Quick answer. Go to incometax.gov.in → Quick Links → “Link Aadhaar”. You first pay a Rs 1,000 late-linkage fee through e-Pay Tax (Challan ITNS 280, Minor head 500), wait 4-5 working days for the challan to reflect, then submit the linkage request. Total time: about 1 week if names match, 2-3 weeks if they don't.
Manoj Sharma, 38, IT consultant from Pune. Got a notice from his bank in March 2025 that his PAN would go “inoperative” if not linked to Aadhaar. Tried to link the same day — and ran into the most common stuck reason in India.
“I paid the Rs 1,000 challan on 15 March 2025 from the e-Pay Tax portal. The next day I clicked Link Aadhaar — error: 'Name mismatch with Aadhaar database'. Turns out my PAN said Manoj Kumar Sharma (full name) and my Aadhaar said Manoj Sharma (no middle name). I went to myaadhaar.uidai.gov.in, paid Rs 50, uploaded my class-X marksheet as proof, and added 'Kumar' as my middle name. UIDAI took 8 days to update. On 26 March I retried the linkage — success on the first attempt, SMS confirmation in 2 hours. Total cost: Rs 1,050. Total time: 11 days. If I had checked names first, I would have saved 10 days.”
—Manoj, March 2025
If you have a PAN and an Aadhaar — and you have not yet linked them — you must do it now. Since 1 July 2023, an unlinked PAN becomes “inoperative”, which means: TDS deducted at 20% instead of your slab rate (Section 206AA), no income-tax refund, no e-filing of returns, no big mutual-fund or bank transactions, and your KYC at every financial institution starts to break.
The Income Tax Act, Section 139AA (inserted by the Finance Act 2017), makes it mandatory for every person who has both a PAN and is eligible for Aadhaar to link the two. The Central Board of Direct Taxes (CBDT) extended the deadline several times between 2017 and 2023, but the final cut-off — 30 June 2023 — passed. Anyone linking after that date pays a Rs 1,000 fee under Section 234H.
You need to link if:
You are exempt if you fall into any of these categories under CBDT Notification 37/2017:
If you are exempt, you should still confirm your status on the portal — sometimes the system still flags an “inoperative” warning and you need to submit a one-time declaration.
This is the single biggest reason linkage fails. Before you pay anything, do this 30-second check:
If you see “Your PAN is already linked” — you're done, nothing to do. If you see “Your PAN is not linked” — proceed. If the system shows your name in two columns and they look different (extra middle name, dot, initial, spelling change), fix the mismatch first (see Step 5 of “Common stuck reasons” below) before paying the fee.
This is Challan No. ITNS 280, Minor Head 500 (Other Receipts). The challan reflects on the e-filing system in 4-5 working days — sometimes faster, sometimes slower around month-end.
After 4-5 working days:
If the challan has been credited and names match, you get “Your request for linking of Aadhaar has been submitted” within 30 seconds, and an SMS confirmation in 2-24 hours.
Possible results:
For people without internet access, Protean (NSDL) and UTIITSL authorised PAN service centres can do the linkage for you. Carry: PAN card, Aadhaar card, Rs 1,000 fee + Rs 50-100 service charge. They submit on your behalf and give you an acknowledgement slip.
Item Amount Mode ---------------------------------------------------------------- Late linkage fee (Section 234H) Rs 1,000 e-Pay Tax (challan ITNS 280, Minor 500) Aadhaar name update (if mismatch) Rs 50 myaadhaar.uidai.gov.in / ASK PAN name correction (if mismatch) Rs 110 Protean/UTIITSL form CSF PAN service centre handling fee Rs 50-100 Cash at counter SMS confirmation Free Auto from incometax.gov.in ---------------------------------------------------------------- Statutory deadline Already passed (30 June 2023) Inoperative-PAN penalty 20% TDS (Section 206AA), refund freeze
These are listed by frequency from the e-filing helpdesk's own internal notes (RTI-disclosed, FY 2024-25):
For Aadhaar-side mismatches (the actual root cause in most stuck cases), the relevant authority is UIDAI — not Income Tax. UIDAI helpline: 1947 (24×7). For Aadhaar update grievances see RTI for Aadhaar update rejected.
