Live in Kansas but work in Missouri - also work remotely from home

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?
