The clock
Kansas runs a comp claim on two clocks, not one
The first is notice to your employer — within 30 days, or 20 days if you no longer work there. That clock is measured in days, running from an accident you may still be having tests for, and it is the deadline that actually gets missed. The second is the claim itself, filed with the state: three years from the accident, or two years from the last payment. That is longer than the 2 years an ordinary KS injury lawsuit gets — but it is the notice clock above, not this one, that decides most claims. A workplace injury commonly takes 9 to 18 months to reach maximum medical improvement, which is when the permanent-impairment part of the claim can finally be rated. That sits comfortably inside the 36-month filing window, so the pressure here is on the notice deadline rather than this one. And if someone other than your employer contributed to it — a subcontractor, a defective machine, a driver — that separate liability claim runs on Kansas's general 2-year injury deadline instead. Two clocks on the same accident, and only one of them is the comp one.
