 An imbalance of supply and demand continues to be at the core of what's driving prices. The IRS says some taxpayers are receiving a notice of non-payment even though they paid their 2023 federal income tax. Chief Tax Information Officer for Jackson Hewitt, Mark Stieber, says CP-14 notices are getting mailed to taxpayers right now. If you think the notice is incorrect, Stieber advises not sending a check right away and instead immediately contact the Internal Revenue Service or a tax pro about the issue.
