Form 8890, also known as the Business Interest Expenses form, is for an individual, partnership, S corporation or corporation with business interest expenses. Besides, you'll need to file Form 8890 if you or the partnership have a disallowed business interest expense from the previous year or an excess business interest expense from the prior or current year.
A partnership passes its income to the partners, so the partnership must file the IRS 8890 form
. However, the partnerships must allocate excess taxable or business interest income to its owners.
