Standard Mileage Rate vs Actual Expenses for STR Hosts
No credit card required
For most STR hosts, the standard mileage rate is simpler to use and often produces a larger deduction than tracking actual vehicle expenses. The 2026 rate is $0.725 per mile under Rev Proc 2024-58, governed by IRC §274(d). But if you drive an expensive vehicle primarily for your rental business, actual expenses can win — here's exactly how to decide.
The Two Methods: A Side-by-Side Overview
The IRS gives you two ways to deduct vehicle costs for your STR business. You choose one per vehicle per year (with some switching restrictions):
| Factor | Standard Mileage | Actual Expenses |
|---|---|---|
| Calculation | Miles × $0.725 | Business % × total costs |
| Records needed | Mileage log only | All receipts + mileage log |
| Depreciation | Built into rate | Separate (MACRS or Sec. 179) |
| Complexity | Low | High |
| Best for | Most hosts | High-cost, high-business-use vehicles |
Under IRC §274(d), both methods require a mileage log. Even with actual expenses, you must track business vs. personal miles to calculate your business-use percentage. There is no vehicle deduction without a log.
How the Standard Mileage Rate Works
The standard mileage rate (set annually by the IRS via Rev Proc) bundles gas, oil, tires, maintenance, insurance, registration, and depreciation into one per-mile rate. For 2026, that rate is $0.725 per mile.
Your deduction is simple: Total business miles × $0.725. If you drove 2,000 business miles for your STR in 2026, your vehicle deduction is $1,450. No receipts for gas or oil changes needed — just the mileage log.
You can still deduct parking fees and tolls on top of the standard mileage rate. Loan interest on the vehicle is also separately deductible at the business-use percentage.
STR host with one property 15 miles away. Makes 80 trips per year (property visits, supply runs, contractor meetings). That's approximately 2,400 miles × $0.725 = $1,740 deduction. No gas receipts required.
How the Actual Expense Method Works
With actual expenses, you add up every vehicle cost for the year — gas, insurance, maintenance, repairs, registration, and depreciation — then multiply by the business-use percentage (business miles ÷ total miles driven).
For example: $8,000 total vehicle costs × 30% business use = $2,400 deduction. The benefit over standard mileage is real only if your actual per-mile costs exceed $0.725, which typically requires either a high-cost vehicle or significant maintenance expenses.
What Counts as Actual Expenses
- Gasoline and oil
- Insurance premiums (business-use percentage)
- Repairs and maintenance
- Tires
- Vehicle registration and license fees
- Depreciation (MACRS or Section 179)
- Lease payments (if leasing)

Which Method Wins for STR Hosts?
Run both calculations for your situation. Here are the general rules:
Standard Mileage Usually Wins When...
- You drive a fuel-efficient or average-cost vehicle
- Your STR is a side business and you use the car mostly for personal driving
- You don't want to save every gas receipt and maintenance record
- You're in the first year and want to preserve flexibility to switch methods later
Actual Expenses May Win When...
- You drive a new, high-value truck or SUV primarily for your STR business
- You use the vehicle 70%+ for business and have high actual operating costs
- You had a major repair or maintenance expense in the current year
- You want to layer in Section 179 or bonus depreciation for a large first-year write-off
If you use actual expenses and claim accelerated depreciation (Section 179 or bonus) in year one, you cannot switch to standard mileage in future years for that vehicle. Starting with standard mileage preserves the option to switch to actual expenses later. Choose carefully — this is a decision to review with your CPA.
The Record-Keeping Reality
Both methods require a contemporaneous mileage log per IRC §274(d). The actual expense method additionally requires you to save every gas receipt, insurance bill, maintenance invoice, and registration notice for the year.
For most STR hosts, the administrative burden of actual expense tracking isn't worth the marginal difference in deduction — especially when the standard rate already bakes in all those costs.
