Come to find out, there are actually scenarios to where you will need to pay some taxes on your Social Security benefits. If you make a combined income of no more than $25K, or $32K/yr as a joint filer, you will not have to pay any taxes on SS benefits. But over that, you will.
Depending upon how much over, the tax is between 50-85% of your benefits received. Just something to keep in mind. If you are solely living on Social Security, likely you won't ever have to worry about this. But if you have other supplemental income, like another job after retirement or investments that continue to earn that count as income, you will need to keep this in mind. http://govthub.com/posts/68/paying-taxes-on-social-security-benefits.aspx
