Ok, I've looked at At&T's 10-k's to see what income tax they've paid, going back to 2005. In no year did they even pay 10%, let alone the 35% that always gets touted as the corporate income tax rate. The biggest actual tax rate they paid was in 2008, when they paid just over $7B taxes on just over $124B operating revenue, for a whopping 5.6% tax rate. I would be surprised to find very many large corporations with significantly higher actual tax rates, but feel free to share some examples.
