In Singapore, GST (Goods and Services Tax) registration becomes mandatory once your taxable turnover exceeds $1 million over a 12-month period. But what if your business hasn’t hit that threshold yet? Should you still consider registering voluntarily?
For some SMEs, voluntary registration can offer strategic benefits—but it’s not always the right move for every business. In this article, we’ll explore when it makes sense to register voluntarily, the risks involved, and how to decide what’s best for your company.

What Is Voluntary GST Registration?
Voluntary GST registration allows businesses below the $1 million turnover threshold to register for GST with IRAS. Once approved, you’ll need to charge GST on your sales, file regular GST returns, and meet the same compliance obligations as mandatory registrants.
When Voluntary Registration Makes Sense
Here are a few scenarios where voluntary registration could be a smart business decision:
1. Your Customers Are Mostly GST-Registered Businesses
If most of your clients are GST-registered, they can claim the GST you charge them—so becoming GST-registered won’t affect your competitiveness. Meanwhile, you can start claiming input tax on your business expenses, reducing your costs.
2. You Have Significant Start-up Costs or Imports
Businesses in early growth stages or those importing goods and services may benefit from claiming GST on large upfront costs, helping with cash flow and cost recovery.
3. You Want to Enhance Business Credibility
Being GST-registered may give the impression that your business is well-established and credible, especially when dealing with corporate clients, government tenders, or overseas partners.
4. You Plan to Cross $1M Turnover Soon
If your revenue is climbing steadily, registering early can help you avoid penalties for late registration and give you time to build up internal processes to handle GST compliance.
What Are the Risks of Voluntary Registration?
Before you apply, consider these downsides:
- More Compliance Requirements
You'll need to file GST returns quarterly (or monthly), maintain proper tax records, issue tax invoices, and meet IRAS deadlines—regardless of your business size.
- Pricing Impact for Non-GST Clients
If you serve consumers or small businesses who can’t claim GST, adding 9% to your pricing could make you less competitive.
- Minimum Registration Period
Voluntarily registered businesses are usually required to stay registered for at least two years, even if your business activity drops.
How to Decide?
Ask yourself:
Are most of my customers GST-registered?
Do I have large expenses or imports I could claim input tax on?
Am I prepared to handle the compliance and administrative workload?
Will GST registration impact my pricing competitiveness?
If the answer to most of these is yes, voluntary GST registration might benefit your
business.
