Thanks for the quick reply TGB,

Crazy that they have to pay a huge penalty for two months of marriage

Couple was married in October, 2023

No kids or other people

She made $135k in TY2023. 

He made $36k net (self-employed) in TY2022 and will probably make the same for TY2023.

All is good until I get to Part V

Can't seem to get the Alternative Family size for each (has to be 1 or 2) and start month (October) & end month (December) to jive
