Income Tax Filing India 2025: Complete AY 2025-26 Guide

Income tax filing India 2025 usually refers to filing an income-tax return during calendar year 2025 for income earned in Financial Year 2024-25, which is Assessment Year 2025-26. The distinction matters because the e-Filing portal asks for the assessment year, not simply the calendar year in which you log in. A taxpayer should first identify the income period, then choose the correct assessment year, taxpayer status and return form. For a typical salaried individual filing income earned from 1 April 2024 to 31 March 2025, the correct assessment year is 2025-26. Before submission, reconcile Form 16, bank interest, capital gains, TDS, advance tax, self-assessment tax, AIS and Form 26AS. The return is complete only after successful verification. Because the original and belated filing windows for AY 2025-26 have now passed, a person dealing with this year in 2026 should check whether an updated return route is legally available and suitable rather than attempting a normal belated return.

Select Assessment Year 2025-26 for income earned between 1 April 2024 and 31 March 2025. Financial year is the period in which income is earned; assessment year is the following year in which that income is assessed and the return is filed. Selecting AY 2024-25 would normally relate to income earned in FY 2023-24, while AY 2026-27 relates to FY 2025-26. This is one of the most consequential dropdown choices on the portal because tax rates, return utilities, validation rules and filing time limits are year-specific. Check the year printed on Form 16, Form 16A, broker statements and tax challans. If a payment was made under the wrong assessment year, do not simply claim it in another year without checking the correction process and tax records. Where multiple years are pending, prepare a separate reconciliation for each assessment year and obtain expert review before filing.

A salaried person should normally collect Form 16 from every employer, salary slips where reconciliation is needed, Form 26AS, AIS and TIS, bank interest certificates, home-loan interest certificate, rent and HRA records where relevant, evidence for eligible deductions, capital-gains statements, dividend records, details of other income and tax-payment challans. Also keep PAN, Aadhaar-linked contact access, bank account details and the previous return for comparison. Do not treat Form 16 as the entire return: AIS may show interest, securities transactions, dividends, property transactions or other information not captured by the employer. Compare figures rather than copying blindly. If an item in AIS is incorrect, submit feedback where appropriate, but disclose taxable income based on the law and your records. A clean document pack reduces mismatches, interest, notices and refund delays. WealthSure's assisted filing service can be useful where there are two employers, capital gains, foreign assets, arrears, house-property complications or material AIS differences.

Choose the ITR form according to residential status, total income, income sources, ownership interests and other statutory conditions—not merely because a form looks simpler. ITR-1 is intended only for eligible resident individuals within its scope, while taxpayers with capital gains, foreign assets, multiple house-property situations, business or professional income, partnership interests or other exclusions may need another form. The portal provides a form-selection aid, but the answers must be accurate. Review the official applicability notes for AY 2025-26 before filing. A wrong form can make a return defective or incomplete even when the tax calculation appears correct. Pay special attention if you traded shares or derivatives, sold property, received freelance income, were a director, held unlisted shares, had foreign income or qualified as not ordinarily resident or non-resident. In uncertain cases, form selection is a strong reason to use professional review before submission.

As of 5 August 2026, the ordinary belated and revised-return windows for AY 2025-26 have expired. The Income Tax Department has stated that revised or belated returns for AY 2025-26 or earlier cannot be filed on or after 1 April 2026. Depending on the facts, an updated return under the applicable law may still be available, subject to eligibility, time limits, additional tax and restrictions. An updated return is not a universal substitute: it generally cannot be used to reduce tax liability, claim or increase a refund, or in situations barred by law. Before proceeding, compute all income, taxes and interest, examine whether an updated return is permissible, and verify that the selected utility is for AY 2025-26. A taxpayer who missed filing should avoid entering figures experimentally on the portal because the legal route and cost can differ materially. Expert support is particularly useful where tax is payable, losses were involved, a refund was expected or a notice has already been received.

Form 26AS is a tax-credit statement that primarily reflects items such as TDS, TCS, certain tax payments and specified information. AIS is broader and can include interest, dividends, securities transactions, property-related information, foreign remittances and other reported data. TIS presents processed or derived values from AIS for taxpayer information and return prefill. None should be read in isolation. Compare them with Form 16, Form 16A, bank statements, broker reports, sale documents and your books. A transaction appearing in AIS is not automatically the final taxable figure, and an omission from AIS does not make taxable income non-taxable. Use the feedback facility for inaccurate information where appropriate, but file based on complete facts and applicable law. Preserve the reconciliation because it explains why the return figure may differ from an information statement and can help if the department later seeks clarification.

First complete the income and tax computation for AY 2025-26, give credit for eligible TDS, TCS and advance tax, and calculate interest and fee where applicable. If tax remains payable, use the official e-Pay Tax service on the Income Tax e-Filing portal, select the correct PAN, assessment year and payment category, and review the amount allocation before authorising payment. Save the challan receipt and CIN or payment reference. Return to the filing workflow and confirm that the payment is reflected or enter the challan details correctly where required. Do not select the year based only on the payment date. A payment made in 2026 may still relate to AY 2025-26. If money is debited but a challan is not generated, check payment history and bank status before paying again. Duplicate payment can create avoidable correction or refund work. Keep the final payment proof with the filed return and computation.

E-verification completes the filing process. Uploading or submitting return data without verification leaves the return pending and can cause it to be treated as not validly filed if verification is not completed within the prescribed time. Common methods include Aadhaar OTP, net banking, bank-account EVC, demat-account EVC or other portal-supported options. After verification, download the acknowledgement and check the return status on the portal. Do not rely only on a screen saying that data was submitted. Confirm that the status shows successfully verified or processed as applicable. Keep access to the mobile number and bank or demat account needed for the chosen method. If electronic verification is unavailable, follow the portal's permitted ITR-V process and timeline. For an old assessment year or updated return, check the current portal instructions because timelines and available methods may change.

Refunds may be delayed by an unverified return, incorrect bank details, a bank account that is not validated or nominated, mismatch between claimed TDS and Form 26AS, incomplete income disclosure, incorrect assessment year, return defects, outstanding demands or additional verification by the department. A refund amount shown in the return is only a claim until processed; it is not guaranteed. Before filing, reconcile tax credits and income statements, validate the bank account, use the correct ITR form and review the computation. After filing, e-verify promptly and monitor return status, notices and refund messages through official channels. If the department issues an intimation that differs from the return, compare each adjustment rather than assuming it is wrong. Where a credit is missing, trace the deductor's filing and correction status. WealthSure can help review mismatches and response options, but the final refund remains subject to Income Tax Department processing.

Expert-assisted filing is worth considering when the return involves more than straightforward salary and bank interest, when records do not reconcile, or when the consequences of an error are meaningful. Examples include capital gains, derivatives, crypto reporting, freelance or professional receipts, multiple employers, house-property loss, foreign income or assets, NRI status, ESOPs, unlisted shares, business books, prior-year omissions, an updated return, a tax notice or a material AIS mismatch. Assistance can also be sensible for a first-time filer who is unsure about the assessment year, form or tax regime. A competent review should explain assumptions, ask for supporting records, reconcile tax credits and provide the computation and acknowledgement. It should not promise a guaranteed refund or invent deductions. WealthSure's assisted ITR filing and tax-expert services are intended for users who want support with form selection, document matching, tax payment, verification and post-filing records.
