Income Tax Return Filing Guide for AY 2026–27

Who should file an Income Tax Return?

The requirement depends on total income, residential status, income sources, business or professional activities, specified transactions, foreign assets and other prescribed conditions. No final tax payable does not necessarily mean no return is required.

• Claim an eligible income-tax refund.
• Carry forward eligible losses, subject to the filing conditions and time limits.
• Maintain declared-income records for lending, visa or other documentation requirements.
• Report capital gains and any required foreign income or asset disclosures.

Which ITR form should you file?

The form follows your income and eligibility, not simply the amount of tax payable. This is an overview; exclusions and the notified form for AY 2026–27 still need to be checked.

• ITR-1 is unavailable for NRIs/RNORs, business income, short-term capital gains, company directors and several other specified cases.
• Foreign income, overseas assets or signing authority, unlisted shares and losses require careful form review.
• Companies, LLPs, trusts and other entities may need ITR-5, ITR-6 or ITR-7; this table is not a guide for every entity.

New tax regime for AY 2026–27

The new regime is the default for eligible taxpayers. These slabs apply progressively to ordinary taxable income; income taxable at special rates needs a separate calculation.

• Eligible resident individuals may claim the Section 87A rebate, subject to its conditions. The rebate is not available to non-resident individuals.
• Add applicable surcharge and 4% Health and Education Cess on income tax plus surcharge.

Old regime or new regime: compare your actual position

A slab comparison alone is not enough. Review salary structure, standard deduction, HRA, home-loan interest, Section 80C investments, health-insurance premiums, NPS and other eligible deductions or exemptions. Which items are available depends on the regime and your circumstances.

The old regime can suit taxpayers with substantial eligible deductions; the new regime may suit those with fewer deductions. Compare both using complete income figures. For business or professional income, also check Form 10-IEA, the due date and restrictions on switching regimes.

Check AIS, TIS and Form 26AS against your records

AIS can include interest, dividends, securities and mutual-fund transactions, property information, tax credits and tax payments. TIS provides a summary of information categories. Use these with your own statements, rather than assuming that every prefilled figure is correct.

Form 26AS principally shows TDS and TCS information for this assessment year. Check advance tax and self-assessment tax against AIS and the payment challans or payment history. Review material differences with the deductor or reporting institution and use the AIS feedback facility where appropriate.

Do not omit taxable income merely because it is absent from AIS or Form 26AS. Keep the explanation and documents supporting each correction.

Capital gains need their own review

Shares, mutual funds, property, gold, bonds and other assets can require different holding-period and tax rules. Preserve purchase cost, acquisition and sale dates, sale value, improvement costs and transaction statements.

Check the correct short-term or long-term classification, any eligible exemption and the reporting schedule. A broker’s summary or bank receipt alone may not contain everything needed for the return.

Bring together your property-income records

Review property-income deductions and loss treatment under the chosen regime. A property sale requires a separate capital-gains review.

• Rent agreements, rent received and ownership shares for co-owned property.
• Municipal tax payments and home-loan interest certificates.
• Whether each property is self-occupied, let out or otherwise held.
• Purchase or sale documents and the related TDS and AIS entries.

Review business and professional income beyond the profit figure

Accurate books support an accurate return. Reconcile accounts, bank transactions and relevant GST data before finalising taxable income.

• Sales, receipts, expenses, TDS credits and tax-payment records.
• Stock, inventory, fixed assets and depreciation.
• Debtors, creditors, loans, advances and cash transactions.
• Presumptive-taxation eligibility, tax-audit applicability and advance-tax requirements.
• The profit and loss account, balance sheet and explanations for material differences.

Income Tax for NRIs

Review residential status for the year and the Indian income that remains taxable. Common items include rent, property and investment gains, bank interest, business or professional income and other Indian-source receipts.

The applicable DTAA, withholding and treaty-credit mechanism depend on the facts and country involved. Overseas foreign-tax-credit claims may require advice in that country. Living outside India does not automatically remove Indian filing obligations.

Common mistakes to avoid

• Choosing the wrong ITR form or tax regime.
• Ignoring interest income, capital gains, relevant bank accounts or required foreign disclosures.
• Claiming deductions without supporting documents.
• Failing to reconcile AIS, Form 26AS, tax payments and the underlying income.
• Filing a business return without resolving differences between books, bank records and GST data.
• Assuming a submitted return is complete before verification.

Official guidance: Annual Information Statement (AIS) · How to e-verify your return

Filing the return is only the first step

Complete verification within the applicable time limit and retain the acknowledgement. Then monitor processing, refund or demand status and any communication from the Department.

If something is wrong, identify whether the situation calls for a revised return, an eligible updated return, rectification or a response to a notice. Each route has its own conditions; they are not interchangeable.
