If you are clearing a public road you won’t be able to “collect taxes” from people. You could ask them for money but you can require it and I doubt you wouldn’t have any legal standing to force them to pay.

Also be aware that you could be held liable for any damage that is done by you or the your blown snow.

Additionally if you end up covering over people’s sidewalks or driveways while blowing you will be pissing them off.
