Essential Personal Information
Before you even begin, ensure your core details are correct and accessible. This includes your PAN card, which is mandatory for filing. Crucially, your PAN must be linked with your Aadhaar card; otherwise, your return could be considered invalid. Also,
keep your current mobile number and email address handy, as these are needed for OTP-based verification processes on the e-filing portal. Finally, have the account numbers and IFSC codes for all your active bank accounts ready, as you must report them. Ensure the primary account where you wish to receive any potential refund is pre-validated on the income tax portal to avoid delays.
Gather Your Income Proofs
For salaried individuals, Form 16 is the most critical document. It is a TDS certificate from your employer detailing your salary, allowances, and the tax deducted. If you switched jobs during the financial year, you will need to collect Form 16 from all your employers. Beyond salary, gather proof for all other income sources. This includes interest certificates from banks and post offices for your savings accounts and fixed deposits, rental agreements and municipal tax receipts for any property you've leased out, and statements detailing dividend income from stocks and mutual funds.
Verify with Form 26AS and AIS
Do not file your return without cross-referencing Form 26AS and the Annual Information Statement (AIS). Form 26AS is your tax passbook, showing all taxes deducted at source (TDS), tax collected at source (TCS), and advance taxes paid against your PAN. The AIS is even more comprehensive, providing a detailed summary of your financial transactions, including interest, dividends, securities transactions, and more, as reported to the tax department by various financial entities. Reconciling your income details with these two forms is vital to prevent any mismatch that could trigger a notice from the tax department.
Documents for Deductions
If you are using the old tax regime, collecting proof of your tax-saving investments and expenses is essential to lower your taxable income. This includes receipts for life insurance (LIC) premiums, contributions to Public Provident Fund (PPF), and statements for Equity Linked Savings Scheme (ELSS) investments, all of which fall under Section 80C. Keep health insurance premium receipts for Section 80D deductions. If you have a home loan, the loan statement showing the principal and interest paid is necessary to claim deductions. Also, gather donation receipts for Section 80G claims and tuition fee receipts for your children's education.
Capital Gains Statements
If you have sold property, stocks, or mutual funds during the financial year, you must report the capital gains. For this, you will need detailed statements from your stockbroker that summarise your profit and loss. For mutual funds, you can get consolidated statements from registrar and transfer agents like CAMS or KFintech. In case of property sale, you will need the purchase and sale deeds, along with proof of any expenses incurred on transfer or improvement of the property. Having these documents helps in accurately calculating short-term or long-term capital gains and the corresponding tax.
Final Pre-Filing Steps
Once you have all your documents, take a moment for a final check. First, choose the correct ITR form (e.g., ITR-1 for salaried individuals with income up to ₹50 lakh and one house property, ITR-2 for those with capital gains). Selecting the wrong form is a common error that can lead to your return being marked as defective. Also, ensure you are filing for the correct Assessment Year, which is AY 2026-27 for income earned in the Financial Year 2025-26. After filing, you must e-verify your return within 30 days using options like Aadhaar OTP or net banking for the process to be complete.
