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.
On the other hand, if you are not responsible for its tax, then you should declare the equipment in Part III of the Business Property Statement (Equipment belonging to others). Where equipment is declared in Part III of the Business Property Statement, the Assessor will also send a Notice to File to the person reported as the equipment's actual owner.
