Income Tax Portal Not Working? Fix Login & Filing Errors

The Income Tax e-Filing portal (incometax.gov.in) is the gateway for filing ITR, checking refunds, responding to notices, and managing your tax profile. But many users face issues — login failures, OTP not arriving, slow loading, and technical errors.

This guide covers the most common portal issues and how to fix them.

1. Login OTP Not Received

Problem: You enter your PAN/User ID and password, but the OTP for two-factor authentication does not arrive on your mobile or email.

Fixes:

1. Wait 2-3 minutes — OTPs can be delayed during peak hours
2. Click Resend OTP on the portal (you can resend up to 3 times)
3. Check your spam/junk folder for the email OTP
4. Ensure your mobile number and email are correct on the portal — go to Profile Settings to verify
5. If your mobile number has changed, visit your nearest Income Tax office with PAN card and ID proof to update it
6. Try a different method — switch between mobile OTP and email OTP
7. Clear browser cache and try in incognito/private mode

Tip: If you consistently don't receive OTPs, your mobile number registered with the IT department may be outdated. You can update it by visiting your nearest IT office.

2. Forgot Password / Account Locked

Problem: You forgot your password or your account got locked after multiple failed attempts.

How to Reset Password:

1. Go to incometax.gov.in → Click Login
2. Enter your User ID (PAN) and click Continue
3. Click Forgot Password
4. Choose a reset method:
   • OTP on registered mobile/email
   • Using Aadhaar OTP (if PAN-Aadhaar linked)
   • Using bank account EVC
   • Using Demat account EVC
5. Enter the OTP/EVC received
6. Set a new password following the rules:
   • Minimum 8 characters, maximum 14
   • At least one uppercase letter, one lowercase, one number, one special character
7. Click Submit

If Account Is Locked:

• Wait 24 hours — the account automatically unlocks
• Or reset your password immediately using the steps above

3. DSC (Digital Signature Certificate) Not Working

Problem: DSC not recognized, "DSC registration failed," or signing errors.

Fixes:

1. Ensure you have the emsigner utility installed and running
   • Download it from the portal's Downloads section
2. Check that your DSC is valid (not expired)
3. Your DSC must be registered on the portal:
   • Go to My Profile → Register DSC
   • Upload your certificate and verify
4. Use Google Chrome or Internet Explorer/Edge — some browsers don't support DSC plugins
5. Ensure the USB token driver is installed for your DSC dongle
6. Try running the emsigner as Administrator
7. Check that the PAN on your DSC matches your e-Filing PAN

4. Portal Loading Slowly or Not Opening

Problem: The portal takes too long to load, shows blank pages, or times out.

Fixes:

1. Clear browser cache and cookies completely
2. Use an updated browser — Google Chrome (latest) or Firefox (latest)
3. Disable ad blockers and browser extensions
4. Try in incognito/private browsing mode
5. Check your internet connection — try switching between Wi-Fi and mobile data
6. File during off-peak hours: early morning (6-8 AM) or late night (after 10 PM)
7. If using a VPN, disable it — the portal may block VPN connections
8. Try accessing from a different device (laptop vs mobile)

Note: The portal experiences heavy traffic during July (ITR filing deadline). Server slowdowns are common during this period.

5. Browser Compatibility Issues

Problem: Forms not loading, buttons not clickable, pages displaying incorrectly.

Recommended Setup:

Additional Steps:

1. Disable browser extensions — especially ad blockers and privacy extensions
2. Allow pop-ups from incometax.gov.in (the portal uses pop-ups for OTP and verification)
3. Enable JavaScript — the portal requires it
4. If using Safari on Mac, switch to Chrome — some features don't work on Safari
5. Don't use mobile browsers for complex operations like ITR filing — use a desktop browser

6. PAN-Aadhaar Mismatch / Link Error

Problem: "PAN-Aadhaar linking failed" or portal shows name/DOB mismatch.

Causes:

• Name in PAN and Aadhaar don't match exactly
• Date of birth differs between PAN and Aadhaar
• Gender mismatch

How to Fix:

1. Check the exact name, DOB, and gender on both documents
2. If Aadhaar details are correct, update your PAN:
   • Apply for PAN correction on NSDL or UTIITSL portal
   • Fee: ₹107 (including GST)
3. If PAN details are correct, update your Aadhaar:
   • Visit an Aadhaar enrolment centre or update online on myAadhaar portal
4. After correction, retry the PAN-Aadhaar linking:
   • Go to incometax.gov.in → Link Aadhaar (available on the homepage)
   • Or SMS: UIDPAN <12-digit Aadhaar> <10-digit PAN> to 567678

Deadline: PAN-Aadhaar linking is mandatory. Unlinked PANs become inoperative and cannot be used for filing ITR, opening bank accounts, or other financial transactions.

7. Other Common Portal Errors

Important Tips

1. Bookmark the correct URL — only use incometax.gov.in. Avoid search result links that may be phishing sites
2. Never share OTP or password with anyone — the IT Department never asks for it via call or email
3. Keep your profile updated — mobile number, email, and bank details
4. Use the official helpline for unresolved issues: 1800-103-0025 (toll-free)
5. Screenshot error messages before contacting support for faster resolution

Frequently Asked Questions

Q1: The Income Tax portal is completely down. What should I do?

Wait and try after a few hours. The IT Department posts maintenance schedules on the portal. If it's close to the filing deadline, the government usually extends the date for widespread outages.

Q2: I can't log in even with the correct password. Why?

Your account may be locked after multiple failed attempts. Wait 24 hours or reset your password. Also check if you're using PAN (not Aadhaar) as the User ID.

Q3: Can I file ITR using a mobile phone?

Yes, you can use the AIS for Taxpayer mobile app for simple returns (ITR-1, ITR-4). For complex returns, use a desktop browser for the best experience.

Q4: The portal accepted my ITR but I didn't get an acknowledgment. What now?

Log in and go to View Filed Returns. If your return shows as filed, download the acknowledgment from there. If it doesn't appear, the submission may have failed — try filing again.

Q5: How do I update my mobile number or email on the IT portal?

Log in → My Profile → Personal Details → update your contact information. You'll need to verify with OTP sent to both old and new numbers.

Q6: I see a "PAN is inoperative" message. What does this mean?

Your PAN has been deactivated because it is not linked with Aadhaar. Link your PAN with Aadhaar by paying the applicable fee (₹1,000) on the portal to reactivate it.
