APIT FAQs
What is APIT?
APIT (Advance Personal Income Tax) is the tax your employer withholds from your salary each month and remits to the IRD on your behalf. It applies progressive rates from 6% to 36%.
What is the tax-free threshold?
From 1 April 2025 (Y/A 2025/2026, unchanged for 2026/2027), the personal relief is LKR 1,800,000 a year (LKR 150,000 per month). Income up to that amount is free of income tax.
Are there any deductions I can claim?
Qualifying payments like employee EPF contributions, approved donations, and certain insurance premiums may be deductible. This calculator shows the basic APIT before such deductions.
