You can write off an RV as a business expense, but only to the extent the vehicle actually earns its keep in your business, and only if you can prove it with the kind of records the IRS demands for assets that double as personal toys. Every deduction on an RV traces back to three things: a real business purpose, a contemporaneous mileage log, and the specific depreciation rules Congress wrote for vehicles like this one.
Your Business Has to Actually Need the RV
Under Internal Revenue Code Section 162, a deductible expense must be ordinary and necessary for your trade or business. Ordinary means common and accepted in your line of work. Necessary means helpful and appropriate, not that you couldn’t function without it.
For an RV, the practical question is whether your business genuinely calls for one. A mobile veterinarian driving a converted RV between rural clinics has a much easier case than a consultant who flies to meetings and takes the RV on the occasional road trip. The tighter the link between the vehicle and how you earn income, the fewer problems you’ll have if the return is examined.
The business itself also has to look like a business. Under IRC Section 183, an activity is presumed to be for profit if it produces a net profit in at least three of five consecutive tax years. Fall short and the IRS can reclassify the venture as a hobby, which caps deductions at the income the activity produces. An RV write-off resting on top of a business that never turns a profit is a write-off the IRS will eventually take apart.
The Mileage Log Is Not Optional
RVs are “listed property” under IRC Section 280F because they’re the kind of asset people routinely use for personal reasons. The label triggers documentation rules that go beyond normal business record-keeping.
You need a contemporaneous log for every trip: date, destination, business purpose, and mileage. A log reconstructed weeks or months later won’t pass. IRS Publication 946 is blunt on the consequence: without adequate records, you cannot take any depreciation or Section 179 deduction on listed property.
Your business-use percentage is business miles divided by total miles for the year. Drive 15,000 miles and log 10,000 for business, and you’re at 66.7%. That percentage becomes the ceiling on every RV-related deduction you claim, from fuel to depreciation. Keep receipts for both capital and operating costs, and note the business purpose on each.
One myth to bury before it costs you: wrapping the RV in company advertising does not turn personal miles into business miles. Publication 463 says so directly. A logo on the side doesn’t change the character of a trip to the grocery store.
Operating and Travel Costs You Can Deduct
Day-to-day costs of running the RV are deductible at your business-use percentage. Fuel, oil, repairs, maintenance, insurance, and registration all follow that allocation. A $2,000 insurance premium at 65% business use produces a $1,300 deduction. Costs tied to personal trips are never deductible.
Campground and parking fees paid while you’re away from your tax home on business are deductible travel expenses. Your tax home is the city or general area where your main place of business sits, not necessarily where your family lives. Parking at your home base, or during personal downtime, is a personal expense. Propane, electrical hookups, and other utilities at a job site follow the same allocation as other operating costs.
No Standard Mileage Rate for RVs
The 2026 IRS standard mileage rate of 72.5 cents per mile is available only for cars, vans, pickups, and panel trucks. An RV doesn’t qualify. You have to track and deduct actual expenses, which is why the log and receipts matter so much.
Meals on the Road
When you’re away from your tax home overnight for business, meals are deductible. Rather than saving every receipt, you can use the IRS standard meal allowance, a fixed daily rate drawn from federal per diem tables. There’s no equivalent flat rate for lodging; document actual costs. If you sleep in the RV, your campground fee is your lodging cost.
Writing Off the Purchase Price
The purchase price is a capital cost, recovered over time through depreciation under the Modified Accelerated Cost Recovery System (MACRS). A self-propelled motorhome generally falls into the five-year MACRS class as a motor vehicle used for transportation. Your depreciable basis is the purchase price multiplied by your business-use percentage, and salvage value is ignored.
On a $120,000 motorhome used 65% for business, the depreciable basis is $78,000. Without any acceleration, that $78,000 spreads across five years under the declining-balance method MACRS prescribes.
Section 179 Expensing
Section 179 lets you deduct the full cost of qualifying business property in the year you place it in service. For 2026, the maximum Section 179 deduction is $2,560,000. Two constraints matter more than the ceiling for most RV buyers.
First, the deduction can’t exceed your net taxable income from all active trades or businesses. If the business earns $50,000 and the RV’s depreciable basis is $78,000, you can only expense $50,000 under Section 179 this year. The rest carries forward.
