for federal income tax purposes. An LLC with only one member is treated as an
entity disregarded as separate from its owner for income tax purposes (but as a
separate entity for purposes of employment tax and certain excise taxes). Also,
an LLC's federal tax classification can subsequently change under certain
default rules discussed later.
taxmap/pubs/p3402-001.htm#en_us_publink1000244331If an LLC does not choose to be classified under the above default
classifications, it can elect to be classified as an association taxable as a
corporation or as an S corporation. After an LLC has determined its federal tax
classification, it can later elect to change that classification. For details,
see
Subsequent Elections, later.
