Summary: Tax Collected at Source (TCS) applies to specific transactions under Section 206C of the Income Tax Act, where the seller collects tax at the time of receiving payment. Unlike TDS, which is deducted by the payer, TCS is collected by the seller. Transactions subject to TCS include alcoholic liquor, tendu leaves, timber, scrap, toll plaza fees, and sale of motor vehicles, among others. The collector is required to file Form 27EQ quarterly, detailing the collectee whose TCS has been gathered. The due date for filing Form 27EQ is the 15th of the month following each quarter’s end, except for the last quarter (January to March), for which the due date is May 15th. Conversely, TCS challan payments are due monthly, by the 7th of the following month in which the TCS was collected. A TCS certificate, Form 27D, is issued by the collector to the collectee quarterly. Failure to collect TCS on time incurs interest at 1% per month or part thereof from the date it was collectible until actual collection. If TCS is collected but not deposited on time, interest is levied at 1.5% per month or part thereof from the date of collection until payment. Notably, such interest on late collection or payment is disallowed as an expense under the Income Tax Act.
