Most full-time RVers automatically choose Florida, Texas, or South Dakota for their legal domicile because “everyone does it.” But here’s what nobody tells you: your choice of domicile state can cost or save you $2,400+ annually in ways that have nothing to do with income taxes. The hidden costs lurk in insurance rates, vehicle registration fees, and voting complications that add up fast.
Take vehicle registration: Florida charges $225+ annually for large RVs, while Montana charges just $30 for the same rig. Insurance rates vary wildly tooโthe same RV policy costs 60% more with a Florida address than a Montana one due to hurricane risk and fraud rates. One couple I know saves $1,800 per year just by switching their domicile from Florida to Nevada, with identical coverage and no change in their travel patterns.
Here’s the breakdown most domicile services won’t share:
- Nevada: No income tax, low registration fees ($33), reasonable insurance rates
- Montana: Excellent for expensive RVs (no sales tax on purchases over $300k), but watch out for insurance increases
- Tennessee: No income tax, moderate fees, but requires annual safety inspections
- Wyoming: Hidden gem with low costs across the board, but limited mail forwarding options
The biggest shock? You can legally change domicile states anytime without penalty. Most RVers stick with their first choice for years, bleeding money unnecessarily. Run the numbers annuallyโyour domicile choice should evolve with your situation, potentially saving thousands.
