What is an intimation u/s 143(1)?

An intimation u/s 143(1) is a communication issued by the Centralised Processing Centre (CPC) after processing your Income Tax Return. It compares the information reported in your return with the records available with the Income Tax Department.

The intimation may confirm that your return has been processed without any changes or that a refund is payable to you. It may also show an additional tax demand, a mismatch in TDS or TCS credit, differences in income reported in AIS or Form 26AS, or an adjustment relating to a deduction or exemption.

It may further highlight a tax challan mismatch or the adjustment of your refund against an outstanding tax demand from an earlier year.

In simple words, an intimation u/s 143(1) informs you whether your ITR has been accepted as filed or whether any action is required from your side.

Section 143(1) and Section 270(1) Comparison

Under the Income Tax Act, 1961, processing of return is covered under Section 143(1). Under the Income-tax Act, 2025, the corresponding provision is Section 270(1).

For notices and returns relating to periods governed by the Income Tax Act, 1961, Section 143(1) will continue to apply. For the new Act, Section 270(1) is the corresponding reference.

Why You Should Not Ignore Income Tax Notice Section 143(1)?

Many taxpayers think that a Section 143(1) intimation is only an information notice. That is not always true. If the notice shows a tax demand or incorrect adjustment, delay can increase compliance issues.

You should get the notice checked because

• A wrong demand may remain outstanding on the portal
• Future refunds may get adjusted
• Interest may increase if demand is payable
• TDS credit may remain unmatched
• Wrong income addition may affect your tax records
• An incorrect reply may lead to further notice
• Delay may create unnecessary follow-up with the department.

Tax Intelligence helps you avoid confusion by checking the notice carefully and filing the right response online.
