Tax Deducted at Source (TDS) is a tax collection method in India, where the person or entity responsible for making a payment to someone else is required to deduct a certain amount of tax at the time of making the payment, and then deposit the same with the government. TDS is applicable on various types of payments such as salaries, interest, rent, commission, and professional fees, among others.

TDS is governed by the Income Tax Act, 1961 and the rules and regulations issued by the Central Board of Direct Taxes (CBDT). One of the key responsibilities of the person deducting TDS is to file regular TDS returns with the Income Tax Department.
