Though some internet rumours claim that the government no longer taxes Social Security payments once you reach a certain age, such as 70.
this is simply not true. Social Security benefits are taxed from the time you begin receiving them until you die.
Some of the ambiguity surrounding the tax status of Social Security payments is most likely due to the fact that each state treats Social Security differently.
Many states treat Social Security in the same way that the federal government does, taxing every dollar based on the tax bracket you fall into with your total retirement income.
They may only tax half of it, or they may have some other formula for determining how much of your monthly pay is subject to state taxes.
Finally, some states do not levy any Social Security taxes. Some of these states have a special exemption, while others simply do not have a state income tax.
Yes, Social Security is taxed federally after the age of 70. If you get a Social Security check, it will always be part of your taxable income, regardless of your age.
