I have heard different explanations about the need to pay taxes here and the amount of withholding. Everyone who makes inquiries with their employers seem to get different explanations.
Are you having problems with a particular regulation? I advise you to stop listening to their oral explanations. Get a copy of the relevant regulation that they are quoting and mail it or and fax it to me.
Please include your contact information.
I will examine the regulation and let you know what I think.
