If you mean the annual earnings limit, which is $14,160 in 2009, yes, that rule is in effect until full retirement age. That limit also applies to your family members whose benefits are based on your work record. Mercer Human Resource Consulting, in its 2007 Guide to Social Security and Medicare Overview, interprets the earnings limit in this way: "If you earn more than the exempt amount, your benefits and your family members' benefits that are based on your work record will be reduced."
