The income-related monthly adjustment amount is effective from January 1 through December 31 each calendar year. The Social Security Administration will refigure your Medicare Part B premium amount again next year when the Internal Revenue Service updates the information. Most people will pay the standard premium amount. However, if your modified adjusted gross income as reported on your IRS tax return from 2 years ago is above a certain amount, you may pay an Income Related Monthly Adjustment Amount (IRMAA). IRMAA is an extra charge added to your premium. This will apply to Part B and you Monthly Part D Premiums.
If your income is above $85,000 (single) or $170,000 (married couple), then your Medicare Part B premium may be higher than $121.80 per month.
Social Security will use the income reported two years ago on your IRS income tax return to determine your premium (if unavailable, SSA will use income from three years ago). For example, the income reported on your 2014 tax return will be used to determine your monthly Part B premium in 2016. If your income has decreased since 2014, you can ask that the income from a more recent tax year be used to determine your premium, but you must meet certain criteria.
