LP, Limited partnership: a partnership where at least one partner (the general partner, which may itself be an entity or an individual) has unlimited liability for the LP's debts and one or more partners (the limited partners) have limited liability (which means that they are not responsible for the LP's debts beyond the amount they agreed to invest). Limited partners generally do not participate in the management of the entity or its business.
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.

You may be able to operate under a name other than your formal LLC name by applying for and using a dba.
