New Income Tax Slabs & ITR Due Dates For FY 2025-26 (AY 2026-27): Full List of Deadlines, Extensions and Tax Rates & Penalities | Explained

NEW DELHI: The Income Tax Act prescribes various penalties and prosecutions for non-compliance, ranging from late filing of returns to willful tax evasion.

Understanding penalties and prosecutions under the Income Tax Act is crucial for taxpayers in India. Non-compliance can attract monetary fines, penalties, or even imprisonment. This guide provides a consolidated overview of various penalties and prosecutions applicable for Assessment Year (AY) 2026-27.

ITR Filing Due Dates AY 2025-26 (FY 2024-25)

  • Individuals/HUFs/AOPs/BOIs (no audit): September 15, 2025
  • Businesses & professionals (audit required): October 31, 2025
  • Transfer Pricing audit (Form 3CEB): November 30, 2025
  • Belated return (with penalty): December 31, 2025

Penalties for missing September 15 deadline:

  • Income ≤ Rs 5 lakh → Rs 1,000
  • Income > Rs 5 lakh → Rs 5,000 (u/s 234F)
  • An additional 1% monthly interest (u/s 234A) on unpaid tax.
  • Losses cannot be carried forward.

Extension chances: Low, as over 4 crore ITRs have already been filed by September 1, 2025, and the government expects filings to cross 7 crore before the deadline.

The Union Budget 2025 introduced major relaxations under the new tax regime, reducing tax liability for most taxpayers.

  • New Regime Highlights:
    • Basic exemption limit raised to Rs 4 lakh (from Rs 3 lakh).
    • Income up to Rs 12 lakh is tax-free due to an enhanced rebate of Rs 60,000.
    • 30% tax rate now applies only above Rs 24 lakh (earlier Rs 15 lakh).
    • Standard deduction of Rs 75,000 available.
    • Limited deductions allowed, but NPS contribution and home loan interest on let-out property remain.
  • Old Regime:
    • Slabs unchanged.
    • More deductions/exemptions available (80C, 80D, HRA, LTA, etc.).
    • Senior and super senior citizens continue to enjoy higher exemption limits.
  • Other Changes:
    • TDS thresholds relaxed.
    • Surcharge capped at 25% under new regime (vs. 37% in old).
    • Rebate not applicable to special income (capital gains, crypto, gaming).
  • Which is Better?
    • New regime: Beneficial for middle-income earners and those with fewer deductions.
    • Old regime: Beneficial if deductions exceed break-even limits (around Rs 4.5–8 lakh depending on income).

Bottom Line:
For FY 2025-26, most middle-class taxpayers benefit from the new regime, while high-income earners with large deductions may still prefer the old regime.
