Income tax compliance in India comes with strict timelines and accuracy requirements. Small oversights or deliberate errors can result in substantial penalties that significantly increase your tax liability. Being aware of these common mistakes can help you avoid costly consequences.
Missing the Income Tax Return Filing Deadline
One of the most common mistakes is missing the deadline to file your Income Tax Return (ITR). For individuals not requiring audit, the deadline is typically July 31st of the assessment year. Missing this date triggers a late filing fee under Section 234F.
If your total income exceeds Rs 5 lakh, the penalty is Rs 5,000. For those with income up to Rs 5 lakh, the fee is Rs 1,000. However, if you fail to file even the belated return by December 31st of the assessment year, you lose the opportunity to file altogether for that year, and may face prosecution.
Underreporting or Concealing Income
Underreporting income or concealing income sources attracts severe penalties under Section 270A. The tax department can impose a penalty of 50% of the tax payable on underreported income. This includes situations where you fail to report income from all sources, such as freelance earnings, rental income, or capital gains.
More serious is the penalty for misreporting income, which includes deliberate concealment, furnishing inaccurate particulars, or claiming bogus expenses. In such cases, the penalty jumps to 200% of the tax due. This hefty penalty serves as a deterrent against tax evasion.
Incorrect or Inaccurate Information
Providing wrong details in your ITR, whether regarding income, deductions, or personal information, can lead to notices from the Income Tax Department. While genuine mistakes can be rectified through revised returns (within the time limit), repeated errors or deliberate misstatements can attract penalties.
Common errors include wrong bank account numbers, incorrect PAN details of family members for claims, mismatched TDS details, or claiming ineligible deductions. Always verify details against Form 16, Form 26AS, and Annual Information Statement (AIS) before filing.
Not Reporting Foreign Assets or Income
If you hold foreign assets, bank accounts, or earn income from overseas sources, you must disclose these in your ITR under the Black Money Act and Schedule FA (Foreign Assets). Failure to report can result in penalties up to Rs 10 lakh under Section 271FA.
Additionally, willful concealment of foreign income or assets can lead to prosecution and penalties ranging from 300% to 1000% of the tax evaded, along with possible imprisonment.
Ignoring TDS Mismatches
Many taxpayers overlook mismatches between TDS claimed in their return and TDS credit shown in Form 26AS or AIS. When your claimed TDS doesn't match government records, your return may be processed with adjustments, leading to tax demand notices with interest.
Always reconcile your TDS certificates with Form 26AS before filing. If there are genuine discrepancies, contact the deductor to file correction statements.
Missing Advance Tax Payments
If your tax liability exceeds Rs 10,000 in a financial year, you're required to pay advance tax in installments. Failure to pay or short payment of advance tax attracts interest under Section 234B (1% per month on shortfall) and Section 234C (1% per month for deferment of installments).
Senior citizens not having business income are exempt from advance tax requirements.
Not Responding to Income Tax Notices
Ignoring notices from the Income Tax Department is a serious mistake. Whether it's a notice for ITR verification, discrepancy in income, or demand notice, you must respond within the specified timeline.
Failure to respond can lead to best judgment assessment, where the assessing officer determines your tax liability based on available information, often resulting in inflated demands, penalties, and potential prosecution.
Claiming Bogus Deductions or Exemptions
Claiming deductions or exemptions without proper documentation or eligibility can backfire during scrutiny. Common issues include claiming HRA while living in own house, inflating charitable donations, or claiming medical expenses without bills.
Tax officials can disallow such claims, recover tax with interest, and impose penalties up to 200% for misreporting.
