📐 Tax Calculation Logic
Old Regime:
- 1️⃣ Gross Income – Deductions = Taxable Income
- 2️⃣ Apply age-based slabs (₹2.5L/₹3L/₹5L exemption)
- 3️⃣ Calculate slab-wise tax (5%, 20%, 30%)
- 4️⃣ Apply 87A rebate if income ≤ ₹5L
- 5️⃣ Add 4% Health & Education Cess
New Regime:
- 1️⃣ Gross Income – ₹75K Standard Deduction
- 2️⃣ Apply 7-tier slabs (0% to 30%)
- 3️⃣ Calculate slab-wise tax
- 4️⃣ Apply 87A rebate if income ≤ ₹12L
- 5️⃣ Add 4% Health & Education Cess
Note: Section 87A rebate makes tax zero for incomes up to ₹5L (Old) or ₹12L (New). Cess is calculated on tax amount, not income.
