The visit will take place from September 17 to 19.
"His Majesty the King will host the President and Mrs Trump at Windsor Castle," the palace said in a statement, adding that further details would be announced in due course.
Trump said last month he had agreed to meet Charles after British Prime Minister Keir Starmer handed him a handwritten letter from the monarch in the Oval Office.
The U.S. president will be the first elected political leader in modern times to be hosted for two state visits by a British monarch.
The late Queen Elizabeth welcomed Trump to Buckingham Palace for a three-day state visit in June 2019 during his first term in office, during which he had a private lunch with the sovereign and had tea with Charles, who was then heir.
Starmer and Trump are also due to meet in Scotland later this month, a source told Reuters last week, with details including the specific date yet to be finalised.
The two leaders have developed a warm relationship in recent months, and last month signed a framework trade deal on the sidelines of a G7 meeting that formally lowered some U.S. tariffs on imports from Britain.
In May, Canadian Prime Minister Mark Carney criticised Britain's invitation to Trump for a state visit, saying it undermined his government's effort to project a united front against the U.S. president's talk of annexing Canada.
Trump's past visits to Britain have attracted large protests, with his 2018 trip costing police more than 14 million pounds ($18.88 million) as 10,000 officers were deployed from all over Britain. Most Britons have an unfavourable view of the president, according to opinionpolls.
State visits are usually pomp-laden affairs featuring an open-top carriage trip through central London and a banquet at Buckingham Palace.
