Filing your Income Tax Return (ITR) is one of the most important financial responsibilities for every taxpayer. While the process has become easier with online filing, many people still make small mistakes that can delay refunds or lead to notices from the Income Tax Department.
To help taxpayers file their returns correctly, the Income Tax Department has highlighted several important guidelines for the 2026 filing season. Following these simple steps can make the filing process smoother and help avoid unnecessary problems later.

1. Choose the Right Tax Regime
One of the first decisions while filing your ITR is selecting the appropriate tax regime. Taxpayers can choose between the Old Tax Regime and the New Tax Regime, depending on which offers better tax benefits based on their income and eligible deductions.
Before submitting your return, compare both options carefully to determine which one helps you save more tax.
2. Keep All Important Documents Ready
Before starting the filing process, make sure you have all the necessary documents, including:
- PAN Card
- Aadhaar Card
- Form 16 (if applicable)
- Bank account details
- Interest income statements
- Investment and deduction proofs
- Capital gains details (if any)
Having these documents ready helps reduce errors while filing.
3. Verify Your Income Details Carefully
Always cross-check the income details shown in your tax records with your salary slips, bank statements, and investment income.
Ensure that salary income, interest earnings, rental income, business income, and capital gains are correctly reported before submitting the return.
4. Claim Deductions Only If Eligible
If you choose the Old Tax Regime, make sure you claim deductions only when you are eligible. Incorrect deduction claims may lead to additional scrutiny or notices from the Income Tax Department.
Double-check all supporting documents before claiming tax benefits.
5. Check Your Bank Account Information
Providing the correct bank account details is important because income tax refunds are credited directly to the registered account.
Verify the account number, IFSC code, and ensure your bank account is pre-validated on the income tax portal.
6. Complete the E-Verification Process
Many taxpayers believe filing the return is the final step, but e-verification is equally important.
After submitting the ITR, complete the e-verification process using Aadhaar OTP, net banking, digital signature, or other available methods. An unverified return is treated as incomplete and may not be processed.
7. Review Everything Before Final Submission
Before clicking the final submit button, review every section of your return carefully.
Check:
- Personal information
- PAN and Aadhaar details
- Income figures
- Tax calculations
- Deductions claimed
- Bank account details
Taking a few extra minutes to review your return can help prevent mistakes and delays.
Common Mistakes to Avoid
Many taxpayers make avoidable errors while filing their returns. Some common mistakes include:
- Selecting the wrong ITR form
- Entering incorrect bank account details
- Forgetting to report all income sources
- Claiming ineligible deductions
- Missing the e-verification step
- Filing after the due date
Avoiding these mistakes can make the filing process much smoother.
