After you've completed the steps described above, your LLC is official. But before you open your doors for business, you need to obtain the licenses and permits that all new businesses must have to operate. These may include a business license (sometimes also referred to as a "tax registration certificate"), a federal employer identification number, a sellers' permit, or a zoning permit. For more on business licenses and permits, see the Licenses & Permits for Your Business area of Nolo's website.
Another important component when you are determining how to form an LLC is the creation of an LLC operating agreement. While operating agreements are not required under state law when forming an LLC and do not have to be filed with the state, they are very important documents to create because they help you and any other members of the LLC organize your business, plan for the future, and put all pertinent facts in writing.
Get an Employer Identification Number from the IRS. If your LLC has more than one member, you will need this number so your LLC can pay federal and state taxes properly, hire employees, and open a company bank account. You can apply for this number: (1) online; (2) by contacting the IRS at (800) 829-4933; or (3) by completing and mailing in Form SS-4 to the address listed on the form.
Articles of organization are short, simple documents. In fact, you can usually prepare your own in just a few minutes by filling in the blanks and checking the boxes on a form provided by your state's filing office. Typically, you must provide only your LLC's name, its address, and sometimes the names of all of the owners -- called members. Generally, all of the LLC owners may prepare and sign the articles, or they can appoint just one person to do so.
In a few states, you must take an additional step to make your company official: You must publish a simple notice in a local newspaper, stating that you intend to form an LLC. You are required to publish the notice several times over a period of weeks and then submit an "affidavit of publication" to the LLC filing office. Your local newspaper should be able to help you with this filing.
If you received a Notice to File a Business Property Statement from the Assessor and your business is no longer in operation, you are still required to file the Business Property Statement. You should also include a note on the Business Property Statement indicating that the business has closed, so the Assessor does not continue to assess the property.
