You will have met the tax home test if you did not have a tax home outside the relevant possession during any part of the tax year.
Your tax home is your regular or main place of business, employment, or post of duty regardless of where you maintain your family home. If you do not have a regular or main place of business because of the nature of your work, then your tax home is the place where you regularly live. If you do not fit either of these categories, you are considered an itinerant and your tax home is wherever you work.taxmap/pubs/p570-002.htm#en_us_publink1000221178
There are some special rules that provide exceptions to the general rule stated above.taxmap/pubs/p570-002.htm#en_us_publink1000221179
Disregard the following days when determining whether you have a tax home outside the relevant possession.
- Days you were temporarily in the United States as a student (see Student under Days of Presence in the United States or Relevant Possession, earlier).
- Days you were in the United States serving as an elected representative of the relevant possession, or serving full time as an elected or appointed official or employee of the government of that possession (or any of its political subdivisions).
You will not be considered to have a tax home outside the relevant possession solely because you are employed on a ship or other seafaring vessel that is predominantly used in local and international waters. For this purpose, a vessel is considered to be predominantly used in local and international waters if, during the tax year, the total amount of time it is used in international waters and in the waters within 3 miles of the relevant possession exceeds the total amount of time it is used in the territorial waters of the United States, another possession, or any foreign country.taxmap/pubs/p570-002.htm#en_us_publink1000221181
In 2009, Sean Silverman, a U.S. citizen, was employed by a fishery and spent 250 days at sea on a fishing vessel. When not at sea, Sean lived with his wife at a house they own in American Samoa. The fishing vessel on which Sean works departs and arrives at various ports in American Samoa, other possessions, and foreign countries, but was in international or American Samoa's local waters for 225 days. For purposes of determining bona fide residency of American Samoa, Sean will not be considered to have a tax home outside that possession solely because of his employment on board the fishing vessel.taxmap/pubs/p570-002.htm#en_us_publink1000221182
If you are moving to or from a possession during the year, you may still be able to meet the tax home test for that year. See Special Rules in the Year of a Move, later in this chapter.
