This Sri Lanka Salary Tax Calculator helps salaried employees accurately calculate their monthly income tax under the Advance Personal Income Tax (APIT) system. APIT is the tax deducted at source by employers on employment income, as required by the Inland Revenue Department (IRD) of Sri Lanka. The calculator is based on the official progressive tax slabs applicable for the Year of Assessment 2025/26.
Under the current tax structure, the first portion of monthly salary is tax-free, and higher income portions are taxed at increasing rates. This progressive method ensures that employees only pay higher tax rates on the part of their salary that exceeds each threshold, rather than on the entire income.
Sri Lanka salary tax is calculated on a monthly basis for employees under regular employment. Employers are legally required to deduct APIT every month and remit it to the IRD. The tax rates range from zero percent for lower income levels up to higher marginal rates for higher salary bands.
This calculator automatically applies each tax slab in sequence, calculates the taxable portion within each band, and provides a detailed breakdown of how the total tax amount is derived. The result includes the monthly tax, net salary after tax, annual tax liability, and the effective tax rate.
This calculator is intended for regular employment income only. It does not include other sources of income such as business income, rental income, or investment income. Tax reliefs, exemptions, and special cases may apply depending on individual circumstances and changes in tax regulations.
While every effort has been made to ensure accuracy, this calculator should be used as a guide only. For official tax filings and compliance, employees should refer to the Inland Revenue Department guidelines or consult a qualified tax professional.
Use this Sri Lanka Salary Tax Calculator to quickly understand how APIT affects your monthly income and to make informed financial decisions.
