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.
