The Tax Home Rule, Explained
Your stipends are only tax-free if you maintain a "tax home." This page explains what that means, the three IRS factors that decide it, and the mistakes that turn a $1,900/week contract into a much smaller one.

| Factor | What it means in practice |
|---|---|
| 1. Business connection | You perform part of your work in the area of your main home and live there when you do — or your main home's area is where you've historically earned the bulk of your income. |
| 2. Duplicate living expenses | You genuinely pay for two places to live — rent or mortgage at home plus housing on assignment. This is the factor the IRS weighs most heavily alongside the first. |
| 3. Abode | You keep ties to the home area: a driver's license, voter registration, bank accounts, family, the place you return to between assignments. |
The one-paragraph version
Congress lets employers reimburse travel expenses tax-free for people who travel away from home for work. Your "home" for this purpose is your tax home — the general area where you regularly work and earn most of your income. If you keep a genuine tax home and pay to live in two places while on assignment (an apartment back home plus housing on the road), your stipends are reimbursements, not income. If your tax home dissolves — say you go nomad, let the lease go, and take back-to-back assignments in the same city — the stipends become taxable wages retroactively, plus penalties. The IRS has pursued exactly this, and agencies are required to ask about it.
The three IRS factors
IRS Publication 463 lays out a test with three parts. You generally need to satisfy at least two of the three — the first being the most important:
| Factor | What it means in practice |
|---|---|
| 1. Business connection | You perform part of your work in the area of your main home and live there when you do — or your main home's area is where you've historically earned the bulk of your income. |
| 2. Duplicate living expenses | You genuinely pay for two places to live — rent or mortgage at home plus housing on assignment. This is the factor the IRS weighs most heavily alongside the first. |
| 3. Abode | You keep ties to the home area: a driver's license, voter registration, bank accounts, family, the place you return to between assignments. |
Satisfy 1 and 2, and you're on solid ground. Satisfy all three and you're bulletproof. Satisfy only one — typically only #3 — and your tax home is considered wherever you actually work, which makes your stipends taxable.
Six mistakes that quietly break a tax home
1. Giving up the lease "to save money." No housing costs at home means no duplicated expenses — factor 2 fails, and factor 1 usually follows. A cheap room in a shared apartment you genuinely return to is often all it takes to keep the thread alive.
2. Extending in one city too long. The general industry rule of thumb is don't exceed about 12 months in one location for the same assignment without a genuine break (typically 6+ months away, though the underlying test is facts-and-circumstances, not a stopwatch).
3. Taking back-to-back assignments in the same metro. If all your work happens in one city, your tax home moves there. Your "travel" is now commuting.
4. Pocketing the difference tax-free with a relative. Paying token rent to family that you don't actually pay, or not paying fair market rent for a room you occupy, looks exactly like what it is.
5. No documentation. Lease, bank statements, utility bills, license address, returns to the area — keep the paper trail. If you're ever audited, the story that isn't documented didn't happen.
6. Assuming the agency's form makes it true. The agency asks whether you duplicate expenses because the rules make them; signing the form doesn't substitute for the facts.
What it's worth in dollars
Suppose you take home-area expenses of $800/month (room + storage) and receive $1,900/week in stipends. Those stipends, tax-free, are worth about $1,900. If your tax home fails and they're taxed as wages at an effective 25%, they're suddenly worth ~$1,425 — a loss of roughly $475/week, about $6,200 over a 13-week contract, plus potential penalties and interest on repayment. The $800/month room that keeps your tax home valid is the best ROI in travel nursing. Run your own numbers in the take-home calculator with and without stipends taxed.
When to get a professional
Everything here is the general framework, not advice for your specific facts. If your situation is anything other than a clean "home + duplicate expenses + assignments away" pattern — nomad plans, spouse's job relocation, long extensions, homeowners with empty houses — one hour with a CPA who knows travel healthcare pays for itself many times over.
Your tax home documentation checklist
If you claim tax-free stipends, you should be able to produce, in one folder, without a scramble:
1. Proof you pay to live at home: a lease or mortgage statement, or canceled rent checks to family at fair market rate — plus utility bills in your name. 2. Proof you return: anything dated that shows physical presence between assignments — toll records, fuel receipts near home, a gym membership log, medical appointments. 3. Ties that bind: driver's license, voter registration, car registration, bank accounts, all at the home address. 4. Duplicated expenses on assignment: your assignment housing lease or the agency housing arrangement, showing overlap with the home costs. 5. A simple travel log: assignment start/end dates, locations, weeks away.
Update the folder twice a year — the receipts you can find in January are the ones you kept in June. None of this needs to be fancy; it needs to exist. The difference between a documented tax home and an asserted one, over a three-year audit window, is routinely five figures.
FAQ
What is a tax home for travel nurses?
The general area of your regular work where you earn most of your income. Keep a valid one and stipends are tax-free; lose it and they're taxable wages.
How long can I stay in one location as a travel nurse?
The common guideline is under 12 months at one facility/location without a substantial break. The real test is whether the area became your tax home in fact — length is just strong evidence either way.
Can I use a family member's address as my tax home?
Only if it's real: you actually keep a room there, pay fair rent, and return between assignments. A free mailing address with no real living arrangement will not survive scrutiny.
Can I claim stipends if my spouse moves with me?
Yes, as long as the tax home itself stays real — the test looks at your duplicated expenses and ties, not at who travels with you. If your spouse keeps paying the mortgage or lease in your home area while you're on assignment together, your position is intact. If the family relocates to the assignment city and the home costs stop, factor two fails and the stipends become taxable.
Do I pay tax on stipend money I don't spend on rent?
No — with a valid tax home, stipends are tax-free per-diem allowances up to the GSA caps whether your rent is $600 or $1,600. You don't submit receipts, and banking the difference is legal and common. What the IRS cares about is the reality of the duplicated expenses, not what you did with the money.
