These organisms are classified as a kingdom, Fungi, which is separate from the other eukaryotic life kingdoms of plants and animals. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls.
If you will reach full retirement age in 2015, you may earn up to $3,490 per month without losing any of your benefits. But for every $3 you earn over that amount in any month, you will lose $1 in Social Security benefits.
To earn the maximum benefit, you must have made at least the maximum taxable amount of wages every year of your working life since the age of 21. In 2012, that amount was set at $110,100. If you earn any wages over and above that amount, you did not pay Social Security taxes on the earnings. Making an Adjustment If you're curious about your entitlement to retirement benefits, you can request a Benefit Statement by going online at ssa.gov or calling the agency as 800-772-1213.
