You can get Social Security retirement benefits as early as age 62, but if you retire before your full retirement age, your benefits will be permanently reduced, based on your age. For example, if you retire at age 62, your benefit would be about 25 percent lower than what it would be if you waited until you reach full retirement age. Some people stop working before age 62. But if they do, the years with no earnings will probably mean a lower Social Security benefit when they retire. See this web page from the Department of Social Security for more information. As far as taxes see this web site.
