How to Link Aadhaar to PAN Online: Complete Guide (2026)

Last updated: August 2026

Quick answer: To link Aadhaar with PAN online, visit the Income Tax e-filing portal, pay the ₹1,000 late fee under the “e-Pay Tax” option (minor head “Fee for delay in linking PAN with Aadhaar”), then submit the linking request under “Link Aadhaar” using your PAN and Aadhaar number. The free linking window closed years ago, so almost every taxpayer completing this process now must pay the fee first.

Is There a PAN-Aadhaar Link Last Date Extended in 2026?

No general extension is currently in effect. The original free deadline was June 30, 2023. A narrower deadline of December 31, 2025 applied only to taxpayers who had obtained PAN using an Aadhaar enrolment ID instead of their actual Aadhaar number, and that window has also closed. As of August 2026, the government has not announced any fresh extension, so anyone linking PAN and Aadhaar today falls outside every free window and must pay the ₹1,000 fee.

This distinction matters because search results and forwarded messages about a “PAN Aadhaar link date extended” often refer to the 2023 or 2025 extensions, which are now history, not a live relief window. A taxpayer checking today should assume the fee applies unless they fall into one of the exempt categories described later in this guide.

Timeline of Aadhaar-PAN Linking Deadlines

What Is Aadhaar-PAN Linking and Why Is It Mandatory

Aadhaar-PAN linking is the process of connecting a person’s 12-digit Aadhaar number to their 10-digit Permanent Account Number on Income Tax Department records, so both identifiers point to a single verified taxpayer profile. The requirement flows from Section 262(6) of the Income Tax Act, 2025, which took effect April 1, 2026 and replaced the earlier Section 139AA of the Income Tax Act, 1961 on this point.

Every individual who held a PAN as of July 1, 2017 and is eligible to obtain Aadhaar must complete this linking, unless they fall under a specific statutory exemption. The Income Tax Department introduced the requirement to eliminate duplicate and fraudulent PAN cards, since Aadhaar’s biometric verification makes it far harder to hold multiple PANs under different names. An estimated crores of PAN cards were flagged as duplicate or non-existent entities before this linkage drive began, which is the underlying policy reason the rule has stayed in force through two different Income Tax Acts.

Aadhaar-PAN Link Fees: How Much It Costs in 2026

The Aadhaar-PAN link fee is a flat ₹1,000, payable once regardless of how long the PAN has been inoperative. This is a statutory late fee under Section 430 of the Income Tax Act, 2025 (previously Section 234H of the 1961 Act, inserted by the Finance Act, 2021). It is not negotiable, cannot be waived on request, and must be paid before the system will accept the linking request.

The fee has stayed at ₹1,000 since the original tiered structure (₹500 for intimation between April and June 2022, ₹1,000 thereafter) collapsed into a single flat rate once the June 2023 deadline passed. Taxpayers pay it through the “e-Pay Tax” service on the income tax portal, under the minor head “Other Receipts (500) – Fee for delay in linking PAN with Aadhaar.” The payment is separate from, and in addition to, any other tax liability the person may owe; it does not count against advance tax or self-assessment tax dues.

Documents and Details Needed Before Linking

A taxpayer needs three things ready before starting: an active PAN card, an Aadhaar number linked to a working mobile number, and the ₹1,000 fee payment method. No physical document upload is required; the entire process runs on number matching and OTP verification.

The Aadhaar must have a mobile number registered against it, since the OTP that confirms the linking request goes to that number, not to the number registered with the income tax portal. A common failure point is a taxpayer whose Aadhaar mobile number is old or disconnected; in that case, linking cannot proceed until the mobile number is updated at an Aadhaar Seva Kendra first. The name, date of birth, and gender on PAN and Aadhaar should also match, since the validation step compares these fields directly against UIDAI records.

How to Link Aadhaar to PAN Online: Step-by-Step

Linking Aadhaar with PAN card online happens in two stages on the Income Tax e-filing portal: paying the fee, then submitting the actual link request. Both must be completed in sequence, since the system will not process a linking request without a matching fee payment on record.

Step 1: Pay the ₹1,000 fee through e-Pay Tax
Go to incometax.gov.in and open the “e-Pay Tax” option under Quick Links, without logging in. Select the applicable Act (Income Tax Act, 2025, for payments made from April 2026 onward), enter the PAN, confirm it, and enter a mobile number to receive an OTP.

Step 2: Complete OTP verification
Enter the OTP sent to the registered mobile number. The portal redirects to the e-Pay Tax payment page automatically once verification succeeds.

Step 3: Select the correct payment head
Choose “Income Tax” as the tax category, select the relevant tax year, and pick “Other Receipts (500)” as the type of payment. This is the specific head reserved for the Aadhaar linking fee, so selecting the wrong head can cause the payment to not reflect against the PAN.

Step 4: Pay ₹1,000 and save the receipt
Complete payment through net banking, debit card, or UPI. Download and retain the challan; the linking request may take a day or two to recognize the payment.

Step 5: Submit the Aadhaar-PAN link request
Return to the e-filing portal homepage and click “Link Aadhaar” under Quick Links. Enter the PAN and Aadhaar number exactly as they appear on both documents, then click “Validate.”

Step 6: Verify name match and confirm
The system checks that the name, and in most cases date of birth, matches across both documents. Minor mismatches such as initials versus full names sometimes still pass; significant mismatches will require correcting one document first.

Step 7: Track the linking status
Once submitted, the request status shows as “Pending” while the system validates it against UIDAI records. This typically resolves within a few days, though the Income Tax Department states reactivation of an inoperative PAN can take up to 30 days from a successful link.

