Physician Business Travel Deductions

Continuing Medical Education (CME) is a professional requirement for maintaining your medical license, and travel to CME conferences is one of the most common—and most frequently mishandled—physician travel deductions. The rules differ significantly depending on whether you're self-employed (1099) or a W-2 employee.

For Self-Employed / 1099 Physicians

If you're a 1099 independent contractor (including locum physicians and practice owners), CME conference travel is deductible on Schedule C as an ordinary and necessary business expense. Here's what you can deduct:

For W-2 Employed Physicians

Under the Tax Cuts and Jobs Act (TCJA), W-2 employees cannot deduct unreimbursed business expenses on their personal tax returns through 2025. This means if your employer doesn't reimburse your conference travel, you're paying out of pocket with after-tax dollars.

The solution? Ask your employer about their accountable plan. Under an accountable plan, your employer can reimburse your CME travel expenses tax-free to you and deduct them as a business expense. Many hospitals and medical groups already have accountable plans—you just need to submit your expenses properly.

The "Primary Purpose" Test for Mixed Trips

When you combine business travel with personal vacation, the deductibility of your transportation costs (airfare, driving) depends on the primary purpose of the trip. The IRS looks at:

• Days spent on business vs. personal activities — If more than 50% of the total days are business days, the primary purpose is likely business
• The reason you chose the destination — Did you pick the conference because it was in Hawaii, or did you extend your stay because the conference happened to be there?
• Travel days count as business days — The day you fly to and from the conference count as business days
• Weekends sandwiched between business days count — If you have business on Friday and Monday, Saturday and Sunday are business days

The explosion of virtual CME since 2020 has created new tax questions for physicians. If a course is available online, can you still deduct travel to attend it in person? The answer is nuanced and depends on the specific circumstances.

When Travel for Virtual-Available CME IS Deductible

• Hybrid conferences with unique in-person components — If the conference offers hands-on workshops, cadaver labs, simulation training, or networking events only available in person, travel to attend these components is deductible
• Required in-person attendance — Some board certifications, fellowship programs, or hospital credentialing require in-person attendance at specific courses
• Conferences where networking is the primary value — If your business purpose for attending is to network with colleagues, recruit staff, or build referral relationships, the in-person component has independent value beyond the educational content

When Travel for Virtual-Available CME Is NOT Deductible

• Identical content available online — If you can get the exact same CME credits by watching a webinar from your living room, the IRS may argue the travel was for personal convenience, not business necessity
• Choosing a destination because of the location — Attending an online course "in person" at a resort is a vacation, not a business trip
• No incremental business value from attendance — If the in-person version offers nothing beyond what the virtual version provides, the travel component is personal

For locum tenens physicians, travel deductions are typically the single largest category of deductible expenses. But the line between deductible "business travel" and non-deductible "commuting" is one that the IRS enforces aggressively. Understanding this distinction can mean the difference between claiming $40,000+ in deductions and claiming nothing.

Deductible Business Travel

Travel from your established tax home to a temporary work location (assignment expected to last one year or less) is deductible business travel. This includes:

• Airfare or driving expenses to reach the assignment location
• Lodging at the assignment location (entire duration)
• Meals while away from your tax home (per diem or actual)
• Rental car or local transportation
• Periodic return trips to your tax home

Non-Deductible Commuting

Travel from your home to your regular place of work is commuting—always non-deductible. For locum physicians, this becomes an issue when:

• You don't have an established tax home (itinerant worker—every work location is your "regular" workplace)
• An assignment becomes indefinite (expected to last more than one year)
• You take a permanent position at a facility where you previously worked as a locum

First and Last Day Rules

Travel days (the day you depart for an assignment and the day you return home) are considered business days. You can deduct meals and incidentals for these days, even if you don't work clinical hours. Similarly, if you arrive the day before your assignment starts or leave the day after it ends, that travel day is generally deductible.

A Dollar-by-Dollar Example: 13-Week EM Locum

Dr. Rodriguez, an emergency medicine physician based in Austin, TX (his tax home), takes a 13-week locum assignment in Portland, OR. Here's a breakdown of his deductible travel expenses:

When deducting meals and incidental expenses (M&IE) during business travel, you have two options: the actual expense method (deduct exactly what you spent, with receipts) or the per diem method (use the federal per diem rate for the location, no meal receipts needed). For most locum physicians, the per diem method is both simpler and more lucrative.

How the Per Diem Method Works

The General Services Administration (GSA) sets per diem rates for every county in the United States. These rates include two components: lodging (which self-employed individuals cannot use for per diem—you must use actual receipts for lodging) and Meals & Incidental Expenses (M&IE), which is what you can claim without receipts.

For 2025, the standard M&IE rate for most U.S. locations is $59 per day. High-cost cities have higher rates—up to $79 per day for cities like New York, San Francisco, Washington D.C., and Boston.

