Ten Trump-related properties are valued at nearly $80 million, with Mar-a-Lago alone appraised at $26.6 million, according to estimates released Monday.

Ownership entities related to President Donald Trump could pay as much as $1.48 million in 2019 taxes on Palm Beach County properties, including Mar-a-Lago, the president’s winter White House. That’s according to preliminary estimates released Monday by county Property Appraiser Dorothy Jacks.

In all, the latest so-called "total market value" of 10 Trump-related properties in the county adds up to $79.44 million, according to an analysis of the property appraiser’s preliminary figures by the Palm Beach Daily News. Of that total, slightly less — $79.36 million — is taxable, the analysis shows.

Trump-related properties in Palm Beach include three houses next to Mar-a-Lago, the private club that serves as the president’s residence on his visits to Palm Beach. Trump-linked taxable properties elsewhere in the county include the clubhouse at the Trump International Golf Club near West Palm Beach and all of the Trump National Golf Club in Jupiter.

In Palm Beach alone, the six Trump-related properties have a preliminary total market value of $53.84 million, according to records.

Of that total, Mar-a-Lago — with its 17.5 ocean-to-lake acres — has a total market value of $26.6 million, the same as its taxable value. The club at 1100 S. Ocean Blvd. would be billed $521,840 in taxes and assessments this year, an increase over last year’s bill of $488,943, the preliminary figures show.

The new data shows the club's taxable value is up about 4.7 percent from last year's final $25.4 million valuation. That's less than the increase townwide of taxable values, which climbed an average of 5.82 percent, according to the preliminary estimates.

Trump’s estimated tax bills are generally higher than last year’s, reflecting an overall increase in his properties’ values.

That upward trend has been noted countywide, Jacks said in a prepared statement.

"Palm Beach County’s market value continues to experience a steady increase year over year. Construction in apartment complexes, hotels, and warehousing is helping to create value in many areas," Jacks wrote.

Jacks’ office on Monday mailed owners notices of estimated values for all county property and the taxes they likely will generate. The new values were assigned to each property, including the Trump holdings, on Jan. 1.

The notices reflect tax rates and fees set by municipalities, the county, the public school district and other taxing authorities — and the preliminary estimates could change after those entities finalize their budgets in September. The estimates also could change for property owners who successfully contest their valuations.

State law requires tax bills be mailed by Nov. 1.

Lowest tax rate in the county

Palm Beach officials, like other authorities, typically set their tentative tax rate higher than the one they expect to finalize by the end of September, so there is some wiggle room should changes be needed. The proposed overall tax rate in Palm Beach is the lowest in the county at $16.84 per $1,000 of a property’s taxable value, according to Jack’s office.

Last year at this time, the preliminary tax estimate for Trump-related properties in the county totaled $1.36 million, and that figure held steady through the November mailing.

But an exact year-over-year comparison of Trump properties isn’t possible because the 2018 tax tallies included a pro-rated amount for a house at 1125 S. Ocean Blvd. near Mar-a-Lago.

An entity associated with the president bought that oceanfront house and a vacant parcel next door for a recorded $18.25 million in May 2018 from one of the president’s sisters, retired federal judge Maryanne Barry. Under standard real estate sales protocol, about $130,180 in pro-rated taxes would have represented the share of taxes owed after the sale by the president’s ownership entity.

This year, Trump’s ownership company will be responsible for the full tax bill at the former Barry house. Under the new estimates, the house and side lot were assigned a total market value of $13.9 million — the same as its taxable value. The proposed tax bill, including assessments, for both properties is $234,979.

The two other Palm Beach houses used by the president and his family are across the coastal road from his sister's former house. Both were purchased in 1993. Add in a vacant parcel — measuring about a fifth of an acre — next to one of them, and their preliminary tax bills total $226,236.

The larger of the two houses, at 1094 S. Ocean Blvd., has a proposed taxable value of about $10 million, up from its final valuation of $9.27 million in 2018. The other house, next door at 124 Woodbridge Road, has a taxable value of about $3.11 million, up from its final valuation of $2.83 million last year.

The grand total of estimated taxes for Trump-related properties in Palm Beach is $983,055.

Golf club tax revenue

At the Trump International Golf Course off of Congress Avenue and Summit Boulevard , only the clubhouse generates tax revenue under a longtime lease agreement Trump negotiated with the county and Palm Beach International Airport. The clubhouse parcel there would be billed $165,053 — based on its value of about $9.3 million — if this week’s tax estimates hold steady. Last year, the clubhouse had a final taxable value of $9.22 million, records show.

The club's courses include 18 holes on 213 acres and a nine-hole course on 62 acres. The two golf courses are valued together, according to the preliminary figures, at about $8.12 million, down from their final valuation of $9.19 million last year, the appraisals made public Monday show. Although the golf club's property generates relatively little in taxes, it does provide rental income to the county and the airport. Those leases generate more than $900,000 a year, county records show.

The three parcels that comprise the Trump National Golf Club in Jupiter, meanwhile, are estimated to add another $336,578 in property taxes for 2019, based on a taxable value of about $16.3 million, the same as its market value. The 183-acre property is at Alternate A1A and Donald Ross Road.

In November, attorneys for Trump reached a settlement with the county property appraiser, which agreed that the Jupiter golf course had been overvalued in the tax rolls for 2013 through 2016. The county issued a refund, but the amount was not immediately available Monday.

Property owners who disagree with the values assigned to their properties can negotiate directly with the appraiser's staff. But if the matter isn't resolved, owners have until Sept. 13 to file an appeal with the state-authorized Value Adjustment Board.
