Income Tax Return Filing — Post-Registration Compliance Guide
Post-registration compliance in India is not merely a formality but a critical pillar of business integrity. For the fiscal year ending March 31, 2026, taxpayers must file their Income Tax Returns by July 31st to avoid late fees and interest charges under Section 234B or 234C. This guide outlines the mandatory timelines for individuals, HUFs, firms, LLPs, and companies, ensuring that your business remains audit-ready.
Before you start
- Obtain a valid Permanent Account Number (PAN) linked to Aadhaar before filing begins.
Step-by-step
Gather Financial Statements
Collect audited balance sheets, profit and loss accounts, and TDS certificates from Form 26AS. Ensure all digital signatures (DSC) or Aadhaar OTPs are active for electronic filing.
Select the Correct ITR Form
Individuals typically use ITR-1 up to ₹50 lakhs, while companies and LLPs must file via ITR-6. Firms often require ITR-4 or ITR-3 depending on their accounting method.
File Before the Due Date
Submit your return through the Income Tax e-Filing portal before July 31st, 2026. Late filing attracts a penalty of ₹50 per day up to a maximum limit.
Verify and Acknowledge Receipt
Check your email for the acknowledgement number (ITR-V). If filed physically or without DSC, verify via Form 13 within one month of filing.
Pay Advance Tax Shortfall
If you owe tax and have not paid enough advance tax by June 15th, file a challan immediately. Failure to pay results in interest under Section 234B at 1% per month.
Respond to Scrutiny Notices
If selected for scrutiny (Section 143(2)), respond within the stipulated time, usually three months from notice receipt. Provide supporting documents like Form 6B or 6C.
Maintain Digital Records
Store all ITR copies and correspondence in a secure digital folder for at least six years as per Section 287A of the Income Tax Act, which mandates record retention periods.
Common mistakes to avoid
- Failing to update bank account details before filing leads to bounced refunds.
- Ignoring TDS credits shown in Form 26AS results in underpayment and penalties.
- Not verifying the ITR-V form for physical submissions causes rejection of returns.
Frequently asked questions

Yes, you must still disclose assets and liabilities even with nil profit to avoid penalties for non-filing of returns under Section 139(4A).
What happens if the Income Tax Department rejects my return?
You will receive a notice detailing errors. You must rectify and re-file within thirty days or face scrutiny proceedings.
Is it mandatory to file ITR for salary income only?
