Gas, insurance, maintenance, depreciation, etc. — we'll compare this to the standard mileage amount and use whichever is more advantageous.

Leg A — Home → First Business Location

Commute — not accountable-plan eligible. Always excluded from the reimbursable total.

Leg B — Business Location → Business Location

Deductible and reimbursable — every location-to-location leg between the first and last stop of the day qualifies.

Leg C — Last Business Location → Home

Commute — not accountable-plan eligible. Always excluded from the reimbursable total.

Leg A and Leg C (commute) miles are shown in your results but excluded from the tax-free reimbursement total. Reimbursing commute miles tax-free is not allowed under an accountable plan — if you want to pay them, it must go through payroll as ordinary taxable compensation.
