Tori Spelling & Dean McDermott Are In Danger Zone with the Feds

Tori Spelling is practically swimming in overdue bills ... to the tune of over $1 million.

Tori and hubby Dean McDermott were slapped with a federal tax lien for a whopping $707,487.30 in unpaid taxes, according to docs obtained by TMZ. And that's JUST for 2014.

The good news, you could say, is the couple made enough that year to owe that kinda tax -- but they've got lots of other financial problems.

American Express sued Tori back in January claiming she owes $37,981.97. And don't forget ... Tori and Dean have a $259k bill from the State of California.
