India’s income-tax system is built around individual taxation, with separate exemption limits and deductions for each taxpayer. Marriage does not change this treatment, and spouses continue to file and pay taxes independently, even though most households function with shared incomes, expenses, and financial priorities.

Ahead of Union Budget 2026, this approach is drawing renewed scrutiny from tax experts. Many argue that the current system does not reflect modern household economics, as it fails to recognise married couples as a single financial unit where incomes and spending are closely linked.

If optional joint tax filing is introduced, the measure could help reduce the overall tax outgo for many households, particularly those dependent on a single income. The idea, which has been put forward by the Institute of Chartered Accountants of India (ICAI), is already followed in countries such as the US and Germany, where joint filing for married couples is an established practice.

Under the proposed framework, the combined income of a household would be assessed under a distinct tax slab system. This could lower the tax liability for families where one spouse earns significantly more than the other. Joint filing could also allow couples to make more effective use of deductions on home loans, health insurance premiums, and other eligible tax-saving investments.

What did ICAI say in the proposal?

Married couples with valid PANs for both spouses would be allowed to file a joint return and choose to be taxed together. Taxpayers would continue to have the flexibility to remain under the existing individual taxation system if they prefer.

ICAI has recommended that the basic exemption limit under joint taxation be doubled, with tax slabs expanded in line with combined household income. In the structure outlined by the institute, income up to Rs 8 lakh would not attract tax, while higher slabs would apply progressively, with the top rate of 30 percent kicking in for income above Rs 48 lakh.

How joint taxation benefits?

Under the current system, a non-earning spouse’s basic exemption limit and lower tax slabs remain unused. A joint filing regime would unlock this idle capacity, enabling income averaging, thereby lowering the overall tax incidence on the family. “Joint filing encourages cohesive household financial planning, simplifies investment structuring, and aligns neatly with the government’s vision of a new tax regime with minimal deductions and cleaner slab-based taxation,” said Priyal Goel Jain, CA, partner NRI tax expert, Dinesh Aarjav & Associates.

“Retired couples, in particular, would benefit from smoother taxation of pension and investment income, reducing the need for complex tax arbitrage. Over time, this could also lead to lower tax evasion and reduced litigation, as incentives for artificial income-splitting diminish,” Jain said.

However, joint filing may not always be tax effective, especially when both spouses high income earners. It can push the combined income in higher tax rate or higher surcharge bracket.

Parliament's budget session begins January 28 and will continue until April 2. Finance Minister Nirmala Sitharaman will present the Budget for the financial year 2026–27 on February 1.
