Workers’ comp deadline calculator
Every California comp file runs on a handful of statutory clocks. Enter the date of injury — and the claim-form date if you have it — and the reference dates compute instantly. These are starting points, not legal conclusions: filings, benefit payments, and tolling can move every one of them.
Enter the claim-form date to compute — the clock runs from filing the DWC-1, not from the injury.
The presumption can be rebutted with evidence not reasonably discoverable in the window.
One year from the date of injury is the earliest the statute of limitations can run for filing an Application. Benefits paid move it: the year also counts from the last indemnity payment or last medical furnished — whichever is later.
If any benefit was paid, this date is NOT the bar date. Whether a claim is time-barred is an attorney question.
The window to claim new and further disability from the same injury. Petitions to reopen for good cause (§5803) run on the same five years from DOI.
The board must generally act within this window; filing before it closes preserves jurisdiction.
For 2008+ injuries, temporary disability is capped at 104 weeks of payments within five years of the date of injury (240 weeks for enumerated serious conditions). After this date, no further TD regardless of weeks used.
The calculator’s TD card runs the 104-week count on actual payment periods — this is only the outer wall.
Reference dates only, computed from the inputs above with no knowledge of your case. Statutes of limitations have alternative triggers, exceptions, and tolling doctrines this page does not evaluate — confirm every deadline with counsel before relying on it. The case phases behind these clocks are walked through in the timeline guide. Not legal advice.
