Do you have to open a business bank account for a business or can a person account do?

You don't have to have a seperate account for tax purposes. If you record the income and expenses for the LLC and keep the books seperate, the government doesn't care where you keep the money. Stick it under the matress! :) However, if your company receives payment in checks written to the company, the bank probably won't let you put them into an individual account. (Mine did for a while, none should legally.) Also, if you ever want to establish credit for your company, you need a seperate account. Reconciling your bank statement to your expenses (and therefore balancing your corporate books) is also going to be a REAL hle and prone to errors... In short, you should open a seperate account and will probably have to for practical reasons, but legally, you don't have to. Ask your accountant, they'll tell you point blank to keep seperate accounts.
