A domicile is a homestead that an individual has established as a fixed and permanent home.

Definition and Examples of a Domicile

The Internal Revenue Service uses "domicile" as another way to refer to where you live. For many people, this is a straightforward definition—it's the home, apartment, or other living space you reside in.

However, others have more complicated situations that involve multiple homes and splitting time between different regions. For these individuals, a domicile is the one place they have chosen as their primary residence for tax and legal purposes. You can not have more than one domicile.

Differentiating between a home and a domicile can be somewhat subjective, but objective actions can indicate your intention. Your domicile is:

  • The state to which you pay state income taxes
  • The state and county where your will would be probated and your estate would be administered
  • The state to which your estate would pay any estate and inheritance taxes
  • The state whose laws govern the enforcement of judicial orders

How a Domicile Works

Establishing a domicile depends on meeting specific criteria. Certain actions can give evidence of an intention to change your domicile. None is an absolute requirement, other than the one for physical presence. You have to commit to enough of them, however, to convince state authorities that you have truly moved your domicile.

You can have only one domicile at a time, no matter how many residences or homes you own. You retain your domicile until you legally establish another.

Requirements for Changing Your Domicile

A change of domicile requires:

  • Abandonment of a prior domicile
  • Physically moving to, and residing in, the new locality
  • Intent to remain in the new locality permanently or indefinitely


Your domicile doesn't change if you move to a new location on a temporary basis.

Move Your Property and Possessions

One step toward establishing a domicile would be to purchase or lease property in the new state. You must furnish it as a permanent residence, as opposed to a vacation place. Keep your family heirlooms, furniture, and keepsakes in the new state.


Failure to move items with strong sentimental value, such as the family picture albums, suggests a lack of intent to change domicile.

Stay for an Extended Time                     

You must stay in the new state for at least 183 days per year (50% of the year). This is the most important requirement, and it's an ironclad rule for tax purposes in some states. For example, New York considers you to be a resident for tax purposes, regardless of your intentions, if you maintain a residence there and spend more than 183 days per year there.


Keep a calendar so you can show when you were in the new state each year.

Identify Yourself

Obtain a driver’s license in the new state and register your cars. You should also register to vote in the new state. Some states have processes in place to apply for a homestead.

Establish Professional Relationships

Go to doctors, dentists, lawyers, and other professionals in the new state, and have your records moved there from the old state. Phone bills, utility bills, and credit card bills can all provide evidence of where you're living (and where you were living). Move bank accounts and safe deposit boxes to your new state domicile.

Establish Social Relationships

Join organizations such as clubs and religious groups in your domicile state. Become active with local charities. Arrange for family gatherings in the new state instead of your old state if possible. Subscribe to local newspapers, and cancel subscriptions in your old state.

File Official Documents

File your federal income tax return with the appropriate IRS service center, and show your new state as your address. You might also have to file a declaration of domicile if your new state has such a procedure.

Change legal documents such as wills, estate plans, and trusts to reflect residency in the new state. Update the address on your passport to your new state of residence.

Tell Your Friends and Businesses

Send notifications of a change of address to family, friends, business associates, professional organizations, credit card companies, brokers, and insurance companies.

Use your new state as a home base. When you travel, leave from and return to your new state.

Cut Ties With Your Old State

Not only must you adopt a new domicile, but you must abandon your old domicile. A lot of this is common sense when you're moving from one place to another. Don’t register your car in Pennsylvania to get lower insurance rates, for example, if you want to be a resident of Florida to escape Pennsylvania's income tax.

These are some other steps to consider taking in your former state of domicile:

  • Have your name removed from the voter registration list.
  • Turn in your driver’s license.
  • Pay income tax as a non-resident (if applicable).
  • Marke your last state income tax return “FINAL” (and using the new state’s address).
  • Spend as little time in the old state as possible.
  • Close accounts in the old state.
  • Change all club membership, religious affiliations, and social affiliations to “non-resident” status.

Key Takeaways

  • A domicile is a permanent residence for the purposes of taxes and other legal issues.
  • You can only have one domicile at a time, and you don't lose a domicile until you establish a new one.
  • There is a subjective element to determining your domicile, but you can influence the judgment through steps like registering to vote, getting a new driver's license, and storing sentimental items in your new domicile.
