Why IRD Invoice Compliance Matters — And How AccSoft ERP Keeps You Ready

Sri Lankan businesses are required to comply with the standardised invoice format requirements introduced by the Inland Revenue Department (IRD), particularly regarding VAT invoices and tax documentation. Failure to comply may result in unnecessary tax complications, audit issues, and difficulties for customers claiming Input VAT.

AccSoft ERP is fully compatible with IRD invoice template requirements, helping businesses generate compliant invoices automatically without manual intervention.

What Does the IRD Require in a Tax Invoice?

According to the Inland Revenue Department (IRD), a tax invoice should contain important information such as:

  • The words “Tax Invoice” clearly displayed
  • Supplier’s name, address, and Taxpayer Identification Number (TIN)
  • Customer’s name, address, and TIN (where applicable)
  • Unique invoice serial number
  • Invoice date and date of supply
  • Description of goods or services supplied
  • Quantity and unit information
  • Taxable value
  • VAT amount
  • Total invoice value

Recent IRD guidance has further standardised invoice layouts and mandatory data fields to improve transparency and tax administration.

As shown above, businesses must include supplier details, purchaser information, TIN numbers, invoice references, VAT calculations, and total invoice values in the prescribed format. Managing these requirements manually can be time-consuming and prone to errors. AccSoft ERP automates the entire process while ensuring compliance with IRD requirements.

It refers to the location from which the goods or services were supplied. This information should appear on the invoice as required by IRD guidelines.

What values should be shown on the invoice?

The invoice should clearly show the Value before VAT, the VAT Amount, the Total Amount Including VAT, and the Total Amount Written in Words. This helps both suppliers and customers clearly understand the transaction.
