Introduction

The new tax regime is now the default tax regime. This means that if a taxpayer does not actively opt for the old tax regime, tax may be calculated under the new regime.

However, taxpayers having business or professional income cannot switch freely between regimes every year like normal salaried taxpayers.

If they want to switch from the new tax regime to the old tax regime, they need to file Form 10-IEA within the due date.

This article explains:

  • who needs Form 10-IEA;
  • who does not need Form 10-IEA;
  • how many times it can be filed;
  • how to file it online;
  • what details are needed in ITR-3 or ITR-4;
  • common mistakes to avoid.

What Is Form 10-IEA?

Form 10-IEA is used by taxpayers having business or professional income to:

  • opt out of the new tax regime and choose the old tax regime; or
  • re-enter the new tax regime after previously opting for the old regime.

In simple words, Form 10-IEA is required when a business/professional income taxpayer wants to formally choose or change tax regime.

Why Form 10-IEA Is Important

The old tax regime allows many deductions and exemptions, such as:

  • Section 80C deduction;
  • Section 80D deduction;
  • HRA exemption;
  • home loan interest deduction;
  • NPS additional deduction;
  • certain allowances and exemptions.

The new regime offers lower slab rates but does not allow many old-regime deductions.

Therefore, taxpayers with deductions may prefer the old regime. But if they have business or professional income, they must file Form 10-IEA within time.

Who Needs to File Form 10-IEA?

Form 10-IEA is required where the taxpayer has income from business or profession and wants to choose the old regime.

Taxpayer TypeForm 10-IEA Required?
Individual with business incomeYes, if opting for old regime
Individual with professional incomeYes, if opting for old regime
FreelancerYes, if opting for old regime
F&O trader reporting business incomeYes, if opting for old regime
Intraday trader reporting business/speculative incomeYes, if opting for old regime
ITR-3 filer with business/professional incomeYes, if opting for old regime
ITR-4 filer with presumptive incomeYes, if opting for old regime
HUF with business/professional incomeYes, if opting for old regime

Who Does Not Need Form 10-IEA?

Form 10-IEA is generally not required where the taxpayer does not have business or professional income.

Income TypeForm 10-IEA Required?
Salary income onlyNo
Pension income onlyNo
Salary + bank interestNo
Salary + rental incomeNo
Salary + capital gainsNo
Pension + interest incomeNo
ITR-1 filerNo
ITR-2 filer without business/professional incomeNo

Such taxpayers can select old or new regime directly in the ITR, subject to the applicable due date.

ITR-1 / ITR-2 vs ITR-3 / ITR-4

ITR FormTypical UseForm 10-IEA Requirement
ITR-1Salary/pension/interest/simple incomeUsually not required
ITR-2Salary, capital gains, foreign assets, etc., without business incomeUsually not required
ITR-3Business/professional income, F&O, intraday, complex incomeRequired if opting for old regime
ITR-4Presumptive business/professional incomeRequired if opting for old regime

The key test is not only the ITR form. The key test is whether you have income under the head Profits and Gains from Business or Profession.

Is Form 10-IEA Required for F&O and Intraday Traders?

Yes, if F&O or intraday income is reported as business/professional income and the taxpayer wants to opt for the old regime.

For example:

CaseForm 10-IEA Required?
Salaried person with F&O income filing ITR-3 and choosing old regimeYes
Salaried person with intraday trading income filing ITR-3 and choosing old regimeYes
Freelancer filing ITR-3 and choosing old regimeYes
Presumptive taxpayer filing ITR-4 and choosing old regimeYes
Pure salaried person filing ITR-1 and choosing old regimeNo

How Many Times Can Form 10-IEA Be Filed?

For taxpayers having business or professional income, Form 10-IEA has a major limitation.

It can generally be used:

ActionMeaning
First timeOpt out of new regime and choose old regime
Second timeRe-enter the new regime
After re-entering new regimeCannot go back to old regime again while business/professional income continues

This is why Form 10-IEA should not be filed casually.

