What Is a Tax Home?
Tax home is a US federal tax concept for the general area of a taxpayer's main place of business, employment or post of duty.
Also known as: IRS tax home, Foreign tax home.
How Tax Home works
Tax home is the place the Internal Revenue Service treats as the centre of a person's working life, namely the general area of the main place of business, employment or post of duty, and the concept decides both whether travel expenses are deductible and whether a US citizen or resident abroad can claim the foreign earned income exclusion. When work offers no regular or main place of business, IRS guidance treats the place where the person regularly lives as the tax home, and a person with neither a main place of business nor a regular home base is considered an itinerant whose tax home is wherever the work happens. For the foreign earned income exclusion a foreign tax home is required, yet IRS guidance recognises no foreign tax home for any period during which the person's abode remains in the United States, with a narrow exception for certain Armed Forces personnel in combat zones. Abode is assessed on the facts, including where home, family and economic ties remain, so a nomad who keeps a US base and US-centred life may fail the abode rule despite long periods abroad. Tax home is a separate condition from the bona fide residence test and the physical presence test, both of which require their own analysis, subject to later amendments and the facts of each year.
Tax Home vs Tax Residency
Unlike tax residency, which decides whether a country taxes a person on worldwide or only domestic income, tax home is a US test locating the main place of work, used for travel deductions and foreign earned income exclusion eligibility. A US citizen remains taxable in the United States whatever the tax home, while residency abroad is governed by each foreign country's own law.

| Main consequence | Travel deductions and foreign earned income exclusion eligibility | Scope of taxable income, filing duties and treaty access |
Example
Illustrative example: A US citizen works remotely as a designer and spends most of the year moving between rented flats in Country A and Country B, with no fixed office. The designer keeps a family house in the United States, returns there between trips and keeps bank accounts, a driving licence and voter registration there. Because no main place of business exists, IRS guidance looks at where the designer regularly lives, and because the abode appears to remain in the United States, the designer may lack a foreign tax home and therefore fail one condition of the foreign earned income exclusion. Another designer who signs a long-term lease in Country A, moves family life there and works from a local co-working space would present stronger facts for a foreign tax home. The second designer still has to satisfy the bona fide residence test or the physical presence test separately, and remains subject to US filing obligations as a citizen.
Common misconception
Myth: Spending most of the year outside the United States automatically gives a nomad a foreign tax home.
Reality: Days abroad do not settle tax home on their own, because IRS guidance recognises no foreign tax home for any period during which the abode remains in the United States.
Frequently asked questions
What is a tax home for the IRS?
A tax home, for IRS purposes, is the general area of the main place of business, employment or post of duty, which may differ from the place where a family home is kept.
Can a digital nomad have a tax home?
A digital nomad without a main place of business generally has a tax home where the nomad regularly lives; with no regular home base either, the IRS treats the nomad as an itinerant whose tax home is wherever work is done.
Why does tax home matter for the foreign earned income exclusion?
The foreign earned income exclusion requires a tax home in a foreign country, and IRS guidance recognises no foreign tax home for any period during which the taxpayer's abode is in the United States.
Is tax home the same as tax residency?
Tax home is not the same as tax residency: tax home locates the main place of work under US rules, while tax residency determines which country may tax a person's income under each country's domestic law.
