Many new RVers assume that using a mail forwarding service automatically establishes legal residency in a state, but domicile involves much more than where your mail goes. Your domicile determines which state’s laws govern your taxes, voting, jury duty, estate planning, and even which courts have jurisdiction if legal issues arise. Simply having a Texas or South Dakota mailing address doesn’t make you a legal resident there.
True domicile establishment requires demonstrating intent to make that state your permanent home base. This typically means taking concrete steps: registering to vote, obtaining a driver’s license, registering your RV, opening a local bank account, and sometimes even filing a declaration of domicile. The key legal test is where you intend to return when you’re not traveling — not just where your packages get delivered.
The practical consequences show up in unexpected places. If you face a lawsuit, courts will look at your actual domicile to determine jurisdiction. Estate planning documents need to comply with your domicile state’s laws, not necessarily where your mail service operates. Some states are more aggressive than others about challenging questionable residency claims, especially for tax purposes.
Before choosing a domicile state based on tax advantages or mail forwarding convenience, research the full legal requirements for establishing residency there. Consider consulting with an attorney who specializes in RV domicile issues, particularly if you have significant assets or complex tax situations. The goal is creating a defensible legal position, not just a convenient mailing address.
