What Is A K1 Tax Form? A K-1 tax form is required to report income, deductions, and credits of a partnership, S-corporation or trust. It includes the amounts of earnings, losses and dividends that are transferred to individual partners, shareholders or beneficiaries. They have to declare the information in their personal income taxes because the business entity does not pay taxes on this income.
