IRS Schedule C Part IV Vehicle Information Worksheet Generator (2026 Tax Year)
If your car moved 16,000 miles in 2026, the business, commuting and other columns must add to 16,000. This worksheet flags a mismatch before you hand the figures to a preparer.
Schedule C Part IV asks for the date the vehicle was placed in service, business, commuting and other miles, personal availability, another available vehicle and written evidence. This page checks the mileage reconciliation only; complete the remaining questions on the actual form.
The IRS rate table gives the cents-per-mile amounts. It does not decide whether a particular drive is deductible. Write down why the drive happened before relying on any calculation.
How this worksheet works
Subtract the starting odometer from the ending odometer. The three mileage categories should match that total. If they do not, inspect your source records instead of forcing the numbers to fit.
Worked example
Annual change
16,000 mi
Business + commute + other
10,000 + 3,000 + 3,000
Keep the records behind the number
Keep service receipts or odometer photos and a trip-level business log. Review the tax-year form instructions because line numbers and filing conditions can change. Some filers must also use Form 4562.
72.5 cents per business mile for January 1 through June 30, 2026; 76 cents for July 1 through December 31, 2026.

Milevaro reports are records of trips logged by the user. They are not IRS-certified and do not guarantee a tax deduction. A deduction lowers taxable income; it is not direct cash back. The estimated deduction is business miles multiplied by a user-set rate and is an estimate, not tax advice. Consult a qualified tax professional.
