Taxes on Fixed Income in Nigeria: What the SEC and FIRS Demand

The Federal Inland Revenue Service (FIRS) and SEC Nigeria set the rules. For treasury bills, interest is taxed at 10% withholding tax, but only if you hold them in a taxable account. For NGX stocks, you pay a 10% capital gains tax on profits from selling shares, and a 10% dividend withholding tax. In 2026, the CBN holds the policy rate at 22.75%, so yields are high. But do not forget: if you earn ₦100,000 from a ₦500,000 treasury bill, you owe ₦10,000 in tax. Always declare your income in your annual returns. The SEC also requires all investment platforms to be registered, so check before you deposit money.

CBN Rate Decisions and Naira Policy: How They Affect Your Returns

The Central Bank of Nigeria (CBN) controls the naira exchange rate and interest rates. In 2026, the CBN has kept rates high to fight inflation, which is good for fixed income investors. But the naira is still volatile. If you invest in naira assets, your real return depends on inflation. For example, a 20% yield on a ₦500,000 treasury bill gives you ₦100,000. If inflation is 15%, your real gain is only ₦35,000. The CBN also sets the exchange rate for foreign investors, so if you are a local, stick to naira products. Watch the CBN's monthly policy statements—they signal future rate moves.

Regulatory Compliance: What Every Investor Must Do in 2026

SEC Nigeria requires all investment platforms and mutual funds to be licensed. Before you invest, check the SEC's website for the product's registration number. You must also provide your Bank Verification Number (BVN) and Tax Identification Number (TIN) to any platform you use. For dividends, the company deducts withholding tax automatically, but you still need to report it on your tax return. If you invest through a fintech app like PiggyVest or Cowrywise, they are regulated by SEC, but you are responsible for declaring your earnings. Failure to declare can lead to penalties from FIRS. Keep records of all your transactions for at least 6 years.

Top 5 Fixed Income Products in Nigeria: Our 2026 Ranking

How to File Your Tax Returns on Fixed Income in Nigeria

You must file your annual tax return with FIRS by March 31st of the following year. For treasury bills, the bank sends you a certificate of tax deducted. For dividends, the company does the same. You add all these to your income and pay the difference. If you only earn from fixed income, you may not need to file if your total income is below the threshold, but it is safer to file anyway. Use the FIRS online portal, or hire a tax consultant. Penalties for late filing are ₦25,000 for small companies, but for individuals, it is 10% of the tax owed. Keep your TIN handy. In 2026, the FIRS is cracking down on undeclared crypto and fixed income, so do not try to hide anything.
