Check under the summary of your earnings for an item indicating Social Security wages. If there is no separate total for Social Security earnings, then the amount that goes into Box 3 is the same amount that is in Box 1.

The maximum taxable earnings for Social Security purposes varies from year to year. Check with the Social Security Administration for the maximum taxable earnings for the year of reporting. This information is available online at the Social Security Administration website.
