Beaufort County Treasurer Doug Henderson will not seek re-election this year.
Instead, he will support deputy county treasurer Maria Walls in her bid for the seat.
Henderson will retire at the end of his term in June 2015, he said at a news conference Wednesday in Beaufort.
"I'm announcing at this time because it will allow any other candidates to file and run in the primary in June and the election in November," Henderson said.
Never miss a local story.
The filing period for candidates to enter this year's congressional, state and local elections opens at noon Sunday, according to the S.C. State Election Commission's website. The period closes at noon March 30.
Walls said she will file for the treasurer's race Monday morning and hopes her experience working with Henderson for the past three years proves her abilities to voters.
"There's nothing like hands-on training," she said.
Walls was part of a new crop of staff members Henderson hired after unseating 20-year incumbent Joy Logan in the 2010 Republican primary. Henderson did not face opposition in the general election.
At the time, the Treasurer's Office was the subject of a Beaufort County Sheriff's Office investigation to find missing money from a delinquent tax sale. The inquiry ended in charges against one office employee, who was convicted of embezzling more than $210,000, and calls for Logan's resignation.
County Council members and county administrator Gary Kubic say Henderson has made the Treasurer's Office more efficient and better-protected from staff errors or malfeasance.
"I ran for this position to fix the many problems that were obvious and well-documented," Henderson said. "However, I did it (ran) not to be a career politician. I did it to fix those problems."
By the end of his term, Henderson said he will have accomplished all of his goals and will be ready to step aside.
Henderson previously spent 35 years in the banking industry and a six-year stint in the county Assessor's office to perform property assessments. Now he's ready to try his fourth attempt at retirement.
"I'm going fishing," he said.
