A Boca Raton property owner is hauling a hefty tax bill into court, asking a Palm Beach County judge to toss out a $48.9 million 2025 assessment on a commercial parcel along Yamato Road. The lawsuit argues the county’s valuation is unlawful, inflated and ultimately forced the owner to pay far more in ad valorem taxes than a proper appraisal would have required.
According to Boca Post, MCM 301 Yamato LLC filed its complaint on April 16, 2026, in the Fifteenth Judicial Circuit (Case No. 502026CA004325XXXAMB), challenging the 2025 assessment for the property at 301 E. Yamato Road. The suit identifies the parcel as 06-43-47-05-00-000-5010 and names Palm Beach County Property Appraiser Dorothy Jacks, Tax Collector Anne M. Gannon and Florida Department of Revenue Executive Director Jim Zingale as defendants. The owner is represented by the law firm Lowndes, Drosdick, Doster, Kantor & Reed, P.A., through attorney S. Brendan Lynch.
The complaint cites a 2025 market value of $48,890,298 and an assessed value of $48,890,288 for the Yamato Road site and notes that the owner paid its 2025 tax bill, taking the standard 4 percent early-payment discount while explicitly reserving the right to challenge the valuation later. As Boca Post reports, the Palm Beach County Value Adjustment Board issued its final decision on March 12, 2026, and the complaint is now on file with the county clerk.

How the complaint describes the valuation
The lawsuit takes direct aim at the county’s appraisal work. It claims the methodology that produced the 2025 value was “unrealistic, unjust, excessive, and arbitrary,” and it alleges that the assessment swept in intangible property in a way the owner says runs afoul of the Florida Constitution…
