To qualify for Social Security, you must have worked five out of the last ten years. Work credits are awarded to you when you have a full-time, tax-paying job. These credits are based on how much you have earned. They will determine your eligibility for disability, retirement, and survivor's benefits. For 2018, you will receive one credit every time you are paid $1,320 by your tax-paying job.
