(a) When payment of compensation has been unreasonably delayed or refused, either prior to or subsequent to the issuance of an award, the amount of the payment unreasonably delayed or refused shall be increased up to 25 percent or up to ten thousand dollars ($10,000), whichever is less. In any proceeding under this section, the appeals board shall use its discretion to accomplish a fair balance and substantial justice between the parties.
What does California Labor Code §5814 actually penalize?
Section 5814 imposes a 25% penalty on top of any workers' comp benefit the carrier withheld or delayed without good cause, awarded by the WCAB judge.
Section 5814 is the 25% unreasonable-delay penalty, imposed by the WCAB judge on top of any workers' compensation benefit the carrier withheld without good cause, applied to the specific delayed payment. When section 5814 and the automatic 10% self-imposed increase apply to the same payment, they stack. Certified Specialist Eman Yazdchi (California Board of Legal Specialization, State Bar of California) files section 5814 penalty petitions any time a carrier delays without good cause.
Under California Labor Code §5814, a California workers' compensation insurer or self-insured employer that unreasonably delays or denies a benefit faces a 25% penalty on the specific benefit unreasonably withheld. The penalty applies to the actual species at issue, temporary disability unpaid on time, permanent disability withheld, or treatment authorization unreasonably denied, not the entire award. The penalty is awarded by the WCAB judge on the record, in addition to the underlying benefit and the self-imposed increase under California Labor Code §4650, California's 10% automatic self-imposed increase on late TD or PD payments.
What counts as "unreasonable" delay under California §5814?
The unreasonable-delay standard turns on whether the carrier had a legitimate basis for the delay, a genuine compensability dispute can be reasonable; ignoring a doctor's report is not.
Under California Labor Code §5814, an unreasonable delay or denial is one without genuine factual or legal dispute. California case law has applied §5814 to: temporary disability checks issued late without explanation; treatment authorizations sitting past the §4610 UR timeframes; medical mileage reimbursements paid months late; permanent disability indemnity withheld after Stipulations with Request for Award; and Compromise & Release proceeds delayed beyond the statutory payment window. A genuine legal dispute, for example, a UR denial later overturned through IMR, is generally not unreasonable absent additional conduct.
How is the §5814 penalty calculated?
The 25% section 5814 penalty is calculated on the specific delayed benefit, not the entire award, one late TD payment generates a 25% penalty on that payment only.
Under California Labor Code §5814, the California 25% penalty is calculated on the specific species of benefit unreasonably delayed. If $10,000 in temporary disability was withheld for three months without justification, the §5814 penalty is $2,500. The penalty is separate from the California Labor Code §4650 10% self-imposed increase for late indemnity payments, separate from any back interest owed, and separate from any §132a remedies if the underlying delay was retaliatory.
How does §5814 interact with §4610 Utilization Review delays?
Section 5814 interacts with the section 4610 utilization-review delay rule: when a UR denial is reversed and treatment was unreasonably withheld, the section 5814 penalty can attach.
Under California Labor Code §4610, UR decisions on California medical treatment must be made within strict time limits, five working days for prospective review, 72 hours for expedited review, 30 days for retrospective review. An untimely UR decision is procedurally invalid and the requested treatment is deemed authorized. A pattern of untimely UR or boilerplate denials later overturned through IMR under California Labor Code §4610.5 can support a §5814 California penalty for unreasonable denial of treatment.
How long does a California worker have to file a §5814 penalty claim?
The section 5814 claim must be filed at the WCAB within the five-year reopening window under the related statute from the date of injury.
Under California Labor Code §5814 and California Labor Code §5410, a California injured worker generally has the five-year reopening window to claim a penalty for benefits unreasonably delayed during the pendency of the case. The penalty is asserted in a Petition for Penalty filed with the WCAB. Each instance of unreasonable delay can be the subject of its own §5814 penalty claim, and multiple penalty claims can be heard together at a single California hearing.
Per the DIR's 2025 statutory adjustment, the maximum supplemental job displacement benefit under California Labor Code §4658.7 remains at $6,000, a cap that has not been adjusted since the 2013 SB 863 reform, so its real value has eroded roughly 27% against the CPI.

What counts as 'unreasonable' under California §5814?
Under California Labor Code §5814, an unreasonable California delay or denial is one without genuine factual or legal dispute. Examples include temporary disability checks issued late without explanation, treatment authorizations sitting past the California Labor Code §4610 UR timeframes, medical mileage reimbursements paid months late, and Compromise & Release proceeds delayed past the statutory payment window. A genuine legal dispute, a UR denial later overturned through IMR, is generally not unreasonable absent a pattern of conduct or additional bad-faith indicators.
How is the California §5814 penalty actually calculated?

Multiple California penalty species can stack on the same claim.
Can a California §5814 penalty apply to Utilization Review denials?
Yes, under California Labor Code §5814, a pattern of untimely Utilization Review or boilerplate UR denials later overturned through Independent Medical Review under California Labor Code §4610.5 can support a California penalty for unreasonable denial of treatment benefits. A single legitimate UR dispute is generally not unreasonable, but a pattern of California UR denials reversed by IMR, combined with delay in re-authorizing the treatment after IMR, is strong evidence of §5814 unreasonableness before the WCAB judge.
