Quick Answer
Yes, you can reconstruct missing mileage logs using available records like app data, bank statements, and calendar entries. The IRS allows reconstructed records if they're reasonable and based on documented evidence. For 2026, each business mile saves you about 67 cents at the standard mileage rate (67 cents × your tax bracket).

Can you reconstruct missing mileage logs?
Yes, the IRS allows you to reconstruct missing mileage records, but you need to base them on available documentation and reasonable estimates. According to IRS Publication 463, you can use "other evidence" to support your deductions when complete records aren't available.
How to reconstruct rideshare/delivery mileage
Start with your platform data. Most rideshare and delivery apps provide annual summaries:
These summaries typically show total miles driven while working, but they only count miles with passengers or deliveries — not the miles driving to pickup locations or between rides.
Example reconstruction for a DoorDash driver
Let's say your DoorDash summary shows 8,000 delivery miles for 2026, but you know you drove additional miles:
Supporting documentation you can use
Bank and credit card statements
Phone and app data
Vehicle records
Step-by-step reconstruction method
Step 1: Calculate your total vehicle miles for the year
Step 2: Estimate business vs. personal split
Step 3: Reality-check your estimate
What the IRS accepts as "reasonable"
Red flags to avoid
What you should do
1. Gather all available records from apps, banks, and vehicle maintenance
2. Use our deduction-finder tool to identify platform-specific data sources
3. Create a detailed reconstruction spreadsheet with dates and sources
4. Log current mileage going forward to establish baseline patterns
5. Keep digital copies of all supporting documentation
Key takeaway: You can legally reconstruct missing mileage logs using platform data, bank records, and reasonable estimates. Most rideshare drivers can recover 15,000-25,000 deductible miles worth $10,000-16,750 in deductions.
