FY2026-27 Tax Guide for Salaried Employees:
Slabs, the New Income Tax Act & a Built-in Calculator

If you are a salaried employee, April 2026 quietly marked one of the biggest structural changes in Indian taxation in six decades: the Income Tax Act, 2025 replaced the Income Tax Act, 1961 with effect from 1 April 2026. The good news for your salary slip — Budget 2026 made no change to tax slab rates, the standard deduction, or the rebate. Your FY2026-27 tax works on the same numbers as FY2025-26. What changed is the law's structure, language, and forms.

This guide gives you everything needed to pre-plan the year: the confirmed slabs, what the new Act actually changes for you, worked examples at common salary levels, a month-by-month planning checklist, and an interactive calculator right inside this page.

1. What Budget 2026 Did (and Did Not) Change

• No slab changes. Both regimes continue with the FY2025-26 structure.
• Standard deduction stays ₹75,000 under the new regime for salaried individuals and pensioners (₹50,000 under the old regime).
• Rebate continues. The rebate (formerly Section 87A; renumbered under the new Act) keeps taxable income up to ₹12 lakh at zero tax under the new regime.
• Employer NPS contribution remains deductible up to 14% of basic salary under the new regime — one of the few deductions the new regime allows.
• The Income Tax Act, 2025 takes effect. Rates are unchanged, but the law is rewritten: a single "Tax Year" replaces "Assessment Year" and "Previous Year", sections are renumbered, and return forms are redesigned to be simpler.

2. FY2026-27 Slabs — New Regime (Default)

Plus: rebate up to ₹60,000 wipes out tax for taxable income up to ₹12 lakh → with the ₹75,000 standard deduction, a salary of ₹12.75 lakh is effectively tax-free. Health & education cess of 4% applies on tax payable. Marginal relief protects those just above ₹12 lakh from a cliff.

3. FY2026-27 Slabs — Old Regime (Optional)

The old regime keeps its full deduction menu: 80C (₹1.5 lakh), 80D health insurance, HRA exemption, home-loan interest under Section 24(b) (₹2 lakh), LTA, 80CCD(1B) NPS (₹50,000), and more. Rebate of ₹12,500 applies up to ₹5 lakh taxable income.

5. Worked Examples — Five Real Salary Levels

Example A — ₹8 lakh salary (entry/mid level)

New regime: ₹8,00,000 − ₹75,000 = ₹7,25,000 taxable → tax ₹16,250 → fully wiped by rebate → ₹0.
Old regime (₹1.5L 80C): taxable ₹6,00,000 → tax ₹32,500 + cess = ₹33,800.
Verdict: New regime, no contest — and you keep ₹1.5 lakh free to invest as you wish instead of locking it for a deduction.

Example B — ₹12.75 lakh salary (the sweet spot)

New regime: ₹12,75,000 − ₹75,000 = ₹12,00,000 → computed tax ₹60,000 → rebate ₹60,000 → ₹0.
Old regime (₹1.5L 80C + ₹50k other): taxable ₹10,25,000 → tax ₹1,20,000 + cess = ₹1,24,800.
Verdict: New regime saves ~₹1.25 lakh. This is why ₹12.75 lakh has become the most talked-about salary figure in India.

Example C — ₹15 lakh salary

New regime: taxable ₹14,25,000 → ₹20,000 + ₹40,000 + ₹33,750 = ₹93,750 + cess = ₹97,500.
Old regime with heavy deductions (₹1.5L 80C + ₹1.8L HRA + ₹50k 80CCD(1B) + ₹25k 80D = ₹4.05L + ₹50k SD): taxable ₹10,45,000 → ₹1,26,000 + cess ≈ ₹1,31,040.
Verdict: Even with ₹4 lakh of deductions, the new regime wins here. The old regime needs roughly ₹4.75–5 lakh of total deductions to compete at this income.

