BREAK-EVEN

The cross-over point

Break-even deduction = ₹6,06,251. If you have less than this in total old-regime deductions, new regime is better; more than this, old regime wins.

Your current old-regime total deduction is ₹6,25,000above the break-even.

IMPORTANT

Default to new regime

From FY 2023-24, the new regime is the DEFAULT. You must explicitly opt for old regime in your ITR (Form 10-IEA for salaried). The ₹12L zero-tax threshold under new regime (post-Budget 2025) made it dominant for most salaried; check the comparison before filing.

How It Works

This calculator computes your annual income tax under both the old and new tax regimes side-by-side for FY 2026-27 (AY 2027-28) and shows which regime saves more for your specific deduction profile. The new regime under Section 115BAC is the default from FY 2023-24; the old regime requires explicit opt-out via Form 10-IEA for salaried taxpayers.

Key differences

The new regime has lower slab rates and a much higher Section 87A rebate (full rebate up to ₹12L taxable income, capped at ₹60K), but allows almost no itemised deductions — only the ₹75,000 standard deduction (salaried) and the employer NPS contribution u/s 80CCD(2) up to 14% of basic. The old regime uses higher slab rates and a lower ₹50,000 standard deduction, but lets you claim 80C (up to ₹1.5L), 80CCD(1B) (₹50K NPS extra), 80D (₹25K health), 24(b) (₹2L home loan interest), HRA, LTA, and other deductions.

The break-even rule

The break-even deduction depends on your gross income. At ₹15L gross salary, you typically need ₹4-6L of total deductions for the old regime to win; below that, the new regime saves more. This calculator computes the exact break-even for your inputs so you can see how much you would need to deduct to make switching worthwhile.

What this calculator simplifies

Surcharge (applicable above ₹50L) is intentionally out of scope here — use the full Income Tax Calculator for high-income surcharge modelling. The 80D cap is fixed at ₹25K (regular taxpayer); senior-citizen ₹50K bucket is not modelled.

Frequently Asked Questions

It depends on how much you actually deduct. The new regime has lower slab rates and a zero-tax band up to ₹12L taxable income (₹12.75L gross for salaried). The old regime offers itemised deductions (80C up to ₹1.5L, 80D up to ₹25K, 80CCD(1B) NPS up to ₹50K, 24(b) home loan interest up to ₹2L, HRA, LTA) that can knock taxable income down sharply. Rule of thumb at ₹15L gross: if your combined deductions clear roughly ₹4-6L the old regime usually wins, otherwise the new regime wins. The break-even depends on income level — at higher incomes the new regime's lower rates often beat even maximum old-regime deductions.
