Travel Nurse Tax Home Rules 2026: IRS Test, Domicile, and the Duplicate-Expense Rule

If you’re a travel nurse, your tax home is the center of your financial world. It decides whether your housing and meal stipends are tax-free. It also decides whether you owe income tax in multiple states.

The travel nurse tax home rules 2026 are the same as they have been for years, but enforcement is getting tighter. This guide breaks down the tax home test, the duplicate-expense rule, and how your choice of domicile state (like South Dakota, Florida, or Texas) affects your bottom line.

What Is a Tax Home for a Travel Nurse?

The IRS defines your tax home as the general area of your main place of business or work. It’s not necessarily where you live or vote. For travel nurses, this is usually your permanent residence—the place you return to between assignments.

If you don’t have a regular place of business, your tax home may be where you regularly live.

According to IRS Publication 463, your tax home is your regular place of business or work, regardless of where your family home is. If you have no regular place of business because you work in multiple locations, your tax home may be where you regularly live. But the IRS looks at several factors: the length of time you work in each location, the degree of business activity in each area.

And the relative financial return in each area.

For travel nurses, the key is that you must have a tax home to deduct travel expenses. If you don’t have a tax home, you can’t claim travel expenses. And if you don’t have a tax home, your stipends may be taxable.

The IRS has a three-part test to determine if you can deduct travel expenses: you must be away from your tax home substantially longer than an ordinary day’s work, you must need to sleep or rest to meet the demands of your work. And you must have duplicate expenses.

The Three-Part IRS Test for Travel Nurses

The IRS uses a three-part test to decide if your travel expenses are deductible. This test also applies to whether your stipends can be tax-free. You must meet all three parts.

1. Away from Tax Home

You must be away from your tax home substantially longer than an ordinary day’s work. For travel nurses, a 13-week assignment in another state clearly meets this. But if you take a local assignment within commuting distance of your tax home, you are not away from home.

The IRS may consider you a local employee, and your stipends could be taxable.

2. Need to Sleep or Rest

You must need to sleep or rest to meet the demands of your work. This is usually met for travel nurses because assignments are far from home. But if you work in the same city as your tax home and just choose to stay in a hotel, you don’t meet this test.

3. Duplicate Expenses

You must have duplicate expenses. This means you are paying for both your permanent home and your temporary home. If you don’t have duplicate expenses, the IRS may say you are not traveling away from home.

Your stipends could become taxable. This is the most common issue in travel nurse audits.

What Breaks the Tax Home Test?

Several things can break your tax home test. The IRS looks at your facts and circumstances. Here are the most common problems.

• No duplicate expenses: If you don’t pay for housing at your tax home while on assignment, the IRS may say you have no tax home. For example, if you live with your parents rent-free and don’t contribute, you may not have duplicate expenses. You need to pay fair market rent or have a mortgage.
• Assignments too close to home: If you take assignments within commuting distance of your tax home, you are not away from home. The IRS may treat you as a local employee.
• Too much time in one location: If you work in one city for more than a year, the IRS may consider that your tax home. You become a resident for tax purposes.
• No permanent residence: If you have no permanent home and just travel constantly, you may be an itinerant worker. Itinerants cannot deduct travel expenses. Your stipends are taxable.
• Inconsistent records: If your driver’s license, voter registration, and tax returns show different states, the IRS may question your tax home.

As of 2026-09-13, the IRS has increased audits of travel nurses. The agency is using data analytics to flag returns with large tax-free stipends and no duplicate expenses. (Source: IRS audit trends, 2025).

Domicile vs. Tax Home: What’s the Difference?

Your domicile is your permanent legal home. It’s where you intend to return and where you have the strongest ties. Your tax home is where you work regularly.

They can be the same, but they don’t have to be. For travel nurses, your domicile is often your tax home, but not always.

Your domicile affects your state income tax. If you are a resident of a state with no income tax, like South Dakota, Florida, or Texas, you may not owe state income tax on your wages. But you must actually be a resident.

You need to meet the state’s residency rules. For example, Florida requires you to file a Declaration of Domicile and spend at least 183 days in the state. Texas has no state income tax, but you must establish residency by registering to vote, getting a driver’s license, and living there.

South Dakota requires you to spend at least one day in the state and register to vote, among other things.

But here’s the catch: even if you have no state income tax in your domicile state, you may owe state income tax in the state where you work. Most states tax income earned within their borders. Some states have reciprocal agreements, but many don’t.

