Yes that’s absolutely true, they do take advantage of international tax rules, but the insinuation that they pay almost no or very low overall corporate taxes is not true. I doubt the OP I was replying to expected the answer to be 24.6% of corporate income. I’ve got no objection to claims that’s too low, it’s a legitimate question, but let’s at least discuss this from an informed position.

Is that with or without payroll tax?

It doesn’t include payroll taxes, import duties or VAT / sales taxes.

Without.
