South Dakota prevailing wage and certified payroll rules

South Dakota has no state prevailing wage law. Jobs paid only with state or local money carry no state wage rates, but federally funded or assisted construction contracts over $2,000 fall under Davis-Bacon.

South Dakota does not have a state prevailing wage law. The U.S. Department of Labor includes South Dakota in its list of states without one, with no repeal year shown. In practice, that means two kinds of public work in the state. A job paid only with state, county, city, or school district money has no state wage schedule. A job with federal funding or assistance on a contract over $2,000 is covered by the Davis-Bacon Act, with federal rates and weekly certified payroll.

Why federal dollars matter so much in South Dakota

In a state with small towns and long distances, a lot of public infrastructure is built with help from federal grants and loans. Water and wastewater upgrades, rural roads, community buildings, and housing often carry some federal money. The Department of Labor says the Related Acts extend Davis-Bacon wage rules to construction assisted through federal grants, loans, loan guarantees, and insurance. So the owner on the contract may be a town of a few hundred people, while the wage rules come from Washington.

Here is how that plays out. A small excavation and utility contractor near Pierre bids a $420,000 water main replacement for a town. The town is the owner, but part of the funding is a federal loan. The contract includes a wage determination for heavy construction in that county, federal labor standards clauses, and a requirement for weekly payroll. The same crew next month on a privately funded farm drainage job is under none of that.

Pricing a Davis-Bacon job when you usually do not

The wage determination lists each classification with a base hourly rate and a fringe benefits amount. If you do not offer benefits, you pay the fringe in cash on the check, which usually raises taxable wages and the payroll costs tied to them. If you do offer bona fide benefits, you may be able to take a fringe benefit credit for part of the obligation.

  1. Find the determination named in the bid documents. The Department of Labor posts them on SAM.gov by state, county, and construction type.
  2. Map each crew member to a classification on that determination, not to your internal job titles.
  3. Build an hourly cost for each classification: base rate, fringe (cash or plan), and your labor burden.
  4. Add time for weekly payroll preparation and review. It is real office labor on a small company.
  5. Plan apprentices carefully, since apprentice rates come with conditions on Davis-Bacon work; read apprentice rules on prevailing wage projects first.

Certified payroll on South Dakota federal jobs

South Dakota has no state certified payroll form or portal. On Davis-Bacon work, the Department of Labor says contractors and subcontractors must submit payroll information every week with a signed Statement of Compliance. The WH-347 is a convenient format, and its use is optional, but the content it asks for is required. When a federal agency is a party to the contract, payrolls go to that agency. On federally assisted jobs, they go to the applicant, sponsor, or owner, which keeps them for the funding agency.

South Dakota versus states with their own laws

With no state law, South Dakota contractors deal with a single federal system. Compare that with Rhode Island, where state rules reach contracts over $1,000, or Oregon, which has its own rate books, monthly state payroll filings, and penalties on top of any federal requirements. Neighboring North Dakota and Iowa are also on the Department of Labor's no-law list.

Before bidding public work in the state, also check South Dakota contractor license requirements, South Dakota mechanics lien rights, and the South Dakota prompt payment rules for getting paid.

Smart Business Automator tracks time by classification on federally funded jobs and builds the weekly certified payroll from those entries, which helps a small office handle the occasional Davis-Bacon contract. See certified payroll automation.

Frequently asked questions

Does South Dakota have a prevailing wage law?

No. The U.S. Department of Labor lists South Dakota among the states without a prevailing wage law. Federal Davis-Bacon rules still apply to federally funded or assisted construction contracts over $2,000.

Do South Dakota towns have to pay prevailing wage on water projects?

Not under state law. If the project is funded or assisted with federal grants or loans that carry Davis-Bacon through a Related Act, and the contract is over $2,000, federal prevailing wages and weekly certified payroll apply.

Where can I find South Dakota prevailing wage rates?

The state does not publish construction wage rates. For federally covered work, use the Davis-Bacon wage determination named in the contract, available on SAM.gov by county and construction type.

Who receives certified payroll on a South Dakota federal job?

The federal agency if it is a party to the contract. Otherwise the applicant, sponsor, or owner, such as the town or district, which keeps the payrolls for the funding agency.
