I don't think you can claim a deduction on something you haven't paid tax on, ie: Website registration. So unless you happen to live in the same state as the registration company you used, you probably didn't pay tax. Same goes for purchasing business items online and out of state. I always pass that stuff on to my accountant anyway. But as far as I know, you can't get taxes back on items you didn't pay tax on.
