Before deductions and standard deduction.
Deductions (old regime only)
These only reduce tax under the old regime. The new regime ignores them.
New regime wins for you
The new regime is cheaper for you, even before any deductions. You save ₹42,900.
Old regime tax
₹1,40,400
Taxable income ₹10,75,000

Old regime breakdown
New regime breakdown
Estimated using FY 2026-27 slabs. Surcharge (income above ₹50 lakh) and marginal relief are not included. Slabs confirmed against the official Income Tax portal. Verify with a tax professional before filing.
How it works
Taxable income = gross − standard deduction − allowed deductions. Slab tax + 4% cess, with 87A rebate up to ₹60,000 (new regime, taxable ≤ ₹12L).
Example: ₹15L salary, new regime → taxable ₹14.25L → tax ₹97,500.

When to Use This Calculator
Use the income tax calculator during salary review season and before filing, when the old and new regimes leave most salaried employees unsure which one leaves more money in hand. Enter your annual income, deductions like 80C, 80D and NPS, and the home loan interest you claim, and the tool computes the tax under both regimes for the current financial years, with the standard deduction and rebate applied automatically. The comparison card shows the tax due under each regime, so the choice stops being a guess. Employees switching jobs mid-year, freelancers estimating advance tax, and anyone planning an NPS or PPF contribution before 31 March use it to see how each decision changes the final liability. Re-run it whenever your income or deductions change.
How to Use This Calculator
- Step 1: Select the financial year, such as FY 2026-27, and your age group.
- Step 2: Enter your gross annual salary before any deductions.
- Step 3: Under the old regime section, enter your deduction amounts for 80C, 80D and 24(b) home loan interest, since these do not apply under the new regime.
- Step 4: Read the tax under both regimes, the slab-by-slab breakdown and the verdict showing which regime saves more.
Worked Example
A salaried employee aged 32 in Bengaluru earns ₹15,00,000 in FY 2026-27. Select FY 2026-27 and the under-60 age group, and enter 1500000 as gross income. Under the old regime, add ₹1,50,000 for 80C, ₹25,000 for 80D and ₹2,00,000 for 24(b) home loan interest. The calculator shows about ₹1,40,400 of tax under the old regime and about ₹97,500 under the new regime, so the new regime saves about ₹42,900 for this income and deduction pattern.
Tips and Common Mistakes
- •Tip 1: The new regime has a ₹75,000 standard deduction for salaried taxpayers, while the old regime allows it only along with 80C and other deductions.
- •Tip 2: Recalculate in the year your loan EMIs end or your 80C usage changes, because the cheaper regime can flip as deductions change.
- •Tip 3: Tax is computed on slabs, not on the whole income, so the slab breakdown the calculator shows is the correct way to read the result.
- ✗Mistake 1: Entering the same deduction amounts for both regimes; the new regime ignores 80C, 80D and 24(b) entirely.
- ✗Mistake 2: Forgetting that surcharge applies above ₹50 lakh income, which this estimate does not include.
Old Regime vs New Regime for a ₹15 Lakh Salary
| Item | Value |
|---|---|
| Tax under the new regime | Nil, because total income stays under the ₹12,00,000 rebate ceiling |
| Tax under the old regime | About ₹58,000 after the ₹50,000 standard deduction |
| Which to choose | The new regime, unless you have large claims under Section 80C |
| Section 80C cap | ₹1,50,000 per year under the old regime |
| Section 80D cap | ₹25,000 for self and family under the old regime |
What this figure assumes
Figures follow the new regime slab tables for the stated assessment year, with Section 87A rebate applied where total income falls under the rebate ceiling. It does not compute the old regime, perquisites, clubbed income, capital gains or advance tax liability, and it is not a substitute for filing a return.

Frequently Asked Questions
Which tax regime is better for me?
It depends on your income and how many deductions you claim. If you claim deductions like 80C, 80D and 24(b) that add up, the old regime can be cheaper. Otherwise the new regime's lower slab rates usually win. This calculator compares both side by side.
What are the new regime tax slabs for FY 2026-27?
The slabs are: up to ₹4L nil, ₹4–8L at 5%, ₹8–12L at 10%, ₹12–16L at 15%, ₹16–20L at 20%, ₹20–24L at 25% and above ₹24L at 30%. A ₹75,000 standard deduction applies, and the ₹60,000 rebate under section 87A makes income up to ₹12L effectively tax-free.
Is income up to ₹12 lakh really tax-free?
Under the new regime, yes. The ₹60,000 rebate under section 87A cancels the tax for taxable income up to ₹12L. Your gross salary can be up to ₹12.75L because of the ₹75,000 standard deduction.
Do the old and new regime give the same standard deduction?
No. The new regime gives ₹75,000 and the old regime gives ₹50,000. The old regime also allows deductions such as 80C, 80D and home loan interest under 24(b), which the new regime does not.
Does this calculator include cess and surcharge?
It includes the 4% health and education cess. Surcharge for incomes above ₹50 lakh and marginal relief are not included, so very high earners should check the full calculation with a professional.
