Yes, there is no state filing status needed as you exist on a yearly basis.
The question I would ask is if you obtained an EIN from the IRS for banking purposes, under what status are you filing with the IRS? As a business, as a not for profit, or as a non-profit?
Obviously you are not a homeowners association but a statutory road (only) association, therefore you are not responsible to repair an owner's building or their driveways.
This brings up another question; why do the insurance companies classify us as a homeowners association charging us a higher rate than just for the roads? Why aren't insurance companies paying to road associations for emergency road repairs?
