ok thx. In 10 years I've never run into it. InterestingRead both because it can be on their own benefit. But it is only an issue for people that have a pension from employment were they did not contribute to social security a quick scan of the Medicare and social security earning numbers will quickly show if someone will be subject ie you see years of no to very little social security earnings and the corresponding Medicare column shows 50k in earnings its due to a position were they did not contribute to social security, you just need to know your state many state pensions the employee still contributes to social security, new federal employees are under FERS and they contribute to SA but older CSRS employees did not obviously since its been many years since a nonFERS employee has been hired its becoming less of an issue.
