Tax Home Audits for Travel Nurses: What the IRS Actually Looks For

The tax home is the single most scrutinized issue on a travel nurse’s tax return. Get it wrong and you don’t just lose the tax break on your stipends — you potentially owe back taxes, penalties, and interest on years of returns.

Here’s what auditors actually look at.

What the IRS Is Trying to Determine

The core question: Do you have a genuine tax home that you’re duplicating expenses to leave, or are you an itinerant worker with no fixed home?

If the IRS decides you’re itinerant — that you have no tax home — all your stipends become taxable income. This is the audit outcome travel nurses fear most.

To defend your tax home, you need to show three things:

1. You incur substantial, ongoing expenses at your primary residence
2. You return to that residence regularly
3. You have economic reasons for maintaining it (income history, job connections)

The Evidence Auditors Request

Financial records:

• Rent receipts, mortgage statements, or lease agreements for your permanent address
• Utility bills showing regular usage (not just a forwarding address)
• Property tax records if you own
• Evidence you continued paying these expenses during assignments

Income history:

• Prior tax returns showing work history in your tax home state
• Evidence you earned income there before going travel
• Nursing license registered in your tax home state

Return frequency:

• Dates and evidence you returned home between contracts
• Hotel receipts, gas receipts, flight records during contract gaps
• Any weeks you actually worked at your home hospital (per diem work)

Intent to return:

• License renewal in your home state
• Voter registration at home address
• Car registration and insurance at home address
• Bank account with home address

The Three-Pronged IRS Test

IRS Publication 463 and related case law uses a three-prong test:

Prong 1: Do you work regularly in the area of your tax home? This doesn’t mean you work there currently — it means your employment history and professional connections are there. A license in the state, prior hospital employment, and per diem work helps.

Prong 2: Are you required to duplicate living expenses? You must actually be spending money to maintain your home while also paying for housing on assignment. “My parents let me stay there for free” doesn’t qualify as a duplicated expense.

Prong 3: Do you have not abandoned your tax home? You must return regularly and have ongoing ties — friends, family, professional connections, civic involvement.

Missing any prong weakens the claim. Missing two creates serious audit risk.

Common Reasons Tax Homes Fail Audit

No income history at home. Moving to a new state, calling it your tax home, then immediately starting travel assignments is a major red flag. The IRS expects a demonstrated work history.

Free housing from family. If you’re “maintaining a permanent residence” at your parents’ house rent-free, you’re not duplicating expenses. No expense duplication = no tax home.

Multi-year gap from home state. If you haven’t worked in your tax home state in 3+ years, haven’t been licensed there recently, and don’t return regularly — the home looks abandoned.

Assignment duration creep. Travel contracts are supposed to be temporary. If you’ve been at the same hospital for 2+ years on rolling 13-week contracts, the IRS may argue you’ve established a new tax home at the assignment location.

Weak or no documentation. Assertions without receipts, bank statements, or other records to back them up are not enough.

What “Regular Return” Actually Means

There’s no bright-line rule on frequency, but courts have looked at whether a nurse returns home between contracts. Returning once or twice a year is thin. Returning between every contract — or even most contracts — is much more defensible.

Save all records: flight itineraries, hotel receipts, credit card statements showing purchases at home, photos with family. If you’re ever audited, this is the paper trail that wins.

If Your Tax Home Is Weak

Don’t wait for an audit to address this. Options:

• Take per diem shifts at your home hospital between travel contracts to establish or re-establish income history
• Pay real rent (even to family) and document it with a lease and bank transfers
• Update all your registrations: voter, car, professional license
• Work with a travel nurse CPA to review your situation annually

The best audit defense is a tax home that would withstand scrutiny before you’re asked. Document everything from day one, return home regularly, and maintain genuine financial ties to your home location. If your situation is borderline, consult a CPA who specializes in travel nurse taxes before the IRS asks.
