The UK royal family faces a tax "nightmare" as US officials examine whether Meghan and Harry owe them a slice of their multi-million pound fortune.
The Duchess of Sussex is still an American citizen, so has to pay tax in the US, and this could extend to anyone else she draws money from, including her husband.
This could deplete both her $5 million US fortune and Prince Harry's main source of private wealth, a 300,000-pound-a-year trust fund on which he pays UK income tax.
The probe could even extend to the Queen and Prince Charles as they provide funding for the couple, aides told the Sunday Express, which reported that the royals are set to employ a team of US financial consultants to deal with the issue.
'We're looking at a level of financial exposure the Royal Family has never had to face before,' one of the aides said.
The US Internal Revenue Service is known for being extremely strict in tracking down people they believe owe them money.
Kensington Palace declined MailOnline's request for comment.
