"Domicile" is the place where an individual has a permanent home and to which he intends to return after being absent. It is the place at which an individual has voluntarily fixed his habitation, not for a special or temporary purpose, but with the intent of making a permanent home.
A domicile, once established, is not lost until all of the following three elements are met:

All income received during the period of Utah residency is taxable in Utah, regardless of the source of that income.
Utah residents who derive income from other states must pay taxes to Utah on both income from Utah and income earned in the other states. Utah residents who work in other states do not lose their residency solely by being absent from Utah. They are still required to file resident income tax returns in Utah on all income, regardless of source.
If a Utah resident pays an income tax to another state on income derived from the other state, Utah will allow a credit for taxes paid to the other state. For detailed information and examples of how to calculate the credit for tax paid to another state, click here.
Utah residents, who earn income in a state without an income tax, must pay tax to Utah for the income earned in the other state. No credit is allowed, because no tax is paid to the other state.
A Utah resident, a tenured college professor, teaches summer sessions at a university in Nevada. The professor's annual income is:
$25,000 – Summer stipend from university in Nevada
$70,000 – Salary from a college in Utah
$95,000 – Total Income
The professor would file a Utah tax return (form TC-40) and pay Utah tax on the full $95,000. All income earned by a Utah resident is taxable. In this case, the professor would not be allowed a credit for taxes paid to Nevada, because Nevada does not have a state income tax.
Similarly, a Nevada resident who derives income from Utah would be subject to Utah tax on 100 percent of the Utah earnings, because Nevada does not have an income tax.
Utah residents who travel abroad to work or who work out of state for extended periods, but leave their families in Utah, are likely subject to the Utah income tax on all income earned domestically and/or abroad.
A domicile, once established, is not lost until all of the following three elements are met:
The mere intention to abandon a domicile, once established, is not sufficient to create a new domicile. Before a person can be said to have changed his domicile, even though he manifests an intention to abandon the old domicile, a new domicile must be shown.
