Pamela Anderson allegedly owes almost $500,000 in back taxes
The former Playboy model and `Baywatch` actress was sent a demand for $493,144, largely in Personal Income Tax in April last year and has been named by the California Franchise Tax Board as still owing the sum in its annual list of taxpayers who owe the board over $100,000.
Pamela, 42, and her lawyer, Robert T. Leonard, have declined to comment on the claims.
However, the actress has previously defended herself against financial "mistakes".
She said: "Mistakes may have been made in calculating taxes owed."
The star also faces a legal battle in New York, with US clothing firm Maggy London International filing proceedings over the name of Pamela-s own fashion line.
The firm claim the actress ignored their demands to change the name of her A*Muse clothing label, launched earlier this year - insisting it infringes the trademark of their Muse clothing line, which they registered in 2002.
Last year, it was rumoured Pamela was in financial difficulties, after building companies said she owed them $1 million for renovations made on her house in Malibu, California.
However the blonde beauty issued a statement at the time rubbishing the claims.
She said: "I`m financially secure. It is true that I am in a dispute with some of the contractors working on my home.
"My lawyers are reviewing the work done to see if the bills are fair. If they are, they`ll be paid. If they aren`t, they won`t be."
Singer Ron Isley of the Isley Brothers is also on California Franchise Tax Board-s list, owing over $303,000.
