Tax Home Rules for Physicians: When Travel and Lodging Are Deductible

2 days ago
19 min read

You signed a six month locums contract in Charlotte. You flew there twelve times. You rented an apartment three blocks from the hospital. You drove a rental car for half a year. The bill, all in, came to roughly $24,000 of travel and lodging costs.

In April, your return is sitting on your desk. The question is simple: how much of that $24,000 is deductible?

The honest answer is that it depends on the IRS tax home rules, and on a decision, you made before you ever got on the first flight. Travel and lodging deductibility for physicians turns on a contract clause most physicians never read carefully, and on whether the IRS considers your home city your tax home or whether they think you abandoned it. If you got the answer wrong, you cannot fix it now. The deductibility was locked in the day you signed.

This is the part of the tax code that catches physicians off guard. The travel deduction looks straightforward and then quietly hinges on a half dozen technical rules with names like "the one year rule" and "the three factor test." This guide is the working reference. Read it before your next contract, not after.

What the IRS Means by "Tax Home"

Ask ten physicians where their tax home is. Nine will name the city they live in. One will name the city where they work. Both groups are partly right and partly wrong.

Your tax home is not where you sleep at night. It is not where your family lives. It is not where you vote or where your mail arrives. The IRS defines it as the general area where you primarily conduct your work, regardless of where you maintain your family home. The whole city or general business area counts, not a specific building.

Why does this single definition matter so much? Because nearly every travel deduction available to a physician depends on whether you are traveling away from your tax home. If you are, ordinary and necessary travel costs become deductible business expenses. If you are not, those same costs are personal expenses, and personal expenses are deductible by no one.

A few refinements that catch physicians off guard:

More than one regular place of work? Your tax home is the one where you spend the most time and earn the most income. Total time, level of business activity, and significance of income are the three factors the IRS weighs.
No regular place of business because of how your work is structured? Your tax home may instead be the place where you regularly live.
No regular place of business and no place where you regularly live? You are an itinerant.

That last category is the trap, and it deserves its own sentence. Itinerant taxpayers carry their tax home with them wherever they work, which sounds like a perk until you read the next sentence in the regulations: they are never considered to be traveling away from home, and they can never deduct travel expenses.

A physician who strings together back to back locums assignments across multiple states with no real anchor city is a candidate for itinerant classification. The IRS does not look kindly on physicians claiming Tampa as their tax home when they spent three weeks of the year there.

When Are You "Traveling Away from Home"?

The next gate is a two part test that sounds soft but is not.

You are traveling away from home for tax purposes when both of the following are true:

Your duties require you to be away from the general area of your tax home substantially longer than an ordinary day's work, and
You need to sleep or rest to meet the demands of your work while away from home.

The sleep or rest rule is the one physicians underestimate. Napping in your car between cases does not count. Closing your eyes in a call room for forty minutes does not count. The trip has to be long enough that you need genuine sleep or rest before returning. Overnight assignments meet this easily. Brutal single day round trips usually do not, even if the day involved was 18 hours of work.

The "substantially longer than an ordinary day's work" piece matters too, because physicians work long days as a baseline. A 16 hour ED shift in your home city is your normal workday. It is not travel. The same 16 hours spent at a hospital in another state, with a hotel stay before returning, is travel. The duration is not what makes the difference. The destination and the overnight stay are.

The One Year Rule: Where Most Deductions Are Won or Lost

If you read only one section of this article, read this one. The temporary versus indefinite distinction is where the largest dollar amounts of physician travel deductions are made or lost. The rule is short. The application is anything but.

If your assignment away from your main place of work is temporary, your tax home does not change. You remain considered away from home for the entire assignment. Your travel expenses are deductible if they otherwise qualify. A temporary assignment in a single location is generally one that is realistically expected to last, and does in fact last, one year or less.

If your assignment is indefinite, the location of the assignment becomes your new tax home. Travel, lodging, and meal expenses at the new location are not deductible. An assignment in a single location is considered indefinite if it is realistically expected to last more than one year, regardless of whether it actually lasts that long.

The expectation at the time you accept the assignment controls the outcome. Not the actual duration. Not what you thought halfway through. The expectation on day one.

