The calculator captures all taxable and non-taxable components:

Basic Salary: Foundation of your pay structure
HRA: House Rent Allowance (partially exempt)
Special Allowance: Fully taxable

Calculate HRA Exemption Automatically

🏠 HRA Calculation Logic:

HRA exemption is the MINIMUM of three values:

Option 1: Actual HRA Received

Total HRA paid by employer in a year

Option 2: Rent – 10% of Basic

Rent paid minus 10% of your basic salary

Option 3: 50% or 40% of Basic

50% if metro (Mumbai, Delhi, Kolkata, Chennai), else 40%

📊 Example Calculation:

Basic Salary: ₹50,000/month (₹6L/year)
HRA Received: ₹20,000/month (₹2.4L/year)
Rent Paid: ₹15,000/month (₹1.8L/year)
City: Mumbai (Metro)
Option 1: ₹2,40,000
Option 2: ₹1,80,000 – ₹60,000 = ₹1,20,000
Option 3: 50% of ₹6L = ₹3,00,000
Exemption: ₹1,20,000 (Minimum)
4

Apply All Tax Deductions (80C, 80D, etc.)

💸 Chapter VI-A Deductions:

Section 80C: PPF, ELSS, EPF, etc. ₹1,50,000

Section 80D: Health Insurance ₹1,00,000
Section 80E: Education Loan No Limit
Section 80G: Donations Variable
Maximum Possible: ₹3,00,000+

🎯 Standard Deduction:

Old Regime

✓ Allows all deductions (80C, 80D, HRA, etc.)

New Regime

✓ Best if you have minimal deductions

🎯 Recommendation Logic:

Old Regime Tax: ₹1,22,200
New Regime Tax: ₹1,64,000
✅ Old Regime Saves: ₹41,800

The calculator automatically highlights the regime that saves you more money with a green checkmark ✅

7

🔍 Validation Checks:

The calculator automatically detects these issues:

⚠️ TDS Mismatch: If TDS deducted ≠ calculated tax
⚠️ Excess TDS: You may be eligible for refund
⚠️ Short TDS: You may need to pay additional tax
✓ Professional Tax: Verified by state

📋 Validation Example:

Calculated Tax: ₹1,22,200
TDS Deducted (Form 16): ₹1,15,000
Discrepancy: ₹7,200 Short

⚠️ Action Needed:

You need to pay ₹7,200 additional tax while filing ITR
