New tax regime slabs for FY 2026-27
The new regime is the default. Budget 2026 kept the slabs unchanged. Salaried taxpayers get a standard deduction of ₹75,000, and a rebate makes taxable income up to ₹12 lakh tax-free.
| Taxable income | Rate |
|---|---|
| ₹0 – ₹4 L | Nil |
| ₹4 L – ₹8 L | 5% |
| ₹8 L – ₹12 L | 10% |
| ₹12 L – ₹16 L | 15% |
| ₹16 L – ₹20 L | 20% |
| ₹20 L – ₹24 L | 25% |
| Above ₹24 L | 30% |
Old tax regime slabs
The old regime has higher rates but lets you claim deductions such as 80C, 80D, HRA and home loan interest. The standard deduction is ₹50,000 and the rebate covers taxable income up to ₹5 lakh.
| Taxable income | Below 60 | 60 to 79 | 80 and above |
|---|---|---|---|
| ₹0 – ₹2.5 L | Nil | Nil | Nil |
| ₹2.5 L – ₹3 L | 5% | Nil | Nil |
| ₹3 L – ₹5 L | 5% | 5% | Nil |
| ₹5 L – ₹10 L | 20% | 20% | 20% |
| Above ₹10 L | 30% | 30% | 30% |
Worked example: ₹18 lakh salary, new regime
- Gross salary: ₹18,00,000
- Less standard deduction: ₹75,000
- Taxable income: ₹17,25,000
- ₹0 – ₹4 L at 0%: ₹0
- ₹4 L – ₹8 L at 5%: ₹20,000
- ₹8 L – ₹12 L at 10%: ₹40,000
- ₹12 L – ₹16 L at 15%: ₹60,000
- ₹16 L – ₹20 L at 20%: ₹25,000
- Cess at 4%: ₹5,800
- Total tax: ₹1,50,800 (₹12,567 a month)
Old vs new regime at common salaries
Assuming full 80C (₹1.5 lakh), ₹25,000 health insurance and ₹2,500 professional tax in the old regime, and no other income:

Frequently asked questions
What are the income tax slabs for FY 2026-27?
Under the new regime: nil up to ₹4 lakh, 5% for ₹4–8 lakh, 10% for ₹8–12 lakh, 15% for ₹12–16 lakh, 20% for ₹16–20 lakh, 25% for ₹20–24 lakh and 30% above ₹24 lakh. Budget 2026 did not change these slabs. The old regime keeps its slabs of nil up to ₹2.5 lakh, 5% up to ₹5 lakh, 20% up to ₹10 lakh and 30% above.
Is income up to ₹12 lakh tax-free in the new regime?
Yes, for resident individuals. A rebate of up to ₹60,000 wipes out the tax when taxable income is ₹12 lakh or less. Salaried people also get a ₹75,000 standard deduction, so a salary of up to ₹12.75 lakh pays no tax. The rebate does not cover special-rate income such as capital gains.
What happens if my income is just above ₹12 lakh?
Marginal relief applies: the tax you pay cannot be more than the amount by which your taxable income exceeds ₹12 lakh. So at ₹12.1 lakh you pay at most ₹10,000 plus cess, not the full slab tax of ₹61,500.
Which is better, the old or the new tax regime?
For most people the new regime is cheaper because of its lower rates and the ₹12 lakh rebate. The old regime wins only if you claim large deductions, such as full 80C, health insurance, HRA and home loan interest. The calculator shows the exact deductions you would need for the old regime to come out ahead.
Which deductions are allowed in the new regime?
The new regime allows the ₹75,000 standard deduction for salaried people, the employer's contribution to NPS and a few others, but not 80C, 80D, HRA, home loan interest on a self-occupied house or professional tax.
Is the new regime the default?
Yes. The new regime applies unless you choose the old one. Salaried employees can pick a regime each year; people with business income have limited chances to switch back and forth.
What is the Income-tax Act, 2025?
It replaces the Income-tax Act, 1961 from 1 April 2026. It uses a single 'tax year' in place of the previous year and assessment year, and renumbers sections (the 87A rebate is now Section 156). The tax rates for 2026-27 are the same as in 2025-26.
How are surcharge and cess calculated?
A surcharge of 10% applies above ₹50 lakh, 15% above ₹1 crore and 25% above ₹2 crore. Above ₹5 crore it is 37% in the old regime but capped at 25% in the new regime. A 4% health and education cess is then added to tax plus surcharge.
