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.


🧾 Who Is Considered Self-Employed in Sri Lanka?

According to the IRD, you are considered self-employed if you:

  • Run your own business or consultancy
  • Work as a freelancer (e.g., designer, IT, tutor, writer)
  • Earn income from commissions, professional fees, or rent
  • Do not earn a fixed salary (i.e., not under PAYE)

📌 Step 1: Register with the IRD

Before filing, you must have a Taxpayer Identification Number (TIN).

How to register:

  • Visit https://www.ird.gov.lk
  • Click “Register as a Taxpayer”
  • Submit your NIC copy, proof of address, and business registration (if applicable)

Once approved, you’ll get access to the e-Services portal to file your return.


🧮 Step 2: Calculate Your Income and Expenses

You need to declare:

  • Total income (freelance fees, rent, commissions, etc.)
  • Allowable expenses (rent, internet, stationery, travel, etc.)
  • Net Profit = Income – Expenses
