Tax filing is simply telling the government how much you earned last year.

That’s all.

The Authority in Anambra

Your tax is handled by:

👉 Anambra State Internal Revenue Service

Important Terms (Let’s Remove Fear First)

1. ASIN (Very Important)

ASIN = Anambra State Identification Number

👉 This is your tax ID in Anambra

Like:

• school registration number
• hospital card

Without it:

✓ you cannot file properly

2. Annual Returns

This simply means:

👉 report of your income for the year (e.g. 2025)

Let Me Explain With a Simple Story

Mama Ngozi sells tomatoes in Onitsha.

At the end of 2025:

She goes to the tax office and says:

👉 “This is how much I made last year.”

That is:

✓ tax filing
✓ annual return

Oya… Relax Let Me Explain (STEP-BY-STEP)

STEP 1: Get Your ASIN

How?

Go to:

• Anambra tax office
OR
• their official portal (if available)

What You’ll Provide

• full name
• phone number
• address
• ID (NIN or others)

Result

👉 You get your ASIN number

STEP 2: Know Your Income

Calculate what you earned in 2025:

• salary
• business income
• side hustle

Example

Mama Ngozi:

• total sales profit = ₦800,000

STEP 3: Deduct Allowances

Government allows small reliefs.

This reduces your taxable income.

(If you are a salary earner, many are already deducted)

STEP 4: Fill Your Annual Return

You can do this:

• online (if portal is working)
OR
• physically at tax office

What You Fill

• your ASIN
• your total income
• your deductions

STEP 5: Calculate Tax

Nigeria uses graduated tax system

Meaning:

• small income → small tax
• higher income → higher tax

👉 If you are employed:

✓ tax may already be deducted (PAYE)

STEP 6: Submit Before Deadline

Important

Deadline is usually:

👉 March 31 every year

(for previous year income)

STEP 7: Pay (If Necessary)

If tax is not fully paid:

✓ you pay balance

If already deducted:

✓ just file and confirm

Let Me Be Honest With You

Most mistakes happen because people:

• ignore tax completely
• wait till deadline
• don’t register early

Common Mistakes to Avoid

• not getting ASIN
• guessing income wrongly
• missing deadline
• ignoring filing because “no one told me”

What If You Have No Income?

Very important.

If you didn’t earn:

✓ you may still file NIL return

Meaning:

👉 “I earned nothing”

Final Truth

Tax is not as hard as it looks.

It is just:

✓ register
✓ declare
✓ submit

Let Me Leave You With This

Don’t wait for pressure.

Start early.

Because once you understand it once…

Every year becomes easy.
