Deducting Medical Travel Expenses: Mileage, Airfare, and Lodging Rules for 2025

When you travel for medical treatment — to a specialist in another city, a major medical center, or a facility that offers specialized care — those travel costs are often deductible as part of your medical expense deduction. The IRS has specific rules about what transportation and lodging costs qualify. Here’s what you can deduct for medical travel in 2025.

What Medical Travel Costs Are Deductible?

The IRS allows a deduction for transportation costs primarily for and essential to medical care. This covers getting to and from medical appointments, treatments, or procedures — whether local or long-distance.

Driving to Medical Appointments: The Mileage Deduction

If you drive to medical appointments, you can deduct mileage at the IRS medical mileage rate — 21 cents per mile in 2025. This applies to driving yourself, a dependent, or a person you’re accompanying for medical care.

Alternatively, you can deduct actual out-of-pocket costs for gas and oil (but not depreciation, insurance, or general maintenance). The standard mileage rate is simpler for most people. In addition to mileage or gas, you can also deduct: parking fees at hospitals and medical offices, tolls paid during medical trips, and the cost of taxis, rideshares, buses, subways, or other transportation to medical appointments.

Long-Distance Travel for Medical Care

When you need to travel far from home for medical treatment — to a cancer center, specialized surgical facility, or medical center offering care unavailable locally — a broader range of travel expenses can be deducted:

Airfare — The cost of a plane ticket to travel to out-of-town medical treatment is deductible (lowest available fare for medical necessity)
Train and bus fares — For long-distance medical travel
Taxis and rideshares — At the destination, getting to and from the treatment facility
Car rental — If a rental car is necessary for medical travel at the destination

Lodging During Medical Travel

If you need to stay overnight while receiving medical treatment away from home, lodging costs can be partially deductible. The IRS rules for lodging deductibility:

The lodging must be primarily for medical care — not for personal reasons or tourism
The care must be provided by a physician in a hospital or similar institution
The lodging cannot be lavish or extravagant under the circumstances
Maximum deductible amount: $50 per night per person

The $50 per night limit applies to the patient. If a caregiver (spouse, parent, or other person accompanying the patient for essential medical support) also stays in the same or adjacent room, their lodging is also deductible at up to $50 per night — so a patient with a caregiver can potentially deduct up to $100 per night in lodging.

Important: Meals during medical travel are generally not deductible. The IRS specifically excludes meals from the medical travel deduction (unlike business travel, where 50% of meals may be deductible).

What Doesn’t Count as Deductible Medical Travel

The IRS is strict about the “primarily for medical care” requirement. The following are not deductible:

Vacation travel that includes medical appointments — If you go to a resort in Florida primarily for vacation but also have a checkup while there, the travel is not deductible. The primary purpose must be medical.
Travel to a climate for general health — Moving to or visiting a warmer climate for general health or recuperation (not specific medical treatment) is not deductible
Meals during medical travel — Explicitly excluded, as noted above
Luxury accommodations — Even if the lodging technically qualifies, you can only deduct the reasonable amount (subject to the $50/night cap for the allowed portion)

Practical Example: Medical Travel to a Cancer Center

Imagine you live in a rural area and travel to a major cancer center for chemotherapy. Over the course of a year, you make 12 trips. Each round-trip involves a 150-mile drive, one overnight stay, and a return drive.

Mileage deduction: 12 trips × 300 miles × $0.21 = $756
Lodging deduction: 12 nights × $50 = $600 (for patient)
If caregiver accompanies: additional $600 = $1,200 total lodging

Total medical travel deduction: up to $1,956 — added to your total qualifying medical expenses and subject to the 7.5% AGI floor.

Keeping Records for Medical Travel

Good recordkeeping is essential for medical travel deductions, especially since the IRS may scrutinize them. For each trip, record: date, destination and medical provider, medical purpose of the trip, miles driven (start and end odometer readings or map estimates), transportation receipts, and lodging receipts. A simple log or calendar notation for each medical visit, combined with receipts, provides solid documentation.

The 7.5% AGI Threshold

Medical travel costs, like all medical expenses, are combined with your other qualifying medical expenses and only the total exceeding 7.5% of your AGI is deductible. For people making frequent trips to medical providers — such as cancer patients, dialysis patients, or those undergoing ongoing treatment — the accumulated travel costs can be a meaningful part of the total deduction.

The Bottom Line

Transportation to medical appointments — by car, plane, bus, or rideshare — is deductible at established IRS rates and limits. Lodging for necessary overnight medical travel is deductible up to $50 per night per person. Meals are not deductible. The primary purpose of the travel must be medical care. Combined with other medical expenses, travel costs can meaningfully contribute to clearing the 7.5% AGI threshold and generating a real tax benefit.
