Concern “I’m not sure what to do about how to prepare for taxes.”  You take a portion out.  If you have a million dollars you should consider $300,000 or maybe even $400,000 doesn’t belong to you.  If you’re left with $500,000 or $600,000 be grateful for that….When you exchange your currency you are also taking out what you need to pay your taxes with of that amount.  Never never use money that doesn’t belong to you because how are you going to pay it back? [NOTE:  Consult your tax professionals to help you determine the appropriate amount of tax for your unique circumstances.]
