One more reason--among many--why I'm not a lawyer

How is this constitutional? From "The Californai tax that terrifies tech":

Entrepreneurs and investors in California can expect to receive a rude shock in the mail if they sold their company in the last four years. Not only did the state's Franchise Tax Board (FTB) eliminate a tax break on capital gains for small business owners and investors, it announced the tax would be reinstated retroactively. This means those who benefitted from the break can expect a bill for unpaid taxes, plus interest, stretching all the way back to 2008.

I'm sure Texas will welcome the tech companies with open arms. It doesn't have the ocean or the vistas but, having lived there, I can confirm it's a great place to be. (And to be fair, the beaches in Galveston are nice, though not comparable of course.)

Interesting. I see California has found a way to stop citizens from taking measure to avoid taxes. They give a tax break then retroactively revoke it with interest. It's not like you can move to avoid those shadow taxes you incurred years ago.
