Who is the Automated Collection Service (ACS) of the Internal Revenue Service (IRS)?

The Automated Collection System (ACS) is a division within the IRS that focuses on “balance due” accounts and “non-filer cases.” In other words, those taxpayers that owe the IRS money and/or have not filed tax return(s). ACS handles incoming and outgoing phone calls, generates wage and bank levies and sends out collection notices. Additionally, ACS monitors and tracks taxpayers’ accounts. Based on our experience, ACS can be very aggressive with their collection efforts.
