I have a rental property in Florida, but live in California. Do I have to file a Florida state return?

"Do I have to file a Florida state return?"

Florida does not impose an individual income tax so there is nothing you need to file with the state.

Counties in Florida have the authority to levy an ad valorem tax on tangible personal property that is used in a business or rental real estate. The "$25k exemption" refers to an exemption of up to $25k in assessed value of the reportable tangible personal property used in a business or rental.

Form DR-405, if one needs to be filed, does not have to be filed via TurboTax. In fact, at least one county requires the form to be filed online from the county's web site and several others have their own, modified, version of the form. It would therefore be wise to consult your county property appraiser's web site before proceeding. A list of county property appraisers' web sites can be found here --> http://floridarevenue.com/dor/property/appraisers.html

In the event you need to file a Form DR-405 and would like to do so through TurboTax, then you should know that nothing will print (except an instruction sheet) unless assets were transferred or you manually entered assets in the DR-405 worksheet. [see screenshots]
