How we wrote this: A plain-English summary of IRS Tax Topic 511 (Business travel expenses) and Publication 463, Travel, Gift, and Car Expenses (the 2025 edition), checked October 29, 2026. This is general information, not tax advice. Meals have their own limits; see our guide to the business meals deduction.
A client visit two states away, a trade show, a week on a temporary job site: if you're self-employed, the travel can be deductible, but only if it meets the IRS definition of being away from home. Here are the rules in IRS Topic 511 and Publication 463.
The basic rule
The IRS defines travel expenses as the ordinary and necessary expenses of traveling away from home for your business or profession. You can't deduct expenses that are for personal purposes, or business meals that are lavish or extravagant.
Most employees can't deduct unreimbursed travel. The IRS lists exceptions for National Guard and military reserve members, qualified performing artists, fee-based state or local government officials, employees with impairment-related work expenses, and eligible educators. This guide focuses on the self-employed, who deduct travel on Schedule C (farmers use Schedule F).
Are you "away from home"?
Per the IRS, you're traveling away from home if:
- your duties require you to be away from the general area of your tax home for substantially longer than an ordinary day's work, and
- you need to sleep or rest to meet the demands of your work while away.
A day trip, however long the drive, usually isn't "away from home" travel; the car costs fall under the mileage rules instead (see our 2026 mileage rate guide).
Your tax home isn't always where you live
The IRS says your tax home is generally the entire city or general area where your main place of business or work is located, regardless of where your family lives. Its example: you live in Chicago but work in Milwaukee during the week, staying in a hotel, and go home on weekends. Milwaukee is your tax home, so the Milwaukee hotel and meals aren't deductible, and neither is the weekend travel home.
If you regularly work in several places, your tax home is the area of your main place of business. The IRS weighs the time you spend at each place, the business activity there and the income from each, and says time spent is the most important factor.
Temporary vs. indefinite work assignments
You can deduct travel for a temporary work assignment away from home, but not an indefinite one. Per the IRS:
- An assignment of more than one year is indefinite.
- If you realistically expect to work somewhere more than a year, travel there isn't deductible, even if it ends sooner.
- If you expected a year or less and that expectation changes, travel becomes nondeductible from the point the expectation changes.
What you can deduct
IRS Topic 511 lists deductible travel expenses, including:
| Expense | Notes from the IRS |
|---|---|
| Getting there: plane, train, bus or car between your tax home and the business destination | If the ticket was free (for example, through a frequent traveler program), your cost is zero |
| Local transportation: taxis and similar fares | Between the airport or station and your hotel, and between the hotel and client sites, meetings or your temporary work location |
| Your car at the destination | Actual expenses or the standard mileage rate, plus business tolls and parking; for a rental car, only the business-use portion |
| Lodging and non-entertainment meals | Meals are generally limited to 50% of the unreimbursed cost; you can often use a standard meal allowance instead of tracking actual costs |
| Shipping baggage and sample or display material | Between your regular and temporary work locations |
| Dry cleaning and laundry | |
| Business calls and communications during the trip | |
| Tips for any of the services above | |
| Other ordinary and necessary travel costs | For example, transportation to a business meal or computer rental fees |
Conventions are deductible if you can show attendance benefits your business; special rules apply to conventions outside North America.
Trips that mix business and pleasure
For travel within the United States (the 50 states and D.C.), Publication 463 says:
- Entirely business: deduct all of your travel expenses.
- Primarily business, with some personal time (extra vacation days, a side trip): deduct only the business-related expenses, which include the cost of getting to and from the business destination.
- Primarily personal (a vacation): the whole trip is nondeductible, though you can deduct expenses at the destination that are directly related to your business.
Publication 463's example: a 6-day business trip from Atlanta to New Orleans cost $1,633.50; with a 3-day stop to visit family on the way home, the total was $2,165. The deductible amount is $1,633.50, what the trip would have cost without the personal stop (with meals still subject to the 50% limit).
If part of the trip is outside the United States, separate rules apply to that part; see Publication 463.
Bringing someone along
Generally you can't deduct travel costs for a spouse, dependent or other person who comes with you. Publication 463 allows it only if that person is your employee, has a bona fide business purpose for the trip, and would otherwise be allowed to deduct the travel. Incidental help, such as typing notes, isn't enough. The same test (minus the employee requirement) applies to a business associate, such as a customer, client or supplier, traveling with you.
Keep records
The IRS says good records are essential; Topic 305 covers recordkeeping, and Publication 463 explains what to keep for travel. See our guide to how long to keep business records.
