Getting your South Dakota license starts here...
South Dakota takes a different approach than most states: there’s no general contractor license at all. Construction businesses instead register for a Contractor’s Excise Tax License and pay a 2% tax on gross receipts, with no exam or bond attached. Electricians and plumbers are licensed separately through their own state commissions, each with independent exams and renewal cycles. Because there’s no general trade exam, NASCLA reciprocity doesn’t apply here. Cities like Sioux Falls and Brandon add their own local licensing on top. Contractor Licensing Inc. helps you sort out exactly which of these apply to your business.
South Dakota Contractor License Requirements & Application Help
South Dakota is one of the lightest-touch states in the country for general contractors: there's no statewide general contractor license. Instead, construction work is regulated through a Contractor's Excise Tax License from the Department of Revenue, while electricians and plumbers are licensed separately by their own state commissions, and cities like Sioux Falls layer on their own local licensing.
Contractor Licensing Inc. helps you sort out which of these actually apply to your business. See our full National Contractor Licensing guide for requirements in every state.
Quick Answer
- South Dakota does not license general contractors at the state level — no state exam, no state general contractor bond.
- Construction businesses instead register for a Contractor's Excise Tax License and pay a 2% tax on gross receipts from construction services.
- Electricians are licensed by the South Dakota Electrical Commission (Apprentice, Journeyman, Electrical Contractor, Class B Electrician).
- Plumbers are licensed by the South Dakota Plumbing Commission across eight categories, with licenses expiring annually on December 31.
- NASCLA reciprocity doesn't apply — there's no state general contractor exam for it to replace.
- Sioux Falls and Brandon require their own local contractor licenses and bonds on top of state-level requirements.
South Dakota's Contractor's Excise Tax License
Rather than licensing contractors by trade or classification, South Dakota regulates construction activity through its Contractor's Excise Tax (SDCL 10-46A). Anyone who enters into a contract for construction services, or who is otherwise engaged in the construction, building, installation, or repair of a fixture to real property, must obtain a Contractor's Excise Tax License from the South Dakota Department of Revenue and remit a 2% excise tax on gross receipts from that work — on top of any applicable state and municipal sales tax. This applies to prime contractors and subcontractors alike, and the license is issued through the Department's online Tax License Application system.
Because this is a tax registration rather than a trade credential, there is no exam, no continuing education, and no state bond tied to the excise tax license itself. Contractors still must file excise tax returns monthly, due by the 20th of the following month, with electronic payment due by the 25th.
South Dakota Electrical Commission
Apprentice Electrician
Works under the direct employment and supervision of a licensed electrical contractor while logging hours toward the Journeyman exam.
Journeyman Electrician
Requires four years (8,000 hours) as a licensed apprentice before sitting for the Journeyman exam; hours must be logged under a licensed employer to count.
Electrical Contractor
Requires an additional two years (4,000 hours) as a Journeyman — including at least 2,000 hours of commercial work — before the Contractor exam, plus a bond application.
Class B Electrician
A separate, bonded electrician license category with its own exam, distinct from the full Electrical Contractor credential.
Continuing Education
Every renewal requires 16 hours of continuing education, at least 8 of which must be code hours; only 8 hours may come from pre-approved online courses.
Licensing Authority
The South Dakota Electrical Commission, under the Department of Labor and Regulation, issues and renews all electrical licenses statewide.
South Dakota Plumbing Commission
The South Dakota Plumbing Commission licenses plumbers and related trades across eight categories: Plumbing (Contractor, Plumber, Third-Year Apprentice), Sewer and Water, Appliance, On-Site Wastewater System Installer, Manufactured and Mobile Home, Underground Irrigation, Water Conditioning, and Apprentice licenses across each specialty. A Plumbing Contractor license requires six years of experience as a plumbing contractor, plumber, or plumber's apprentice — including at least two years at the contractor or plumber level — along with 1,900 hours of documented work per year. Specialty categories such as appliance, irrigation, water conditioning, and mobile home installation generally require one year as an installer to reach contractor status, and two years as an apprentice to become an installer.
All South Dakota plumbing licenses expire annually on December 31 and require proof of completed continuing education before the following year's renewal is processed. Third-year apprentice plumbers must pass a state-administered exam before working unsupervised on single-family dwellings.
No Statewide Trade Exam for General Construction
Because South Dakota doesn't issue a general contractor license, there is no statewide construction trade exam for general building work — only the specialty boards (electrical and plumbing) run their own exams. This means NASCLA reciprocity does not apply in South Dakota: there's no general contractor exam for an accredited NASCLA score to substitute for. Electricians and plumbers instead go through the Electrical Commission's and Plumbing Commission's own exam and reciprocity tracks described below.
South Dakota Contractor License Reciprocity
Electrical — 14-State Reciprocal List
South Dakota's Electrical Commission recognizes out-of-state licenses from Alaska, Arkansas, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, Texas, and Wyoming — though the license level covered (Journeyman, Master, or Electrical Contractor) varies by state. Applicants must have earned the license by examination in that state and held it in active status for at least one year.
Plumbing — Case-by-Case Review
The Plumbing Commission doesn't publish a fixed reciprocity list. Instead, it reviews each applicant individually, comparing whether they were licensed by examination in their home state, whether that state's plumbing code is equal to or exceeds South Dakota's, and whether the applicant's actual work experience complies with that code. The commission may request affidavits as part of its investigation.
Sioux Falls & Brandon Require Their Own City Licenses
On top of state-level excise tax registration and any applicable trade license, South Dakota's larger municipalities license contractors locally. Sioux Falls issues its own contractor licenses across categories including Commercial Building, Residential Building, Electrical, Class B Electrical, Plumbing, Mechanical, Refrigeration, Fire Alarm, Fireplace, Landscape Irrigation, Sign Wiring, and Sign and Outdoor Advertising Contractor — each requiring its own bond, typically $10,000 (Residential Building runs $20,000). Brandon, SD also requires a separate local contractor license and bond. Before bidding work in any South Dakota city, confirm whether that municipality runs its own licensing program in addition to the state's excise tax license.

Reciprocity
South Dakota offers limited reciprocity for certain plumbing and electrical licenses with neighboring states. Reciprocity agreements allow qualified licensees from approved states to obtain a South Dakota license without retaking technical exams, provided they meet all other requirements (insurance, bonding, fees).
