Questions, answered.
Are the 2024 Medicare amounts official?
Yes. CMS published the amounts; the sources below identify the announcement.
Which income counts for IRMAA?
Modified adjusted gross income is ordinarily adjusted gross income plus tax-exempt interest from two tax years earlier. Certain changes can justify a new determination from SSA.
Will a married couple pay one premium?
Medicare costs are generally per enrolled person. Joint filing uses the joint income thresholds, but each spouse can owe a premium and surcharge.
Does the Part D base amount equal my plan premium?
No. It is a national benchmark. Your chosen plan premium and any Part D income-related surcharge are separate.
Can retirement reduce an IRMAA assessment?
Work stoppage or reduction can be a qualifying life-changing event. Follow SSA-44 and SSA’s evidence rules; a lower entered calculator income does not itself change the assessment.
