Who should NOT buy LankanTax

  • Salary-only employees with APIT correctly deducted. The law (s.94 of the Inland Revenue Act) generally doesn’t require you to file a return at all — you may not need any software. Check your situation in the income tax guide first.
  • Anyone who wants a human to do it for them. Simplebooks’ reviewed service or a licensed tax practitioner is the better fit — LankanTax is software only.
  • Rs 0 budget with a simple return. Use the IRD portal with our free step-by-step guide and the free calculator to sanity-check the numbers.
