Whether you are an individual income tax payer or a company, this article will provide a comprehensive guide to Income Tax in Sri Lanka in 2020.

What is an Income Tax? 

Income Tax, introduced in 1932, is governed by the Inland Revenue Department with the authority to charge, levy and collect income tax on individuals, partnerships, sole-proprietorships or companies.

Governments use income tax as a way to collect earnings from your business or personal profits, which is used to cover various government costs, including infrastructure development and public services such as health and education.

Income Tax Rate for Individuals

Depending on how much you earn, the total income tax you pay varies. This is categorized under different tiers, known as ‘Tax Slabs’. If your monthly earnings surpass 250,000 LKR, or 3,000,000 LKR annually, you are liable to pay income tax. 

The following sources of income will be considered as part of your taxable income:

  • Employment Income
  • Business Income
  • Investment Income
  • Other Income
