In part one of this two-part Payroll Brass Tax podcast series, Mike Mahoney (shareholder, Morristown/New York), who is the chair of the Employment Tax Group, is joined by Stephen Kenney (associate, Dallas) to demystify unemployment tax rate notices—the one piece of mail that can swing your payroll costs by thousands or even millions. The speakers unpack how rates are calculated, what to check the moment a notice arrives, as well as when and how to appeal.
