I may have mentioned in passing, in some other thread, that I have been dealing with the US IRS. My application for an ITIN (a personal identification number that allows me to claim tax exempt status as a foreign national under an existing Canada-US treaty) was rejected twice: the first because I (almost literally) forgot to dot an "i" on the application form (my bad); and the second because of their mistake (their bad.) So I sent in the third application (after talking, yet gain, to a helpful IRS phone agent - they have all been very friendly and willing to help). Anyhow, several weeks ago I finally received my ITIN. This then allowed me to update my info for one of the online sellers of my book - in this case e-books - which in turn then allowed them to finally start making royalty payments. (I'd had them hold off until I got my ITIN - not wanting to then go through the hassle of applying to the IRS to get the 30% withholding tax back. For reasons unknown, other sellers neither required an ITN, nor did they withhold anything - the info that I supplied when registering with them (essentially the same as on a formal ITIN application) being enough for their system to do so.)
Anyhow, the amount of the now-flowing royalty is small (enough for a fine bottle of wine), but it's still neat to get nevertheless.
So yeah, as Randy says, just keep buying them folks - and if you are ever up my way I'll even let you drink the profits with me!
