- What is the 2026 IRS standard mileage rate for business?
- The IRS announced 70 cents per mile ($0.70/mile) for business driving in 2026, up from 67¢ in 2024. This rate covers the cost of fuel, depreciation, insurance, and maintenance. You multiply your total business miles by 0.70 to get the deductible or reimbursable amount. The rates for medical/moving (21¢) and charitable (14¢) travel are separate and lower. Always verify the current rate at IRS.gov before filing — rates can be updated mid-year.
- What records does the IRS require for a mileage deduction?
- Under IRC §274(d), the IRS requires a contemporaneous mileage log that records (1) the date of each trip, (2) the destination (city or address), (3) the business purpose, and (4) the number of miles driven. "Contemporaneous" means recorded at or near the time of the trip — not reconstructed months later from memory. This tool generates a log with all four required fields. Keep the log (PDF or CSV) with your tax records for at least three years after the return due date.
- Can I use GPS coordinates instead of addresses?
- Yes — the IRS does not require street addresses, only sufficient information to identify the destination. GPS latitude/longitude coordinates satisfy this. Click the GPS Start or GPS End buttons to stamp your current location. The Haversine calculation then gives a straight-line distance; if your actual driven route is longer, use the manual miles override to enter the odometer or map distance, which is what the IRS actually requires (total miles driven, not straight-line distance).
- Is this tool IRS-compliant?
- This calculator produces a mileage log that satisfies the four content requirements of IRC §274(d) and the contemporaneous record-keeping standard of Rev. Proc. 98-25. The PDF export includes date, origin, destination, business purpose, miles, and reimbursement amount in columnar form that accountants and auditors expect. However, this tool is not tax advice — consult a CPA or tax professional to confirm your specific situation qualifies for the business mileage deduction.
- Does my data get sent to any server?
- No. All trip data is stored exclusively in your browser's IndexedDB — a local database on your own device. The PDF is generated client-side using the pdf-lib library loaded from a CDN. No trip details, GPS coordinates, or personal information are ever transmitted to Knackpad's servers or any third party.
