How to Link PAN with Aadhaar Online: Step-by-Step Guide & Fee Payment

August 28, 2026

Linking your Permanent Account Number (PAN) with your Aadhaar number is a critical statutory mandate for taxpayers in India. Governed by Section 139AA of the Income-tax Act, 1961, and Section 262 of the Income-tax Act, 2025, this integration is essential for maintaining an active tax profile. While the original deadline to complete this process without a penalty expired on June 30, 2023, the Income Tax Department continues to allow late linking. However, this delayed process now requires the payment of a prescribed late fee of ₹1,000.

If you missed the original deadline, your PAN has likely become “inoperative.” An inoperative PAN restricts your ability to file Income Tax Returns (ITRs), claim pending tax refunds, or execute high-value financial transactions. Fortunately, the reactivation process is straightforward and can be completed entirely online. This comprehensive guide explains how to link PAN with Aadhaar online, covering eligibility rules, payment steps, and final submission procedures to help you restore your PAN to “operative” status safely.

Eligibility and Exemptions for PAN-Aadhaar Linking

The legal requirement to link PAN with Aadhaar applies to almost all individual taxpayers in India, but there are specific criteria and exemptions defined by the government. Understanding these rules will help you determine if you need to pay the late fee or if you are exempt from the process entirely.

As per the statutory guidelines, it is mandatory for all existing PAN holders who were allotted a PAN on or before July 1, 2017, to link it with their Aadhaar card. For individuals applying for a new PAN, this linkage is processed automatically during the application stage, meaning no additional steps or late fees are required.

However, the Ministry of Finance has exempted certain categories of individuals from this mandatory requirement. You are not legally required to link your PAN with Aadhaar if you fall under any of the following exempted categories:

Residents of the states of Assam, Jammu & Kashmir, or Meghalaya.
Non-Resident Indians (NRIs) or individuals classified as non-residents as per the Income-tax Act, 1961.
Individuals who are 80 years of age or older at any time during the previous financial year.
Individuals who are not citizens of India.

If you do not belong to any of these exempted categories and your PAN was issued on or before July 1, 2017, you must complete the linking process online to avoid long-term financial and tax-related complications.

Prerequisites and Documents Required Before Linking

Before initiating the online linking process, you must gather the necessary documents and ensure that your personal details match perfectly across both databases. Even minor discrepancies can cause the validation process to fail, resulting in delayed reactivation.

To complete the process, you will need the following items:

Permanent Account Number (PAN) Card: A valid, active, or inoperative PAN card.
Aadhaar Card: Your 12-digit Aadhaar number.
Active Mobile Number: A mobile number to receive One-Time Passwords (OTPs) during the payment and final validation stages.

A critical prerequisite for successful linking is that your personal details—specifically your Name, Date of Birth, and Gender—must be identical on both your PAN and Aadhaar cards. If there is a spelling mistake or a mismatch in your date of birth, the system will reject your linking request. In such cases, you must first correct the errors on either your PAN (via the Protean/NSDL or UTIITSL portals) or your Aadhaar (via the UIDAI portal) before attempting to link them.

Additionally, under Notification No. 26/2025 (dated April 3, 2025), individuals who originally obtained their PAN using an Aadhaar Enrolment ID must now complete their linkage using their actual, finalized Aadhaar number. Using the Enrolment ID is no longer sufficient for late-stage linking.

Step-by-Step Guide to Link PAN with Aadhaar Online

The online linking process is divided into three distinct phases. It is highly recommended to follow these phases in chronological order to avoid making unnecessary payments or encountering system errors.

Phase 1: Checking Your Existing Linking Status

Before making any payment, you should verify whether your PAN and Aadhaar are already linked. This pre-login check is free and takes only a few moments.

Visit the official Income Tax e-Filing Portal at https://eportal.incometax.gov.in.
On the homepage, locate the Quick Links section on the left side of the screen and click on Link Aadhaar Status.
Enter your 10-character PAN and your 12-digit Aadhaar Number in the designated fields.
Click on the View Link Aadhaar Status button.
The portal will display a status message. If your cards are already linked, a confirmation message will appear, and no further action is required. If they are not linked, you must proceed to Phase 2.

Phase 2: Paying the ₹1,000 Late Fee via e-Pay Tax

Because the penalty-free deadline has passed, you must pay a flat late fee of ₹1,000 before the portal will allow you to submit a linking request. This payment must be processed as a single challan on the e-filing portal.

Navigate back to the e-Filing Portal homepage and click on Link Aadhaar under the Quick Links section.
Enter your PAN and Aadhaar Number, then click Validate.
A pop-up window will appear, notifying you that payment is required. Click on the Continue to Pay Through e-Pay Tax button.
Enter your PAN, re-enter it to confirm, and provide any valid mobile number to receive a verification OTP. Click Continue.
Enter the 6-digit OTP received on your mobile phone and click Validate/Continue.
You will be redirected to the e-Pay Tax page. Locate the Income Tax tile and click Proceed.
Select the relevant Assessment Year. You must select the current active Assessment Year dynamically prompted on the portal for the current financial cycle (for example, AY 2026-27). Do not select outdated assessment years.
Select the Type of Payment (Minor Head) as Other Receipts (500).
Choose the sub-type of payment as Fee for delay in linking PAN with Aadhaar, then click Continue.
The fee of ₹1,000 will be pre-filled automatically under the “Others” column. Verify this amount and click Continue.
Select your preferred payment method from the available options, which include Net Banking, Debit Card, Credit Card, RTGS/NEFT, UPI, or Payment Gateway. Complete the transaction.
Once the payment is successful, download the payment receipt/challan for your records.

