Anyone on Social Security (SS) in 2019 is "held harmless" from the 2019 amount if the increase in their SS monthly benefit does not cover the increase in their Part B premium from 2019 to 2020. This hold harmless provision is significant in years when SS does not increase but that is not the case for 2020. There are additional income-weighted surtaxes for those with incomes more than $85,000 per annum.
