Capital Gains Tax on Property Sales in Sri Lanka: What the 15% Rate Means for You

If you're planning to sell property in Sri Lanka, a change that took effect this year directly affects how much of your profit you keep. Under the Inland Revenue (Amendment) Act No. 11 of 2026, certified on June 3, 2026, the Capital Gains Tax rate for individuals and partnerships rose from 10% to 15%. If your sale closes today, this is the rate you're working with.

This guide walks through what changed, who it affects, how the gain is actually calculated, and which exemptions still apply.

What Changed Under the 2026 Amendment

Three changes matter most for property sellers.

The CGT rate increased to 15%. This applies to gains made by resident individuals and partnerships on the disposal of investment assets, which includes land, buildings, and most capital property. The new rate took effect on June 3, 2026, the date the Act was certified. If your sale closed before that date, the previous 10% rate still applies, which matters if you're filing late for an earlier disposal.

A TIN certificate is now mandatory for property registration. Since April 1, 2026, you must present a Taxpayer Identification Number certificate to the Registrar General's Department to register land or title, in addition to needing one for building plan approval and several other transactions. If you haven't registered for a TIN yet, do this before you list your property, since it can otherwise delay your registration date at settlement.

Gifts to the Government or a public university are now exempt. If you transfer property as a gift to the Government of Sri Lanka or a qualifying university, this is treated as a no gain, no loss event, so no CGT applies.

What Counts as an Investment Asset

The definition is broad. It includes land, buildings, unlisted shares, and most other capital assets held for investment purposes. Two notable exclusions.

• Your principal residence, if it qualifies for the exemption described below
• Shares listed on the Colombo Stock Exchange, which are fully exempt from CGT Capital gains are taxed separately from your salary or business income. The progressive income tax slabs and your personal relief threshold don't apply to a property sale, so you can't offset a capital gain against unused personal relief.

How the Gain Is Calculated

Your taxable gain is the sale price minus your cost base, minus any allowable incidental costs (legal fees, valuation fees, and similar transaction costs directly tied to the purchase or sale). The remaining figure is taxed at 15%.

If you bought before 2018, the calculation works slightly differently. For any asset you already held on September 30, 2017, the cost base is deemed to be the property's market value on that date, not what you originally paid. Improvements and incidental costs incurred after September 30, 2017 are added on top of that base. In practice, this means you're only taxed on the appreciation that occurred after September 30, 2017, not the full lifetime gain.

Exemptions Worth Knowing

Principal residence exemption. If the property you're selling is your main home, the gain can be fully exempt from CGT. To qualify, you need to have owned the property for the three years immediately before the sale and lived in it for at least two of those three years. If both conditions are met, you owe no capital gains tax on that sale at all.

Small gains exemption. A gain of Rs. 50,000 or less is exempt, but only if your total capital gains for the entire year of assessment don't exceed Rs. 600,000. In practice, most land and building sales are well above both thresholds, so this exemption rarely applies to a typical property transaction, but it's worth checking if you're selling a smaller asset alongside other capital disposals in the same year.

Gifts to Government or universities. As noted above, transfers by gift or donation to the Government of Sri Lanka or a qualifying public university are treated as no gain, no loss, so no tax is triggered.

When and How to Pay

You need to file your Capital Gains Tax Return and pay the tax within 30 days of the end of the calendar month in which the sale took place. This is a firm deadline set under the Inland Revenue Act, so it's worth planning your settlement timeline with this window in mind rather than treating it as part of your annual tax return cycle.

What This Means for Your Sale Timeline

If you're weighing when to sell, the CGT rate itself shouldn't be the deciding factor since it applies uniformly regardless of timing. What does matter is making sure you have your TIN certificate in place before you begin the registration process, and confirming early whether the principal residence exemption applies to your situation, since that can be the difference between a 15% tax bill and no CGT at all.
