Given that WA state doesn't have income tax. I am assuming it must be quite difficult to introduce city income tax. What exactly are the issues here?

The state supreme court in the 1930s heard a court case on a then newly enacted income tax and said it was unconstitutional. So it's still presumed to be the same. Seattle has created a kind of test income tax separately that they are trying to use to overturn that court case.
