Following the plan, seems like one of the first things that I need to do is to take care of a bank account. I see different options:

1. Use existing (interest bearing) account and do Notice and Demand against it. As a consequence I will be gladly paying taxes on all accrued interests.
2. Somehow make the bank to convert existing one from Interest bearing to non-bearing account. Does anyone has experience or at least procedural understanding on how to do this?
3. Open new account, without signing W-??. When asked why I am not signing W-??, what would be my explanation to the clerk?

What would be the best option from your experience? If there are legal implications associated with either choice, I would highly appreciate simplified explanation (plain English)(if possible), so that people (me including) who just starting will have easier comprehension.
