When payment of compensation has been unreasonably delayed or refused
What This Rule Does
A late check can lead to an added penalty. The delay must be unreasonable, not just a normal processing issue.
A missing benefit check can throw rent, gas, food, and medical visits into stress. California workers comp has a penalty rule for that problem. It does not punish every slow payment. It asks a focused question: was the payment due, and was the delay or refusal unreasonable?
The rule can apply before or after a formal award. It can involve temporary disability, permanent disability, medical mileage, settlement money, or another comp benefit.
How the Penalty Is Measured
The WCAB can add up to 25 percent of the delayed payment. The added amount is capped at $10,000.
The penalty is tied to the payment that was late or refused. It is not based on the full value of the whole case unless that whole payment was delayed. The judge looks for a fair result.
If a weekly disability check was late, the penalty issue starts with that unpaid check. If settlement money was late after approval, the issue may focus on the amount due under the order.
| Issue | Plain meaning |
|---|---|
| Covered conduct | Unreasonable delay or refusal to pay workers comp benefits. |
| Main increase | Up to 25 percent of the delayed or refused payment. |
| Dollar cap | Up to $10,000 for the penalty tied to that delay. |
| Self-correction | The employer may pay a 10 percent self-imposed penalty within 90 days after discovering the issue. |
| Time limit | A penalty action must be brought within two years from the date the payment was due. |
The 10 Percent Self-Correction Rule
If the employer finds the problem first, it may correct the delay and add a 10 percent payment.
Section 5814 gives the employer a way to fix some problems before the worker files for a penalty. If the employer discovers the possible violation first, it may pay the delayed benefit plus a 10 percent self-imposed penalty. That must happen within 90 days after discovery.
This can still leave questions. Was the payment complete? Was the added 10 percent tied to the right benefit? Save the check stub, printout, and correction letter.
Credit for Late-Payment Increases
A section 4650 late-payment increase can reduce the added award for the same delayed benefit.
California has another rule for late temporary or permanent disability payments. That rule can add 10 percent when certain disability payments are late. If that increase was already paid on the same delayed benefit, it is credited against the penalty under this statute.
This avoids stacking two full penalties on the same late check. It means the judge must count what has already been paid.
Settlement and Trial Waiver Risk
Old penalty claims can be treated as resolved by a settlement, award, or trial unless they are clearly saved.
This is a trap for injured workers. When the WCAB approves a C&R settlement, a findings and award, or stipulations with orders, accrued penalty claims are treated as resolved unless the order clearly excludes them. The same problem can happen at trial if the penalty issue is not listed or saved.
Before signing or submitting issues, look for late checks or unpaid benefits. If a penalty claim should stay alive, it needs clear language.

Good records show when money was due, when it arrived, and what reason the claims administrator gave.
Build a simple timeline. Write down each benefit type, the date it was due, the date it was paid, and the amount received. Keep benefit notices, bank records, check envelopes, settlement papers, judge orders, mileage requests, pharmacy receipts, and messages from the adjuster.
Medical billing has its own limit. A delay in paying a doctor bill is not treated as an unreasonable treatment delay when treatment was authorized on time and the only dispute is the provider's bill.
A penalty request does not create a separate civil lawsuit. It is handled inside the workers comp case at the WCAB. The usual deadline is two years from the date the payment was due.

Frequently Asked Questions
Does every late workers comp check create a penalty?
No. The delay or refusal must be unreasonable. A judge looks at the benefit owed, the reason for delay, the length of delay, and the claim record.
How much can the added amount be?
The increase can be up to 25 percent of the delayed or refused payment. The added amount is capped at $10,000 for that penalty issue.
What benefits can be involved?
The rule can involve compensation payments such as temporary disability, permanent disability, settlement money, medical mileage, or other benefits owed in the comp case.
What if the adjuster pays a 10 percent increase first?
If the employer discovers the issue first and pays the delayed benefit plus a 10 percent self-imposed penalty within 90 days, that can replace the larger penalty claim for that payment.
Can I still raise late checks after settlement?
Maybe not. Accrued penalty claims are usually treated as resolved when the WCAB approves a settlement or award, unless the order clearly excludes the penalty issue.
What is the deadline to seek the penalty?
The action must be brought within two years from the date the compensation payment was due. Waiting can make an otherwise valid issue harder to raise.
Does a delayed doctor bill count?
Not always. If treatment was authorized on time and the only dispute is the provider's billing, the statute says that is not an unreasonable delay in treatment.
What should I bring to a lawyer review?
Bring payment notices, check stubs, bank records, WCAB orders, settlement papers, adjuster letters, mileage requests, and a due-date timeline.
