The ₹3.5 Lakh Mistake: How Defaulting to New Tax Regime Costs Mumbai Home Buyers

Introduction to the ₹3.5 Lakh Mistake

For Mumbai home buyers, the new tax regime has brought an unintended consequence: a potential loss of ₹1.05 lakh in tax savings per year. This amount can be substantial, especially when considering the current home loan rates, such as SBI's 7.5% and HDFC's 7.75%. As of May 2026, many salaried Indians have auto-defaulted to the new regime without realizing the implications on their home loan tax deductions.

Understanding the Old Tax Regime Benefits

Under the old tax regime, home loan interest (up to ₹2 lakh under Section 24b) and principal (up to ₹1.5 lakh under Section 80C) can be deducted, resulting in a total deduction of ₹3.5 lakh per year. For individuals in the 30% tax slab, this translates to actual tax savings of ₹1.05 lakh (30% of ₹3.5 lakh). To put this into perspective, consider a home buyer in Mumbai with a home loan of ₹50 lakh at 7.5% interest rate. Using the NestSaver EMI Calculator, we can calculate the annual interest payment to be approximately ₹3.75 lakh.

Who Should Switch Back to the Old Regime?

Individuals who have a home loan and are in the higher tax slabs (20% and 30%) are likely to benefit from switching back to the old regime. Additionally, those who have other deductions, such as investments in PPF or NSC, may also find it advantageous to opt for the old regime. The following table illustrates the tax savings for different tax slabs:

How to Switch Back to the Old Regime

To switch back to the old regime, individuals need to file a claim with the income tax department. This can be done by filling out Form 10IE and submitting it to the income tax website. The deadline for filing this claim is December 31, 2026. It is essential to note that once the old regime is opted for, it will be applicable for the entire financial year.

Impact of RBI Rate Hike on Home Loan Rates

The current home loan rates, such as Axis' 7.85% and Kotak's 7.9%, may be affected by the potential RBI rate hike in June 2026. To understand the impact of this rate hike on home loan rates, visit the RBI Rate Hike Impact by City page. This will help home buyers make informed decisions about their loan options.

Comparing Home Loan Rates Across Banks

With the current home loan rates ranging from 7.5% to 7.9%, it is crucial to compare rates across different banks to find the most suitable option. The Bank Rate Comparison page provides a comprehensive comparison of home loan rates across various banks, including SBI, HDFC, and ICICI. Additionally, the Loan Doctor tool can help home buyers analyze their loan options and make informed decisions.
