Tax season 2026 brings significant changes to India's income tax filing process with updated due dates from the Central Board of Direct Taxes (CBDT). Salaried individuals, pensioners, and investors filing ITR-1 or ITR-2 have until 31 July 2026 to submit their returns, while businesses and professionals filing ITR-3 or ITR-4 now have until 31 August 2026 due to the extended deadline. The filing window opened on 30 March 2026 when the Income Tax Department released all ITR forms (ITR-1 to ITR-7). As reported, missing the original deadline can result in late filing fees of ₹1,000 for income up to ₹5 lakh or ₹5,000 for higher incomes, along with interest charges of 1% per month on unpaid taxes. The extension of due dates for ITR-3 and ITR-4 represents one of the major changes introduced for FY 2025-26, providing additional relief to professionals, freelancers, consultants, and small businesses.
The guide explains the fundamental choice between two tax regimes that significantly impacts tax liability. Under the new tax regime, individuals earning up to ₹12 lakh can benefit from the enhanced Section 87A rebate of up to ₹60,000, making their effective tax-free salary up to ₹12.75 lakh after adding the standard deduction of ₹75,000. The new regime offers lower slab rates but eliminates popular deductions like Section 80C, 80D, HRA, and home loan interest under Section 24(b). In contrast, the old tax regime maintains all deductions but charges higher rates, with a smaller rebate of up to ₹12,500 covering taxable income up to ₹5 lakh. The choice depends on the number of deductions claimed, with the old regime favoring those with genuine investments in rent, home loans, insurance, and Section 80C instruments. Budget 2025 has introduced significant changes to the new tax regime, including restructured income tax slabs where income up to ₹4 lakh is exempt and progressive rates ranging from 5% to 30% apply thereafter, providing greater relief to middle-income taxpayers.
The Income Tax Department has released all ITR forms with specific guidelines for each category. ITR-1 (Sahaj) is for resident individuals with total income up to ₹50 lakh from salary or pension, one or more house properties, and other sources. A major change this year allows reporting income from up to two house properties in ITR-1, eliminating the need to file ITR-2 for multiple property owners. ITR-2 is for individuals with capital gains, more than two house properties, foreign income, or total income above ₹50 lakh but no business income. ITR-3 is for individuals and HUFs earning business or professional income requiring book-keeping, while ITR-4 (Sugam) serves small businesses and professionals under presumptive taxation schemes. As reported, choosing the wrong form can result in return rejection and the need for correction and re-submission. The key distinction between ITR-1 and ITR-2 comes down to whether you sold any investments or earned above ₹50 lakh - if yes, ITR-2 is mandatory.
According to the comprehensive guide, proper documentation preparation is crucial for smooth filing. Essential documents include PAN and Aadhaar with mandatory linking, Form 16 for salaried employees containing salary and TDS details, Form 26AS and AIS/TIS showing income and taxes recorded by the Income Tax Department, and bank account details with interest certificates for taxable savings and fixed deposit income. For capital gains, taxpayers must collect statements from brokers or investment platforms for shares, mutual funds, property, or other investments sold during the year. The revised ITR forms for AY 2026-27 reflect significant changes in reporting requirements, with enhanced disclosures for rental income, donations, political contributions, interest income, and tax regime choices. Taxpayers must now provide tenant-related details including PAN or Aadhaar for Section 194-IB deductions and TAN for Section 194-I deductions, while retirement benefit accounts maintained outside India are no longer required to be reported in ITR-1 and ITR-4. The guide emphasizes that having these documents ready beforehand helps avoid last-minute hassles and ensures accurate filing, with increased disclosures and updated reporting requirements making early preparation essential for taxpayers.
The guide provides a detailed step-by-step process for online ITR filing through the Income Tax e-filing portal, with the Income Tax Department enabling Excel utilities for ITR-1 and ITR-4 on the official portal to facilitate easier data entry. Taxpayers must log in using PAN as user ID and password, then select Assessment Year 2026-27 and choose the correct ITR form based on their taxpayer category. The portal automatically imports pre-filled information such as salary, TDS, and interest income, which must be reviewed carefully against Form 16, Form 26AS, and AIS for accuracy. Taxpayers can select their preferred tax regime - the new regime being the default - and add remaining income and eligible deductions before the system calculates tax liability. E-verification within 30 days is mandatory, which can be completed instantly through Aadhaar OTP, net banking, electronic verification code (EVC), or digital signature certificate (DSC). The guide emphasizes that online verification is quicker and recommended over sending the ITR-V form by post, and that taxpayers should avoid waiting until the last week of filing season to ensure timely compliance. Budget 2025 has extended the deadline for filing revised returns from 31 December to 31 March of the relevant assessment year, though a new fee of ₹1,000 for income up to ₹5 lakh and ₹5,000 for higher incomes applies for returns filed during this extended period.
