Section 143(1) of the Income Tax Act, 1961 lays out the process of preliminary assessment of income tax returns filed by taxpayers in India. Under this section, returns are processed by the Centralized Processing Centre (CPC) to check for arithmetical errors, input mismatches, tax calculation mistakes, and verification of tax payment or deductions. The CPC then issues an intimation, specifying any refunds due or additional taxes payable based on the assessment. If no discrepancies are found, the intimation will reflect that the return is accepted as filed. Section 143(1) intimation is not a scrutiny or detailed assessment, but simply an automated check to ensure accuracy and compliance. Taxpayers should review these intimations carefully and respond if any adjustments or demands are raised.

Read BioNavigating the Indian Income Tax system can feel confusing, especially when dealing with the different stages of processing your Income Tax Return (ITR). One of the most essential provisions you will come across is Section 143 1 of the Income Tax Act. This section deals with the processing of returns, automated intimation, and calculation of tax, penalty, or refund. Whether you are a salaried employee, self-employed, or investor, understanding what Section 143 1 is, what it means for you, and the practical implications in 2025 is crucial.
Section 143 1 of the Income Tax Act is the legal provision under which your Income Tax Return is initially processed by the Centralized Processing Centre (CPC). This process uses an automated system to verify arithmetic accuracy, identify mistakes, compute your final taxable liability, and finally issue an intimation if there are any discrepancies or a demand or refund.
Put simply, Section 143 1 intimation is the acknowledgment by the Income Tax Department that your filed return has been processed, and it informs you if you owe additional tax, are eligible for a refund, or if everything matches.
Did you know?
In assessment year 2025-26, over 1.2 crore taxpayers received Section 143 1 intimations within 30 days of filing their returns, thanks to new automated systems.
Section 143 1 involves an end-to-end automated process. After you file your ITR online, the following steps take place:
The intimation contains three variables:
You may get one of three scenarios:
People also ask:
Q: Is Section 143 1 intimation final?

Expert insight: According to CA Rajat Aggarwal, “The improved Section 143 1 process minimizes errors and provides better transparency for taxpayers. Always verify your intimation against your actual filings.”
When you receive a Section 143 1 intimation, here’s what you should do:
People also ask: Q: What is the deadline for responding to Section 143 1 intimation? A: Generally, 30 days from the date of intimation.
| Advantage | Limitation |
|---|---|
| Quick processing, often within 2-4 weeks | Only basic errors are caught, not complex |
| Automated, error-free calculations | Human level queries not entertained |
| Refunds issued faster than manual assessment | Can auto-adjust demand if no response |
| Taxpayer is informed promptly of any issue | Cannot replace regular assessment or audit |
| Easy to file rectification or respond online | Not a detailed scrutiny |
A common concern is when an incorrect demand is auto-adjusted if you don’t respond quickly. Always check your emails and the e-filing portal for updates to avoid this.
Did you know?
In 2025, rectification requests after 143 1 have been resolved within 10 days on average, reducing taxpayer anxiety.
| Feature | Section 143 1 Processing | Scrutiny Assessment (143 2/143 3) |
|---|---|---|
| When it happens | After return is filed | On selection, based on risk |
| Mode | Fully automated, no human | Involves human verification |
| Purpose | Spot arithmetic or obvious errors | Examine correctness, in-depth |
| Opportunity to respond | Only for adjustments | Notices and regular hearings |
| Timeline | Usually under 30 days | Can take several months |
| Consequence | Refund, intimation, or demand | Can lead to order, penalty |
People also ask: Q: What happens after Section 143 1? A: Once processed, unless selected for scrutiny, your return is treated as assessed for the year.
As a salaried taxpayer, I filed my ITR 1 for AY 2025-26 in early July. Within 10 days, I received an SMS and email about a Section 143 1 intimation.
When I opened the PDF, I noticed a mismatch in TDS credit. The tax department missed one Form 16 issued by my former employer. I logged into the portal, checked my Form 26AS, and realized the TDS was not reflected there since the employer delayed reporting.
Through the e-portal, I raised a rectification request, attached my Form 16, and within a week, the intimation was revised, nullifying the earlier demand.
This fast and transparent process gave me confidence that minor errors can be quickly fixed in 2025. Always keep your documents scanned and ready for any follow-up.
By spending a few extra minutes cross-checking, you can avoid unnecessary demands and correspondence.
Expert insight: Financial planners recommend using reliable online tax filing portals that cross-check your claims against real-time data from multiple sources for fewer mistakes.
Per updated rules for AY 2025-26:
Always keep a digital and physical copy for at least 6 years for any future reference, loan processing, or queries.
Using online tax marketplaces, you can compare the refund efficiency and tax support services of various companies, ensuring faster help in case of errors.
Did you know?
In 2025, more than 95 percent of refunds were processed within one week after 143 1 intimation.
Section 143 1 of the Income Tax Act deals with automated processing of your ITR. You will receive an intimation if there is any difference between what you declared and what is available in the department records. Most queries are resolved quickly online, and you should always respond promptly to avoid demand adjustments.
Q1: Is Section 143 1 an assessment order?
No. Section 143 1 is not a final assessment. It is an automated preliminary processing of your ITR, not a detailed scrutiny.
Q2: What should I do if my Section 143 1 has a demand?
Double-check the calculation. If wrong, file a rectification online; if correct, pay the demand to avoid penalties.
Q3: Do all taxpayers get Section 143 1 intimation?
Yes, every electronically filed ITR is processed under Section 143 1, even if there is no difference found.
Q4: Can I ignore a 143 1 intimation if there’s no refund or demand?
You should still download and keep a copy for your records, but no other action is needed if ‘No Demand, No Refund’.
Q5: Is it necessary to reply to 143 1 if everything matches?
No action required if the intimation matches your return, but keep it safe.
Tip: Comparing services on online tax marketplaces helps you choose platforms that offer real-time WhatsApp or phone support for Section 143 1 related queries.
