How is Income Tax Calculated?
Income tax is generally calculated using the following steps:
- Calculate your Gross Annual Income.
- Add income from all eligible sources.
- Deduct eligible exemptions and deductions (Old Regime).
- Calculate Taxable Income.
- Apply the applicable tax slab rates.
- Add surcharge and cess (if applicable).
- Arrive at the final tax payable.
Using an Income Tax Calculator automates these steps and provides accurate results within seconds.
Understanding the Old Tax Regime
The Old Tax Regime allows taxpayers to reduce taxable income by claiming various deductions and exemptions.
Some common deductions include:
- Section 80C investments
- Health insurance premiums (Section 80D)
- Home loan interest
- House Rent Allowance (HRA)
- Leave Travel Allowance (LTA)
- National Pension System (NPS) deductions
- Standard Deduction (as applicable)
This regime is generally suitable for individuals who invest regularly and claim multiple deductions.
Understanding the New Tax Regime
The New Tax Regime offers lower tax rates but removes most deductions and exemptions.
Instead of investing to reduce taxable income, taxpayers pay tax according to simplified slab rates.
It is often preferred by:
- Salaried employees with few deductions
- Young professionals
- Individuals who prefer simpler tax filing
- Taxpayers without major investments
Old Tax Regime vs New Tax Regime
| Feature | Old Tax Regime | New Tax Regime |
|---|---|---|
| Tax Rates | Higher | Lower |
| Deductions Allowed | Yes | Mostly No |
| Exemptions | Available | Limited |
| Investment Benefits | Yes | Minimal |
| Filing Simplicity | Moderate | Easy |
| Best For | High deductions | Low deductions |
Example 1: Income Tax Calculation (Old Regime)
Suppose your annual salary is:
- ₹10,00,000
Eligible deductions:
- Section 80C: ₹1,50,000
- Health Insurance: ₹25,000
- Standard Deduction: Applicable
After deductions, your taxable income reduces significantly, resulting in lower tax liability.
Example 2: Income Tax Calculation (New Regime)
Annual Income:
- ₹10,00,000
Since most deductions are unavailable, tax is calculated directly using the applicable slab rates.
Although tax rates are lower, individuals with significant deductions may find the Old Regime more beneficial.
