Governor Dannel Malloy will appoint Scott Jackson, commissioner of the state Department of Labor, to lead the Department of Revenue Services.
Jackson succeeds Kevin Sullivan, who served as commissioner for eight years before departing last month for a position in the private sector.
Malloy is appointing DOL deputy commissioner Kurt Westby to lead the labor department.
"Both Scott and Kurt have provided exceptional service with the Department of Labor and I am certain that their transition into their new roles will be a seamless move," Malloy said in a June 1 statement.
Jackson, the mayor of Hamden from 2009 to 2015, was appointed DOL commissioner in 2016 after a brief stint with the state Office of Policy and Management.
"I look forward to joining the dedicated public servants who staff DRS and continue the exceptional work initiated by Commissioner Sullivan," Jackson said.
"I know that the Department of Labor is in good hands under the leadership of Kurt Westby, and I am excited about the opportunity to bring to DRS the customer-focused philosophy and inclusive approach we worked hard to advance at CTDOL."
Westby, a former consultant with the Service Employees International Union who also held leadership roles with both the SEIU and Connecticut AFL-CIO, was appointed deputy commissioner at the labor department in 2016.
Malloy said Jackson and Westby will begin their new roles later this month.
