Income tax for professionals in Sri Lanka — Y/A 2025/2026

A worked example for professionals

Illustrative figures for a typical income mix for professionals — employment salary, bank interest — using the default amounts below. Your own numbers will differ; use the wizard above for your actual figures.

This page covers whatever mix of income sources your year actually produced, so the single most useful thing you can do before filing is confirm which schedules apply to you specifically rather than assuming a return only needs one — most first-time filers with more than one income source are surprised to find they need two or three schedules, not because the tax is complicated but because each source is assessed under a different part of the return. If none of the profession-specific pages match your situation closely, the wizard above still derives the right combination from your actual selections; the underlying tax treatment (APIT credits, AIT credits, the rental allowance, the foreign remittance ceiling) is identical regardless of what your job title happens to be. Keep source documents — payslips, bank remittance advices, WHT certificates, rent agreements — organised by income type as they arrive through the year rather than gathered retroactively in March; reconstructing a full year's income sources from memory is the most common cause of both late filing and understated reliefs. If your situation changes significantly mid-year — a new income source starts, an old one stops — your quarterly instalment estimate should be revised rather than left on the original figure, since a large gap between estimated and actual liability carries its own penalty exposure independent of the return itself.

Common questions

Who has to file an income tax return in Sri Lanka?

Anyone with assessable income above the Rs. 1,800,000 personal relief, anyone with more than one income source, and anyone who wants to reclaim APIT or AIT withheld in excess of their liability.

When is the Y/A 2025/2026 return due?

The return is due on or before 30 November 2026, covering 1 April 2025 to 31 March 2026. Note that the balance payment falls earlier, on 30 September 2026 — you pay before you file. Late filing carries a penalty of Rs. 50,000 plus Rs. 10,000 a month.

What are the slab rates for Y/A 2025/2026?

After the Rs. 1,800,000 personal relief: 6% on the first Rs. 1,000,000 of taxable income, then 18%, 24% and 30% on successive Rs. 500,000 bands, and 36% on the balance.
