It is a tax paid on earned wages and business profits but not on Social Security or pensions. The average annual earnings tax paid in Kansas City is about $340, and the average business profits tax paid is about $2,050.
Nearly 50 percent of the tax is paid by people who don’t live in Kansas City but work within the city limits; about 20 percent comes from Kansas residents and 30 percent from residents of the Missouri-side suburbs. Those taxpayers do not get a vote, because taxes are generally decided on by residents of the city that imposes them.
I have a similar problem. My employer has "bricks and mortar" in every state and 30 countries. When I travel to another company location, I'm compelled to record the zip code on my time card. The consequence is that I have to file income tax in CA and sometimes NE in addition to my state of residence, ID. CA taxes me, but I have no voice as a voter since I'm an ID resident. Taxation without representation. Frankly, I pay more CA state income tax than many CA state residents.
This year I'm trying to avoid any more visits to San Diego than absolutely required. Instead of the original "one week per month", I've restrained it to one visit total in 2017 as of the current time. Thus far, no calls to Omaha. It only takes ONE visit to either spot to force a W2 and extra state filing.
