Business Vehicle Tax Organizer

Gather mileage logs, purchase documents, operating expenses, loan interest and sale or trade details before completing the tool below. Enter actual records and verify the tax year and business-use period. This organizer prepares information for a tax discussion; it does not choose your deduction method or establish eligibility.

Example and next steps

A vehicle driven 15,000 total miles, including 10,000 qualified business miles, has a mileage-based business-use ratio of about 66.7%. The ratio alone is not a deduction. Keep trip dates, destinations and business purposes, and separate commuting and personal travel. For depreciation estimates, use the vehicle depreciation calculator. We can help apply the records through tax planning and preparation.

What records should I gather?

Gather a mileage log, purchase or lease documents, receipts for operating costs, financing details and any sale or trade records. Keep the business purpose and dates of trips.

Does commuting count as business mileage?

Travel between home and a regular workplace is generally commuting. Special circumstances can change the treatment; review the IRS Publication 463 guidance with your CPA.

Does the organizer choose a deduction method?

No. It organizes information for comparing applicable methods and reviewing depreciation. The right method depends on eligibility, prior elections, vehicle use and your records.

Can I use the result directly on my tax return?

Have your CPA review the underlying records and applicable rules first. An organized summary or calculator estimate does not establish a deductible amount.
