# Old vs New Tax Regime FY 2026-27: Where Is Your Break-Even?

**Category:** Tax Guide | **Published:** 2026-05-11 | **Last reviewed:** 2026-06-29 | **Author:** Mr. Harshal Harshe

The New Tax Regime gives a flat zero-tax ceiling of Rs. 12,75,000 for FY 2026-27 but disallows HRA, Section 80C, 80D, and Section 24(b). The Old Tax Regime keeps every deduction and starts taxing from Rs. 2,50,000. Break-even sits at roughly Rs. 4-5 lakh of actually-claimed deductions, not deductions you could claim in theory.

> **Myth:** The old regime always wins because it allows HRA, 80C, 80D, and home-loan deductions.
>
> **Fact:** Break-even runs on deductions actually claimed, not theoretical ones: below roughly Rs. 4,00,000 to Rs. 5,00,000 of real deductions the new regime usually wins, helped by the Rs. 60,000 [Section 87A](https://www.incometaxindia.gov.in/Pages/charts/income-tax-rates.aspx) rebate.

## When does each regime win for FY 2026-27?

> **Short answer:** The [new regime under Section 115BAC](https://www.incometaxindia.gov.in/Pages/acts/income-tax-act.aspx) gives a flat zero-tax ceiling of Rs. 12,75,000; the old regime wins once your claimed deductions exceed roughly Rs. 4,00,000 to Rs. 5,00,000.

- The new regime is the default since Budget 2024 and gives a Rs. 12,75,000 ceiling (Rs. 75,000 standard deduction plus the Rs. 60,000 [Section 87A](https://www.incometaxindia.gov.in/Pages/charts/income-tax-rates.aspx) rebate up to Rs. 12,00,000 taxable income).
- It disallows HRA exemption, Section 80C, Section 80D, Section 24(b), and most other allowance-level deductions.
- The old regime keeps every deduction but taxes from Rs. 2,50,000 with a smaller Rs. 50,000 standard deduction.
- Above roughly Rs. 4,00,000 to Rs. 5,00,000 of claimed deductions the old regime usually wins; below it the new regime wins on lower rates and the Rs. 12 lakh rebate ceiling.

## What are the FY 2026-27 slabs in both regimes?

> **Short answer:** Per the [Finance Act 2025](https://www.indiabudget.gov.in/), new-regime tax is nil up to Rs. 4,00,000 with 30% only above Rs. 24,00,000; the old regime stays nil up to Rs. 2,50,000 with 30% from Rs. 10,00,001.

A 4% Health and Education Cess applies under both regimes, with surcharge above Rs. 50 lakh. High-income earners with modest deductions gain from the new regime's wider top band; mid-income earners with a full deduction stack favour the old regime.

| New regime band | New rate | Old regime band | Old rate |
| --- | --- | --- | --- |
| Rs. 0 - Rs. 4,00,000 | Nil | Rs. 0 - Rs. 2,50,000 | Nil |
| Rs. 4,00,001 - Rs. 8,00,000 | 5% | Rs. 2,50,001 - Rs. 5,00,000 | 5% |
| Rs. 8,00,001 - Rs. 12,00,000 | 10% | Rs. 5,00,001 - Rs. 10,00,000 | 20% |
| Rs. 12,00,001 - Rs. 16,00,000 | 15% | Above Rs. 10,00,000 | 30% |
| Rs. 16,00,001 - Rs. 20,00,000 | 20% | Standard deduction Rs. 50,000 | - |
| Rs. 20,00,001 - Rs. 24,00,000 | 25% | Section 87A rebate Rs. 12,500 | - |
| Above Rs. 24,00,000 | 30% | Standard deduction Rs. 75,000 | - |

## How does the Section 87A rebate create a Rs. 12 lakh tax-free ceiling?

> **Short answer:** Budget 2025 raised the new-regime [Section 87A](https://www.incometaxindia.gov.in/Pages/charts/income-tax-rates.aspx) rebate from Rs. 25,000 to Rs. 60,000, lifting the tax-free ceiling to Rs. 12,00,000 taxable income (Rs. 12,75,000 of salary with standard deduction).

