# Income Tax Calculator: Plan Your Savings and Maximize Your Take-Home Pay

Are you confused between the Old Tax Regime and the New Tax Regime? Determining which one will save you more money can feel like a math puzzle every financial year. That is where a reliable Income Tax Calculator becomes your best friend.

In this guide, we break down how the Indian income tax system works, the critical differences between the new vs old regime, and how you can use the ToolPilot Income Tax Calculator to make an informed decision in seconds.

Understanding the Indian Income Tax Structure

Income tax in India is calculated based on slabs. Depending on your total taxable income, different percentages of tax are applied to different portions of your earnings. Your "taxable income" is not necessarily your gross salary — it is gross income minus exemptions and deductions.

New vs Old Tax Regime: Which One Should You Choose?

This is the most common question taxpayers ask. The new tax regime is now the default — if you do not actively choose the old regime, your employer deducts tax under the new regime automatically. Let's compare them simply.

The Old Tax Regime

The Old Regime is designed for those who actively save and invest. It allows you to reduce your taxable income through various deductions:

• Section 80C: Up to ₹1.5 lakh for PPF, ELSS, LIC, and school fees
• Section 80D: Deductions for health insurance premiums
• HRA (House Rent Allowance): For those living in rented accommodation
• Home Loan Interest: Deductions on principal and interest

Best for: People with high investments, home loans, and significant insurance premiums.

The New Tax Regime (Default)

The New Regime offers lower slab rates but removes almost all the exemptions and deductions mentioned above. The goal is simplicity — no more hunting for investment proofs.

Best for: Those who prefer higher cash-in-hand and do not want to manage multiple tax-saving investments.

FAQs: Income Tax Calculation in India

Which regime is better for a salary of ₹10 Lakh?

It depends on your investments. If you have deductions exceeding ₹2.5–3 lakh (HRA + 80C + 80D), the Old Regime might be better. Otherwise, the New Regime usually offers a lower tax burden for this bracket.

Can I switch between regimes every year?

Yes, salaried employees can choose between the old and new regimes every year at the time of filing their returns. However, those with business income can typically only switch once in their lifetime.

Is the Income Tax Calculator free to use?

Yes, the ToolPilot Income Tax Calculator is 100% free, requires no signup, and processes all your data locally in your browser for maximum privacy.

What is the standard deduction?

The standard deduction is ₹75,000 for salaried employees under the new regime for FY 2025-26, and it applies to both regimes for salaried individuals.
