Income Tax Audit 2025: Key Deadlines, Rules, and Penalties Explained

As the financial year 2024–25 draws to a close, taxpayers subject to audit must gear up for critical compliance deadlines. The Income Tax Audit Report is a mandatory filing for certain businesses and professionals under Section 44AB of the Income Tax Act, and missing it can lead to steep penalties.

Key Deadlines

Tax Audit Report Submission: September 30, 2025

Income Tax Return (ITR) Filing (for audited entities): October 31, 2025

These dates apply to companies, proprietorships, and professionals whose income exceeds prescribed thresholds. The audit report must be filed before the ITR to avoid complications.