A few consequences follow from that:

A nine month contract that gets extended to 14 months still gets the deductions for the period during which the assignment was reasonably expected to end within a year. Once your expectation crosses the one year line, the deductions stop. Same physician, same hospital, different tax outcome.
An assignment that starts open ended or with no defined end date is treated as indefinite from day one. The vague handshake deal is the most expensive contract structure available to a locums physician.
A series of short assignments to the same location can be aggregated. Three nine-month contracts at the same hospital over three years can be treated as one continuous indefinite assignment, even though each individual contract was under a year.
A probationary work arrangement, where you keep the role if your work is satisfactory, is indefinite from the start. None of your costs during the probationary period are deductible.

The takeaway is that locums contract structure is not paperwork. It is tax planning. A defined 11 month contract with a clean end date is a fundamentally different document from a 12 month rolling contract that everyone assumes will be renewed, even when the daily work is identical.

The Three Factor Test for Physicians Without a Fixed Workplace

A different category of physician needs a different analysis. Full time locums physicians, physicians who travel constantly for medical legal work, and specialists who rotate across multiple regional sites often have no single regular place of business at all. For them, the IRS uses a three factor test to decide whether their primary residence qualifies as their tax home:

You perform part of your business in the area of your main home and use that home for lodging while doing business in the area.
You have living expenses at your main home that you duplicate because your business requires you to be away from that home.
You have not abandoned the area where your historical place of lodging and your claimed main home are located. Family lives there. You maintain community ties. You frequently return to the home for lodging.

Satisfy all three and your home is your tax home. Satisfy two and the outcome depends on the facts and circumstances. Satisfy only one and the IRS treats you as itinerant. No tax home, no deductible travel.

The third factor is the one that quietly destroys claims. The IRS wants to see that you have not abandoned the area, which means more than keeping a mailing address there. Several common patterns put the claim at risk:

Renting the home out for the duration of a long assignment, particularly if the rental income exceeds your duplicated living expenses.
Letting family occupy the home rent free without you contributing to its upkeep.
Spending so little time in your home city that the pattern itself raises the question of whether you have meaningfully maintained ties.
Carrying minimal personal expenses at the home. No utilities in your name. No homeowners insurance. No physical presence in the community.

Physicians who travel for work should treat their primary residence as evidence, not just as a place. Photographs of you at the home. Bills in your name. Time logged there. A real community footprint. These are the records that hold up under examination.

What Travel Expenses Are Deductible?

Once you have established a tax home and you are traveling away from it on a qualifying temporary assignment, the following come off the top of your taxable income:

Transportation between your tax home and the assignment location. Flights, train tickets, bus fares, and mileage if you drive your own vehicle.
Local transportation at the destination. Rental cars, taxis, rideshare, parking, and tolls.
Lodging for the duration of the assignment. Hotels, short term rentals, corporate housing, and a leased apartment near the assignment site are all deductible.
50% of non-entertainment business meals.
Baggage and shipping of professional supplies, instruments, or display materials.
Dry cleaning and laundry while on assignment.
Business calls and communications, including fax and other business related communication while traveling.

For meals, you have two options. Track actual costs and keep every receipt. Or use the federal per diem rate for meals and incidental expenses published by the General Services Administration. The per diem rate varies by location and time of year. Either method requires documentation of the time, place, and business purpose of your travel. The per diem method is administratively easier and tends to be the right choice for physicians who do not enjoy collecting receipts.

A few items physicians often assume are deductible but are not:

Travel expenses for a spouse or dependent who comes along. Generally not deductible unless the family member is your employee with a bona fide business purpose for the trip.
Costs of getting between your tax home and a family home that is not your tax home. If your tax home is in Charlotte but your family lives in Miami, the trips home to Miami are personal travel.
Lavish or extravagant meal expenses. The IRS does not draw a bright dollar line, but reasonable based on the facts and circumstances is the standard. A $400 steakhouse dinner with a colleague will draw scrutiny that a $40 meal will not.
Personal portions of a primarily business trip. Add three personal days onto a four day work trip and the lodging and meals for the personal days come out of the deduction.

The Days Off Rule

Here is one that catches physicians off guard, even physicians who have read everything else above.

You take a six month locums contract in Charlotte. Every other weekend you fly home to Miami to see your family. You assume the flights, the weekend meals, and the weekend lodging are all part of the assignment.

The IRS sees it differently. When you return to your tax home on days off during a temporary assignment, you are no longer considered away from home for those days. Meals and lodging in your home city are not deductible.

