The Additional Medicare Tax was legislated as part of the Affordable Care Act, and has been in effect since 2013. Under this mandate, in addition to withholding Medicare tax at 1.45%, employers must withhold a 0.9% Additional Medicare Tax from wages paid to an employee once earnings reach $200,000 in a calendar year. Employers are required to begin withholding Additional Medicare Tax in the pay period in which employee wages reach $200,000 and continue to withhold it each pay period until the end of the calendar year. Additional Medicare Tax is only imposed on the employee. There is no employer share of Additional Medicare Tax. All wages that are subject to Medicare tax are subject to Additional Medicare Tax withholding if paid in excess of the $200,000 withholding threshold.
If you pay wages to
employees who are subject to Medicare tax (no matter whether you think you will ever pay any of them over $200,000), you must set up the payroll item Medicare Employee Addl Tax in QuickBooks if you haven't done so already.
Good news! Enhancements have been made with the latest QuickBooks release (QuickBooks 2015 and 2014 R6 or later) with an active payroll subscription automating the steps that add the Medicare Employee Addl Tax payroll item. Ensuring the payroll item is setup for each employee at the moment their paycheck is created.
Tip: To see which version of QuickBooks you have, press F2 on your keyboard. Your QuickBooks version and release (R) number appear at the top of the Product Information window.
