What Is Processing of a Return under Section 270?
For returns governed by the Income-tax Act, 2025, Section 270 provides the statutory mechanism for processing the return. It broadly performs the role that Section 143(1) performed under the Income-tax Act, 1961.
Processing is primarily a limited statutory computation exercise. The total income or loss shown in the return may be adjusted only for matters specifically authorised by Section 270, after which tax, interest and fee are computed and any amount payable or refund due is determined.
Permissible Adjustments under Section 270
Section 270(1)(a), as applicable after the Finance Act, 2026 amendments, permits specified adjustments while processing a return. These include:
- an arithmetical error in the return;
- an incorrect claim apparent from information in the return;
- an inconsistency in the return with information in a preceding tax-year return, where prescribed;
- disallowance of a loss claimed where the return for the tax year in which the loss arose was furnished after the statutory due date;
- disallowance of expenditure or increase of income indicated in an audit report but not taken into account in computing the returned total income; and
- disallowance of specified deductions where the return was furnished after the due date, to the extent provided by the Act.
What Is an "Incorrect Claim Apparent from the Return"?
Section 270 explains that an incorrect claim apparent from information in the return includes, among other things, an entry inconsistent with another entry in the return, a claim lacking information required by the Act to substantiate it, or a deduction exceeding a specified statutory monetary or percentage limit.
The provision is therefore designed for adjustments evident from the return and statutory data used for processing. It is not a general substitute for a full investigation into disputed facts or evidence.
Opportunity to Respond before an Adjustment
Before an adjustment under Section 270(1)(a) is made, the assessee must be informed of the proposed adjustment in writing or electronically. The response received must be considered. If no response is received within 30 days from issue of the communication, the adjustment may be made and the intimation sent.
Time Limit for Section 270 Intimation
Section 270(4) provides that an intimation under Section 270(1) cannot be sent after the expiry of nine months from the end of the financial year in which the return is made.
For example, if a return is furnished during FY 2026-27, the ordinary statutory period is counted from 31 March 2027, subject to any special provision, valid extension or other law applicable to the particular case.
Section 270 Processing Is Not Detailed Scrutiny
Processing of a return does not ordinarily involve examination of books of account, witnesses or disputed evidence. The Income-tax Act, 2025 separately provides for a scrutiny notice where the prescribed authority considers it necessary or expedient to ensure that income has not been understated, loss has not been overstated or tax has not been underpaid.
| Particular | Summary processing / intimation | Scrutiny assessment |
|---|---|---|
| Nature | Limited statutory processing | Detailed examination |
| Evidence | Primarily return and statutory processing information | Books, documents and evidence may be examined |
| Adjustments | Only those permitted by the processing provision | Issues may be examined on merits under the scrutiny framework |
| Taxpayer participation | Response to proposed adjustment where required | Notices, submissions and evidence may be required |
| Result | Intimation | Assessment order |
Legacy Section 143(1) of the Income-tax Act, 1961
Section 143(1) continues to matter for returns, assessments and proceedings that remain governed by the Income-tax Act, 1961 under the repeal-and-savings provisions of the Income-tax Act, 2025.
Its essential character is similar: the return is processed, prescribed adjustments may be made, tax and interest are computed, and an intimation may be generated showing demand or refund.
Important correction: the applicable statutory time limit under the current text of legacy Section 143(1) is also nine months from the end of the financial year in which the return is made, not one year.
Rectification, Scrutiny and Later Proceedings
An intimation from return processing has legal consequences, but it should not be equated with a comprehensive scrutiny adjudication of every issue in the return. Other proceedings may still be available where their independent statutory conditions are satisfied.
A mistake apparent from the record may also be capable of rectification under the applicable rectification provisions. Taxpayers should use the current e-filing procedure and the provision applicable to the relevant tax year.

Frequently Asked Questions
What is the current equivalent of Section 143(1)?
For tax years governed by the Income-tax Act, 2025, the principal return-processing provision is Section 270.
Is processing of a return the same as scrutiny assessment?
No. Processing is limited to adjustments permitted by statute. Scrutiny is a separate, more detailed examination.
How long does the taxpayer have to respond to a proposed adjustment under Section 270?
The statute provides a 30-day response period from issue of the communication.
What is the time limit for an intimation under Section 270?
Nine months from the end of the financial year in which the return is made.
Does legacy Section 143(1) still have relevance?
Yes. It continues to apply where the Income-tax Act, 1961 governs the relevant earlier year or saved proceeding.
Is an intimation conclusive on every issue?
No. It is legally effective for the processing it records, but it is not equivalent to a detailed scrutiny assessment and does not, by itself, conclusively adjudicate every possible issue in the return.
