by mail, stating your intention to deregister. IRAS will review the request and, if approved, issue a deregistration certificate. Ensure all outstanding returns and tax liabilities are settled before cancellation.
Conclusion
Singapore’s GST regime imposes a clear threshold for mandatory registration, but voluntary registration offers strategic benefits such as input tax recovery and enhanced business credibility. Compliance requires diligent record‑keeping, timely filing, and payment of tax liabilities. Failure to meet these obligations can lead to significant penalties and reputational damage.
Businesses should assess their turnover, consider voluntary registration if advantageous, and maintain robust accounting systems. Engaging a qualified tax professional or solicitor can help navigate the registration process, ensure ongoing compliance, and mitigate risks associated with GST obligations.
