Instead of Omarion worrying about what Raz B has to say about him and Marques Houston….he needs to be worrying about why he owes the IRS over $100,000 in back federal taxes!

Peep the full story below…

The R&B singer is apparently struggling to keep up with his tax payments and now owes the Internal Revenue Service (best known as the IRS or “Uncle Sam”) $110,000.

Omarion (known to the government as Omari Grandberry) was hit with his first lien for nearly $50k back in August of 2009 by the LA County Recorder of deeds. He also received another bill for an undisclosed amount a few months later in October, before receiving another one amounting to nearly $40K from the Orange County Recorder of Deeds in May of this year.

The former B2K member even tried to file for Chapter 13 bankruptcy at the start of the year, but the case was dismissed.

The back taxes Omarion owes date back to 2003 when he was with B2K.
