Can I Deduct Car Accessories from Amazon for My Business?

If you're self-employed and use your vehicle for business, car accessories from Amazon may be tax deductible—but the answer depends on whether the accessory serves a business purpose, which deduction method you're using, and how well you document the expense. The IRS allows vehicle-related deductions through two methods: standard mileage or actual expenses. Car accessories typically only matter if you use the actual expense method.

For example, if a freelance contractor uses their pickup truck primarily for business and purchases a toolbox from Amazon to transport equipment to job sites, that accessory may be deductible as a car and truck expense on Schedule C. However, if someone buys a decorative air freshener or steering wheel cover for personal comfort, that would not qualify as a business expense.

The key distinction is business necessity versus personal preference. Accessories that enable or improve business use of the vehicle—like cargo organizers for delivery drivers or dash cams for ride-share operators—have a stronger case for deductibility than items used for comfort or aesthetics.

Why This Is Confusing for Self-Employed Business Owners

Most self-employed individuals buy car accessories on Amazon without thinking about tax implications at purchase time. Months later, during tax season, they wonder: "Can I deduct that phone mount? What about the dash cam? The floor mats?"

The confusion stems from several factors:

Two deduction methods. The IRS allows you to deduct vehicle expenses using either the standard mileage rate (70 cents per mile for 2025) or the actual expense method. Many business owners don't realize that car accessories generally only matter under the actual expense method—the standard mileage rate already bundles most vehicle costs into the per-mile calculation.

Business use vs. personal use. If you use your vehicle for both business and personal purposes, only the business portion of expenses is deductible. A dash cam installed in a vehicle used 60% for business would be 60% deductible under actual expenses.

Ordinary and necessary test. Not all car accessories pass the IRS test. A toolbox for a contractor transporting equipment is ordinary and necessary. A luxury seat cover for personal comfort is not.

Documentation requirements. Without documentation showing business purpose and usage, claiming car accessory deductions becomes risky during an audit.

When Car Accessories Could Be Deductible

Car accessories from Amazon may be tax deductible if ALL of the following conditions are met:

1. You're Self-Employed and File Schedule C

If you're a 1099 contractor, freelancer, sole proprietor, or single-member LLC owner filing Schedule C, you may deduct car and truck expenses. W-2 employees cannot deduct unreimbursed vehicle expenses on their federal return (this rule has been in place since 2018).

2. You Use the Actual Expense Method

The IRS offers two ways to deduct vehicle costs:

Standard mileage rate: For 2025, you deduct 70 cents per mile for business driving. This rate already includes gas, maintenance, insurance, depreciation, and wear-and-tear. Under this method, you generally cannot separately deduct individual car accessories—they're already factored into the rate.

Actual expense method: You deduct the actual costs of operating your vehicle: gas, repairs, insurance, registration, lease payments, and yes—car accessories that serve a business purpose. This is the method where accessory deductions matter.

Important: If you choose the actual expense method the first year you start using your car for business, you're locked into that method for the life of the vehicle. If you choose standard mileage the first year, you can switch between methods in future years.

3. The Accessory Serves a Business Purpose

The IRS requires expenses to be "ordinary and necessary" for your business. An ordinary expense is one that is common and accepted in your trade or business. A necessary expense is one that is helpful and appropriate for your business.

Examples of potentially deductible car accessories:

• Dash cams - For ride-share drivers (Uber, Lyft), delivery drivers, or business owners who need documentation for insurance or liability purposes
• Phone mounts - For drivers who use GPS navigation for client visits, deliveries, or service calls
• Cargo organizers, toolboxes, storage systems - For contractors, electricians, plumbers, or mobile service providers who transport equipment
• Heavy-duty floor mats or cargo liners - For vehicles used to transport materials that cause wear and tear
• Roof racks or cargo carriers - For businesses that regularly transport equipment or inventory
• Winches or towing equipment - If used specifically for business operations (e.g., landscaping business moving equipment)
• Vehicle tracking devices - For fleet management or mileage documentation
• First aid kits or safety equipment - If required for your type of business

Examples of generally NOT deductible accessories:

• Decorative items (air fresheners, seat covers, steering wheel covers) unless they serve a business purpose
• High-end stereo systems or entertainment upgrades
• Tinted windows (unless required for business security)
• Vanity license plates
• Personal comfort items (heated seats, massage cushions)

4. You Allocate Based on Business Use Percentage

If you use your vehicle for both business and personal purposes, you must calculate the business use percentage and only deduct that portion of the accessory cost.

