Withholding Tax on Nigerian Dividends: What Foreign Investors Should Know

If you’re a foreign or diaspora investor considering NGX shares, including a future Dangote IPO, understanding Nigerian dividend withholding tax (WHT) helps you estimate your actual, after-tax return. Here’s the general framework, based on Nigerian tax rules as they currently stand.

Nigeria applies a standard withholding tax on dividends of 10%, deducted at source before the dividend reaches the shareholder, meaning the company (or its registrar) withholds the tax and pays you the net amount, remitting the withheld portion to Nigeria’s tax authority. This applies broadly, whether the shareholder is a Nigerian resident individual, a Nigerian company, or a foreign investor, under current rules including the Nigeria Tax Act framework effective from 2026.

For investors resident in countries that have an effective double taxation agreement (DTA) with Nigeria, a reduced withholding tax rate of 7.5% can apply instead of the standard 10%, provided the investor can demonstrate treaty residency (typically through a tax residency certificate) and meets the specific conditions of the relevant treaty; conditions can include minimum shareholding thresholds in some treaties. Nigeria has DTAs with a number of countries, including the United Kingdom, and the specific list and terms can change, so this shouldn’t be assumed without checking current status for your specific country.

It’s also worth understanding that withholding tax is typically a final tax on passive income like dividends for non-resident individual investors in many cases, meaning you generally wouldn’t owe additional Nigerian tax on that dividend income beyond what’s withheld, but you may still have reporting or tax obligations in your own country of residence, depending on your local tax rules and any relief available for foreign tax already paid.

Because tax rules are specific to your personal residency and can change, this is genuinely worth confirming with a tax adviser familiar with both Nigerian tax law and your home country’s rules before assuming a specific effective rate applies to you.
