Is the Old Tax Regime Dead? The FY 2026-27 Break-Even Math
Published July 6, 2026 • By Upaman Research Team • Reviewed by Personal Finance Review Desk
Every year the same question returns at tax-declaration time: old regime or new? For FY 2026-27 (AY 2027-28) the honest answer for most salaried people has quietly become the new regime— not because the old one changed, but because the new regime’s ₹75,000 standard deduction and the Section 87A rebate up to ₹12 lakh have raised the bar the old regime has to clear. We computed exactly how high that bar is.
The break-even deduction— how much you must claim under the old regime just to match the new regime’s tax — is ₹6.5 lakh at a ₹12L salary, ₹5.45L at ₹15L, ₹7.1L at ₹20L, and about ₹8L at ₹25L. Below those, the new regime is cheaper.
What each regime costs before any deductions
Start with the baseline: the new regime tax after only its ₹75,000 standard deduction, against the old regime tax after only its ₹50,000 standard deduction and nothing else claimed.
| Gross salary | New regime tax | Old regime (no deductions) | Break-even deductions |
|---|---|---|---|
| ₹12,00,000 | ₹0 | ₹1,63,800 | ≈ ₹6,50,000 |
| ₹15,00,000 | ₹97,500 | ₹2,57,400 | ≈ ₹5,45,000 |
| ₹20,00,000 | ₹1,92,400 | ₹4,13,400 | ≈ ₹7,10,000 |
| ₹25,00,000 | ₹3,19,800 | ₹5,69,400 | ≈ ₹8,00,000 |
At ₹12 lakh the new regime tax is literally zero thanks to the 87A rebate, so the old regime would need ₹6.5 lakh of deductions just to reach nil as well — a very high bar for most single earners.
Can you realistically hit ₹5–8 lakh in deductions?
Add up the usual old-regime levers and the ceiling arrives faster than people expect:
- Section 80C — capped at ₹1.5 lakh (EPF, PPF, ELSS, life insurance, principal repayment).
- Section 80D — health insurance, roughly ₹25,000–₹75,000 depending on age and parents.
- NPS 80CCD(1B) — an extra ₹50,000.
- Home-loan interest (Section 24) — up to ₹2 lakh on a self-occupied property.
- HRA — the wildcard; large only for renters in metros with a high basic salary.
Stack 80C + 80D + NPS and you reach roughly ₹2.5 lakh. Getting to ₹5–8 lakh essentially requires a running home loan and substantial HRA at the same time. That describes some taxpayers — but not most.
The discipline test: the old regime only wins if you would make those tax-saving commitments anyway. If you would buy the insurance and lock money into 80C purely to beat the new regime, the paperwork, lock-ins and cash-flow drag usually cost more than the tax saved.
So is the old regime dead?
Not dead — but narrowed to a specific profile: a homeowner still paying meaningful loan interest, renting in a metro on a high basic, and already maxing 80C and health cover. For a salaried person without a home loan, the new regime is now the simpler and usually cheaper default, and the gap widens as income rises.
Run your own numbers rather than trusting a rule of thumb: the income tax calculator compares both regimes with your actual deductions, and the break-even guide and regime-choice guide walk through the decision step by step. For a specific salary, the tax-on-salary pages show the full slab breakdown.
Figures are FY 2026-27 estimates computed with Upaman’s Indian income-tax engine for a salaried individual; they include the 4% cess and the Section 87A rebate but exclude surcharge and special-rate income. Break-even deductions are the additional old-regime deductions (beyond the ₹50,000 standard deduction) needed to match the new-regime tax. Not tax advice — verify on the Income Tax Department portal.
