What Is Your Domicile?

Domicile is one of those words that courts and lawyers toss around and expect people to understand. But its meaning can be tricky. Simply put, your domicile is your home—the state you consider your permanent residence. If you aren't living there right now, then it's the place you intend to return to and make your home indefinitely. You can have more than one residence, but only one domicile.

Why Your Domicile Matters

When or why does the question of domicile arise? Your domicile can affect many legal issues, especially taxation.

Most commonly, it comes up after a state's taxing agency (department of revenue or taxation) rules that someone is domiciled in the state. A taxpayer (or the taxpayer's surviving family members) who wants to dispute that determination must go to court.

Domicile and State Income Tax

Most states impose an income tax on people who live or work in the state. If you are domiciled there, you pay tax on all of your income, no matter where you earned it; if you're not, you pay tax only on income derived from sources within the state. (Even if your domicile is elsewhere, however, you may be assessed tax like a domiciliary if you are a "resident" under state law.)

Domicile and State Estate Tax

Fewer than 20 states impose their own estate tax—that is, a state tax on assets left at death. If you are domiciled in one of these states (such as New York or Massachusetts), your survivors might end up paying a tax bill that would not have been due had your legal domicile been in a non-taxing state (such as Florida or Arizona).

Domicile and Probate

If surviving family members need to start a probate court proceeding to distribute your assets to the people who inherit them, they must begin it in the state (and county) where you were domiciled at the time of your death.

Domicile and Divorce

All states have residency requirements that one must meet to get divorced in that state's courts. Even when the laws don't use the term "domicile," courts in many states have held that "residency" means essentially the same as domicile in this context. In other words, most states require the person filing to have been living in the state for the required amount of time before they file for divorce and that the person plans on staying there indefinitely.

Factors That Affect Where You're Legally Domiciled

Some factors that indicate where the law considers you to be domiciled include where you live, vote, register your car, and where your spouse or partner and children live. But domicile is fundamentally a question of your intent—which state do you consider your permanent home?

Example: Harry and Simone have lived in New Jersey most of their lives. They've owned their New Jersey house for 30 years, their tax returns list their New Jersey address, and their wills declare that they're residents of New Jersey. But they now spend six months of the year in Florida, own a house in a resort community there, vote there, and have a car registered there. Where is their legal domicile? If there's a legal battle, the outcome will depend on proof of which state they consider their permanent home. Unless they've transferred most of their important activities (see below) to Florida, there's probably not enough evidence to show that they intended to change their domicile from New Jersey to Florida.

Establishing a New Domicile

If it isn't clear which state is your legal domicile, decide which one you want it to be, and then take steps to make sure that state will legally be considered your domicile.

Owning a home in a state, or spending most of your time there, isn't enough to make it your domicile. Because the crucial factor is your intent, take every opportunity to show or declare that the preferred state is your permanent residence.

For example, it's important to use your in-state address for your:

• tax returns
• insurance records (homeowner's, car, and life)
• passport
• credit card accounts
• Social Security
• bank and brokerage accounts
• membership organizations

In your estate planning documents, including your will, living trust, powers of attorney, and healthcare directive, you can also make an explicit statement as to which preferred state is your domicile. Most wills, for example, begin with a statement of domicile. Make sure the documents comply with your preferred state's laws.

Here are some more steps you can take to show that your life is centered in the preferred state:

• If the state requires special tax returns—for example, Florida requires intangible personal property tax returns—file them.
• Register to vote there.
• Get a driver's license in the state.
• Register your vehicles (and your dog, if you have one) there.
• Open checking and savings accounts and a safe-deposit box in the state.
• Get a library card there.
• Join a gym or social group.
• Consult local professionals such as doctors, dentists, lawyers, tax preparers, and accountants.
• Contribute to or volunteer with local charities.
• Buy a home there and claim it as your homestead for property tax purposes.
• Change your billing and shipping addresses for all subscriptions and online services (such as Amazon and streaming services).
• If the state allows it, file a statement of domicile with the county clerk.

Giving Up an Old Domicile

It's not enough to take these kinds of steps to establish a new domicile; you must also show that you intended to give up the old one. So these actions are also important:

• If you must file a state income tax (or other) return in another state (for example, because you have income there), file as a nonresident.
• Sell your home in the state where you used to live, or rent it out when you're not there.
• Don't spend a lot of time in a state that was formerly your domicile.
• Don't work or run a business in a state that you don't want to be considered your domicile.
• Move valuable items and items of personal significance out of your former residence.
• Cancel memberships (country club, gym) in the old state.
