I've come to love index funds ove the last 2 or so years, and I don't mind paying some taxes on profits.. however I know short term capital gain taxation may be something to avoid.

Short term rental taxation is often done incorrectly too- I'd recommend finding a REI specialized tax pro here on BP to ensure that everything is set up correctly and that it's being accounted for correctly.

(I need LLC to get Hard money loans, plus legal protection)I have been researching online, and was getting confused between double taxation, registering to do business in foreign state fees etc.Do I need to make an LLC in IN to buy property there?

However, its generally ill-advised apparently to hold real estate in an entity with a S Corp election because the "Corp-like" aspects make it less tax advantaged --- I don't remember the details but some sort of double taxation or something somehow sometimes comes into play. 

@Stephen Brown As Tom mentioned, it's crucial to ensure your CPA specializes in real estate taxation to ensure you're taking advantage of all possible tax strategies.

At the end of the day it's a form of taxation.

If that is the case then the basis will not be taxed on the conversion, but the earnings will still be subject to taxation when converted to Roth IRA, since the earnings have not been taxed. 

When you consider you have double taxation on a Corp, why would you do it if you do now have outside investor capital ( stock holders)?  

For example, a firm specializing in International taxation completes our client's International schedules, and we incorporate them.

What that is saying is that if your business has contractors, they are not viewed as employees that would need to be provided benefits under your 401k.There are two types of contributions to a Solo 401k:Employer profit sharing will come after the business pays its 1/2 of social security and medicare, but before your half as employee is paid.Employee contributions come after the full payroll taxes are paid.Both would not be subject to income taxation.
