If California was your state of residence when you entered the service, their rule is that you became a non-resident for tax purposes when you left California under PCS orders.
That means you only have to file a CA return if you had CA-source income during 2016. For example, if you rented out your CA home, the rental income would be CA-source income and you'd have to file a CA non-resident return.
But if you had no CA-source income in 2016, you do not have to file a CA tax return.