Example calculation:

Let's say a freelance photographer uses their SUV for business shoots and personal errands. Their annual mileage:

• Total miles driven: 15,000
• Business miles: 9,000
• Personal miles: 6,000
• Business use percentage: 9,000 ÷ 15,000 = 60%

If they purchase a $200 cargo organizer from Amazon to transport camera equipment:

• Full cost: $200
• Business portion: $200 × 60% = $120 deductible

The entire $200 goes into your vehicle expense tracking, but only 60% ($120) is deductible on Schedule C.

5. You Keep Documentation

To support a deduction, you need:

Purchase documentation:

• Amazon order confirmation email
• Receipt showing item description, price, date
• Credit card or bank statement

Business purpose documentation:

• Written explanation of how the accessory supports your business
• For mixed-use vehicles: mileage log showing business vs. personal use percentage
• For expensive items: Photos or installation records

Tools like Purchase Deductions can help by automatically generating business purpose documentation when you forward Amazon order emails, categorizing purchases using IRS Schedule C categories, and calculating deductible amounts based on your business use percentage.

When Car Accessories Are NOT Deductible

Car accessories from Amazon are generally NOT deductible in these situations:

You're a W-2 Employee

Employees who use their personal vehicle for work cannot deduct unreimbursed vehicle expenses on their federal return. This has been the rule since 2018 tax law changes.

Exception: If your employer reimburses you for vehicle expenses through an accountable plan, you can use that reimbursement tax-free, but you cannot also claim a deduction.

You Use the Standard Mileage Rate

If you're using the standard mileage rate (70 cents per mile for 2025), you generally cannot separately deduct car accessories. The rate is designed to cover all vehicle operating costs, including depreciation, maintenance, and incidental expenses.

Exception: Parking fees and tolls for business trips are separately deductible even under standard mileage.

The Accessory Is for Personal Comfort or Aesthetics

If the primary purpose is personal comfort, convenience, or aesthetics rather than business necessity, it's not deductible.

Examples:

• Premium seat covers for comfort
• Decorative dashboard accessories
• High-end sound systems (unless your business is audio-related)
• Vanity modifications

You Cannot Document the Business Purpose

Without documentation showing that the accessory serves a business purpose and tracking your business use percentage, claiming the deduction becomes difficult to defend if questioned.

How to Properly Document Car Accessory Deductions

If you plan to deduct car accessories under the actual expense method, follow these documentation practices:

1. Maintain a Mileage Log

The IRS expects contemporaneous records of business vehicle use. Your mileage log should include:

• Date of each business trip
• Starting and ending locations
• Business purpose of the trip
• Miles driven
• Total business miles vs. personal miles for the year

This percentage determines how much of your car accessory costs you can deduct.

2. Keep All Purchase Records

Save:

• Amazon order confirmation emails
• Receipts or invoices
• Credit card statements showing the charge

For services that analyze Amazon purchases, forwarding these confirmation emails can automatically create organized records.

3. Document Business Purpose

For each accessory purchase, write a brief explanation:

Example for dash cam: "Dash camera installed in business vehicle used for client visits and deliveries. Provides liability protection and documentation in case of accidents during business travel. Vehicle used 65% for business based on annual mileage log."

Example for toolbox: "Locking toolbox installed in pickup truck bed to securely transport business equipment to job sites. Vehicle used exclusively for contracting business (100% business use)."

4. Photograph Installation (for Expensive Items)

For accessories over a certain cost, consider taking photos of the installation. This provides evidence that:

• The accessory was actually purchased and installed
• It serves the stated business purpose
• It's proportionate to your business needs

5. Separate Business and Personal Expenses

If you buy multiple car accessories in a single Amazon order—some for business, some personal—separate them clearly in your records.

Example:

• Amazon Order #123-456789
  • Cargo organizer: $89 (business expense)
  • Phone mount: $25 (business expense)
  • Car air freshener: $8 (personal, not deductible)
  • Total business deduction: $114

Common Mistakes to Avoid

Deducting Accessories While Using Standard Mileage

If you're claiming the standard mileage rate, don't separately deduct car accessories (except parking and tolls). The standard rate already accounts for vehicle operating costs.

