A car allowance is a fixed, taxable payment for vehicle costs (like insurance, maintenance, fuel), while mileage reimbursement pays a non-taxable cents-per-mile rate for actual business driving, requiring expense reports. The allowance offers predictable income but can overpay or underpay depending on actual use, whereas mileage directly rewards distance but can be unfair to low-mileage drivers; a dual approach (allowance plus mileage) can cover both fixed and variable costs but is costlier for employers.
Reimbursing employees for miles traveled is much more accurate than simply issuing a flat-rate car allowance. By reimbursing for only what they've traveled, employers are neither wasting money by overpaying nor shirking responsibility to their employees by giving too little an allowance.
Disadvantages of Car Allowances
Car allowances do not ensure coverage of all vehicle-related expenses. Employees bear responsibility for insurance, maintenance, depreciation, and other costs. Because the IRS treats most car allowances as taxable income, the take-home amount may fall short of actual expenses.
That means you can't deduct mileage if you receive a car allowance – and you shouldn't expect your employees to.
However, most sources land in the same range: the average car allowance was between $575 to $600 per month in 2024. In 2025, the average car allowance rose to just over $700 per month (Source: Internal Cardata aggregated data 2025).
A car allowance is often not required and is frequently negotiated as part of an employment contract. A car allowance for employees is also typically granted as a predetermined monthly sum rather than being linked to the employee's actual costs.
use your car allowance to cover the running costs of your current car. this option means you don't change much. you keep the car that you own and you put your car allowance towards the running costs of your car. because your car allowance is itemised on your salary slip, you will get the tax benefits.
With a car allowance you can decide on how the funds are spent but the most common uses are:
How should a car allowance be taxed? Because a standard car allowance is a non-accountable plan, it should be taxed as W-2 income. The employer should withhold federal income taxes, FICA/Medicare, and state income taxes on the full allowance amount. The car allowance should be taxed at the employee's income bracket.
Typically, a fair charge is between 45p and 50p per mile based on HMRC's recommended rates. This recommended rate covers the costs of fuel, vehicle wear and tear and other running costs. In areas where fuel and other costs are higher, tradespeople may charge up to 60p per mile.
There's no single answer to whether the standard mileage rate method or the actual expenses method is better. Each has its pros and cons, and the best choice depends on your business's driving habits, vehicle costs, and how much time you're willing to spend on recordkeeping.
The IRS recognizes another non-taxable approach to vehicle reimbursement called FAVR reimbursement, or a fixed and variable rate allowance. This program holds several key advantages over a car allowance or mileage rate, making it the most desirable alternative to a company car.
The IRS generally treats a vehicle allowance as taxable income. This is due to the fact that a car allowance is not attributable to mileage. Because of this, a vehicle allowance is considered compensation and, therefore, is taxed.
While it's a good idea to consider the age of a vehicle and the number on its odometer, it's much more crucial to look at how well the owner maintained the car. A decade-old car with 100,000 miles may have received more TLC than a 5-year-old model with 50,000 miles.
If you exceed the agreed mileage you decrease the value of the vehicle and, if you return it, you will incur excess mileage charges plus VAT. Please click here and view Page 1 to see examples of how excess mileage charges are calculated.
You can claim mileage on taxes based on the IRS standard rates, which for 2025 are 70 cents per mile for business, 21 cents for medical/military moving, and 14 cents for charitable work, with even newer 2026 rates set at 72.5 cents for business, allowing you to deduct a fixed amount per qualified mile driven for work, charity, or medical reasons, or use the more complex actual expenses method for larger deductions if your vehicle costs are high.
The car allowance can be taxable as income to the employee. Reimbursement is typically a low mileage solution and can be cost-effective if your employees travel less than 10,000 miles a year. But for businesses that require employees to travel more frequently, a company vehicle makes more sense economically.
Many drivers may be overpaid, while others will receive an amount too small to make up for their driving expenses. Since car allowances are taxed, it's even less likely to cover a mobile worker's needs. And, with the passage of the TCJA, they can no longer deduct unreimbursed business mileage from their taxes.
A car allowance negotiation is a collaborative process, not a confrontational one. You want to build rapport and trust with the employer, not antagonize or offend them. You want to present your request as a win-win proposition, not a demand or an ultimatum.
Anything below the standard mileage rate is non-taxable
One way to ensure you provide a non-taxable car allowance is to verify your employees' mileage for a certain period of time and then reimburse them. This allowance will remain tax-free as long as it's not above the IRS standard mileage rate for business travel.
A car allowance is a periodic stipend paid to an employee for using a vehicle. It is usually taxable. A mileage reimbursement is a cents-per-mile rate multiplied by the employee's monthly mileage amount. If it is equal to or less than the IRS standard rate, it is non-taxable.
And, believe it or not, the average car allowance in 2020, 2021, 2022 and 2023 was also $575. This amount hasn't changed much over the past few years because car allowances aren't as concerned with accuracy as other programs that take mileage and car maintenance into consideration.
Company Car or Car Allowance, Which is Better? Ultimately, it's a question of finance. Weighing up the benefits, if you're financially able to insure, service and maintain a car, an allowance is a good way to go. It offers you the freedom of choice and gives you a cash sum, which offers flexibility.
The 20/3/8 rule is a car-buying guideline suggesting you put 20% down, finance for 3 years or less, and keep your total monthly car expenses to 8% or less of your gross income, helping to ensure you buy reliable transportation without overspending and can still invest in other goals like retirement. It's a tool to avoid being "underwater" on your loan (owing more than the car's worth) and to prioritize financial health over luxury vehicles.