RTI helps here when: (1) your challan has been paid but not reflected in the system after 7+ working days, (2) you have submitted a linkage request but the status is stuck on “in progress” for more than 30 days, (3) e-Nivaran ticket has been auto-closed without resolution.
File the RTI to: The Public Information Officer, Centralized Processing Center (CPC), Income Tax Department, Bengaluru-560500. Fee: Rs 10 by IPO. Ask:
For the deeper mechanics, refund-side and TDS-side RTI is covered in RTI for TDS/IT refund delayed (your refund is the most common downstream stuck-symptom of an unlinked PAN).
RTI does NOT help when: (1) the issue is a name/DOB mismatch — the fix is at UIDAI or Protean, not by asking a question, (2) you are statutorily exempt (NRI, 80+, J&K/Assam/Meghalaya resident) — file a self-declaration instead, (3) you don't have a valid Aadhaar at all — get Aadhaar first.
Q. My PAN is showing inoperative. Can I still file my income-tax return?
You can attempt to file but the return will be rejected at upload. Pay the Rs 1,000 fee, link, then file. Penalty under Section 234F (Rs 1,000-5,000 for late filing) applies separately if you miss the ITR deadline.
Q. I paid the challan twice by mistake. Can I get a refund?
The duplicate Rs 1,000 sits as an “advance tax” credit on your PAN and is automatically adjusted against your next ITR. You can also claim refund through Form 26B but it takes 6-12 months.
Q. My Aadhaar mobile number is changed. How do I get OTP?
You can't — the OTP only goes to the Aadhaar-registered mobile. Visit any Aadhaar Seva Kendra with your old number proof, update mobile (Rs 50), then retry linkage. See RTI for Aadhaar update rejected if the update itself is stuck.
Q. Is the Rs 1,000 fee waived for senior citizens or BPL?
No — Section 234H makes no exception by income or age. The exemption is by category only (NRI, 80+, certain states).
Q. What if I link, but then update my Aadhaar later — does the link break?
No. The linkage is a one-time mapping of PAN to Aadhaar number. Updates to Aadhaar demographic data after linkage do not break the link. However, a change of Aadhaar number (extremely rare, e.g., after a documented identity dispute) will require re-linkage.
Q. Can my CA or tax consultant link on my behalf?
Yes, if you give them your e-filing login. But the OTP still goes to your Aadhaar-registered mobile, so you must be reachable for the 60-second OTP window.
Q. The portal keeps timing out at peak hours. When is the best time?
Late evening (10 PM - 1 AM) and early morning (5 AM - 7 AM) on weekdays. Avoid 31 March, 31 July, and 31 December — peak deadline traffic.
Q. My PAN was issued by a now-defunct UTI office in 1998 and I've never filed an ITR. Do I still need to link?
Yes — Section 139AA does not depend on whether you file ITRs. Any individual holding a PAN as on 1 July 2017 (and not in the exempt categories) must link. Inactive PANs of senior citizens and homemakers are the largest pool of inoperative cases as of 2026.
Q. After linkage, does my PAN data get pushed to my bank automatically?
No — linkage is between PAN and Aadhaar at CBDT's database. Banks/MFs/depositories pull this status periodically (typically monthly) via API. If your bank still shows PAN inoperative 30 days after successful linkage, hand them a fresh “Link Aadhaar Status” screenshot — they'll re-trigger their KYC refresh.
Q. I am a minor with a PAN issued for an investment. Do parents need to link?
Section 139AA applies to all PAN holders. For minors, the Aadhaar of the minor must be linked (parent/guardian acts on behalf). Use myaadhaar OTP login on the parent's mobile (if registered).
The inoperative-PAN regime is now strictly enforced. As of FY 2025-26, CBDT system-flags inoperative PANs in real time at the time of large transactions. Practical consequences citizens are reporting in 2026:
Linking takes one afternoon and Rs 1,000 — far cheaper than the cascading consequences of waiting.