Example D — ₹20 lakh salary, home loan + metro rent profile

New regime: taxable ₹19,25,000 → ₹20,000 + ₹40,000 + ₹60,000 + ₹65,000 = ₹1,85,000 + cess = ₹1,92,400.
Old regime (80C ₹1.5L + home-loan interest ₹2L + 80D ₹25k + NPS ₹50k = ₹4.25L + SD ₹50k): taxable ₹15,25,000 → ₹2,70,000 + cess ≈ ₹2,80,800.
Verdict: New regime by ~₹88,000 even against ₹4.25 lakh of deductions. To flip the result at ₹20 lakh, old-regime deductions would need to exceed roughly ₹8 lakh (e.g. very large HRA in addition to home loan and 80C) — uncommon but possible. This income band is where you must actually calculate, not assume.

Example E — ₹30 lakh salary

New regime: taxable ₹29,25,000 → ₹3,00,000 + (₹5,25,000 × 30%) = ₹4,57,500 + cess = ₹4,75,800.
Old regime (deductions ₹4.25L + SD ₹50k): taxable ₹25,25,000 → ₹5,70,000 + cess ≈ ₹5,92,800.
Verdict: New regime by over ₹1.1 lakh. At higher incomes the new regime's lower slab ladder dominates unless deductions are extraordinary.

6. What the New Income Tax Act, 2025 Means for You

• "Tax Year" replaces AY/PY. FY2026-27 is simply Tax Year 2026-27. No more mental gymnastics converting financial year to assessment year — a genuine simplification for return filing.
• Section numbers change. Familiar references like 87A (rebate) and 80C are renumbered in the new Act. Substance is unchanged; your Form 16 and ITR forms will carry the new references.
• Redesigned, simpler return forms are expected for Tax Year 2026-27 filings (due mid-2027).
• No rate impact. The Act is a re-codification, not a rate change. Your TDS and take-home pay are unaffected by the Act itself.

7. Your FY2026-27 Pre-Planning Checklist (Salaried)

• April–June 2026: Submit your regime declaration to your employer. The new regime is the default — opting for old requires an active declaration. Compare first using the calculator above.
• If choosing old regime: plan 80C early — spreading an ELSS SIP across 12 months beats a panicked March lumpsum, and each instalment starts its own 3-year lock-in clock.
• If choosing new regime: ask whether your employer offers NPS under 80CCD(2) — it is the rare deduction that works in the new regime, up to 14% of basic.
• July 2026: file your FY2025-26 return (due 31 July 2026) — note this return is still under the old 1961 Act's forms.
• December–January: verify your employer's TDS projection against your own calculation; correct any shortfall before Q4 to avoid interest under the advance-tax provisions.
• Investments ≠ deductions. If you moved to the new regime, your goals (retirement, children's education) still need funding — the discipline of a monthly SIP matters regardless of which regime you file under.

Frequently Asked Questions

Did Budget 2026 change anything in my salary tax?

No. Slabs, standard deduction (₹75,000 new / ₹50,000 old), and the rebate all continue unchanged for FY2026-27. The structural change is the new Income Tax Act, 2025 — which changes the law's organisation and forms, not the rates.

Is ₹12.75 lakh really tax-free?

For pure salary income under the new regime, yes: ₹75,000 standard deduction brings ₹12.75 lakh down to ₹12 lakh taxable, on which the computed tax of ₹60,000 is fully offset by the rebate. Capital gains and other special-rate income are outside this rebate.

Can I change my regime after declaring it to my employer?

Yes — the employer declaration only governs TDS. Your final choice is made when filing the return. Salaried taxpayers without business income can switch every year. But a mismatch means excess TDS (refund later) or shortfall (pay with interest), so declare thoughtfully in April.

I live in Hyderabad and pay high rent — does HRA change the answer?

It can. Hyderabad is a 40% HRA city (non-metro classification for HRA purposes). A large HRA exemption combined with a home loan and full 80C can push total old-regime deductions past the breakeven (~₹4.75–5 lakh at ₹15 lakh income; higher at higher incomes). Run both regimes with your actual rent receipts before deciding.
