Taxpayers with business or professional income face stricter rules than salaried individuals when choosing between old and new tax regimes for the 2026-27 filing season. With the ITR filing period now open, understanding the five-year lock-in rule and the implications of Form 10-IEA is essential to avoid potential tax traps.
What Happened
As the Income Tax Return (ITR) filing season for the financial year 2025-26 (Assessment Year 2026-27) begins, taxpayers are again weighing the benefits of the old tax regime against the default new tax regime. While salaried employees often have the flexibility to switch between these systems each year, individuals earning income from a business or profession—specifically those using the presumptive taxation scheme—face a much more rigid set of rules.
Taxpayers who rely on Section 44AD (for small businesses) or Section 44ADA (for professionals and freelancers) to simplify their tax filings must be careful before finalizing their choice. Unlike their salaried counterparts, their decision involves long-term commitments that can limit future tax planning flexibility.
The Five-Year Lock-In Risk
The most critical aspect for those under the presumptive taxation scheme is the continuity requirement. The Income-Tax Act generally expects taxpayers who opt for this scheme to remain within it for five consecutive years. If a taxpayer chooses to exit this scheme, they face a restriction: they are ineligible to re-enter it for the next five subsequent years.
For an entrepreneur or professional, this means that moving away from the presumptive scheme to a standard audit-based filing system is not a decision to be taken lightly. Once you move out, you cannot simply return to the presumptive route the following year if you find the compliance burden or tax liability of the standard audit method is higher than expected.
The Complexity Of Switching Regimes
Presumptive taxpayers also have a complex journey when choosing between the old and new tax regimes. While the law allows business owners and professionals to opt out of the default new tax regime, this process requires filing a specific declaration, Form 10-IEA.
This choice is not just a one-time toggle. For individuals with business or professional income, opting out of the new tax regime can be effectively irreversible in the context of their business income. If a freelancer or small business owner decides to opt out of the new regime to claim deductions under the old regime, they cannot easily switch back for their business income in future years. This rigidity makes the initial evaluation of tax savings—comparing potential deductions against the lower slab rates of the new regime—vital.
Why The Distinction Matters
Many taxpayers, especially those involved in stock market trading or independent consulting, often assume that tax regime flexibility applies universally. However, the regulatory framework treats business income differently to ensure consistency in tax reporting. For those filing through ITR-3, ITR-4, or ITR-5, the system requires careful planning because the tax department views business income as a continuous stream, unlike the salary income of an employee.
What To Monitor Next
Before filing your ITR, compare your projected tax liability under both the old and new regimes, accounting for potential deductions you might lose or gain. If you are currently in the presumptive scheme, check your history to ensure you are not inadvertently triggering an exit that could lock you out for five years. For those planning to use Form 10-IEA to opt out of the new regime, ensure the form is filed within the due date to avoid invalidation of your tax return. When in doubt, reviewing your specific financial situation with a tax professional is the safest path to avoid future compliance issues.
