You can always use a company like LegalZoom that will help you with all the paperwork etc, (I think it’ll cost about $200-300) or go through your Accountant. I hit quite a few obstacles doing this on my own but hopefully with these steps, it will be easier for you.
1. Find a company name that is not already being used. If you’re filing in Nevada, make sure your company name has ‘LLC’ at the end of it, i.e. Tadlock Enterprises, LLC. If it doesn’t, you’ll get rejected and that’s always fun. http://nvsos.gov/sosentitysearch/
2. Download the application form for Articles of Organization. I would recommend mailing the form to the Resident Agent (i.e. MailLink), getting it signed and have them mail back (Nevada Secretary of State rejected my faxed copy). http://secretaryofstate.biz/business/forms/llc.asp

3. Find a Resident Agent and have the Resident Agent sign the 1583 form (available on the Mail Link site) I am using Mail Link LLC as my Resident Agent and rent a small mail box for $100/year. Their website is www.maillinkplus.com. You can Google Nevada Resident Agent to find others.
4. File the Articles of Organization and send that and the Resident Acceptance Form (1583) to Nevada Secretary of State Office.
5. When you receive the certificate of your corporation from the Nevada Secretary of State office, go to IRS site to get your Employer Federal ID (EIN number). http://www.irs.gov/businesses/small/article/0,,id=102767,00.html
6. Once you have your EIN (and everything else is setup i.e. Articles, Sec of State approval etc), you can setup your business bank account (it’s recommended to setup the account in the same state you’ve setup your LLC in).
NOTE: I obtained my EIN first and then did everything else because my recruiting company needed that right away but if it’s not required, you can do it in the above order.
Hope this helps!
