Business-entity tax guides for sole proprietors, S corporations, partnerships, and C corporations
An LLC label does not by itself determine the federal tax return. The filing path depends on the entity's ownership, tax classification, elections, activity, payroll, transactions, and state obligations.
These guides help owners identify which return or election may be involved and which records should be organized. They do not assume that one entity type is best for every business; formation, legal, payroll, and tax decisions should be evaluated together with the appropriate professionals.
PRIORITIZED READING PATH
Choose the guide that matches the business and filing question
Start with the entity comparison if the filing structure is unclear, or go directly to the return, election, or reporting guide that applies.
