A Schedule K1 is a form used to report “pass-through” earnings to theIRS for tax purposes. The form details the earnings of individuals with interest or ownership in certain types of businesses and makes the individual, rather than the business entity, responsible for paying taxes due on earnings. The specific earnings amounts paid to each individual are detailed on the K1and other forms so that the IRS can apply appropriate taxes.

Who Receives a Schedule K-1?

A separate Schedule K-1 is prepared and filed for each partner or other people who receive ownership income (i.e., not wages or bonuses) from a business. It is completed by an accountant and filed with Form 1120S (for S Corporations) or Form 1065 (for Partnerships).

Partners and shareholders will use a Schedule K-1 to report important earnings information on their tax returns (Form 1040). These forms are used to calculate the taxes owed.

What is Included in a Schedule K-1?

A Schedule K-1 details the income, losses, and dividends that are allocated to a business partner. This includes:

  • Ordinary business, rental, and real estate income.
  • Guaranteed payments and interest income.
  • Dividends and dividend equivalents.
  • Short- and long-term capital gains and losses.
  • Other items including royalties, collectibles, self-employment earnings, other income, and deductions.

Partnership Agreements and the Schedule K-1

Partnership agreements are used by certain types of businesses to state the ownership, interests, drawings, and other factors of how business owners will run the business and receive earnings. The amounts and information reported on Schedule K-1 will be influenced by the original partnership agreement and any subsequent changes. For example, if there are two partners with equal ownership and the business distributed $200,000 between them, each partner would detail the $100,000earned on Schedule K-1.
