What area are you going to be working in?
If you work in kansas city or live in "kansas city", you will have to pay an additional K.C. 1% Earnings tax per year to the city of KC.
If you live in Liberty and gladstone area, work in NORTH kansas city, you will not have to pay local KC 1% e tax.
If you work in MO and live in KS, you will have to pay taxes to both states, and vise versa..
I have worked in MO for almost 9 years, and lived in KS all my life..30 years so far...
The cost of living in MO is less than KS.. MO has lower gas prices,property taxes, you can buy a larger home in MO for the same price as a smaller home in KS...
Johnson county and Wyandotte county have the HIGHEST taxes in kansas, when you get car insurance and live in WY county, get ready to bend straight from the hips and take out a small loan... WY is a large county, but has a high crime rate raising your premium for home and car insurance.
As for your car inspection, you will have 30 days to get your car looked at and inspected if you live in MO. I have a phone number if you need one
Nothing needed if you live in kansas, as long as your car is already titled in KS...
