Income Tax Calculator Formulas

1. Gross Total Income

Gross Total Income = Annual Gross Income + Other Taxable Income

2. Total Deductions

Total Deductions = Standard Deduction + Other Eligible Deductions

3. Taxable Income

Taxable Income = max(0, Gross Total Income − Total Deductions)

4. Slab Tax

Slab Tax = Tax from each applicable income-tax slab added together

5. Section 87A Rebate

Tax After Rebate = max(0, Tax Before Rebate − Eligible 87A Rebate)

6. Surcharge

Surcharge = Applicable Surcharge Rate × Tax After Rebate

7. Health & Education Cess

Cess = 4% × (Tax After Rebate + Surcharge)

8. Final Estimated Tax

Final Tax = Tax After Rebate + Surcharge + Cess

9. Effective Tax Rate

Effective Tax Rate = (Final Tax ÷ Gross Total Income) × 100

10. Income After Estimated Tax

Income After Tax = Gross Total Income − Final Tax

How to Calculate Income Tax – Step by Step

Step 1 — Enter annual income.
Example: ₹12,00,000 annual income.
Step 2 — Select the tax regime.
Choose either the New Tax Regime or Old Tax Regime.
Step 3 — Apply standard deduction.
The applicable standard deduction is considered for eligible salary/pension income.
Step 4 — Calculate taxable income.
Gross income is reduced by applicable deductions.
Step 5 — Apply tax slabs.
The taxable income is divided across the applicable tax slabs. Each slab is taxed at its applicable rate.
Step 6 — Apply Section 87A rebate.
If the taxpayer satisfies the applicable conditions, eligible rebate is deducted from income tax.
Step 7 — Calculate surcharge.
Surcharge may apply when taxable income crosses specified thresholds.
Step 8 — Add Health & Education Cess.
The calculator applies 4% cess to applicable income tax and surcharge.
Step 9 — Display final result.
The calculator shows estimated tax, effective tax rate and income remaining after estimated income tax.

Example: ₹12 Lakh Income Under New Regime

Suppose an eligible resident individual has salary income of ₹12,00,000 for FY 2025-26.

  1. Gross salary = ₹12,00,000
  2. New-regime standard deduction = ₹75,000
  3. Taxable income = ₹12,00,000 − ₹75,000 = ₹11,25,000
  4. Applicable tax slabs are then applied.
  5. The eligible Section 87A rebate is considered.
  6. Applicable cess is then calculated.

This illustrates why a calculator must consider deductions and rebates instead of simply multiplying total salary by a single tax rate.

Health & Education Cess is calculated at 4% of applicable income tax plus surcharge.

Which is better: Old or New Tax Regime?

It depends on your income, deductions, exemptions and financial circumstances. Use the comparison feature above to estimate both regimes.

Does age affect income tax?

Age can affect the basic exemption structure under the Old Tax Regime. The New Tax Regime does not use the same age-based slab structure.

Does this calculate my exact salary take-home?

No. The result is an income-tax estimate. Actual salary credited to your bank account may also be affected by EPF, professional tax, insurance, employer deductions, TDS adjustments and other payroll items.

Is this an official government calculator?

No. This is an independent calculator for estimation and educational purposes. Always verify the final liability against the applicable law and official Income Tax Department resources.

Can this calculator calculate capital gains?

Not comprehensively. Capital gains and other special-rate income can have separate tax rules. A professional-grade calculator should calculate those categories separately.
