The scam is an “official looking” letter from the IRS stating that you owe taxes related to the Affordable Care Act from the 2015 tax year. This notice is labeled "CP2000" and instructs you to send payment to the “IRS” care of an Austin, TX post office.
If the IRS sends you a legitimate letter, you will always be given a telephone number for you to call and resolve the issue. Also, authentic letters instruct you to make the payments payable to the US Department of the Treasury, NEVER to the IRS. A CP2000 letter issued by the IRS is when income or payment information does not match what you submitted on the tax form; not the Affordable Care Act.
This scam is also been transmitted through email. Remember, the IRS will NEVER contact you via email or by phone.
If you receive a letter like this and have questions, contact the IRS at 1-800-829-1040. If you know you don’t owe any taxes and want to file a scam report you can call the Treasury Inspector General for Tax Administration (TIGTA) at 1-800-366-4484 or online at the Federal Trade Commission (FTC) Complaint Assistant www.ftccomplaintassistant.gov.
