So you guys handle all states and all localities (and the corresponding tax table updates, etc?)

For instance, I have an employee in Florida so I have a UCT-6 for SUI, and also a couple employees in PA (so local taxes galore)

How do you handle a state such as California where the employee has to OPT OUT of receiving a paper paystub?

Don't take this as me bashing what you guys are doing, I'm just genuinely interested as this is a little bit of a hobby of mine (payroll consulting)

EDIT: I just read that they only support California at the moment. Bummer.
