Can an S Corporation Deduct Vehicle Expenses?

An S corporation can own a vehicle or reimburse shareholder business use, but personal use and strict substantiation must be handled.

How it works

The rule, and what it turns on.

Company-owned vehicle personal use can create taxable fringe-benefit income. Personally owned vehicle expenses can often be reimbursed through an accountable plan.

Example

Company pickup is 80% business/20% personal by mileage; personal-use value generally needs payroll treatment.

Common mistakes

What we see go wrong, and what we do instead.

  • No mileage log.
  • Ignoring personal use.

A better approach

  • Consider accountable-plan reimbursement for personally owned vehicles.

Authority

Where this comes from, so you can check it.

IRC §§162 and 274(d); Treas. Reg. §1.274-5T; IRS Publication 463; current IRS standard mileage guidance.