- Section 87A is a rebate, not a deduction: tax is computed at slab rates, then the rebate is subtracted from tax payable.
- At taxable income of Rs. 12,00,000 or less the rebate equals the tax and liability is zero; exceed it by Re. 1 and the rebate falls away in full, creating a marginal-relief band the calculator handles.
- The old-regime [Section 87A](https://www.incometaxindia.gov.in/Pages/charts/income-tax-rates.aspx) rebate is Rs. 12,500, taking taxable income up to Rs. 5,00,000 to zero, so the old-regime salaried ceiling is Rs. 5,50,000 with the Rs. 50,000 standard deduction.
- The rebate applies only to resident individuals (not non-residents, HUFs, or companies) and excludes capital gains taxed under Section 111A and Section 112A (long-term equity above Rs. 1.25 lakh).

## Which old-regime deductions tip the balance?

> **Short answer:** Five heads drive the old regime: [Section 80C](https://www.incometaxindia.gov.in/Pages/acts/income-tax-act.aspx) Rs. 1,50,000, Section 80D, [Section 24(b)](https://www.incometaxindia.gov.in/Pages/acts/income-tax-act.aspx) Rs. 2,00,000, Section 10(13A) HRA, and Section 80CCD(1B) Rs. 50,000, stacking Rs. 5,00,000 to Rs. 8,00,000 at full limits.

- Section 80C caps Rs. 1,50,000 (shared, not per head) across EPF, PPF, ELSS, life insurance, home-loan principal, two-child tuition, NSC, 5-year tax-saving FD, and Sukanya Samriddhi.
- Section 80D allows Rs. 25,000 for self plus family and Rs. 25,000 for parents (Rs. 50,000 if a parent is a senior citizen), with a Rs. 5,000 preventive check-up sub-limit inside the cap.
- Section 24(b) allows Rs. 2,00,000 home-loan interest for self-occupied property; let-out interest is uncapped but house-property loss set-off is capped at Rs. 2,00,000 a year, residual carried forward up to 8 assessment years.
- [Section 10(13A) HRA](https://www.incometaxindia.gov.in/Pages/acts/income-tax-act.aspx) exemption is the minimum of actual HRA, rent minus 10% of basic, and 50% of basic for metros (40% non-metro), often Rs. 1,50,000 to Rs. 3,00,000 a year in high-rent metros.
- Section 80CCD(1B) adds Rs. 50,000 for NPS over the 80C cap; the new regime concedes only a higher Rs. 75,000 standard deduction versus Rs. 50,000.

## Where is the break-even across four salary profiles?

> **Short answer:** Deduction-heavy salaries between Rs. 12,00,000 and Rs. 25,00,000 with HRA plus home loan favour the old regime; deduction-light or high-end salaries favour the new regime, all figures including 4% cess.

| Profile | New-regime final tax | Old-regime final tax | Winner |
| --- | --- | --- | --- |
| A: Rs. 8,00,000 gross, 80C Rs. 50,000 only | Rs. 0 (Rs. 7,25,000 taxable, Rs. 60,000 rebate) | Rs. 54,600 (Rs. 7,00,000 taxable) | NEW by Rs. 54,600 |
| B: Rs. 15,00,000 gross, HRA 2L / 80C 1.5L / 80D 25k / 24(b) 2L / NPS 50k | Rs. 1,33,900 (Rs. 14,25,000 taxable) | Rs. 80,600 (Rs. 8,25,000 taxable) | OLD by Rs. 53,300 |
| C: Rs. 30,00,000 gross, 80C 1.5L / 80D 25k only | Rs. 5,38,200 (Rs. 29,25,000 taxable) | Rs. 6,83,800 (Rs. 27,75,000 taxable) | NEW by Rs. 1,45,600 |
| D: Rs. 20,00,000 gross, HRA 1.5L / 80C 1.5L / 80D 50k / 24(b) 2L | Rs. 2,56,100 (Rs. 19,25,000 taxable) | Rs. 2,41,800 (Rs. 14,00,000 taxable) | OLD by Rs. 14,300 |

## What seven inputs does the calculator need?

> **Short answer:** The browser-only [Tax Optimization Calculator](/tax-calculator) needs gross salary, salary structure, city tier, annual rent, Section 80C, Section 80D, and Section 24(b) interest; no salary or PAN data leaves your device.

