Business Travel Expenses Deduction: 2026 Tax Rules

Business travel expenses are deductible when you travel away from your tax home for work and the costs are ordinary and necessary. Airfare, lodging, rental cars, and tips are generally fully deductible, while meals on the road are limited to 50%. This guide covers what qualifies in 2026, the records the IRS expects, and how a self-employed filer claims it.

Are business travel expenses tax deductible?

Yes. Business travel expenses are deductible as ordinary and necessary business expenses under Internal Revenue Code section 162. To qualify, the trip has to take you away from the general area of your tax home for a period substantially longer than an ordinary day's work, and it has to require you to get sleep or rest. That away-from-home-and-overnight test comes from IRS Topic No. 511 and Publication 463.

Your tax home is the entire city or general area where your main place of business sits, not where your family lives. So a trip from your home office to a client three states away is travel. Driving across town to a regular worksite is commuting, which is never deductible. The Supreme Court drew that tax-home line in Commissioner v. Flowers back in 1946, and Publication 463 still applies it today.

Are business travel expenses 100% deductible?

No, not all of them. Transportation and lodging are generally 100% deductible, but business meals while you travel are capped at 50% under section 274(n). So a $400 flight and a $200 hotel night come off in full, while a $60 dinner on the trip gives you a $30 deduction. Anyone telling you a whole business trip is fully deductible is glossing over the meal limit.

The 50% meal cap applies whether you track actual restaurant costs or use the federal per diem meal allowance. The short-lived 100% write-off for restaurant meals applied only to 2021 and 2022 and has expired, so travel meals are back to 50% for 2026.

What counts as a business travel expense?

A business travel expense is any ordinary and necessary cost of traveling away from your tax home for work. Publication 463 lists the deductible categories, and they cover almost everything a normal work trip runs up. The expense has to be reasonable for the situation, not lavish, and tied to your trade or business.

The deductible list includes:

• Airfare, train, or bus fare between your home and the business destination
• Fares for taxis, rideshares, and airport shuttles, including the ride between the airport and your hotel and between your hotel and a work location or client
• Shipping baggage or sample and display material between your regular and temporary work locations
• Car costs at the destination, figured with actual expenses or the standard mileage rate
• Lodging for any overnight stay that requires sleep or rest
• 50% of non-entertainment meals
• Dry cleaning and laundry while away
• Business phone calls and other communication
• Tips you pay on any of these services

Other ordinary and necessary travel costs, like a hotel internet charge for work, fit under the same rule. Personal costs on the trip, like a spa visit or a sightseeing tour, do not.

Can I deduct mileage for business travel?

Yes. If you drive your own car for business travel, you can deduct the miles using the IRS standard mileage rate or your actual car expenses. The standard mileage rate for 2026 is 72.5 cents per mile, up from 70 cents in 2025, per IRS Notice 2026-10. Multiply your business miles by the rate, and that figure replaces gas, oil, depreciation, and maintenance for those miles.

You still need a mileage log showing the date, destination, business purpose, and miles for each trip. The standard mileage method does not waive that recordkeeping. If you instead claim actual expenses, you deduct the business-use percentage of gas, repairs, insurance, and depreciation, and you keep the receipts to back it up.

How does per diem work for travel?

Per diem lets you deduct a flat daily allowance for lodging and meals instead of tracking every receipt. The federal standard rate for the continental US in fiscal year 2026 is $178 a day, made up of $110 for lodging and $68 for meals and incidental expenses (M and IE), effective October 1, 2025 through September 30, 2026. Hundreds of higher-cost cities have their own larger rates set by the GSA.

Two cautions. The meals portion of any per diem is still subject to the 50% limit when you take the deduction. And self-employed taxpayers can use the per diem rate for meals but generally must use actual cost for lodging, so per diem is not a free pass on hotel receipts for a sole proprietor.

Do I need receipts for travel expenses?

You need a receipt for any travel expense of $75 or more, and you always need one for lodging no matter the amount. That $75 threshold sits in Treasury Regulation 1.274-5(c)(2)(iii), set by Notice 95-50 in 1995, and it still applies in 2026. Below $75 the receipt is optional, but the written record never is.

