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.
THIS IS JUST TO EXPLAIN SO YOU WOULD UNDERSTAND CLEARLY, I Will give another answer to explain exactly what you are going to do.

If you have been Searching for How to File Your Personal Income Tax in Anambra State (here’s a Simple Step-by-Step Guide Anyone Can Follow)
And, as your Financial Literacy Advocate.. Let me explain this with a Simple Story in a way you will never forget.
Imagine Mama Ngozi travels from her village to Onitsha.
As she enters the market, she hears people shouting:
She gets confused…
If you feel like Mama Ngozi right now… relax.
Let me break it down for you step by step.
First Thing You Must Understand
You are not paying tax for 2026.
You are declaring the money you made from January to December 2025
That is how tax works.
You pay after the year has ended, not while the year is still running.
Secondly, ASIN means Anambra State Identification Number.
Here’s how to file your Personal Income Tax in Anambra
STEP 1: Go to Anambra State Tax Website
Open Google and type:
Anambra State IRS
Then open the official website: tax.services.an.gov.ng
STEP 2: Create Your ASIN Number
This is very important.
ASIN is like your tax identity in Anambra State
When you enter the website:
Click on Create ASIN
Choose:
Individual (for personal income tax)
Enterprise (for small business)
Corporate (for companies)
If you are working or doing business personally, choose Individual
STEP 3: Enter Your NIN
When you click Individual:
Enter your NIN
Your details will appear automatically:
Name
Phone number
Address
Picture
Just complete the remaining form and create a password
STEP 4: Login to Your Account
Go back to:
tax.services.an.gov.ng
Click Login
You can login using:
Your ASIN number OR
Your Email
Enter your password and login.
STEP 5: Click “File Annual Return”
After logging in:
Click File Annual Return
VERY IMPORTANT (because this is Where Many People Make Mistake)
If you earn monthly: ₦80,000 per month
Do NOT type ₦80,000
Multiply it:
₦80,000 × 12 = ₦960,000 or multiply it by the number of months that you worked or total money earned.
That is your annual income
STEP 6: Fill Other Details
You will see:
Your income
Rent
Other earnings
Fill what applies to you
The system may also ask for:
Landlord name
Landlord ASIN
Phone number
If you don’t have it:
Just type NIL
And move on.
STEP 7: Select Your Profession
You will see options like:
Trader
Teacher
Developer
Choose your work
STEP 8: Tax Relief (Optional)
You may see:
Pension
Insurance
Mortgage
If you don’t have any:
Skip it
STEP 9: Submit and Download
After everything:
Click Submit
Then:
Download your Acknowledgement Slip
Keep it safe, this is your proof
Now, as your Financial Literacy Advocate, let me tell you a Secret That Many People Don’t Know
and here’s the truth…
This whole process can take you less than 10 to 20 minutes minutes
Yes… less than 10 minutes.
The problem is not difficulty…
The problem is lack of understanding. And lack of Orientation and awareness from the Government.
But here’s the one deep truth you must know
Tax is not your enemy.
Ignorance is the real problem.
Because:
If your income is small, you may pay little or nothing
But if you don’t file, penalty will follow.
If you still don’t understand anything…
