A generous gift and estate tax exemption (currently $5.45 million) means only a small percentage of families are subject to federal estate taxes. But it’s important to consider state estate taxes as well. Although many states tie their exemption amounts to the federal exemption, several states have exemptions that are significantly lower — in some cases $1 million or less.

One way to avoid this tax burden is to retire in a state that imposes low or no estate taxes. But moving to a tax-friendly state doesn’t necessarily mean you’ve escaped taxation by the state you left. Unless you’ve cut all ties with your former state, there’s a risk that the state will claim you’re still a resident and are subject to its estate tax.

Even if you’ve successfully established residency in a new state, you may be subject to estate taxes on real estate or tangible personal property located in the old state (depending on that state’s tax laws). And don’t assume that your estate won’t be taxed on this property merely because its value is less than the exemption amount. In some states, estate taxes are triggered when the value of your worldwide assets exceeds the exemption amount.

If you’re relocating to a state with low or no estate taxes, consult your estate planning advisor about steps you can take to terminate residency in the old state and establish residency in the new one. Examples include acquiring a residence in the new state, obtaining a driver’s license and registering to vote there, receiving important documents at your new address, opening bank accounts in the new state and closing the old ones, and moving cherished personal possessions to the new state.

If you own real estate in the old state, consider transferring it to a limited liability company or other entity. In some states, interests in these entities may be treated as nontaxable intangible property.
