Do I have to use the IRS standard rate?

No — you can instead deduct actual vehicle expenses (gas, insurance, oil changes, tires, depreciation). The standard rate is simpler; actual expenses may be higher for expensive vehicles. You must choose one method and generally can't switch in the same tax year.

Does my employer have to reimburse my mileage?

Federally, employers don't have to reimburse at the IRS rate — they just can't let reimbursements below IRS rate reduce employees below minimum wage. California, Massachusetts, and Illinois have laws requiring reimbursement. Check your state.

What records does the IRS require for mileage?

A contemporaneous mileage log recording: date, destination, business purpose, and miles driven for each trip. Reconstructed logs from memory are generally not accepted if audited. Apps like MileIQ, Everlance, or Stride automate GPS tracking.

Can I deduct commuting miles?

No — the IRS considers commuting (home to regular workplace and back) a personal expense, not deductible. Business miles start once you arrive at your first work location or travel between job sites.
