The Quick Answer by Deduction Method

The IRS gives self-employed people and business owners two ways to deduct vehicle costs. The one you use completely determines whether a car wash is deductible at all:

Standard Mileage Rate: Why Car Washes Are Already Included

The IRS standard mileage rate — 70 cents per mile in 2025 — is calculated each year based on the average costs of owning and operating a vehicle in the United States. That calculation includes:

• Gasoline and oil
• Tires and routine maintenance
• Car washes and detailing
• Insurance premiums
• Vehicle depreciation
• Repairs and parts

Because the rate already accounts for car wash costs on a per-mile basis, separately deducting car washes would mean claiming the same expense twice — which the IRS specifically prohibits.

What you can still deduct on top of the standard rate: parking fees and tolls you pay for business trips. That’s it. See our parking and tolls deduction guide for details.

Actual Expense Method: How to Deduct Car Washes

If you chose the actual expense method when you first started deducting vehicle costs, every legitimate vehicle operating cost — including car washes — is deductible based on your business-use percentage.

Step-by-step calculation

This $450 gets added to your other actual vehicle expenses (gas, insurance, repairs, depreciation) and reported on Schedule C, Part II, Line 9 as “Car and truck expenses.” You’ll also complete Form 4562 if claiming depreciation.

Can Rideshare Drivers Deduct Car Washes? (Uber, Lyft, DoorDash)

This is one of the most common questions — and the answer is the same as for any self-employed driver: it depends entirely on which vehicle deduction method you use.

Most rideshare and delivery drivers default to the standard mileage rate because it’s simpler and usually gives a larger deduction. Under that method, car washes cannot be deducted separately.

However, rideshare drivers who use their vehicle 90–100% for business and drive high-cost vehicles sometimes benefit more from the actual expense method — in which case car washes, interior cleaning supplies, and even professional detailing are all deductible at 90–100% of cost.

If you’re a rideshare driver, platforms like Uber and Lyft report your earnings on a 1099-K or 1099-NEC. You report this income on Schedule C and deduct vehicle expenses on the same form. Use our mileage calculator to see which method is worth more for your situation.

What About Car Detailing?

Detailing — interior cleaning, exterior polishing, engine bay cleaning — is treated identically to a standard car wash by the IRS. It’s a vehicle cleaning/maintenance cost under Publication 463.

• Standard mileage rate: Detailing is included in the rate. Not separately deductible.
• Actual expense method: The business-use percentage of detailing costs is fully deductible.

If you get your vehicle detailed specifically for a documented business purpose — photographing a client’s property, transporting an important client, preparing a fleet vehicle for service — make note of that business reason in your records. It can strengthen the deduction and shows intent if questioned.

Are Car Washes Deductible for Self-Employed People?

Yes, under the actual expense method. Self-employed individuals — freelancers, independent contractors, small business owners — use Schedule C to report business income and expenses. Vehicle costs including car washes are deductible under the actual expense method as long as you can document the business-use percentage.

The same rule applies whether you’re a sole proprietor, single-member LLC, or partnership. S-corp and C-corp owners whose vehicles are owned by the business can deduct 100% of car wash costs (since the business owns the vehicle and all use is business use by definition).

Can I Deduct Car Washes as a Business Vehicle Expense?

If the vehicle is owned by your business (not personally), and the vehicle is used exclusively for business, then yes — 100% of car wash and cleaning costs are a legitimate business expense. This is most common for LLCs, S-corps, or C-corps with company vehicles.

If you’re a sole proprietor with a personal vehicle used partly for business, you’re back to the actual vs. standard mileage choice — and only the business-use percentage is deductible under the actual method.

Is an Automatic Car Wash Membership Deductible?

Monthly car wash memberships (like the unlimited plans many gas stations and dedicated car washes now offer) follow the same rules:

• Standard mileage rate: Not separately deductible — it’s included in the rate.
• Actual expense method: The business-use percentage of the monthly membership fee is deductible. If you pay $30/month ($360/year) and use the car 70% for business, $252 is deductible.

A membership is treated the same as individual wash visits — it’s still a vehicle cleaning cost under Pub 463.

Which Method Is Right for You?

If deducting car washes specifically matters to you, run both calculations to see which method gives you a larger total deduction. The standard mileage rate is simpler and wins for most drivers, but the actual expense method can pull ahead if you have a high-cost vehicle or high actual expenses.

Use our mileage calculator to estimate your standard rate deduction, then compare it to your actual expenses for the year. If actual expenses are higher, switch to that method — you’ll capture car washes, detailing, and all other vehicle costs.
