Tax Deducted at Source or TDS is a source of collecting tax by the Government of India at the time when a transaction took place.
The tax is required to be deducted at the time money is credited to the payee’s account or at the time of payment, whichever is earlier.
In case of payment of salary or life insurance policy, tax is deducted at the time of payment. The deductor then deposits this TDS amount to the Income Tax Department. Through TDS, some portion of your tax is automatically paid to the Income-tax department.
