Do you pay any tax?
I would suspect most pay taxes, a better question might be along the lines of ;
Do you withhold any tax income due to the government?
Do you employ any tax avoidance measures so as to deny income to the government?
Do you employ any aggressive tax avoidance measures so as to deny income to the government?
Do you employ any tax evasion measures so as to deny income to the government?
But to be honest I can not see what Brian's tax status has to do with anyone other then him and HMRC - can you?
