I obviously don't have exact numbers, but I would argue it's quite a bit. Besides sales taxes and property taxes, they pay excise taxes to both states and the federal government. They may or may not pay federal income taxes, but the people they work for do. And Americans benefit from lower prices for food and other necessities.

Don't buy into that claim that their children receive a "free" education. They pay school taxes through their sales and property taxes, the same as everyone else.

But seriously, I promised myself I wouldn't go into one of my free market anarchist rants, so I won't.
