Singapore GST Rate 2026: What Businesses Must Know

Singapore’s GST rate is 9% in 2026. It’s been at 9% since 1 January 2024, when it rose from 8% as the second step of a two-stage increase, and there’s no further rate change currently announced. What matters for your business now isn’t the rate itself — it’s staying on top of registration thresholds, correct invoicing, and the mandatory e-invoicing rollout that’s reaching more GST-registered businesses this year.

This guide covers the current rate, who needs to register, and the compliance changes actually in motion for 2026.

TL;DR — Singapore GST in 2026

• The rate is 9%, unchanged since 1 January 2024, applied to most goods and services supplied in Singapore.
• Registration is compulsory once your taxable turnover exceeds S$1 million in any 12-month period (or is expected to).
• Voluntary registration is available below that threshold, but carries a minimum 2-year commitment.
• GST InvoiceNow is being phased in for all GST-registered businesses between 2028 and 2031 — new voluntary registrants already need it from 1 April 2026.
• File and pay on time — GST returns (Form F5) are due quarterly via IRAS’s myTax Portal; late filing triggers an automatic penalty.

What Is the Current GST Rate in Singapore?

The Goods and Services Tax (GST) rate in Singapore is 9%, applied to most goods and services supplied or imported into Singapore. GST is a consumption tax: businesses collect it from customers at the point of sale and remit it to the Inland Revenue Authority of Singapore (IRAS), which administers the tax.

The 9% rate took effect in two steps, both announced by the Ministry of Finance in 2022:

• 7% → 8%, effective 1 January 2023
• 8% → 9%, effective 1 January 2024

Since then, the rate has held at 9%, and IRAS has not signalled a further increase. Some goods and services are zero-rated (0%) — mainly exports and international services — while others, like most financial services and residential property sales, are exempt from GST entirely.

\Do You Need to Register for GST?

Registration is compulsory once your business’s taxable turnover exceeds S$1 million in a 12-month period, whether looking back (retrospective test) or expected going forward (prospective test). Below that threshold, registration is optional.

Voluntary registration makes sense for some businesses even under the threshold, because it lets you claim back GST paid on your own business expenses (input tax). The trade-off: once you register voluntarily, you’re committed to staying registered for at least 2 years, and you take on the full set of GST compliance obligations — charging GST correctly, filing on time, and now, in many cases, InvoiceNow.

The GST InvoiceNow Requirement: What’s Changing in 2026

GST InvoiceNow is IRAS’s move toward requiring GST-registered businesses to transmit invoice data directly to IRAS, rather than reporting it only in a quarterly return. It’s being rolled out in stages rather than all at once:

The practical impact for 2026: if you’re planning to register for GST voluntarily, InvoiceNow readiness isn’t optional — from 1 April 2026, IRAS can reject a voluntary registration application if InvoiceNow isn’t in place. If you’re already GST-registered under the compulsory threshold, you have until your assigned date between 2028 and 2031, but waiting until the deadline year to sort out your accounting system’s InvoiceNow connection is the kind of thing that becomes a rushed scramble.

Staying Compliant: Filing, Records, and Common Mistakes

GST-registered businesses must file GST returns (Form F5) quarterly through IRAS’s myTax Portal, even in periods with no GST to declare. Late filing triggers an automatic penalty, and consistent late or incorrect filing draws closer IRAS scrutiny.

The mistakes we see most often with SMEs:

• Charging the wrong rate on transitional invoices — supplies that straddle a rate change or a billing period need the correct rate applied based on when the goods or services were actually delivered, not just when the invoice was issued.
• Displaying GST-exclusive prices to consumers. Singapore requires GST-inclusive price display for goods and services offered to the public.
• Treating GST like a cost rather than a pass-through. For a GST-registered business, GST charged to customers isn’t revenue, and GST paid on business expenses is generally recoverable as input tax — but only with proper records.
• Not keeping records for the full retention period. Business and accounting records supporting GST declarations must be kept for at least 5 years.

How Grof Can Help

The GST rate itself stopped being the interesting question the moment it settled at 9% in January 2024. What actually catches SMEs out now is everything downstream of that rate — whether you’ve crossed the registration threshold without noticing, whether your invoicing system can handle InvoiceNow before IRAS requires it, and whether your quarterly filings are landing on time. Those are the things worth checking today, not the number itself.

If GST compliance is one more thing competing for your attention, Grof’s GST registration and filing services handle the registration decision, the quarterly filings, and the InvoiceNow transition, so it stops being something you have to track yourself.
