No annual property tax, registration fees, etc. on aircraft in CO. A 3% state sales/use tax when first purchased. Local municipalities and counties can have their own sales/use taxes in addition to a few special tax districts for things like mass transit. As I'm located in an unincorporated area of a county without a sales/use tax, I only had to pay the state sales/use tax.
I guess I have it pretty good in CO compared to other states.
