Sri Lanka VAT Invoice
IRD Gazette 2463/05 VAT tax-invoice format & e-Services VAT return preparation for Odoo
Issue Sri Lanka VAT tax invoices in the new format prescribed by Gazette (Extraordinary) No. 2463/05, mandatory from 1 April 2026, and prepare the periodic Inland Revenue Department e-Services VAT return schedules — output VAT, input VAT and the net VAT payable or refundable — with one-click IRD bulk-upload CSV export. After the SVAT repeal of 1 October 2025 the standard tax invoice is the sole VAT instrument and every mandatory particular is enforced.
Gazette 2463/05 tax invoice
A canonical document carrying every mandatory particular: the TAX INVOICE heading, supplier name/address and TIN / VAT registration number, a unique serial number and date, the registered purchaser’s TIN, per-line description, quantity, value excluding VAT, the VAT rate and amount, and the total payable including VAT.
S / Z / E tax bucketing
Standard-rated supplies at 18%, zero-rated supplies (exports) and exempt supplies are bucketed into the invoice VAT summary and into the return schedules, so the figures reconcile exactly with each tax invoice.
IRD e-Services VAT return
Build the Output Schedule (Schedule 01) and Input Schedule from the posted invoices in a period, review the computed output VAT, input VAT and net VAT, and download the IRD e-Services bulk-upload CSV files. Filing is performed by you on the IRD portal — the module prepares, it never transmits.
Real TIN validation
A real 9-digit IRD TIN structural validator with VAT activity-suffix handling and an advisory ISO 7064 MOD 11-10 check, enforced on the company and on every registered purchaser before a tax invoice is issued.
Self-verification QR
A compact QR carrying the supplier TIN, invoice number, date, total and VAT is rendered onto the printed tax invoice, letting purchasers verify the figures offline when reconciling input VAT.
Guided onboarding
A wizard validates the company TIN, derives the VAT registration number, and switches on the Sri Lanka VAT format in one step. An optional cron generates the prescribed payload for posted documents in bulk.
Built on the e-Invoice Core Engine
This connector reuses the shared e-Invoice Core Engine (canonical JSON builder, validation framework and e-Invoicing document model) and adds only the Sri Lanka format, validation profile and IRD return logic. No engine functionality is duplicated. Compatible with Odoo 18 and Odoo 19.
