Each of the Trumps filed a "declaration of domicile" saying that the Mar-a-Lago Club, Trump's resort in Palm Beach, will be their permanent residence. Donald Trump changed his primary residence from Manhattan to Mar-a-Lago - the exclusive golf club that he has referred to as the "winter White House".
Mr. Trump moved into Trump Tower at 521 Fifth Avenue when it opened in 1983.
President Trump, a born and bred New Yorker, whose brash and boisterous persona has reflected the popular image of his native city is pulling up stakes.
Donald Trump is now a Florida man.
He added, "I think he knows that he alienated New Yorkers, and his philosophy is repugnant to New Yorkers".
Although Florida leans more Republican than New York, Trump won't find friends everywhere in the Sunshine State - the U.S. lawmaker who represents Palm Beach, Lois Frankel, is a Democrat who backs Trump's impeachment.
"I love NY, but New York can never be great again under the current leadership of Governor Andrew Cuomo (the brother of Fredo), or Mayor Bill DeBlasio", Trump said, also including an apparent hit at CNN's Chris Cuomo. "It's not like @realDonaldTrump paid taxes here anyway ... He's all yours, Florida".
In addition to taxes, Trump may also be considering Florida's key importance to his 2020 reelection campaign.
Earlier this month a judge ordered Mr Trump to hand over eight years of his tax returns to NY investigators. New York Lieutenant Gov. Kathy Hochul said the changes decreased revenues and increased taxes on the middle class. NY imposes a top estate tax rate of 16% for estates larger than $10.1 million.
But in his farewell posts - a 2019 rendition of "Goodbye to All That" - Trump said he would still "cherish NY, and the people of NY". The state Department of Taxation and Finance will go to great lengths to keep wealthy residents on their tax lists.
The documents filed in the West Palm Beach courthouse give no reason for the move. "I Love New York!" he concluded.
"The move to Florida could save him a lot of money", said commentator and former aide to President Bill Clinton Keith Boykin on Twitter, "but we don't know how much because he won't release his tax returns".
New York City Council Speaker Corey Johnson had the same message for Trump.
