Filing your Income Tax Return (ITR) online in India is straightforward, mandatory for most taxpayers, and essential to claim refunds, carry forward losses, or avoid penalties. For Assessment Year (AY) 2026-27 (corresponding to Financial Year/FY 2025-26), the due date for non-audit cases is typically 31 July 2026 (confirm on incometax.gov.in for extensions). The process uses the official e-Filing portal (incometax.gov.in), with pre-filled data from Form 16, AIS (Annual Information Statement), and TIS (Tax Information Summary) making it easier.

This 2026 guide provides a step-by-step process for online filing (preferred mode), based on the latest Income Tax Department user manuals for ITR-1 (Sahaj), ITR-2, and general instructions (as of January 2026). Most salaried individuals use ITR-1 or ITR-2; choose the correct form based on your income sources.

Key Updates for AY 2026-27:

• Pre-filled returns with AIS/TIS data (salaries, interest, TDS, capital gains).
• Mandatory Aadhaar-PAN linkage (if not linked, PAN may be inoperative).
• Updated timelines for updated returns (up to 48 months from AY 2026-27).
• No Java/Excel utilities for some; focus on online mode or new offline JSON uploads.
• Faceless processing and improved e-verification options (Aadhaar OTP, net banking, Demat).

Documents Required:

• PAN & Aadhaar.
• Form 16/16A (TDS from salary/others).
• Bank statements, interest certificates.
• Investment proofs (80C, 80D, etc.).
• Capital gains statements (if applicable).
• Previous ITR acknowledgment (for carry forward).
