Excessive CA state taxes?

[goodglarp]

Last year I paid less than $300 to CA for my annual return. This year it is nearly $2000! Aside from the sale of some stock and a small income increase, last year's and this year's returns should be close. What should I be looking for that would explain the exorbitant increase?

Is it worthwhile to clear everything and start over?

I guess there's no recourse but to start over. Any suggestions on what to watch out for that may be causing this excessive state tax?

Check the state withholding in W2 box 17.  Compare your CA return line by line to last year.
