Capital Gains Tax on Property in Nigeria
Property transactions are one of the most common sources of capital gains in Nigeria. When selling land or buildings, you must compute the gain as: Disposal Proceeds minus (Cost of Acquisition + Improvement Costs + Incidental Costs). The resulting gain is taxed at 10%.
For shares, the acquisition cost is the amount originally paid. For inherited property, the market value at the date of inheritance is used as the acquisition cost.
Frequently Asked Questions
What is Capital Gains Tax (CGT) in Nigeria?
CGT is a 10% tax on gains arising from the disposal of chargeable assets in Nigeria. It is governed by the Capital Gains Tax Act. Chargeable assets include land, buildings, shares, bonds, goodwill, and other capital assets. The gain is the selling price minus the original purchase price and improvement costs.
Are all assets subject to CGT in Nigeria?
Not all assets attract CGT. Exempt assets include: compensation for personal injury, gains on government securities (treasury bills, bonds), and gains on the disposal of a principal private residence (your main home) under certain conditions. Gains from business stock and trading profits are subject to income tax rather than CGT.
How are improvement costs treated for CGT?
Costs of permanent improvements to an asset — such as extensions, renovations that increase value, and major upgrades — are deductible from the capital gain. Routine maintenance and repairs are generally not deductible as they are revenue expenditure.
When is CGT payable in Nigeria?
CGT is due when a chargeable asset is disposed of — sold, gifted, exchanged, or otherwise transferred. The tax must be self-assessed and paid to FIRS within the relevant assessment period. For individuals, State IRS may have jurisdiction depending on the nature of the asset.
What is the CGT rate in Nigeria?
The CGT rate in Nigeria is a flat 10% on the net capital gain. Unlike income tax, there are no progressive bands — the same 10% rate applies regardless of the size of the gain.
