You’ll pay more for Part D if the income you reported on your IRS tax return two years ago was above $85,000 per year ($170,000 for couples). The income that counts is the adjusted gross income you reported plus other forms of tax-exempt income.

How much more you will pay depends on how high your income is. You will continue to pay your regular premium to your Part D plan. The additional premium will automatically be deducted from your Social Security check. If the additional premium is more than your Social Security check, Medicare will bill you.

The additional premium will be a percentage of the national base beneficiary premium which is $34.10 in 2016. The chart below will tell you how much more you will pay for Part D in 2016 if your income is above $85, 000 ($170,000 for couples).
