That means you paid into the SSA system based on the social security earnings which is BEFORE the 401K is deducted.
Pre-tax health care is the item that reduced your earnings for SSA purposes.
Read the worksheet to see if the income added to half the SS is before or after I think it will be on box 10 so after the 401K is deducted saving you taxes on the SS income.
I think people are thinking of this as a tax withheld issue not a tax on benefits since most retired people don't have jobs with 401K.
401k has nothing to do with social security, it does not reduce those benefits
No - you pay in the same amount to ss, whether you contribute to a 401k or not.
very little compared to how much it will increase your retirement benefits coming from your IRA/401k plan
No.
