If you work in a certain area then changed that’s how they get you. Honestly just pay the $10 where u live or worked. Honestly don’t think you can win they will fuck you and that $10 will be $3000 in 3 years. Always always pay the keystone collections I have been raised that way and own a business. I tell my employees when I get the notice just pay it or you will be fucked in the future. Yes it sucks

Edit: I read through most of these comments and they don’t know what they are talking about. Keystone collections does the municipal tax where your business is located and sometimes where you live. I advise just to pay it shouldn’t be to much. If your dealing with 1000s and they say u haven’t paid in x years fight it
