At what level of retirement income does social security tax a portion of your retirement when you are 78 years old?

[thedports]

is there an age or income level where they do not tax social securiry?

[DawnC0 · Accepted solution]

There are certain situations when seniors must include their Social Security benefits in gross income. If you are married but file a separate tax return and live with your spouse at any time during the year, then all of your Social Security benefits are considered gross income which may require you to file a tax return. 

In addition, a portion of your Social Security benefits are included in gross income, regardless of your filing status, in any year the sum of half your Social Security plus all other income, including tax-exempt interest, exceeds $25,000 or $32,000 if you are married filing jointly.
