What Is Income Tax and Who Has to Pay It in Sri Lanka

That's the short version. Here's what each part of it means.

What income tax actually is

You earn money. The government takes a share. That share is income tax, collected by the Inland Revenue Department (IRD).

It isn't a fee for a service. It isn't linked to anything you receive in return. It's a percentage of what you earned, calculated once a year.

It's not the only tax you pay

Most people in Sri Lanka pay tax every day without noticing. It helps to know which tax is which.

When you buy something and see VAT on the bill, that's a separate tax with separate rules. Paying VAT on your shopping has nothing to do with whether you owe income tax.

There are others too, like stamp duty on certain documents and import duties on goods coming into the country. This guide is only about income tax.

The tax year is not the calendar year

This catches almost everyone out.

Sri Lanka's tax year runs 1 April to 31 March. The law calls it a "year of assessment".

So the year of assessment 2025/2026 covers 1 April 2025 to 31 March 2026. If someone mentions "the 2025/2026 return", that's the money you earned across those twelve months.

Your return for that year is due by 30 November 2026.

What counts as income

The law splits everything you earn into four buckets.

• Employment income. Salary, wages, overtime, bonuses, commissions, allowances, gratuity. Anything an employer pays you.
• Business income. Money from running a business or working for yourself. Freelance fees, consulting fees, shop profits.
• Investment income. Money your money makes. Bank interest, dividends, rent from a property you own, royalties.
• Other income. Anything that doesn't fit the three above.

Here's the part people miss: your tax is worked out on all four added together, not on each one separately.

What doesn't count

Not everything that lands in your bank account is taxable income.

• Selling your car at a profit is not income. If you sell a personal vehicle for more than you paid, that gain isn't taxed. This was clarified in 2026 and applies backwards from April 2024. It doesn't apply if the vehicle was trading stock or a business asset you claimed capital allowances on.
• Some income is exempt outright. The law has a list of amounts that are free of tax entirely. It's long and specific, so we cover it properly in its own guide rather than half-explaining it here.
• A genuine one-off windfall isn't "other income". The law specifically leaves out profits that are casual and non-recurring.

Who has to pay

It comes down to whether you're a tax resident of Sri Lanka.

If you're a resident, you pay Sri Lankan tax on income from anywhere in the world. Money earned abroad counts, even if it never reaches a Sri Lankan bank account.

If you're not a resident, you only pay on income with a Sri Lankan source.

You're a resident if you live in Sri Lanka, or if you're physically here for 183 days or more across any twelve month period that starts or ends during the tax year. There are extra rules for government officials whose spouse is posted abroad, and for people employed on Sri Lankan ships.

For most people reading this: if you live here, you're a resident.

One thing that works differently

If you sell an asset like land or shares at a profit, that's a capital gain. It's taxed at a flat 15%, separately from everything above, and it has its own return with its own deadline.

So how much do you actually pay?

Not on all of it. The first Rs. 1,800,000 you earn in a year is free of tax, and the rate on what's left climbs in steps rather than hitting the whole amount.

That's the next guide in this chapter.
