Decision table

How to apply the rule

Use the portal statement as a starting point, not a substitute for books and supporting documents. Tax reporting follows the legal character of an amount: a bank credit may be income, a transfer, a loan, a reimbursement or a sale consideration. Label the amount before deciding its tax treatment.

Keep a year-specific working paper. The transition on 1 April 2026 means the filing date alone does not identify the governing statute. Record the income period, the applicable Act, the return or proceeding, the tax credit and the portal service used.

A good compliance file lets another professional reproduce the result. Include the taxpayer’s figure, the department or third-party figure, the difference, the explanation and the evidence reference.

For Form 26AS vs AIS vs TIS, first identify the legal or contractual relationship, then separate the amount, event and deadline. Use one chronology across the portal, institution and supporting records. This prevents a correct fact from being submitted under the wrong year, account, policy clause or complaint route.

Practical example

A freelancer has ₹8 lakh of receipts in a payment account, ₹80,000 of TDS in Form 26AS and ₹9 lakh in AIS because one payer reported gross billing including a reversed invoice. The return should reconcile books, actual receipts and TDS—not copy the largest portal number.

Action checklist

• Download all three statements after major deductor filings have been processed.
• Reconcile TDS deductor-wise and challan-wise.
• Match AIS transaction categories to source statements.
• Explain why gross transaction values differ from taxable income.
• Check income omitted from portal statements.
• Retain the dated reconciliation used for filing.

Evidence and document checklist

• Form 26AS PDF or download
• AIS detailed report and feedback status
• TIS summary
• TDS certificates and invoices
• Bank and broker statements
• Filed return and computation
• Deductor correction correspondence

Common mistakes

• Checking only Form 26AS for income
• Checking only AIS for tax credit
• Using TIS as a legal determination of taxable income
• Ignoring timing differences and joint ownership
• Claiming TDS against the wrong year
• Forcing a return to match a duplicated item

Red flags

Escalation route

Correct TDS/TCS through the deductor or collector. Submit AIS feedback for information errors. Use the appropriate return, rectification, grievance or notice-response route for the actual tax consequence.

When escalating, include the original complaint, acknowledgement, concise chronology, disputed amount, rule or clause relied upon and the exact relief requested. Do not send passwords, PINs, OTPs or unrelated identity documents.
