To be fair and rational (unlike many a chest thumping crowd), their salaries go under the tax hammer before being deposited to their favourite account. As such, saying that they pay zero tax is essentially false and misleading - the epitomization of illiterate journalism and gullible masses. The issue then is the income they make on their other ventures. I have no information on the holdings, estates and previous backgrounds of the other three, but Shahbaz pays quite a lot indirectly through the companies that he and his brother/family own. The mills and all pay corporate tax.
