I don't understand why "paying" your spouse thru paypal can possibly be financially beneficial ? Moving money from your personal account to your wife's personal account has no benefits that I can think of ... it is like moving money from one pant pocket to another. You should be moving personal money from the business account to your personal account and then you can move it any way you want to your wife. Never pay personal expenses out of a business account ... doing so will make an IRS financial audit miserable.
Now does your spouse work for your business ?
