Sri Lanka’s tax landscape is evolving, and businesses need to stay ahead. With the publication of Gazette No. 2463/05 on 17 November 2025, the government has introduced a new mandatory VAT Tax Invoice format. This format will become effective on 01 January 2026, and every VAT-registered business must update its invoicing system to comply with these requirements.
This change is not just about layout; it is aimed at improving tax compliance, transparency, and uniformity in VAT documentation. For businesses, understanding these changes is essential to avoid disruptions, ensure smooth operations, and maintain compliance with the Inland Revenue Department (IRD).
Why the New VAT Invoice Format Was Introduced
Tax invoices are critical in the VAT system. They allow businesses to charge output VAT and claim input VAT. However, inconsistent invoice formats have caused errors, delays, and difficulties during audits.

By standardizing the invoicing system, the government ensures that all essential information is clearly captured on every VAT invoice, minimizing mistakes and potential disputes.
New VAT Registration Threshold Effective From 01 April 2026
A key update that affects many businesses is the new VAT registration threshold. Currently, the mandatory VAT registration threshold is LKR 60 million per annum.
However, effective 01 April 2026, this threshold will be reduced, meaning more businesses will fall under the VAT system.
New VAT Threshold (From 01 April 2026)
- LKR 36 Million per annum (12-month period)
This update means:
-
Many small and medium businesses that previously did not meet the LKR 60 million requirement may now qualify for VAT registration.
-
If your turnover exceeds the new threshold, VAT registration becomes compulsory.
-
Once registered, you must follow all VAT regulations, including using the new VAT Tax Invoice format effective from 01 January 2026.
Who Must Comply With the New Format?
The new VAT invoice format is mandatory for all VAT-registered businesses in Sri Lanka, including:
-
Retailers and wholesalers
-
Service providers
-
Professionals offering taxable services
-
Corporate and small businesses
Failure to comply may result in:
-
Disallowed input tax claims
-
Penalties for non-compliance
-
Delays in VAT refunds
-
Challenges during audits
Even businesses with only occasional VAT transactions must adopt the new format to avoid complications.
