Yes, Google has to pay an army of both lawyers and accountants to take care of all the crazy complex tax scheme internationally. I know several people who run startups with such schemes and they give 1% of their revenue to their accountant. If we got rid of the IRS and equivalent and just used a flat tax on the total amount of revenue, well, let's say the CPA industry would take a plunge and regular folks and companies like Google would save billions.
