Free GST Invoice Generator for Singapore

This free GST invoice generator is set up for Singapore. It prints the title "Tax Invoice", adds your GST reg. no., applies GST at 9% and keeps every total exact to the smallest unit of Singapore Dollar (SGD). In Singapore only GST-registered businesses may issue a tax invoice, and it must show the GST registration number and the 9% GST amount.

Fill in your business, your client and the items; the invoice builds itself beside the form. Each line can carry its own rate, and the totals show the taxable value, each tax line and the grand total, followed by the amount in words. Special cases are covered too (zero-rated (0%) and exempt): pick the treatment and the legal wording is printed for you. Dates follow the local format (26/10/2026).

Nothing you type leaves your computer: drafts, saved clients and your invoice history stay in this browser, and the PDF is created on your device. Rates were last checked on 2026-10-26; tax rules change, so confirm anything unusual with your tax authority.

Frequently asked questions

What GST rates can I use for Singapore?

The generator offers 9%. These are starting values last checked on 2026-10-26. Singapore GST is 9% from 2024. Check iras.gov.sg before relying on it.

Do I need my GST reg. no. on the invoice?

Yes. A tax invoice should show your GST reg. no.. The generator checks the format and warns you if it looks wrong, but never blocks your download.

Can I enter prices that already include tax?

Yes. Choose "Including GST" and the generator works the tax back out of each price, so the total equals the prices you entered.

Is this a government e-invoice?

No. It creates a PDF invoice for you to send. Singapore does not require a government e-invoicing system for most small businesses, but check if that changes.

Where is my invoice data stored?

Only in your own browser. Nothing is uploaded, and the generator works offline after the first visit.
