I have a friend who is interested in learning how to lower his AGI for ACA subsidies. I’m looking for a good blog post that explains the various options, such as a solo 401k, tIRA, HSA, etc. I’m not comfortable leading him through it. I’d rather give him a link to the material and let him take it from there. I can’t find anything that quite fits the bill. Any recommendations? I’m looking for a single blog post that sums it all up.
