Be aware that once you create a business account you can't revert to a personal account - you're stuck with it.

I don't see any benefits to creating a business account, but to the contrary you will miss out on some offers.

It's not necessary for tax purposes.

Note: Please be aware that once you've upgraded your personal account to a business

account, it won't be possible to revert back to a personal account.
