§ 418.1120. How do we determine your income-related monthly adjustment amount?

(a) We will determine your income-related monthly adjustment amount using your tax filing status and modified adjusted gross income.

(b) Tables of applicable percentage. The tables in paragraphs (b)(1) through (b)(3) of this section contain the modified adjusted gross income ranges for 2007 in the column on the left in each table. The middle column in each table shows the percentage of the unsubsidized Medicare Part B premium that will be paid by individuals with modified adjusted gross income that falls within each of the ranges. The column on the right in each table shows the percentage of the Medicare Part B premium that will be subsidized by contributions from the Federal Government. Based on your tax filing status for the tax year we use to make a determination about your income-related monthly adjustment amount, we will determine which table is applicable to you. We will use your modified adjusted gross income to determine which income-related monthly adjustment amount to apply to you. The dollar amount of income-related monthly adjustment for each range will be set annually as described in paragraph (c) of this section. The modified adjusted gross income ranges will be adjusted annually as described in § 418.1115(e).

(1) General table of applicable percentages. If your filing status for your Federal income taxes for the tax year we use is single; head of household; qualifying widow(er) with dependent child; or married filing separately and you lived apart from your spouse for the entire tax year, we will use the general table of applicable percentages. When your modified adjusted gross income for the year we use is in the range listed in the left column in the following table, then the Federal Government's Part B premium subsidy of 75 percent is reduced to the percentage listed in the right column. You will pay an amount based on the percentage listed in the center column.

(2) Table of applicable percentages for joint returns. If your Federal tax filing status is married filing jointly for the tax year we use and your modified adjusted gross income for that tax year is in the range listed in the left column in the following table, then the Federal Government's Part B premium subsidy of 75 percent is reduced to the percentage listed in the right column. You will pay an amount based on the percentage listed in the center column.

If your Federal tax filing status for the tax year we use is married filing separately and you lived with your spouse at some time during that tax year, and your modified adjusted gross income is in the range listed in the left column in the following table, then the Federal Government's Part B premium subsidy of 75 percent is reduced to the percentage listed in the right column.
