Frequently Asked Questions: Sri Lanka Income Tax

Key details on tax brackets, standard deductions, and filing rules in Sri Lanka.

In Sri Lanka, income is taxed across progressive brackets. You only pay the higher tax rate on earnings within that specific bracket, not on your entire income. The first portion of your earnings is either tax-free or taxed at the lowest rate.
