10 Common ITR Filing Mistakes to Avoid in year 2025-26

Filing Income Tax Returns (ITR) has become easier, as there are now two options for filing. Either you can go for an online process or an offline process. However, taxpayers can still make some mistakes. It is very important to know such common mistakes. This article will help you with that.

Let’s understand in detail such common errors:

1. Selecting Wrong ITR Form

One of the major mistakes that taxpayers make is selecting the wrong ITR form. Every form is meant for a different type of taxpayer, and using the wrong one can lead to rejection.

• ITR 1 is for salaried taxpayers with one house property and other sources.
• ITR 2 is for an individual or Hindu Undivided Family (HUF) without business income.
• ITR 3 is for an individual or HUF that earns income from a business or profession.
• ITR 4 is for taxpayers with presumptive income from a business or profession.

2. E-verification

Another important step people miss is e-verification. Merely filing the ITR is not enough; you must also verify it online within 30 days using Aadhaar OTP, net banking, or other methods. If your e-verification is not done, your return will be considered as not filed.

3. Incorrect details

Many taxpayers also enter wrong or incorrect details. These details include name, PAN, address, or assessment year. This can cause delays in refunds or trigger issues.

4. Wrong assessment/tax regime

Selecting the wrong assessment year and tax regime can result in higher taxes or missed deductions, so it should be done carefully.

5. Not Disclosing Full Income

Another mistake taxpayers make is not reporting all sources of income. Even if some income is exempt, it must still be declared and then claimed as exempt. Not reporting income from salary, rent, interest, or capital gains can lead to serious consequences.

6. Collecting Form 16

Salaried individuals who have worked with more than one employer should collect Form 16 from all employers. Missing this can lead to wrong income reporting.

7. ITR documents

Taxpayers must match their ITR details with Form 26AS and AIS, which show TDS, TCS, and tax payments. Any mismatch can cause refund delays or tax demands.

8. Claiming exemption

Taxpayers often forget to claim exemptions on capital gains under sections 54, 54EC, or 54F, which can help reduce tax liability.

9. Advance Tax

Taxpayers must also pay advance tax on time in four instalments during the year to avoid interest or consequences.

10. Ignoring Income Tax Notice

Sometimes, taxpayers ignore notices from the income tax department, which can create bigger problems. So it is important to respond quickly and correctly if any communication is received.
