A travel nurse's tax return looks unusual to a computer: modest W-2 wages next to tens of thousands of dollars in untaxed stipends, a home address in one state, income in three others. None of that is wrong — but it is visible. Audit readiness for a traveler isn't about being lucky; it's about holding the specific pieces of paper the IRS asks for, filed the year they happened, not reconstructed three years later in a panic.
IRS selection is largely automated scoring plus targeted programs. Several traveler-specific patterns raise the score: a low taxable wage relative to your specialty (agencies that suppress the hourly rate to inflate tax-free stipends create returns that look like a $38,000-a-year nurse living a $90,000 life), stipends that exceed federal per-diem rates for the area, multi-state filings with residency ambiguity, and 1099 side income with aggressive deductions. Add that tax-home abuse by mobile workers is a known compliance area, and a traveler's return simply gets more scrutiny per dollar than a staff nurse's. This is not a reason to avoid stipends — they're legal and the entire economic point of traveling. It's a reason to keep records like you expect to be asked.
Tax-free stipends rest entirely on you having a tax home — a main place of abode whose expenses you continue paying while you work away from it. Lose the tax home, and every dollar of housing and meal stipend you received becomes taxable income, retroactively, plus penalties and interest. The rules are covered in depth in our tax home guide and tax home rules explainer; for audit purposes what matters is the evidence chain:
| What the auditor asks | Winning evidence | Losing answer |
|---|---|---|
| Do you maintain a home you pay for? | Lease/mortgage in your name, 12 months of rent or mortgage payments, utilities | "I stay at my parents' place free between contracts" |
| Are you duplicating expenses on assignment? | Rent receipts at BOTH locations for the same months | Stipend received while subletting your home out |
| Do you return to it? | Flight/gas receipts home between contracts, per-diem shifts worked near home | No trips home in 18 months |
| Is it more than a mail drop? | Driver's license, voter registration, car registration, bank, PCP/dentist all there | Address is a relative's house you visit twice a year |
| Did you abandon it by staying away? | Contracts under 12 months in one metro, then moving on | Back-to-back renewals in one city for years ("the 12-month rule") |
Beyond the tax home, the recurring flags are: stipends above the federal per-diem tables for your assignment ZIP (compare your package against the current rates — overages should be small and explainable); missing state returns (California and New York in particular data-match aggressively — see our California guide); mismatches between agency-reported W-2s and what you filed, common after mid-year agency switches; and Schedule C deductions against 1099 per-diem income that look personal (100% phone, 100% car). If you file quarterly on side income, our 1099 estimated taxes guide covers keeping that clean.
Keep one cloud folder per tax year with five subfolders. Contracts: every signed contract and pay-package breakdown showing the taxable/stipend split. Tax home: lease or mortgage statements, 12 months of payment proof, utilities, and a January photo of your license/registration/voter card. Duplicated housing: assignment leases, Furnished Finder/landlord receipts, hotel folios. Travel: receipts for trips to and from assignments and trips home. Income: final pay stub from each agency, all W-2s/1099s. Ten minutes at each month's end to drop documents in; that's the entire system. Keep each year for at least three years after filing (the standard assessment window) and six if you ever under-report substantially — storage is free, reconstruction is not.
First, read what kind it is. A CP2000 is not an audit — it's a computer saying your return doesn't match documents it received (usually a missed W-2 or 1099); respond by the deadline with agreement or documentation. A correspondence audit asks you to mail evidence for specific items — this is where the folder above pays for itself. A field or office audit for a typical traveler is rare. Respond by every deadline, send copies never originals, and answer only what is asked. If the issue is your tax home or more than one year is open, hire a preparer who works with travelers before responding — representation at that point costs hundreds and can save tens of thousands. And never ignore the letter: silence converts proposed changes into assessed tax.