Phase 3: Submitting the Final Linking Request

Important Note: The payment details do not always sync instantly with the tax database. If the system does not recognize your payment immediately, you must wait 4 to 5 working days for the payment details to reflect on the e-filing portal before proceeding with this final phase.

Once the payment has synced, return to the official e-Filing homepage and click on Link Aadhaar under Quick Links.
Enter your PAN and Aadhaar Number, then click Validate.
The portal will display a message confirming that your payment details have been verified. Click Continue.
Enter your Name exactly as it is spelled on your Aadhaar Card, along with your Aadhaar-registered mobile number.
If your Aadhaar card only displays your year of birth (and not the full date), select the checkbox “I have only year of birth in Aadhaar card”.
Select the checkbox “I agree to validate my Aadhaar details”.
Click the Link Aadhaar button.
Enter the 6-digit OTP sent to your Aadhaar-registered mobile number and click Validate to submit your request.

Alternative Channels for PAN-Aadhaar Linking

While the online e-filing portal is the most common and recommended method, the government provides alternative channels for taxpayers who may not have reliable internet access or who prefer offline assistance.

SMS-Based Linking

Taxpayers can attempt to link their cards by sending a formatted SMS from their registered mobile number. To use this method, send an SMS to either 567678 or 56161 in the following format:

UIDPAN <12-digit Aadhaar> <10-digit PAN>

Please note that if your PAN is already inoperative or requires a late fee payment, you must still complete the ₹1,000 payment online before any linking request can be successfully processed, regardless of the channel used.

Offline and Biometric-Based Linking

If you face persistent data mismatch issues or cannot complete the process online, you can visit designated PAN service centers operated by UTIITSL or Protean (formerly NSDL). At these centers, you can submit a physical, biometric-based linkage request. The service center staff will verify your identity using your fingerprints or iris scans. While this method bypasses minor typographical errors, you will be required to pay the standard ₹1,000 late fee along with a nominal service charge determined by the service center.

Key Benefits of Reactivating and Linking Your PAN

Keeping your PAN active and linked with your Aadhaar is not just a legal formality; it has direct implications for your daily financial activities. Reactivating your inoperative PAN offers several key benefits:

Restores PAN Functionality: Successfully linking the cards changes your PAN status from “inoperative” back to “operative” within a short processing window.
Enables Tax Filing: An operative PAN is mandatory for filing your Income Tax Returns (ITRs). You cannot complete your tax filing if your PAN is inactive.
Releases Held Refunds: If your PAN is inoperative, any pending tax refunds and the associated interest under Section 244A will be placed on hold under Section 139AA(2). Linking your cards ensures these refunds are released.
Avoids Higher TDS/TCS Rates: When your PAN is inoperative, tax is deducted at source (TDS) or collected at source (TCS) at much higher penalty rates. Reactivating your PAN restores standard tax rates.
Ensures KYC Compliance: An active PAN is essential for smooth Know Your Customer (KYC) compliance. It prevents the suspension of your bank accounts, trading accounts, and demat accounts.

Critical Warnings: Avoiding Scams and Double Payments

Due to the high volume of taxpayers seeking to reactivate their PANs, fraudulent schemes and technical misunderstandings are common. Protect yourself by keeping the following warnings in mind:

Beware of Phishing Scams: Do not pay the late fee through third-party links, unofficial mobile applications, or SMS links. Always navigate directly to the official Income Tax e-Filing Portal (https://www.incometax.gov.in) to make payments.
Avoid Double Payments: If your payment is successful but the portal does not reflect it immediately, do not make another payment of ₹1,000. The database sync can take 4 to 5 working days. The Income Tax Department does not issue refunds for double or accidental challan payments.
Non-Refundable Fee: The ₹1,000 late fee is strictly non-refundable. If your linking request fails due to a name or date of birth mismatch, you will not get a refund. You must correct your details first and then submit the linking request using the same paid challan.

Frequently Asked Questions

What happens if my PAN becomes inoperative?

If your PAN becomes inoperative, you cannot file your Income Tax Returns, and any pending tax refunds will not be processed. Additionally, tax will be deducted at source (TDS) and collected at source (TCS) at higher rates, and you may face significant difficulties opening bank accounts, operating demat accounts, or executing major financial transactions.

Is the ₹1,000 fee refundable if my linking fails due to data mismatch?

No, the ₹1,000 late fee is non-refundable under any circumstances. If your linking request fails due to mismatched details, you must correct your personal information on either your PAN or Aadhaar card first. Once the details match, you can complete the linking process on the portal using the same paid challan details without paying the fee again.

Do NRIs need to pay the fee to link PAN?

Non-Resident Indians (NRIs) are exempted from the mandatory requirement to link PAN with Aadhaar. However, if an NRI’s PAN has mistakenly been marked as inoperative, they must update their residential status with their jurisdictional Income Tax officer to activate the exemption and restore their PAN to operative status.

Conclusion

Linking your PAN with Aadhaar is a critical step to ensure compliance with Indian tax laws and maintain uninterrupted access to financial services. While the late fee of ₹1,000 is mandatory for those who missed the 2023 deadline, the online process is highly secure and structured. By verifying your status, ensuring your personal details match, and using only the official government portal, you can reactivate your PAN smoothly. Take action today to avoid higher tax deductions and secure your financial transactions.
