Social Security benefits are based upon your earnings as reported to the Social Security Administration (SSA). For this reason, it is important that you report these earnings to us promptly and accurately. (See §§1402-1404.)
Your earnings are used to find out whether you are entitled to retirement, survivors, disability, and health insurance benefits (see Chapter 2). Also, they are used to calculate cash benefit rates (see Chapter 7).
