Thanks Amy; after posting my message I did some more digging and found the same information as you have posted here. While I now understand the reason, MFJ as the guiding criteria for the Additional Medicare Tax does not logically make sense to me. A self employed person MFJ filing a Sch C is already paying self employment taxes of 12.4% for social security and 2.9% for medicare on their self employed earnings and to then pay an additional .09% of additional medical taxes because the spouses earnings exceed the $250k threshold seems illogical to me. 🤔 Thanks again Amy.
