Puddle of Mudd Singer Wesley Scantlin -- Taxes? What Taxes?

Puddle of Mudd front man Wesley Scantlin must have been a pretty busy man in 2009 -- because the government claims he forget to pay more than $60k in federal AND state taxes that year.

According to documents filed with the Los Angeles County Recorder's Office, Scantlin screwed Uncle Sam out of $44,726.23 ... and stiffed CA to the tune of $17,323.51.

A source close to Scantlin tells us the matter is being taken care of -- but had no further comment.
