India's Tax Season: Key ITR and TDS Deadlines for AY 2026-27 Unveiled

As India enters the new tax season, taxpayers are gearing up for the Assessment Year (AY) 2026-27, which pertains to income earned during Financial Year (FY) 225-26. This period introduces a revamped set of deadlines and compliance requirements, underscoring the importance of meticulous planning and adherence to avoid penalties and ensure accurate tax filing. It is crucial to note that while the Income Tax Act, 2025, and Income Tax Rules, 2026, come into effect from Tax Year (TY) 2026-27 (FY 2026-27) onwards, the filing for AY 2026-27 (FY 2025-26) remains governed by the Income Tax Act, 1961, and its corresponding rules.

Income Tax Return (ITR) Filing Deadlines for AY 2026-27

The Union Budget 2026-27 introduced significant changes to ITR deadlines, moving away from a uniform approach to a tiered system based on the applicable ITR form and taxpayer category. This aims to alleviate peak-period congestion on e-filing portals.

• July 31, 2026: This is the primary deadline for most individual taxpayers, including salaried employees, pensioners, and presumptive taxpayers filing ITR-1 or ITR-4. It also applies to those with income from one house property, fixed deposits, savings accounts, or capital gains without business income.
• August 31, 2026: Individuals with business income not subject to tax audit, filing ITR-3 or ITR-4, have until this date.
• October 31, 2026: Businesses and professionals requiring a tax audit, including companies and LLPs, must file by this date. The tax audit report itself is due one month prior, typically by September 30, 2026.
• November 30, 2026: A specific extension is provided for cases involving transfer pricing reports, particularly those with international or specified domestic transactions. The Form 3CEB (transfer pricing audit report) is due by October 31, 2026.

Consequences of Delayed ITR Filing

Missing these stipulated deadlines can lead to several financial repercussions:

• Late Filing Fee: Under Section 234F, a penalty of ₹1,000 is levied if the total income does not exceed ₹5,00,000, while a fee of ₹5,000 applies in all other cases.
• Interest on Unpaid Taxes: Interest will be charged on any unpaid tax amount.
• Loss of Carry-Forward Benefits: Taxpayers lose the ability to carry forward certain losses to future assessment years if the return is not filed by the original due date.
• Belated and Revised Returns: A belated return for AY 2026-27 can be filed by December 31, 2026, subject to late fees. Furthermore, Budget 2026 extended the revised return deadline to March 31, 2027, allowing taxpayers to correct errors or omissions in their original filing.

The Indispensable Role of Form 26AS

Before filing an ITR, verifying Form 26AS is more crucial than ever due to enhanced data matching by tax authorities. Form 26AS is a consolidated tax statement linked to a taxpayer's Permanent Account Number (PAN), acting as a 'tax passbook' that records details of Tax Deducted at Source (TDS), Tax Collected at Source (TCS), advance tax payments, self-assessment tax, refunds, and specified high-value financial transactions.

Key benefits of reviewing Form 26AS:

• Verifies Tax Credits: It helps taxpayers confirm that all TDS, TCS, and other taxes have been correctly deposited against their PAN. Only TDS reflected in Form 26AS can generally be claimed.
• Ensures Accurate ITR Filing: Cross-checking details helps in accurate return filing, preventing errors and reducing the likelihood of receiving tax notices.
• Identifies Discrepancies: It assists in detecting issues like incorrect PAN details, missing TDS entries, or reporting errors, allowing for timely corrections.
• Reconciliation with AIS and TIS: Taxpayers should meticulously reconcile Form 26AS with the Annual Information Statement (AIS) and Taxpayer Information Summary (TIS), along with personal records like salary slips and bank statements, to ensure complete and accurate income reporting. From Tax Year 2026-27, Form 26AS is set to be replaced by Form 168, which will integrate AIS data into a single, unified statement.

New ITR Rules and Exempt Income Reporting for AY 2026-27

For AY 2026-27, ITR forms have been updated with specific fields for reporting exempt incomes, aiming to enhance compliance and reduce reliance on manual disclosures. Taxpayers must ensure that all exempt income is reported to avoid discrepancies with the Income Tax Department's data and potential compliance queries.

Noteworthy changes also include:

• Expanded ITR-1 and ITR-4 Eligibility: These simplified forms can now be used by taxpayers having income from up to two house properties, a relaxation from the previous one-property limit.
• Standardized Exempt Allowances: The 'Others' category for claiming exempt allowances in ITR-1 and ITR-2 has been removed, meaning exemptions can now only be claimed for allowances specifically listed in the forms.
• Enhanced Contact Information: ITR-1, ITR-2, and ITR-4 now require additional communication details such as a secondary mobile number, email address, and address to ensure uninterrupted contact with the tax department.
• ITR-4 Disclosures: Taxpayers opting for presumptive taxation under ITR-4 face increased disclosure requirements, including mandatory reporting of bank balances.
• New Tax Regime Updates: The New Tax Regime, now the default, features revised tax slabs for AY 2026-27 with income up to ₹4 lakh being exempt and progressive rates applying thereafter. A standard deduction of ₹75,000 for salaried individuals under this regime can make income up to ₹12.75 lakh effectively tax-free. Taxpayers can still opt for the old regime, considering its wider range of deductions and exemptions, particularly with higher exemption limits on allowances introduced by the Income Tax Rules 2026 for FY 2026-27 onwards.

TDS Compliance for Financial Year 2026-27

For FY 2026-27, a robust framework for Tax Deducted at Source (TDS) compliance is in place, with strict adherence required for both payments and return filings. Deductors must be vigilant to avoid penalties and interest charges.

TDS Payment Due Dates:

• Generally, TDS must be deposited by the 7th of the month following the deduction.
• An exception exists for TDS deducted in March, which can be deposited by April 30, 2027.
• Government deductors making payments through book entry must deposit TDS on the same day of deduction, with March deductions due by April 7.

TDS Return Filing Due Dates (Quarterly):

• Q1 (April-June 2026): July 31, 2026
• Q2 (July-September 2026): October 31, 2026
• Q3 (October-December 2026): January 31, 2027
• Q4 (January-March 2027): May 31, 2027

Applicable Forms:

Deductors use specific forms based on the nature of payment: Form 24Q for salaries, Form 26Q for non-salary payments, and Form 27Q for payments to non-residents.

Penalties and Interest for Non-Compliance:

• Late Filing Fee (Section 234E): A daily fine of ₹200 applies for delayed quarterly statements, capped at the total deducted amount for that return.
• Late Payment Interest: Interest of 1% per month is charged if tax was not deducted on time, and 1.5% per month if tax was deducted but not deposited on time.
• Non-Filing Penalties (Section 271H): If returns remain unfiled for more than a year from the original due date, penalties ranging from ₹10,000 to ₹1,00,000 may be levied.

Key Compliance Updates for TDS:

Compliance has been strengthened with increased automation, real-time AIS reporting, robust PAN validation, and automated mismatch detection. Deductors must ensure accurate Challan Identification Numbers (CIN) and tax amounts match perfectly on the Income Tax Department Portal. Furthermore, TDS certificates (Form 130/Old Form 16 for salaries by June 15, and Form 131/Old Form 16A for non-salary within 15 days of filing the quarterly return) must be issued to deductees promptly.

Staying informed about these critical dates and changes is paramount for all Indian taxpayers to ensure a smooth and compliant tax filing experience for AY 2026-27.
