How the income-tax estimate is built
This calculator applies labelled Indian slab logic for a stated financial year and regime. It is a planning estimate. Notifications, cess, surcharge, and rebate sections change; the on-page date tells you which snapshot was coded.
What you must still verify
Slab rates, the standard deduction, rebate under section 87A, and surcharge thresholds are set by statute and the Finance Act for a year. Toolioz copies those into code after a review pass. If Parliament or the CBDT later changes a figure, the official portal wins. Compare the result with the department calculator or a CA before filing.
Old versus new regime is not a slogan. Deductions such as 80C, 80D, and HRA exemptions exist in the old regime and are largely unavailable in the new regime except for a short listed set. The comparison is only as good as the deduction amounts you enter. Leaving 80C at zero while claiming "old regime is worse" is a data-entry error, not tax law.
Salary is not the same as taxable income
CTC includes employer PF, gratuity accruals, and sometimes variable pay that is taxed only when received. This page uses the income figure you type. Professional tax, employer NPS, and exempt allowances need to be reflected in that figure or in the deduction fields. Agricultural income, capital gains, and business heads are not a full ITR substitute here.
Worked examples
Rebate intuition
If the coded year includes a rebate that zeros tax up to a stated taxable-income cap, a salary just below that cap can show zero tax while a salary slightly above it does not. That cliff is in the statute, not a glitch. Read the rebate section on the department site for the exact cap in force.
Limits of this page
- Not a filing engine: no AIS import, no Form 16 parser on this page.
- Surcharge, marginal relief, and some special rates may be simplified.
- State professional tax is not a full India-wide matrix.
