ITR validation errors are one of the most common hurdles faced by taxpayers each year while filing income tax returns. These errors occur due to data mismatches, incomplete details, or incorrect form usage during e-filing. The Income Tax Department’s system automatically flags such inconsistencies to maintain accuracy and compliance. Understanding these validation checks and knowing how to correct them helps prevent delays, refund issues, or notices. TaxBuddy simplifies this process by offering guided error resolution and ensuring that every return passes all validation checkpoints seamlessly.

Understanding ITR Validation Errors
ITR validation errors occur when the Income Tax e-filing system detects inconsistencies or missing details in a taxpayer’s return. These errors are not always technical; they often arise from incorrect data entry, mismatched income details, or failure to use the right ITR form. The validation process ensures that every return complies with the Income Tax Department’s prescribed rules before submission. Ignoring such errors can lead to defective return notices, refund delays, or even rejections. Identifying and resolving them early makes the filing process smoother and prevents unnecessary follow-ups or rectification requests later.
Common ITR Validation Errors and How to Fix Them
The most frequent validation errors stem from mismatched details, incomplete data, or incorrect form selection. Some of the common issues include:
Form 26AS or AIS Mismatch: Occurs when the TDS figures or income data in Form 26AS or AIS differ from what’s entered in the ITR. The solution is to cross-check every income source and reconcile TDS details using the AIS feedback option.
Bank Account Not Validated: Refunds can get stuck if the bank account is not pre-validated. Taxpayers should ensure the account is active, PAN-linked, and correctly entered.
E-verification Failures: When Aadhaar OTP or EVC verification fails, the alternative is to print, sign, and send the ITR-V to CPC Bengaluru within 30 days.
Incorrect ITR Form Selection: Using the wrong ITR form automatically triggers validation errors. Choosing the correct form based on income sources resolves this issue.
Portal Login or Technical Errors: Sometimes, system overloads or browser incompatibility cause validation failures. Clearing cache, using supported browsers, or filing during off-peak hours helps.
These fixes ensure the return passes validation successfully and avoids rejection during processing.
Resolving Form 26AS and AIS Mismatch Errors
Discrepancies between Form 26AS, AIS, and ITR data are among the top reasons for validation errors. Such mismatches occur when TDS entries made by employers, banks, or investment platforms do not match the taxpayer’s reported income. To resolve these, compare each income entry line-by-line across all forms. If an error is found in AIS, use the “Feedback” option to flag or correct it. Once reconciled, update the correct figures in your ITR and revalidate. Using trusted tax-filing platforms like TaxBuddy can automate this comparison and reduce manual effort.
Fixing Bank Account Validation and Refund Delays
Bank validation is a mandatory step to ensure smooth refund processing. If the bank account linked to the ITR is inactive, closed, or not PAN-verified, refunds get delayed or rejected. Taxpayers should visit the “Profile Settings” section of the e-filing portal, check their bank status, and revalidate if needed. Common fixes include correcting mismatched names, ensuring the account belongs to the primary PAN holder, and updating IFSC details. In case of repeated validation failures, adding a new bank account and setting it as “Primary for Refund” can resolve the issue.
Handling E-verification and Portal Login Errors
E-verification is the final step in completing ITR filing. Failures in this step occur due to issues like expired OTPs, incorrect Aadhaar linkage, or network timeouts. The simplest way to fix this is to retry verification via alternative methods such as net banking, bank account EVC, or Demat account verification. If none of these options work, download the ITR-V acknowledgement, sign it physically, and send it by post to CPC Bengaluru within 30 days. For portal login errors, using incognito mode or switching devices often helps.
Selecting the Correct ITR Form for Error-Free Filing
Using the wrong ITR form is one of the primary causes of validation rejection. Each form caters to specific income categories—ITR-1 for salaried individuals, ITR-2 for capital gains, ITR-3 for business income, and so on. Selecting the incorrect form leads to mismatched data and validation errors. Before filing, taxpayers should review income sources, deductions, and residency status to ensure proper form selection. TaxBuddy’s guided filing system helps automatically identify the right ITR form, minimizing the risk of such errors.
Step-by-Step Process to Resolve ITR Validation Errors
Review the error message shown on the portal and note the field or section mentioned.
Compare the data in your ITR with Form 16, 26AS, AIS, and bank statements.
Correct any inconsistencies such as wrong TDS amounts or unreported income.
Ensure your bank account and Aadhaar details are validated.
Use the “Validate” button on the e-filing portal or offline JSON utility to recheck the return.
Re-upload the corrected ITR and verify it.
If errors persist, contact the Income Tax helpline or use expert support available on TaxBuddy for quick resolution.
Latest Rules, Updates, and CBDT Notifications
For AY 2025–26, the Central Board of Direct Taxes (CBDT) has updated the validation framework to include stricter cross-checks for income, TDS, and deductions. CBDT Circular No. 06/2025 specifies the updated deadline for filing and the new format for bank validation. Additionally, the e-filing portal now runs automated comparisons between AIS and ITR entries, flagging even minor discrepancies. Taxpayers are encouraged to refer to the latest ITR validation rules published on the Income Tax portal before submission. Staying updated helps ensure compliance and minimizes the risk of defective returns.
