Free income tax calculator for Sri Lanka
Enter one number you already know, your monthly salary before deductions, and see what you actually pay in tax each month and each year. The rates are the ones in force from 1 April 2025.
How this tax calculator works
Step 01
Put in your monthly salary before deductions, the gross figure your employer quotes, not what lands in your account
Step 02
The first Rs. 150,000 a month, Rs. 1,800,000 a year, is set aside as personal relief and is not taxed at all
Step 03
Everything above that is taxed slab by slab, from 6% up to 36%, and only the slice sitting inside a slab pays that slab's rate
Step 04
Get back your monthly and annual tax as rupee figures, with the slab breakdown shown, so the number stops being a mystery

How much salary is tax free in Sri Lanka?
The first Rs. 150,000 a month, or Rs. 1,800,000 a year, is personal relief and is not taxed. If your monthly salary is at or below that figure, no income tax is deducted from it. The relief was raised from Rs. 1,200,000 a year with effect from 1 April 2025.
Is PAYE the same as APIT?
Yes, in practice. PAYE was renamed Advance Personal Income Tax, and it works the same way: your employer deducts the tax from your salary each month and pays it to the Inland Revenue Department on your behalf. Most people still search for it as PAYE, so both names point to the same deduction.
Why is my tax smaller than my tax rate?
Because the rates are progressive. Only the portion of your salary that falls inside a slab is taxed at that slab's rate, so reaching the 18% band does not mean 18% of everything you earn. Your effective rate, the tax as a share of your full salary, is always lower than the top band you touch.
