An intimation under Section 143(1) of the Income Tax Act is a message from the Income Tax Department after it processes your ITR. It comes from the CPC office in Bengaluru. It tells you one of three things: no change, a refund, or a demand. The department must send it within nine months from the end of the financial year in which you filed your return. It is not a scrutiny notice. For most people, it’s routine.
If you run a business out of Cyber City, Udyog Vihar, or Golf Course Road and just got an email titled “Intimation under Section 143(1),” take a breath first. This happens to almost every taxpayer in India. It is simply how the Income Tax Department confirms your return was processed. This guide, reviewed by CA Varun Gupta, Founder of Gupta Varundeep & Co. (GVC Audit), walks you through what it means and exactly what to do about it.
What Is an Intimation Under Section 143(1)?
Every income tax return filed in India goes through a basic check. This check is called processing under Section 143(1). A computer system at the Centralised Processing Centre (CPC) in Bengaluru compares your return with the department’s own records things like your Form 26AS, AIS (Annual Information Statement), and TDS data. Once this check is done, you get an intimation. It shows your income and tax as you reported it, next to the figure the department calculated. If both match, there’s nothing to do. If they don’t, the intimation tells you why. This is not a scrutiny notice. No tax officer has reviewed your file by hand. It is simply the system’s summary of your return.
Why Does Section 143(1) Exist?
The government needs a fast way to close out millions of tax returns every year. Section 143(1) does three things:
- Catches basic errors, like a wrong addition or a deduction claimed above the legal limit
- Confirms your final tax position refund, demand, or no change
- Gives you official proof that your return has been processed
Without this step, no taxpayer would know if their return was accepted or if something needs fixing.
Who Gets an Intimation Under Section 143(1)?
Everyone who files an income tax return can receive one. This includes:
- Salaried professionals
- Business owners and freelancers
- Startups and private limited companies
- Partnership firms and LLPs
- NRIs with Indian income
If you filed a return this year, expect an intimation once processing is complete — whether you run a two-person consultancy on Sohna Road or a growing SaaS company in Cyber City.
How Section 143(1) Processing Works
- You file your ITR and complete e-verification (Aadhaar OTP, net banking, or physical ITR-V).
- Your return goes to the CPC in Bengaluru for automated processing.
- The system checks your figures against Form 26AS, AIS, and TDS records.
- If it finds a mismatch that needs your input, it sends a prior communication under Section 143(1)(a) and gives you 30 days to respond before making any change.
- Once processing is complete, you get the final intimation by email and SMS.
- If a refund is due (above ₹100), it’s credited to your bank account. If a demand is raised, you’ll get a notice of demand along with it.
Common Reasons You Might Get a Demand or Mismatch
- TDS shown in your return doesn’t match Form 26AS or AIS yet (often a timing issue the deductor filed late)
- Interest income or other earnings visible in AIS but missing from your return
- A simple calculation error
- A deduction claimed above the allowed limit (for example, over ₹1.5 lakh under Section 80C)
- Certain losses or deductions disallowed because the return was filed after the due date
Most of these are fixable. Very few point to anything serious.
The Three Types of Intimation Outcomes
| Outcome | What It Means |
|---|---|
| No Demand, No Refund | Your Income Tax Return matches the Income Tax Department's records. No further action is required. |
| Refund Due | You have paid more tax than required. The eligible refund will be credited to your registered bank account, along with applicable interest if there is a delay. |
| Demand Due | The Income Tax Department believes additional tax is payable. Review the demand carefully before making any payment, as it may result from a mismatch in records rather than an actual tax liability. |
143(1) vs. 143(1)(a) vs. 143(2) vs. 143(3) Know the Difference
| Section | What It Is | Who Handles It | Time Limit |
|---|---|---|---|
| 143(1) | Automated summary processing of the Income Tax Return to identify arithmetic errors, tax credit mismatches, or incorrect claims. | Centralized Processing Centre (CPC) – System Based | Within 9 months from the end of the financial year in which the return is filed. |
| 143(1)(a) | Prior intimation issued before making adjustments for mismatches or incorrect claims detected during return processing. | Centralized Processing Centre (CPC) – System Based | 30 days for the taxpayer to submit a response. |
| 143(2) | Scrutiny notice issued when the Income Tax Department selects the return for detailed verification. | Assessing Officer | Within 3 months from the end of the financial year in which the return is filed. |
| 143(3) | Final scrutiny assessment order issued after examining documents, explanations, and evidence submitted by the taxpayer. | Assessing Officer | Within 12 months from the end of the relevant Assessment Year. |
In short: 143(1) is routine and automated. 143(2) is a genuine scrutiny notice that needs a proper response with your CA.
