Currently we do not have information on what to expect in Kansas as unfortunately as no one here has worked or been contacted to work in Kansas. In this case, we will have to direct you to Wikipedia or the Chamber of Commerce site.
There is a state Income Tax. As with most states if you live in a state with no income tax and you are working on contract we suggest you follow the Contractor's Rule and make sure you return home at least once a month, do not setup an official residence. Most of all follow the State laws concerning residency.
