High-income taxpayers pay an additional charge for Medicare Parts B and D. The Part B surcharges for 2014 are unchanged from 2013; those for Part D are only slightly higher for 2014 than in 2013. “High income” means having modified adjusted gross income over $85,000 if single (or married filing separately), or $170,000 if married filing jointly.