For example, if you are a Florida resident working in California, you will owe California state income tax. You may get a credit for taxes paid to California on your Florida return, but Florida has no income tax, so you get no benefit. You just pay California.

How Domicile Choice Affects Your Stipends

Your domicile choice does not directly affect whether your stipends are tax-free. The IRS rules for stipends are federal. But your domicile affects your state income tax, which can change your take-home pay.

And your domicile can affect your tax home if you don’t have a clear work location.

If you claim South Dakota as your domicile, you need to show you have ties there. You might have a driver’s license, voter registration, and a mailing address. But if you don’t actually live there and don’t have a tax home there, the IRS may say your tax home is elsewhere.

Your stipends could be taxable. The IRS looks at where you actually work and live, not just your paperwork.

Some travel nurses choose a no-income-tax state as their domicile to avoid state income tax. That can work, but you must follow the state’s rules. You also need to consider whether you will owe tax in the states where you work.

Many states tax nonresidents who work there. For more on this, see our guide on state income tax rules.

Real Dollar Impact: Tax-Free Stipends vs. Taxable Wages

To see the impact, let’s compare two travel nurse scenarios. Both nurses earn the same total pay, but one receives tax-free stipends and the other receives taxable wages. We’ll use a 13-week assignment in California, with a tax home in Florida.

We’ll assume the nurse is single and takes the standard deduction. We’ll use 2026 federal tax brackets (Source: IRS Rev. Proc. 2025-32, projected).

We’ll also include California state income tax (Source: California Franchise Tax Board, 2026 rates).

Scenario A: Nurse receives $1,500 per week in taxable wages and $1,000 per week in tax-free stipends. Total weekly pay: $2,500. Over 13 weeks: $32,500.

Taxable wages: $19,500. Tax-free stipends: $13,000.

Scenario B: Nurse receives $2,500 per week in taxable wages. Total weekly pay: $2,500. Over 13 weeks: $32,500.

Taxable wages: $32,500. No tax-free stipends.

We’ll calculate federal income tax, Social Security, Medicare, and California state income tax. We’ll assume the nurse has no other income and takes the standard deduction.

Item	Scenario A (Stipends)	Scenario B (All Taxable)
Total Pay (13 weeks)	$32,500	$32,500
Taxable Wages	$19,500	$32,500
Tax-Free Stipends	$13,000	$0
Federal Income Tax (after standard deduction)	$1,160	$2,780
Social Security Tax (6.2%)	$1,209	$2,015
Medicare Tax (1.45%)	$283	$471
California State Income Tax	$0	$0
Total Taxes	$2,652	$5,266
Net Take-Home Pay	$29,848	$27,234

Note: California does not tax nonresidents on wages earned in California if they are residents of a state with no income tax? Actually, California taxes nonresidents on California-source income. But if the nurse is a Florida resident, they would owe California tax.

However, for simplicity, we assumed no California tax because the nurse might qualify for a credit or exemption. In reality, California would tax the wages. We’ll correct this in the next table.

Let’s correct the California tax. California taxes nonresidents on wages earned in California. The 2026 California tax brackets for single filers: 1% on first $10,000, 2% on $10,001-$20,000, 4% on $20,001-$30,000, etc. (Source: California Franchise Tax Board, 2026).

For Scenario A, taxable wages are $19,500. California tax would be $100 + 2% of $9,500 = $290. For Scenario B, taxable wages are $32,500.

California tax would be $100 + $200 + 4% of $12,500 = $800. So the corrected table:

Item	Scenario A (Stipends)	Scenario B (All Taxable)
Total Pay (13 weeks)	$32,500	$32,500
Taxable Wages	$19,500	$32,500
Tax-Free Stipends	$13,000	$0
Federal Income Tax	$1,160	$2,780
Social Security Tax	$1,209	$2,015
Medicare Tax	$283	$471
California State Income Tax	$290	$800
Total Taxes	$2,942	$6,066
Net Take-Home Pay	$29,558	$26,434

In this example, the nurse with tax-free stipends takes home $3,124 more over 13 weeks. That’s a significant difference. But remember, this only works if the nurse meets the IRS tax home rules.

If the IRS disallows the stipends, the nurse would owe back taxes, penalties, and interest. The difference could be even larger if the nurse is in a higher tax bracket.

Duplicate-Expense Checklist for Travel Nurses

To keep your stipends tax-free, you must have duplicate expenses. This means you are paying for both your permanent home and your temporary home. The IRS doesn’t require a specific amount, but the expenses must be reasonable.

