Not sure what you mean by "it's a big deal". It's critically important to keep the LLC's finances completely separate from... but the effort to do so is not that high.

My limited understanding is that this varies from state to state, but at least in California, all that's really required is for you to have a separate business checking or savings account, and that receipts should be deposited there, and expenses should be paid from there.

Having a separate Federal Tax ID isn't even required in California, although it is definitely highly recommended. And at least in terms of trying to get a business banking account, many banks will require it.

And @jtbigwoo, you can have a single-person LLC that is "disregarded" as a separate tax entity from the IRS's point of view, which means any revenue to the LLC would show up in your personal income tax (on a Schedule C), known as "flow thru" accounting. That means that no, you don't necessarily have to pay separate dividends and stuff just because you are an LLC.
