Filing your income tax return may seem like a routine task, but even small mistakes can lead to notices from the Income Tax Department of India, delayed refunds, or penalties. Every year, many taxpayers unknowingly make errors while submitting their returns through the Income Tax e-Filing Portal, as tax regulations continue to evolve in 2026, understanding the most common filing mistakes can help you avoid unnecessary stress and ensure a smooth tax filing experience.
We at JD Shah Associates, often see taxpayers repeating similar errors. In this article, we explain the most common income tax filing mistakes and how you can avoid them.
1. Choosing the Wrong ITR Form
One of the most common mistakes is selecting the incorrect ITR form. Different forms apply to different types of taxpayers depending on income sources such as salary, business income, or capital gains.
For example:
- Salaried individuals usually file ITR‑1 (Sahaj).
- Individuals with capital gains or multiple income sources may need ITR‑2.
- Business owners typically file ITR‑3.
Selecting the wrong form can make your return defective and may require correction later.
Tip: Always review your income sources before choosing the form.
2. Not Reporting All Sources of Income
Many taxpayers report only their salary income and forget to include other earnings such as:
- Interest from savings accounts or fixed deposits
- Rental income
- Freelance or side business income
- Capital gains from shares or mutual funds
These details are often reflected in Form 26AS or the Annual Information Statement (AIS).
If the income reported in your return does not match these records, the tax department may send a notice.
3. Claiming Incorrect Deductions
Taxpayers sometimes claim deductions without proper documentation or misunderstand eligibility rules under sections like Section 80C, Section 80D, or Section 80G.
Common mistakes include:
- Claiming deductions already considered by the employer
- Claiming ineligible expenses
- Entering wrong amounts
Incorrect deductions may result in additional tax liability or penalties later.
4. Not Reconciling TDS Details
Many taxpayers assume that the TDS deducted by their employer is always correct. However, mistakes can happen.
Before filing your return, always cross-check your TDS details with Form 16 and Form 26AS. If there is any mismatch, you should get it corrected before submitting your return.
5. Ignoring the New vs Old Tax Regime
Taxpayers in India can choose between the New Tax Regime and the Old Tax Regime. Many people simply select the default option without comparing which regime is more beneficial for them.
Choosing the wrong regime could mean paying more tax than necessary.
6. Filing Returns at the Last Minute
Waiting until the deadline often leads to rushed decisions and mistakes such as:
- Missing important income details
- Entering incorrect bank information
- Forgetting deductions
- Not verifying the return
Early filing gives you enough time to review your return carefully and fix any issues.
7. Forgetting to Verify the Return
Filing your return is not the final step. Your return must be verified within the specified time through:
- Aadhaar OTP
- Net banking
- Bank account verification
If the return is not verified, it will be treated as not filed, even if you submitted it online.
8. Providing Incorrect Bank Details
Incorrect bank account numbers or IFSC codes can delay your tax refund. Always double-check your bank details before submitting the return. This is especially important for taxpayers expecting refunds.
