Let me break this down clearly — what you saw is normal banking behavior, not Easter gift 😄

You experienced two things:

Capitalized Interest (₦4,183 credited)

State Withholding Tax (₦400+ debited)

Let’s explain them one by one.

1. What is “Capitalized Interest”?

This is interest paid on money sitting in your account.

Banks sometimes pay interest on:

Savings accounts

Dormant accounts that still have balance

Certain current accounts (rare but possible)

So what likely happened:

Your Zenith account had money sitting there for a long time

Zenith calculated accumulated interest

Then they credited ₦4,183 as interest

This is not Easter gift 😄

It is interest you earned over time.

Since you said you haven’t used the account much, it’s possible:

The interest accumulated quietly

They paid it in bulk (capitalized interest)

2. What is State Withholding Tax?

State Withholding Tax = Tax deducted on interest earned

In Nigeria:

Interest earned from banks is taxable

Government collects 10% withholding tax on interest

So:

Zenith credited you ₦4,183 (interest)

Government collected about 10% tax (~₦418)

Bank deducted it as STATE WITHHOLDING TAX

That’s why you saw:

Credit: ₦4,183

Debit: ₦400+ (Tax)

This is normal and legal

Example (Simple Calculation)

Interest credited = ₦4,183

10% tax =

₦4,183 × 10% = ₦418.30

So bank deducts about ₦418

You keep the rest.

Will They Continue Debiting Your ₦2,500?

No. They will NOT randomly debit your ₦2,500

Important:

State Withholding Tax is only deducted when you earn interest

If no interest → No tax deduction

So:

They won’t just wake up tomorrow and debit ₦2,500

No need to panic 😄

How Often Will They Deduct It?

Only when:

Interest is paid (monthly / quarterly / yearly depending on bank)

Not daily.

Not randomly.

Why You Never Saw Interest Before (15 Years)

Possible reasons:

You were using current account (some don’t pay interest)

Balance too small to generate noticeable interest

Interest credited but too small to notice

Account type changed recently

One More Important Thing

Actually, this is good news:

You just received:

₦4,183 free interest

After tax, you still gained about ₦3,700+

So Zenith actually paid you money, not took your money.

My Honest Advice

No need to withdraw your ₦2,500 because of this.

But since you prefer:

Opay (less wahala)

Simple banking

You’re still fine to leave small balance in Zenith.
