Married couples in India can independently choose either the new or old tax regime when filing their income tax returns [1].
This flexibility allows spouses to optimize their individual tax liabilities based on their specific investments and income levels. Because Indian tax law treats each person as a separate taxpayer, a husband and wife are not required to follow the same filing system [2].
For the financial year 2025-26 [1], taxpayers must decide which regime offers the most benefit before the filing deadline in 2026 [2]. The new tax regime typically offers lower slab rates but removes many exemptions. Conversely, the old tax regime allows taxpayers to claim various deductions, such as those for insurance or home loans [3].
Tax experts said that this independence is a fundamental aspect of the Indian tax code. A spouse who has significant tax-saving investments may find the old regime more advantageous, while a spouse with fewer deductions may prefer the new regime's lower rates [2].
Employers may sometimes select the new tax regime by default for their employees. However, individuals maintain the right to switch to the old regime during the filing process to claim eligible deductions [3]. This ensures that the final tax liability is determined by the taxpayer rather than the employer's administrative default [3].
Under this legal framework, the choice of one spouse has no bearing on the legal options available to the other. This separation ensures that diverse financial portfolios within a single household can be managed according to the most efficient tax strategy [2].
“Each individual is treated as a separate taxpayer under Indian tax law.”
The ability for spouses to diverge in their tax regime choices highlights the individualistic nature of India's income tax system. By decoupling marital status from tax filing methods, the law prevents a 'lowest common denominator' effect where one spouse's lack of investments would force the other to abandon beneficial deductions.
