FIRST YEAR OF SOCIAL SECURITY

People get really confused when they start getting SS.   If you are not full retirement age, SS can reduce your benefits if you earn over a certain amount.  But they do not do that during the FIRST year that you transition from working to getting SS.  After that, if you are not full retirement age, they can reduce your benefit if you continue to work and earn over the limit.

None of that means that your SS is not taxable during the first year.   It is.   If you receive other income while receiving SS, your SS can be taxable.   If you were expecting SS to be "tax free" the first year, you were mistaken about how it works.
