There is "A Lot" more to having a Montana LLC than a simple set up. In addition, registering a vehicle out of state has its own issues.
A Montana LLC requires:
1) An agent
2) An instate address for service
3) There can be tax issues
4) Cost - It varies by attorney, but range from $1000 - 2000 to set up - depending on title and how many vehicles the LLC holds. There are yearly maintenance fee's also - $100 - 200 year.
There can be other issues:
1) Insurance:
A) Some companies will not issue policy's
B) Without a legal address and/or drivers license in the LLC state - Insurance coverage can be denied after a claim
C) Some companies charge a premium for coverage.
2) Police:
A) Police will cite a driver and vehicle if they suspect fraud as the reason the vehicle is registered out of state - make owner prove otherwise!
B) Attorneys in Montana use their office addresses as Service address for hundreds of LLC's. The cops know this, and will cite you.
C) Fee's - Cops, DMV's, Tax Boards and Courts know all about Montana LLC's. They want the money and will throw the book at an LLC owner.
3) Title - Vehicles Owned by an LLC are titled as owned by "XXXXX, LLC." Many states recognize this and will investigate the LLC ownership to determine if it is legitimate or a "Dodge" when a vehicle is sold or re-titled. If determined to be a dodge, the owners will be subject to penalties, back taxes, etc.
4) With license plate readers on police cars becoming more common, and the power of computers, determining if an LLC is legitimate is very easy. Especially on a vehicle driven daily or parked on the street.
5) Drivers License - When operating a vehicle that is registered (especially a vehicle owned by an LLC) in a different state than the state the operators drivers license is issued, cops will issue a ticket and make driver sort it out with courts and DMV.
One may suspect "WEE" may of had a Montana LLC at one time...? They can work, and did work, and there are people I know that have them still, but the risk is high to get caught, and getting higher everyday. In Nevada, the DMV website now has specific information about Montana LLC's and what happens if caught!
If you have a friend of relative in Montucky, you could use their address, but remember the insurance issues, cops and DMV can trip you up.
If you decide to go the Montucky LLC route, I may know an attorney...
Keep your eyes open if you decide to go this route.
