Florida does not have an individual state income tax, but does have corporate income taxes. Therefore, if you own this rental property as an individual, you would not owe any income tax on the rental income. But, if you have a business that owns the property, then your business may owe taxes. Here is a link to more information from the State of Florida website: http://www.stateofflorida.com/taxes.aspx
Florida does not tax personal income and never has. You can't file a tax return for Florida even if you want to, because no such forms exist for doing so.
What you paid for was the DR-405 which is filed with the *LOCAL* county courthouse if you have income producing non-real estate assets. So if you made the boo-boo of separating out your appliances to depreciate them separate, then those appliances are considered income producing equipment used in your business. You'll have to file the DR-405 at the local county courthouse every year, and the money you "think" you save by depreciating them separately, you'll end up paying to the local county in the form of a "tangible property tax" each and every year.
This is why I tell folks that you *DO* *NOT* save a single penny when you separate out your rental assets from the main structure so they depreciate more and faster.
