Two former executives from Kraus Anderson, the company that built former UnitedHealth Group CEO Bill McGuire’s Gold Medal Park in Minneapolis, have pled guilty in federal court to avoiding taxes on free landscaping at their homes. The company that provided the free work, Windsor Landscaping, also did the landscaping work at Gold Medal Park — on McGuire’s recommendation. A postal inspector has testified that McGuire also received discounted home landscaping as a quid pro quo for steering the work at Gold Medal Park to Windsor (a charge McGuire’s attorney denied). Windsor’s owner pled guilty in March to hiding the free work so it wouldn’t be taxed. The two Kraus Anderson execs face possible prison terms, the Star Tribune reports.
