Florida Aircraft Sales/Use Tax issue – AK Resident

Any help appreciated here. I bought an airplane from a dude in Vermont in December 2022, I was on Military orders to Florida as an Alaska resident and purchased the aircraft under an Alaska LLC. The aircraft was not in Florida when money changed hands, I’m an Alaska Resident on Mil orders, with an airplane in a non-Florida LLC…oh and I was using the aircraft to build hours for the airlines (ie. Flight training) and now I’m being taxed for a purchase that isn’t eligible for sales tax in the state I’m a resident of and the state where the company owns the aircraft (Alaska does not have aircraft sales/use tax). Florida department of revenue is now auditing me for sales and use tax on that aircraft purchase. The total amount of tax they’re coming after is roughly $6700.

The other part of this is that on the FAA bill of sale, I put my mailing address in Florida so I could receive the registration in the mail at my address in Florida. Little did I know this was probably a $6.7k mistake. Does anyone know if my argument will hold water if I do a Bill of Sale amendment? I’m thinking not.

Has anyone run into this before? Or have any trusted military background or veteran tax lawyers? I’m getting an appointment with the JAG but trying to explore all my options and I know a lot of you are super connected or knowledgeable on this stuff. Thanks!
