Section 143(1) Intimation: Demand for ₹500–₹5,000 — Pay, Agree or Revise?
₹500–₹5,000 is the typical 143(1) demand for an arithmetical error, an incorrect claim, or a disallowed loss — with four paths: pay it, revise u/s 139(5) if you erred, rectify u/s 154 if the CPC erred, or appeal u/s 246A within 30 days.

A s.143(1) intimation from the Income-tax Act, 1961 — issued by the Centralised Processing Centre (CPC), Bengaluru after it processes your return — can raise a small demand of ₹500 to ₹5,000 for one of three things: an arithmetical error, an incorrect claim, or a disallowed loss; your options are to pay it, file a revised return u/s 139(5) if you filed wrong, a rectification u/s 154 if the CPC erred, or an appeal u/s 246A within 30 days. It is not a scrutiny notice and not an allegation — but a small demand ignored grows at 1% interest per month under s.220(2), so the decision, not the amount, is what matters.
What a s.143(1) intimation actually is
When you e-file, the CPC runs automated checks — arithmetic, TDS-credit matching, interest computation, and consistency against Form 26AS / AIS data — and issues an intimation with one of three outcomes: no change, refund, or demand. The demand arises only from adjustments the Act permits at this stage. Section 143(1)(a) allows three kinds:
If the adjustment falls outside these three categories, the CPC cannot make it at the 143(1) stage — it must go down the scrutiny path (s.143(2)). That boundary is your first line of defence: a "demand" built on a disallowed deduction that is actually correct is a CPC error, not a tax you owe.
When the intimation must arrive
The intimation must be sent within 9 months from the end of the financial year in which the return was furnished. For a return filed in FY 2026-27 (the AY 2026-27 filing season), the window runs to 31 December 2027. on the exact operative limit for your filing date — the statutory clock is tied to the year the return was furnished, not the assessment year.
Changed FY 2025-26: No change to s.143(1) mechanics — the three adjustment types and the 9-month intimation window are unchanged. The operational shift is volume: AIS/SFT-driven adjustments now account for the majority of small demands, so verify each line against your AIS before you respond.
Your four options for a small demand
The order to think in: is it my error → revise; is it CPC's error → rectify; do I dispute the whole demand → appeal; is it correct → pay. For a ₹500–₹5,000 demand, appeal is rarely worth it; rectify or pay are the practical paths.
Worked example: Nikhil's ₹5,000 TDS-mismatch demand
Persona: Nikhil, salaried, files ITR-1 for AY 2026-27 claiming TDS credit of ₹95,000 based on his Form 16.
The intimation: the CPC processes his return, matches against 26AS, finds only ₹90,000 of TDS, and raises a demand of ₹5,000 plus interest.
Step 1 — Diagnose. Nikhil logs in and compares his Form 16 against 26AS. He finds ₹5,000 deducted by his employer in the March quarter — deposited late, so the credit posted to 26AS after he filed. This is a timing gap, not a wrong claim.
Step 2 — Choose the path. This is not his error (the TDS is genuinely his); it is a data-timing issue, so a rectification (s.154) is the right route — not a revised return, not an appeal.
Step 3 — Rectify. He files a rectification under s.154 attaching the Form 16 and the 26AS extract showing the ₹5,000 posting. The CPC re-processes and nils out the demand.
Step 4 — If he had simply paid. Paying would have recovered the ₹5,000 only by claiming a refund later — a slower, avoidable path. And doing nothing would have attracted s.220(2) interest at 1% per month on the demand.
The takeaway: for a small demand, the first question is always whose error is it — the answer picks the remedy.
Frequently asked questions
1. What is a s.143(1) intimation?
An automated summary from the CPC issued after your return is processed, showing no change, a refund, or a demand — based only on arithmetical errors, incorrect claims, or disallowed losses.2. A demand of ₹2,000 appeared in my 143(1) — should I pay it?
Only if the adjustment is correct. Verify the reason first. If the CPC erred, rectify under s.154; if you erred, revise under s.139(5). If it is right, pay via challan ITNS 280 code 400.3. How do I pay a 143(1) demand?
Through e-filing → "Response to Outstanding Demand" → Pay, or directly via challan ITNS 280, major head 0021, code 400, quoting your PAN and assessment year.4. What is the time limit for a 143(1) intimation?
Within 9 months from the end of the financial year in which the return was furnished — for a return filed in FY 2026-27, latest by 31 December 2027. [VERIFY]5. Can the CPC adjust my refund against an old demand in 143(1)?
Yes — under s.245, a refund can be adjusted against an outstanding demand, which you will see reflected in the intimation. Check whether the old demand is time-barred.6. What happens if I ignore a small demand?
Interest under s.220(2) at 1% per month runs on the unpaid demand, and recovery action (including garnishing your bank account) can follow. Ignoring a small demand makes it larger.7. Can I appeal a 143(1) demand?
Yes, within 30 days before the CIT(A) under s.246A via Form 35. For a ₹500–₹5,000 demand, rectification or payment is usually the better route.---
