I apologize if this is not relevant to this group. I am a software consultant. I work through my LLC. My LLC has a Solo 401K plan in which I contribute $19500 + 25% profit as per the law. Unfortunately, my wife legally cannot contribute to this plan because she doesn't work for this company. But we want to maximize her retirement contribution. So, we are considering to buy a business (thinking to buy a Laundromat at this moment) for her so that she can contribute to the retirement plan. Considering this situation, which type of company should we open to run the business - S-Corp, C-Corp, LLC or partnership ? I understand I need to talk with a CPA, but I want to enhance my knowledge even before talking with a professional.
One more thing: We have significant medical expenses. We bought health insurance from the marketplace. We have a HSA account where we contribute the maximum. But that is not enough to cover our medical expenses. I have read about HRA. I also learned that in some cases HSA and HRA are compatible. Which business type will be good to open a HRA ? Is there any example for this ?
Please advise considering both the situations.
