Common questions about the vehicle standard mileage rate vs. actual expenses (1120-S/1065)

SOLVEDby IntuitLacerte Tax60Updated August 11, 2021

Where do I enter vehicle mileage information in the program?

You can enter Total, Business, and Commuting mileage in each module's Depreciation screen of Lacerte.

How is the mileage information used for each module?

  • In the Individual module, the mileage is used to compute the business use percentage for the vehicle via Form 4562, and a taxpayer can take the vehicle's actual expenses / standard mileage rate as an expense/deduction via Form 2106 or Form 2106-EZ.
  • In the business modules, the mileage is used only to calculate Business Use percentage on Form 4562, which is then applied to the current year depreciation.
    • That amount is then carried to the form that's linked to the asset (1065, 1120-S, 8825, 4562) as depreciation.

Can the standard mileage rate be used for partnerships or S corporations?

There's no direct mention of the standard mileage rate being allowed as an expense/deduction on a business return. Per the IRS Instructions for Form 4562:

  • If you're an employee deducting job-related vehicle expenses using either the standard mileage rate or actual expenses, use Form 2106, Employee Business Expenses, or Form 2106-EZ, Unreimbursed Employee Business Expenses, for this purpose.

Since Form 2106 isn't available in the S-Corporate or Partnership modules, the standard mileage rate or actual expenses for a vehicle won't be automatically calculated based on input in the Depreciation screen.
