In Singapore, the Goods and Services Tax (GST) is a consumption tax levied on the supply of goods and services and the import of goods. While businesses are only mandatorily required to register for GST when their taxable turnover exceeds S$1 million in the past 12 months, many small and growing businesses choose to register voluntarily.
This decision—known as voluntary GST registration—can offer both strategic advantages and compliance responsibilities. In this blog, we explore what voluntary GST registration is, its potential benefits and drawbacks, and whether your business should consider it.
What Is Voluntary GST Registration?
Voluntary GST registration is an option provided by the Inland Revenue Authority of Singapore (IRAS) that allows businesses not yet meeting the mandatory threshold of S$1 million in taxable turnover to register for Goods and Services Tax (GST) on their own accord. This means even if your business has not yet reached the revenue requirement, you can still opt to become GST-registered and operate under the same compliance framework as larger businesses.
Once voluntarily registered, your business is required to:
- Charge 9% GST (as of 2024) on all taxable goods and services sold or provided in Singapore.
- Issue tax invoices that reflect GST charges.
- Submit regular GST returns (usually on a quarterly basis) to IRAS.
- Pay GST collected from customers and claim input tax on qualifying business purchases.
This voluntary move can be strategic for certain businesses, particularly those looking to recover GST paid on expenses, enhance credibility with clients, or prepare for future growth.
Eligibility Requirements for Voluntary GST Registration
To qualify for voluntary GST registration, your business must meet several criteria set out by IRAS. These include:
Application via myTax Portal
The registration process is done online through IRAS’s myTax Portal. You’ll need to provide information about your business, your taxable supplies, and projected revenue.
Intent to Make Taxable Supplies
IRAS requires applicants to show that they are already making, or intend to make, taxable supplies in Singapore. These are supplies of goods or services that are subject to either standard-rated or zero-rated GST.
Compliance with GIRO Requirement
As part of the registration conditions, voluntarily registered businesses must be on GIRO (General Interbank Recurring Order) for GST payments and refunds. This facilitates timely payments and reduces administrative overhead.
Completion of an E-Learning Course
Directors, sole proprietors, or partners must complete a mandatory e-learning course on GST fundamentals provided by IRAS, which ensures that they understand the responsibilities and obligations that come with being GST-registered.
Note: This requirement may be waived if the business engages a registered GST filing agent or is managed by individuals with proven GST knowledge or experience.
Post-Registration Responsibilities
Once IRAS approves your application, your business becomes legally obligated to fulfill all GST-related duties, regardless of your turnover amount. This includes:
- Charging and collecting GST from customers.
- Filing GST returns accurately and on time.
- Keeping proper accounting records for at least five years.
- Complying with GST audit requirements if reviewed by IRAS.
Failure to meet these obligations may result in penalties, fines, or revocation of registration, so it’s crucial to understand what’s expected before registering voluntarily.
Who Should Consider Voluntary GST Registration?
Voluntary registration may be suitable for:
- Startups and SMEs expecting rapid growth that may cross the threshold soon.
- Exporters and zero-rated suppliers, as they can claim GST refunds on local purchases.
- Businesses with significant GST-paid purchases, such as in wholesale, manufacturing, or logistics.
- Companies working with GST-registered clients, who may prefer vendors that can issue GST invoices.
Benefits of Voluntary GST Registration
1. Input Tax Claims
One of the most compelling reasons to register for GST voluntarily is the ability to claim input tax on business purchases. This means you can recover the GST paid on goods and services used for your business operations—such as office rent, marketing services, professional fees, IT equipment, and software subscriptions. For businesses in sectors like retail, logistics, manufacturing, or professional services—where upfront and recurring costs are significant—this can lead to substantial savings. Over time, claiming input tax can improve your cash flow and reduce your net expenses.
