Labor Code §5814 Penalties: When Comp Payments Come Late

When a California workers’ comp benefit is unreasonably delayed or denied, §5814 adds up to 25% of the delayed amount (capped at $10,000), less any automatic 10% already paid under §4650(d). How the two penalties differ, with computed examples.

Comp benefits are supposed to arrive on a statutory clock. When they don’t, California has two very different penalties — one automatic, one litigated — and parties routinely confuse them. Here is the split, with the arithmetic computed.

§4650(d): the automatic 10%

If a TD or PD installment is paid late, the payer owes the installment plus 10% — self-executing, no fault required, no WCAB finding needed. It applies per late payment and is the everyday penalty (the statute exempts payments due before or within 14 days after the claim form was submitted, and wages continued under a salary-continuation plan). The calculator has a §4650(d) toggle that applies the 10% to the computed indemnity so demand letters and audits use the right number.

§5814: the litigated 25%

When payment of ANY class of benefit is unreasonably delayed or refused, the WCAB may increase the delayed amount by up to 25%, capped at $10,000 per violation — less any §4650(d) 10% already paid on the same payment (§5814(d)). Unreasonableness is the whole fight: the payer must show genuine doubt of liability based on a reasonable investigation. Classic triggers — the late first TD check, benefits cut off without notice, an award simply not paid.

The arithmetic

Delayed 15% PD award ($14,645) → 25% = $3,661.25
Delayed 36% PD award ($50,170) → 25% = $12,542.50 → capped at $10,000
Two missed $800 TD checks → 25% of $1,600 = $400

The base amounts come straight from the schedule — the same engine-computed awards on the money chart and in the body-part money pages; TD rates are in TD vs. PD. Note the asymmetry: on small delays the 25% is modest, which is why §5814 fights cluster around whole delayed awards, not single checks.

Practical notes

Penalty exposure attaches to the specific payment delayed (TD, PD, medical), multiple violations can stack separately, and a §5814 award also carries attorney-fee exposure under §5814.5 when an award was already in place. For payers: the paper trail of a real investigation is the defense. For applicants: the penalty petition rises or falls on the delay timeline — dates, amounts, notices. Both sides need the underlying indemnity computed exactly, which is what the calculator is for. Estimates for informational use; not legal advice.

FAQ

What is the penalty for late workers’ comp payments in California?

Two layers. §4650(d) adds an automatic 10% to a late-paid TD or PD installment — no fault needed. §5814 adds up to 25% of the delayed benefit (capped at $10,000 per violation, less any §4650(d) 10% already paid on it) when the delay or refusal was unreasonable — that one is litigated before the WCAB.

How much is a §5814 penalty worth?

Up to 25% of the amount delayed, with a $10,000 maximum. Delay an entire $14,645 PD award unreasonably and the exposure is $3,661.25; delay a $50,170 award and the 25% would be $12,542.50 — but the statute caps it at $10,000.

What counts as an unreasonable delay?

There is no fixed number of days — the employer must show genuine doubt of liability from a reasonable investigation. Late first TD checks, stopped benefits without notice, and ignored awards are classic fact patterns; a documented, good-faith dispute usually is not. It is a fact question the WCAB decides.

Is the 10% increase automatic?

Yes — §4650(d) is self-executing: if a TD or PD installment is paid late, the payer owes it plus 10%, without any finding of unreasonableness. The calculator has a §4650(d) toggle that adds the 10% to the computed indemnity.
