The Institute of Chartered Accountants of India (ICAI) has proposed introducing optional joint tax filing for married couples in India, potentially transforming how households manage their tax obligations. The proposal comes ahead of Union Budget 2026-27, which Finance Minister Nirmala Sitharaman will present on February 1, 2026.

Currently, India's income-tax system operates on individual taxation principles, with separate exemption limits and deductions for each taxpayer. Marriage does not alter this treatment, requiring spouses to file and pay taxes independently despite most households functioning with shared incomes and financial priorities.

ICAI's Joint Filing Framework

The proposed system would allow married couples with valid PANs for both spouses to file joint returns and choose combined taxation. Taxpayers would retain flexibility to continue under the existing individual taxation system if preferred.

Under ICAI's framework, the basic exemption limit would be doubled for joint filers, with tax slabs expanded proportionally to accommodate combined household income. The structure ensures income up to ₹8.00 lakh remains tax-free, while the top rate of 30% applies to combined income exceeding ₹48.00 lakh.

Benefits for Single-Income Families

The joint filing system primarily benefits households where one spouse earns significantly more than the other. Under current rules, a non-earning spouse's basic exemption limit and lower tax slabs remain unutilized. Joint filing would unlock this capacity through income averaging, potentially reducing overall family tax liability.

Couples could also maximize deductions on home loans, health insurance premiums, and other eligible tax-saving investments more effectively. The system encourages cohesive household financial planning and simplifies investment structuring, according to tax experts.

Expert Perspectives and Limitations

Priyal Goel Jain, CA and partner at Dinesh Aarjav & Associates, highlights that joint filing aligns with the government's vision of a simplified tax regime with minimal deductions and cleaner slab-based taxation. Retired couples would particularly benefit from smoother taxation of pension and investment income, reducing complex tax arbitrage needs.

However, joint filing may not always prove tax-effective, especially when both spouses are high income earners. Combined income could push couples into higher tax brackets or surcharge categories, potentially increasing their overall tax burden.

Budget Timeline and Implementation

Parliament's budget session begins January 28, 2026, and continues until April 2, 2026. The proposal follows practices already established in countries like the United States and Germany, where joint filing for married couples represents standard practice. The optional nature of the proposed system ensures couples can choose the most beneficial taxation method for their specific circumstances.

The upcoming Budget 2026 is positioned to strengthen India's agriculture sector through enhanced allocations and comprehensive reforms, marking a strategic shift toward productivity-led agricultural growth. With agriculture contributing approximately 18-20% to GDP, the government aims to address ongoing challenges including climate variability, input costs, and market access through focused policy interventions.

Enhanced Budget Allocations

Agriculture allocations have demonstrated consistent growth trajectory, expanding from ₹21,933.00 crore in FY 2013-14 to over ₹1.27 lakh crore currently. For Budget 2026-27, experts anticipate further increase in agriculture budget allocation.

The increased funding is expected to support key government schemes including PM-KISAN, Pradhan Mantri Fasal Bima Yojana, and irrigation initiatives under PM Krishi Sinchayee Yojana. This allocation strategy reflects the government's commitment to enhancing farmer incomes and agricultural sustainability.

New Seeds Bill and Quality Control

The government plans to introduce comprehensive seeds legislation during the budget session, targeting the widespread issue of counterfeit and low-quality seeds in the market. The proposed bill establishes stringent quality control measures with significant enforcement mechanisms.

This legislation aims to guarantee seed quality, protect farmers against agricultural losses, and enhance overall productivity. The bill is expected to benefit established seed companies including Kaveri Seeds, Mangalam Seeds, and Bombay Super Hybrid Seeds. Fertilizer companies such as UPL Ltd, PI Industries Ltd, Sumitomo Chemical India, Bayer CropScience Ltd, and Dhanuka Agritech Ltd are also positioned to gain from improved quality standards.

Infrastructure and Technology Initiatives

Budget 2026 is expected to introduce Kavach 4.0, an advanced automatic train protection system, alongside continued electrification of remaining railway routes. The transportation sector aims to increase rail freight modal share from current 26% to 45% by 2030, supporting agricultural logistics efficiency.

India's logistics ecosystem has shown meaningful improvement, with logistics costs declining to approximately 13-14% of GDP. Cold-chain capacity expansion and strengthened rural connectivity have contributed to reduced post-harvest losses and improved price discovery mechanisms.

Export Focus and Global Market Access

India's agricultural and food exports currently stand at approximately ₹50-55 billion annually. Budget 2026 is expected to emphasize export facilitation, faster approval processes, and support for value-added agricultural products to help farmers and agricultural companies access global markets more effectively.

The policy framework is anticipated to support companies with integrated global supply chains, particularly those focused on crop protection, specialty chemicals, and nutrient efficiency. Integrated agri-input players like Coromandel International and Rallis India are positioned to benefit from the continued emphasis on efficiency-led growth strategies.

Market Perspective and Investment Outlook

The budget approach represents a transition from headline allocations to balance-sheet quality and earnings visibility across the agricultural value chain. Investor focus is shifting toward companies exposed to fertilizers, agro-chemicals, farm mechanization, irrigation equipment, and agri-logistics, where demand is driven by structural factors including higher cropping intensity, precision farming, and rural income normalization.
