APIT Calculator — Sri Lanka 2025/26

APIT (Advance Personal Income Tax) is the income tax your employer deducts from your salary each month and remits to the Inland Revenue Department. Under the 2025/26 tax tables, the first Rs. 150,000 of your monthly gross is tax-free; above that, progressive slabs apply — and only the slice of income inside each band is taxed at that band's rate.

Example: on a Rs. 200,000 gross salary, APIT is Rs. 3,000/month — 6% of the Rs. 50,000 above the relief. The calculator also shows your EPF, stamp duty, net salary, and what any increment is really worth.
