MS HB490

Exempts sales of fixed-wing aircraft from Mississippi sales tax if the aircraft is exported from the state within 30 days and registered and first used in another state

Amends Section 27-65-101 of the Mississippi Code of 1972, which governs industrial exemptions from sales taxation

Adds fixed-wing aircraft to existing exemptions that already cover semitrailers, trailers, boats, travel trailers, motorcycles, all-terrain cycles, and rotary-wing aircraft (which require 48-hour export)

Fixed-wing aircraft receive a longer export window of 30 days compared to the 48-hour requirement for other exempt vehicles

Preserves any existing claims, assessments, or causes of action for taxes due before the act's effective date
