Calculating income tax on salary involves a series of steps — from arriving at your gross salary to applying the correct slab rates. Follow this step-by-step breakdown to understand exactly how your tax is computed.
Step 1: Determine Gross Salary
Your gross salary is the starting point of any tax calculation. It includes your basic pay, dearness allowance (DA), house rent allowance (HRA), leave travel allowance (LTA), bonuses, and any other benefits paid by your employer. Note that employer contributions to the Provident Fund (PF) are excluded from your gross salary for tax purposes. Getting this figure right sets the foundation for an accurate tax calculation.
Step 2: Determine Gross Total Income
Once you have your gross salary, add any income earned from other sources — such as rental income from property, interest earned on savings accounts or fixed deposits, or any freelance or side income. The sum of your salary income and these additional earnings gives you your Gross Total Income, which is the base figure before any exemptions or deductions are applied.
Step 3: Apply the Standard Deduction and Exemptions
Salaried individuals are eligible for a standard deduction of Rs. 50,000 from their gross salary — no bills or proofs required. Over and above this, you can claim exemptions on allowances such as HRA (based on rent paid, salary, and city of residence) and LTA (for travel within India). These exemptions directly reduce the income that goes into your tax calculation, lowering your overall liability.
Step 4: Apply Deductions
After exemptions, apply eligible deductions to further reduce your taxable income. Section 80C allows deductions of up to Rs. 1.5 lakh on investments such as ELSS mutual funds, PPF, NSC, and tax-saving FDs. Section 80D covers health insurance premiums. Other deductions include Section 80E (education loan interest) and Section 24(b) (home loan interest), among others.
Pro Tip: ELSS mutual funds have the shortest lock-in period among all Section 80C options — just 3 years — while offering market-linked returns.
Step 5: Determine Taxable Income
Once all applicable exemptions and deductions have been applied to your Gross Total Income, the resulting figure is your Taxable Income. This is the amount on which your income tax will actually be calculated. A lower taxable income means a lower tax outgo — which is why making full use of available deductions, especially under Section 80C through ELSS investments, is so important.
Step 6: Apply Income Tax Rate
With your taxable income determined, apply the applicable slab rates. You can choose between the old tax regime (higher rates but allows deductions and exemptions) or the new tax regime (lower rates but limited deductions). Match your taxable income against the respective slabs for the financial year to arrive at your basic tax liability before any rebates or cess.
Step 7: Apply Rebate, Cess, and Surcharge if Applicable
After calculating your basic tax, check for applicable rebates. Under Section 87A, individuals with a net taxable income up to Rs. 5 lakh (old regime) are eligible for a rebate of up to Rs. 12,500, effectively making their tax liability nil. A health and education cess of 4% is applied on the tax payable. High-income earners may also attract a surcharge. These final adjustments give you your actual tax liability for the year.
