Tax Deducted at Source (TDS) is the tax that is deducted by the employer or the deductor from the taxpayer and is deposited to the Income Tax Department on behalf of the employer. The TDS rates are set based on the age and income slab of different employees. TDS is the reduced amount when payments like salary, commission, interest, rent, or any other professional fees, etc., are made. Let’s understand a bit more about how to calculate TDS.
Importance of TDS Deduction

How are TDS Calculations Done?
Let us understand how to calculate TDS through an example. We shall consider that you are running a business in a property on rent, and you are supposed to pay the rent to the owner every month total rent costs Rs.50,000, which you are liable to pay the owner, then the TDS rate will be 5%. So, you shall be subtracting Rs.5000 from the gross rent, paying Rs.45,000 to the owner. The owner can add the net gross income of Rs.50,000 to the income.
The following table shows the tax rate for each tax slab:
- There is no tax levied for income up to Rs. 2.5 lakhs
- The tax Rate is 5% for income within the range of Rs. 2.5 lakhs to 5 lakhs
- For those who have income in the range of Rs. 5 lakhs to 7.5 lakhs, tax at 10% would be charged
- Similarly, the tax rates for the following ranges – Rs. 7.5 lakhs to 10 lakhs, Rs. 10 lakhs to 12.5 lakhs, Rs. 12.5 lakhs to 15 lakhs and Rs. 15 lakhs and above are 15%, 20%, 25% and 30%, respectively.
TDS Calculation Formula
In typical scenarios, the employers deduct their employees’ salaries at the average rate of their income tax. The general TDS calculation formula is
Average Income Tax = Income Tax Payable / Estimated Income Tax for that financial year

Let us say that you are working in a company that pays you Rs.1,00,000 as your salary. Your total salary will be Rs.12,00,000 per annum. Then the tax deduction will take place according to that particular year’s TDS rate for the income slab and use the TDS calculation on salary formula for estimating the deduction. This will give you the TDS amount. The TDS calculation formula is one of the very simplest and most convenient ways of calculating the TDS.