Exception: If you purchase a very expensive accessory that would be considered a capital improvement (like a lift kit or major commercial modification), you may need to depreciate it separately—consult a tax professional.

Not Tracking Business Use Percentage

If your vehicle is used for both business and personal purposes, you must calculate and apply the business use percentage. Deducting 100% of accessories on a mixed-use vehicle is incorrect and raises audit risk.

Deducting Personal Comfort Items

The IRS disallows expenses that primarily serve personal comfort rather than business necessity. A heated steering wheel cover is personal comfort. A hands-free phone mount for navigation is business necessity.

Missing Documentation

Claiming deductions without receipts, mileage logs, or business purpose documentation makes them difficult to defend if the IRS questions them.

Mixing Methods Incorrectly

You cannot use both standard mileage and actual expenses in the same year for the same vehicle. Choose one method and stick with it for that tax year.

Claiming Accessories for Vehicles Not Used in Business

If you buy car accessories on Amazon for a vehicle that's exclusively personal use, they're not deductible—even if you're self-employed and have other business vehicles.

How Purchase Deductions Can Help

Tracking car accessory purchases from Amazon for tax purposes can be time-consuming. Purchase Deductions simplifies this by:

• Automatically parsing Amazon order emails when you forward them to your unique email address
• Categorizing car accessories using the IRS Schedule C "Car and truck expenses" category
• Calculating business use percentages and deductible amounts based on your profile
• Generating business purpose documentation that explains why the accessory qualifies as a business expense
• Organizing records in an accountant-ready format

For example, if you forward an Amazon order confirmation for a $150 dash cam, the system might analyze it as:

• Category: Car and truck expenses (Schedule C Line 9)
• Business use percentage: 70% (based on your vehicle usage profile)
• Deductible amount: $105
• Business purpose: "Dash camera installed in business vehicle (70% business use) for liability protection and incident documentation during client visits, deliveries, and business travel."

FAQ: Car Accessories and Business Deductions

Can I deduct a GPS device if I use my phone for navigation instead?

If you purchase a standalone GPS device from Amazon and use it exclusively for business navigation (client visits, deliveries, service calls), it may be deductible under the actual expense method. However, if you use your smartphone for navigation instead, you would deduct the business portion of your phone costs separately, not as a car accessory.

What if I installed the accessory myself vs. paid for installation?

The deduction is for the cost of the accessory itself. If you paid for professional installation, that labor cost may also be deductible as part of the total expense. Self-installation doesn't affect the deductibility of the accessory purchase—you deduct the purchase price.

Do I need to depreciate expensive car accessories?

Most car accessories from Amazon are relatively inexpensive and can be deducted as current-year expenses. However, very expensive accessories or capital improvements (like a commercial vehicle upfit or lift system) may need to be depreciated over multiple years. Consult a tax professional for items over a certain cost threshold.

Can I deduct car accessories if I lease my vehicle instead of owning it?

Yes. If you lease a vehicle for business use and choose the actual expense method, you can deduct the business portion of car accessories, along with lease payments, insurance, gas, and maintenance.

What if I bought the accessory last year but installed it this year?

Generally, you deduct the expense in the year you purchased and placed the item in service for business use. If you bought it in 2024 but only installed and started using it for business in 2025, the deduction would typically apply to your 2025 tax return.

Are car cleaning supplies from Amazon deductible?

If you purchase car cleaning supplies (wash soap, microfiber towels, interior cleaner) to maintain a business vehicle, the business portion may be deductible under actual expenses. Keep in mind the business use percentage applies—if your vehicle is 50% business use, 50% of the cleaning supplies would be deductible.

Can ride-share drivers deduct phone chargers and mounts?

Yes, if you're a self-employed ride-share driver (Uber, Lyft), phone mounts and chargers used in your business vehicle may be deductible under the actual expense method, allocated by business use percentage. These are ordinary and necessary expenses for ride-share operations.

What about truck bed accessories for contractors?

Contractors who use pickup trucks for business can generally deduct truck bed accessories that serve a business purpose: toolboxes, bed liners, tonneau covers, ladder racks, etc. These are deductible under the actual expense method based on business use percentage.
