Sri Lanka's National e-Invoicing System is being rolled out by the Inland Revenue Department (IRD) under the National Budget 2026. Following a pilot, selected export-oriented VAT-registered persons now transmit VAT invoice and schedule data directly from their ERP systems to the Revenue Administration Management Information System (RAMIS) in real time via a secure Web API, as set out in Notice SEC/PN/VAT/2026-03 . Garment export, tea export and tea manufacturing entities are already integrated. Full Web API integration is expected by the end of 2026.
B2C
planned
B2C supplies fall within the same real-time VAT reporting framework operated by the Inland Revenue Department through RAMIS, since transmitted schedules cover output tax including exempted supplies (Schedule 01) and zero-rated supplies (Schedule 07). No separate B2C deadline has been published.
B2G
planned
B2G supplies are administered under the same RAMIS-based reporting framework run by the IRD . The phased rollout in Notice SEC/PN/VAT/2026-03 is defined by taxpayer type (export-oriented enterprises first, then all VAT-registered persons) rather than by customer, so no distinct B2G timeline has been set.
Web API real-time transmission from taxpayer ERP to RAMIS
Supported Formats:
Not yet specified
Clearance Model:
Continuous Transaction Control through real-time reporting. VAT-registered persons transmit invoice and schedule data directly from their ERP systems to the Inland Revenue Department's RAMIS via a secure Web API as invoices are issued. There is no pre-clearance; records sent through the Web API cannot be amended or deleted, and corrections must be made by issuing a tax credit or debit note. Supplier-submitted Schedule 01 and Schedule 04 data is auto-populated into the purchaser's Schedule 02 and Schedule 04 for review and approval before input tax is claimed. The IRD plans to add pre-population of import data (Schedule 03) and export data (Schedule 06) using Sri Lanka Customs data.
