If you work for someone else, only your wages count toward Social Security’s earnings limits. If you’re self-employed, we count only your net earnings from self-employment. For the earnings limits, we don’t count income such as other government benefits, investment earnings, interest, pensions, annuities, and capital gains. We do count an employee’s contribution to a pension or retirement plan, however, if the contribution amount is included in the employee’s gross wages.
If you work for wages, income counts when it’s earned, not when it’s paid. If you have income that you earned in one year, but the payment was made in the following year, it shouldn’t be counted as earnings for the year you receive it. Some examples are accumulated sick or vacation pay and bonuses.
If you’re self-employed, income counts when you receive it — not when you earn it — unless it’s paid in a year after you become entitled to Social Security and earned before you became entitled.
