Why a Daily Mileage Log is Crucial for Your Finances
Keeping a mileage log isn’t just a suggestion; it’s a requirement from the IRS if you want to claim vehicle-related business expenses. Without proper documentation, you risk losing thousands in deductions and facing hassles during an audit.
The Power of Proper Documentation
For starters, the IRS mandates specific details for every business trip you claim. This includes the date, the destination, the business purpose of the trip, and the total miles driven. Additionally, your information, your vehicle’s information, and your starting and ending odometer readings for the year. Sounds like a lot, right? Well, it is, but it pays off significantly. Without a log, you leave money on the table.
Avoiding Audit Woes
Beyond the financial benefits, a robust contemporaneous mileage log offers peace of mind. The IRS does conduct audits, and one of the first things they’ll ask for is your mileage records if you’ve claimed car expenses. A well-maintained log demonstrates diligence and compliance, significantly reducing your audit risk. Watch this video for a visual explanation of the importance of contemporaneous mileage logs.
Who Benefits Most from a Daily Mileage Log?
If you fall into any of these categories and you drive around for work, a meticulous contemporaneous mileage log is non-negotiable:
- Self-Employed Professionals: Consultants, real estate agents, direct sellers.
- Small Business Owners: Delivery services, contractors, mobile service providers.
- Gig Economy Workers: Rideshare drivers, food delivery personnel, couriers.
- Employees Seeking Reimbursement: Sales professionals, field technicians.
Contemporaneous vs. Monthly Mileage Log
The IRS strongly prefers contemporaneous logging, meaning you record your mileage at the time of the trip or very soon after. This is because memories fade, and estimates are a red flag for auditors. While you can technically log monthly, it’s far riskier. Digital solutions make contemporaneous logging effortless, automatically tracking your trips as you drive.
How to Set Up Your Daily Mileage Log for Success
Setting up your mileage log doesn’t have to be complicated. Whether you prefer pen and paper or digital solutions, the key is consistency and attention to detail.

Customer Story: How MileageWise Saved Me $1,000s
I’m a freelance caterer. My car is my office on wheels. I drove daily to venues, supply runs, errands, you name it. For years, I took my daily mileage log lightly. Then tax season would come around, and I’d spend hours trying to reconstruct everything and still feel like I was losing money. Even worse, a photographer I know once got audited over an inconsistent log. Yikes. Then a friend told me about MileageWise. I was skeptical. Another app, another subscription… But the lifetime plan won me over. The setup was easy, and now it auto-tracks my drives and even categorizes my trips. Last tax season? I tapped “generate report” and got a clean, IRS-compliant log. The app logged over 8,000 more miles than I ever did before. I thought these tools were for big businesses, but it turns out, even creatives like me need them too.

FAQ
Can I use a mileage tracking app instead of a paper log?
Yes. The IRS accepts digital mileage logs as long as they contain all required details and are backed up. Popular apps include Everlance, MileIQ, and MileageWise, which automatically record trips and generate compliant logs.
Are there free templates available for daily mileage logs?
Yes. You can find free daily mileage log templates as downloads for Excel, Google Sheets, or printable PDFs. Microsoft Office, Google Docs template gallery, various accounting sites, and this blog offer ready-to-use templates.
Can I claim mileage for commuting to my regular workplace?
No. Commuting mileage (the distance from home to a regular place of work) is NOT deductible according to IRS rules. Only business-related travel away from your regular workplace is eligible.
Is a daily mileage log better than a monthly mileage log?
Yes, a daily mileage log is better because it’s more accurate for proving business use. Monthly mileage logs risk missing trips or details, while daily entries help create a clear, contemporaneous record.
Can I edit or recreate a mileage log at the end of the year if I forgot to keep one?
Reconstructing a log from memory or using estimates is not recommended and may not hold up in an audit. However, if you do end up without a mileage log, MileageWise offers a range of solutions for retroactive mileage logging.
