If your income has gone down due to any of these circumstances and the change will make a difference in the income level Social Security considers, contact Social Security as soon as possible to explain that you have new information and want a new decision about your Income-Related Part B premium. You will need to show evidence of the event and provide proof or an estimate of your reduced income. Evidence of the event could be an original or certified copy of a marriage certificate, death certificate or divorce decree.  Proof of the change in your income in 2006 could be a copy of your return for tax year 2006 or an estimate if you have not yet filed your 2006 taxes. If your income will not change until 2007, you can give Social Security an estimate of what you think your income will be.

To report the change, you can use Form SSA-44, Medicare Part B Income-Related Premium - Life-Changing Event.