Once a business/professional taxpayer opts out of the new regime and later re-enters the new regime, they generally cannot opt for the old regime again unless they cease to have business/professional income.

Is Form 10-IEA Required Every Year?

No.

If you have business/professional income and already filed Form 10-IEA in an earlier year to opt for the old regime, you do not need to file Form 10-IEA again every year to continue the old regime.

However, while filing ITR, you may need to enter the earlier Form 10-IEA details, such as:

  • assessment year;
  • date of filing;
  • acknowledgement number.

Due Date for Filing Form 10-IEA

Form 10-IEA must be filed on or before the due date of filing the return under Section 139(1).

For AY 2026-27, check the applicable due date carefully on the portal based on your ITR category and audit requirement.

For many ITR-3/ITR-4 non-audit business/professional cases, the due date may differ from simple salaried cases. Therefore, do not assume one common due date for all taxpayers.

What Happens If Form 10-IEA Is Filed Late?

If Form 10-IEA is filed after the due date, it may be treated as invalid.

If the form is invalid, the old regime benefit may not be available.

SituationResult
Form 10-IEA filed within due dateOld regime may be validly selected
Form 10-IEA filed after due dateForm may become invalid
ITR filed under old regime without valid Form 10-IEAOld regime benefit may be denied
Belated ITR filed without timely Form 10-IEANew regime may apply by default

Therefore, business/professional taxpayers should file Form 10-IEA before filing ITR and within the due date.

Can Form 10-IEA Be Revised?

No.

Form 10-IEA cannot be revised or modified after submission. Also, once it is filed, it cannot be withdrawn in the same year.

This means taxpayers should compare both regimes before filing the form.

Which Act Tab Should Be Selected for AY 2026-27?

For AY 2026-27, the return relates to FY 2025-26. It is governed by the Income-tax Act, 1961.

Therefore, while filing Form 10-IEA for AY 2026-27, taxpayers may need to select the forms under the Income-tax Act, 1961 section of the portal, not the Income-tax Act, 2025 tab.

This distinction is important because AY 2026-27 relates to the old Act, while Tax Year 2026-27 relates to the new Act.

How to Check Form 10-IEA Status

After filing Form 10-IEA, check status on the portal.

Path:

e-File → Income Tax Forms → View Filed Forms → Search Form 10-IEA

Check whether the form status is:

StatusMeaning
Valid FormAccepted for use
Invalid FormMay not be accepted, often due to late filing or wrong due date
SubmittedFiled but check processing/status
Pending verificationComplete e-verification

Do not assume that filing alone is enough. Check the status before filing ITR.

What If Form 10-IEA Becomes Invalid?

If the form becomes invalid, the old tax regime may not be allowed for that year.

Possible reasons include:

  • form filed after due date;
  • wrong due date selected;
  • ITR filed late;
  • mismatch in ITR details;
  • incorrect assessment year;
  • portal validation issue.

In such cases, the taxpayer may have to file under the new regime for that year and may file afresh in a subsequent assessment year, subject to law.

TaxClear View

Form 10-IEA is simple in appearance but important in tax planning.

For a salaried person without business income, the tax regime can be selected directly in ITR. But for business/professional income taxpayers, Form 10-IEA controls access to the old regime.

Therefore, do not file Form 10-IEA blindly.

First compare both regimes. Then decide whether old regime actually saves tax. If it does, file Form 10-IEA before due date, save the acknowledgement, and enter details correctly in ITR.

Conclusion

Form 10-IEA is mandatory for many taxpayers having business or professional income who want to choose the old tax regime.

If you file ITR-3 or ITR-4 and want old-regime deductions, do not wait until the last moment. File Form 10-IEA before the applicable due date, verify it, save the acknowledgement and enter the details correctly in your ITR.

For taxpayers without business or professional income, Form 10-IEA is generally not required. They can usually select their tax regime directly in ITR.
