Prompt payment

Wyoming prompt payment act and retainage rules

Wyoming agencies must pay construction invoices within 45 days of a correct notice of amount due or pay 1.5 percent interest per month, unless the contract says otherwise. Public entities may hold no more than 5 percent retainage, released on the 41st day after a published substantial completion notice. Private work has no prompt pay statute.

Wyoming's prompt payment act is one sentence long. W.S. 16-6-602 says that, except as provided by contract, an agency buying goods or services from a nongovernmental entity must pay within 45 days after receiving a correct notice of the amount due, or pay interest from the 45th day at 1.5 percent per month until paid in full. The definition in 16-6-601 expressly counts construction services and covers both state agencies and political subdivisions. Retainage on public work is capped at 5 percent under 16-6-702, and its release is tied to a published notice process in 16-6-116. Wyoming has no private-project prompt pay statute.

The 45-day rule for public owners

Section 16-6-601 defines an agency as any department, agency or other instrumentality of the state or of a political subdivision, so the same rule reaches the state, counties, cities, towns and school districts. Services include construction services. The interest rate is written into the statute, 1.5 percent per month on the unpaid balance, which works out to 18 percent a year before any compounding question.

Two things can turn the rule off. The first is the contract: the section opens with "except as provided by contract," so a public owner's general conditions can set a different payment schedule. Read them at bid time. The second is a good faith dispute over the agency's obligation to pay all or part of the account.

Example: a mechanical contractor sends a school district a correct $90,000 pay request that the district receives on March 1. If the contract is silent on timing, payment is due within 45 days. If the district pays a month late, interest at 1.5 percent per month on $90,000 is about $1,350.

Retainage on Wyoming public work

Under 16-6-702, a public entity must authorize partial payments as the contract stipulates when the contractor is performing satisfactorily, and may retain no more than 5 percent of the calculated value of work completed. There is no 50 percent step-down in the statute. The money does not just sit in the owner's general fund: it is held in an account in the contractor's name that has been assigned to the public entity.

  • Early release: if progress is satisfactory in all phases, the contractor can ask in writing for payment from the withheld amount. The owner must find satisfactory and substantial reasons and get written approval from the surety first.
  • Interest on held funds: on contracts over $50,000, if the general contractor asks, the public entity must enter an interest-bearing deposit agreement with a depository the contractor designates, after notice to the surety (16-6-704). Interest and income go to the contractor (16-6-705), and custodial costs cannot be charged to the public entity.
  • Takeover: if the public entity has to finish the job itself, retainage first pays for completion and any balance goes to the contractor or its creditors (16-6-703).
  • Federal funds: these rules give way when federal or other funding sources impose inconsistent retention requirements (16-6-706).

Substantial completion notice and the 41st day

Section 16-6-116 sets the release mechanics. The public entity issues a certificate of substantial completion, then publishes notice once a week for two consecutive weeks in the newspaper published nearest the job and posts it on the state procurement website or its own site. The notice must state the exact date the general contractor is entitled to payment: the 41st day after the notice was first published and posted. On that day the owner pays the retainage and any other amount due, less amounts withheld for incomplete or nonconforming work. Those withheld amounts are paid at final completion.

There is a catch for the GC. Section 16-6-117 bars any payment under 16-6-116(a) until the contractor files a sworn statement that all claims for labor, material and supplies have been paid. Disputed sub claims are listed on the statement, and the sub can file them against the general contractor's surety bond. So if a notice first runs June 3, payment is due July 14, but only if the sworn statement is on file. Unpaid subs should know the publication date and get their claim in writing before the 41st day.

Subs, private jobs, and pay-if-paid

No Wyoming statute sets a prime-to-sub payment deadline, on public or private work, and there is no private-project prompt pay law. Husch Blackwell's July 2020 survey reports that Wyoming has not addressed pay-if-paid clauses, so enforceability is unsettled; have counsel review one before you sign. On private jobs, lien rights carry most of the weight, so track the Wyoming mechanics lien deadlines alongside your billing.

Smart Business Automator keeps the substantial completion date, the 41st-day payment date and each sub's paid status on the job record, so the sworn statement is not what holds up the money. See construction accounts receivable automation.

Frequently asked questions

How long does a Wyoming public agency have to pay a contractor?

Forty-five days after receiving a correct notice of the amount due, under W.S. 16-6-602, unless the contract provides otherwise. Late payments earn 1.5 percent per month from the 45th day, unless there is a good faith dispute.

What is the retainage cap on Wyoming public projects?

Five percent of the calculated value of work completed, under W.S. 16-6-702(b). The statute has no step-down at 50 percent.

When is retainage released on a Wyoming public job?

On the 41st day after the substantial completion notice is first published and posted under W.S. 16-6-116, less amounts held for incomplete work, and only after the contractor files the sworn statement that labor and material claims are paid.

Can a Wyoming contractor earn interest on retainage?

Yes. On public contracts over $50,000, if the general contractor requests it, the public entity must enter an interest-bearing deposit agreement with a depository the contractor designates, and the interest is paid to the contractor.

Does Wyoming have a prompt payment law for private construction?

No. Private payment timing and retainage are set by the contract.
