Manchester — A certified public accountant from Claremont has been indicted by a Hillsborough County grand jury on a felony count of conspiracy to commit tax evasion.

Darvi Rosenberg, 62, allegedly helped a Manchester restaurateur — who also is a state representative and city alderman — evade tax obligations, according to a news release issued earlier this week.

“Among other alleged acts, Mr. Rosenberg produced fraudulent records to auditors, attempted to impair or impede the Department of Revenue Administration’s audit and also caused false or misleading statements to be made to DRA auditors,” the release from the New Hampshire Attorney General’s Office and the Department of Revenue Administration states.

Rosenberg worked as Thomas Katsiantonis’ accountant and tax preparer for Katsiantonis’ two Manchester-based businesses, Grand Slam Pizza II and Tommy K’s Restaurant and Bar, as well as Katsiantonis himself, court documents indicate.

Among other allegations, Katsiantonis, as owner and operator of Grand Slam Pizza II, allegedly kept more than $277,000 in monthly meals and rental tax payments between June 2011 and January 2017. As owner of Tommy K’s, Katsiantonis allegedly kept more than $146,000 in like payments between May 2015 and January 2017.

The money Katsiantonis obtained from customers should have gone to the state of New Hampshire, but he “dealt with the money as if it were his own,” according to court documents.

Katsiantonis, a Democrat who has served in the New Hampshire House for six terms, has been indicted on four counts of theft, four counts of tax evasion and counts each of falsifying physical evidence and conspiracy to commit tax evasion.

Rosenberg, through a secretary at his Claremont office, referred comment to his attorney Philip Utter, of Manchester. A message left for Utter wasn’t returned.

Both men will be arraigned on July 21 in Hillsborough Superior Court North in Manchester.
