Being your own boss is rewarding — but it also comes with responsibilities, especially when it comes to taxes. If you’re self-employed in Sri Lanka, filing your income tax return with the Inland Revenue Department (IRD) is a must.
This step-by-step guide explains how to file your self-employed tax return in Sri Lanka, what documents you need, and common mistakes to avoid.

- Earn income from commissions, professional fees, or rent

How to register:
