Nigeria Capital Gains Tax
Capital Gains Tax (CGT) in Nigeria is a tax levied on the profit (or gain) made from selling or disposing of a chargeable asset that has increased in value since you acquired it. The primary law governing CGT is the Capital Gains Tax Act, Cap C1 LFN 2004, which has been amended by various Finance Acts. Currently, capital gains are generally taxed at a flat rate and are not integrated into personal or corporate income tax.
How is Capital Gains Tax Calculated?
The calculation follows a straightforward process:
- Determine the Chargeable Gain: This is the taxable profit. It is calculated as the Sale Price minus the original Acquisition Cost and any eligible Improvement Costs (capital expenditures that enhance the asset's value).
- Apply Exemptions: Nigerian law provides specific exemptions that can reduce or eliminate the tax:
- Principal Private Residence: Gains from the sale of your main residence are exempt from CGT. The exemption typically applies if the property was your main residence throughout the entire period of ownership. Partial ownership periods may lead to a partial exemption.
- Small Share Sales: Gains of NGN 100,000 or less from the sale of shares are exempt if you have held those shares for at least 5 complete years.
- Apply the Tax Rate: The remaining taxable gain is multiplied by the applicable Capital Gains Tax rate. The standard rate under the Act is 10% for both individuals and companies. This is the default rate used in this calculator.
Example Calculation
Let's say Mr. Adebayo sells a rental property (not his main home) for NGN 50,000,000. He bought it for NGN 30,000,000 and spent NGN 5,000,000 on major renovations.
- Chargeable Gain: 50,000,000 - 30,000,000 - 5,000,000 = NGN 15,000,000
- No exemptions apply (it's not his principal private residence).
- Taxable Gain: NGN 15,000,000
- Tax Rate: 10%
- Capital Gains Tax Due: 15,000,000 * 10% = NGN 1,500,000
Common Scenarios
- Selling Your Home: If it was your main residence for the entire time you owned it, the entire gain is tax-free. If you lived there for only part of the time, a proportional exemption may apply.
- Selling Shares: Small, long-term gains (≤ NGN 100,000 held for 5+ years) are exempt. Larger gains are taxed at the standard CGT rate (default 10%).
- Selling a Business Asset: Both individuals and companies pay CGT on the gain at the standard rate, unless a specific provision applies.
Important Considerations and Next Steps
Tax reforms in Nigeria are ongoing. While this calculator uses the established 10% flat rate, always verify the current rate with the Federal Inland Revenue Service (FIRS), especially for transactions in 2026 and beyond. The input for 'Capital Gains Tax Rate' allows you to adjust if you are using a confirmed different rate.
After estimating your tax liability, you must formalize the transaction with the appropriate legal document. For the sale of real property, use a Contract of Sale of Real Property. For the sale of company shares, a Share Sale and Purchase Agreement is required. For the sale of business assets, an Asset Sale and Purchase Agreement is essential. These documents record the sale price and acquisition costs, which form the basis of your tax calculation.
