How the standard mileage rate works
The IRS sets separate cents-per-mile rates each year for business, medical/moving, and charitable driving. Multiply each mileage category by its rate and sum the results — no receipts required, just a mileage log with dates and purposes.
Standard mileage vs actual expenses
Actual expenses let you deduct a business-use percentage of gas, insurance, repairs, and depreciation, which can beat the standard rate for expensive or heavily used vehicles, but require meticulous receipt-keeping and lock you out of switching methods in later years for leased vehicles.
Why tax bracket matters for cash savings
The deduction itself only reduces taxable income, not tax owed directly. Multiplying the deduction by your marginal tax bracket estimates the actual cash you keep, which is the number that matters when deciding if extra mileage tracking effort is worthwhile.
Keeping a compliant mileage log
The IRS requires contemporaneous records showing date, destination, business purpose, and miles for every trip claimed. Apps that auto-track GPS mileage make this far easier than reconstructing a year of driving at tax time.

People also ask
Can I switch between standard mileage and actual expenses each year?
Only if you used the standard rate the first year you placed the vehicle in service; after that you may alternate freely, but claiming actual expenses (or depreciation) first locks you into that method for the vehicle's life.
Does the standard rate include gas?
Yes, the business rate is meant to cover fuel, maintenance, insurance, and depreciation combined, so you cannot deduct gas separately on top of it.
Are commuting miles deductible?
No, regular commuting between home and your main workplace is never deductible under either method — only business-purpose driving beyond normal commuting counts.
What counts as medical mileage?
Driving to and from medical appointments, pharmacies, and treatment for yourself or dependents, deductible only to the extent your total medical expenses exceed the IRS AGI threshold.
Can self-employed and W-2 employees both claim this?
Self-employed filers can claim business mileage on Schedule C; W-2 employees generally cannot deduct unreimbursed mileage federally after the 2018 tax law changes, though some states still allow it.
How do parking and tolls factor in?
Parking fees and tolls are deductible in addition to the standard mileage rate — they are not included in the per-mile rate.
Is charitable mileage worth tracking?
At $0.14/mile it's modest, but volunteers who drive frequently for a charity can still accumulate a meaningful itemized deduction over a year.
What if I use my car for both business and personal use?
Only log and claim the business-use miles; keep an odometer log showing total annual miles and business miles to calculate your business-use percentage accurately.
Do I need a separate log for each mileage category?
It's best practice to track business, medical, and charitable trips separately since each is deducted differently and audited under different rules.
Why is actual expenses sometimes better for luxury or work trucks?
Vehicles with high purchase price, financing costs, or heavy repair bills often generate a larger deduction under actual expenses plus depreciation than the flat per-mile rate allows.
