The standard method trades detail for a rate
Multiply substantiated business miles by the official rate for the applicable period. That rate represents depreciation and ordinary operating costs, so most vehicle costs are not added again.
Parking and toll treatment can be separate in appropriate circumstances; this v1 comparison focuses on core vehicle costs.
The actual method needs allocation
Add eligible actual costs, then multiply by a defensible business-use percentage. Purchase price, depreciation, lease rules, and disposition can require more detailed tax treatment than a simple annual total.
Keep receipts and mileage even under the actual method because business-use allocation still matters.
The larger number is not the whole decision
Eligibility, first-year method choices, owned versus leased vehicles, depreciation recapture, and future switching rules can matter. The calculator compares arithmetic, not those legal constraints.
Use the result as a question to bring to your tax professional or current IRS instructions.
Frequently asked questions
Can I switch methods every year?
Not always. Switching rules differ for owned and leased vehicles and can depend on the first method used. Review current IRS guidance before relying on the larger estimate.
What expenses go into the actual method?
Common categories include fuel, insurance, repairs, maintenance, registration, lease costs, and depreciation, allocated to business use as applicable. Specific eligibility varies.
Do I still need mileage records with actual expenses?
Yes. Mileage is a common way to substantiate and allocate vehicle business use even when claiming actual costs.
Can I add parking and tolls to standard mileage?
Business parking and tolls may be separately deductible in appropriate circumstances. This v1 comparison excludes them from both sides to keep the vehicle-method comparison consistent.
Which method saves more tax?
The method with the larger eligible deduction may reduce modeled profit more, but the tax effect depends on your complete return and legal eligibility. A larger deduction is not a cash reimbursement.
