Rupert Grint has been ordered to pay over a MILLION in owed taxes

It looks like Harry Potter star Rupert Grint is in big trouble.

It's after coming to light the Rupert has been ordered to pay £1.3 MILLION in owed taxes… and he's blaming his dad for it.

The 27-year-old put his father and accountant in charge of his finances, and after some numerical trickery, Clay & Associates changed his accounting date so that 20 months of income would be taxed in the calendar year of 2009-2010.

So, all in all, eight months of Rupert's income hasn't been declared.

In the time that he didn't pay taxes, the rate went from 40 percent to 50 percent, so he's really having to pay for it now.

According to Hollywood Life, Rupert tried desperately to appeal the £1.3m ruling, claiming he had practically no awareness that it was going on.
