Overview
FY 2026-27 runs from 1 April 2026 to 31 March 2027. The corresponding Assessment Year is AY 2027-28 — this is the year in which the Income Tax Department assesses your income earned during FY 2026-27 and you file your return.
1 Apr 2026 — 31 Mar 2027
Assessment year for this FY
15 Jun, 15 Sep, 15 Dec, 15 Mar
Key compliance milestones you need to track: 4 advance tax installments (if your tax liability exceeds the threshold), ITR filing deadlines (varying by case type), revised return window (31 December of the assessment year), and the updated return window (24 months from end of AY under Section 139(8A)).
WHY THESE DATES MATTER
Missing any of these dates can cost you penalties and interest. Late ITR filing attracts a penalty up to ₹5,000 under Section 234F. Missed advance tax installments attract interest under Sections 234B and 234C. Mark these dates — the department does not send reminders.
