  3. The lowest of the following amount is calculated as tax exemption under HRA:
    1. Actual rent paid less than 10 % of the basic monthly salary
    2. Employer provides the HRA
    3. If the taxpayer is living in a metro city, 50% of the basic salary

  2. Tax rate is nil for net income up to Rs.5 lakh for taxpayers over 80 years of age.

Calculate the Taxes Imposed

Tax is calculated on your taxable income which is zero for the first Rs2.50 lakh and 5.00% for the next Rs.2.50 lakh. While the tax rates are 20% and 30% for the next Rs.5 lakh and above Rs.10 lakh, respectively.

Consolidate your Net Tax

If an individual is earning below a specified limit, then the government provides tax incentive in the form of tax rebate. Health and education cess of 4.00% can be added to your tax amount if total taxable income is above Rs.5 lakh. The surcharge amount added is 10% and 20% if the income falls between the range of Rs.50 lakh to Rs.1 crore and Rs.1 crore to Rs.2 crore, respectively.

Example:

A person X earns a total gross salary of Rs.15 lakh and the net salary comes to Rs.12.50 lakh after removing all the exemptions, such as standard deductions and HRA (House Rent Allowance).

  1. The total of the basic wage, the HRA, the special allowance, the transport allowance, and any other benefits is income from salary. Your income may include tax-free benefits such leave travel expenses and phone bill reimbursement.
  2. Renters who receive HRA are eligible to make an HRA exemption claim. By using our HRA Calculator, you can determine the HRA's exempt portion.

In addition to these exemptions, the 2018 budget also included a standard deduction of Rs. 40,000. This was raised to Rs 50,000 in the budget for 2019 and to Rs 50,000 more in the budget for 2023. During the Union Budget 2024, the maximum deduction one can claim if opted for New Regime is Rs.75,000.

A standard deduction of Rs 50,000 is also available in the event of a new administration. You won't be able to make use of these exemptions if you choose the new tax system.

Generation of any kind of income will be taxable, provided you (the tax-assessee) categorises each income under the aforementioned sources.

Income from Salary

The Income Tax Department of India lists 5 sources of income under which each person can designate their income. One such source is your income from salary. You can make efficient use of your income tax calculator to evaluate the entire value.

Your income from salary can be calculated by using the TDS certificate, that is a part of Form 16. Note that, your employer is supposed to provide you with a Form 16. This can be achieved in the following ways:

  1. Gather all your salary slips and the essential Form 16 of the ongoing financial year. Add up all your stipends and allowances (this includes your basic salary, TA, DA, HRA, DA on TA, reimbursements) that is listed in your payslip and the Form 16 (Part B). Once this is done, add your bonus.
  2. The total value that you get after computing all this will be termed as your gross income.
  3. Make the following deductions from your gross income - HRA exemption and allowance for transportation (the exemption limit is Rs.19200 p.a.)
  4. The total result will act as your net income.

Income from Capital Gains

The nature and number of transactions usually determine the computation of income from capital gains. It can be attained in the following manner:

  1. Calculate your long-term capital gains from your total sales of assets.
  2. Calculate your short-term capital gains from the total sales of capital assets.
  3. Deductions are to be claimed after this.

Income from House Property

Income from house property is that which the assessee receives every month in the form of rental payment. In case, the tax-assessee has the possession of only one house, and that too is self-occupied then also he has to compute his income through property.

Calculate the GAV (Gross Annual Value) of your rented house property in the following ways:

  1. Take into consideration the Fair Market Value (FMV) and the valuation estimated by municipal authorities (Municipal Valuation). Take the amount that is higher in value and this shall be your expected rent.
  2. Compare the rent you receive (the Actual Rent) with the aforementioned expected rent and you have your Gross Annual Value for the house.
  3. You can compute the Net Annual Value (NAV) by deducting the already paid municipal taxes during the GAV year. Deduct the same from the NAV to comprehend the loss or income from your housing property. 30% of NAV - Interest paid annually on the loan amount (if taken to buy the said house

6. Steps for Income Tax Calculation
