What Is a Mileage Log?
A mileage log is a record that tracks driving distances for work-related activities. It is the definitive proof used to validate tax deductions or employer reimbursements. Without a log, the IRS (or your boss) can deny your claim.
Why Use a Google Sheets Mileage Log?
The days of keeping a pen-and-paper notebook in your glovebox are over. Here is why switching to a digital spreadsheet is superior:
- Cloud Backup: You can never lose your log. Even if you lose your phone, your data is safe in the cloud.
- Instant Accessibility: You can update your log from your phone immediately after a trip, ensuring you don’t forget details.
- Audit Protection: Handwritten logs are often illegible or incomplete. A clean, printed spreadsheet provides the concrete evidence the IRS requires during an audit.
IRS Requirements: What to Track
To ensure your log is “Audit-Proof,” the IRS requires specific data points for every single trip. If you leave these out, your deduction could be disqualified.
| Requirement | Description |
|---|---|
| Date | The specific day the trip occurred. |
| Mileage | Total miles driven (Start/End odometer readings are recommended). |
| Destination | Where you went (City, Client Office, Job Site). |
| Business Purpose | Why you went there (e.g., “Client Meeting,” “Supply Run”). |
What Driving is Deductible?
Not every mile counts. Here is the general rule of thumb:
- Deductible: Driving from your office to a client, driving between job sites, or driving to buy supplies.
- Not Deductible: Your commute. Driving from your home to your regular place of work is never deductible.
How to Create a Mileage Tracking Spreadsheet (DIY Guide)
If you prefer to build your own tracker to customize it fully, follow these steps.
Step 1: Set Up Your Columns
Open a new Google Sheet and create the following headers in Row 1:
- Date
- Trip Purpose
- Start Odometer
- End Odometer
- Total Miles (Formula)
- Reimbursement Rate (Optional)
- Total Value (Optional)
Step 2: Add Visual Formatting
To make the sheet easier to read:
- Highlight your header row.
- Click the Bold icon (B).
- Add a bottom border to separate headers from data.
- (Optional) Use “Alternating Colors” in the Format menu to make rows easier to scan.
Step 3: The Formulas
Automation is the best part of a digital log. Here are the three formulas you need to make the sheet calculate itself.
1. Calculate Miles Per Trip
In your “Total Miles” column, you want to subtract the starting odometer from the ending odometer.
=F8-E8
(Assuming E8 is your Start Odometer and F8 is your End Odometer).
2. Calculate Total Miles Traveled (Year-to-Date)
To see how many miles you have driven all year, use the SUM function at the bottom or top of your sheet.
=SUM(G8:G100)
3. Calculate Reimbursement Value
If you are being paid a specific rate (e.g., $0.67 per mile), use this multiplication formula:
=G8*0.67
Replace 0.67 with your specific reimbursement rate.
Frequently Asked Questions
Does Google Sheets have a built-in mileage tracker?
No, Google Sheets does not come with a native mileage tracking template. You must either build one from scratch or download a third-party template like the ones provided above.
Do I need to record odometer readings?
While you can just record “15 miles,” the IRS strongly prefers odometer readings (Start: 10,000 / End: 10,015). This provides a continuous chain of evidence that proves the car was actually driven those distances.
How do I use this on my phone?
Simply download the Google Sheets app (iOS or Android). Log into your Google account, and you can open this template directly on your phone. Many users add a shortcut to the specific sheet on their home screen for quick access.
