Social Security Benefits: Your Questions about Social Security Credits
Q: Social Security tells me that I dont have enough credits to qualify for benefits. How do these credits work, and how is it possible for me to not have enough when I have worked for years and paid taxes the whole time?
A: When you work and pay Social Security taxes, you earn credits that are used to qualify you for social security benefits. The Social Security service bases the number of credits a person receives on the amount of money they earn and the amount of time they have worked. The necessary income level for receiving social security benefits credits rises a bit each year; as of 2008, you receive one credit for every $1,050 you earn. You can receive a maximum of four credits annually (which is why credits are also called quarters), and any credits you earn will remain on your record even during periods in which youre not working.
A certain number of credits or quarters are required in order to qualify you to receive social security benefits. This number is based on age, and is generally calculated by number of years worked. Most people looking to qualify for retirement social security benefits (that is, over the age of 62) will need 40 credits, or 10 years of work, to be eligible for benefits.
However, it can happen that a person who has worked a seemingly appropriate number of years does not gain the necessary credits for social security benefits. This occurs to workers who, during their working careers, did not (or do not) have social security taxes taken out of their wages. This situation mostly occurs among Federal employees hired before 1984, railroad employees with ten years or more of service, and state and local government employees whose employers do not participate in social security.
