2. Tax Calculation Logic

  • For Old Regime: It applies slab-wise rates, standard deductions, and senior citizen benefits.
  • For New Regime: Slab-based rates are used without major deductions.

3. Surcharge and Cess Addition

Applicable surcharge rates (10% to 37%) and cess (4%) are added to the computed tax.

4. Rebate Under Section 87A

If eligible, rebates are applied to reduce liability.

5. Final Comparison

Both calculations are displayed with a clear message like:

“You save ₹15,000 by choosing the New Tax Regime.”

✅ Example Use Case

Let’s say you’re a 35-year-old salaried individual earning ₹9,00,000 annually with ₹1.5 lakh deductions.

  • Old Regime Tax: ₹33,800 (post deductions and rebates)
  • New Regime Tax: ₹39,000
