Apparently, if you are participating in CalSTRS as a FT teacher, this causes the deductible amount of your IRA to phase out as if your contributing to a ER sponsered plan like a 401k. Seems illogical when just contributing to Social Security does not have the same effect.

However, I cannot find it in writing at either IRS or CalSTRS websites/materials. Does anyone have a clue as to where it may be spelled out?
