To extend the break-in-service consideration for firefighter retirements, and other purposes.

H.R. 4672 would broaden and extend how service as a firefighter is credited for federal retirement purposes. It expands the definition of who qualifies as a firefighter to include not only frontline nonwildland and wildland firefighters, but also certain workers who move into supervisory or administrative roles after at least three years of frontline duties and who have limited or no breaks in service. It also creates a pathway to credit service performed before the bill’s enactment (dating back to October 1, 2003) for retirement purposes if that service would have counted as firefighter service under the amended definition and if a break in service had previously prevented it from counting. To receive retroactive credit, individuals must elect with their employing agency and repay the approximate amount that would have been contributed during the prior service, plus interest; the government would also contribute the corresponding employer portion. The bill directs the Office of Personnel Management (OPM) to inform and assist eligible individuals. In short, the bill is designed to recognize and credit more firefighter-related service for retirement, including some periods of break in service and pre-existing service, with a process for retroactive contributions and adjustments to retirement benefits.
