Here are 10 common ITR mistakes to avoid in 2025

• Using the wrong ITR form: Filing with the wrong form can cause delays or defect notices. For example, use ITR-1 only if your salary is below ₹50 lakh and you have no capital gains.
• Not verifying the ITR: If you don’t e-verify your return after filing, it will be treated as not submitted. Verification is mandatory.
• Wrong assessment year: For income earned in 2024–25, select AY 2025–26. Choosing the wrong year can lead to fines.
• Incorrect personal details: Mistakes in your name, PAN, date of birth, bank account, or contact details can cause problems with processing and refunds.
• Missing other income: Declare all income sources, including interest on savings or fixed deposits, rental income, or capital gains. Omissions can attract notices and fines.
• Wrong format: Fill in details exactly as required in the ITR form. Incorrect formats can lead to errors in your return.
• Wrong tax regime: Choosing the wrong tax regime could mean missing out on benefits or deductions. Choose the one best suited to your income.
• Missing exemption claims: If you reinvest capital gains, don’t forget to claim exemptions under sections like 54, 54EC, or 54F.
• Ignoring notices: If the tax department sends you a notice, respond promptly. Ignoring it can lead to penalties or legal action.
• Not paying advance tax: Pay your tax on time. Late or short payments attract 1% interest per month on the unpaid amount.
