Since 2020, the government has been trying to encourage individual taxpayers to move to the new income tax regime. The old regime, however, allows deductions on investments made under sections 80C, 80CC, and health insurance under 80D. This has led some taxpayers to stick with it.
The government on Saturday said the old tax regime will continue. But with the changes announced in Budget 2025, does it still make sense to use it?
Higher exemption limit and new tax slabs
Finance Minister Nirmala Sitharaman announced on February 1 that individuals earning up to Rs 12 lakh per year will not have to pay any taxes, raising the exemption threshold from Rs 7 lakh. The tax slabs have also been restructured.
Rajarshi Dasgupta, executive director-tax at AQUILAW, explains what this means by looking at an example of a 45-year-old Noida resident earning Rs 14 lakh per annum.

After the Budget, Central Board of Direct Taxes (CBDT) chairman Ravi Agrawal told Business Standard: "We would be interested to know who would want to remain in the old regime and why? About 74% people have already opted for the new regime and with these tax slabs, why would a taxpayer want to be in the old engine?"
The numbers suggest the old tax regime may be on its last legs. Under the old regime, even with all available deductions, a taxpayer would owe Rs 1,09,408. After the Budget 2025 changes take effect, the tax liability under the new regime would drop to Rs 73,008. This means, tax liability decreases by approximately 33.27% under the new regime.
