About Our Service

What is Section 143 1 a of Income Tax Act?  

Section 143 1 a of Income Tax Act allows the Income Tax Department to make prima facie adjustments while processing your Income Tax Return (ITR). It is not a final assessment but a preliminary check where discrepancies, mismatches, or excess claims are flagged.

A notice under this section is generally issued when:

  • There are arithmetical errors in the ITR.

  • Incorrect claims are made.

  • Losses are wrongly carried forward.

  • Expenses or deductions are disallowed.

  • Income mismatch is found with Form 16, Form 16A, or Form 26AS.

Taxpayers have 30 days to reply to such notices, failing which the adjustments are confirmed, and extra tax demand may be raised.Professional assistance for notice u/s 143(1)(a)

Peace of Mind

Professional handling of the communication ensures accuracy in your response and reduces the stress of future tax complications.