Per Diem Rates for Common Physician Travel Destinations (2025)

First and Last Day Rule for Per Diem

On the first and last days of any trip, you can only claim 75% of the full per diem rate. All days in between are at 100%. For a 91-day assignment:

• Day 1: 75% x $79 = $59.25
• Days 2–90: 100% x $79 = $79.00 each ($7,031 total)
• Day 91: 75% x $79 = $59.25
• Total per diem claim: $7,149.50

The general rule is simple: your spouse's travel expenses are not deductible unless your spouse has a bona fide business purpose for being on the trip. "Keeping you company" or "attending the spouse program at the conference" does not qualify. However, there are legitimate strategies that can make spouse travel deductible.

Strategy 1: Employ Your Spouse Through Your S-Corp

If you operate through an S-Corporation (which many locum physicians do for self-employment tax savings), you can hire your spouse as a legitimate employee. Common roles include:

• Office administrator / bookkeeper
• Credentialing coordinator
• Marketing and social media manager
• Research assistant

When your spouse-employee attends a conference to network, take notes on behalf of the practice, coordinate with vendors, or attend business sessions relevant to their role, their travel becomes a deductible business expense of the S-Corp.

Strategy 2: The Shared Room Approach

Even when your spouse's travel is not deductible, bringing them along may not cost you any deductions. Here's why: a hotel room that costs $250/night for one person often costs the same $250/night for two people (or maybe $275 with a nominal charge for the second guest). You can deduct the amount you would have paid for the room if you were traveling alone—which is the full single-occupancy rate.

Similarly, your airfare is fully deductible regardless of whether your spouse is on the same flight. The only truly non-deductible expenses are those that are solely for your spouse: their airfare, their meals, their activities.

Dollar Example: Conference With Spouse

International medical conferences are deductible, but the IRS imposes additional requirements beyond those for domestic travel. The rules differ based on whether the conference is held in North America, outside North America, or on a cruise ship.

Conferences in North America (Including Canada and Mexico)

Conferences in the United States, Canada, Mexico, and U.S. territories (Puerto Rico, U.S. Virgin Islands, etc.) follow the same rules as domestic conferences. No additional restrictions apply. The "primary purpose" test and mixed-trip rules described in Section 1 govern deductibility.

Conferences Outside North America

For conferences held outside North America (Europe, Asia, Africa, South America, etc.), you must establish that it was as reasonable to hold the meeting outside North America as within it. The IRS considers:

• The purpose of the meeting and its activities
• The purpose and activities of the sponsoring organization
• The residences of the active members and likely attendees
• Places where prior meetings have been held

Major international medical society conferences (World Congress of Cardiology, European Society of Radiology, etc.) easily meet these requirements because they draw attendees from around the world and are logically held in international venues. Smaller, less established conferences may face more scrutiny.

Cruise Ship Conferences

Conferences held on cruise ships have strict limitations:

• $2,000 annual deduction cap for all cruise ship conference expenses combined
• The ship must be a U.S.-flagged vessel that stops only at U.S. ports
• You must attach two statements to your return: (1) a signed statement from you showing days of the trip devoted to business and the hours of each day devoted to business, and (2) a signed statement from the conference sponsor showing the conference schedule and your attendance record

International Travel with Extended Personal Time

For international trips (outside North America), the allocation rules for mixed business/personal travel are stricter than for domestic travel. If the trip lasts more than one week and you spend more than 25% of the total days on personal activities, you must allocate transportation costs between business and personal use. For domestic travel, you generally deduct 100% of transportation if the primary purpose is business—but this more generous rule does not apply to international travel.

Proper documentation is the difference between a smooth audit and a devastating one. The IRS requires contemporaneous records for travel expenses—meaning records created at or near the time of the expense, not reconstructed months later at tax time.

The Four Elements of Every Travel Expense Record

For each travel expense, you need to document:

1. Amount — How much you spent (receipt or per diem rate)
2. Date — When you incurred the expense
3. Place — Where you traveled (city, state)
4. Business purpose — Why you traveled (specific assignment, conference name, meeting purpose)

Per Diem Documentation (Simplified)

One of the biggest advantages of the per diem method is simplified record-keeping. Instead of keeping every meal receipt, you only need:

• A log of travel dates and locations
• The business purpose of each trip
• The applicable per diem rate for each location (which you can look up on the GSA website)
• Records of any per diem reimbursements received from agencies or employers

How Long to Keep Records

• 3 years — Minimum retention period from the date you filed the return
• 6 years — If you underreported income by more than 25%
• 7 years — Recommended for physicians, especially those with complex multi-state filings
• Indefinitely — Keep records for any year where you didn't file a return or filed a fraudulent return
