Can You Write Off Car Insurance? A Comprehensive Guide to Tax Deductions for Your Vehicle


As a car owner, you’re probably well aware of the numerous expenses that come with maintaining your vehicle, including car insurance premiums. While car insurance is a necessary expense, the good news is that in certain situations, you may be able to deduct a portion of your car insurance costs from your taxable income. In this article, we’ll explore the ins and outs of writing off car insurance, providing you with a clear understanding of when and how you can claim this deduction.

Understanding the Basics

Before we dive into the specifics, it’s essential to understand the fundamental principle behind tax deductions for car insurance. Generally, the Internal Revenue Service (IRS) allows you to deduct certain expenses related to the use of your vehicle for business purposes. However, if you’re using your car primarily for personal reasons, such as commuting to and from work or running errands, you cannot deduct your car insurance costs.

Qualifying for the Car Insurance Deduction

To qualify for the car insurance deduction, your vehicle must be used primarily for business purposes. This means that you must use your car for activities directly related to your trade or business, such as visiting clients, making sales calls, or transporting goods or equipment. If you use your car for both business and personal purposes, you’ll need to calculate the percentage of business use and deduct only that portion of your car insurance costs.

Calculating the Deduction

To calculate the deductible portion of your car insurance costs, you’ll need to keep meticulous records of your vehicle’s business and personal mileage. The IRS requires you to maintain a detailed mileage log, which should include the following information:

  • Date of each trip
  • Destination and purpose of each trip
  • Odometer readings at the beginning and end of each trip
  • Total miles driven for business and personal purposes

Once you have this information, you can calculate the percentage of business use by dividing your business miles by your total miles driven for the year. This percentage will determine the portion of your car insurance costs that you can deduct.

For example, if you drove 15,000 miles for the year, with 10,000 miles being for business purposes, your business use percentage would be 66.67% (10,000 miles / 15,000 miles). If your annual car insurance premium was $1,200, you could deduct $800 (66.67% of $1,200) as a business expense.

Other Deductible Car Expenses

In addition to car insurance, you may also be able to deduct other expenses related to the business use of your vehicle, such as:

  • Gasoline and oil
  • Repairs and maintenance
  • Registration fees
  • Tolls and parking fees
  • Lease payments (if you lease your vehicle for business purposes)
  • Depreciation (if you own your vehicle and use it for business purposes)

It’s important to note that these deductions are subject to certain limitations and restrictions, so it’s always advisable to consult with a tax professional or refer to the IRS guidelines for the most up-to-date information.

Recordkeeping and Documentation

Proper recordkeeping and documentation are crucial when claiming car insurance and other vehicle-related deductions. The IRS requires you to maintain accurate records and receipts to support your deductions in case of an audit. Failure to provide adequate documentation can result in the disallowance of your deductions, potentially leading to additional taxes, penalties, and interest.

Here are some tips for keeping accurate records:

  • Use a mileage log or app to track your business and personal mileage
  • Keep receipts for all car-related expenses, including insurance premiums, repairs, and fuel purchases
  • Maintain a separate bank account or credit card for business-related expenses to simplify record-keeping
  • Take photographs or videos of your vehicle being used for business purposes as additional documentation


Writing off car insurance and other vehicle-related expenses can provide valuable tax savings for individuals who use their cars for business purposes. However, it’s essential to understand the qualifying criteria and keep meticulous records to ensure compliance with IRS regulations. By following the guidelines outlined in this article and consulting with a tax professional when necessary, you can maximize your deductions and potentially reduce your overall tax burden.

Can you write off auto insurance? Deductions on your taxes


Can I use my car insurance as a tax deduction?

If you use your car strictly for personal use, you likely cannot deduct your car insurance costs on your tax return. Unless you use your car for business-related purposes, you are likely ineligible to claim your auto insurance premium on your tax return.

What percentage of my car insurance can I write-off?

If you drive a car for both personal and business reasons, you may deduct your insurance costs from your taxes for the percentage of the time you use your car for business. If half the time you use your car for business, then you may deduct 50% of the yearly auto insurance costs on your taxes.

How much insurance can I write-off?

You can usually deduct the premiums for short-term health insurance as a medical expense. Short-term health insurance premiums are paid out-of-pocket using pre-tax dollars, so if you take the itemized deduction and your total annual medical expenses are greater than 7.5% of your AGI, you can claim the deduction.

Can I write-off car insurance for my business?

If you use a car for business-related purposes (other than as an employee), many expenses associated with that vehicle may be tax deductible as business expenses, including your auto insurance premiums.
