Income Tax Calculator

Estimate annual tax using old and new regime with standard deduction and cess.

What This Income Tax Calculator Does

This page helps estimate annual income tax for individuals who want a fast comparison between the old and new regime using salary income, other income, deductions, standard deduction, and cess. It is meant for planning, not for filing directly. The real advantage is that it lets you compare the effect of deductions before the final return process begins.

Note that in India, cryptocurrency and virtual digital asset (VDA) income is taxed separately under Section 115BBH at a flat 30% rate (+ 4% cess and 1% TDS) and cannot be offset against business or salary deductions. To calculate your digital asset tax liabilities specifically, use our dedicated Crypto Tax Calculator.

How To Calculate Income Tax Step by Step

Enter salary income and any other income, then choose the regime you want to test. After that, add deductions such as 80C and other eligible items. The calculator first works out gross income, applies the relevant deduction logic, computes taxable income, estimates slab-based tax, and finally adds 4% cess. The effective tax rate then helps you judge how much of your annual income is being consumed by tax.

Example Comparison

If a salaried taxpayer earns Rs 12,00,000 and claims meaningful deductions, the old regime may become more attractive than it first appears. Key deductions often include Section 80C investments like ELSS mutual funds (which you can forecast with our SIP Calculator) and housing loan interest under Section 24b (which you can calculate with our Home Loan EMI Calculator). If deductions are low or absent, the new regime can produce a cleaner outcome.

How To Use The Output Better

• Test both regimes before making payroll or year-end planning choices.
• Check whether deductions are truly available before relying on them.
• Use the effective tax rate to estimate monthly tax reserve needs.
• Review surcharge, rebate, and special cases separately if your income is more complex.

What This Estimate Does Not Fully Cover

No simplified public calculator can safely cover every filing detail. Rebate, surcharge, exempt allowances, capital gains, house property adjustments, business income, and advanced deduction scenarios can all change the final return outcome. That is why this tool should be used as a structured estimate for comparison, not as a substitute for the full filing workflow.

Even so, the calculator is very useful because most regime confusion happens at the early planning stage. Users usually need a fast way to compare taxable income and likely total tax before they decide how much attention a deduction strategy deserves.