The flight itself is deductible, but with a cap. You can deduct the cost of travel between your temporary assignment location and your tax home, but only up to the amount it would have cost you to stay at the assignment location for those days. If you keep the hotel room or rental at the assignment location during your visit home, that cost remains deductible as well. The logic is that the IRS will allow you to do the cheaper of the two things, not both.

The rule rewards the physician who runs the math. If staying in Charlotte for the weekend would have cost $400 in lodging and meals, and the flights home cost $350, you take the $350. If the flights cost $600, you can deduct $400 and the rest is on you.

A Physician Scenario: Dr. Patel and Two Versions of the Same Contract

The cleanest way to see how the rules interact is to walk through one scenario twice, changing only the contract structure.

Dr. Patel is a physician. She lives in Miami in a home she has owned for seven years. Her husband and two kids live there with her. Her primary W-2 position is at a Miami area hospital where she works approximately 24 weeks per year.

She accepts a 1099 locums contract in Charlotte. The contract is for six months, with a defined start date in March and a defined end date in September. She rents a short term apartment three blocks from the Charlotte hospital, flies back to Miami every other weekend to see her family, and rents a car for her time in Charlotte.

Here is the tax home analysis:

Her tax home remains Miami. She spends most of her working time there and earns most of her income there.
The Charlotte assignment is temporary. Six months, well under the one year threshold, with a clear end date.
Her round trip flights between Miami and Charlotte at the start and end of the assignment are deductible business travel.
Her Charlotte apartment is deductible lodging for the full six months.
Her rental car in Charlotte is deductible.
50% of her business meals in Charlotte are deductible.
Her flights back to Miami on her off weekends are deductible up to the cost of staying in Charlotte for those weekends. If staying would have cost her $400 in lodging and meals and the flights cost her $350, the full $350 is deductible. Her meals in Miami during those visits are not deductible because Miami is her tax home.

Now change one thing. Dr. Patel accepts the same Charlotte assignment, but the contract is structured as an open-ended engagement. There is no defined end date. The hospital tells her in writing that they expect to want her for at least 18 months, with renewal options after that. Same physical work. Same Charlotte apartment. Same flight pattern. Same rental car.

Under the indefinite assignment rule, Charlotte becomes her new tax home from day one. The consequences:

Her Charlotte lodging is no longer deductible. It is personal housing at her new tax home.
Her Charlotte rental car is not deductible as travel. It is local commuting.
Her meals in Charlotte are not deductible.
Her flights between Miami and Charlotte are personal travel, not business travel.
The fact that she still owns and maintains her home in Miami does not save the deduction. The IRS does not require her to abandon Miami. It simply identifies Charlotte as her new tax home for the duration of the indefinite assignment.

Same physician. Same work. Same costs. Roughly $24,000 of deductions in version one. Zero in version two. The only thing that changed was a few sentences in the contract.

What Changed for W-2 Physicians

If you are working primarily as a W-2 employee, the entire analysis above has a different ending. The unreimbursed employee business expense deduction is gone.

The Tax Cuts and Jobs Act of 2017 suspended the deduction for unreimbursed employee business expenses through 2025. Before that suspension, W-2 employees could claim qualifying travel, lodging, and meal expenses as miscellaneous itemized deductions subject to a 2% adjusted gross income floor. The suspension removed that option for most W-2 employees.

The One Big Beautiful Bill Act made the suspension permanent. There is no scheduled return of the unreimbursed employee business expense deduction. For W-2 physicians who incur travel and lodging expenses tied to their employment, the federal tax treatment is unchanged regardless of whether the travel would otherwise qualify under the tax home rules.

The asymmetry this creates is striking. A 1099 locums physician traveling to a six month assignment in Charlotte can deduct flights, lodging, meals, and rental car costs as business expenses on Schedule C. A W-2 employed physician sent by the same hospital to the same Charlotte assignment, with the same out of

pocket expenses, cannot deduct any of it federally if the hospital does not reimburse the costs.

The planning move for W-2 physicians is therefore reimbursement, not deduction. The mechanism is an accountable plan, an employer established arrangement that meets three IRS requirements:

The expenses must have a business connection.
The employee must substantiate the expenses to the employer within a reasonable period.
The employee must return any excess reimbursement within a reasonable period.

When these conditions are met, reimbursements under the accountable plan are tax-free to the employee and deductible to the employer. The W-2 physician effectively gets the equivalent of a deduction, structured as a tax free reimbursement instead.

