What are all the taxes we are subject to in this country (USA) and the
state of Illinois?

Even an approximent answer involes far more research than $2 worth.
Many of us pay income tax, some federal, state and city, nearly all of
us pay sales tax, several kinds of telephone and utility tax, plus
manufacturers, wholesalers and retailers increase the price of goods
they sell by approximently the amount of tax, they and their supplies
pay.    Neil
