The Duke and Duchess of Sussex, who are estimated to have a joint fortune of £20 million, live in a mansion in Montecito, California. Meghan is a US taxpayer, but Harry will have to declare his income

Prince Harry could face a huge tax bill unless he takes a break from his £11million mansion in the US, it has been reported.

Harry, his wife Meghan and son Archie moved to Los Angeles in early May after leaving a rented mansion in Vancouver, Canada.

They were first said to be staying at a mansion owned by TV producer Tyler Perry on May 7.

This means Harry has been in the US for at least 151 days and, if he reaches 183 days there, he is liable to pay taxes.

Top LA tax lawyer David Holtz last night said: “You can safely assume that someone at the Internal Revenue Service is looking very closely at him. This is a big deal.”
