No. Each year Social Security requests your most recent tax return information from the Internal Revenue Service (IRS). To determine the 2007 Part B premium, IRS generally provides information for tax year 2005. For 2008, IRS will generally provide information for tax year 2006. Social Security uses your modified adjusted gross income (MAGI) to determine your premium for one year. Your MAGI is a combination of your adjusted gross income and tax exempt interest income.

Your tax return for 2006 will reflect only your income for that year. So, if your premium increased in 2007 due to a one-time increase in your income in 2005, such as sale of property, it could decrease in 2008. Your 2008 Part B premium depends on your income for tax year 2006.
