10% tax on profits or income?
[link|http://money.cnn.com/2006/01/30/news/companies/exxon_earns/|CNN]:
For the year the company earned net income of $36.1 billion, or $33.9 billion excluding special items. That's up 31 percent from the $25.9 billion it earned on that basis year earlier.
[...]
While oil and gasoline prices in the fourth quarter were down from the levels seen in September, that barely dented Exxon Mobil's top line. Revenue for the quarter was $99.7 billion, up from $81.9 billion in the year-earlier quarter, and down only 1 percent from the $100.7 billion in revenue in the third quarter. Full-year revenue came to $371 billion, or just over $1 billion a day.
There's an appeal to simplicity in taxing a business's income (it's easier to quantify) than profits, but some businesses have to spend a lot to make a little (e.g. grocery stores, IIRC).
I think business profits (or income) should probably be taxed, if only to keep them from accumulating huge bank accounts that can be used to distort competition (see: Microsoft). But I don't know of a way to do it simply that doesn't punish firms that must sell a lot to clear a little. If it's a tax on profits, then profits must be very carefully and clearly defined. E.g. How does depreciation, investment credits, leases, losses, long-term contracts, etc., etc., get handled?
Cheers,

(Who agrees with Box that 10% probably isn't enough, and who should read up on [link|http://en.wikipedia.org/wiki/VAT|VAT] - maybe that's the most transparent way to tax businesses.)
