Except once it got to Nevada, it was split ten times and sent to ten different states. Where it was all sent to another country. It all came back together in the final country and deposited in a numbered account in some haven we haven’t heard of yet.
Practically untraceable.
Apparently, not to be a citizen for California for the purposes of taxation requires that you have been physically out of the state for 18 month. That you have not maintained a piece of property, a bank account or a social membership, such as in a church, also for 18 months.
A really wealthy guy could do as you suggest. But the average citizen simply can’t open multiple bank accounts easily. I had to show up in person with a birth certificate to open an account where I live. If I split my meager savings into 10 accounts, they’d all be local and all reachable by California if they so choose. As somebody once said, “Taxes are only for the little people.”
