Starting a new company in Singapore means getting your legal and tax matters in order early. One key part of this is GST registration. If you’re not sure how it works or where to start, you’re in the right place.
In this guide, you’ll find simple steps to get through the process. You’ll also learn what documents to prepare, how to check if you need to register, and what to do once you’re done.
Let’s begin with the basics.
What Is GST?
GST stands for Goods and Services Tax. It is a tax on most goods and services sold in Singapore. If your company is GST-registered, you must charge GST on your sales and submit returns to the tax authority.
The current GST rate is 9%. Once you register, this is the rate you apply to your taxable sales.
Not every business must register. You only need to do so when your yearly revenue crosses a certain amount.
When Must You Register for GST?
You must register in two cases:
1. Past revenue has crossed S$1 million
If your taxable turnover in the last 12 months was more than S$1 million, you need to register. You have 30 days to do this once you cross the mark.
2. You expect to cross S$1 million soon
If you are sure your sales will go over S$1 million in the next 12 months, you must register early. You may have signed contracts or orders that prove this. IRAS will ask for documents to support your estimate.
There is also a third option — voluntary registration. Some companies choose to register early. This lets them claim GST on business expenses. However, you must commit to staying registered for at least two years.
Let’s look closer at the GST registration requirements.
What Do You Need to Apply?
Before you start the process, make sure you have:
- A registered company in Singapore
- Access to CorpPass (you use this to log in to IRAS)
- Proof of income (past or expected)
- Invoices, contracts, or agreements
- Tenancy papers, if any
If you are registering by choice, IRAS may ask you to take an e-learning course on GST. This helps ensure you understand what’s expected of you.
Now you’re ready to go through the steps.
How to Register for GST in Singapore
Step 1: Check Your Sales
Add up your total taxable sales over the past 12 months. If it’s above S$1 million, you must register. If not, you can still choose to do so.
You can check this monthly or use IRAS’s online calculator.
Step 2: Log in Using CorpPass
Go to myTax Portal. You need a CorpPass account to enter. If you don’t have one, set it up through the CorpPass website.
Make sure the person applying has permission to act for the business.
Step 3: Get Your Documents Ready
This includes:
- Income records (past and future)
- Sales or service contracts
- Invoices or bills
- Office lease agreements
If IRAS needs more documents, they’ll ask after you submit the form.
Step 4: Fill in the Application
Once logged in, go to “Register for GST”. Fill in the form and upload your documents. Check your company details before submitting.
For voluntary applications, you’ll need to confirm that you understand the terms and agree to remain registered for two years.
Step 5: Wait for Approval
It takes about 10 working days to hear back. If IRAS needs more details, they will contact you. You can also track the progress in myTax Portal.
Once approved, you’ll get a confirmation letter. This will tell you your GST number and your effective start date.
What To Do After Registration
Now that you’re registered, there are a few things you must do.
Update Your Invoices
Your GST number must be printed on all invoices. You also need to charge GST on your sales from the start date given by IRAS.
File Your Returns
You will need to file GST returns, usually every quarter. This tells IRAS how much GST you’ve collected and spent. You must do this on time. If not, you could face a fine.
Keep Good Records
Keep all invoices, bills, and statements for five years. IRAS may ask to see them during an audit.
GST Registration for Small Business in Singapore
If you run a small company, you may wonder if it’s worth registering. You might not meet the income limit, but Company GST Registration Singapore can still help.
For example, you can claim back GST on things like laptops, office rent, and other supplies. This can lower your business costs. It also adds trust when dealing with larger companies, especially those that are GST-registered themselves.
But do think about the extra work. You’ll need to keep better records, file returns on time, and follow the rules closely.
Can You Cancel Your Registration?
Yes, but only in some cases.
If your income drops or you close the business, you can ask IRAS to cancel your registration. You must clear any GST due before you do so.
To apply, go to myTax Portal and follow the instructions. You’ll receive a notice once it’s approved.
Tips to Keep Things Smooth
Here are a few simple tips:
- Watch your revenue. Check monthly if you’re close to S$1 million
- Store your records well. Keep digital copies for easy access
- Use good accounting software. It helps you track GST and file returns on time
- Don’t guess. If in doubt, ask IRAS or a tax adviser
In Summary
GST registration is part of running a business in Singapore. If your income is high enough, it’s not a choice — it’s the law. But even if you’re just starting out, registering early could give you a few extra benefits.
Once you register, make sure you charge GST properly, file your returns, and keep clear records. This keeps your business compliant and helps you avoid problems later.
Understanding the process makes things easier. Whether you’re applying by law or by choice, the key is to prepare well and stay on track.
