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 are separate taxes governed by different legislation — the Withholding Tax Act and the Capital Gains Tax Act respectively. This guide addresses both.

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 is a capital gain. Under provisions that have historically been in force in Nigeria, gains from the disposal of shares listed on a recognised Nigerian stock exchange have been exempt from CGT under the Capital Gains Tax Act. This exemption has historically meant that most Nigerian retail investors selling NGX-listed shares have not paid CGT on their profits. However, this is a legislative exemption — it can be modified or removed. Verify the current position with a qualified Nigerian tax adviser before making significant disposal decisions.

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
• Capital gains: historically exempt for NGX-listed securities under the CGT Act — but subject to legislative change
• WHT is a final tax on dividend income for most resident individuals — no further income tax typically due
• CGT exemption is a legislative provision, not a permanent right — always verify the current position
• 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?

Under the CGT framework, capital losses may potentially be offset against capital gains in certain circumstances. However, if the historical exemption for NGX-listed securities applies, neither gains nor losses from listed shares would typically be within the CGT regime. Consult a qualified tax adviser if you are managing a significant loss position.

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).
