Private Collection Agencies
The law requires the IRS to use private agencies to collect certain outstanding, inactive tax debts.
If your tax debt has been transferred to a private collection agency, you will be contacted by one of these four private collection agencies on the government's behalf:
How it works
Before you are contacted by a private collection agency, you will receive two letters.
- The IRS will first send Notice CP40 and Publication 4518 . These let you know that your overdue tax account was assigned to a private collection agency.
- The private collection agency then sends their initial contact letter. It has information on how to resolve your overdue taxes.
Both letters contain a Taxpayer Authentication Number. It’s used to confirm your identity. It’s also for you to verify that the caller is legitimate. Keep this number in a safe place.