Second, gross vehicle weight matters. RVs with a GVWR between 6,000 and 14,000 pounds are subject to a lower Section 179 cap of roughly $32,000. Heavier RVs, including many Class A motorhomes above 14,000 pounds GVWR, are not subject to that SUV-style limit and can potentially expense the full depreciable basis under the general Section 179 ceiling.
100% Bonus Depreciation
The One, Big, Beautiful Bill enacted a permanent 100% bonus depreciation deduction for eligible property acquired after January 19, 2025. For an RV placed in service in 2026, that means you can deduct the entire depreciable basis in year one, on top of any Section 179 deduction, provided business use exceeds 50%. Bonus depreciation is applied after Section 179 and before regular MACRS on whatever basis remains.
Between Section 179 and 100% bonus depreciation, many owners can write off the entire business portion of the RV’s cost in the year of purchase. Depreciation is reported on Form 4562.
The 50% Business-Use Trap
Both Section 179 and bonus depreciation require more than 50% business use in the year the RV is placed in service. At or below 50%, you’re stuck with slower straight-line depreciation over the MACRS recovery period.
The risk continues after year one. If you claim accelerated depreciation and then business use drops to 50% or less in any later year during the recovery period, you trigger depreciation recapture. The IRS calculates the difference between what you actually deducted and what straight-line would have allowed, and that excess is added back to ordinary income in the year of the drop. On a six-figure RV, the recapture bill can be brutal. Keep the mileage log every year, not just the first.
RV Loan Interest
Financing splits the interest deduction two ways. The business-use portion of loan interest is deductible as a business expense on Schedule C. A 65% business-use RV with $4,000 in annual interest produces a $2,600 business interest deduction.
The personal-use portion may still be deductible under a different rule. The IRS treats an RV as a “qualified home” for mortgage interest purposes if it has sleeping, cooking, and toilet facilities. If it does, interest on the personal share of the loan can be deducted as home mortgage interest on Schedule A, subject to the $750,000 debt limit for loans taken out after December 15, 2017. This works whether the RV is your main home or a second home. You can also elect to treat the debt as not secured by your home if the business interest deduction gives a better result.
Home Office Inside an RV
If you live and work in the RV, a portion of its expenses may qualify for the home office deduction. The IRS defines “home” broadly enough to include mobile homes, boats, and similar property with basic living accommodations, so an RV qualifies.
The requirements are strict. You need a separately identifiable space used exclusively and regularly for business. A dinette that’s your workspace by day and your dining table at night fails the exclusive-use test. The space must also be your principal place of business or a location where you regularly meet clients. Full-time RV business owners often meet the principal-place standard because that’s where the administrative and management work happens.
Under the regular method, you calculate the percentage of the RV’s floor area dedicated exclusively to the office and deduct that percentage of eligible expenses: depreciation, insurance, utilities, maintenance. A 30-square-foot workspace in a 300-square-foot RV is 10%. Report the deduction on Form 8829, flowing to Schedule C.
The simplified method gives you $5 per square foot of dedicated office space, capped at 300 square feet, for a maximum of $1,500 a year. No Form 8829. For a small workspace, the simplified method usually produces a smaller deduction than the regular method, but it eliminates the tracking. Either way, the exclusive-use and regular-use tests still apply.
What Happens When You Sell
Selling a business-use RV can produce a tax bill that catches owners off guard. Every dollar of depreciation you claimed, or were allowed to claim even if you didn’t, reduces the RV’s adjusted basis.
When you sell for more than the reduced basis, gain up to the total depreciation you claimed is taxed as ordinary income under Section 1245 depreciation recapture. Any gain beyond that amount is treated as a Section 1231 gain, which gets the more favorable capital gains treatment. Sell for less than the adjusted basis and the loss is generally deductible as an ordinary business loss. Report the sale on Form 4797.
Employees Are in a Different Position
Everything above assumes you’re self-employed or own a business. Sole proprietors and single-member LLC owners claim RV expenses on Schedule C. Partners and S-corporation shareholders can claim the deductions through their entities, with different mechanics.
W-2 employees face a different situation. The Tax Cuts and Jobs Act suspended the deduction for unreimbursed employee business expenses starting in 2018. Whether that suspension continues into 2026 depends on later legislation, and the rules have moved. If you’re an employee thinking about an RV as a work vehicle, confirm eligibility with a tax professional before buying. Reimbursement from an employer under an accountable plan is typically the safer route.
