It’s worth mentioning that the income limit for contributing to a Roth IRA does NOT apply to Roth 401k accounts, which is likely another “incentive to keep working for the man”. Sole proprietorships/startups and their employees are punished severely for taking people out of the “corporate workforce”, and this is one such way.
My favorite way is paying Uncle Sam almost 40% in taxes on income made as a sole proprietor. Bad cog! Bad!
