How this calculator works
What this income tax calculator does
This is a guided income tax calculator for India. It computes your tax under both the Old Regime and the New Regimefor the financial year you choose (FY 2024-25, FY 2025-26, or FY 2026-27), applies the standard deduction, 87A rebate, surcharge and 4% health & education cess, and shows which regime leaves you paying less. Income up to FY 2025-26 is governed by the Income-tax Act, 1961; the Income-tax Act, 2025 applies from FY 2026-27.
Old vs New Regime — the short version
The New Regime (the default since FY 2023-24) has lower slab rates across 7 brackets but removes most deductions. The Old Regime has higher rates but lets you claim 80C, HRA, 80D, NPS, home-loan interest and more. Which one wins depends entirely on how much you can deduct — this calculator works it out from your actual numbers.
Who is this for?
Anyone with Indian income — salaried employees, pensioners, freelancers, and investors. You don't need to know any tax terms; the guided flow asks about your income in plain language and handles the rules for you. For a complete return, capital gains, F&O, presumptive business income and foreign income may need a professional — the calculator flags these.
Is my data safe?
Yes. Every calculation runs in your browser. Nothing you enter — and no Form 16 you upload — is sent to a server or stored. This is an educational tool to help you understand your tax; it does not file your return.
FAQs
What is the difference between the Old and New tax regimes?
The Old Regime lets you claim deductions and exemptions; the New Regime offers lower slab rates but removes most of them. Under the Old Regime you reduce taxable income using 80C, 80D, HRA, home-loan interest and more. The New Regime skips almost all of these in exchange for wider, lower-taxed slabs and a higher standard deduction. This calculator computes both and shows which leaves you paying less.
When were the Old and New tax regimes introduced?
The Old Regime is the long-standing system; the New Regime was introduced in Budget 2020 (effective FY 2020-21). The New Regime was optional at first. In Budget 2023 (effective FY 2023-24) it was made the default, its slabs were widened, and a standard deduction was added. Budget 2025 further revised the New Regime slabs and raised the Section 87A rebate. The Old Regime rates have stayed broadly unchanged throughout.
What happens if I do not choose a regime?
If you do not choose, the New Regime applies automatically — it is the default. Since FY 2023-24, every taxpayer is placed under the New Regime unless they actively opt for the Old Regime. Salaried employees can opt for the Old Regime each year when filing; those with business income must file Form 10-IEA to opt out and can switch back only once. If you never act, you are taxed under the New Regime by default.
Which financial year or assessment year should I select?
Select the financial year in which you earned the income you are filing for. The financial year (FY) is the earning year; the assessment year (AY) is the following year when you file and it is assessed — AY is always FY plus one. For example, income earned in FY 2024-25 is filed in AY 2025-26. This calculator labels both so you can match whichever your ITR form or documents use.
Can I switch between Old and New Regime every year?
Yes, salaried employees can switch every year. Inform your employer before the start of the financial year. Self-employed individuals can only switch once in their lifetime.
Is New Regime always better?
Not always. If your total deductions (HRA + 80C + 80D + home loan) exceed approximately ₹5 lakh, Old Regime may save more. The breakeven depends on your income level. Use this calculator to compare with your actual numbers.
Do I need to file ITR if my income is below ₹12 lakh?
Possibly yes — ₹12 lakh is the zero-tax rebate limit, not the filing trigger. The Section 87A rebate can make tax nil up to ₹12 lakh (New Regime), but the obligation to file is set by the basic exemption limit (₹4 lakh New / ₹2.5 lakh Old). You must also file if your employer deducted TDS and you want a refund, or if you have capital gains, foreign income, or income from multiple sources.
What are the ITR filing deadlines?
For AY 2026-27 (income earned in FY 2025-26), July 31, 2026 for most individuals. This covers ITR-1 and ITR-2. Business income (ITR-3, ITR-4, non-audit) has a deadline of August 31, 2026. If a tax audit is required, the deadline is October 31, 2026.
What happens if I miss the ITR deadline?
You will pay a late filing penalty of ₹5,000 under Section 234F. If your income is below ₹5 lakh, the penalty is reduced to ₹1,000. You also lose the ability to carry forward capital losses to future years.
Can NRIs claim the 87A rebate?
No, Section 87A rebate is only for resident individuals. Non-residents cannot claim this benefit under either the Old or New tax regime.
