Tax On Fixed Income Investments In Nigeria (2026 Guide)

Estimated Reading Time: 8 minutes

If you’re investing in Treasury bills, fixed deposits, corporate bonds, or commercial papers, you won’t receive every naira you earn. Most fixed income investments in Nigeria are subject to a 10% withholding tax, deducted automatically before the money reaches your account. The major exception is FGN Bonds, which are currently tax‑exempt.

That distinction matters. On a ₦5,000,000 investment earning 15% annually, the tax‑exempt investor keeps ₦750,000. The taxable investor keeps ₦675,000. Same return, same principal, but ₦75,000 disappears each year—quietly, automatically, and often without the investor realising it until the money arrives.

This guide breaks down exactly how tax on fixed income investments in Nigeria works—instrument by instrument, with clear examples and no guesswork. If you’re completely new to fixed income, the complete beginner’s guide to fixed income investments gives you the full landscape.

Quick Tax Table

Investment	Tax
FGN Bonds	Tax Free
Savings Bonds	Tax Free
Sukuk	Tax Free
Treasury Bills	10% WHT
Fixed Deposits	10% WHT
Corporate Bonds	10% WHT
Commercial Papers	10% WHT

WHT = Withholding Tax. Tax treatment is based on current Nigerian legislation as of 2026. Always verify with a licensed tax professional, as regulations can change.

How Withholding Tax Works on Fixed Income

Withholding tax is deducted at source—meaning you don’t file anything, and you don’t send money to the government yourself. The bank, broker, or issuing institution takes the tax out before the money reaches your account.

If you earn ₦100,000 in interest on a fixed deposit, the bank deducts ₦10,000 and credits you with ₦90,000. The ₦10,000 goes directly to the Federal Inland Revenue Service (FIRS). You don’t need to report it again on your personal tax return unless you have other income sources that require filing.

This system makes compliance simple, but it also means you need to know the tax status of any instrument before you invest—because the deduction happens whether you were aware of it or not.

Tax Treatment by Investment Type

FGN Bonds — 0% (Fully Exempt)

This is one of the strongest reasons investors choose FGN bonds. Under current Nigerian law, interest earned on Federal Government of Nigeria bonds—including both standard FGN bonds and FGN savings bonds—is completely exempt from withholding tax and income tax.

Every kobo of interest paid to you stays with you. Over a 10‑ or 20‑year bond, the tax savings alone can amount to millions of naira. For a detailed look at how FGN bonds work, see the FGN bonds explained guide.

Sukuk Bonds — 0% (Fully Exempt)

Sukuk bonds, issued by the Federal Government for infrastructure projects, are also tax‑exempt. Returns are paid as profit‑sharing rather than interest, and they enjoy the same 0% tax treatment as conventional FGN bonds. For more, see the guide to Sukuk bonds in Nigeria .

Treasury Bills — 10% Taxable

Treasury bill returns are subject to a 10% withholding tax. If you buy a 364‑day T‑bill and earn ₦200,000 in profit, the bank or broker deducts ₦20,000 before the money reaches you.

This tax applies whether you buy through a bank, an app, or a stockbroker. There is no exemption for small amounts or first‑time investors—if you earn a return, 10% is deducted. For more on how T‑bill returns are calculated, see the guide to Treasury bills in Nigeria .

Fixed Deposits — 10% Taxable

Fixed deposit interest is taxed the same way as Treasury bills—10% deducted at source. The difference is that fixed deposit rates are usually lower to begin with, so the tax bite feels proportionally larger.

If you earn ₦60,000 in interest on a ₦500,000 fixed deposit, the bank deducts ₦6,000 and you receive ₦54,000. For a full comparison, see the fixed deposit vs Treasury bills guide.

Corporate Bonds — 10% Taxable

Corporate bonds are issued by companies rather than the government. The interest they pay is subject to 10% withholding tax, just like Treasury bills. Unlike FGN bonds, there is no tax exemption—even if the company is a well‑known blue‑chip. For more on corporate bonds, see the corporate bonds guide .

Commercial Papers — 10% Taxable

Commercial papers are short‑term corporate debt. Returns are taxed at 10%, same as corporate bonds and Treasury bills. The higher yields on CPs partly compensate for this, but the tax still reduces your net return. For a beginner‑friendly breakdown, see the commercial papers guide .

Which Fixed Income Investment Gives the Best After‑Tax Return?

People don’t just want tax rules—they want to know which investment leaves them with the most money. Here’s what happens when you invest ₦5,000,000 at a 15% annual return across different instruments:

Investment	Gross Return	Tax	Net Return
FGN Bond	₦750,000	₦0	₦750,000
Treasury Bill	₦750,000	₦75,000	₦675,000
Fixed Deposit	₦750,000	₦75,000	₦675,000
Commercial Paper	₦750,000	₦75,000	₦675,000

The tax‑exempt investor keeps ₦75,000 more per year than everyone else—on the same principal and the same headline return. Over 10 years, that’s ₦750,000 in tax savings from a single investment. This is why tax shouldn’t be an afterthought; it should be part of your decision from day one.

Common Tax Mistakes Investors Make

Numbers	Mistake	What Actually Happens
1	Assuming Treasury Bills are tax‑free	T‑bills are taxable at 10%. FGN bonds are the tax‑exempt ones. Don’t confuse the two.
2	Thinking the bank forgot to pay interest	The bank didn’t forget—they deducted withholding tax before crediting you. Check your statement for the tax line.
3	Confusing FGN bonds with corporate bonds	FGN bonds are tax‑exempt. Corporate bonds are taxable. The name matters.
4	Ignoring after‑tax returns when comparing investments	A 15% taxable return nets you 13.5%. A 13% tax‑exempt return gives you the full 13%. Sometimes the lower headline rate wins.
5	Not factoring tax into long‑term projections	₦75,000 lost to tax annually becomes ₦750,000 over a decade. Over 20 years, it’s ₦1.5 million. Tax compounds against you.
