Income Tax Notice 143(1)(a) is one of the most common notices issued by the Income Tax Department during the initial processing of your return. Many taxpayers get worried when they see this intimation, but in most cases it is only a communication about a mismatch or a proposed adjustment in the Income Tax Return filed for the year. The Central Processing Centre checks the return using automated systems and compares the details with Form 26AS, AIS, TIS and other data available with the department. If any difference is found in income, deductions or tax credit, the system issues a notice under section 143(1)(a) asking the taxpayer to confirm or correct the information. Timely review of the notice and a proper response helps avoid unwanted tax demand, interest and further complications.
What is Income Tax Notice 143(1)(a)
Income Tax Notice 143(1)(a) is an intimation that informs you about proposed adjustments detected during the processing of your filed return. The department compares the figures reported by you with the information already available in its records. If a mismatch is detected, the system suggests an adjustment and seeks your confirmation. These adjustments may relate to income reported, deductions claimed, TDS, or any inconsistencies between Form 16, Form 26AS and AIS. It does not mean scrutiny assessment. It is only a preliminary review of your return. You are required to respond online by either agreeing, partially agreeing, or disagreeing with the proposed changes. A correct and timely response ensures smooth processing of your return and prevents unnecessary tax demand.
Types of Intimation under section 143(1)
No Demand No Refund
The computation done by the department matches the figures filed in your return. There is no tax payable and no refund due. This confirms that the return has been processed without any change.Refund Due
The department finds that tax paid or TDS available is more than the final tax liability. A refund is generated and credited to your bank account after processing.Demand Payable [143(1)(a)]
The department identifies a difference that increases your tax liability. This may happen due to mismatch in income, incorrect deductions, or lower TDS credit. A tax demand is raised along with interest wherever applicable.
These are the 3 outcomes that a taxpayer may receive after the Income Tax Department completes the processing of the return under section 143(1).

What Happens After Submission of Response
Once you submit your response to Notice 143(1)(a), the Income Tax Department reviews your remarks and verifies any supporting documents uploaded. The system then recalculates your income, deductions and tax based on the information you have provided. If your clarification is accepted, the proposed adjustments are removed and the return is processed as originally filed. If some adjustments still stand, the department finalises the computation accordingly. After completing the review, you receive a revised intimation under section 143(1) that shows the final tax position, which may result in a refund, no change or a tax demand. The matter is normally treated as closed once this final intimation is issued.
Consequences of Not Responding in Time
- The system assumes that you agree with all proposed adjustments.
- Additional income is added to your return based on department records.
- Tax demand may be raised due to revised computation.
- Interest under section 234A, 234B and 234C may apply.
- Refund, if any, may get reduced or cancelled.
- The notice may lead to further communication or follow up from the department.
- You may face difficulty in future return processing if mismatches remain unresolved.