Under section 274(d), every travel deduction needs four recorded elements: the amount, the time (your dates of departure and return and the days spent on business), the place, and the business purpose. The $75 rule only excuses you from keeping the paper slip on smaller items. It does not excuse you from logging those four facts. Because the threshold is so low and lodging always needs proof, the safe habit is to keep a receipt for everything on the trip.

Can I deduct a trip that is part business and part personal?

It depends on the main purpose of the trip. For travel inside the US, if the trip is primarily for business, your round-trip transportation is fully deductible even if you tack on a few personal days, and you deduct your business-day costs at the destination. If the trip is primarily personal, the cost of getting there is a nondeductible personal expense, though you can still deduct the specific business expenses you incur once there.

Personal-day costs are never deductible either way. If you fly to a conference for three business days and stay two extra days to sightsee, the airfare still deducts because the trip was mainly business, but the two personal hotel nights and those meals do not. Keep a simple day-by-day note of which days were business so the split is defensible.

Can I deduct my spouse's travel costs?

Usually no. You cannot deduct the travel costs of a spouse, family member, or other companion who comes along unless three things are true: the person is your bona fide employee, they have a real business reason to make the trip, and they would otherwise be able to deduct the cost themselves. That rule is in section 274(m)(3) and Publication 463.

A spouse who helps with light tasks like taking notes or entertaining clients does not meet the test. If your spouse rides along for company, you can still deduct what the trip would have cost you alone, such as a single hotel room rate, just not the added cost of bringing them.

Are conferences and conventions deductible?

Yes, if attending benefits your trade or business. Travel to a convention, seminar, or trade show inside the North American area is deductible like any other business trip, as long as the agenda connects to your work and the cost is reasonable. The North American area includes the US, Canada, Mexico, and certain US territories.

Conventions held outside that area must pass an added reasonableness test before they deduct. Conventions held on cruise ships face the tightest limit: the deduction is capped at $2,000 per person per year and only for US-registered ships sailing US ports, with signed statements attached to your return. Do not confuse that yearly cruise-convention cap with the separate daily limit on luxury water travel.

How do I write off travel on Schedule C?

Sole proprietors and single-member LLCs report travel on Schedule C. Put transportation, lodging, and other travel costs on Line 24a (Travel), and put your deductible meals, already reduced to 50%, on Line 24b. Keeping meals on their own line lets the IRS see you applied the limit.

The cleanest way to fill those lines is to capture each receipt as the trip happens, pull out the vendor, date, total, and tax, and total them at filing time. A receipt to Excel converter turns a folder of airfare, hotel, and taxi slips into a spreadsheet you can sum by category, with the meal total already separated so you can halve it. If your hotel or airline sends an itemized bill rather than a receipt, you can extract the data from that travel invoice the same way.

Business travel deduction FAQ

Is commuting a business travel expense?

No. The cost of getting between your home and your regular place of work is commuting, and it is never deductible, no matter how far the drive. Travel only counts when it takes you away from your tax home overnight for business. A trip from your office to a client across the state is deductible; the daily drive to that office is not.

Can I deduct travel for a temporary work assignment?

Yes, if the assignment is temporary. Travel and living costs for a work assignment away from your tax home are deductible when the job is realistically expected to last one year or less and in fact does. If the assignment is expected to run longer than a year, it is treated as indefinite, your tax home shifts there, and the travel stops being deductible.

Are travel meals deductible if I eat alone?

Yes. Unlike a client meal, a meal you eat by yourself while traveling away from home for business is still 50% deductible. You do not need a business companion at the table. Keep the receipt for anything $75 or more and note the trip it belonged to, the same as any other travel meal.

Keep your travel records audit-ready

Travel is one of the most examined deductions because the trips mix business and personal so easily. The fix is boring and effective: capture every receipt on the trip, note the business purpose and dates, and total it when you file. ReceiptOCR reads the vendor, date, amount, and tax off each airfare, hotel, and taxi receipt so your travel log is built from data instead of a shoebox. See how it works for scanning receipts for taxes, building an expense report from receipts, or running a year-round receipt tracker for your small business. Self-employed travelers can start with the receipt scanner for the self-employed. If you submit trip costs to an employer or client instead of deducting them, our guide on how to do an expense report covers the format approvers expect, and smaller teams that find a corporate travel suite heavier than their trip volume can compare a Concur alternative.

If a trip was booked on a corporate card, you can also convert the card statement to Excel to reconcile the charges against your receipts.
