IF she's an employee:
you might lose writing off some of her expenses
higher accounting costs for employees paperwork/compliance etc

able to write off all business related expenses
a lot simpler accounting/paperwork

I can't think of any advantages, but less less flexibility for you to be active in the business (like talking with banks, signing stuff, estate planning...)
If you have an accountant and/or a Tax preparer, it's a good idea to ask them. If you don't have one, you might want to invest a few hours worth of consulting on the matter, so that they can give you an answer based on your situation.
