PAN-Aadhaar Link & ITR Processing

TL;DR

PAN must be linked to Aadhaar to file an income-tax return (with a few exceptions).

Three steps decide the speed of your ITR processing: PAN-Aadhaar linking, e-verification of the return, and matching the data in your 26AS / AIS. Miss any one of these and your return will not be processed — you will face a defect notice under Section 139(9) or a delayed refund. This post walks through each step.

Step 1 — PAN-Aadhaar Linking

Under Section 139AA(2) of the Income-tax Act, every person who has been allotted a PAN and is also an Indian citizen must link their PAN with Aadhaar. The link is a one-time exercise. Once linked, the PAN remains linked for life.

Who must link

• Indian citizens holding a PAN.
• Resident individuals (citizen of India).

Who is exempt

• Non-resident Indians (NRIs) — under the original rule. A 2023 amendment tightened this; check the latest notification.
• Individuals above 80 years of age.
• Individuals resident in the States / UTs of Assam, Jammu & Kashmir, Ladakh, Meghalaya — though this exemption has been narrowed by subsequent notifications.

If you fall in the exempt category, you must file a declaration on the e-filing portal.

The Linking Process

1. Go to incometax.gov.in.
2. Login to the e-filing portal with your PAN as user ID.
3. Go to Profile Settings → Link Aadhaar.
4. Enter your Aadhaar number, name as on Aadhaar.
5. Receive the OTP on the mobile number linked to your Aadhaar.
6. Submit.
7. Receive the Aadhaar OTP (if consent for sharing is given) — this completes the e-KYC.
8. The linking confirmation is shown in 24–48 hours.

If the Linking Fails

The most common reason for failure is a name mismatch between PAN and Aadhaar. The PAN database has your name as per the PAN application; the Aadhaar database has your name as per the Aadhaar application. If the two names differ — say, “Rahul Kumar Sharma” on PAN vs “Rahul Sharma” on Aadhaar — the link fails.

The fix is to update either PAN or Aadhaar to match the other:

• Update PAN: Use the PAN change request form at any UTI / NSDL centre. The update takes 7–15 days.
• Update Aadhaar: Use the UIDAI self-service portal at myaadhaar.uidai.gov.in for online update, or visit an enrolment centre for offline update. The update takes 7–10 days for online, 30 days for offline.

The Fee

Linking is free of cost if done on the e-filing portal. If you link through a PAN service centre, the centre may charge a service fee (typically ₹50–100). A late-fee of ₹1,000 is levied if the link is done after the due date notified for that financial year — historically, the CBDT has extended the deadline multiple times, but a ₹1,000 fee applies once the deadline passes.

What Happens if You Don’t Link

Under Section 139AA(3), if the PAN-Aadhaar link is not completed by the notified date, the PAN becomes inoperative. The consequences of an inoperative PAN are significant:

• All pending refunds will be withheld.
• TDS will continue to be deducted at the higher rates under Section 206AA (20%).
• The PAN cannot be used as a valid identity document.
• The taxpayer cannot file a return using the PAN.

To reactivate an inoperative PAN, the taxpayer must pay the fee (if applicable), complete the link, and update KYC details. The reactivation takes 15–30 days.

Step 2 — E-Verification of the Return

After filing the ITR, the taxpayer must verify the return within 30 days of filing. The verification is electronic (e-verification) — no physical signature is required.

The Three Methods

1. Aadhaar OTP (Most Common)

• Login to the e-filing portal.
• Open the filed return.
• Click e-Verify → Aadhaar OTP.
• Receive the OTP on the mobile number linked to Aadhaar.
• Enter the OTP. Verification is complete.

The OTP is valid for 15 minutes. If expired, request a new OTP.

The e-verification using Aadhaar OTP does not require the OTP from the bank’s net-banking or DSC. It is the fastest method for individuals.

2. Net-Banking

• Login to the e-filing portal.
• Open the filed return.
• Click e-Verify → Net Banking.
• Choose the bank through which you have an e-filing-enabled net-banking account (most major banks are enabled).
• Login to the bank’s portal.
• Authorise the e-verification.

The bank’s authorisation logs the e-verification instantly.

3. DSC (Digital Signature Certificate)

• Login to the e-filing portal.
• Open the filed return.
• Click e-Verify → DSC.
• Plug in the DSC token.
• Sign with the DSC.

