Are earnings taxed after reaching full retirement age?

[Coleen3 · Accepted solution]

Yes. There is no age at which taxation stops. You have a higher standard deduction at age 65, however.

Yes.  You just don’t lose part of your SS benefit checks.  But all your income is still taxable and part of your Social Security might be taxable too.

Up to 85% of Social Security becomes taxable when all your other income plus 1/2 your social security, reaches:
Married Filing Jointly: $32,000
Single or head of household: $25,000
Married Filing Separately: 0

Social Security is on 1040 line 5a and the taxable amount on 5b.
To see the Social Security Benefits Calculation Worksheet  in Turbo Tax Online version you would have to save your return with all the worksheets to your computer.  Or if you are using the Desktop program you can switch to Forms Mode (click Forms in the upper right) and click on SS in the list on the left side.