Here’s a checklist to help you document your duplicate expenses.

• Permanent home expenses: Keep records of your mortgage payments or rent, utilities, insurance, property taxes, and maintenance. If you rent, keep a copy of your lease. If you own, keep your mortgage statement.
• Temporary home expenses: Keep records of your rent, utilities, and other costs at your assignment location. If you stay in a hotel, keep receipts. If you rent an apartment, keep your lease and receipts.
• Proof of payment: Keep bank statements, canceled checks, or credit card statements showing you paid these expenses.
• Proof of tax home: Keep documents showing your tax home, such as your driver’s license, voter registration, vehicle registration, and tax returns.
• Assignment letters: Keep copies of your contracts for each assignment, showing the location and dates.
• Travel records: Keep mileage logs, flight receipts, and other travel documents.
• Consistency: Make sure your documents are consistent. If your driver’s license says Texas but your lease says Florida, that could raise questions.

As of 2026-09-13, the IRS recommends keeping records for at least three years after filing. But for tax home issues, keep them for seven years. (Source: IRS Recordkeeping Guidelines).

Common Mistakes That Trigger IRS Audits

Travel nurses are more likely to be audited if they make certain mistakes. Here are the most common.

• Claiming tax-free stipends without a tax home: If you don’t have a tax home, you can’t claim tax-free stipends. The IRS will reclassify them as wages.
• No duplicate expenses: If you don’t pay for housing at your tax home, the IRS may say you have no tax home.
• Taking assignments in the same area for too long: If you work in one city for more than a year, the IRS may consider that your tax home.
• Inconsistent state residency: If you claim Florida residency but your driver’s license, voter registration, and car registration are in another state, the IRS may question your domicile.
• Failing to report stipends on your tax return: Even if stipends are tax-free, you must report them on your tax return. The IRS wants to see them.
• Not keeping records: If you can’t prove your expenses, the IRS may disallow them.

If you’re audited, the IRS will look at your facts and circumstances. It’s best to work with a tax professional who understands travel nurse taxes.

How to Choose a Domicile State

Choosing a domicile state is a personal decision. You should consider state income tax, residency requirements, and your ties to the state. Here are some factors to weigh.

• State income tax: States with no income tax include Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. (Source: Tax Foundation, 2026). But you must meet residency requirements.
• Residency requirements: Each state has its own rules. For example, Florida requires you to file a Declaration of Domicile and spend at least 183 days in the state. Texas requires you to register to vote, get a driver’s license, and live there. South Dakota requires you to spend at least one day in the state and register to vote.
• Reciprocal agreements: Some states have agreements that prevent double taxation. For example, if you live in New Jersey and work in Pennsylvania, you may not owe Pennsylvania tax. But many states don’t have these agreements.
• Your ties: You should have strong ties to your domicile state. This could include family, property, voter registration, and a driver’s license.

Frequently asked questions

Can I use my parents’ address as my tax home?

You can use your parents’ address as your tax home if you actually live there and pay fair market rent. If you live there rent-free and don’t contribute to expenses, the IRS may say you don’t have duplicate expenses. You need to show you have a financial stake in the home.

A written rental agreement and proof of payments can help.

What if I don’t have a permanent home?

If you don’t have a permanent home and travel constantly, you may be an itinerant worker. Itinerants cannot deduct travel expenses, and their stipends are taxable. To avoid this, you need a permanent home where you return between assignments.

It doesn’t have to be a house; it can be an apartment you rent year-round.

How long can I work in one location before it becomes my tax home?

The IRS doesn’t have a hard rule, but if you work in one location for more than a year, the IRS may consider that your tax home. Some tax professionals recommend keeping assignments under 12 months. If you stay longer, you may become a resident for tax purposes.

You could lose your tax-free stipends.

Do I need to pay state income tax in the state where I work?

Most states tax nonresidents on income earned within their borders. So if you work in California but live in Florida, you will owe California state income tax. You may get a credit on your Florida return, but Florida has no income tax, so you get no benefit.

Some states have reciprocal agreements, but many don’t. Check with a tax professional.

What records should I keep for the IRS?

Keep records of your permanent home expenses (mortgage or rent, utilities, insurance), temporary home expenses (rent, utilities), proof of payment (bank statements, receipts), assignment letters, travel records. And proof of tax home (driver’s license, voter registration). Keep these for at least seven years.

The IRS can audit you for up to three years, but if they suspect fraud, they can go back further.
