Comprehensive breakdown of Inland Revenue Department (IRD) income tax slabs, monthly PAYE/APIT deductions, and net salary calculations.
📑 What is Advance Personal Income Tax (APIT)?
In Sri Lanka, individual employment income is taxed at source under the Advance Personal Income Tax (APIT) framework administered by the Inland Revenue Department (IRD). Under the Inland Revenue Act, employers are legally mandated to deduct APIT directly from employees' monthly payroll and remit it to the IRD on or before the 15th of the subsequent month.

Frequently Asked Questions (FAQ) - Sri Lanka APIT Tax
❓ Can I claim tax deductions for EPF or ETF contributions?
Under the current Inland Revenue Act amendments, mandatory employee 8% EPF deductions are not exempt from gross employment receipts for APIT purposes. However, employer contributions (12% EPF and 3% ETF) are paid directly by the employer and are not treated as employee taxable cash income.
❓ What if I work multiple jobs or have freelance income?
Your primary employer applies the tax-free relief threshold (Rs. 100,000/mo). If you earn secondary income or freelance remuneration, secondary employers are required to deduct APIT at a flat rate of 14% or according to cumulative IRD tax direction forms.
❓ How do I verify my annual tax payments with the IRD?
At the end of each Assessment Year (ending March 31), employers are required to issue a Certificate of Income Tax Deductions (T-10 form) to every employee. You can file your annual tax return via the IRD RAMIS online portal using your TIN login.
