I live in Kansas, but my employer's office is in Kansas City, MO. I do work in the office. However, there are days I work remotely from home (in Kansas). My employer withholds MO tax and the 1% KCMO earnings tax. I know I can get a refund from KCMO for the days I work remotely. Are my wages for those days taxable in KS or MO?
Both. You will file as a resident for Kansas and a non-resident for Missouri. Kansas will give you a credit for the tax you pay to Missouri, but only up to the amount of Kansas tax on the same income. So if you earned $50,000, and Missouri taxes you $2,000 but Kansas only taxes you $1,800, you will get a credit of $1,800 credit on your Kansas return for tax paid to another state
In the Personal Info Tab, make sure you answer “yes” to the question if you worked in another state besides Kansas and select Missouri. Fill out your non-resident Missouri return first, and then complete your Kansas resident return. TurboTax will transfer all of the necessary information to your Kansas return to calculate and apply the credit.
I understand I need to file for both states, and know how to do so. What I'm not sure of is the MO form asks what part of your income was earned in MO. So if I worked at home, in KS, 1 day a week, and in the office in MO 4 days a week, are the earnings for the 1 day at home still considered as earned in MO?
