Old vs New Regime FY 2026-27: Break-Even + Calculator

For FY 2026-27 (assessment year 2027-28), salaried Indians choose between two regimes. The new regime under Section 115BAC is the default since Budget 2024 and gives a flat zero-tax ceiling of Rs. 12,75,000 (Rs. 75,000 standard deduction plus the Rs. 60,000 Section 87A rebate up to Rs. 12,00,000 of taxable income), but disallows HRA exemption, Section 80C, Section 80D, Section 24(b), and most other allowance-level deductions. The old regime keeps every deduction but starts taxing from Rs. 2,50,000 and gives a smaller standard deduction of Rs. 50,000.

The break-even sits at the level of deductions you claim in practice, not the level you could claim in theory. The rule of thumb: if your total old-regime deductions (HRA + 80C + 80D + 24(b) + standard deduction) exceed roughly Rs. 4,00,000 to Rs. 5,00,000, the old regime is usually better. Below that, the new regime wins on the lower rates and the Rs. 12 lakh rebate ceiling. The exact breakeven shifts by salary level. The Income Tax Department's Tax Optimization Calculator computes both side by side from a single set of inputs and tells you the optimal regime in rupee terms.

The four salary profiles that decide your regime, the seven inputs the calculator needs, and the structural shifts that landed in Budget 2025 and continue into FY 2026-27.

**New regime slabs (default, FY 2026-27 / AY 2027-28).** Per the Finance Act 2025, the slabs apply to resident individuals (including senior citizens) under Section 115BAC of the Income Tax Act:

• Rs. 0 – Rs. 4,00,000: Nil

• Rs. 4,00,001 – Rs. 8,00,000: 5%

• Rs. 8,00,001 – Rs. 12,00,000: 10%

• Rs. 12,00,001 – Rs. 16,00,000: 15%

• Rs. 16,00,001 – Rs. 20,00,000: 20%

• Rs. 20,00,001 – Rs. 24,00,000: 25%

• Above Rs. 24,00,000: 30%

A Health and Education Cess of 4% applies on the tax payable. Surcharge applies above Rs. 50 lakh. Standard deduction for salaried employees is Rs. 75,000.

**Old regime slabs (opt-in, FY 2026-27).** No change from prior years:

• Rs. 0 – Rs. 2,50,000: Nil

• Rs. 2,50,001 – Rs. 5,00,000: 5%

• Rs. 5,00,001 – Rs. 10,00,000: 20%

• Above Rs. 10,00,000: 30%

Standard deduction is Rs. 50,000. Section 87A rebate is Rs. 12,500, taking effective tax to zero up to Rs. 5,00,000 of taxable income.

The shape difference matters. The new regime spreads its top rate across a wider band (30% kicks in only above Rs. 24 lakh), where the old regime hits 30% from Rs. 10,00,001. For high-income earners with modest deductions, the new regime's flatter top end is the structural advantage. For mid-income earners with significant deductions (HRA, home loan, 80C in full), the old regime's deduction stack outweighs the slab penalty. The income-tax slabs reference for FY 2026-27 carries the full slab + rebate + standard-deduction reference table.

Under Section 87A, resident individuals pay zero income tax up to a defined ceiling of taxable income. Budget 2025 raised the new-regime rebate from Rs. 25,000 to Rs. 60,000, pushing the tax-free ceiling from Rs. 7,00,000 to Rs. 12,00,000. With the Rs. 75,000 standard deduction added on top, the salaried-employee tax-free ceiling under the new regime is Rs. 12,75,000 of gross salary.

**Mechanics.** Section 87A is a rebate, not a deduction. The taxpayer first computes tax on taxable income at the slab rates, then subtracts the Section 87A rebate from the tax payable. Where taxable income is Rs. 12,00,000 or less, the rebate equals the tax payable, taking the final liability to zero. Where taxable income exceeds Rs. 12,00,000 by even Re. 1, the rebate falls away in full and the entire slab tax is payable, creating a marginal-relief band that the calculator handles automatically.

