Is foreign exchange forex income taxable in Sri Lanka

If you are a resident in Sri Lanka, your global income (including forex trading, freelance payments, online earnings, or investments abroad) is subject to income tax under the Inland Revenue Act.

If you are a non-resident, only income earned or derived from Sri Lanka is taxable, so foreign forex earnings outside Sri Lanka are generally not taxed.

The applicable tax rate depends on your total annual income and is calculated according to the individual income tax slabs.

In summary: If you are a tax resident in Sri Lanka, forex income is taxable.
