Add each business trip with its date, purpose and either the start and end odometer readings or the miles driven. The calculator applies the IRS business standard mileage rate for each trip's date and totals everything. You can edit the rates.
Not tax advice. This tool does arithmetic on the numbers you enter. Whether a trip or payment counts, which rate or threshold applies, and how to report it depend on your situation. Check with a tax professional or the IRS pages linked here.
