Prompt payment

Utah prompt payment act and retainage rules

Utah regulates retention more tightly than payment timing. Utah Code § 13-8-5 caps retention at 5 percent on public and private jobs, requires an interest-bearing account, and sets a 45-day release. The Utah Prompt Payment Act (Title 15, Chapter 6) gives state agencies 60 days to pay when the contract is silent.

In Utah the prompt payment act that applies to most contractors is really a retention statute. Utah Code § 13-8-5 covers construction contracts between owners or public agencies, original contractors, and subs entered on or after July 1, 1999. It caps retainage (Utah says retention proceeds) at 5 percent of each payment and of the total price, makes the owner hold it in an interest-bearing account, and requires release within 45 days of a qualifying billing statement. On straight payment timing, the Utah Prompt Payment Act, Title 15, Chapter 6, sets a 60-day default for state agencies, with interest at 2 percent above the IRS refund rate.

State agency payments under Title 15, Chapter 6

Section 15-6-2 says a state agency that buys property or services under a contract pays on the date the contract sets or, if none, within 60 days after it receives the invoice. Section 15-6-3 adds interest at 2 percent above the rate the Internal Revenue Service pays on refund claims. The rate is set quarterly and applied on a per annum basis, starting the day after the contract due date or on the 61st day after the invoice. Interest left unpaid at the end of a 60-day period is added to principal and earns interest too. The chapter speaks to state agencies; counties, cities, and school districts may have their own payment terms, so check the bid documents.

Retention under Utah Code § 13-8-5

  • Who it covers: owners and public agencies, original contractors, and subs, on contracts entered on or after July 1, 1999. It does not apply to construction lenders, and on mixed projects it reaches only the nonresidential share.
  • Cap: no more than 5 percent of any payment, and total retention may not exceed 5 percent of the total construction price. If the owner holds less than 5 percent, lower tiers must use that same lower percentage.
  • Account: retention goes into an interest-bearing account and is tracked separately. It is held in constructive trust, protected from assignment and garnishment.
  • Release: due within 45 days after a billing statement, measured from the latest of events such as receipt of the billing statement, a certificate of occupancy or final acceptance, permitted occupancy, or the contractor's acceptance of final pay quantities. Partial occupancy triggers a proportional partial release. The billing statement must include lien releases or waivers.
  • Withholding at closeout: an owner may hold funds reasonably needed to cure a breach and, after substantial completion, up to twice the fair market value of unfinished work, described in writing within 45 days.
  • Down the chain: a contractor or sub that receives retention pays each sub its share within 10 days.
  • Penalties: the prevailing party in a collection action recovers attorney fees and costs, and knowingly and wrongfully withholding costs 2 percent per month on the amount withheld. No party may require another to waive the section.

What Utah law does not cover here

The statutes reviewed for this page set no general payment deadline for private owners and no general deadline for a prime to pass progress payments to subs. Those terms come from the contract. They also do not address pay-if-paid clauses, so read the subcontract closely and compare it with your lien deadlines in the Utah mechanics lien guide.

A quick example. A mechanical sub on a $2 million office build is owed 5 percent retention on its $400,000 subcontract, or $20,000, plus its share of the interest. Once the GC gets the release, that money is due to the sub within 10 days. Smart Business Automator tracks retention and interest owed by sub in construction accounts receivable automation.

Frequently asked questions

What is the retainage limit in Utah?

Utah Code § 13-8-5 caps retention at 5 percent of any payment and 5 percent of the total construction price, on both public and private covered contracts.

Does Utah require retention to be held in escrow?

Retention must be placed in an interest-bearing account and accounted for separately. The interest goes to the contractor and subs, paid after completion and acceptance.

When must retention be released in Utah?

Within 45 days after the contractor's billing statement, measured from the latest of the triggering events in the statute, such as a certificate of occupancy or final acceptance. Subs get their share within 10 days after the contractor receives it.

How long does a Utah state agency have to pay?

The date set by contract, or within 60 days after receiving the invoice if the contract sets none. Late payments accrue interest at 2 percent above the IRS refund claim rate.

Is there a penalty for wrongfully holding retention in Utah?

Yes. Knowingly and wrongfully withholding retention triggers a charge of 2 percent per month on the amount improperly withheld, and the prevailing party recovers attorney fees and costs.
