I am in the process of getting Bank of America to establish a lawful money account for me, specifying the terms of non-endorsement. Assuming I get this done (BofA is waffling, claiming they have 'never seen this' (surely BS), and that there is no 'signature sheet', but I expect to get past these issues. My question is this: when spending lawful money, no sales tax is allowed, but each vendor will want to argue this point. Has anyone asked the state Sales Tax Commission for an exemption number, which could be given to merchants so they are not responsible for the (unpaid) tax? Is there a better way to do this?
