South Dakota contractor license lookup

South Dakota contractors must hold a free contractor's excise tax license from the Department of Revenue. It is a tax license, not a skills license; ask your city or county about local rules. (source: SD DOR: Contractor's Excise Tax (opens in a new tab), source: SD DOR: License Requirements (PDF) (opens in a new tab))

How: We couldn't confirm a public search. Ask for the contractor's excise tax license number, which appears on prime contractor exemption certificates. (source: SD DOR: Contractor's Excise Tax (opens in a new tab))
