IRS Updated Private Debt Collection Page Available on

20 August 2019

Before you are contacted by a private collection agency on behalf of IRS, you will receive two letters.

  1. 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.
  2. 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.


Some exciting news today – we have a fresh new Private Debt Collection page. The new site is launched. This is a big step forward and fulfills stakeholder requests to make the site cleaner and more user-friendly.
