Sales tax due from seller?

Hello. I live in Illinois. I am in the process of selling my
Cherokee 180. Does anyone know if there are sales tax implications
for the seller? Does it matter if I sell the plane in-state,
out-of-state, or to a corporation?

When I purchased, I bought the plane from an individual who lived in
Illinois (and based the plane here), so no sales tax was due.

Thanks,
Nathan
