Does mileage reimbursement cover gas for rental cars?
No. The standard mileage rate only applies to personal vehicles. For company or rental cars, the employer directly pays the rental fee and reimburses actual gas pump receipts.

Short answer
Yes, mileage reimbursement includes gas. The official standard mileage rate (such as the IRS rate of 72.5¢ Jan-Jun / 76¢ Jul-Dec 2026) is an all-inclusive figure designed to cover all variable vehicle operating costs (fuel, oil, maintenance, tires) and fixed ownership costs (insurance, registration, depreciation). Bridge tolls and parking fees are NOT included and must be reimbursed separately.
At a glance
- The standard mileage rate is an all-inclusive rate covering fuel, oil, repairs, tires, insurance, license fees, and depreciation.
- You cannot claim both the standard mileage rate AND separate gas receipts for the same trip (prohibited 'double dipping' under IRS rules).
- Bridge tolls, highway turnpike tolls, parking meters, and parking garage fees are separate incidental travel expenses reimbursed in addition to mileage.
- The IRS calculates standard mileage rates through an annual independent study of vehicle fixed and variable operating costs.
What Is Included vs. Excluded in Mileage Reimbursement
Understanding what costs the per-mile rate covers prevents duplicate reimbursement disputes and keeps expense claims compliant with tax standards:
| Expense Category | Covered in Per-Mile Rate? | How It Should Be Handled |
|---|---|---|
| Gasoline / Fuel / Electricity | Yes (Included) | Covered entirely by the per-mile rate; do not submit gas receipts. |
| Oil Changes, Fluids & Filters | Yes (Included) | Part of normal vehicle maintenance factored into the rate. |
| Tires, Brakes & Routine Repairs | Yes (Included) | Wear-and-tear allowance built directly into the federal cost study. |
| Vehicle Insurance & Registration | Yes (Included) | Fixed annual ownership costs amortized across business mileage. |
| Vehicle Depreciation / Lease Cost | Yes (Included) | Depreciation component included in the standard rate. |
| Highway & Bridge Tolls | No (Excluded) | Reimbursed separately at 100% actual cost with toll receipt / E-ZPass. |
| Parking Fees & Garage Charges | No (Excluded) | Reimbursed separately at 100% actual cost with parking receipt. |
| Traffic Fines & Speeding Tickets | No (Excluded) | Personal employee liability; never reimbursable under law. |

Can I Submit Gas Receipts AND Mileage Reimbursement?
No. Submitting a gas receipt while also receiving a per-mile mileage reimbursement for the same journey is considered 'double dipping'.
Under IRS Publication 463 and employer accountable plans, you must choose one method for each vehicle: either (1) standard mileage reimbursement (which already covers fuel), or (2) actual expense reimbursement (where actual gas, maintenance, and insurance receipts are tracked and apportioned by business-use percentage).
How the IRS Standard Mileage Rate Accounts for Fuel Prices
The IRS standard mileage rate is calculated through an annual nationwide economic study conducted by Runzheimer International. The study monitors retail fuel price movements across the United States alongside vehicle manufacturing and repair cost inflation.
When severe gas price spikes occur (such as in mid-2022 and mid-2026), the IRS issues mid-year rate adjustments to ensure the fuel component of the mileage rate accurately compensates drivers for surging pump prices.

Common questions
Why can't I submit gas receipts with standard mileage?
Because the standard per-mile rate already includes compensation for gasoline. Submitting a gas receipt on top of mileage reimbursement pays you twice for the same fuel, creating taxable excess reimbursement.
Are parking and tolls paid in addition to mileage?
Yes. Business-related parking fees and bridge/highway tolls are separate incidental travel expenses and should be claimed at 100% of actual cost with receipts.
