Are social security taxes taken out of a persons check when they reach age 65?

As long as a person works, they continue to pay "wage taxes", even if decide to start collecting SS while they are working.

This is neither silly or unfair, since, as each year they continue to pay into the system, the higher their benefit goes up, so that they may see an increase in their SS beyond any cost of living increase.

I am assuming by a person's "check", you meant a paycheck. If she just receives a SS check, no, the only taxes taken out is the Federal Income Tax, if she requests it.
