The tax home is the concept that separates travel nurses who keep $20,000+ in tax-free stipends every year from those who unknowingly hand it all back to the IRS. And yet most travel nurses have only a vague idea of what it actually means.
Here’s the full picture: what a tax home is, what qualifies, how to document it, and what happens if yours doesn’t hold up to scrutiny.
What Is a Tax Home?
Despite what the name implies, a tax home isn’t necessarily your “home” in the emotional sense — it’s your primary place of business in IRS terms.
The IRS defines your tax home as the city, town, or general area where your regular place of business or employment is located. If you don’t have a regular or main place of business, your tax home is where you regularly live.
For most people in traditional jobs, this is simple: they live near where they work. For travel nurses who move every 13 weeks, it requires more deliberate planning.
Why it matters: The IRS only allows travel nurses to receive tax-free housing and meal stipends if they’re working away from their tax home. The logic is that you’re incurring duplicate living expenses — paying to maintain your regular home AND paying for housing at your assignment location. Without that duplicate burden, there’s no tax-free status to justify.
The Three-Factor IRS Test
The IRS doesn’t just take your word for it. They use a three-factor test to determine whether you have a legitimate tax home. You don’t need to pass all three, but you need to pass at least two — and the more factors you meet, the stronger your position.
Factor 1: You Perform Part of Your Business at Your Home Base
Do you work (even occasionally) in the area you claim as your tax home? For a travel nurse with a home in Ohio who does local per diem shifts between assignments, this is easy to document. If you never step foot in your home state for work, this factor doesn’t apply — which means you need both of the remaining factors.
Factor 2: You Have Duplicate Living Expenses
This is the most important factor. You must have real, ongoing costs at your home base while also paying for housing at your assignment location.
What counts as a duplicate living expense:
- Paying rent or a mortgage at your home address
- Paying utilities at your home (even if reduced while away)
- Maintaining an active lease or ownership stake in property
What doesn’t count:
- Living with parents for free
- A storage unit
- Using a friend’s address as a mailing address with no actual costs
The IRS wants evidence you’re paying for two places to live — not that you have a convenient mailing address.
Factor 3: You Haven’t Abandoned Your Home Base
Do you maintain genuine ties to the place you call your tax home? This is about the totality of your relationship with that location:
- Family members live there (spouse, children, parents you support)
- You return there during contract breaks
- Your driver’s license, vehicle registration, and voting registration are there
- Your banking and financial accounts list that address
- Your professional licenses use that address
The more of these that apply, the stronger your tax home claim.
What Does NOT Qualify as a Tax Home
Many travel nurses fall into one of these traps:
The parents’ house where you don’t pay anything. If you claim your childhood home as your tax home but pay zero rent, have minimal belongings there, and rarely return — the IRS is unlikely to accept it. A tax home requires real ongoing costs.
A mailing address service. Some nurses use mailbox services or registered agent addresses to establish a “residence” in a tax-friendly state. Without actual costs and ties, this doesn’t create a tax home.
A state you’ve never actually lived in. Your tax home must be a place where you genuinely have ongoing costs and maintain ties. Simply registering a vehicle in Nevada doesn’t make Nevada your tax home.
A roving lifestyle with no home base. If you go straight from assignment to assignment with no fixed residence you’re paying for between contracts — you may be what the IRS calls an “itinerant worker.” Itinerant workers have no tax home, which means all your income (including stipends) is taxable. This is legal; it’s just not tax-efficient.
How to Establish a Strong Tax Home
If your current situation is shaky, here’s how to build a defensible tax home:
Rent an apartment or room in your home base area — even a modest one. The IRS doesn’t require you to maintain a full household, just to have real expenses. Some nurses rent a room from family at fair market value, paid consistently and documented.
Keep your official records tied to that address. Driver’s license, vehicle registration, voter registration, banking, professional licenses — all pointing to the same address sends a clear signal.
Return there regularly. Between assignments, go home. Document it. The pattern of returning matters.
Pay rent or mortgage even while on assignment. This is the clearest evidence of duplicate living expenses. If you’re sublet the whole place while you’re away and pocket the income, you may have undermined the duplicate expense argument.
Documenting Your Tax Home
Good documentation protects you if you’re ever audited. Keep:
- Lease agreements or mortgage statements showing ongoing payments at your home address
- Utility bills at your home address, even if reduced while on assignment
- Bank statements with your home address
- Pay stubs from your home agency, if you do local per diem work
- Flight records or gas receipts showing trips back to your home base
- Dated photos of your living space at home (timestamped photos in your phone’s photo library work)
- Any records showing family ties — school enrollment for children, joint lease, etc.
You don’t need to produce all of this proactively — but if you’re audited, you want to be able to show a coherent picture.
The Stipend Calculation Isn’t Just About Having a Tax Home
Even with a qualifying tax home, your stipends are only tax-free up to IRS General Services Administration (GSA) per diem rates. These rates vary by assignment location — they’re higher in San Francisco than in rural Arkansas.
If your agency pays stipends above GSA rates for your assignment location, the excess is taxable income — regardless of your tax home status.
Check current GSA rates at gsa.gov/perdiem. Compare them to what your agency is paying. Any amount above the GSA rate should appear on your W-2 as taxable wages.
What Happens If the IRS Challenges Your Tax Home
If you’re audited and your tax home doesn’t hold up, the consequences are:
- Your stipends become taxable income — often for multiple years
- You owe back taxes on the reclassified income — potentially significant amounts
- Interest accrues from when the taxes were originally due
- Penalties if the IRS determines you were negligent or willful
This is not meant to scare you — the vast majority of travel nurses are never audited. But the risk is real enough that the tax home question deserves genuine attention, not creative paperwork.
Frequently Asked Questions
Can I claim my parents’ house as my tax home? Yes, if you pay fair market rent and maintain genuine ties there. No, if you live there for free or use it as a mailing address without real costs. The IRS looks at whether you’re actually incurring duplicate living expenses.
I move every 13 weeks and don’t maintain a home base. Am I an itinerant worker? Potentially. If you have no fixed residence you’re paying to maintain, you may not have a tax home — which means your stipends are taxable. It’s worth discussing with a CPA who works with travel nurses.
Does my tax home state affect my state income taxes? Yes — your tax home state is typically your resident state for tax purposes, meaning it taxes all your income. This matters when choosing a tax home state: states with no income tax (Florida, Texas, Nevada, etc.) can result in significantly lower overall tax liability.
How long do I need to be away from my tax home for stipends to be tax-free? The IRS requires that your assignment be temporary — generally expected to last less than one year. If an assignment is expected to last more than a year, or actually extends beyond a year, it may no longer qualify as temporary and the tax-free treatment could be lost.
What if I’m on a year-long contract? Year-long contracts are a gray area. An assignment “expected to last” more than 12 months loses its temporary status from day one. An assignment that starts as short-term but gets extended past 12 months generally loses tax-free status at the point it’s expected to continue beyond a year. Document the original contract terms carefully.
Should I consult a CPA about my tax home? For your first year, absolutely. A CPA who works with travel nurses can evaluate your specific situation, help you document your tax home properly, and flag any risks. The cost of good advice is typically a fraction of what you’d owe if your tax home was successfully challenged.
