What is the Income Tax Calculator?
A salary-only illustration for FY 2025-26 / AY 2026-27, using resident under-60 slab and rebate assumptions. It is not a return-filing engine or a determination of deduction eligibility.
How does it work?
The model applies the selected regime's salary standard deduction, slab tax, supported rebate, surcharge marginal relief and cess. Old-regime fields accept already-eligible deductions with the displayed ceilings. HRA is an entered exemption; this tool does not compute it from salary and rent. New-regime employer NPS deductions and other special deductions are not collected or modeled. Rental income, house-property losses, special-rate income and age/residency variations are outside scope.
Worked example
With gross salary of Rs 15,00,000 and no additional deductions, modeled new-regime tax is Rs 97,500 including cess: taxable salary is Rs 14,25,000 after the Rs 75,000 standard deduction. This example is for the stated year and salary-only assumptions.
When to use this calculator
- 1Compare supported salary scenarios for the stated fiscal year.
- 2Check how an already-verified eligible deduction changes the modeled old-regime amount.
Common mistakes to avoid
- ✕Entering CTC rather than the gross salary-income amount relevant to the model.
- ✕Entering premiums, rent or the full joint-loan payment as though they were automatically eligible deductions.
- ✕Double-counting a payment across fields or assuming a lower estimate is a regime recommendation.
- ✕Using this model for rental income, capital gains, a later fiscal year or a full filing calculation.
Frequently asked questions
- Does the calculator establish eligibility?
- No. Section 80D has separate self/family and parent limits. Enter the eligible amount after checking age, payment and coverage conditions. Co-owner home-loan amounts must be your eligible share. The model cannot verify these facts.
- Does the new-regime comparison include every deduction?
- No. It includes the salary standard deduction but does not accept employer NPS contributions or other special deductions. A lower modeled amount is not necessarily your final liability.
- Where can I check the rules?
- The linked Income Tax Department AY 2026-27 guidance is the source for the supported salary slabs and deduction boundaries. Filing eligibility and deadlines require separate review.
