What Is an Income Tax Calculator?

BizPillar’s Income Tax Calculator is a smart online tool that instantly estimates your tax liability based on your income, deductions, and the latest tax rules. No more confusing spreadsheets — just fast, accurate numbers.

Why It Matters

Tax rules change often, and manual calculations are a headache. Our calculator cuts through the complexity, giving you a clear picture of how much tax you owe (or save) in seconds.

Who Is It For?

  • New taxpayers who find slabs and deductions overwhelming

  • Salaried individuals comparing Old vs. New Regime

  • Freelancers, founders, and business owners checking advance tax

Best Time to Use It

  • Before filing your ITR

  • While planning tax-saving investments

  • When deciding whether to switch tax regimes

How Income Tax Works

Income Tax = (Gross Income – Deductions) × Tax Rate – Rebates + Cess

Quick breakdown:

  • Gross Income: Salary, business income, property income, gains, etc.

  • Deductions: 80C–80U (PPF, NPS, insurance, home loan interest, and more)

  • Tax Rate: Based on Old or New Regime

  • Rebate: Section 87A (income up to ₹7 lakh under the New Regime = zero tax)

  • Cess: Additional 4%

Example (Income: ₹10,00,000 | Deductions: ₹1,50,000)

Old Regime: ₹85,800
New Regime: ₹41,600

>>New Regime wins here.
