The article you quote starts with a lie. That's the only way I can describe it, because it's supposed to be an accounting publication and should therefore fucking know! Corporation tax is not levied on revenue it's levied on earnings.
Of course it isn't. Forget the hyperbole, if you want that kind of analysis you may as well argue they report that 2+2=4. Accountants know what the corporation tax rate is, they even know how it is calculated, they don't need a headline, or you, to explain it. The focus of that article is to compare the revenues and tax and ask if they are typical. If not, why not? You missed that because you skipped over the big words you didn't understand.
In other headlines:
3+3=6
8/2=4
10-9=1
