Tax Implications for Partners and Partnerships

Understanding how partnerships are taxed in the U.S. is fundamental for any business involving partners. Partnerships themselves generally do not pay federal income tax. Instead, they are treated as 'pass-through' entities. This means the partnership's profits, losses, deductions, and credits are 'passed through' directly to the individual partners, who then report these items on their personal income tax returns (Form 1040). The partnership files an informational return, Form 1065, U.S. Return

Partnerships are typically pass-through entities for tax purposes.
Partners report their share of income/loss on personal tax returns via Schedule K-1.
