What counts as business travel for taxes?
Business travel, for tax purposes, means your work takes you away from the general area of your tax home for longer than an ordinary day, and you need to sleep or rest to do the work. IRS Publication 463 sets out both conditions. It adds that the rest requirement "isn't satisfied by merely napping in your car."
Your tax home is generally your regular place of business, wherever your family home happens to be. For most freelancers and small business owners that's the city where they normally work.
Two more points from Publication 463 often matter:
- Temporary vs. indefinite work. If you realistically expect a job away from home to last a year or less, and it does, it's generally temporary, and travel there can count. If you expect it to last longer, that place generally becomes your tax home and the travel costs stop counting.
- The trip has to be for business. A trip that's mainly a vacation doesn't become a business trip because you took one meeting. Trips that mix business and personal days have their own rules, covered in mixed business and personal trips.
What business travel expenses are deductible?
Publication 463 lets you deduct the ordinary and necessary costs of traveling away from home on business. Its Table 1-1 summarizes the usual categories:
| Category | What's generally included | Watch out for |
|---|---|---|
| Transportation | Airfare, train, bus, or car between your home and the business destination | A free frequent-flyer ticket has a cost of zero |
| Local transportation | Taxi, shuttle and similar fares between the airport or station, your hotel, and client or work locations | Keep fares for personal outings separate |
| Car | Actual car expenses or the standard mileage rate, plus business tolls and parking; a rental car's business-use share | Personal side trips in the car aren't business use |
| Lodging | What you actually paid for the room on business nights | No per diem shortcut for the self-employed |
| Meals | Food, beverages, tax and tips while away overnight | Generally 50% deductible; nothing lavish or extravagant |
| Incidentals | Tips to porters, baggage carriers and hotel staff | Laundry, lodging taxes and phone calls are separate categories, not "incidentals" |
| Cleaning and calls | Dry cleaning, laundry, business calls on the trip | |
| Shipping | Sending baggage, samples or display material | |
| Other | Similar ordinary and necessary costs, such as computer rental |
If a hotel bundles meals into the room rate, Publication 463 says you need a reasonable basis for splitting the charge between meals and lodging.
Is business travel 100% deductible?
Generally not. Most travel costs can be deducted in full, but meals are generally limited to 50%, and Publication 463 says the 50% limit applies "even if the unreimbursed meal expense is for business travel." The temporary 100% deduction for restaurant meals covered only 2021 and 2022, so it doesn't apply for tax year 2026. Days spent on vacation, and costs for people who aren't there for business, are generally not deductible at all. For more on meals, see the business meals deduction guide.
Can self-employed people use per diem instead of meal receipts?
Yes, for meals and incidentals, but not for lodging. Publication 463 says you "can use the standard meal allowance whether you are an employee or self-employed." That allowance is the federal rate for meals and incidental expenses (M&IE) where you stayed. It also says there is "no optional standard lodging amount," so your hotel deduction is your actual cost.
Rules that come with the per diem:
- You still need records of the time, place and business purpose of the trip.
- The 50% limit applies to the allowance.
- On the day you leave and the day you return, you prorate. One method Publication 463 allows is claiming 3/4 of the daily rate.
- If you had no meal costs, an incidental-expenses-only option of $5 a day is available instead.
The federal per diem year runs October to September. The standard M&IE rate in the continental US is $68 a day under both the FY2026 and FY2027 GSA bulletins. Many cities have higher rates, in tiers up to $92. Look up the rate for each place you stayed at gsa.gov.
Example: a four-day client workshop
A freelance UX designer with a tax home in Denver flies out for a client workshop from Tuesday to Friday. All numbers are fictional, and the destination's M&IE rate is assumed to be $68.
| Cost | Amount | Generally deductible |
|---|---|---|
| Round-trip airfare | $420 | $420 |
| Hotel, 3 nights at $189 | $567 | $567 |
| Rideshares, airport and client office | $64 | $64 |
| Laundry | $18 | $18 |
| Meals, actual receipts | $236 | $118 (50%) |
| Total | $1,305 | $1,187 |
With the per diem instead, the meals would be 2 full days at $68 ($136) plus 2 travel days at 3/4 of $68 ($102), for $238. At 50%, that's $119, close to the actual-cost figure. Either way, the designer and their CPA decide which method fits and whether each cost qualifies.
What records do I need for a business trip?
Publication 463's Table 5-1 lists the elements to prove for travel:
| Element | What to record |
|---|---|
| Amount | Each separate cost for travel, lodging and meals; incidentals can be totaled in reasonable categories such as taxis or tips |
| Time | The dates you left and returned, and the number of days spent on business |
| Place | The destination (city or area) |
| Business purpose | Why you went, or the business benefit you gained or expected |
You generally need documentary evidence such as a receipt for lodging, whatever the amount, and for other costs of $75 or more. A record made at or near the time, such as a weekly log, counts as timely. The details are in IRS receipt requirements.
What's different for tax year 2026?
For tax year 2026 (returns filed in 2027):
- Mileage changed mid-year. If you drove, the business rate is 72.5 cents a mile for January 1 to June 30, 2026, and 76 cents from July 1, 2026 (Announcement 2026-11). The 2025 rate was 70 cents for the whole year. Split your trip miles at July 1. See the 2026 mileage guide.
- Meals are still 50%. A new 2026 rule takes away the deduction for some meals employers provide on-site. It doesn't change the 50% treatment of travel meals.
- Per diem rates rolled over on October 1, 2026. The standard M&IE stayed at $68. The higher federal lodging rate doesn't help self-employed travelers, who deduct their actual lodging cost.
Where Amy fits
A trip is a dozen charges that only make sense together. Amy finds them in the records you already have, asks you what the trip was for, and shows you and your CPA the whole of it. You decide what counts.