A few practical points:

Reimbursements outside an accountable plan, sometimes labeled as travel allowances or stipends, are taxable wages to the employee. They appear on the W-2 and are subject to income and payroll taxes. The physician is worse off than if the hospital paid nothing.
Hospitals and physician groups vary widely in whether they offer accountable plan reimbursements. Some have well structured plans. Others provide flat travel stipends that are taxable. The difference is meaningful.
For physicians negotiating new W-2 contracts, the structure of travel reimbursement is a real negotiation point. A higher salary with no reimbursement can be worse than a slightly lower salary with accountable plan reimbursements.
Some states still allow unreimbursed employee business expense deductions on the state return, even though the federal deduction is gone. State treatment varies and changes from year to year.

Common Tax Home Mistakes Physicians Make

A real tax home, real assignments, and decent receipts get most physicians to the right answer most of the time. The patterns below are where careful physicians still lose deductions. Each one is preventable with planning, and each one shows up regularly when reviewing physician returns.

Assuming All 1099 Travel Is Deductible

Independent contractor status opens the door to deducting business expenses. It does not exempt you from the tax home rules. A 1099 physician with no real tax home, or with an assignment structured as indefinite, faces the same restrictions as anyone else. The W-2 versus 1099 distinction changes the mechanism of the deduction. It does not change the underlying eligibility.

Letting the Primary Residence Lapse

Physicians on long assignments sometimes treat their primary residence as a placeholder. They return occasionally. They rent it out. They remove personal belongings. They transfer the utilities to someone else's name. Each step weakens the claim that they still have a tax home there. By the time the third factor is examined, there is not much left to point to.

Ignoring the One Year Expectation Rule

The rule is based on what you reasonably expected at the time you accepted the assignment, not what eventually happened. Physicians who sign open ended contracts assuming they can claim travel deductions until some unstated future end date are often surprised when the IRS treats the assignment as indefinite from day one. Vague language in a contract is not the physician's friend.

Mixing Personal and Business Travel Without Documentation

A primarily business trip can include some personal time. The personal portion is not deductible. Without contemporaneous records showing the business purpose of each day, the IRS can disallow the entire trip, not just the personal portion. The burden of proof is on the physician, not the agent.

Treating Commuting as Travel

Even with a clearly established tax home, daily commuting between your residence and your regular place of business is not deductible. The tax home rules carve out travel to genuinely separate work locations. They do not carve out the daily drive to your hospital, no matter how long it is.

Aggregating Short Assignments Without Realizing the Risk

A series of three month assignments to the same city, repeated over multiple years, can be aggregated by the IRS into a single indefinite assignment. Each individual contract being under a year does not protect the deductions if the overall pattern shows a long term work relationship. The IRS looks at the substance of the arrangement, not just the form of each contract.

Recordkeeping Standards for Physician Travel

Travel deductions are one of the more frequently examined areas on physician tax returns. Strong recordkeeping is not optional. It is the difference between an examination that resolves in a single phone call and one that drags on for months.

The records you keep at the time of the expense are dramatically easier to assemble than the records you try to reconstruct two years later during an examination. Physicians who reconstruct from credit card statements alone, without contemporaneous calendars and contracts, lose deductions they could have substantiated easily at the time.

The IRS standard for travel substantiation requires documentation of:

The amount of each expense
The time and place of the travel
The business purpose of the travel
The business relationship to any other person involved. For meals, this means identifying the person and the business purpose of the meal.

For physician travel, practical recordkeeping looks like:

Copies of every locums contract or assignment letter, with start and end dates clearly documented
Receipts for all lodging expenses, regardless of dollar amount
Receipts for meals over $75, plus per diem documentation if using the standard meal allowance method
A mileage log if claiming the standard mileage rate for vehicle use
Flight confirmations, hotel folios, and rental car contracts
Calendar entries showing the business purpose of each day during a trip
Bank or credit card statements showing the timing of expenses

Publication 463 (2025), Travel, Gift, and Car Expenses | Internal Revenue Service

Digital recordkeeping tools have made this far easier than it used to be. Several apps will photograph and categorize receipts at the time of the expense, pair them with calendar entries, and export the result. The key is contemporaneous documentation, meaning records created at or near the time of the expense, not assembled at year end. A receipt photographed the day it was issued is worth ten receipts dug out of a shoebox in April.

Where Tax Planning Comes In

Notice what the rules above have in common. The contract structure controls. The expected duration controls. The residency pattern controls. The reimbursement arrangement controls.