- Gross annual salary (CTC minus employer PF) and the salary structure (basic, HRA, DA, special allowances), since HRA exemption depends on basic, not gross.
- City tier sets the HRA cap under Section 10(13A): the eight metros (Delhi, Mumbai, Kolkata, Chennai, Bengaluru, Hyderabad, Pune, Ahmedabad) raise the exemption ceiling to 50% of basic salary, versus 40% everywhere else; the calculator uses the FY 2026-27 eight-city list.
- Actual annual rent paid, which feeds the third leg of the HRA minimum (rent paid minus 10% of basic); leave at zero if no rent is paid.
- Section 80C capped at Rs. 1,50,000, Section 80D premiums (with senior-citizen flag), and Section 24(b) interest capped at Rs. 2,00,000 for self-occupied property.
- Edge cases: NPS Section 80CCD(1B) Rs. 50,000 add-on, Section 89(1) arrears relief with a Form 10E reminder, senior-citizen age, and surcharge bands above Rs. 50 lakh.

## What changed for FY 2026-27 versus FY 2024-25?

> **Short answer:** [Budget 2025](https://www.indiabudget.gov.in/) made three new-regime changes effective FY 2025-26 and continuing into FY 2026-27; the old regime stayed unchanged.

- Slab compression: the lowest taxable bracket now starts at Rs. 4,00,000 (was Rs. 3,00,000) and the 30% slab at Rs. 24,00,000 (was Rs. 15,00,000), easing incomes between Rs. 15,00,000 and Rs. 24,00,000 most.
- The new-regime Section 87A rebate rose to Rs. 60,000 (was Rs. 25,000), pushing the tax-free ceiling from Rs. 7,00,000 to Rs. 12,00,000 of taxable income.
- The salaried tax-free ceiling is now Rs. 12,75,000, combining the Rs. 12,00,000 rebate ceiling with the Rs. 75,000 standard deduction.
- The old regime is unchanged: nil to Rs. 2,50,000, 5% to Rs. 5,00,000, 20% to Rs. 10,00,000, 30% above, with a Rs. 12,500 rebate and Rs. 50,000 standard deduction.
- The Rs. 60,000 rebate flips many Rs. 8,00,000 to Rs. 13,00,000 salary cases to the new regime, so prior-year guidance no longer transfers cleanly.

## How do Form 10-IEA, Section 89(1) arrears, and the year-of-switch trap work?

> **Short answer:** ITR-3 / ITR-4 filers with business income must file [Form 10-IEA](https://www.incometax.gov.in/iec/foportal/) before the due date to opt into the old regime; the choice is annual and switching back is once-in-a-lifetime for them.

- Salaried filers with no business income switch to the old regime inside the ITR-1 / ITR-2 flow each year; business and professional income filers must file Form 10-IEA before the original due date, after which switching back is allowed only once in a lifetime.
- [Section 89(1)](https://www.incometaxindia.gov.in/Pages/acts/income-tax-act.aspx) relieves salary arrears by notionally taxing them at the slab of the relevant year, but Form 10E must be filed on the e-Filing portal first or the relief is disallowed.
- Regime choice is annual with no mid-year switch, so confirm it with your employer before April 1 so TDS runs under the chosen regime.
- Old-regime employees claiming HRA must submit rent receipts plus the landlord PAN for annual rent above Rs. 1,00,000, alongside Form 12BB; rent receipt plus a payment receipt carrying the UTR is the two-document rule.
