I am trying to create a iTunes account for my younger cousin, but he does not have a credit card (he's too young). Tried Google, seems outdated on this issue.
You must first go to iTunes store in iTunes then choose App Store, then select 1 free app (this is the most important steps) and try to get that app. When you try to download this free app iTunes ask you to enter your account so you must press Create New Account and fill the forms but in the Provide a Payment Method steps because you try to download free apps you see below form instead of normal form:
You must choose None for your Credit Card.
As others have said, you can create an account by first trying to purchase a free app. This is also documented at Apple's own Knowledge Base: Create an iTunes App Store account without a credit card
(I found the link above in this question: How to activate new iPad without disclosing credit card number? )
