I got curious while reading and I've read this[1]:

> Revenue is total money from core business activities before expenses are deducted.

> Income, or net income, is earnings remaining after all expenses are deducted from revenue.

Sorry for being pedantic. I don't understand why English has such ambiguous terms for something that shouldn't be. Or am I even more confused now?

To directly answer your comment: I agree that companies should be taxed on revenue and not income. Citizens are taxed on revenue, so why aren't companies?! They're supposed to be treated as people.

Producers produce up to the point marginal benefit equals marginal cost. Tax on revenue inflates marginal cost and would create shortages etc.

Sorry, I mixed them up (I am not a native speaker of English, but would have probably mixed them up in French as well :)). Thanks (I updated my post)
