Understanding Section 143(1): Intimation Notices and Taxpayer Guidance

What is an Intimation Under Section 143(1) – And Why You Shouldn’t Ignore It

If you've filed your Income Tax Return (ITR), chances are you’ll soon hear back from the Income Tax Department — not with a phone call or a visit, but through a quiet little document called an intimation under Section 143(1).

What Exactly Is an Intimation Under Section 143(1)?

Think of it as a computer-generated response after your return is processed. It summarises:

What you declared as income, deductions, and taxes
What they have on record — via your Form 26AS, TDS statements, and other sources
Whether there’s agreement or mismatch
Whether you’re due a refund, owe more tax, or everything matches up

It's not an audit. It’s more like a reconciliation summary — an automated comparison of what you filed versus what the system computes.

Why Do You Receive It? Three Common Scenarios

You’ll typically get an intimation if:

1. You’re Due a Refund

If your tax payments (TDS, advance tax, etc.) were more than your final tax liability, the excess is refunded — usually only if it's more than ₹100.

2. You Owe More Tax

If your tax payments fell short, the department will let you know how much more is due. This notice includes a challan for easy payment.

3. Everything Matches

Sometimes, there's nothing to worry about — the numbers match perfectly. In such cases, you may not even get a separate intimation. Your ITR-V (verification) acknowledgment is enough.

When Can You Expect It?

The Income Tax Department sends this intimation within 1 year from the end of the financial year in which you filed your return.

For example: If you filed your return for FY 2023–24 on July 10, 2024, the intimation can be issued anytime up to March 31, 2026.

If you don’t receive it by then, your ITR-V acknowledgment effectively becomes final.

How Will You Receive the Intimation?

Email: From intimations@cpc.incometax.gov.in to your registered ID
SMS: On your registered mobile number, asking you to check your email or login to the e-filing portal

What Should You Check in the Intimation?

Carefully verify:

Your details (PAN, name, AY)
Income declared vs. income computed
Deductions claimed (under Section 80C and others)
TDS/TCS/self-assessment tax credits
Any relief claimed (Sections 89, 90, 90A, 91)
Final outcome: refund, tax due, or no change

What to Do After Receiving It?

If You’re Okay With It:

Refunds (above ₹100) will be processed automatically. Just wait for the credit.
No dues? No response required. Just keep the intimation safely.

If There’s a Tax Demand:

Review the calculation.
If it makes sense, pay promptly using the attached challan to avoid interest or penalty.

If Something Seems Off:

File a rectification request:
- Log in > “Services” > “Rectification Request”
You can also consult a CA or tax expert if you’re unsure.

How Long Before Refund Is Issued?

If you e-verified your return online, refunds typically arrive within 20 to 45 days.
If you sent in the ITR-V physically, expect some delay before processing begins.
