If your home qualifies as your principal place of business, the drive from your front door to a client site is deductible business mileage, not nondeductible commuting. This guide explains the federal test that flips that switch, compares the standard mileage rate against the actual expense method with a full worked example at 2026 rates, and lays out the records the IRS expects you to keep. All figures and rules below are U.S. federal rules for self-employed filers reporting on Schedule C; state income tax treatment can differ, and that is covered near the end.
Why the Home Office Test Decides Everything
Commuting is the single largest category of miles that self-employed people wrongly deduct, and the reason is that the rule has an exception most people never read. The general federal rule is that the cost of getting between your residence and your place of business is a personal expense with no deduction attached to it, no matter how far you drive or how early you leave.
The exception is narrow and specific. If your residence is your principal place of business, then trips between that residence and another work location in the same trade or business are deductible transportation expenses. Once the home office qualifies, the first trip of the day stops being a commute, because you have already arrived at work before you get in the car.
There is a second, separate route to deducting some of these trips. If you have a regular place of business away from your home, daily trips between your residence and a temporary work location in the same trade are deductible. The IRS treats work expected to last one year or less as temporary, absent facts pointing the other way. This route matters for contractors with a leased workspace, but for a genuine remote worker the home office test is the one that does the work.
The two-part principal place of business test. Your home office qualifies as your principal place of business if you meet all of the following:
- Exclusive use. The space is used only for your trade or business. A desk in the corner of a bedroom can qualify; a dining table you also eat at cannot.
- Regular use. You use the space on a continuing basis, not occasionally or incidentally.
- Administrative or management activities. You use it for the administrative or management side of the business, such as billing clients, keeping books and records, ordering supplies, and setting appointments.
- No other fixed location. You have no other fixed location where you conduct substantial administrative or management activities for that same business.
That last point is what trips up hybrid workers. If you also rent a small studio where you do your invoicing and scheduling, the studio is likely your principal place of business, and the drive there each morning is a commute.
Which trips count once the office qualifies. With a qualifying home office, the following are deductible business miles:
- Home to a client’s or customer’s place of business, and the return trip.
- Home to a job site, a coworking space rented for a specific project, or a temporary work location.
- Travel between two client locations on the same day.
- Trips to the bank, post office, or a supply store when the purpose is business.
- Home to a conference, trade show, or continuing education event tied to your business.
These stay nondeductible regardless:
- Personal errands folded into a business trip, for the personal portion of the mileage.
- Trips to your own second workspace if that workspace, not your home, is your principal place of business.
- Meals out or gym visits on the way back from a client, for the detour portion.
How the Standard Mileage Rate Works
The standard mileage rate is a single per-mile figure that stands in for gas, oil, repairs, tires, insurance, registration, and depreciation. You multiply business miles by the rate and you are done. You do not track fuel receipts or calculate depreciation schedules, but you also cannot deduct those costs separately on top of the rate.
For the 2026 tax year the business standard mileage rate changed mid-year. It is 72.5 cents per mile for miles driven from January 1, 2026 through June 30, 2026, and 76 cents per mile for miles driven from July 1, 2026 through December 31, 2026. The mid-year increase was tied to fuel price movement. For the 2025 tax year the rate was a flat 70 cents per mile for the full year. Because the rate is reset annually and can be revised mid-year, always confirm the figure for the year you are actually filing.
Two eligibility rules apply to owned vehicles:
- You must elect the standard mileage rate in the first year the vehicle is available for business use. If you claim actual expenses with accelerated depreciation in year one, that vehicle is locked out of the standard mileage rate permanently.
- You cannot use it after claiming a Section 179 deduction, the special depreciation allowance, or accelerated (non-straight-line) MACRS depreciation on that vehicle.
For a leased vehicle, the rule is stricter in the other direction. If you choose the standard mileage rate for a leased car, you must use it for the entire lease period, including renewals.
One more restriction catches growing businesses: you cannot use the standard mileage rate if you operate five or more cars at the same time, as in a fleet operation.
How the Actual Expense Method Works
The actual expense method totals what the vehicle genuinely cost you for the year, then deducts the business-use percentage of that total. Business-use percentage is business miles divided by total miles driven, so you still need a mileage log even when you choose this method.
Deductible actual expenses include gas and oil, repairs and maintenance, tires, insurance, registration and license fees, garage rent, and either depreciation on an owned vehicle or the deductible portion of lease payments. Loan interest on a vehicle financed for business use is deductible for the self-employed, though the principal portion of the payment is not; the vehicle’s cost is recovered through depreciation instead.
Actual expenses tend to win when the vehicle is expensive to own relative to how far it goes: a newer or heavier vehicle, high insurance premiums, a bad repair year, or low annual mileage spread over high fixed costs. The standard mileage rate tends to win when you drive a lot of business miles in a paid-off, inexpensive, fuel-efficient car.
The depreciation consequence nobody warns you about. The standard mileage rate has a depreciation component baked into it, and that component reduces your vehicle’s tax basis exactly as if you had claimed depreciation directly. For the 2026 tax year the portion of the business standard mileage rate treated as depreciation is 35 cents per mile. For 2025 it was 33 cents per mile.
This matters when you sell or trade the vehicle. Twelve thousand business miles in 2026 reduces basis by $4,200 whether you noticed it or not, which can turn an apparently break-even sale into a taxable gain. Track cumulative basis reduction from year one.
