What is the New vs Old Tax Calculator?
Compare modeled old- and new-regime salary tax for FY 2025-26 / AY 2026-27. This comparison does not choose a regime for you or assess every available deduction.
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.
