Step Two, Part One: iTunes Connect

It is best to start with the paperwork, so while you are working on your project Apple has time to process it. Once you have been approved as an iPhone Developer, you gain access to iTunes Connect, the page where you will be able to upload your applications and manage your finances and contracts. You can use your Apple ID to log in.

Before you can sell anything in the AppStore, you have to provide Apple with contact, banking and tax information. There is an option called "Contracts, Tax, & Banking Information" doing just that. I strongly suggest you fill out these forms as soon as possible. I don't know how long the standard wait time is, but I had to wait 3 weeks after these were filled to see my contracts listed as active. You may have to ask your bank about some details in the Banking section, but otherwise both that and the contact info section is pretty straightforward. The Tax section is another matter.

There are two cases here: you either live in the US or not. If you do, you will have to fill out the form W9 using the iTunes Connect site, and they will do the rest for you. If you do not, you will have to fill out a form called W-8BEN online, but they will send a copy of the form to your e-mail address, and you have to print it, sign it, and mail it. That sucks, so I decided to scan it instead, and sent it to iTStax@apple.com. They accepted it within 2 days, and while I cannot guarantee that this will work for you, I prefer electronic mail because of... environmental considerations. There is a certain field on this form that just makes no sense: US taxpayer ID. How am I supposed to have one if I am not a US citizen? I have read that you can get one from IRS, but there is an even simpler solution, which worked for me: fill in 000000000, and mark SSN. If you are an individual developer, you probably only need to mark 9a of the other checkboxes. The form you print will have a "Capacity in which acting" field, you can write Individual or leave it empty (that's what I did). If you are curious, this is how the form looks (from the IRS website).

Now you will have to wait... I didn't see it mentioned anywhere, but your application won't go on sale until your contracts are active, and it will take anywhere from 2 days to a month to have them activated. So be patient.
