ITR-4 Document Pack Before Filing: AIS, TIS, Form 26AS, Bank Interest and Presumptive Books

By Ravi Sisodia · Reviewed by CA Divyanshu Sengar · Updated 5 October 2026

A clean ITR-4 file starts with evidence, not portal entry. The preparer should reconcile AIS/TIS, 26AS, bank interest, presumptive receipts, GST data, deductions and taxes before opening the return.

Finin2min 2-Minute Summary

• AIS contains broader information than Form 26AS, while 26AS remains important for TDS/TCS and tax-credit reconciliation.
• Bank interest should be split by account/product and mapped to the correct income head.
• Presumptive receipts need a defensible bridge from bank/GST/invoice data to the section 44AD/44ADA/44AE figure used.
• Personal transfers, loan receipts and capital introductions should not be misclassified as business turnover merely because they appear in a bank account.
• Keep the final reconciliation pack with the return acknowledgement and tax-payment evidence.

Create one evidence index before computation

Download AIS/TIS, 26AS, bank statements, interest certificates, GST returns where relevant, sales/receipt summary, prior-year return, challans and deduction proofs. Give each document a period and source.

Where AIS shows a transaction not belonging to the taxpayer or not taxable in the way displayed, investigate and use the portal feedback mechanism where appropriate rather than silently ignoring it.

Receipts-to-income reconciliation

Prepare a bridge from gross business/professional receipts to the presumptive base. Explain refunds, GST included/excluded treatment, pass-through amounts and non-business bank credits.

For professional receipts, match TDS certificates/26AS to the gross amount and identify timing differences.

Bank-interest reconciliation

List savings, FD/RD, sweep, business-current-account interest and any tax-deducted interest separately. Tally the list to AIS and bank certificates so a small account is not missed.

Classify the income based on facts rather than whichever schedule is easiest to fill.

Control example: one AIS item appears twice in the bank pack

A common reconciliation problem arises when a bank reports interest in AIS at branch/PAN level while the taxpayer's own certificate lists the same amount across two deposits. If the preparer totals AIS and certificate amounts independently, income is doubled. Mark each external-data item to the underlying account/deposit and use one gross-income source as the accounting truth, with AIS/26AS as verification layers.

The same discipline applies to TDS: claim the credit from the official statement, but do not infer the gross receipt solely by reverse-calculating from TDS. Build the gross receipt from books/invoices/bank evidence and explain any timing difference.

• De-duplicate AIS items against source statements.
• Use source ledger for gross receipts.
• Maintain a reconciliation note for every unresolved information mismatch.

Questions readers commonly ask

Are AIS and 26AS the same?

No. AIS contains broader information; 26AS remains central for tax-credit items.

Do bank deposits equal turnover?

No. Classify deposits by source.

Should GST turnover equal ITR receipts exactly?

Not always, but material differences should be explained and documented.

Why retain the pack after filing?

It supports later verification, notice response or correction.
