What if I reached the additional Medicare tax threshold with a previous employer?
You employer must begin withholding the Additional Medicare Tax (0.9%) from your wages once it has paid you wages in excess of $200,000. If you earned over $200,000 from a previous employer in the same year, you are still responsible for paying the additional tax, but your current employer may not be willing or able to handle these extra withholdings for you.
Contact a tax advisor for more information and instructions on handling the additional withholding. For example, you have the option to make estimated payments if you expect to have any liability for the additional tax, or to request that your current employer withhold additional income tax on Form W-4, which can then be applied to all taxes on your Form 1040.
Thank you for the feedback!
