ITR Filing FY 2025-26: Rules for Switching Between Old and New Tax Regimes Explained

As taxpayers prepare to file Income Tax Returns (ITRs) for Financial Year 2025-26, selecting the appropriate tax regime continues to be an important tax-planning decision. The suitability of the old or new tax regime may vary depending on an individual's financial commitments, deductions, exemptions, and sources of income during a particular year.

The Income-tax Act currently treats the new tax regime as the default tax regime for individual taxpayers. However, eligible taxpayers can choose to be taxed under the old regime, subject to specified conditions.

Switching Between Tax Regimes

The ability to move between the old and new tax regimes depends primarily on whether the taxpayer has income from a business or profession.

Individuals Without Business or Professional Income

Taxpayers earning income from salary, pension, house property, capital gains, or other non-business sources generally have the flexibility to choose between the old and new tax regimes each financial year while filing their income tax return. This allows them to evaluate which regime offers greater tax efficiency based on their prevailing deductions and exemptions.

Individuals With Business or Professional Income

For taxpayers having income from a business or profession, the rules are more restrictive. Once such taxpayers opt out of the default new tax regime and choose the old tax regime, that choice becomes applicable for subsequent years.

The Income-tax Act provides an option to withdraw the earlier selection and return to the new tax regime. However, this withdrawal facility can generally be exercised only once, after which the taxpayer may not be able to switch back and forth annually.

Factors Affecting Regime Selection

The comparative benefit of each tax regime may change over time due to factors such as:

• Availability of deductions under Section 80C and other provisions
• Home loan interest benefits
• Housing loan repayment status
• Investment patterns
• Changes in salary structure
• Eligibility for exemptions and tax-saving deductions

As a result, taxpayers should review their financial position each year before deciding on the most suitable tax regime.

Compliance Consideration

Taxpayers should carefully assess their income profile and applicable tax provisions before exercising a regime choice during ITR filing. Those having business or professional income should pay particular attention to the restrictions on switching, as the decision may have implications for future assessment years.
