8990 - where does row 30 go next for 1040?

I am "married filing jointly" and receive a K-1 for a company I used to work at and still have equity in. That K-1 has info that requires me to complete the form 8990.

 

TT doesn't support Form 8990, so I complete it offline. However, I can't find any instructions from the IRS or other sources that indicates where Row 30 on the 8990 goes next.

 

Any idea where it goes next? Does it just live on the 8990 as some sort of informational item or does it flow through to the 1040 somehow?

It depends.  The following information about the business interest deduction and the limitations are show for you below. Any allowed amount will be used on Schedule A, if the amount is from your partnership K1. See the instructions linked below.

  • Line 30 is the amount of current year business interest expense deduction allowed after considering the section 163(j) limitation.
  • IRS Instructions Form 8990 - (page 9 for calculation of any disallowed expense and statement if necessary).

IRS FAQs for What are the limitations of 163j?

Q1. What is the section 163(j) limitation on the deduction for business interest expense? (updated January 10, 2023)

A1. Generally, taxpayers can deduct interest expense paid or accrued in the taxable year. However, if the section 163(j) limitation applies, the amount of deductible business interest expense in a taxable year cannot exceed the sum of:

  1. the taxpayer's business interest income for the taxable year;
  2. 30% of the taxpayer's adjusted taxable income (ATI) for the taxable year; and
  3. the taxpayer's floor plan financing interest expense for the taxable year.

Under the CARES Act, a different percentage (50%) of ATI may apply for taxable years beginning in 2019 and 2020. See the CARES Act, discussed later, and Revenue Procedure 2020-22 PDF, for ATI elections and special rules for partnership.

Thank you for the feedback, Diane. Are you referring to Line 16 of Schedule A? I didn't see any other line that looked applicable, but the Line 16 instructions list certain allowable deductions that don't include one for the business interest deduction from 8990 line 30. Perhaps I'm just not tracking still.

No, it should go on line 9 of your Schedule A. You can find this using the steps below and enter your investment interest expense.