**Old-regime Section 87A.** The rebate under the old regime is Rs. 12,500, taking taxable income up to Rs. 5,00,000 to zero tax. With the Rs. 50,000 standard deduction, salaried-employee tax-free ceiling under the old regime is Rs. 5,50,000.

**Eligibility.** The rebate applies only to resident individuals. Non-residents, HUFs, and companies do not qualify. The rebate also applies only on income taxed at slab rates; capital gains taxed under special rates (Section 111A short-term equity, Section 112A long-term equity above Rs. 1.25 lakh) are excluded from the rebate computation, so the rebate may not zero them out even where total income is below the ceiling.

Five deduction categories drive the old regime's competitive advantage. A taxpayer claiming all five at full statutory limits stacks Rs. 5,00,000 to Rs. 8,00,000 of deductions before the slab tax runs.

**1. Section 80C: Rs. 1,50,000.** Investments and payments in EPF, PPF, ELSS mutual funds, life-insurance premiums, principal repayment of home loan, tuition fees for two children, NSC, tax-saving fixed deposit (5-year), and Sukanya Samriddhi Yojana. The Rs. 1.5 lakh limit is shared across all heads, not per head. Most salaried employees fill 80C by mid-year via EPF deduction alone.

**2. Section 80D: health insurance.** Up to Rs. 25,000 for self + family premiums, plus Rs. 25,000 for parents' health insurance (or Rs. 50,000 if either parent is a senior citizen). Senior-citizen taxpayers themselves can claim Rs. 50,000 instead of Rs. 25,000. Preventive health check-up sub-limit is Rs. 5,000 within the overall cap.

**3. Section 24(b): home-loan interest.** Up to Rs. 2,00,000 for a self-occupied property. For a let-out property, the deduction is the full interest paid (no cap), but the loss-from-house-property is capped at Rs. 2,00,000 per year for set-off against other income; the residual carries forward up to 8 assessment years.

**4. Section 10(13A): HRA exemption.** Available to salaried employees living in rented accommodation. The exempt amount is the minimum of: actual HRA received, rent paid minus 10% of basic salary, and 50% of basic salary (40% for non-metro cities). For metro-city employees in high-rent locations, HRA exemption alone often exceeds Rs. 1,50,000 to Rs. 3,00,000 per year. The HRA exemption calculation walkthrough covers the three-part formula with worked examples.

**5. Section 80CCD(1B): NPS additional.** Rs. 50,000 over and above the Section 80C cap, applied only to National Pension System contributions. Independent of the Rs. 1.5 lakh 80C cap.

**Standard deduction.** Old regime: Rs. 50,000. New regime: Rs. 75,000. The new regime's higher standard deduction is the new regime's only deduction concession; everything else has been swept away.

Where a taxpayer claims all five at material levels, total deductions land in the Rs. 5,00,000 to Rs. 8,00,000 range. At those levels, the old regime usually wins for taxable salaries between Rs. 12,00,000 and Rs. 25,00,000, where the slab rate gap is widest.

Four salary profiles cover the bulk of the salaried population. The break-even points below assume the old-regime deductions are claimed in full at the levels stated; partial claims shift the answer.

**Profile A: Junior salaried, Rs. 8,00,000 gross, minimal deductions (80C via EPF only at Rs. 50,000, no HRA, no 80D, no home loan).**

• New regime: gross Rs. 8,00,000 - standard deduction Rs. 75,000 = taxable Rs. 7,25,000. Tax under new slabs = Rs. 16,250. Section 87A rebate Rs. 60,000 zeros it out. Final tax = Rs. 0.

• Old regime: gross Rs. 8,00,000 - standard deduction Rs. 50,000 - 80C Rs. 50,000 = taxable Rs. 7,00,000. Tax = Rs. 52,500. Section 87A rebate Rs. 0 (income above Rs. 5,00,000). Final tax = Rs. 54,600 (with cess).

