If you are self--employed, you earn Social Security credits the same way employees do (one credit for each $700 in net earnings, but no more than four credits per year). However, special rules apply if you have net annual earnings of less than $400. For more information, call Social Security to ask for a free copy of the factsheet, If You're Self--Employed (Publication No. 05--10022).

If you are in the military, you earn Social Security credits the same way civilian employees do. You also may receive additional earnings credits under certain conditions. For more information, call Social Security to ask for a free copy of the factsheet, Military Service And Social Security (Publication No. 05-10017).

Work Not Covered By Social Security

The following workers are not covered by Social Security:

How Many Credits Do You Need?

The number of credits you need to be eligible for Social Security benefits depends on your age and the type of benefit.

Retirement Benefits
Everybody born in 1929 or later needs 40 credits to be eligible for retirement benefits. People born before 1929 need fewer credits.

See the table below.

If you work for a nonprofit organization that was mandatorily covered by Social Security starting in 1984, a special provision applies that may allow you to receive retirement benefits with fewer credits. For more information, call Social Security to ask for a free copy of the factsheet, If You Work For A Nonprofit Organization (Publication No. 05-10027).

Disability Benefits
The number of credits required for disability benefits depends on your age when you become disabled.

If you become disabled before age 24, you generally need six credits during the three--year period ending when your disability begins.

If you are 24 through 30, you generally need credits for half of the period between age 21 and the time you become disabled.

If you are disabled at age 31 or older, you need the number of credits shown in the following table. Also, you must have earned at least 20 of the credits in the 10 years immediately before you became disabled.

Survivors Benefits
The family of a deceased worker may be able to get survivors benefits, even though the deceased worker had fewer credits than are otherwise needed for retirement benefits.

If you were born in 1929 or before, one credit is needed for each year after 1950, up to the year of death, in order for your family members to collect survivors benefits.

If you were born in 1930 or later, one credit is needed for each year after age 21, up to the year of death.

Regardless of when you were born, your dependent children could get survivors benefits if you had six credits in the three years before your death. Their benefits could continue until they reach age 18 (or age 19 if they are attending an elementary or secondary school full time).

Your widow or widower who is caring for your children who are under age 16 or disabled also may be able to get benefits.

Medicare
The Social Security credits you earn also count toward eligibility for Medicare when you reach age 65. You may be eligible for Medicare at an earlier age if you are entitled to disability benefits for 24 months or more. Your dependents or survivors also may be eligible for Medicare at age 65 or if they are disabled.

People who need kidney dialysis or a kidney transplant for permanent kidney failure may be eligible for Medicare at any age.
