ITR Filing Error on Income Tax Portal? Fix Common Errors

Filing your Income Tax Return (ITR) online should be straightforward, but many taxpayers face errors on the Income Tax e-Filing portal. From JSON upload failures to validation errors and server timeouts, these issues can be frustrating — especially close to the filing deadline.

This guide covers the most common ITR filing errors and how to fix each one step by step.

Common ITR Filing Errors and Solutions

1. JSON Upload Error

Error: "Error in uploading JSON" or "Invalid JSON file" when uploading your ITR.

Causes:

• JSON file was generated using an outdated offline utility
• File got corrupted during download or transfer
• Wrong ITR form was used to generate the JSON

How to Fix:

1. Download the latest version of the offline utility from incometax.gov.in
2. Go to Downloads → Offline Utilities → select the correct ITR form
3. Re-enter your details or import the previously saved XML
4. Generate a fresh JSON file
5. Upload the new JSON file on the portal

Tip: Always clear your browser cache before uploading the JSON file.

2. Validation Failed Error

Error: "Validation failed" or specific field-level validation errors.

Causes:

• Mandatory fields left blank (PAN, bank account, employer details)
• Mismatch between Form 26AS/AIS data and declared income
• Incorrect tax computation or deduction amounts

How to Fix:

1. Open the offline utility and click Validate before generating JSON
2. Check all mandatory fields marked with asterisk (*)
3. Cross-verify your income details with Form 26AS and Annual Information Statement (AIS) on the portal
4. Ensure total income, deductions under Section 80C, and tax payable are correctly calculated
5. Fix the flagged errors and regenerate the JSON

3. Server Error / Portal Timeout

Error: "Something went wrong," "Service temporarily unavailable," or portal not loading.

Causes:

• Heavy traffic on the portal, especially near filing deadlines
• Server maintenance or technical issues at CPC Bengaluru

How to Fix:

1. Try filing during off-peak hours — early morning (6-8 AM) or late night (after 10 PM)
2. Clear browser cache and cookies
3. Use Google Chrome or Mozilla Firefox (latest version)
4. Disable browser extensions that may interfere
5. If the error persists, try after a few hours — the IT department usually resolves server issues within 24 hours
6. Check the official IT portal Twitter handle for maintenance announcements

4. ITR Form Mismatch

Error: "You are not eligible to file this ITR form" or the wrong form gets pre-selected.

Causes:

• Selecting ITR-1 when you have capital gains (requires ITR-2 or ITR-3)
• Choosing ITR-1 when you have income from more than one house property
• Business income shown but filing ITR-1 instead of ITR-3 or ITR-4

How to Fix:

1. Check your income sources carefully
2. Select the correct ITR form
3. If you already started with the wrong form, go to e-File → Income Tax Returns → File Income Tax Return and select the correct form

5. Offline Utility Not Working

Error: Utility not opening, Java errors, or "utility has stopped working."

Causes:

• Java not installed or outdated
• Utility version is old
• System compatibility issues

How to Fix:

1. Install the latest version of Java (JRE 8 or above) from java.com
2. Download the latest offline utility from the portal's Downloads section
3. On Windows, right-click the utility and select Run as Administrator
4. If using Mac, ensure you have allowed the app in System Preferences → Security & Privacy
5. For persistent issues, use the online filing mode on the portal instead

6. Common ITR Error Codes

Step-by-Step: How to File ITR Online Without Errors

1. Log in to incometax.gov.in using PAN and password
2. Go to e-File → Income Tax Returns → File Income Tax Return
3. Select Assessment Year (e.g., AY 2026-27 for income earned in FY 2025-26)
4. Choose filing mode: Online (recommended) or Offline (upload JSON)
5. Select the correct ITR form based on your income type
6. Fill in income details — the portal pre-fills data from Form 26AS and AIS
7. Verify all pre-filled data and correct any mismatches
8. Enter deductions and tax payments
9. Click Validate to check for errors
10. Preview your return and submit
11. e-Verify your return immediately using Aadhaar OTP or net banking

Processing Time

• ITR processing by CPC: 15 to 45 days after e-verification
• Refund (if applicable): 30 to 120 days — see our ITR refund guide

Important Tips

1. Always use the latest utility — the IT department updates utilities frequently during filing season
2. File well before the deadline to avoid portal congestion and server errors
3. Keep Form 26AS and AIS handy to avoid income mismatch errors
4. e-Verify immediately after filing — unverified returns are treated as not filed
5. Take a screenshot of the acknowledgment number after successful filing

Frequently Asked Questions

Q1: Why does my ITR JSON file keep getting rejected?

The JSON file may be generated from an outdated utility or wrong ITR form. Download the latest utility from the official portal, select the correct form, and regenerate the JSON.

Q2: Can I file ITR if the portal shows a server error?

Yes, but you need to wait. Server errors are usually temporary. Try filing during off-peak hours (early morning or late night). You can also use the offline utility to prepare your return and upload when the server is stable.

Q3: What happens if I select the wrong ITR form?

The portal will show a validation error or reject the filing. You can restart the process and select the correct form. There is no penalty for selecting the wrong form — you simply cannot submit it.

Q4: How do I check if my ITR was successfully filed?

Log in to the e-Filing portal → e-File → Income Tax Returns → View Filed Returns. You will see the status, acknowledgment number, and verification status.

Q5: What should I do if the error persists after trying all fixes?

Contact the CPC helpline at 1800-103-0025 (toll-free) or raise a grievance on the e-Filing portal. You can also visit your nearest Income Tax office for assistance.

Q6: Is there a penalty for filing ITR late due to portal errors?

If the portal was genuinely down and the government extends the deadline, no penalty applies. Otherwise, late filing attracts a penalty of ₹1,000 to ₹5,000 under Section 234F. Always file before the deadline to avoid this.
