✅ Basic Concepts:

🔸 AY 2025-26 = Financial Year 2024-25

Income earned from 1st April 2024 to 31st March 2025 is filed as ITR in AY 2025-26.

🔸 Income Tax Regimes

There are two regimes:

Old Tax Regime – You can claim deductions like:
- Standard Deduction (₹50,000)
- HRA
- 80C (₹1.5L for LIC, PPF, PF, etc.)
- 80D (Medical Insurance)
- 24(b) (Home Loan Interest)
- LTA, etc.
New Tax Regime (default from FY 2023-24)
- Lower tax rates
- Fewer deductions allowed
- ₹50,000 standard deduction allowed from FY 2023-24 onwards.

₹12,00,001 – ₹15,00,000	20%

Rebate under Section 87A up to income of ₹7L ⇒ No tax (after rebate).
Standard deduction of ₹50,000 is available.

🔹 Old Regime:

Income Range	Tax Rate
Up to ₹2,50,000	Nil
₹2,50,001 – ₹5,00,000	5%

📊 Examples: Salaried Individuals

👤 1. Salary = ₹5,00,000

📌 Old Regime:

Gross Income: ₹5,00,000
Less: Standard Deduction = ₹50,000
Net Taxable: ₹4,50,000
Tax before rebate = 5% of ₹2,00,000 = ₹10,000
87A rebate = ₹10,000 ⇒ Tax = ₹0

✅ Best regime: Old Regime (same as new in this case)

👤 2. Salary = ₹10,00,000

A) 📌 New Regime

Salary = ₹10,00,000
Less Standard Deduction = ₹50,000
Taxable = ₹9,50,000

Tax Calculation:

Slab	Tax
0–3L	₹0
3–6L (3L) @ 5%	₹15,000

Total Tax = ₹54,600

B) 📌 Old Regime

HRA/Other = ₹25,000
Std Deduction = ₹50,000
Total Deductions = ₹2.5L
Gross: ₹10L
Taxable = ₹7.5L

Tax Calculation:

Up to ₹2.5L = Nil
₹2.5L – ₹5L = 5% = ₹12,500
₹5L – ₹7.5L = 20% = ₹50,000
Total = ₹62,500 + 4% cess = ₹65,000

👉 New Regime wins (₹54,600 < ₹65,000)
