Are digital receipts valid for GST in Singapore?

Yes — digital receipts are valid for GST in Singapore if they carry the right details and are kept properly. Here’s what IRAS expects from merchants.

Short answer: yes, if you keep them properly

Digital receipts are valid for GST in Singapore. IRAS does not require a receipt or tax invoice to be printed on paper — what matters is that the document contains the required details, and that you keep a proper record of it for at least five years in a form that can be read and checked.

So if you’re a café or shop owner wondering whether going paperless will cause you problems at tax time: the format isn’t the issue. The record-keeping is. Get that part right and a digital receipt stands up exactly the same way a printed one does.

Here’s what that actually means day to day.

Receipt, simplified tax invoice, tax invoice — what’s the difference?

This trips up a lot of merchants, so let’s define the terms plainly.

• A receipt is proof that a customer paid you. Every business needs to be able to account for its sales.
• A tax invoice is a GST document. If you’re GST-registered and you make a standard-rated supply to a GST-registered customer, they need a tax invoice to claim their input tax. It has to carry specific particulars — the words “tax invoice”, your business name and address, your GST registration number, the customer’s details, a description of what was sold, and the GST amount.
• A simplified tax invoice is the shorter version many retail and F&B businesses use for smaller transactions. It leaves out the customer’s details but still needs your GST registration number and the amounts shown clearly.

Most walk-in F&B and retail sales fall into the third bucket. You are not required to issue a full tax invoice to a customer who isn’t GST-registered — though many will still ask for one if they’re claiming an expense at work.

None of these definitions mention paper. A simplified tax invoice delivered to a customer’s phone is still a simplified tax invoice, provided the required information is on it.

What IRAS expects if you keep records electronically

Four practical points worth knowing:

• Five years. Business and accounting records, including source documents, must be kept for at least five years.
• Readable. Electronic records have to be stored so they can be produced in human-readable form if IRAS asks to verify your figures.
• No physical copy needed. If your source documents are kept electronically, you don’t need to also keep paper copies for tax purposes.
• Don’t double up. If you’ve issued a customer an electronic tax invoice, don’t also hand them a paper one for the same sale — or if you must, invalidate one of them. Two live copies of the same tax invoice creates a risk of the same input tax being claimed twice.

There’s a small irony in that first point. IRAS has long advised businesses that keep thermal paper receipts to photocopy them, because thermal print fades over time. A receipt that’s blank by year three isn’t much of a record. Digital records don’t have that problem.

Requirements do get updated, so verify current rules and thresholds with IRAS before you change how you issue or store anything.

One thing not to confuse: InvoiceNow

You may have read that GST-registered businesses will need to submit invoice data to IRAS through InvoiceNow, Singapore’s national e-invoicing network, with the requirement being extended to all GST-registered businesses in phases.

That’s a separate obligation. InvoiceNow is about reporting invoice data to IRAS through an accredited solution. It is not a rule about what you hand your customer at the counter, and it doesn’t stop you issuing a digital receipt today. Check where your business sits in the rollout schedule directly with IRAS.

What this means if you’re thinking of going paperless

For a shop or café, the compliance question usually isn’t the real blocker. The real blocker is workflow: will the switch slow down the queue, will staff have to learn something new, and does it play nicely with the POS you already have?

That’s the practical case for handling receipts at the point of sale rather than after it. With NFC digital receipts on the counter, the customer taps their phone and the itemised receipt lands on their device — no app to download, no email address to type out, no QR code to squint at. Your POS keeps doing what it does; the receipt just stops being printed.

What that removes from your week:

• Thermal roll cost and the reorder trip
• Printer jams and fading print in the middle of a lunch rush
• A pile of paper that, being thermal, generally can’t go in the recycling bin
• Customers asking for a copy of a receipt they’ve already lost

And what it adds: a clean, itemised digital record of the sale that’s readable years later, which is exactly what good record-keeping asks for.

If you want the mechanics of how tap-to-receive actually works at a counter, we covered that in what NFC digital receipts are and why Singapore shops are switching.

Traceipt costs S$29.99 per month per terminal, or S$329.89 a year on the annual plan (one month free), and the Pad is included, so there is no upfront cost.

Questions people ask

Do I still need to print a receipt if the customer asks for one?

You can — just avoid having both a paper and an electronic version of the same tax invoice in circulation, or invalidate one of them.

Is a digital receipt enough for my customer to claim GST at their company?

If they’re GST-registered and the document carries the required tax invoice particulars, yes — the delivery format isn’t what determines validity.

How long do I need to keep digital receipts?

At least five years, stored so the records can be produced in readable form for verification. Confirm current requirements with IRAS.
