Overview of Two Tax Regimes
New Regime: Simpler tax with lower tax rates but NO deductions allowed (except standard ₹75K). Old Regime: Traditional tax with higher slabs BUT many deductions allowed (80C, 80D, HRA, home loan interest, NPS). From FY 2023-24, New Regime is default, but you can choose Old Regime.
New Tax Regime Slabs 2025-26
Up to ₹3L: Nil. ₹3-6L: 5%. ₹6-9L: 10%. ₹9-12L: 15%. ₹12-15L: 20%. Above ₹15L: 30%. Rebate 87A: If income ≤ ₹7L, full tax relief up to ₹25,000. Standard deduction: ₹75,000. No Section 80C, 80D, HRA, or home loan interest deductions allowed.
Old Tax Regime Slabs 2025-26
Up to ₹2.5L: Nil. ₹2.5-5L: 5%. ₹5-10L: 20%. ₹10-20L: 30%. Above ₹20L: 30%. Deductions: Section 80C (₹1.5L), 80D (₹75K), HRA (40% of basic), home loan interest (₹2L), Section 80CCD (₹2L). Standard deduction: ₹75,000. More complex but saves more tax for higher incomes.
Real Comparison Examples
₹8L income, no deductions: New saves ₹30K. ₹12L income with ₹4.75L deductions: Old saves ₹22,100. ₹20L income with max deductions ₹10L: Old saves ₹1,06,600. Rule: If total deductions > ₹1L, Old regime usually better. Below ₹1L deductions, New regime simpler.
Decision Factors
Choose New Regime: Income ₹5-8L with minimal deductions, prefer simplicity, no home loan/insurance yet. Choose Old Regime: Income > ₹10L, active home loan (interest ₹1.5-2L), regular insurance/PPF investments (₹1.5L/year), want maximum tax benefit. You can switch every year!
Best Strategy: Calculate Both
File ITR showing calculations for both regimes. Choose the one giving lower tax. For income ₹8-12L, difference can be ₹15-30K per year. At filing time, software calculates both automatically. No need to choose upfront - decide based on actual numbers.
Frequently Asked Questions
Can I choose new regime then switch to old regime next year?▾
Yes! You can switch every year. New regime Year 1 (if income < ₹8L), then Old regime Year 2-5 (if deductions increase with home loan, insurance). No permanent choice required.
At what income should I switch to old regime?▾
Rule of thumb: Switch to Old Regime if income > ₹10L AND have deductions > ₹1L. For income ₹8-10L, compare both. Below ₹8L, New Regime (Rebate 87A gives full relief).
Does HRA exemption differ between regimes?▾
No, HRA exemption rules are same in both regimes (40% of basic in metro, 30% in non-metro). Old Regime requires you to calculate correctly; New Regime also exempts full HRA.
Can I claim rebate 87A in both regimes?▾
Rebate 87A is most beneficial in New Regime (gives full tax relief if income ≤ ₹7L). In Old Regime, rebate applies but is usually not full relief if income > ₹7L.
What if my income increases during the year?▾
You still file for full-year income. Progressive tax rates apply: up to ₹3L is 0%, ₹3-6L is 5%, etc. Higher income just moves you to higher slab, not retroactive.
