No South Dakota statute licenses concrete, flatwork, or foundation contractors. The state obligation is tax registration: anyone paid for construction work — DOR's self-contractor guidance names concrete work specifically — must hold a contractor's excise tax license and pay 2% on gross receipts (SDCL 10-46A-1, -15).
DOR treats concrete driveways, sidewalks, patios, and retaining walls as excise-taxable realty improvements, as well as concrete floors. Materials are purchased tax-paid at the 4.2% state rate plus municipal tax. Local building permits and inspections — and any local licensing — apply where you pour.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
South Dakota has no state contractor license for this trade, so cities and counties are free to add their own contractor licensing, registration, and permit rules. State law requires contractors to post their DOR contractor's excise tax license number with the building permit for a realty improvement project (SDCL 10-46A-12.1), and SDCL 10-46A-11 authorizes a municipal contractors' excise tax of up to one-half percent. Electrical and plumbing licensing remain statewide, though both chapters allow stricter local rules (SDCL 36-16-35, 36-25-16).
The local offices section below names the exact permit desk for every South Dakota county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
DOR's self-contractor tax fact lists concrete work among the jobs that make you a contractor needing a CET license.
On mixed jobs, if 25% or more of the contract value is excise-taxable work, DOR lets you charge CET on the whole contract.
The state rate on the materials you buy goes from 4.2% to 4.5% on July 1, 2027 (SDCL 10-45-2).

Engaging in business subject to the contractor's excise tax without obtaining the license is a crime; so is failing to file returns or pay the tax within 60 days of the due date.
Keeping on without a license after DOR notifies you in writing that you are a contractor subject to the tax (unless you apply within three days), or working after revocation, is a felony.

Pending verification: That DOR charges no fee to issue a contractor's excise tax license — SDCL 10-46A-16 says a license is valid 'without further payment of fees' and the January 2026 CET guide lists no fee, but neither states expressly that issuance is free · Municipal contractor licensing, registration, or bonding in Sioux Falls, Rapid City, and other South Dakota cities (outside the scope of this state-level record) · Whether any municipality currently levies the local contractors' excise tax of up to one-half percent authorized by SDCL 10-46A-11
