Definition
A state-run program, funded by taxes on employers, that pays weekly benefits to workers who lose a job through no fault of their own and are able to work and actively looking. Benefits replace a fraction of prior wages up to a weekly cap set by each state, for a limited number of weeks. Quitting voluntarily or being fired for misconduct usually disqualifies a claim, and benefits are taxable income.
Why it matters
Unemployment is the only income replacement most people have between jobs, and it is rarely enough on its own, which is what an emergency fund is for. Because nothing is withheld unless you ask, a season of benefits can produce a surprise tax bill the following spring.
