Involving fake tax notices related to the ACA. Beware of any email you may receive from the Internal Revenue Service (IRS): It’s a scam. There’s been an uptick of people receiving fake notices regarding tax bills tied to the Affordable Care Act (ACA), the Wall Street Journal reports. The notice asks taxpayers without proper coverage to pay a penalty for ACA coverage they elected in 2014. The thing is the IRS doesn’t contact taxpayers by email, according to the Journal, so tax notices in your inbox are a sure sign it’s fake.
