LankanTax exists because working out your income tax in Sri Lanka is harder than it should be. Official sources are accurate but hard to navigate; most third-party articles are out of date the moment rates change. We build free calculators and plain-language guides that are updated the day the rules change — and we show our sources.

Who is behind LankanTax

LankanTax content is reviewed by our co-founder Sampath Munasinghe, a taxation professional and accountant in Sri Lanka. Sampath is the former Director of Tax at B. R. De Silva & Co., Chartered Accountants, a Fellow Member (FTII) of the Sri Lanka Institute of Taxation and an elected member of its Executive Council, and a Chartered Tax Advisor (CTA) through the Institute of Chartered Accountants of Sri Lanka. His day-to-day work covers personal and corporate tax computations, statutory compliance, and representation before the Inland Revenue Department — the same rules our calculators implement.

The guides and calculators are written and maintained by Anudi Imesha, LankanTax’s Customer Success Consultant. Anudi drafts every page from the Inland Revenue Act, IRD notices and the published tax tables, keeps the worked examples current, and answers reader questions. Every tax page shows who wrote it and who reviewed it, with the date it was last updated; pages whose numbers are still awaiting a written ruling say so instead of carrying a reviewer’s name.

What we will always do

  • Cite the Inland Revenue Act and IRD notices for every rule we state.
  • Date-stamp every page, and update calculators and guides the day rates change.
  • Fix errors publicly and fast — accuracy reports are the highest-priority issue on this site.

What we don’t do

We don’t give individual tax advice. The calculators produce estimates for common situations; for complex affairs, engage a licensed tax practitioner. See how our calculators work for exactly which rules we implement and how we verify them.
