Things to note about a Paid Books Account
You'll need an Apple ID.
You can't change from a Free Books account to a Paid Books Account.
In order to receive payment for your books, you'll need to submit your banking and US tax details.
You no longer need an ISBN to sell books (as was previously the case).
Apple works with a number of approved aggregators who can format, submit and market your book for you (for a price).
Apple take a 30% cut of any sales you make the through the iBooks Store.
So how do I get a U.S. Tax ID?
If I sell my books do I have to pay any further money or royalties to Book Creator?
No. We have no copyright or royalty claim to any books you publish.
