Taxpayers in India face a busy end to 2026 with key filing, payment and reporting deadlines, as the transition to the new Income-tax Act framework introduces new requirements and considerations for the assessment year 2026-27.
India’s tax calendar remains busy through the end of 2026, with a series of filing, payment and reporting deadlines that taxpayers need to keep on their radar after the July return deadline has passed. According to Zee Business, the key dates run from 31 August through 31 December and cover income-tax returns, advance tax, tax audit reports, TDS statements and belated returns.
The first major checkpoint is 31 August 2026, when eligible taxpayers whose accounts do not need an audit must file their income-tax return for assessment year 2026-27, which relates to income earned in financial year 2025-26. India Briefing also flags August as an important compliance month for non-audit business taxpayers, particularly those filing ITR-3 or ITR-4. Taxpayers in this group should make sure their income, tax deducted at source and deductions are properly reconciled before filing.
The next deadline is 15 September 2026, the due date for the second instalment of advance tax for those liable to pay it. Zee Business says taxpayers should have paid 45% of their estimated annual tax by then, after earlier instalments are taken into account. This matters most for people whose tax bill is not fully covered by TDS, including those with business, professional, rental, interest or capital gains income.
For taxpayers subject to audit, 30 September 2026 is the deadline to submit the tax audit report for assessment year 2026-27. The return itself is then due by 31 October 2026, except in transfer-pricing cases, where the filing deadline is later. On the same day, applicable deductors must also file the quarterly TDS statement for the July-to-September period, making 31 October a dense compliance date for employers and businesses.
Those covered by transfer-pricing rules have until 30 November 2026 to file their return, while the third advance-tax instalment falls due on 15 December 2026, by which point taxpayers generally should have paid 75% of their estimated yearly liability. The final date in the 2026 calendar is 31 December 2026, when taxpayers who missed the original deadline can still file a belated return for assessment year 2026-27, subject to the applicable rules.
Zee Business also notes that 2026 is a transitional year because of the shift to the Income-tax Act, 2025 framework. Assessment year 2026-27 continues to relate to income earned in FY 2025-26 under the earlier law, while tax year 2026-27 covers income earned during FY 2026-27. For return filing, taxpayers choosing the old regime should also keep an eye on deductions such as Section 80C, which remains available only for eligible filers under the old system and is subject to the usual limits and conditions.