All of those are set before the assignment begins. By the time tax season arrives, the deductibility is already decided. There is no version of this where you save the return by being clever in April.

This is why year round tax planning has more practical value for traveling physicians than tax filing alone. A locums contract reviewed before it is signed can often be restructured to preserve deductions. The same contract reviewed in April after a year of work cannot. The cheapest hour of professional time you will spend all year is the hour spent reading a contract before you sign it.

At Doc Wealth, your tax team can:

Review locums contracts for tax home implications before you sign, including contract length, renewal language, and reimbursement structure
Structure your residency, work pattern, and primary home ties to support a clear tax home
Build a recordkeeping approach that will hold up under examination
Plan around the W-2 versus 1099 distinction when you have a choice between employment structures

For physicians who take more than one out of area assignment in a typical year, the cumulative tax impact of getting these decisions right is substantial. We have seen multi-year deduction totals in the high five figures preserved or destroyed by contract language alone.

The Bottom Line

Two questions decide whether your physician travel is deductible:

Where is your tax home?
Is the current assignment temporary or indefinite?

If your tax home is well established, and your assignment is realistically expected to last one year or less, your travel, lodging, rental car costs, and a portion of your meals are deductible business expenses on the proper schedule. If the assignment is indefinite, or if you have no genuine tax home to travel away from, the deductions do not apply.

For 1099 physicians, the deduction mechanism is direct, recorded on Schedule C as part of your self-employment income calculation.
For W-2 physicians, the federal unreimbursed employee business expense deduction is no longer available, which makes accountable plan reimbursement from the employer the only practical way to recover the cost of business travel without tax.

The decisions that determine the outcome are made before the assignment begins. Reviewing a contract before you sign is dramatically more valuable than reviewing it on a return after the fact.

If you are taking locums or moonlighting assignments this year, your tax team at Doc Wealth can review the contract before you sign. Prompt, dependable communication.

FAQ

What is a physician's tax home for IRS purposes?

A physician's tax home is the general area where they primarily conduct their work, regardless of where they maintain their family home. It includes the entire city or general business area where the main place of work is located. If a physician has more than one regular place of work, the tax home is the location where they spend the most time and earn the most income.

Can a 1099 locums physician deduct travel and lodging expenses?

A 1099 locums physician can deduct travel, lodging, rental car costs, and 50% of business meals when traveling away from a clearly established tax home on a temporary assignment realistically expected to last one year or less. The deductions are claimed on Schedule C as part of the self-employment income calculation. If the assignment is indefinite or the physician has no genuine tax home, the deductions do not apply.

Can W-2 physicians deduct unreimbursed travel expenses?

Federal law no longer allows W-2 physicians to deduct unreimbursed employee business expenses. The Tax Cuts and Jobs Act suspended the deduction in 2017, and the One Big Beautiful Bill Act made the suspension permanent. The practical alternative for W-2 physicians is to have the employer reimburse business travel through a qualifying accountable plan, which keeps the reimbursement tax free to the employee.

How long can a temporary assignment last and still be deductible?

A temporary assignment in a single location is generally one that is realistically expected to last, and does in fact last, one year or less. If the assignment is expected to last more than one year at the time it is accepted, it is considered indefinite from day one, and travel expenses at that location are not deductible. The expectation at the start of the assignment controls the outcome, not the actual duration.

What happens if a temporary assignment gets extended past one year?

The deduction is allowed for the period during which the assignment was realistically expected to end within a year. Once the expectation crosses the one year line, the deductions stop, even if no other facts have changed. A nine month contract extended to 14 months would generally allow deductions for the first nine months, with deductions ending at the point the extension creates an expectation of more than 12 months total.

Are flights home to see family deductible during a locums assignment?

Flights between a temporary assignment location and the physician's tax home are deductible up to the amount it would have cost to stay at the assignment location for those days. Meals and lodging in the home city during the visit are not deductible because the physician is not considered away from home while at the tax home. If the assignment location lodging is retained during the visit, that cost remains deductible.

What records do physicians need to keep for travel deductions?

The IRS requires documentation of the amount of each expense, the time and place of the travel, and the business purpose. Practical records include copies of every locums contract with start and end dates, receipts for all lodging expenses, receipts for meals over $75 (or per diem documentation), a mileage log if claiming the standard mileage rate, flight and hotel confirmations, and calendar entries showing the business purpose of each day. Records should be created at or near the time of the expense, not reconstructed at year end.
