ITR Filing FY 2025-26: Can You Switch Tax Regimes Every Year?

As the financial year progresses, taxpayers face the critical decision of choosing between the old and new income tax regimes to maximize savings. While your financial life changes annually—due to home loans, investments, or shifting income levels—the ability to switch regimes is not universal.

The Core Distinction: Salary Earners vs. Business Professionals

The flexibility to switch between the old and new tax regimes depends entirely on the nature of your income source. For individuals who do not have business or professional income (such as salaried employees), the rules offer significant freedom. These taxpayers can evaluate their deductions, such as Section 80C or home loan interest, and choose the most beneficial regime every single year.

However, the rules change drastically for those with business or professional income. For this group, opting for the old tax regime is a binding decision for subsequent years. While there is a provision to withdraw this option, it can only be exercised once. This restriction exists because business taxation involves complex, multi-year factors like depreciation and the carrying forward of losses, which require long-term consistency.

Why the Government Restricts Switching for Businesses

The distinction in policy is a strategic move by the tax authorities to ensure certainty. According to Richa Sawhney, Partner Tax at Grant Thornton Bharat LLP, the tighter framework for business owners is intended to discourage frequent switching just to exploit year-specific tax advantages.

For a professional or entrepreneur, the tax position is rarely confined to a single year. Factors like business expenses and losses have continuing implications across financial cycles. Therefore, for business taxpayers, choosing a regime is a long-term strategic decision rather than a simple annual calculation.

Crucial Deadlines and Compliance Rules

When planning your ITR filing for FY 2025-26 (to be filed by July 31, 2026), keep these technicalities in mind:

• The Default Regime: The new tax regime is currently the default option. If you wish to use the old regime to claim exemptions, you must actively opt for it.
• The July 31 Deadline: To benefit from the old tax regime, you must file your return within the prescribed deadline of July 31, 2026.
• The Risk of Belated Returns: If you miss the deadline and file a belated tax return, you will automatically be moved to the new tax regime, potentially losing out on significant deductions.
• Section 115BAC: Note that Section 115BAC provisions will apply to the upcoming returns for FY 2025-26.

Key Takeaways

• Salaried individuals enjoy the flexibility to switch between the old and new tax regimes every year based on their evolving financial needs.
• Business and professional income earners face much stricter rules, as choosing the old regime is largely a binding, long-term decision.
• Timely filing is mandatory; missing the July 31 deadline results in an automatic shift to the new tax regime, regardless of your preference.
