Driver Mileage Reimbursement and IRS Rules for Restaurants

The most common way restaurants reimburse delivery drivers is also the most litigated. Here is the math behind a defensible number, and the paperwork that keeps it out of your payroll taxes.

A driver runs 62 deliveries in a two-week pay period. You pay $1.25 per run, which comes to $77.50, and it has never been a line anyone questioned. Then a former driver's attorney pulls the delivery records, multiplies 62 runs by an average round trip of 5.8 miles, and lands on 360 miles. Divide the $77.50 by 360 and the reimbursement rate is 21.5 cents per mile. That is the number that ends up in a complaint.

The problem is not that flat fees are forbidden. They are not. The problem is that most flat fees were set years ago, never recalculated, and cannot survive division. Meanwhile the driver's real costs — gas, insurance, tires, brakes, and the depreciation of using a personal car for commercial mileage — kept climbing. Every quarter the gap widens quietly, and nothing in your P&L flags it, because the reimbursement line looks small and stable. That is precisely why it looks fine right up until it does not.

Agitating this further: under federal wage law, an unreimbursed expense that primarily benefits the employer is treated as if you had deducted it from the paycheck. For a tipped driver paid a reduced cash wage, there is very little cushion between the cash wage and the federal floor, so a shortfall of even 30 cents a mile can push effective pay under the minimum. Multiply by a few drivers and a few years and the exposure stops being theoretical.

The good news is that this is a solvable arithmetic problem with a well-marked path. Get the reimbursement method right, document it under an accountable plan, and you convert a lingering liability into a clean, deductible expense that your drivers actually appreciate.

The Two Legal Frames You Are Operating In

Driver reimbursement sits at the intersection of two different rulebooks, and operators get in trouble by satisfying one and ignoring the other.

Frame One: The IRS and Whether It Is Taxable

The IRS cares about whether the money you hand a driver is a reimbursement or wages. Under an accountable plan, described in the regulations under Section 62, the payment is not wages at all: it is not reported on the W-2, and neither you nor the driver pays payroll tax on it. Three tests must all be met:

• Business connection. The expense was incurred doing your work, in the course of employment.
• Substantiation. The driver documents the date, purpose, and mileage within a reasonable period, generally within 60 days of the expense.
• Return of excess. Any advance beyond the substantiated amount is returned, generally within 120 days.

Fail any one of the three and the entire payment becomes a non-accountable plan payment: taxable wages, subject to income tax withholding, Social Security, Medicare, and unemployment tax. That is roughly 7.65% of employer payroll tax on money you were already spending, plus the same hit to the driver's take-home.

Frame Two: Wage Law and Whether It Is Enough

The Department of Labor's position is that vehicle expenses incurred primarily for the employer's benefit cannot reduce a worker's pay below the minimum wage. Two reimbursement approaches are generally recognized as adequate: paying at the IRS business standard mileage rate, or paying a reasonable approximation of actual expenses that you can document.

That phrase — reasonable approximation — is where the litigation lives. A flat fee is a reasonable approximation only if someone actually did the approximating, with real vehicle-cost data and real trip distances, and revisits it as costs change. A number inherited from the previous owner does not qualify.

Comparing the Three Reimbursement Methods

Three approaches cover nearly every restaurant delivery operation. They differ sharply in administrative burden and in how well they hold up under challenge.

The standard mileage rate has run in the high-60s to low-70s cents per business mile in recent years, most recently 70 cents for 2025, and the IRS publishes a fresh figure each December. Whatever the current rate is, using it is the cleanest option available, because it doubles as both an IRS-blessed reimbursement amount and a wage-law safe harbor.

Now run the comparison on real volume. Take a driver logging 360 miles over 62 deliveries in a pay period:

The spread between the top and bottom row is about $175 per driver per pay period, or roughly $4,500 a year for one full-time driver. That is the number to weigh against the cost of a wage claim, which in practice includes back pay, liquidated damages, and the other side's attorney fees.

What "Actual Cost" Really Includes

Operators who choose the approximation route usually underbuild it, counting gas and stopping. A credible per-mile figure has five components, and four of them are invisible at the pump:

• Fuel. Local price divided by the vehicle's real-world mpg, which for stop-and-go delivery driving is well below the sticker number.
• Maintenance and tires. Oil changes, brakes, and tires wear on a mileage clock, not a calendar one. Delivery duty accelerates all three.
• Depreciation. Usually the largest single line and the one nobody feels. Commercial mileage on a personal car is real value transferred from the driver to your P&L.
• Insurance. Personal auto policies commonly exclude delivery use, so a driver doing this properly carries a business-use endorsement that costs more. This interacts directly with your own coverage decisions, which is why delivery insurance planning and reimbursement policy should be designed together.
• Registration and fees. Small, but part of the honest total.

Build the figure once with your CPA, write down the sources and the date, and revisit it annually. The written study is the artifact that makes the number a "reasonable approximation" instead of an assertion.

The Recordkeeping That Makes It Work

Substantiation is where good intentions collapse, because most restaurants ask drivers to write miles on a sheet at the end of a shift. Reconstructed numbers are exactly what auditors and plaintiffs' attorneys look for. Here is the standard to hold:

1. Per-trip records, captured contemporaneously. Date, business purpose, and distance for every reimbursed trip. Route data from your dispatch system satisfies this and removes the honor system entirely, which is one of the practical arguments for GPS tracking on delivery drivers.
2. A per-pay-period reconciliation. Total substantiated miles times the rate, matched to the amount actually paid. Any difference should be explainable in one sentence.
3. A written policy the driver signs at hire. Rate, method, submission deadline, and the requirement to return unsubstantiated advances. Fold it into your driver onboarding checklist so it is never an afterthought.
4. Separation on the pay stub. Reimbursement shown as a distinct non-taxable line, not blended into wages or tips. Blending is how an accountable plan quietly stops being one.
5. Retention for at least four years. Employment tax records generally must be kept four years; wage claims often reach back two to three.

How This Changes Your Delivery Economics

Reimbursing correctly raises the variable cost of every mile, and that is not a bad thing — it makes the true cost of distance visible. Once mileage is priced honestly, several decisions get easier:

Long-haul orders stop looking free. A 9-mile round trip at 50 cents costs $4.50 in reimbursement alone before wages, which is a direct input into revenue-per-mile analysis and often the argument for trimming the far edge of a zone or charging a distance-based fee. Batching gains real value, since two orders on one run halve the per-order mileage cost. And the whole compensation structure deserves a second look, because the balance of hourly wage, tips, and reimbursement is what drivers actually compare when they choose between you and the gig apps — the tradeoffs are laid out in the common driver compensation models.

On the tax side, reimbursements paid under an accountable plan are an ordinary and necessary business expense and are deductible in full, alongside the other write-offs covered in this restaurant tax deductions guide. Handled as wages instead, you are paying employer payroll tax for the privilege of the same expense. Fitting reimbursement into the broader delivery driver management program — scheduling, coaching, retention — is what turns a compliance chore into a hiring advantage.

Five Mistakes That Create Exposure

• Setting a flat fee and never dividing it by miles. Do the division every year. If the result is under 40 cents, you have work to do.
• Blending reimbursement into wages on the stub. It defeats the tax treatment and makes the payment look like compensation in a wage dispute.
• Accepting end-of-week estimated mileage. Contemporaneous means per trip. Systems that capture it automatically remove the problem.
• Assuming a 1099 fixes it. Misclassifying drivers who are directed, scheduled, and supervised like employees converts one exposure into a larger one.
• Ignoring state law. Several states require reimbursement of necessary business expenses regardless of the federal minimum wage math, with their own penalties.