A Realistic Example
Picture a small IT services company based in Udyog Vihar. It files its return claiming TDS credit based on its own accounting records. One client the company paying for the services files its TDS return a little late. So when CPC processes the IT company’s return, part of the TDS credit isn’t visible yet in Form 26AS.
Result: the intimation shows a demand, even though no tax is actually owed. The fix isn’t to pay up it’s to confirm the TDS appears correctly once the client’s filing catches up, then file a rectification request under Section 154 if needed. This kind of mismatch is common and easy to resolve with the right documentation.
What You Should Do When You Get an Intimation
- Download it from the e-Filing portal: e-File → Income Tax Returns → View Filed Returns → Download Intimation Order.
- Open it. The password is your PAN in lowercase, followed by your date of birth in DDMMYYYY format (no spaces). Example: PAN ABCDE1234E, DOB 1 Jan 2000 → abcde1234e01012000. Companies use their date of incorporation.
- Check the basics your name, PAN, and the assessment year to confirm it’s really about your return.
- Compare the two columns: “as provided by you” versus “as computed by the department.”
- Cross-check every difference against your Form 26AS and AIS.
- Then act, based on the outcome:
- No change save the PDF for your records.
- Refund track it on the e-Filing portal or NSDL. Confirm interest under Section 244A is included correctly.
- Demand you agree with pay it through Challan 280, selecting “Tax on Regular Assessment (Code 400).”
- Demand you disagree with file a rectification under Section 154, or respond directly under “Pending Actions → Response to Outstanding Demand.” If needed, you can appeal under Section 246A within 30 days.
Key Deadlines to Remember
- Issuing the intimation: Within 9 months from the end of the financial year in which you filed the return. Example: a return for FY 2024-25, filed in July 2025, falls under FY 2025-26 (ending 31 March 2026) so the intimation can arrive any time up to 31 December 2026.
- Responding to a 143(1)(a) mismatch alert: 30 days.
- Paying a demand: 30 days from the notice.
- Filing a rectification (Section 154): Within 4 years from the end of the financial year in which the order was passed.
- Filing an appeal (Section 246A): Within 30 days of the order.
Documents to Keep Ready
- The intimation PDF
- Your filed ITR and computation
- Form 26AS and AIS
- Form 16 or 16A
- TDS certificates
- Advance tax and self-assessment tax challans
- Bank statements, if any income figure is disputed
What Happens If You Ignore a Demand
Ignoring a valid demand isn’t a safe option. It leads to:
- Interest under Section 220(2) 1% per month on the unpaid amount
- A penalty under Section 221, which can go up to the full tax amount owed
- Refund adjustment under Section 245 future refunds may be used to settle the old demand
- Recovery action, including bank account attachment, in serious cases
Most of this is avoidable by simply reviewing and responding within the deadline.
Benefits of Getting Your Intimation Reviewed Early
- Refunds are confirmed and tracked faster
- Genuine mismatches (like TDS timing issues) are caught before they turn into penalties
- You avoid paying a demand you don’t actually owe
- You have clean, verified records useful when applying for business loans or investor due diligence
Common Mistakes to Avoid
- Ignoring the email because it “sounds like a notice”
- Paying a demand without checking if it’s correct
- Not reconciling Form 26AS and AIS before filing in the first place
- Missing the 30-day window to respond to a 143(1)(a) alert
- Assuming an intimation is the same as a scrutiny notice
Recent Updates You Should Know About
- Finance Act 2025 added a new check under Section 143(1)(a): the department can now flag inconsistencies between your current return and your return from a previous year for example, a credit claimed last year that doesn’t carry through consistently. The exact rules on how this will be applied are still being finalised by the CBDT.
- CBDT Circular No. 10/2025 allowed processing of certain electronically filed returns (up to 31 March 2024) that were wrongly marked invalid by CPC, with intimations to be issued by 31 March 2026.
- Income-tax Act, 2025, effective from 1 April 2026, replaces the 1961 Act. The equivalent of Section 143(1) is Section 270 in the new Act, and the same 9-month deadline continues. Returns for FY 2025-26 still fall under the old Act, so this transition matters mainly for future filings.
We track these updates closely so our clients never file or respond based on outdated rules.
