Do I Pay Tax on Stock Profits in Nigeria?

The Two Tax Questions Nigerian Stock Investors Ask Most

When Nigerian investors think about tax on their stock market activities, two questions come up most often: (1) Do I pay tax on dividend income from my Nigerian shares? (2) Do I pay tax on the profit I make when I sell shares for more than I paid? These questions concern different tax treatment. This guide addresses both, including the share-disposal rules introduced by the Nigeria Tax Act 2025 from 1 January 2026.

Tax on Dividend Income: Withholding Tax

Dividend income from NGX-listed shares is subject to withholding tax (WHT) deducted at source. This means the company (or its registrar) deducts WHT before the dividend reaches you. You receive the net dividend automatically — you do not need to remit a separate payment to FIRS for WHT already deducted. The WHT rate applicable to dividends is set by regulation. Verify the current rate with FIRS or a qualified tax adviser — do not rely on any specific rate quoted in articles, including this one, as rates may change.

Tax on Share Sale Profits: Capital Gains Tax

The profit you make when selling Nigerian shares for more than you paid may form part of a chargeable gain. The Nigeria Tax Act 2025 came into force on 1 January 2026 and replaced the previous capital gains tax framework. For individuals, chargeable gains are taxed at personal income tax rates (progressive bands), rather than the previous flat 10% rate. Gains on disposing of shares are exempt where total disposal proceeds are below ₦150 million and chargeable gains do not exceed ₦10 million in any 12 consecutive months. Where share-disposal proceeds are reinvested in shares of Nigerian companies, the reinvested amount is exempt. Confirm how the rules apply to you with a qualified Nigerian tax adviser.

Self-Assessment Obligations: What Investors Need to Declare

Nigerian taxpayers who earn investment income may have self-assessment obligations. If you earn salary or business income alongside investment returns, your annual tax return (filed via the FIRS Joint Tax Board system) may need to reflect your full income picture. Specific obligations depend on your employment status, income level, and whether your WHT credits are being properly accounted for. Consult a qualified Nigerian tax adviser to understand your annual filing obligations — particularly if you earn significant dividend income or make large share sales.

Key Differences: Dividends vs Capital Gains for Tax Purposes

• Dividends: taxed via WHT deducted at source before payment — you receive the net amount automatically
• Individual chargeable gains: taxed at personal income tax rates (progressive bands) under the rules in force from 1 January 2026
• WHT is a final tax on dividend income for most resident individuals — no further income tax typically due
• Share-disposal gains: exempt when both 2026 thresholds are met; reinvested proceeds also receive relief to the extent reinvested
• Different rates and rules apply to non-resident investors and corporate shareholders

Frequently Asked Questions

If WHT is deducted automatically, do I need to do anything for my taxes?

For most Nigerian resident individual investors who earn only salary income and dividend income with WHT already deducted, no additional payment to FIRS is typically required for the dividend income itself. However, if you also have self-employment income, rental income, or other income sources, you may still have an annual filing obligation. Consult a qualified tax adviser to confirm your position.

What if I bought shares at a loss and sold at a loss — is there any tax relief?

This guide does not cover how a capital loss on shares is treated. Confirm how a loss affects your position with a qualified Nigerian tax adviser.

Does the tax treatment differ for foreign shares?

Yes. Foreign dividends and capital gains from foreign shares are generally subject to different rules under Nigerian tax law, and you may also have tax obligations in the country where the shares are listed. International investors should consult a qualified tax adviser with cross-border expertise.

I reinvested my dividends — do I still owe WHT?

WHT is deducted at source regardless of what you do with the net dividend. If you reinvest the net dividend to buy more shares, the WHT was already paid when the dividend was distributed. The reinvestment itself is not a separate taxable event for WHT purposes.

Where do I go to file a tax return in Nigeria?

Federal income tax is administered by the Federal Inland Revenue Service (FIRS) at firs.gov.ng. For PAYE employees, tax is typically handled by your employer. Self-employed individuals and those with multiple income sources file self-assessment returns with FIRS. State-level taxes on some employment income are administered by the relevant State Internal Revenue Service (SIRS).
