En español | Yes. This is how it works: There are two different limits under the Retirement Earnings Test. The lower limit is $17,040 in 2018 and applies to everyone who is below the full retirement age (age 66) for all of the year. For these people, benefits are reduced by $1 for every $2 in earnings over $17,040. The upper limit, $45,360 in 2018, applies to anyone who reaches full retirement age in the year and is only applied during the months prior to that birthday's month. For these people, benefits are reduced by $1 for every $3 in earnings over $45,360.
