Check whether your business or freelance income crosses the tax audit threshold (₹1 crore for trading, ₹50 lakh for professional services) and engage a CA before 30 September 2026.
If you missed the July 31 ITR deadline, file your belated return before 31 December 2026 to avoid losing refund claims and the ability to carry forward capital loss deductions.

Here's what happened: The Income Tax Department has set multiple compliance deadlines between August and December 2026 for AY 2026-27, covering advance tax, TDS returns, audits, and belated ITR filing.. Advance tax must be paid in four instalments — 15 June, 15 September, 15 December, and 15 March — with the September and December instalments being the most critical for salaried taxpayers with additional income.. 31 December 2026 is the final deadline to file a belated or revised return for AY 2026-27; missing it permanently closes the window to claim refunds or correct errors for that assessment year..
What you should do: Calculate your total advance tax liability now — subtract TDS already deducted from your estimated annual tax and check whether you need to pay the September instalment by 15 September 2026.. Check whether your business or freelance income crosses the tax audit threshold (₹1 crore for trading, ₹50 lakh for professional services) and engage a CA before 30 September 2026.. If you missed the July 31 ITR deadline, file your belated return before 31 December 2026 to avoid losing refund claims and the ability to carry forward capital loss deductions..
Even salaried taxpayers earning rental or freelance income above ₹10,000 per quarter must pay advance tax — TDS from your employer salary alone does NOT exempt you from this obligation.
