Common Mistakes to Avoid While Filing ITR
Common Misconception: "If My Income is Up to ₹12 Lakh, I Don't Need to File an ITR"
This is one of the most widely misunderstood aspects of the new tax regime. The fact that an individual may not ultimately pay any income tax due to the rebate provisions does not automatically mean that filing an Income Tax Return is unnecessary.
Basic Exemption Limit for Mandatory ITR Filing
Generally, an individual is required to file an Income Tax Return if their gross total income before claiming deductions and exemptions exceeds the applicable basic exemption limit. The basic exemption limits are:
- Old Tax Regime: ₹2.5 lakh for individuals below 60 years of age.
- New Tax Regime: ₹4 lakh.
However, even if your income is below these limits, filing an ITR may still be mandatory in certain cases or beneficial for claiming refunds and maintaining financial records. You may still be required or strongly advised to file an ITR because:
- TDS may have been deducted and a refund needs to be claimed.
- You have capital gains from shares, mutual funds or property transactions.
- You hold foreign assets or have foreign income.
- You wish to carry forward capital losses to future years.
- You need ITRs for loan applications, visa applications or financial documentation.
Certain specified transactions, such as high-value deposits, foreign travel expenditure, or substantial electricity consumption, may trigger mandatory filing requirements even if no tax is ultimately payable.
