Section 143(1)(a) — Notice for Proposed Adjustments

Strategic response to prima facie adjustment notices raised by the Centralised Processing Centre before your return is finally processed.

Quick answer

A notice under Section 143(1)(a) flags limited, objective mismatches the CPC has found in your return — arithmetical errors, disallowed loss carry-forwards, or income visible in Form 26AS/AIS that wasn't reported. You get 30 days to respond; if you don't, the proposed adjustment is made automatically. We review each flagged item, confirm whether it is genuinely correct, and file the response through the e-Proceedings portal.

What we cover

What Section 143(1)(a) covers

The CPC can only make limited, objective adjustments at this stage — not debatable or interpretational ones — which shapes how we respond.

  • Correction of arithmetical errors in the return
  • Disallowance of an incorrect claim apparent from the return itself
  • Loss carry-forward disallowed for late-filed prior returns
  • Expenditure disallowed in the audit report but not added back
  • Income from Form 26AS or AIS not reflected in the return
  • Deciding whether each proposed adjustment is factually correct
  • Filing the response within the 30-day window

Why choose us

Why a timely, accurate response matters

What sets our approach apart.

30 days, no extensions by default

If no response is filed within 30 days, the proposed adjustments are confirmed automatically.

Adjustments feed the demand

Adjustments increase computed income and can trigger an unexpected tax demand or a reduced refund.

Debatable issues shouldn't be adjusted here

Only prima facie, objective mismatches are valid under this section — genuinely disputed claims deserve a reasoned pushback.
