1. Verify Your Personal Information
This may seem basic, but it's a common source of errors. Double-check that your PAN, Aadhaar number, name, date of birth, and address are all correctly entered. Most importantly, ensure the bank account you've listed for a potential refund is correct and has
been pre-validated on the e-filing portal. An incorrect account number or IFSC code is a primary reason for refund failures.
2. Reconcile Income with Form 26AS and AIS
This is the single most critical check. The Income Tax Department has a comprehensive record of your financial transactions in the Annual Information Statement (AIS) and a summary of taxes paid in Form 26AS. Before filing, download these documents from the e-filing portal. Cross-reference every source of income—salary, interest from bank deposits, mutual fund transactions, rental income, and dividends—with what is reported in your ITR draft. A mismatch between what you declare and what the department's records show is a primary trigger for automated notices.
3. Report All Sources of Income
Many taxpayers meticulously report their salary income but forget about smaller income streams. Interest earned from savings accounts and fixed deposits is taxable and must be reported. Similarly, don't forget to include income from house property, capital gains from selling stocks or property, or any freelance work. The AIS now captures most of these details, making it easy for the tax authorities to spot omissions. Even if some income is exempt from tax, it often needs to be declared in your return.
4. Choose the Correct ITR Form
Filing the wrong ITR form is like sending a letter in the wrong envelope—it will be returned. The department will issue a notice for a defective return under Section 139(9). For example, a salaried individual with no other income sources typically files ITR-1 (Sahaj). However, if you have capital gains from shares or mutual funds, you must file ITR-2. If you have income from a business or profession, you'll need ITR-3 or ITR-4. Carefully review the criteria for each form on the income tax portal to ensure you've selected the right one for your income profile.
5. Check Your Deductions and Tax Regime
Whether you have chosen the Old or New Tax Regime, a final review is essential. If you are using the Old Regime, ensure you have correctly claimed all eligible deductions under sections like 80C (for investments), 80D (for health insurance), and HRA. Do not claim deductions for which you don't have proof, as this can be flagged during scrutiny. If you've opted for the New Regime, confirm that you haven't claimed any deductions that are not permitted under it. A quick calculation check can prevent errors in your final tax liability.
6. Pay Self-Assessment Tax, if Any
After filling out all your details and calculating your final tax liability, the portal will show if you have any tax due. This is your 'self-assessment tax'. This amount must be paid in full before you can successfully file your return. Any delay or failure to pay this amount will result in your return being considered incomplete and will attract interest and penalties.
7. E-Verify Your Return After Submission
Filing your return is not complete the moment you hit 'submit'. The process is only finished once you e-verify it. You have a limited window (typically 30 days) to complete this step. Failure to e-verify renders your ITR invalid, meaning it's treated as if you never filed it at all. This can lead to a notice for non-filing and a late filing penalty. The easiest way to e-verify is through your Aadhaar OTP or your net banking portal.
