Rather, there appears to be a closer-to-home explanation for at least some of the fees: Mr. Trump reduced his taxable income by treating a family member as a consultant, and then deducting the fee as a cost of doing business.
The “consultants” are not identified in the tax records. But evidence of this arrangement was gleaned by comparing the confidential tax records to the financial disclosures Ivanka Trump filed when she joined the White House staff in 2017. Ms. Trump reported receiving payments from a consulting company she co-owned, totaling $747,622, that exactly matched consulting fees claimed as tax deductions by the Trump Organization for hotel projects in Vancouver and Hawaii.
