Income Tax Calculator

An income tax calculator is an online tool designed to estimate your tax liability based on the provisions of the Income Tax Act, 1961. It uses the applicable slab rates for the selected tax regime and assessment year. The calculator allows you to enter details such as annual income, deductions under sections such as 80C (up to ₹1.5 lakh), 80D, housing loan interest, and other eligible exemptions under the Income Tax Act, 1961, which are generally available under the old tax regime. It then estimates your tax liability under both the old tax regime and the new tax regime, enabling a structured comparison. In this way, it can also aid users who are unfamiliar with taxation norms or the technical aspects of income tax filing. Many tools also function as an income tax return estimator by showing:

• Gross total income
• Taxable income after deductions
• Rebate eligibility
• Final tax liability

An income tax calculator helps you estimate your tax payable by considering your income, deductions, exemptions, and chosen tax regime. It subtracts eligible deductions to determine your taxable income and applies the relevant tax slab to show your total tax liability.

Here are some tips for calculating income tax using this income tax planner:

• Choose the tax regime that offers a lower tax liability.
• Utilise deductions under Section 80C, 80D, and 80G of the Income Tax Act, 1961, for tax savings (for those opting for old regime)
• Ensure accuracy by entering all sources of income.

While the calculator does the work instantly, understanding the process helps you stay informed. Steps to calculate income tax:

1. Calculate gross income: Add salary, capital gains, rent, and other earnings.
2. Apply exemptions: Deduct standard deduction and eligible exemptions. Under the new regime, only limited deductions apply (Sections 24b, 80CCD(2), and 80CCH).
3. Find taxable income: Subtract exemptions from gross income.
4. Apply tax slabs: Identify the applicable slab.
5. Compute tax liability: Calculate total tax payable as per the chosen regime.

– Annual income including salary (minus HRA) and income from other sources: Rs. 10,00,000

• Deductions: Rs. 1,50,000 under Section 80C
• Standard deduction: Rs. 50,000
• Tax computation: Based on income tax slabs, the tax payable is Rs. 75,400 (with cess).

In this case, the new tax regime might be beneficial for the individual. However, the computation can change if all the applicable deductions under the old tax regime are fully utilised.

• Annual income: 10,00,000
• Standard deduction: 75,000
• Taxable income: 9,25,000
• Tax computation: Based on the applicable income tax slabs, the total tax payable is Rs. 33,800 (inclusive of cess). However, as per the taxable income is below Rs. 12,00,000 the individual may be eligible for a rebate under Section 87A, reducing the tax liability to nil.

Calculating income tax for a salaried employee is easy with an online income tax calculator. By entering your salary, deductions, and exemptions (if any), you can quickly estimate your tax liability. Some tools also act as an income tax return calculator, helping you plan your finances and know the taxes payable before filing your ITR.

As a first step, the calculator computes the total taxable income. Broadly, this involves adjusting gross income for eligible deductions and exemptions, where applicable. For instance:

Taxable income = Gross salary + Other income – Standard deduction – Eligible deductions and exemptions (such as those under sections 80C, 80D, or House Rent Allowance of the Income Tax Act, 1961, primarily under the old tax regime)

Once the taxable income is determined, the applicable tax slabs for the chosen regime are applied to arrive at the tax amount.