• **Winner: NEW regime by Rs. 54,600.**

**Profile B: Mid-career salaried, Rs. 15,00,000 gross, full deduction stack (HRA Rs. 2,00,000 / 80C Rs. 1,50,000 / 80D Rs. 25,000 / 24(b) Rs. 2,00,000 / NPS Rs. 50,000).**

• New regime: gross Rs. 15,00,000 - standard deduction Rs. 75,000 = taxable Rs. 14,25,000. Tax = Rs. 1,28,750. Section 87A rebate Rs. 0 (income above Rs. 12 lakh). Final tax = Rs. 1,33,900 (with cess).

• Old regime: gross Rs. 15,00,000 - standard Rs. 50,000 - HRA Rs. 2,00,000 - 80C Rs. 1,50,000 - 80D Rs. 25,000 - 24(b) Rs. 2,00,000 - NPS Rs. 50,000 = taxable Rs. 8,25,000. Tax = Rs. 77,500. Final tax = Rs. 80,600 (with cess).

• **Winner: OLD regime by Rs. 53,300.**

**Profile C: High-income salaried, Rs. 30,00,000 gross, partial deductions (80C Rs. 1,50,000 / 80D Rs. 25,000 only, no HRA and no home loan).**

• New regime: gross Rs. 30,00,000 - standard deduction Rs. 75,000 = taxable Rs. 29,25,000. Tax = Rs. 5,17,500. Final tax = Rs. 5,38,200 (with cess).

• Old regime: gross Rs. 30,00,000 - standard Rs. 50,000 - 80C Rs. 1,50,000 - 80D Rs. 25,000 = taxable Rs. 27,75,000. Tax = Rs. 6,57,500. Final tax = Rs. 6,83,800 (with cess).

• **Winner: NEW regime by Rs. 1,45,600.**

**Profile D: Senior with home loan, Rs. 20,00,000 gross, HRA Rs. 1,50,000 / 80C Rs. 1,50,000 / 80D Rs. 50,000 (parents senior) / 24(b) Rs. 2,00,000.**

• New regime: taxable Rs. 19,25,000. Tax = Rs. 2,46,250. Final = Rs. 2,56,100 (with cess).

• Old regime: taxable Rs. 14,00,000. Tax = Rs. 2,32,500. Final = Rs. 2,41,800 (with cess).

• **Winner: OLD regime by Rs. 14,300.**

The pattern: deduction-heavy mid-band (Rs. 12,00,000 to Rs. 25,00,000 with HRA + home loan) favours old; deduction-light or high-end favours new. The exact break-even shifts with each input. Run your own numbers in the Tax Optimization Calculator to get the rupee answer for your specific situation.

The Tax Optimization Calculator at hrareceipt.in computes both regimes side by side from a single set of inputs and returns the optimal regime call in rupee terms. The calculator runs entirely in the browser; no salary or PAN data leaves your device.

**Input 1: Gross annual salary.** Total cost-to-company minus employer PF contribution. The figure on your offer letter or salary slip CTC line.

**Input 2: Salary structure breakdown.** Basic salary, HRA component, dearness allowance (DA), and special allowances. The structure decides HRA exemption (which depends on basic, not gross) and the relevant breakdown for the old regime.

**Input 3: City tier.** Metro (Delhi, Mumbai, Kolkata, Chennai, on the Rule 2A 50% HRA basis) versus non-metro (40% HRA basis). The eight-city Rule 279 list (which adds Bengaluru, Hyderabad, Pune, Ahmedabad to the Rule 2A four) does not change the HRA computation; the metro/non-metro split for HRA is governed by Rule 2A only.

**Input 4: Actual rent paid annually.** The rent figure feeds the third leg of the HRA three-part minimum (rent paid minus 10% of basic salary). For salaried employees not paying rent, leave at zero; HRA exemption goes to zero and only the basic-and-DA combination determines old-regime salary tax.

**Input 5: Section 80C investments.** Total of EPF (employee + employer share counts only on employee), PPF, ELSS, life-insurance premiums, home-loan principal, child tuition, etc. Cap at Rs. 1,50,000.

**Input 6: Section 80D health-insurance premium.** Self + family premium, plus parents' premium (with senior-citizen flag if applicable).

