The law specifies that all taxable personal property must be assessed as of a specific point in time, and that point is precisely at 12:01 a.m. January 1 (regardless of what transpires after that date). Even if closed shortly after the lien date, a business must still file a Business Property Statement and pay taxes for the coming fiscal year on any taxable property they owned on the lien date.
An LLC that does not want to accept its default federal tax classification, or that wishes to change its classification, uses Form 8832, Entity Classification Election (PDF), to elect how it will be classified for federal tax purposes. Generally, an election specifying an LLC’s classification cannot take effect more than 75 days prior to the date the election is filed, nor can it take effect later than 12 months after the date the election is filed. An LLC may be eligible for late election relief in certain circumstances. See About Form 8832, Entity Classification Election for more information.
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.
