What Makes Partnership and LLC Taxes Different?

Partnerships and most LLCs are taxed as pass-through entities, which means the business itself does not pay federal income tax. Instead, income, deductions, credits, and losses are reported on a partnership tax return (Form 1065) and passed through to partners or members using Schedule K-1.

Because each partner’s personal tax return depends on accurate allocation, filing partnership taxes online requires precise reporting of ownership percentages, income distribution, and expenses. Errors in Form 1065 or Schedule K-1 can directly impact individual tax filings.

Understanding these requirements is critical when you efile partnership tax returns online
