e-Pay Tax Challan Correction: Wrong AY or Minor Head Fix
You paid your income tax. You generated the challan, entered the details, and completed the transaction. Weeks later, you check your Form 26AS and find that the tax credit is missing. Your money has been paid, but it has not been credited to your account. The problem is almost always the same: you picked the wrong Assessment Year, the wrong Tax Year, or the wrong Minor Head.
This is one of the most stressful, expensive, and time-consuming mistakes a taxpayer can make, because your money does not disappear. It is simply sitting in the wrong bucket. And until you correct it, your tax records will show a shortfall, your refund will be delayed, and you may even receive a demand notice for tax you have already paid.
This guide covers everything you need to know about correcting e-Pay Tax challan errors, including Assessment Year, Tax Year, Major Head, and Minor Head, along with the online self-correction facility on the e-filing portal, time limits, the TRACES exception, and the Assessing Officer route when the portal no longer helps.
Short answer: Log in at incometax.gov.in and go to Services, then Challan Correction. Assessment Year and Tax Year can be corrected within 7 days of the challan deposit date. Major Head and Minor Head can be corrected within 30 days. Only minor heads 100, 300 and 400 are covered, only challans from AY 2020-21 onwards are eligible, and each challan can be corrected only once.
The Problem: What Happens When You Pick the Wrong AY or Minor Head
When you pay income tax online through the e-Pay Tax facility on the Income Tax e-Filing portal, you generate a challan (typically ITNS 280) containing details such as the Assessment Year, Tax Category (Major Head), and Type of Payment (Minor Head). Our guide on how to pay income tax online using e-Pay Tax covers the payment flow itself.
If any of these details are incorrect:
- The tax payment will not reflect in your Form 26AS against the correct assessment year.
- Your Income Tax Return will show a lower tax credit, leading to an apparent tax demand.
- Your refund may be delayed or reduced.
- You may receive an intimation under Section 143(1) demanding additional tax for money you have already paid.
The worst part: the money is not lost. The department has received it. It just needs to be reallocated to the correct head or year.
Why This Happens
| Mistake | Typical Scenario |
|---|---|
| Wrong Assessment Year | Paying tax for FY 2025-26 but selecting AY 2026-27 instead of AY 2027-28, or the reverse. A common error during the transition from the Assessment Year system to the Tax Year system introduced under the Income Tax Act, 2025. |
| Wrong Tax Year | Under the new Act, effective 1 April 2026, tax payments are mapped to Tax Year rather than Assessment Year. Selecting the wrong Tax Year causes the credit to vanish from your records. |
| Wrong Minor Head | Selecting 100 for Advance Tax instead of 300 for Self-Assessment Tax, or the reverse. Also common: selecting 400 for Demand Payment when you intended to pay self-assessment tax. |
| Wrong Major Head | Paying under Income Tax other than Companies instead of Corporation Tax, or the reverse. |
| Wrong Challan Type | Using ITNS 281, the TDS challan, through the wrong portal. |
If you are unsure which minor head applies to a quarterly instalment, see our guide on advance tax due dates for FY 2026-27.
What You Can Correct: AY, TY, Major Head, Minor Head
The Income Tax Department provides an online challan correction facility on the e-Filing portal, allowing PAN holders to correct key challan details directly without approaching an Assessing Officer for routine corrections.
Correctable Fields
| Field | Can You Correct Online? |
|---|---|
| Assessment Year | Yes, within 7 days |
| Tax Year | Yes, within 7 days |
| Major Head, Tax Applicable | Yes, within 30 days |
| Minor Head, Type of Payment | Yes, within 30 days |
| PAN or TAN | No, requires AO route |
| Total Amount | No, requires AO route |
Important: the correction facility is available only for eligible paid and unconsumed challans, meaning challans that have not already been consumed during processing. Once the challan has been consumed by CPC in processing your return, the online correction window closes and you must approach your Assessing Officer.
Eligible Challans
The service covers challans relating to Assessment Year 2020-21 onwards. For earlier years, taxpayers must approach their Jurisdictional Assessing Officer.
The Department also states that a challan correction request can be submitted only once through the portal. Any further corrections require intervention from the Assessing Officer.
The 7-Day and 30-Day Windows: Know Your Deadlines
The portal allows different correction windows depending on the type of mistake.
Corrections Allowed Within 7 Days
| Correction Type | Time Limit |
|---|---|
| Tax Year | 7 days from challan deposit date or CIN generation date |
| Assessment Year | 7 days from challan deposit date or CIN generation date |
The seven-day limit is counted from the challan deposit date or CIN generation date.
Corrections Allowed Within 30 Days
| Correction Type | Time Limit |
|---|---|
| Major Head, Tax Applicable | 30 days from challan deposit date |
| Minor Head, Type of Payment | 30 days from challan deposit date |
Minor Head correction is available only for:
- 100, Advance Tax
- 300, Self-Assessment Tax
- 400, Demand Payment as Regular Assessment Tax
For other Minor Head categories, taxpayers must approach the Jurisdictional Assessing Officer.
