The Office producer Paul Lieberstein revealed in March that plans were underway for a new series set on Dwight's beet farm. Wilson will also continue to make appearances in The Office.
Viewers will get their first look at the spinoff in a season nine The Office episode which introduces the Schrute family, reports TVLine.
The extended Schrute family will include Dwight's younger sister Fannie Schrute, a single mother whose left-leaning political views make her the opposite of her brother.
Fannie's 9-year-old son Cameron will find himself torn between his mother's relaxed views on society and uncle Dwight's stern rules.
Dwight's younger brother Jeb, an unmotivated former Bigfoot hunter, will also be on hand to reunite with Dwight and Fannie at Schrute Farm.

The siblings' great uncle Heinrich Manheim, who might have World War II-era Nazi ties, will be making appearances on the sitcom as well.
Casting is apparently underway for all these roles. It is not yet known whether Parks and Recreation showrunner Michael Schur will be reprising his role as Dwight's cousin Mose.
A premiere date has not yet been announced for The Farm, but the show is expected to debut in early 2013.
It was also reported last week that BJ Novak will not work full-time on The Office in season nine, but will make guest appearances.
