TRENTON — A Morristown man who is among the state's "Top 100 Tax Debtors" has been sentenced to five years probation contingent on his paying $500 a month for 25 years, authorities said Thursday.

Gregory Cobbs, 51, who pleaded guilty in March to failure to pay taxes before Superior Court Judge Timothy Lydon, could be subject to a 364-day sentence in the Mercer County jail if he falls behind in paying the $150,000 restitution to the Division of Taxation, the Mercer County Prosecutor's Office said.

Cobbs is the first person on the state's "Top 100 Tax Debtors" list to be convicted under the state's failure to pay taxes statue, a Treasury spokesman said. Cobbs failed to respond to attempts to resolve his tax issues prior to being charged criminally, prosecutors said.

Cobbs initially owed $220,000 in personal income taxes, but that number ballooned to $386,000 with penalties and interest.

The Division of Taxation could still pursue the balance of his owed taxes through civil action, according to the prosecutor's office.
