What Actually Counts as Business Driving
As a freelance graphic designer, the IRS lets you deduct car expenses only for business use, not personal use. Business use means driving to meet a client, pick up printed proofs, scout a location for a photo shoot, attend a portfolio review, or drive to a coworking space you rent for client work. It does not include your regular commute from home to a home office you use every day, since that's considered personal, not business, mileage under IRS rules.
If you have a dedicated home office that qualifies as your principal place of business (this matters for the home office deduction too), trips from that home office to a client site or supply store count as business miles from the very first mile. That's one reason setting up a proper home office matters beyond just the home office deduction itself.
Two Ways to Calculate the Write-Off
You have two methods, and you pick one for the year (with some restrictions on switching later):
Standard mileage rate. You track total business miles driven for the year and multiply by the IRS standard mileage rate, which changes annually (check the current year's rate before filing). This method is simpler: no receipts for gas, oil changes, or repairs needed, just a mileage log.
Actual expense method. You total up everything: gas, insurance, repairs, depreciation, lease payments, registration fees, then multiply by the percentage of miles driven for business. If you drove 8,000 miles for business out of 20,000 total miles, you deduct 40% of your actual car costs. This method requires more recordkeeping but can produce a bigger deduction if you have a newer, more expensive vehicle or high repair costs.
Most freelance designers use the standard mileage rate because it's far less paperwork, especially if a home printer and a laptop are really your main business tools and the car is just for occasional runs.
What You Need to Track and Where It Goes
Regardless of method, the IRS wants a mileage log: date, destination, business purpose, and miles driven for each trip. Apps that auto-track GPS mileage make this painless; a paper notebook in the glove box works too, just be consistent. Without a log, this deduction is one of the first things an auditor questions, since it's easy to overstate.
The deduction itself goes on Schedule C, the form freelancers use to report business income and expenses, specifically in the car and truck expenses line. It reduces your net self-employment income, which in turn lowers both your income tax and your 15.3% self-employment tax bill (Social Security and Medicare combined) reported on Schedule SE.
One more detail: if you use the standard mileage rate, you cannot separately deduct gas or repairs, since those costs are baked into the per-mile rate. Parking fees and tolls for business trips are deductible on top of either method though, so keep those receipts too.
