Form 10-IEA for Business Taxpayers: Old-Regime Choice Evidence File
Reviewed by CA Nikhil Gupta · Last reviewed 20 June 2026
For taxpayers with business or professional income, regime choice is not just an ITR checkbox. Form 10-IEA can become a gatekeeper for opting out/re-entering the new regime, so the filing evidence must be preserved.
Detailed analysis
Official Form 10-IEA help states that business/profession taxpayers use the form for opt-out/re-entry decisions. The practical control is to decide regime before ITR due date, file/e-verify the form, and then ensure ITR captures acknowledgement details correctly.
Practical example
A consultant under ITR-4 wants old regime because home-loan interest and deductions reduce tax. Finance/tax preparer compares regimes, files Form 10-IEA before return filing due date, saves acknowledgement, then enters the date/acknowledgement in ITR utility where asked.
Evidence and control checklist
