A 2015 Tax Court case, Leland, Jr. v. Commissioner,1 involved an Internal Revenue Service objection to the deductibility of losses alleged by IRS to be passive activity losses which, if upheld, would have denied deductibility. Litigated cases involving landlord and tenant where the issue is passive activity losses are relatively rare.
