Worried about filing deadlines? Get one step ahead by estimating your taxes with the help of an Income tax calculator. It works like your personal financial assistance, helping you compare the old and new income tax regimes. You can calculate accurate numbers just by adding a few details, gaining clear financial control.

The income tax calculator serves as an online tool that calculates the income tax you need to pay for the financial year. It not only simplifies your financial planning but also helps you make informed decisions throughout the financial year.

The income tax calculator is simple and easy to use. Follow the steps given to use an income tax calculator effortlessly:

  • Select the financial year as FY 2025-26 to get calculations based on the latest tax rules.
  • Enter your age. Different age groups have different tax exemption limits.
  • Fill in your total income from all sources, including salary, rent, interest, and other earnings.
  • Add the amount of tax deductions you can claim. These can be investments under section 80C or medical insurance under section 80D.
  • Choose whether you want to use the old tax regime, which allows deductions, or the new tax regime which has fewer deductions but lower tax rates.
  • Click on the calculate button. The tool will give you the tax payable, including applicable cess and surcharge.

To calculate your income tax seamlessly, follow the given steps:

Step 1: Determine your gross total income by adding your salary, business, house property, capital gains, and other earnings.
Step 2: Lower your taxable income by reducing the eligible deduction. These may include HRA, home loan interests, section 80C, and section 80D.
Step 3: Next, select between the old and new income tax regimes and choose the one with the lower tax liability.
Step 4: Now, proceed to calculating your tax based on slab rates according to your choice of regime.
Step 5: Lastly, move to compute the basic tax and include the surcharge, followed by 4% cess to receive your final tax to be paid.

Note that the new tax regime has lower slab rates but does not allow most deductions. Whereas the old tax regime allows deductions but has higher slab rates.

While the old income tax regime allows taxpayers to claim different deductions or exemptions, the newer regime offers lower tax rates, removing exemptions to simplify tax calculation. Some of the deductions included in the older income tax regime were Medical insurance and HRA.

The old income tax regime is best suited for taxpayers who invest in tax-saving tools. This is most beneficial when the claims involve housing loan interest, multiple deductions, or HRA.

A taxpayer who has a simple salary with fewer deductions can benefit from the new income tax regime. Individuals who prefer minimal paperwork or documentation can also benefit from the new regime.

A salaried employee can switch between the old and new income tax regimes each financial year. This is not possible for business owners due to limited opportunities.

Some deductions that are included under the old income tax regime are as follows:

  • Section 80C investments,
  • Section 80D health insurance
  • HRA
  • Home loan interest under section 24
  • Education loan interest
  • Donations under Section 80G

The total income tax has an addition of 4% health and education cess, including surcharge payable. This increases the final tax liability.

The surcharge is applied based on the income slab, which ranges between 10% and 37%. This percentage is for high-earning individuals, applied before adding cess.

The best time to use the income tax calculator is at the start of your financial year, before filing returns. This will help you in proper financial planning, allow mid-year adjustments, and ensure accurate tax calculations.
