A. It will depend on the amount of your family income. About one-third of people who get Social Security have to pay income taxes on their benefits. You will have to pay federal taxes on your benefits if you file a tax return as an individual and your total income is more than $25,000. If you file a joint return with your spouse, you will have to pay taxes if your total income is more than $32,000.

As your family income goes up, so may the taxes on your Social Security benefits. At higher income levels, up to 85 percent of your Social Security benefits may be taxed.

Before you sign up for Social Security, you may wish to consult an accountant or other financial adviser to learn your options. You should also check to find out whether your state and local authorities tax benefits — many do not.