Avoiding Future ITR Validation Errors
Preventing validation errors begins with maintaining accurate and updated financial records throughout the year. Ensure that every income and TDS entry matches what is reported by employers, banks, and mutual fund houses. Always download the latest Form 26AS and AIS before filing, and review them carefully. Use the official portal or reliable tax-filing services like TaxBuddy, which run pre-validation checks automatically. Filing early also reduces last-minute portal congestion and technical issues that lead to validation errors.

FAQs
Q1. Does TaxBuddy offer both self-filing and expert-assisted plans for ITR filing, or only expert-assisted options?
TaxBuddy provides both self-filing and expert-assisted plans to suit different user needs. The self-filing option allows taxpayers to upload their Form 16 and other documents to file their ITR independently using AI-guided tools. For those seeking personalised guidance, the expert-assisted plan connects users with qualified tax professionals who review, validate, and submit returns on their behalf. This dual offering ensures flexibility and convenience for all types of taxpayers.
Q2. Which is the best site to file ITR?
The official Income Tax e-filing portal is the government’s primary website for filing income tax returns. However, many taxpayers prefer using reliable third-party platforms like TaxBuddy for their ease of use, error detection, and expert support. TaxBuddy offers automated validation checks, instant TDS reconciliation, and real-time filing assistance, making it one of the best online solutions for both salaried and self-employed individuals.
Q3. Where to file an income tax return?
Income tax returns can be filed online through the official portal of the Income Tax Department (www.incometax.gov.in) or through trusted digital platforms like TaxBuddy. These platforms allow users to upload documents, validate data, and file their returns directly with the Income Tax Department. Filing online is faster, safer, and ensures immediate acknowledgement once the return is successfully submitted.
Q4. What causes ITR validation errors?
ITR validation errors usually occur when the information entered in the return doesn’t match the data available in government databases like Form 26AS, AIS, or PAN-linked records. Other causes include using the wrong ITR form, failing to pre-validate a bank account, incorrect Aadhaar-PAN linkage, or missing mandatory details. These errors are part of the system’s automatic checks to ensure returns are accurate and compliant before submission.
Q5. How can I fix a Form 26AS or AIS mismatch while filing my ITR?
To fix a mismatch, start by downloading the latest versions of both Form 26AS and the Annual Information Statement (AIS) from the Income Tax portal. Compare the income, TDS, and investment details line by line with your ITR entries. If the difference arises due to an incorrect entry in AIS, you can use the “Feedback” option within AIS to flag or correct it. Once the figures are reconciled, update your ITR and run validation again before submission.
Q6. Why is my e-verification failing even after submitting my return?
E-verification can fail due to multiple reasons, such as incorrect Aadhaar linkage, expired OTPs, or mismatched details between PAN and Aadhaar. In such cases, try alternative verification methods like net banking, bank account EVC, or Demat account verification. If these also fail, download the ITR-V acknowledgement, sign it, and send it via post to CPC Bengaluru within 30 days of filing to complete the verification process.
Q7. What should I do if the income tax portal shows an invalid bank account for refunds?
If your bank account is marked invalid, it means it hasn’t been successfully pre-validated or linked with your PAN. Visit the “Profile Settings” section on the Income Tax portal, select “My Bank Account,” and revalidate your account. Ensure that your name, account number, and IFSC match your bank’s records. If validation continues to fail, you can add a new active account and mark it as the “Primary for Refund.”
Q8. Can validation errors delay my income tax refund?
Yes. Validation errors can delay refunds since the Income Tax Department processes returns only after all discrepancies are resolved. For instance, if your bank account isn’t validated or your TDS entries don’t match with Form 26AS, the system may hold the refund until corrections are made. Once the issues are fixed and the return is successfully validated, refunds are typically credited within 7 to 15 business days.
Q9. How do I ensure my ITR form selection is correct?
Choosing the right ITR form depends on your sources of income. For example, ITR-1 applies to salaried individuals with income up to ₹50 lakh, ITR-2 is for those with capital gains, and ITR-3 suits business or professional income. The Income Tax Department provides detailed guidelines for each form on its portal. Alternatively, TaxBuddy’s system automatically identifies the correct ITR form based on uploaded documents and financial data, reducing the chance of error.
Q10. Is it possible to revise my return if a validation error is found after filing?
Yes. If you discover any mistakes or validation errors after submitting your ITR, you can file a revised return under Section 139(5) of the Income Tax Act. The revision can be done before the deadline for that assessment year—usually December 31 of the relevant financial year. Once corrected, the revised return replaces the original and is considered your final valid submission.
Q11. What documents should be checked before running ITR validation?
Before validating your return, review key documents such as Form 16 (for salaried employees), Form 26AS, AIS, TIS, and bank statements. If you have investments or capital gains, check the mutual fund or share transaction summaries. Ensure your Aadhaar and PAN are linked, and your bank account is pre-validated. Having these documents ready helps prevent mismatched data and ensures successful validation on the first attempt.
Q12. How can TaxBuddy help in resolving complex validation errors quickly?
