Assuming you made exactly 100k as a nice lowball you'd have owed $6947.92 in 2011 California income taxes. Harder to quickly find 2011 Austin property taxes but using todays rates without the homestead exemption you would have paid $4653 presuming you lived in Austin proper with Austin ISD taxes.

This is obvious a simplified calculation assuming basic W2 income and may very well not have applied to you, but for others reading it's nice to see some actual numbers.
