Receiving an audit notification from the Internal Revenue Service is a stressful event for any taxpayer, but travel nurses face distinct examination procedures. IRS auditors focus intently on whether you met the legal criteria to receive non-taxable lodging, meal, and travel stipends.
Understanding how an IRS audit proceeds, what documents examiners demand, and how to substantiate your claims under federal tax law can prevent catastrophic assessments.
The initial audit letter and Information Document Request
An IRS audit typically begins with an official notice by mail, often Form 4564 (Information Document Request). The letter specifies the tax year under examination and requests detailed documentation regarding your travel allowances, housing reimbursements, and employee business expenses.
Auditors know that travel staffing agencies pay large non-taxable stipends that do not appear in Box 1 of your Form W-2. The auditor goal is to verify whether those stipends qualify as tax-free reimbursements or whether they should be reclassified as taxable wages subject to income tax and 15.3 percent FICA.

Applying Revenue Ruling 73-529: The three-part test
During the audit, the examiner evaluates your tax home against the three criteria set forth in IRS Revenue Ruling 73-529:
First, whether you incur substantial, continuous living expenses at your permanent home that you duplicate while traveling. Second, whether you maintain historical business or employment connections in the vicinity of that home. Third, whether you have personal and family ties to that dwelling, including frequent physical presence.
If you satisfy all three factors, your tax home is legally confirmed. If you satisfy only two factors, the IRS may still accept your tax home depending on facts and circumstances. If you satisfy only one factor, you are classified as an itinerant worker, and all stipends become taxable.

Documents you must produce to win an audit
To successfully defend your tax home, you must provide organized documentation covering both your home and assignment locations:
Signed residential lease or mortgage statements for your permanent home, utility bills, property tax receipts, cancelled checks or electronic transfer receipts showing regular payments, signed travel nursing contracts and assignment confirmations, timecards, and receipts or lease contracts for temporary housing at every assignment location.
If you fail to produce documentation showing you duplicated living expenses, the IRS will issue a Notice of Deficiency assessing back taxes, interest, and substantial accuracy-related penalties.
You can verify the financial math of your travel contracts and model your exposure using our Contract Analyzer.
