GST and card payments in Singapore
This question comes up in every onboarding and it is almost always three questions wearing one coat: GST on what you sell, GST on what your provider charges you, and what your customer sees. They have different answers and different people who give them. Untangling which one you are asking is most of the work — and this page does that and then tells you who to ask, because the answer itself is not a payment provider's to give.
In short
- This page is not tax advice. IRAS and your accountant are the sources; this is a map of the question.
- Three separate questions get asked as one. Separate them first.
- Your settlement is not your revenue, and that is where most of the confusion starts.
- The provider fee and your own sales are two different GST positions.
- Get the treatment agreed with your accountant before the first quarter closes, not while filing.
The three questions inside the one question
When a merchant asks "how does GST work with card payments", they are asking one of these, and usually do not know which:
- "Do I charge GST on my sales?" — a question about your business and your registration status. It has nothing to do with how the customer pays. A GST-registered business charges GST whether the customer pays by card, by QR or in cash.
- "Is there GST on what my payment provider charges me?" — a question about a supply made to you, and about how you account for it as an input. Your provider's invoices and statements are the evidence; your accountant decides the treatment.
- "What does the customer see, and what goes on the receipt?" — a question about your own pricing and receipt practice, which you control.
Nearly every long conversation about "GST and card fees" is two people answering two different questions from that list. Ask which one before answering, including of yourself.
The thing that actually causes the confusion
What lands in your bank account is not what you sold. A settlement is a batch of transactions less whatever was deducted, arriving as a single credit. Your sales figure and your settlement figure are different numbers describing different things, and every GST question that goes wrong goes wrong here.
A merchant who reports the bank credit as revenue has understated their sales by the fees — which is a bookkeeping error before it is a tax one, and it compounds quietly across a quarter. The correct figure is the gross sales, with the fees handled separately as a cost. Which is exactly why the reporting matters:
- You need gross sales — what customers were charged, before anything was taken.
- You need the fees, as their own figure, with the provider's documentation behind them.
- You need to be able to tie a bank credit to a batch, so the two reconcile.
If your provider's reporting does not give you those three cleanly, that is a real problem and it is worth raising as one — see settlement and reconciliation.
What to ask your provider, and what to ask your accountant
Your payment provider can tell you
- What documentation you receive for the fees charged, in what form, and how often.
- Whether fees are deducted from settlement or invoiced separately — this changes what your books look like, and providers differ.
- Whether the entity billing you is a Singapore entity, which is a question your accountant will ask you and which you should not have to guess at.
- How to get a report showing gross sales and deductions separately for any period.
Only your accountant or IRAS can tell you
- Whether and when you must register for GST.
- How to treat the provider's charges in your return.
- What has to appear on your receipts and invoices.
- Anything specific to your structure — multiple entities, overseas parent, mixed supplies.
A payment provider that answers the second list is giving you tax advice it is not qualified to give, and you are the one who carries it. Ours will not, and that is not evasion — it is the correct answer.
Two things worth doing before the quarter closes
- Pull one month of settlement reporting and hand it to your accountant now. Not at filing time. What you want is them telling you the reports contain what they need, while there is still time to ask the provider for something different if they do not.
- Check what your receipts say. The receipt is the customer-facing half of this and it is the half a merchant controls completely. If your terminal or checkout prints something your accountant would change, changing it is a settings conversation, not a system change.
Both are half an hour, once. The alternative is discovering the gap during a filing period, which is the same work done at the worst possible time.
What this page deliberately does not say
No rate, no threshold, no treatment and no statement about what your particular position is. That is not modesty — Singapore GST rules change, they apply differently by business structure, and a payments company writing them down is creating a document somebody will rely on in a year when it is out of date. IRAS publishes the current rules and your accountant applies them to you.
What this page is for is making sure that when you have that conversation, you arrive with the right three questions separated and the right reports in hand.
Questions merchants ask
Is there GST on payment processing fees in Singapore?
That is a question about a supply made to your business, and the answer depends on your registration status and on the entity billing you — so it is one for your accountant and for IRAS, not for a payments company. What your provider can and should give you is clear documentation of what was charged, in what form, and how often, which is what your accountant needs in order to answer it.
Should I record the bank credit or the gross sales as my revenue?
Gross sales — what customers were actually charged — with fees handled separately as a cost. The bank credit is a batch of transactions less deductions, so recording it as revenue understates your sales by the fees. This is the single most common bookkeeping error in card acceptance.
Does GST change depending on whether the customer pays by card, QR or cash?
No. Whether you charge GST on a sale is a question about your business and its registration status, not about the payment method. How the customer paid changes your fees and your reconciliation, not your obligation on the sale.
Can Uniweb Pay tell me how to handle GST?
No, and no payment provider should. We can tell you what we charge, in what form you receive the documentation, whether fees come out of settlement, and how to pull a report showing gross sales and deductions separately. What to do with that in a return is for your accountant and IRAS.
What reporting should I ask for before speaking to my accountant?
One month showing gross sales, the deductions as their own figure, and enough detail to tie each bank credit to a batch. If a provider cannot produce that, the problem is the reporting rather than the tax question, and it is worth solving first.
