Beginning in the spring of 2017, the Internal Revenue Service will use some private debt collectors to act on its behalf, to collect outstanding taxes.
Remember to scrutinize whether any IRS debt collection effort is from a legitimate source. There are a multitude of fraudulent telephone calls, and email claims. Never pay an IRS debt claim (or other claim) utilizing a prepaid debit card. If someone insists you do so, it is a clear sign of a fraudulent claim.
IRS payments should always be made payable to the United States Treasury and sent directly to the IRS, not to the private collection agency.
