Can I Deduct Mileage to Buy Supplies for My Airbnb?

Yes — every trip you make to buy supplies for your short-term rental is deductible business mileage under IRC §162(a). The IRS treats these runs to Costco, Target, Home Depot, or anywhere else you buy STR supplies the same as any other business trip: ordinary, necessary, and fully deductible at the standard rate. You just need a log that records what you bought and why.

Why Supply Run Mileage Is Deductible

IRC §162(a) allows a deduction for ordinary and necessary business expenses. Buying supplies to stock your STR — toilet paper, cleaning products, coffee, soap, light bulbs, towels — is clearly ordinary and necessary. The transportation cost to acquire those supplies is part of the business expense.

The same standard that makes the supplies themselves deductible on Schedule C Line 22 makes the mileage to acquire them deductible on Line 9 (or however you record car/truck expenses). You get both deductions: the supply cost and the miles driven to buy them.

Real Dollar Impact

An active STR host who makes two supply runs per month (24 trips/year) at an average of 15 miles round-trip deducts 360 miles × $0.725 = $261 from supply runs alone. Add property visits, contractor meetings, and other trips and total mileage deductions easily reach $800–$2,000+ per year for a single property. See the full picture in our complete mileage deduction guide.

Which Supply Runs Qualify

The test is whether the primary purpose of the trip is to purchase items for your STR business. If you're heading out specifically to buy something your rental needs, those miles count. Here's a breakdown:

Clearly Deductible Supply Trips

Mixed Trips: Personal + Business

If you stop at the grocery store to buy personal food and pick up coffee for your STR, the trip is mixed-use. The IRS rule: if the primary purpose of the trip is business, you can deduct the mileage for the trip. You cannot deduct incremental miles for purely personal detours. The safest approach is to keep supply runs separate from personal errands when possible.

Watch Out

Don't try to deduct your regular grocery run as an STR supply trip just because you bought coffee or cleaning spray while there. The IRS looks at the primary purpose of the trip. If you're doing your weekly grocery shopping and happen to grab some paper towels for the rental, that's a personal trip with an incidental business purchase — not a deductible business drive.

What You Need to Record for Each Trip

Under IRC §274(d), mileage deductions require strict substantiation. You must have a contemporaneous record — recorded at or near the time of travel — with these five elements:

A note like "4/6/26 — Home to Target, 8.4 miles RT, bought cleaning supplies and guest toiletries for STR" is exactly the kind of documentation that survives IRS scrutiny. Vague entries like "store run" will not. For a complete breakdown of log requirements, see our mileage log requirements guide.

Standard Mileage Rate vs. Actual Costs

For most STR hosts, the standard mileage rate is the simpler and often more valuable option. The 2026 rate is $0.725 per mile. You multiply your total business miles by that rate — no need to track gas, maintenance, insurance, or depreciation separately.

Annual Supply Run Miles Deduction at $0.725/mi
100 miles$72.50
250 miles$181.25
500 miles$362.50
1,000 miles$725.00

Pro Tip

Save the receipt from every supply run and attach it to your mileage log entry for that trip. Receipts don't prove mileage, but they corroborate the business purpose — which is exactly what an IRS auditor wants to see. If your log says "bought cleaning supplies" and you have a Home Depot receipt for the same day, that's a solid record.

Tracking Your Supply Run Mileage All Year

The biggest mistake STR hosts make with supply run mileage is failing to track it in real time. These trips are small, frequent, and easy to forget. By December, you genuinely cannot remember how many times you drove to pick up paper towels.

The solution is a system that captures trips automatically. Options include:

Whatever system you use, it must be contemporaneous. Year-end reconstruction of supply run mileage is risky and often disallowed under §274(d). See our complete Airbnb tax deductions guide for how supply mileage fits into your overall deduction strategy.
