How Your Tax is Calculated

The Indian Income Tax system provides two taxation regimes for individuals: the Old Tax Regime and the New Tax Regime. Below is a detailed explanation of how tax is calculated in both regimes, including considerations for financial year, income slabs, deductions, exemptions, and age-based categories.

1. Understanding the Financial Year

The financial year in India starts from 1st April of a year and ends on 31st March of the following year. For example, the financial year 2024-25 runs from 1st April 2024 to 31st March 2025. Your income earned during this period will be assessed in the assessment year 2025-26, when you file your tax returns.

2. Old Tax Regime

The Old Tax Regime allows individuals to claim various deductions and exemptions to reduce their taxable income. Here’s how it works:

  • Income Slabs: Tax is calculated based on predefined income slabs. The higher your income, the higher the rate of tax.
  • Deductions: You can reduce your taxable income by claiming deductions under sections such as:
    • Section 80C: Investments like EPF, PPF, ELSS, and life insurance premiums can reduce your taxable income up to ₹1,50,000.
    • Section 80D: Medical insurance premiums for self and family can provide an additional deduction of ₹25,000 to ₹50,000.
    • HRA: House Rent Allowance, if applicable, can reduce taxable income.
  • Age-Based Slabs: Senior citizens (60–80 years) and super senior citizens (above 80 years) enjoy higher exemption limits.

After applying deductions, your taxable income is calculated, and the tax is applied as per the slab rates. For example, if your taxable income is ₹7,00,000, you will pay:

  • 5% on income between ₹2,50,001 and ₹5,00,000
  • 20% on income between ₹5,00,001 and ₹7,00,000

3. New Tax Regime

The New Tax Regime introduced lower tax rates but removed most exemptions and deductions. Here’s how it works:

  • Income Slabs: Tax is calculated based on new slab rates. For instance:
    • 0% tax for income up to ₹3,00,000
    • 5% tax for income between ₹3,00,001 and ₹6,00,000
    • 10% tax for income between ₹6,00,001 and ₹9,00,000
    • 15% tax for income between ₹9,00,001 and ₹12,00,000
    • 20% tax for income between ₹12,00,001 and ₹15,00,000
    • 30% tax for income above ₹15,00,000
  • No Deductions: Under this regime, exemptions like HRA and deductions under 80C, 80D, etc., are not available. However, a standard deduction of ₹50,000 is allowed.
  • Simplicity: This regime is beneficial for individuals who do not have significant investments or eligible deductions.

4. Age-Based Categories

Age plays a significant role in determining the tax liability. The three categories are:

  • Below 60 years: Standard slab rates apply.
  • Senior Citizens (60–80 years): Higher exemption limits in the old regime (₹3,00,000 instead of ₹2,50,000).
  • Super Senior Citizens (Above 80 years): Highest exemption limits in the old regime (₹5,00,000).

5. Choosing the Right Regime

Deciding between the old and new tax regimes depends on your income, investments, and eligible deductions. Use the following criteria:

  • Old Regime: Suitable if you have significant investments and can claim deductions.
  • New Regime: Beneficial if you have minimal or no deductions and prefer lower tax rates.

6. Calculation Example

Let’s take an example to compare the two regimes:

  • Income: ₹10,00,000
  • Deductions: ₹1,50,000 under Section 80C (only for the old regime)

Under the Old Regime:

  • Taxable Income = ₹10,00,000 - ₹1,50,000 = ₹8,50,000
  • Tax: ₹12,500 (5% of ₹2,50,000) + ₹70,000 (20% of ₹3,50,000) = ₹82,500
Under the New Regime:
  • Taxable Income = ₹10,00,000
  • Tax: ₹7,500 (5% of ₹1,50,000) + ₹15,000 (10% of ₹1,50,000) + ₹30,000 (15% of ₹2,00,000) = ₹52,500
In this case, the new regime results in lower tax liability.
