If writing novels is 10% inspiration and 90% perspiration, then selling them is 10% marketing and 90% utter confusion.
Call me old fashioned, but I'm used to doing things in a set order.
If I want to sell a product, I figure I should do it thusly:
1. Make Product
2. Get Taxes/Paperwork In Order so it's all official
3. Sell Product
Not so in the USA. In the USA, my experience is I need to swap 3 & 2 around.
The lovely tax expert I've been dealing with in Canada (which is a tautology because all Canadians are lovely. You're welcome,) advised me that until I have an active account with Amazon (ie, selling my ebooks to readers in the US) the IRS will reject my ITIN application.
Oh yes, and the IRS can take between 6 - 8 weeks to process the application. Then they may reject it. I've heard from writer friends that they can and do reject applications, sometimes without giving any reason.
I need to eat another curry pie to soothe my nerves.
