Submit your articles of organization with your personal name followed by "Limited Liability Company," or an abbreviation like LLC. State law generally requires that the registered name of your LLC specify the entity type. The state will conduct a search of other registered names and should approve the articles if the name is available and the other requirements are met. Alternatively, you could register under a different name and register a fictitious name (DBA) in your personal name.
Apply for an EIN in the name of the company. If you pay employees, the IRS requires the company have its own federal employer identification number. This will also be necessary to file your taxes if your LLC has more than one member.
Open a bank account in the name of the company. Make sure the primary name on the account is the registered name of the business. If you pay employees, the company's withholding tax must be paid from this account. Alcohol, tobacco, firearms and certain federal excise taxes must also be paid from this account.
Sign contracts that obligate the company in the name of the company. Make sure your signature in is your capacity as a member of the company and on behalf of the company.