What Happens If You Miss the Window
If the 7-day or 30-day window has passed:
- The online self-correction facility will not allow the correction.
- The challan is treated as consumed or locked.
- Your only route is to approach the Jurisdictional Assessing Officer with a written request and supporting documents.

Process for TDS Challans, ITNS 281
TDS challans cannot be corrected through the e-Filing portal.
The department's user manual states that correction of ITNS 281 challans, used for TDS and TCS payments through a TAN, is available through the TRACES portal and not through the e-Filing portal.
For TDS challan corrections:
- Visit the TRACES portal at tdscpc.gov.in.
- Log in using your TAN credentials.
- Go to Request for OLTAS Correction under the Statement Payment tab.
- Select the correction type: Assessment Year, Major Head, Minor Head, or TAN.
- Submit the correction request.
Note: several tax professionals and media reports have flagged concerns that taxpayers who accidentally deposit TDS challans under the wrong financial year may face difficulties correcting those entries online. Certain financial-year correction functionalities are either limited or not fully supported on the newer TRACES interface, forcing users to rely on legacy correction mechanisms or jurisdictional officers. Our guide on TDS return correction and revision on TRACES covers the statement-level corrections that often accompany a challan fix.
The AO Route: What to Do When the Portal Window Has Closed
If the 7-day or 30-day window has passed, or if the challan has already been consumed by CPC processing, your only option is to approach the Jurisdictional Assessing Officer with a written request.
When the AO Route Is Required
| Scenario | Action Required |
|---|---|
| Challan already consumed in CPC processing | Manual correction via AO |
| Second correction attempt | AO route only, the portal allows one correction |
| Correction for AY before 2020-21 | Approach Jurisdictional AO |
| Minor Head correction other than 100, 300 or 400 | Approach Jurisdictional AO |
| Correction of PAN, TAN or Amount | Approach Jurisdictional AO |
| TDS challan on wrong financial year | TRACES portal or AO route |
How to Request Correction via AO
-
Prepare a written representation clearly stating:
- The error made, such as wrong Assessment Year or Minor Head
- The correct details
- Challan details: CIN, date, amount, bank branch
- A copy of the challan, downloadable from your e-Pay Tax payment history
-
Submit the request to your Jurisdictional Assessing Officer along with supporting documents.
-
Follow up until the correction is processed.
Warning: the AO route is slower and less predictable than the online facility. The officer may need to manually enter the data in the correction request and submit it for approval of the relevant authority.
The 2026 Transition: AY vs TY and the New Challan Form
Under the Income Tax Act, 2025, effective 1 April 2026, Tax Year 2026-27, the tax payment and challan system has been updated:
| Old System | New System |
|---|---|
| Assessment Year | Tax Year |
| Challan form: ITNS 280 | Challan form: ITNS 280N |
The new ITNS 280N challan form is for payment of various types of income tax under the Income Tax Act, 2025. Our Income Tax Act 2025 section mapping guide sets out how the old and new numbering line up.
This is where many errors originate. Taxpayers are not sure whether to select Assessment Year or Tax Year when paying tax in the transition period. The rule is:
- For income earned in FY 2025-26, select AY 2026-27.
- For income earned in TY 2026-27 onwards, select Tax Year.
A wrong selection will cause your tax credit to vanish, and the correction window for Assessment Year or Tax Year is only 7 days.

Common Questions About Challan Correction
Q: Can I correct a wrong Assessment Year after filing my ITR?
A: If the challan has already been consumed by CPC processing, the online correction window is closed. You must approach your Jurisdictional Assessing Officer with a written request and supporting documents.
Q: What is the difference between Major Head and Minor Head?
A: Major Head is the category of tax, either Income Tax or Corporation Tax. Minor Head is the type of payment: Advance Tax at 100, Self-Assessment Tax at 300, or Demand Payment at 400.
Q: I paid a TDS challan under the wrong financial year. Can I correct it online?
A: For TDS challans, ITNS 281, correction must be done through the TRACES portal, not the e-Filing portal. Certain financial-year correction functionalities may be limited, forcing you to rely on legacy correction mechanisms or jurisdictional officers.
Q: How many times can I correct a challan?
A: The Income Tax Department allows a challan correction request to be submitted only once through the portal. Any further corrections require intervention from the Assessing Officer.
Q: What if I miss the 7-day window for correcting Assessment Year?
A: You must approach your Jurisdictional Assessing Officer. The online self-correction facility will not allow the correction after the window closes.
Q: Does the new Income Tax Act 2025 change the challan correction rules?
A: Yes. The new Act introduces the Tax Year concept alongside Assessment Year, and a new challan form, ITNS 280N, has been introduced for payments under the new Act.
Q: My challan is correct but the credit still is not showing. What now?
A: Check whether the issue is a challan error at all. If tax was deducted at source rather than self-paid, the problem may be a TDS reporting failure instead. See TDS not showing in Form 26AS and AIS vs Form 26AS vs TIS to identify which statement is wrong before filing a correction.
