Overview: Before any benefit can be paid, the SSA must establish that the worker has "insured status" — a threshold determined by work credits earned over a lifetime or recent period.

Work Credits Explained

Workers accumulate credits (also called quarters of coverage) by earning wages in covered employment. In 2026, one credit is earned for every $1,890 in covered earnings, and the maximum is four credits per year. That means earning roughly $7,560 in covered employment in 2026 earns all four credits for the year, regardless of when during the year that income is earned.

Because credits are earned at a fixed dollar threshold per credit (not per calendar quarter), a worker who earns $7,560 in January already has four credits for the entire year — the word "quarter" is historical and no longer corresponds to actual calendar quarters.

Fully Insured Status

Fully insured status is required for most Social Security benefits: retirement, Medicare eligibility, most survivor benefits, and (in combination with other requirements) disability benefits.

The general rule for retirement is straightforward: 40 credits (10 years of covered work) makes a worker permanently fully insured. Once earned, those 40 credits can never be lost, even after years of not working.

For workers who become disabled or die before accumulating 40 credits, the SSA uses a sliding scale: the worker needs one credit for each calendar year after turning 21, up to and including the year of disability onset or death (but capped at 40 credits and with a minimum of 6 credits). A 28-year-old who dies has only 7 years between age 21 and age 28, so their family needs to show 7 credits (though the absolute floor is 6). This provision means younger workers' families can qualify even without a full 10-year work history.

Currently Insured Status

Currently insured status is a more limited designation — it protects survivors of workers who have recent but insufficient work history to be fully insured. To be currently insured, the worker must have earned at least 6 credits in the 13-quarter period (roughly 3 years) ending in the quarter of death, disability onset, or retirement entitlement.

Currently insured status does not entitle the worker's survivors to the full range of benefits. It qualifies only:

Monthly benefits for a surviving spouse of any age who is caring for the deceased's child under age 16 or disabled
Monthly benefits for dependent, unmarried children under 18 (or 19 if in high school full-time)
The one-time Lump-Sum Death Payment of $255

It does not qualify the worker for their own retirement or disability benefits, nor does it qualify an aged widow or widower for survivor benefits.

FAQ

Can a worker be currently insured but not fully insured?
Absolutely. A young worker who has 6 credits in the past 3 years but fewer than 40 lifetime credits is currently insured only. If they die, their minor children and a caregiving spouse can receive benefits — but a widowed spouse would not qualify for aged survivor benefits until they reach 60.

If I stop working for 10 years, do I lose my insured status?
If you already have 40 credits, no — fully insured status is permanent. If you have fewer than 40 credits, you cannot earn more credits during the break, but you don't lose what you already have. Currently insured status, however, requires recent work and will lapse if you don't continue working.
