Some side business work/income in another state than where work and live

[shareintl]

How would doing a little side business (e.g. Uber driving) in another state from my work & home impact my taxes?   This would be added in just as part of my current little side business (doing help services) that I reported last 3 years but until now has been done ONLY in Wisconsin. 

So like on an extended visit or leave from WI, if I was to do some Uber self business in MO, would another change or complicate my taxes?

You working in another state would not complicate your taxes but you would be required to file a Missouri state return to reflect income earned in that state.  Assuming you will also work in Wisconsin, you would be required to file a Wisconsin state return as well.
