Introduction
Timely filing of the income tax return is one of the most important compliance steps for every taxpayer. Missing the due date can lead to interest, late fees, and restricted loss carry-forward, and unnecessary notices. For that reason, taxpayers should keep track of the latest due dates applicable for A.Y. 2026-27 instead of relying on older extension-based calendars from prior years.
The current filing season relates to F.Y. 2025-26 and A.Y. 2026-27. Different categories of taxpayers have different due dates depending on whether their accounts are subject to audit, whether they are covered by transfer pricing provisions, and which ITR form they are required to file.

Important filing updates this year
A.Y. 2026-27 brings a few practical changes that taxpayers should keep in mind while preparing their returns. One important update is that ITR-1 and ITR-4 now allow reporting of up to two house properties, subject to the other eligibility conditions of those forms.
Another important change is the introduction of reporting fields for unrealized rent in the updated filing framework. These changes may simplify reporting for some taxpayers, but they also make it important to choose the correct ITR form based on the actual nature of income.
Why filing on time matters:
Filing the return on or before the due date is not just about avoiding penalties. A timely return helps the taxpayer carry forward eligible losses, claim refunds faster, maintain a clean compliance profile, and avoid unnecessary notices from the department. Delay in filing may also affect financial documentation required for loans, visas, tenders, and other business or personal purposes.
For salaried individuals, early filing is usually easier because Form 16, AIS, TIS, and other annual documents become available in time. For business taxpayers, the return should ideally be planned well before the deadline so that books, reconciliations, TDS credits, and audit requirements are completed smoothly.
Final note
Taxpayers should always verify the applicable due date based on their category before filing. A non-audit salaried person, a business owner requiring an audit, and a taxpayer having international or specified domestic transactions can all have different deadlines. Using the correct due date and the correct ITR form is the first step toward smooth and penalty-free compliance.
