I should clarify my previous post on this. The increased AGI does not
impact The SS benefit. It impacts the Medicare Part B. Medicare Part
B DEDUCTION for the premium goes up based on income.
Example: "Your 2008 deduction for Medicare Part B premium is $238.40."
"This is $96.40 for the standard Medicare Premium
PLUS $142.00 for the income-related monthly adjustment
amount based on your 2006 income tax return"
This is in quotes as it comes from an actual letter notice from the SS
Admin dated 11-21-07. The individual this is happening to had a huge
gambling win in 2006 and an AGI well over the 410,00 threshold for
married filling jointly. So the SS Admin increases his Medicare premium
deduction that is taken out of his his SS check. So, even though SS
goes up in 2008 by 2.3% -- his actual check will be less in 2008 due to
the increased premium deduction fo the Med Part B.
Sorry if I confused anyone about the topic.
