About the Old vs New Tax Regime Calculator
Budget 2025 fundamentally changed the calculus between old and new tax regimes. The new regime now has a higher standard deduction (75,000 vs 50,000), a 60,000 rebate that makes income up to 12 lakh effectively tax-free, and a restructured 7-slab system. For many salaried employees - especially those with limited deductions - the new regime now wins by a wide margin. But for those with significant 80C, HRA, home loan interest, and 80D deductions, the old regime can still come out ahead. This calculator makes the comparison precise.
Tax Calculation (Both Regimes)
New Regime: Tax on (Gross - 75,000 std deduction), 87A rebate if taxable income ≤ 12L | Old Regime: Tax on (Gross - 50,000 std - deductions), 87A if income ≤ 5L
New regime slabs: 0%/5%/10%/15%/20%/25%/30% in 4L brackets | Old regime slabs: 0% up to 2.5L, 5% to 5L, 20% to 10L, 30% above 10L | Cess: 4% on tax in both regimes
Worked Example
Gross income 15 lakh, 80C 1.5L, HRA 1.2L, 80D 25k, no home loan
New Regime: Taxable 14.25L, Tax ~1,95,000 | Old Regime: Taxable 11.55L (after deductions), Tax ~1,78,000 | Old regime saves ~17,000
Tips & Insights
- 1
If your total deductions (80C + HRA + 80D + home loan interest) exceed 3-3.5 lakh, the old regime usually wins. Below that, new regime typically wins.
- 2
The new regime's 87A rebate (zero tax up to 12L taxable income) is powerful. Anyone with taxable income below 12L should almost always choose new regime.
- 3
Employer NPS contribution under 80CCD(2) is allowed in BOTH regimes with no cap percentage-wise. If your employer offers this, maximize it in either regime.
- 4
Switching declaration: inform your employer at the start of the financial year. You can finalize the choice when filing your ITR (July deadline).
- 5
Home loan interest deduction (Sec 24b, max 2L) is only available in old regime. If you have a home loan, factor this in - it can tip the balance decisively.
- 6
The new regime has a lower peak surcharge (25% vs 37% old regime). For very high incomes (5Cr+), the new regime wins primarily due to surcharge.
Why this matters for you
Choosing the wrong tax regime costs real money. For a 15 lakh income with typical deductions, the difference can be 20,000-50,000 per year. Over a 30-year career, that compounds to significant wealth. Yet most salaried employees make this decision based on WhatsApp forwards or their employer's default choice rather than their own numbers. This calculator makes the comparison concrete and personalized.
