Income Tax Under the Old Regime: Maximizing Deductions for FY 2025-26
The old income tax regime remains a powerful option for taxpayers who can leverage India's extensive system of deductions and exemptions. While the new regime has become the default from FY 2023-24, the old regime continues to offer significant tax savings for individuals who actively invest in tax-saving instruments, pay rent, have a home loan, or hold health insurance policies.
Old Regime Tax Slabs for FY 2025-26
The old regime follows a three-slab structure for individual taxpayers below 60 years of age. Income up to Rs 2,50,000 is exempt. Income between Rs 2,50,000 and Rs 5,00,000 is taxed at 5%. Income between Rs 5,00,000 and Rs 10,00,000 is taxed at 20%. Income above Rs 10,00,000 is taxed at 30%.
Key Deductions Available Under the Old Regime
Section 80C — Rs 1,50,000
The cornerstone of tax planning in India, Section 80C allows a deduction of up to Rs 1,50,000 for investments and expenses including EPF, PPF, ELSS, NSC, 5-year FDs, LIC premiums, home loan principal repayment, Sukanya Samriddhi Yojana, and children's tuition fees (up to 2 children).
Section 80D — Health Insurance Premiums
Up to Rs 25,000 for self, spouse, and dependent children (Rs 50,000 for senior citizens). An additional Rs 25,000 (or Rs 50,000 for senior citizen parents) is available for parents' health insurance.
HRA Exemption — Section 10(13A)
If you receive HRA and pay rent, a portion is exempt from tax. Use our HRA Calculator for a precise computation.
Section 24(b) — Home Loan Interest
Interest paid on a home loan for a self-occupied property is deductible up to Rs 2,00,000 per financial year — one of the most substantial deductions available.
When the Old Regime Makes Sense
The old regime is typically superior when your total deductions exceed Rs 3.75 lakh for incomes around Rs 15-20 lakh. This is common for individuals with a home loan, significant rent in a metro city, 80C investments, and health insurance.
