Let’s assume you talk to your attorney, and he advises you that you should create a reserve fund for taxes. Usually, it’s a good idea to listen to your attorney. If you don’t like his opinion, perhaps get a second opinion.
Of course, there’s also the Bozo method. The Miccosukee Tribe runs a successful casino near Miami, Florida. The tribe is exempt from taxes (it’s a sovereign nation). However, its members must pay taxes. They decided that they knew better than their attorney, and didn’t report distributions to its members or create a reserve fund in case their opinion was wrong. The Miccosukees filed a malpractice suit against their longtime attorney in a Florida court. The attorney had copies of his advice which pretty much (to this layman’s eyes) throws the malpractice case in the trash can.
Taxdood has more. Hint: The Miccosukee Tribe is the first nominee for the Bozo Tax Offender of the Year.