The DSC method is used by businesses and in cases where the Aadhaar OTP is not available (e.g., mobile number changed).

What if You Miss the 30-Day Window

If e-verification is not completed within 30 days, the return is treated as not filed. The taxpayer is treated as a defaulter under Section 276CC (criminal prosecution for failure to furnish return — imprisonment from 3 months up to 2 years, and fine; where the tax evaded exceeds ₹25 lakh, imprisonment can extend up to 7 years). The refund (if any) is not processed. The deadline can be extended by filing a condonation request — but the request is rarely granted unless there is a genuine cause.

The practical fix: file a fresh return, e-verify within 30 days. The fresh return replaces the unverified one.

Step 3 — ITR Processing

After e-verification, the return is processed by the Centralised Processing Centre (CPC) in Bengaluru. The processing typically completes in 20–30 days for clean returns, and can take 60–90 days for returns with mismatches.

What the Processor Checks

The CPC’s automated system compares the data in the ITR against:

• Form 26AS — the TDS statement issued by the deductor.
• Annual Information Statement (AIS) — the comprehensive statement of all financial transactions reported to the income-tax department (bank interest, dividends, property transactions, share transactions, mutual fund transactions, etc.).
• Form 16 — the TDS certificate from the employer.
• Other ITRs — if you filed a return with the same PAN in earlier years, the year-on-year numbers are compared.
• Tax payment challans — if you paid advance tax or self-assessment tax, the challan is matched.

Common Processing Outcomes

1. Refund issued

The tax paid (TDS + advance tax + self-assessment tax) exceeds the tax on total income. The refund is processed through the Electronic Clearing Service (ECS) to the bank account validated in the ITR. The refund is typically credited within 7–15 days of the intimation under Section 143(1).

2. Demand raised

The tax paid is less than the tax on total income. The CPC issues a demand notice under Section 143(1). The taxpayer must pay the demand within 30 days, or file a response.

The demand can be contested under Section 154 (rectification) or Section 264 (revision by the Principal Commissioner). The demand is also appealable under Section 246A to the CIT(A) within 30 days.

3. Adjustment under Section 143(1)(a)

The CPC adjusts the returned income for specific errors — non-disclosure of interest, AIS mismatch, TDS credit mismatch. The intimation under Section 143(1) is sent. If the adjustment is in your favour, a refund is processed. If the adjustment is against you, a demand is raised.

What Triggers an Adjustment

• TDS credit in 26AS is more than TDS claimed in ITR — the credit is added, refund is increased.
• TDS credit in 26AS is less than TDS claimed in ITR — the credit is removed, demand is raised.
• Interest income in AIS not in ITR — added to income, demand raised.
• Dividend income in AIS not in ITR — added, demand raised.
• Share transaction in AIS not in ITR — typically a soft flag, but for STCG / LTCG, it triggers a demand.
• Property transaction in AIS not in ITR — added, demand raised.
• Bank deposit interest in AIS not in ITR — added, demand raised.

The Defective Return Notice

If the data does not reconcile, the CPC issues a defective return notice under Section 139(9). The taxpayer must respond within 15 days (or the extended period). The response is to file a corrected return in the e-filing portal.

The most common defects:

• Wrong ITR form (see our ITR form guide).
• Income omitted from the return.
• Deduction claimed without valid proof.
• Bank account details not validated.
• PAN not linked to Aadhaar.

Practical Workflow

For an individual with simple income (salary + one house + interest):

1. Download Form 16 from the employer.
2. Download Form 26AS and AIS from the e-filing portal.
3. Match Form 16 / 26AS / AIS to your income records.
4. Link PAN-Aadhaar if not done.
5. File ITR-1 using the ITR utility or the e-filing portal’s online form.
6. E-verify using Aadhaar OTP.
7. Wait 20–30 days for processing.
8. Receive intimation under Section 143(1).
9. Receive refund (if any) in 7–15 days.

For a taxpayer with business income, capital gains, or foreign income:

1. Pull all AIS, 26AS, Form 16, broker statements, bank statements.
2. Prepare the books of accounts.
3. Compute the taxable income.
4. Choose the ITR form (ITR-2, ITR-3, ITR-4).
5. File the return.
6. E-verify.
7. Track processing on the e-filing portal.