Side-by-Side Calculation at 2026 Rates
The scenario below is a self-employed consultant with a qualifying home office who drove 18,000 total miles in 2026, of which 12,000 were business miles, split evenly across the two rate periods. Business-use percentage is 66.67 percent.
| Line item | Standard mileage rate | Actual expense method |
|---|---|---|
| Business miles, Jan 1 to Jun 30, 2026 | 6,000 miles at $0.725 = $4,350 | Included in totals below |
| Business miles, Jul 1 to Dec 31, 2026 | 6,000 miles at $0.760 = $4,560 | Included in totals below |
| Gasoline (full year, all miles) | Included in rate | $3,200 |
| Insurance | Included in rate | $1,700 |
| Repairs and maintenance | Included in rate | $950 |
| Tires | Included in rate | $600 |
| Registration and license fees | Included in rate | $250 |
| Depreciation | Included in rate | $4,000 |
| Total vehicle costs before allocation | n/a | $10,700 |
| Business-use allocation (66.67%) | n/a | $7,133 |
| Business parking and tolls (deductible under both methods) | $300 | $300 |
| Total vehicle deduction | $9,210 | $7,433 |
In this scenario the standard mileage rate produces $1,777 more in deductions. Reverse the assumptions, say 4,000 business miles in a vehicle with $2,600 in insurance and a $7,000 first-year depreciation figure, and the actual expense method wins comfortably. The only way to know is to compute both, which is why the mileage log is required either way.
Note that business parking fees and tolls are deductible in addition to the standard mileage rate. Parking at your own main place of business, and tolls incurred on a genuine commute, are personal expenses and are not deductible.
Records the IRS Expects You to Keep
Vehicle expenses fall under the strict substantiation rules, which means a reasonable estimate at filing time is not enough. You must substantiate expenses with adequate records or with sufficient evidence supporting your own statement.
For every business trip, record:
- Date of the trip.
- Mileage driven for that trip.
- Destination, including the client or location name.
- Business purpose, stated specifically enough that a stranger could follow it. “Client meeting, Acme Corp, contract review” works. “Business” does not.
Alongside the trip log, keep:
- Odometer readings at the start and end of the tax year, which establish total miles and therefore your business-use percentage.
- Receipts for actual expenses if you use that method, plus repair invoices and insurance statements.
- Purchase documentation for the vehicle, which sets your depreciation basis.
Records should be kept contemporaneously, meaning at or near the time of the trip rather than reconstructed months later. A weekly habit of writing up the log is generally accepted; a single spreadsheet built the night before you file is the pattern that draws scrutiny. Any format works, including a paper notebook, a spreadsheet, or a GPS mileage app, as long as it captures the four elements above.
Self-employed filers report vehicle expenses on Schedule C. Because the 2026 rate changed mid-year, keep your log in a form that lets you separate miles driven before July 1, 2026 from miles driven on or after that date.
Mistakes and Exceptions That Cost Remote Workers Money
Deducting the first trip without a qualifying home office. This is the most expensive error in the category. If your workspace fails the exclusive-use requirement, the home office deduction disappears and every home-to-client trip reverts to nondeductible commuting.
Locking yourself out of the standard mileage rate in year one. Claiming Section 179 or bonus depreciation on a new vehicle in its first business year feels like a win, and it may be, but it permanently forecloses the standard mileage rate for that vehicle. Model both paths across several years before deciding.
Assuming you can freely switch methods. For an owned vehicle where you properly elected the standard mileage rate in year one, you may switch to actual expenses in a later year, but you must then use straight-line depreciation for the remaining useful life. For a leased vehicle, choosing the standard mileage rate binds you for the entire lease.
Applying one rate to the whole 2026 year. Using 72.5 cents for December miles understates the deduction; using 76 cents for February miles overstates it. Split the log at July 1, 2026.
Ignoring the basis reduction. Every mile deducted at the standard rate quietly lowers what the vehicle is worth for tax purposes on sale.
Mixing personal errands into business trips. Only the business portion of a mixed trip is deductible. Log the detour honestly.
State Rules Are a Separate Question
Everything above is federal. Most states that levy an income tax start from federal figures, so a Schedule C vehicle deduction usually carries through, but conformity is not universal and some states decouple from specific federal depreciation provisions, including bonus depreciation and Section 179 limits. A handful of states also maintain their own reimbursement rules for workers, which are a different legal question from the deduction rules here. Worker classification, whether you are genuinely an independent contractor rather than an employee, is also determined partly by state law and can vary sharply between states.
Confirm your federal numbers against the current IRS mileage rate notice and Publication 463, check worker classification guidance against IRS and Department of Labor materials, and verify state treatment with your own state’s tax agency before filing.
Mileage Deduction FAQ
Can I deduct the drive from home to a client if I work remotely for one company?
Only if your home office qualifies as your principal place of business for that trade or business, and only if you are self-employed. If you are a W-2 employee, unreimbursed employee travel expenses are not deductible as a miscellaneous itemized deduction, so the question is moot for most employees. For a self-employed contractor with a qualifying home office, the drive to the client is deductible business mileage regardless of distance and regardless of whether the client engagement is temporary or ongoing.
Which method gives a bigger deduction, standard mileage or actual expenses?
Neither wins universally. High business mileage in an inexpensive, efficient, paid-off vehicle usually favors the standard mileage rate. Low mileage in an expensive vehicle with high insurance, heavy depreciation, or a costly repair year usually favors actual expenses. Because business-use percentage is required for both methods, you can calculate both from the same mileage log and take the larger figure, subject to the first-year election and leasing restrictions.
What happens if I never kept a mileage log?
Vehicle expenses are subject to strict substantiation, and a deduction claimed without adequate records can be disallowed entirely on examination. If your records are incomplete, reconstruct what you can from calendars, client invoices, appointment histories, map data, and credit card statements, document how you built the reconstruction, and start keeping a contemporaneous log immediately. A partially supported deduction backed by corroborating evidence is a stronger position than an unsupported round number.
