What is Line 13 AE on my K-1?

Box 13, Code AE on Schedule K-1 is used to report expenses that do not fall into any other category of deductions. For example, Management Fees are a type of expense charged to the SPV that appear in Box 13 AE and are classified as other "miscellaneous deductions that are subject to 2% AGI limit." However, as a result of the Tax Cuts and Jobs Act (TCJA) in 2018, investment-related expenses previously deductible will not be available as a deduction on your tax return.
