Intimation under 143(1): How to Read Demand or Refund Adjustment
An intimation-reading framework comparing returned income, processed adjustments, tax credit, interest, fee, demand, refund and response options.
An intimation is a line-by-line processing result. The first question is not ‘pay or appeal?’ but ‘what changed from the filed return?’
The Income-tax Act, 2025 took effect on 1 April 2026. FY 2025–26 and AY 2026–27 remain governed by the Income-tax Act, 1961, including the notified AY 2026–27 ITR forms. Tax year 2026–27 beginning 1 April 2026 is governed by the 2025 Act and the Income-tax Rules, 2026. Legacy section numbers and forms should therefore be used only for the period to which they legally apply.
AY 2026–27 intimations remain under the 1961 Act processing framework even if issued after 1 April 2026.
The intimation compares return figures with CPC-processed figures and identifies adjustments and tax computation.
Tax-credit mismatch, arithmetical errors, inconsistent claims and specified return information can create demand or reduced refund.
What the taxpayer should understand
- The Income-tax Act, 2025 took effect on 1 April 2026. FY 2025–26 and AY 2026–27 remain governed by the Income-tax Act, 1961, including the notified AY 2026–27 ITR forms. Tax year 2026–27 beginning 1 April 2026 is governed by the 2025 Act and the Income-tax Rules, 2026. Legacy section numbers and forms should therefore be used only for the period to which they legally apply.
- AY 2026–27 intimations remain under the 1961 Act processing framework even if issued after 1 April 2026.
- The intimation compares return figures with CPC-processed figures and identifies adjustments and tax computation.
- Tax-credit mismatch, arithmetical errors, inconsistent claims and specified return information can create demand or reduced refund.
- A proposed prima facie adjustment may have a response opportunity before final processing.
- After final intimation, the remedy may be payment, demand response, rectification or appeal depending on the error.
The five-point review
| Check | What to examine |
|---|---|
| Return | Acknowledgement and original computation. |
| Adjustment | Income, deduction, loss or tax-credit difference. |
| Tax | Rate, rebate, interest and fee. |
| Outcome | Demand, refund or no change. |
| Remedy | Agree, disagree, rectification, appeal or payment. |
Practical example
A taxpayer claimed ₹1 lakh TDS, but CPC allowed ₹70,000 because Form 26AS showed less. The correct first step is to identify whether the deductor statement or return claim is wrong, not to file a generic rectification immediately.
How to apply the framework
Create a returned-versus-processed comparison by line.
Do not select ‘demand is correct’ merely to access payment if the liability is disputed; the portal warns that the response can become irreversible.
Filing-control workflow
Fix the tax period and statutory route
Identify the financial year, assessment year or tax year before using any threshold, form or section. Review return, adjustment and tax together. A form filed in June 2026 for AY 2026–27 remains an old-Act filing, while an event occurring after 1 April 2026 can fall under the new Act.
Reconcile the commercial evidence
Start from contracts, invoices, bank statements, payroll, broker records, property documents and statutory certificates. Then reconcile AIS, TIS, Form 26AS, ITR schedules, tax payments and prior returns. Portal information can contain gross values, timing differences or reporting errors and should not replace primary evidence.
Test the live filing result
Review validation messages, selected regime, form acknowledgements, loss schedules, tax-credit matching and processed intimation. Preserve the filed JSON or form, computation, supporting schedules, transaction IDs and any correction request. A saved draft or payment debit is not proof that the statutory task is complete.
Implementation checkpoint
Before treating the filing step as complete, verify the live portal or processed outcome. Confirm the form and regime, taxable income, losses, tax credit, payment mapping, deduction schedule and acknowledgement. Record any remaining mismatch, responsible person and correction deadline. This check prevents a technically submitted return from preserving the wrong tax result.
Action checklist

Warning signs
- Reading only the last page
- Demand accepted without comparison
- New deduction attempted through rectification
- Appeal deadline ignored
- Refund reduction not traced
Finin2min takeaway
Advanced tax filing is a classification and reconciliation exercise. A lawful result depends on the correct period, taxpayer, form, regime, evidence and portal outcome—not a deduction label copied from a checklist.
