Retirement tax questions

Hi Criter-3 -- thanks for the reply.  Just wanted to double-check your answer that social security does apply toward the income calculation (with a limit of $4300; $358.33/month).  I would think the vast majority of the elderly population would be collecting social security.  And the average s.s. check is $1666.49/month ($20k/yr).  If this were true, it would seem almost no one could claim an elderly parent as a dependent.  Does this sound right?

 

Thanks,
-Marc
