Under the Nigeria Tax Act 2025, chargeable gains move into the income-tax framework: companies at 30%, individuals at the progressive 0%–25% PIT bands, with the new ₦150M / ₦10M share-disposal exemption and reinvestment relief.
Capital gains tax due
Effective rate on gain: 16.25%
The flat 10% Capital Gains Tax is gone. From 1 January 2026, gains are chargeable gains taxed within income: a company pays 30% (the CIT rate), while an individual adds the gain to other chargeable income and pays the progressive PIT rates (0%–25%). For individuals, the calculator taxes the gain at your marginal band by stacking it on the other income you enter.
Two reliefs matter for shares: the disposal is exempt if proceeds are below ₦150,000,000 AND the gain is ≤ ₦10,000,000 in 12 months; and reinvestment relief exempts gains to the extent proceeds are reinvested in Nigerian-company shares in the same year. Individuals can set their band with the PAYE calculator.

The standalone Capital Gains Tax Act is repealed. Companies now tax chargeable gains as part of total profits at the 30% CIT rate; individuals tax chargeable gains at the progressive personal income tax bands (0%–25%). The old flat 10% rate is gone.
Disposal of shares is exempt where aggregate proceeds are below ₦150,000,000 in any 12 months AND the chargeable gain does not exceed ₦10,000,000 in that period. Both conditions must hold — a large gain on modest proceeds no longer qualifies.
Yes. Gains on shares of Nigerian companies are exempt to the extent the disposal proceeds are reinvested in shares of Nigerian companies within the same year of assessment. Partial reinvestment gives proportionate relief.
No. A qualifying small company is exempt from tax on chargeable gains.
