Subtracting two values in SQL Case Statement

Question

I need to subtract two values I am calculating on the fly in a case statement but I cant seem to get it done. Here is what I am trying to do and the error I get is "Incorrect syntax near the keyword END':

[Date] = 
  CASE 
    WHEN [col] = 'YES' 
    THEN CONCAT(MONTH(AnniversaryDate),'/',DAY(AnniversaryDate),'/',(YEAR(GETDATE()) + (YEAR(GETDATE()) - YEAR(AnniversaryDate)))
    END,

Should I instead store the difference in some other column rather than calculate the subtraction where I am currently calculating it?

Thank you!
