Can my company reimburse mileage if I also use the car personally?

The direct answer

Business miles can potentially be reimbursed when adequately documented; personal use does not make every mile deductible. Separate qualifying business travel from commuting and personal trips. Apply the relevant year's method and avoid combining incompatible vehicle expense treatments.

A practical example

Illustrative example, not a client result: A contractor drives from a jobsite to a supplier and later to a personal appointment. The mileage log should distinguish those legs.

Begin with the underlying business purpose

An expense policy is a recordkeeping process, not a new category of deductible spending. Identify the business purpose and any personal component first, then select the appropriate reimbursement and reporting treatment. Keep payment records connected to itemized support, and assign responsibility for reviewing expense reports so mistakes do not accumulate until annual filing.

Put the answer into your own tax file

Start by identifying the taxpayer, the tax year and the actual transaction. Then connect the transaction to the original documents before choosing a return line or moving money between accounts. A payment description can be useful evidence, but it cannot replace the underlying facts.

The records to review for this topic are: Itemized receipts, business-purpose notes, travel itineraries, mileage logs and the reimbursement policy.

For the example above, write down the decision that needs to be made, the missing information and the person responsible for supplying it. Keep the business, payroll, property and personal return teams aligned when more than one set of records is affected.
