For 1978 and later, credits are based solely on the total yearly amount of earnings. The number of credible QQs is obtained by dividing the individual’s total earned income by the increment amount for the year. The maximum number of quarters per year is 4. All types of earnings follow this rule. The amount of earnings needed to earn a credit increases and is different for each year. The Credit of Qualifying Quarters Chart presented below outlines the amount of earnings needed for each credit for 1979 through 2012.

A current year quarter and a quarter earned in the immediately preceding year may be included in the 40-quarter computation even if SSA does not have information about those earnings on the automated system. The SSR should use the individual's earnings (earned to date) as the numerator to determine the number of quarters earned in a current year for which SSA does not yet have data on the automated system. IMA has elected to allow credit for a quarter even if the year is not yet complete.
