A citizen's first income tax payment is a milestone in his or her life. For a first-timer, however, the process can seem overwhelming and tedious, and even some of the terms can be difficult to understand. However, there is no need to worry. For beginners, here is a compilation of basic income tax information that can help you understand the tax implications of your income.

Calculating your income tax liability is easy. Just follow the simple formula:

Sum of all Your Earnings = Total Gross Income – Deductions = Taxable Income

(First, add up your earnings to arrive at your total gross income and then subtract applicable deductions the answer is your taxable income).

Here’s a brief guide to help you calculate your taxable income:

  1. Salary Income: Collect all your salary slips as well as Form 16. Add all allowances (HRA, TA, DA, medical, etc.) and reimbursements, including any bonuses to arrive at your gross salary. Deduct the applicable exemption amounts of HRA, LTA, and medical expenses, if any. Keep in mind that you are allowed standard deductions of ₹50,000 on your annual salary.
  2. House Income/ House Rent Allowance (HRA): Firstly, calculate the net income you receive from your property, mainly the rental income. Profit from a self-occupied house will also need to be computed (although, it will generally be nil or negative value).
  3. Income from Capital Gains: Income from Capital gains is any income you get from the sale of stocks, bonds, or property. Your capital gains may either be short-term or long-term. So, the third step is to calculate both your short-term capital gains and long-term capital gains. Also claim any deductions under Sections 54, 54G, 54ec, if they apply. What remains after this is your capital gains income.
  4. Business Income: To calculate the taxable income from your business, take the net profit made in the financial year as the base value. Add all the deductions allowed as per the IT act and subtract all the expenditures as per Income Tax Laws.
  5. Income from Other Sources: Income from interest earned on fixed deposits or saving accounts, dividends from mutual fund schemes, any income from gifts, family pension, lottery, or horse races are classified under this category. Add them up and subtract any deductions to arrive at your net income.
  6. Gross Total Income: Add up all your earnings from the sources above. That equals your total gross income. Set off losses, if any, when you calculate income tax.
  7. Deductions Under Chapter VI A: These deductions include investments made under Section 80C to 80U of the Income Tax Act, ELSS, PPF, ULIPs, NPS, VPF, NSC, tuition fees, life insurance policies, and mediclaim/heath insurance policies.
  8. Calculate Your Net Taxable Income: To calculate net taxable income, you finally need to subtract Step 7 from Step 6. Now apply the tax rates under which your income falls. The result is the final income tax amount you’ll be required to pay.
  9. Calculate Your Tax Payable: Once you have effectively reduced your tax liability in the prudent way described above, you may proceed with the calculation of your tax liability, as per the latest income tax slabs.
