You need to speak to an accountant and/or tax attorney. This question involves many different aspects that cannot adequately be addressed in this format.
Your principal place of business for yax purposes is not what you arbitrary put on the State's website. It is where you principally operate the business regardless of what you place on sunbiz.
Florida has broad homestead protections. If you own your home and it is your primary residence, there are only limited circumstances in which your home may be at risk (for example, tax liens, liens connected to work performed on the property, and your mortgage lender).
Your principal place of business registered with the Division of Corporations is supposed to be the location where you actually conduct your business, not an address of your attorney. Simply listing your home address as your principal place of business is not going to place your home in risk. However, additional issues may arise, such as zoning issues and business tax receipt/occupational license issues.
I would advise consulting with an attorney with experience in small business matters to discuss your particular situation. As far as the tax issues are concerned, you should speak with a tax attorney or CPA for advice.