How to Check PAN-Aadhaar Link Status

A taxpayer can check whether their PAN and Aadhaar are already linked without logging in. On the e-filing portal, open “Link Aadhaar Status” under Quick Links, enter the PAN and Aadhaar number, and click “View Link Aadhaar Status.” The result shows one of three states: already linked, pending (fee paid, validation in progress), or not linked.

Checking status first is worth doing before paying the fee a second time. Many taxpayers assume their PAN is unlinked simply because a bank or broker flagged it, when in fact the earlier linking request is still sitting in “Pending” status with UIDAI. Paying the fee again in that situation does not speed up processing and creates a duplicate payment that then needs a refund claim.

What Happens If PAN Is Not Linked to Aadhaar

An unlinked PAN becomes “inoperative,” which is functionally different from being cancelled but carries most of the same practical consequences. An inoperative PAN cannot be used to file an income tax return, and any return already filed with an inoperative PAN is treated as if PAN was not quoted at all.

Consequences of an inoperative PAN include:

• Income tax returns cannot be filed until the PAN is reactivated through linking
• Pending refunds are frozen and do not accrue interest during the inoperative period
• TDS and TCS get deducted or collected at higher rates, since an inoperative PAN is treated as PAN not furnished
• High-value financial transactions that legally require PAN, such as large cash deposits, property purchases, or mutual fund investments above prescribed limits, become difficult or impossible to complete
• Bank accounts, demat accounts, and trading accounts linked to that PAN may face restrictions from the institution

None of these consequences are permanent. Once the linking request is validated, the PAN becomes operative again and normal transactions resume, though refunds withheld during the inoperative window are released only after reactivation, without interest for that period.

To see how this plays out in practice: a salaried taxpayer with an inoperative PAN who sells mutual fund units will typically see TDS deducted at 20% instead of the usual 10% or lower slab rate, since Section 206AA treats an inoperative PAN the same as no PAN at all. That extra amount is not lost permanently; it can be claimed back only after the PAN is reactivated and the taxpayer files a return for that year, which means the money stays locked up for months rather than being available immediately.

Common Mistakes That Delay Aadhaar-PAN Linking

Paying the fee under the wrong assessment or tax year. The payment head must correspond to the current tax year selection on the portal; a payment logged against the wrong year sometimes fails to match automatically with the PAN, which then requires a grievance filing to correct.

Assuming the exemption is permanent. NRIs and other exempt categories who later obtain Aadhaar, or whose residential status was never updated on the portal, frequently discover their “exempt” PAN has gone inoperative without warning.

Not checking status before re-paying. As noted earlier, a request already in “Pending” validation does not need a second fee payment. Portal delays of a few days are normal and do not indicate a failed request.

Ignoring a name or date-of-birth mismatch. The system does not always reject a mismatched request outright; sometimes it stays in a perpetual “Pending” state instead. If a request has not resolved after a week, checking for a data mismatch between PAN and Aadhaar records is the first thing to verify.

Income Tax Act 2025 vs 1961: What Changed for This Rule

The Income Tax Act, 2025 came into force April 1, 2026 and replaced the Income Tax Act, 1961 in full, renumbering nearly every section in the process. For PAN-Aadhaar linking specifically, the substance of the rule has not changed, only its location in the statute book.

Anyone reading older articles or CBDT circulars that cite “Section 139AA” or “Section 234H” is reading accurate information about the same rule; those sections simply describe the position under the law that governed income up to March 31, 2026. Payments and filings made from April 2026 onward reference the new section numbers instead.

Who Is Exempt From Aadhaar-PAN Linking

Four categories of PAN holders are exempt from the linking requirement under the CBDT notification that first defined this rule in 2017, and the exemption carries forward under the Income Tax Act, 2025:

• Residents of Assam, Meghalaya, and Jammu & Kashmir
• Non-resident Indians, as defined under the Income Tax Act
• Individuals aged 80 years or above at any point during the relevant year
• Foreign citizens who are not citizens of India, including OCI and PIO cardholders

Falling into an exempt category is not automatic protection against an inoperative PAN. If an exempt person voluntarily obtains an Aadhaar number, they become “eligible” to link under the same provision that governs everyone else, and the exemption stops applying. NRIs who already hold Aadhaar, for instance, are expected to link it or formally update their residential status to “Non-Resident” on the income tax portal to avoid their PAN being marked inoperative by the system’s automated checks.

What Experts Say

Tax practitioners consistently flag two points about the current PAN-Aadhaar linking rules. First, the ₹1,000 fee under Section 430 is a one-time charge regardless of delay length, so taxpayers who assume the amount grows the longer they wait are working from outdated information; that tiered structure ended when the original 2023 deadline passed. Second, practitioners note that within the special window that closed December 31, 2025, taxpayers who had received PAN through an Aadhaar enrolment ID could complete linking without any penalty, a detail that a number of taxpayers missed because most general guidance at the time referenced only the earlier 2023 deadline.

Chartered accountants handling NRI clients have also pointed out a recurring gap: many overseas taxpayers assume the NRI exemption is permanent and automatic, when in practice the Income Tax Department’s system checks Aadhaar eligibility dynamically. An NRI who has ever obtained Aadhaar, even years before moving abroad, can still see their PAN marked inoperative unless their residential status is correctly updated on the portal.

This guide draws on the Central Board of Direct Taxes notification dated April 3, 2025, and the Income Tax Department’s published FAQs on PAN, rather than individual practitioner commentary, since verified statutory text is the more reliable source for a compliance deadline that has changed multiple times since 2017.
