It's almost Tax Day. It causes us to groan, grumble and moan. On the bright side be thankful you aren't Ozzy and Sharon Osbourne! TMZ is reporting that they owe more than $1.7 million to the IRS in back taxes! Ouch!

The IRS filed a document last Monday with the L.A. County Recorder's Office, claiming Ozzy and Sharon owe $718,948.25 for the 2008 tax year, and $1,024,175.03 for 2009.

Sharon had a tax lien issue in 2009, when she owed $23,000 to the State of California for the 2007 tax year.

And Kelly also has tax issues ... last month the State of California filed a lien against her for $34,000.

No comment so far from the Osbourne's rep.
