How much does Part B coverage cost?

Most people will pay the standard premium amount, which was $104.90 in 2013.

Some people may pay a higher Part B premium If your modified adjusted gross income as reported on your IRS tax
return from 2 years ago (the most recent tax return information provided to Social Security by the IRS) is above a certain amount, you may pay more. This doesn’t affect everyone, so most people won’t have to pay a higher amount.

Your modified adjusted gross income is your adjusted gross income plus your tax exempt interest income. Each year, Social Security will notify you if you have to pay more than the standard premium. The amount you pay can change each year depending on your income.

If you have to pay a higher amount for your Part B premium and you disagree (for example, if your income goes
down), call Social Security at 1-800-772-1213. TTY users should call 1-800-325-0778.

If you get benefits from RRB, you should also contact Social Security. RRB doesn’t make income determinations.
