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.

California taxes were affected by CA deduction, CA personal exemption, and 401k (which I didn't max out, and even without it I think the original claim still stands although just barely)
