- COMMON TAX FILING MISTAKES TO AVOID
a) NOT CHOOSING THE CORRECT ITR FORM
Many salaried individuals with additional income sources such as shares, cryptocurrencies, or property mistakenly file ITR-1, thinking it covers all income types. Using the wrong ITR form can lead to your return being treated as defective, causing delays or notices.
How To Avoid It- Refer to the official ITR form guide based on your income type. Use e-filing tools that suggest the right form. With TaxOSmart, choose the right ITR form confidently for accurate, hassle-free filing every time.
Risk- Section 139(9): If not corrected, your return is treated as not filed—triggering notices.
b) NOT REPORTING ALL INCOMES, ASSETS AND LOSSES
Failing to disclose income from sources like interest, dividends, rent, or capital gains—even if small— is considered concealment. Additionally, unreported losses cannot be carried forward for set-off in subsequent years.
How To Avoid It- Always check Form 26AS, AIS, TIS and bank statements.
Penalty- 50%-200% of the tax evaded (Section 270A, for underreporting/misreporting).
Penalty- 50%-200% of the tax evaded (Section 270A, for underreporting/misreporting).
FORM 26AS
AIS expands on Form 26AS by including not just TDS/TCS and property details, but also savings interest, dividends, rent, securities and property transactions, foreign remittances, and GST turnover. It offers a comprehensive view of your financial transactions reported to the tax department and allows you to verify and give feedback on the data before filing your return.
TIS
TIS is a category-wise summary of financial transactions linked to a taxpayer’s PAN or Form 60/61. It is generated from the AIS and includes aggregated data on income, taxes, and other financial activities. TIS helps in verifying reported information and is used to prefill the Income Tax Return for easier and more accurate filing.
Form 26AS is an Annual Consolidated Tax Statement issued by the Income Tax Department, showing details of TDS, TCS, advance tax, refunds, and defaults in TDS payments.
AISAIS expands on Form 26AS by including not just TDS/TCS and property details, but also savings interest, dividends, rent, securities and property transactions, foreign remittances, and GST turnover. It offers a comprehensive view of your financial transactions reported to the tax department and allows you to verify and give feedback on the data before filing your return.
TIS
TIS is a category-wise summary of financial transactions linked to a taxpayer’s PAN or Form 60/61. It is generated from the AIS and includes aggregated data on income, taxes, and other financial activities. TIS helps in verifying reported information and is used to prefill the Income Tax Return for easier and more accurate filing.
c) MISMATCH BETWEEN ITR AND FORM 26AS / AIS / TIS
Discrepancies between your ITR and details in Form 26AS, Annual Information Statement (AIS), or Taxpayer Information Summary (TIS) can trigger red flags. Always cross-verify your reported income, TDS, and transactions before submitting your return.
Risk- Refund delays, automated notices for mismatches.
Penalty- Possible interest for excess refund claimed.
Penalty- Possible interest for excess refund claimed.
d) NOT REPORTING FOREIGN INCOME OR ASSETS
With increasing information exchange under global treaties, failing to report foreign bank accounts, assets, or secondary income can result in the risk of penalty under the Black Money Act.
Penalty- Non-disclosure of foreign assets and income can lead to a penalty of Rs. 10 lakhs (Black Money Act, Section 43)
e) NOT UPDATING BANK DETAILS
Not disclosing all bank accounts - Incorrect or outdated bank details may delay refunds or cause return processing issues. Ensure your IFSC, account number, and bank name are accurate and linked with your PAN.
How To Avoid It- Before you submit your return, double-check your account number and IFSC code, validate bank account and connected to your PAN and Aadhaar.
f) DELAY IN FILING OR REVISED RETURNS AFTER NOTICES
The most avoidable mistake is missing the due date. For most individual taxpayers, the deadline for FY 2024-25 is 15th September 2025 (extended from July 31). If you miss this date, you can file a belated return until 31 December 2025, but late filing fees and interest will apply.
• Late filing penalty from ₹ 1000 to ₹ 5000 (section 234F)
• Interest under Sections 234A, 234B and 234C
• No carry forward losses
• Interest under Sections 234A, 234B and 234C
• No carry forward losses
g) INCORRECTLY CLAIMING WRONG OR EXCESSIVE DEDUCTION OR CREDITS
Claiming deductions or exemptions without proper eligibility or documentation, such as under Sections 80C, 80D, or HRA, can result in scrutiny or rejection with penalty.
Penalty- 200% of underreported tax, prosecution in extreme cases.
h) NOT E-VERIFYING THE RETURN
If the ITR is not verified within 30 days, it will be deemed as invalid. However, if verified after 30 days, it will be processed by the Income Tax Department considering the ITR filing date as date of verification.
Illustration- If ITR is filed on 22nd August 2025 & e-verified up to 21st September 2025, date of filing will be treated as 22nd August 2025.
However, if it is verified after 21st September 2025 (let’s say 10th October 2025), then date of filing will be considered as 10th October 2025 and ITR will be processed accordingly. Consequences of filing the ITR after the due date shall be applicable in such circumstances.
How To Avoid It- Use Aadhaar OTP, EVC, net banking, or a Digital Signature Certificate (DSC) to verify immediately after filing.
i) IMPROPER TAXATION OF VIRTUAL DIGITAL ASSETS (SECTION 115BBH)
Since AY 2023–24, income from Virtual Digital Assets (VDAs), including cryptocurrencies, must be disclosed and taxed at 30%. Non-reporting is treated as concealment and may attract penalties up to 50% of the tax on underreported income. Maintain detailed records of purchases and sales with timestamps.
How To Avoid It- Understand what kind of VDA you have. Maintain purchase and sale records with timestamps.
Choosing between the old and new tax regime is important especially for businesses using Form 10-IEA. Filing under the wrong regime without proper understanding can lead to higher tax liabilities.
How To Avoid It- Compare both tax regimes and file returns correctly. Check out the Income Tax Compliance Guide FY 2025-26 (AY 2026-27).
k) INCORRECT DECLARATION OF RESIDENTIAL STATUS
Your tax residential status –Resident, Non-resident (NR), Resident but not ordinarily resident (RNOR) affects your tax liability. Incorrect declaration can result in wrong tax liability, trigger scrutiny, and attract severe penalties—ranging from 50% to 200% under section 270A of tax avoided and possible prosecution under Section 277 of the Income Tax Act.
How To Avoid It- Keep track of the number of days stayed in India to calculate your residential status and tax treatment as per Section 5, 6, 9 and other income tax rules.
Residential Status Chart (India - Income Tax)
| STATUS | CONDITIONS | MEANING |
| Resident (Ordinary Resident) | Stay in India for: ≥ 182 days in the FY, OR ≥ 60 days in the FY AND ≥ 365 days in last 4 FYs AND satisfies both: • Resident in 2 out of 10 previous FYs • Stayed in India ≥ 730 days in last 7 FYs | Full tax liability in India (Global Income Taxed) |
| Resident but Not Ordinarily Resident (RNOR) | Satisfies basic condition of Resident BUT fails either: • Resident in 2 out of 10 previous FYs • Stay ≥ 730 days in last 7 FYs | Taxed only on Indian income + income from business/profession controlled from India |
