Frequently asked questions
What is the latest VAT invoice format in Sri Lanka?
The current tax-invoice format is Form 4A under Part I : Sec. (6) of the Gazette Extraordinary of the Democratic Socialist Republic of Sri Lanka dated 27.03.2026. It uses the supplier's and purchaser's TIN, date and place of supply, an item table, and total value of supply, VAT amount and total including VAT. This generator follows that layout.
What is the VAT rate in Sri Lanka?
Sri Lanka's standard VAT rate is 18%, effective from 1 January 2024. The generator defaults to 18% and the rate stays editable for zero-rated or exempt supplies.
Do I need a TIN on the tax invoice?
Yes. The gazetted Form 4A requires the supplier's TIN (Taxpayer Identification Number), and the purchaser's TIN where the purchaser is registered.
Is this VAT invoice generator free?
Yes, it is completely free with no sign-up. It runs entirely in your browser, so your details are never uploaded or stored.
How do I save the invoice as a PDF?
Click “Print / Save as PDF”, then choose “Save as PDF” as the destination in your browser's print dialog. The output is scoped to just the invoice sheet.
Is this official tax advice?
No. This is a free convenience tool. Always confirm current VAT rules and the gazetted invoice format with the Inland Revenue Department (ird.gov.lk) or your accountant.
