Around one third of Americans expect Social Security will be a major source of their retirement income, according to a 2017 Gallup poll. If you're going to be reliant on Social Security to fund your lifestyle as a retiree, it's important you understand exactly how much money you'll have available to you.

This means not only figuring out what your benefit will be worth depending upon your age at retirement, but also determining if you'll lose a portion of your Social Security benefits to income taxes.

In fact, there are a total of 37 states where you can enjoy your Social Security benefits without paying state taxes on this important source of income.
