Method

Old taxable income = max(0,salary+other income−₹50,000−old deductions); new taxable income = max(0,salary+other income−₹75,000−new deductions). Old slab rates on successive taxable bands are 0% to ₹2.5 lakh, 5% to ₹5 lakh, 20% to ₹10 lakh and 30% above. New rates are 0% to ₹4 lakh, then 5%, 10%, 15%, 20% and 25% on successive ₹4 lakh bands through ₹24 lakh, and 30% above. Sum tax within each band. Old rebate = min(slab tax,₹12,500) if taxable income ≤₹5 lakh; new rebate = min(slab tax,₹60,000) if taxable income ≤₹12 lakh. Above ₹12 lakh, new-regime marginal relief = max(0,slab tax−(taxable income−₹12 lakh)). Final tax = 1.04 × max(0,slab tax−rebate−applicable relief). Difference = absolute difference between regime totals.

How this calculation works

Compare ordinary salary-income tax under the site’s scoped Tax Year 2026–27 old- and new-regime rules. Start with annual salary, add other ordinary income and enter only deductions allowed for the relevant regime. Unlike the salary calculator, this form does not unpack CTC, PF or HRA, and the output is annual tax rather than take-home pay.

Old taxable income = max(0,salary+other income−₹50,000−old deductions); new taxable income = max(0,salary+other income−₹75,000−new deductions). Old slab rates on successive taxable bands are 0% to ₹2.5 lakh, 5% to ₹5 lakh, 20% to ₹10 lakh and 30% above. New rates are 0% to ₹4 lakh, then 5%, 10%, 15%, 20% and 25% on successive ₹4 lakh bands through ₹24 lakh, and 30% above. Sum tax within each band. Old rebate = min(slab tax,₹12,500) if taxable income ≤₹5 lakh; new rebate = min(slab tax,₹60,000) if taxable income ≤₹12 lakh. Above ₹12 lakh, new-regime marginal relief = max(0,slab tax−(taxable income−₹12 lakh)). Final tax = 1.04 × max(0,slab tax−rebate−applicable relief). Difference = absolute difference between regime totals.

Worked example

This example uses illustrative inputs. Your current result is shown above.

For annual salary ₹15,00,000, no other income, old deductions ₹1,50,000 and new deductions ₹0, old taxable income is ₹13,00,000 and new taxable income is ₹14,25,000. Old slab tax ₹2,02,500 plus 4% cess gives ₹2,10,600. New slab tax ₹93,750 plus cess gives ₹97,500, lower by ₹1,13,100.

Assumptions and limits

  • The existing Tax Year 2026–27 model is for ordinary salary income; its old-regime basic slab is the under-60 slab.
  • Both regimes must remain within ₹50 lakh taxable income; surcharge and special-rate income are excluded.
  • Standard salary deductions are automatic. Do not include them again in the deduction inputs; eligibility for other entered deductions is not checked.

Questions people ask

Should I enter CTC as annual salary?

Use the salary amount relevant to this simplified tax calculation, not an unadjusted CTC that contains employer PF, gratuity or non-cash components. The salary calculator can show that CTC-to-cash breakdown.

Is new-regime deductions a general investment allowance?

No. Enter only an amount eligible under that regime for your situation. Copying old-regime deductions into this field can understate tax because the form does not validate their legal basis.

Can the result be used for a tax return with capital gains?

Not as a complete filing calculation. Special-rate income, surcharge, losses, credits and other filing adjustments require the appropriate official computation.
