This subpart is related to several others. In subpart B of this part, we describe how you become insured for social security benefits as a result of your work in covered employment. In subpart D, we discuss the different kinds of social security benefits available—old-age and disability benefits for you and benefits for your dependents and survivors—the amount of the benefits, and the requirements you and your family must meet to qualify for them; your work status, your age, the size of your family, and other factors may affect the amount of the benefits for you and your family. Rules relating to deductions, reductions, and nonpayment of benefits we describe in subpart E. In subpart F of this part, we describe what we do when a recalculation or recomputation of your primary insurance amount (as described in this subpart) results in our finding that you and your family have been overpaid or underpaid. In subparts G and H of this part, we tell how to apply for benefits and what evidence is needed to establish entitlement to them. In subpart J of this part, we describe how benefits are paid. Then in subparts I, K, N, and O of this part, we discuss your earnings that are taxable and creditable for social security purposes (and how we keep records of them), and deemed military wage credits which may be used in finding your primary insurance amount.
