What You Need to Know About Taxes on Fixed Income Earnings

Let’s talk about taxes.

If you earn interest from fixed income investments in Nigeria, there’s a 10% tax on that interest. It’s called Withholding Tax (WHT), and it’s deducted automatically.

That’s the headline. Now let’s talk about what that actually means.

What Exactly Is Taxed?

Only your interest is taxed, your principal is not taxed. So if you invest ₦1 million, that ₦1 million comes back to you in full. No deductions. No surprises.

The tax only applies to the interest you earn on top of your capital.

How It Works 

Let’s use a simple example.

You invest NGN1,000,000 at 30% per annum for 12 months.

At maturity:

• Principal returned: NGN1,000,000
  
• Interest earned: NGN300,000
  
• Withholding Tax (10%): NGN30,000
  
• Interest you receive: NGN270,000

Your total payout is NGN1,270,000. (excluding platform fees)

That NGN30,000 is deducted and sent to FIRS automatically. You don’t need to calculate or remit anything yourself.

Can You Avoid This Tax?

No.

Withholding Tax on fixed income interest is mandatory and automatic. There are no legal shortcuts.

Anyone advertising “tax-free” fixed income returns is either wrong or being dishonest.

One Important Clarification

There is currently no capital gains tax on most debt instruments in Nigeria.

You’re taxed only on the interest earned, not on your principal and not on the return of your capital.

The Real Perspective

Paying ₦30,000 in tax on ₦300,000 earned is far better than paying ₦0 tax on ₦40,000 earned while inflation quietly erodes your money.

Tax doesn’t cancel out the advantage of fixed income.

It just means you should focus on net returns, not headline rates.
