What are TDS and TCS? (Simple Explanation)
What is TDS (Tax Deducted at Source)?
TDS is a tax deducted by the payer when making specified payments such as
Salary payments
Contractor and professional fees
Rent payments
Interest and commission
The deducted tax is deposited with the government and credited to the payee’s PAN.
What is TCS (Tax Collected at Source)?
TCS is collected by the seller from the buyer at the time of sale of specific goods or services, such as:
Scrap, coal, timber
Motor vehicles above the prescribed value
Overseas remittances
Certain e-commerce transactions
Both systems ensure advance tax collection and reduce tax evasion.
