Use the correct legal concept before choosing documents: permanent home, state tax residence and federal tax home serve different purposes.
Domicile asks about the permanent home
Domicile generally combines an actual home with intent to make it the permanent or indefinite home. A temporary absence can leave an existing domicile in place. Formal records are evidence, not a substitute for the underlying facts.
State tax residence may use another route
A state can tax someone as resident under a statutory test even when their domicile is elsewhere. New York’s abode-and-day test illustrates why proving Florida domicile does not answer every residence question.
Federal tax home follows different rules
For business travel, tax home generally concerns the main place of business or employment. FEIE adds foreign-tax-home and abode requirements. A declaration of domicile does not automatically create deductible travel or qualify overseas wages for exclusion.
Sort your question before contacting support
For mail delivery, ask about the mailbox and authorization. For a license, ask the issuing agency about residential documents. For a tax return, give the preparer your home, work, income and travel facts. The nomad definitions guide connects these questions for people travelling abroad.
