Your tax home is the single most important concept in travel nurse taxation — yet most nurses have never read the IRS definition. According to IRS Publication 463, your tax home is the city or general area of your principal place of business, regardless of where you maintain your personal residence. That distinction shapes your entire financial life as a traveling clinician.
The reason this matters: your tax home determines whether your agency's housing and meal stipends are tax-free reimbursements or ordinary taxable wages. A nurse with a valid tax home can legally exclude thousands of dollars per assignment from gross income. A nurse without one can face retroactive IRS reclassification of every stipend payment — turning a $90,000 year into a tax bill that reflects $115,000 or more.
What Is a Tax Home?
A tax home is your regular place of business or, if you have no fixed place of business, the place where you regularly live (IRS Publication 463). For travel nurses, this is almost always a specific city — usually where you maintain a permanent residence, hold a state license, and return between contracts. The IRS focuses on where you do business and where you bear ongoing housing costs, not where you were born or where your family happens to live.
The concept of being "away from home" is the legal trigger for tax-free treatment of travel expenses. When you work in Phoenix but your tax home is Dallas, you are away from home and the lodging and meal stipends your agency covers are legitimate reimbursements. Without a qualifying tax home, you are simply a worker who lives wherever they work — meaning all reimbursements are reclassified as wages and none of your stipends are tax-free.
The IRS Three-Factor Test
The IRS uses a three-factor test drawn from decades of Tax Court decisions to determine whether a taxpayer has a bona fide tax home. You do not need to pass all three, but meeting more factors — and meeting them clearly — builds a far stronger position if you are ever audited.
Factor 1: You Perform Business Near Your Main Home
The IRS expects you to do some work in the area you claim as a tax home. This does not mean full-time employment — per diem shifts at a local hospital, an active agreement with a nearby agency, or documented job applications in your home area all satisfy this factor. The key is that your home city is a genuine place of business, not just the city printed on your driver's license.
Factor 2: You Bear Duplicate Living Expenses
This is the most critical factor and the one most nurses either pass easily or fail entirely. You must be paying for housing at your home base while simultaneously incurring housing costs at your assignment location. Qualifying arrangements include an apartment lease in your name, a mortgage on a home you own, or rent paid to a family member at documented fair-market value. Leaving belongings in a storage unit does not satisfy this requirement — the IRS requires an actual ongoing housing expense.
Factor 3: You Have Not Abandoned Your Home
You must intend to return to your home base and actually do so. Returning between assignments, maintaining your driver's license and vehicle registration in your home state, and keeping your bank accounts and primary relationships there all support this factor. Nurses who chain assignments without ever returning — or who have permanently left their supposed home base — give the IRS grounds to say the home was abandoned.
What Disqualifies a Tax Home Entirely
The IRS calls a worker with no fixed home "itinerant." An itinerant worker can never be "away from home" because they have no home to be away from — meaning 100% of their income, including every stipend, is taxable wages. You become itinerant if you give up your home base for each assignment, maintain no ongoing housing cost there, or work in the same assignment location for more than one year (which converts that city into your new tax home).
The most reliable way to evaluate your situation is to check it against the three factors before your next contract begins. Our Tax Home Quiz walks through all three factors in eight questions and tells you exactly which ties are strong and which need reinforcement.
What a Valid Tax Home Is Worth in Dollars
Consider a nurse earning $34/hour in taxable wages plus a $1,800/month housing stipend and $55/day in meals on a 13-week contract. The stipends total roughly $9,785 over the assignment. In the 22% federal bracket plus 7.65% FICA and a 5% home state rate, those stipend dollars would cost approximately $3,375 in taxes if reclassified as wages. A valid tax home keeps that entire amount tax-free. Over two or three contracts per year, that is $6,000–$10,000 in after-tax income that depends entirely on whether your home base qualifies.
Frequently Asked Questions
Can I use my parents' address as my tax home?
Yes, but only if you pay fair-market rent there and can document every payment. Staying rent-free in a family home does not create duplicate living expenses — you are not bearing an ongoing housing cost that your assignment stipend is duplicating. To use a family member's home, create a written lease and transfer monthly rent via bank or check so every payment is traceable.
How long can I stay on one assignment before losing my tax home?
The IRS standard is that an assignment expected to last one year or more is no longer temporary. If your assignment extends to 12 months at the same facility or metropolitan area, that location becomes your new tax home and subsequent stipends become taxable. This is the primary reason most travel nursing contracts are structured at 13 weeks.
What records should I keep to document my tax home?
Keep your lease or mortgage statements, bank records showing rent payments, utility bills in your name at your home address, voter registration, driver's license, vehicle registration, and any evidence of per diem work near your home base. You should be able to produce at least 12 months of records showing continuous housing expense — ideally with dates that overlap your assignment periods. See our audit-proof tax home documentation checklist for a printable breakdown of every record to keep.
Do I still owe taxes in my assignment state?
Most likely, yes. You will owe income tax on your taxable wages in each state where you work. Your home state typically taxes your worldwide income but gives you a credit for taxes paid to other states, which prevents full double taxation. You will generally need to file a non-resident return in each assignment state and a resident return in your home state.
