The actor most famous for playing Ron Weasley will be required to pay millions back in taxes after using a loophole once employed by the Beatles.

Rupert Grint must pay £1.8 million (about $2.3 million) to the U.K.'s tax agency after incorrectly classifying his 'Harry Potter' residuals as a capital asset instead of income, a British judge ruled this week.

Grint was ordered to pay the money in 2019 after the U.K. tax agency said he had wrongly classed 4.5 million pounds in residuals from the movies as a capital asset rather than income, which is subject to a much higher tax rate.
