Form 10-IEA for Business and Profession Taxpayers: Old Regime Choice Checklist
Reviewed by CA Nikhil Gupta · Last reviewed 19 June 2026
For FY 2025–26 / AY 2026–27, business/profession taxpayers continue to use the Income-tax Act, 1961 regime-choice framework and Form 10-IEA where required. For income from 1 April 2026, do not reuse Form 10-IEA: under Rule 136 of the Income-tax Rules, 2026 the Section 202 option is exercised or withdrawn in the return of income furnished under Section 263(1), with no separate form.
What Form 10-IEA does
The official Form 10-IEA manual says that for business cases, Form 10-IEA is used by taxpayers to exercise the right to choose between old and new tax regime. It also says the form can be filed twice in lifetime: once to opt out of the new regime and once to re-enter it.
For the connected rule or filing step, see Form 10-IEA: Old Regime Option for Business or Professional Income.
Who should review it
| Taxpayer profile | Why it matters |
|---|---|
| Freelancer or consultant reporting business/profession income | Regime choice may need Form 10-IEA by due date. |
| Small trader under presumptive taxation | Check ITR-4 and Form 10-IEA flow before filing. |
| Salaried person with side business | Business/profession income can change annual flexibility. |
| Partner/professional with deductions | Old regime may matter, but form timing must be respected. |
Checklist before filing
- Confirm whether return includes business/profession income.
- Compare tax under old and new regime using actual deductions.
- Check due date under Section 139(1).
- File Form 10-IEA before return filing where required.
- Save acknowledgement with ITR working papers.

Decision table
| Situation | 2026 treatment / control | Why it matters |
|---|---|---|
| FY 2025–26 / AY 2026–27 | Use the 1961 Act regime-choice framework and Form 10-IEA where required. | This is still an assessment year under the old Act. |
| Tax year 2026–27 beginning 1 Apr 2026 | Use Income-tax Act, 2025 section 202 option mechanics and current prescribed form/return. | Do not assume old Form 10-IEA remains the operative form. |
| Business/profession taxpayer | Switching flexibility is restricted compared with non-business taxpayers. | Preserve election acknowledgements. |
| No business income | Annual return choice can operate differently. | Do not file business-election forms unnecessarily. |
Worked practical example
A consultant filing the return for FY 2025–26 (AY 2026–27) may need Form 10-IEA to use the old regime. That is a different year from income earned from 1 April 2026; for that tax year, verify the 2025 Act option and prescribed 2026 form instead of reusing last year’s filing habit.
