Is a separate TAN required to be obtained for the purpose of tax collection at source?

In case a TAN has already been allotted for the purpose of tax deduction at source (TDS), then no separate application needs to be made for obtaining separate TAN for the purpose of tax collection at source (TCS). The same number can be quoted in all returns, challans and certificates for TCS. However, if no TAN has been allotted, a duly filled in Form 49B, along with the application fees is to be submitted at any TIN-FC.
