You are allowed to continue working and still receive Social Security benefits. However, if you are under full retirement age, you are limited in the amount you can earn. In 2011, that amount is $14,160. If you are under full retirement age, then you will have to repay $1 for every $2 year earn over that limit.
The income limits vary from one state to another. You need not have worked under Social Security to qualify for SSI. Ask your local Social Security office about the income limits in your state and contact us for Supplemental Security Income (SSI) (Publication No. 05-11000). This booklet is also available in Braille and other formats.
