Important Update from Inland Revenue Department

The Commissioner General of Inland Revenue has issued a new specification for Tax Invoices under the Value Added Tax Act, No. 14 of 2002. This change, published in Gazette Extraordinary No. 2463/05 dated November 17, 2025, becomes mandatory from January 1, 2026( Postponed to 1 April 2026). All VAT-registered persons must adopt the new invoice format by the effective date.

Failure to comply may result in penalties or rejection of input VAT claims. It is crucial to update your invoicing systems well in advance.