**Input 7: Section 24(b) home-loan interest.** Interest portion of EMIs paid in the year, capped at Rs. 2,00,000 for self-occupied property. The principal portion goes into Section 80C.

Optional inputs the calculator handles for edge cases: NPS Section 80CCD(1B) Rs. 50,000 add-on, Section 89(1) salary-arrears relief (with Form 10E reminder), age (for senior-citizen Section 87A treatment), and surcharge bands above Rs. 50 lakh. The output ranks the two regimes by net tax payable and shows the savings from picking the optimal one.

Budget 2025 (announced February 2025, effective from FY 2025-26 and continuing into FY 2026-27) made three changes to the new regime; the old regime stayed unchanged.

**1. New-regime slab compression.** The lowest taxable bracket starts at Rs. 4,00,000 (was Rs. 3,00,000) and the highest 30% slab now starts at Rs. 24,00,000 (was Rs. 15,00,000). The widened top band reduces the tax burden on incomes between Rs. 15,00,000 and Rs. 24,00,000 most.

**2. Section 87A rebate raised.** New-regime rebate now Rs. 60,000 (was Rs. 25,000), pushing the new-regime tax-free ceiling from Rs. 7,00,000 to Rs. 12,00,000 of taxable income.

**3. Salaried tax-free ceiling now Rs. 12,75,000.** Combination of Rs. 12,00,000 Section 87A ceiling plus Rs. 75,000 standard deduction.

The old-regime numbers stayed the same: slabs (nil up to Rs. 2,50,000 / 5% to Rs. 5,00,000 / 20% to Rs. 10,00,000 / 30% above), Rs. 12,500 Section 87A rebate, and Rs. 50,000 standard deduction.

**Practical impact on the regime choice.** Before Budget 2025, the new regime was a tougher sell for mid-income salaried with deductions. The Rs. 60,000 rebate flips many Rs. 8,00,000 to Rs. 13,00,000 salary cases to the new regime even where the old-regime stack would have won under the older Rs. 25,000 rebate regime. Run your own numbers; the shift is large enough that prior-year guidance does not transfer cleanly.

**Form 10-IEA opt-in.** The new regime is the default. Salaried employees with no business or professional income switch to the old regime by selecting it in the ITR-1 / ITR-2 filing flow each year. Employees with business or professional income (ITR-3 / ITR-4 filers) must file Form 10-IEA on the Income Tax e-Filing portal before the original due date for the return, formally opting into the old regime. Once opted out of the new regime via Form 10-IEA, the option to switch back is allowed only once in a lifetime for non-business taxpayers.

**Section 89(1) salary-arrears relief.** Where a salaried employee receives arrears or advance salary that pushes the year's taxable income into a higher slab, Section 89(1) provides relief by allowing the arrears to be notionally taxed at the slab applicable to the year the arrears related to. The taxpayer files Form 10E on the e-Filing portal before claiming the relief in ITR. Without Form 10E, the relief is disallowed and the arrears land in the higher slab. The Tax Optimization Calculator surfaces this with a Form 10E reminder when arrears are entered.

**Year-of-switch trap.** Switching regime mid-financial-year is not allowed; the choice is annual. Salaried employees should confirm regime choice with their employer at the start of each financial year so TDS is computed under the chosen regime month by month. Switching from new to old at ITR filing time when TDS was deducted under the new regime triggers a refund cycle; switching from old to new triggers a balance-due. Either way, the cash-flow timing impacts the year. The cleaner pattern: pick the regime via the calculator before April 1, communicate it to payroll, and let TDS run accordingly.

**HRA submission discipline (old regime).** Old-regime employees claiming HRA must submit rent receipts and (for annual rent above Rs. 1,00,000) the landlord's PAN to their employer. The two-document rule for defensible claims: rent receipt + payment receipt with UTR, both submitted alongside Form 12BB. The Form 12BB complete guide covers field-by-field submission, and the HR-side verification angle covers what payroll teams check before applying HRA in TDS computation. For tax-compliant rent and payment receipts, use the rent receipt generator and the payment receipt generator; the pair issues both in one workflow.