2. Improved Business Credibility
Voluntarily registering for GST can enhance your business’s reputation and legitimacy. Many clients, particularly corporates, government bodies, and multinational companies, view GST registration as a mark of a structured and compliant business. It indicates that your company is established enough to interact within Singapore’s formal tax system and is possibly growing toward larger revenue brackets. This can instill confidence among potential partners, suppliers, and investors.
3. Client Preference
If you operate in a B2B (business-to-business) environment, your clients may be GST-registered themselves and prefer dealing with vendors who can issue valid tax invoices. This enables them to claim input tax on their end. In such cases, not being GST-registered could put you at a disadvantage, as clients may opt for suppliers who can help them with tax recovery. This is particularly relevant when bidding for tenders, supplying to GST-registered entities, or working with government-related projects where GST invoicing is a requirement.
4. Preparedness for Growth
Businesses that expect to exceed the S$1 million revenue threshold in the near future should consider registering early to avoid being caught unprepared. If you hit the threshold without having registered in time, you may face penalties for late registration and backdated tax liabilities. Voluntary registration allows you to get ahead of regulatory requirements, implement proper systems, and train staff to manage GST responsibilities smoothly before your business grows further.
Potential Drawbacks to Consider
1. Administrative Burden
With GST registration comes additional administrative work. Businesses are required to file GST returns—typically on a quarterly basis—and ensure that returns are accurate and submitted on time. You must also maintain detailed records of your sales, purchases, input and output tax, and tax invoices for at least five years, as per IRAS guidelines. This increases the need for bookkeeping accuracy and may require additional resources, such as hiring an accountant or investing in accounting software, to manage compliance.
2. Pricing Impact
When you become GST-registered, you must charge 9% GST (as of 2024) on your taxable supplies. This increases the final price paid by your customers, unless you decide to absorb the tax within your current pricing, which would reduce your profit margins. This price hike can be a competitive disadvantage if your target customers are not GST-registered and cannot claim input tax. In B2C (business-to-consumer) settings, where price sensitivity is high, this could affect sales or customer loyalty.
3. Ongoing Compliance Obligations
Voluntary registration is a commitment. Once registered, you must comply with all GST obligations—even if your business revenue remains below the mandatory threshold in the future. You cannot simply stop charging GST or ignore return filings. If you wish to stop being GST-registered, you must go through the formal deregistration process with IRAS, which includes showing that your business no longer makes or intends to make taxable supplies. This commitment means ongoing responsibility, which may not be suitable for very small businesses or solo entrepreneurs with limited capacity.
Should Your Business Register for GST Voluntarily?
Here are some questions to guide your decision:
- Are you planning to scale rapidly or enter contracts that will push you past the S$1 million mark soon?
- Do you purchase from GST-registered suppliers frequently and wish to recover the GST incurred?
- Are your customers GST-registered and able to claim input tax, reducing price sensitivity?
- Do you have accounting support to handle GST compliance, or are you willing to invest in it?
If the answers lean toward yes, voluntary GST registration could be a strategic move to improve cash flow, strengthen business relationships, and stay ahead of regulatory obligations.
Final Thoughts
Voluntary GST registration in Singapore is a proactive step that could offer tax recovery advantages and business credibility, but it comes with ongoing responsibilities. We recommend discussing your situation with a tax professional or corporate service provider to make a well-informed decision.
Frequently Asked Questions (FAQ)

Yes, there is no registration fee for applying for GST with IRAS. However, businesses may incur administrative costs for compliance, such as accounting support or GST software.
2. How long does it take to get approved for GST registration?
It typically takes around 10 working days for IRAS to process your application, provided all required documents and declarations are correctly submitted. Delays may occur if additional information is required.
3. Can I deregister from GST if I change my mind?
Yes, but you must submit a voluntary deregistration application to IRAS and meet the conditions for deregistration. Approval is subject to IRAS’ review, and you must remain compliant until officially deregistered.
4. Do I need to charge GST to overseas customers?
If you’re supplying goods exported overseas or providing international services, these may be zero-rated (0% GST). However, you must still report them in your GST returns.
