Understanding business travel expenses and deductions

Business travel can be a significant expense for large and small businesses alike. Luckily, you can claim the bulk of these travel expenses on your taxes.

According to the Global Business Travel Association, business travel spending rose 11% in 2024 and is forecast to top $2 billion by 2028. That makes understanding which expenses qualify as deductions—and how to document them properly—more important than ever.

What are business travel expenses?

Business travel expenses are ordinary and necessary expenses incurred while traveling away from your normal work location (i.e., your tax home) for business purposes.

As a business owner, it's important to understand what qualifies as business travel expenses, as they may be eligible for business tax deductions. Some of the criteria the IRS considers for a business trip are:

• Travel is primarily for business purposes
• You're away from your usual place of business outside of regular working hours
• You need to spend the night to meet your job duties while away

Common examples include:

• Airfare and transportation: Flights, trains, buses, rental cars, rideshares, taxis, tolls, and parking
• Lodging: Hotel rooms and accommodations during business trips
• Meals: Food expenses while traveling (partially deductible—more on that below)
• Incidentals: Laundry, dry cleaning, baggage fees, tips, and business calls

For your team, these expenses could be paid with corporate credit cards, post-trip reimbursements, per diem rates, or cash advances for the business trip.

When are business travel expenses tax-deductible?

Not every trip qualifies for a tax deduction. The IRS has specific rules you need to meet before you can write off travel costs.

The away-from-home rule

You must travel away from your tax home, your regular place of business, for more than a standard workday, and the trip must typically require sleep or rest. A day trip to a nearby city for a meeting usually won't qualify, but an overnight stay for a two-day conference will.

Temporary work assignments also count, as long as the assignment lasts less than one year, you can deduct travel expenses for the duration.

The primary purpose test

If your trip combines business and personal travel, you can only deduct transportation costs if the trip is primarily for business. The IRS generally looks at how many days you spent on business activities versus personal ones.

For example, if you fly to a city for a four-day conference and tack on two days of sightseeing, the trip is still primarily business. You can deduct the full cost of your flight, but you can only deduct lodging and meals for the four business days.

Rules for international business travel

Stricter allocation rules apply when you travel abroad. If your international trip mixes business and personal days, you generally need to allocate expenses proportionally between the two.

Say you spend five days in London on business and three days exploring the city. You'd deduct five-eighths of your lodging and meal costs, not the full amount. The IRS pays closer attention to international trips, so keep detailed records of your daily activities.

Rules for family travel expenses

Bringing your spouse or family along? Their travel expenses generally aren't deductible unless they're bona fide employees of your business and have a legitimate business reason for attending the trip.

If your partner joins you at a conference but doesn't participate in any business activities, you can still deduct what the trip would have cost for you alone—just not the incremental cost of their travel, meals, or lodging.

What is a tax home?

Your tax home is your regular place of business or post of duty, not necessarily where you live. If you work in one city but live in another, your tax home is where you work. If you do not have a regular place of business, it may default to your home address.

Deductible business travel expenses

Here's a detailed breakdown of what qualifies as a deductible travel expense and how the IRS treats each category.

Transportation costs

Transportation between your tax home and your business destination is fully deductible. This includes airfare, train tickets, bus fare, rental cars, taxis, rideshares, tolls, and parking fees. If you use your personal vehicle, you can deduct the actual expenses or the standard mileage rate, plus gas, tolls, and parking.

Shipping costs for baggage, samples, or display materials between work locations also count.

Lodging and accommodations

Hotel and lodging costs are fully deductible when you're traveling for business. The key requirement is that your accommodations must be reasonable—the IRS won't allow deductions for lavish or extravagant stays that go beyond what's necessary.

Meals during business travel

Meals are generally deductible at a reduced rate while you're traveling for business. They must be ordinary, necessary, and not lavish or extravagant.

As an alternative to tracking every receipt, you can use the IRS per diem rates for meals and incidentals. Per diem simplifies recordkeeping since you don't need to save individual meal receipts—just document the business purpose of the trip.

Incidental and miscellaneous expenses

Incidental expenses add up quickly on business trips. Deductible incidentals include laundry and dry cleaning, baggage fees, tips for service staff like hotel housekeeping and porters, and other minor travel-related costs.

Business communication costs

Any costs you incur to stay connected while traveling are deductible. This includes business calls, internet access fees, and even fax charges if your business still uses them.

What's not a valid business travel expense?

You can't claim an expense that's personal in nature or that benefits you personally more than your business. Examples include:

• Personal vacation days or leisure activities while traveling for business
• Traveling with a spouse or companion (unless they're an employee with a business purpose)
• Personal expenses like gifts or souvenirs purchased during the trip
• The cost of commuting to your normal place of work

What travel expenses are tax-deductible for self-employed individuals?

If you're a sole proprietor, freelancer, or independent contractor, you claim travel deductions on Schedule C of your tax return. The same general IRS rules apply, but a few areas deserve special attention.

Vehicle and mileage deductions

You have two options for deducting vehicle expenses: the actual expense method or the standard mileage rate. The actual expense method lets you deduct gas, maintenance, insurance, depreciation, and other costs based on the percentage of business use. The standard mileage rate gives you a flat per-mile deduction set by the IRS each year.

You can choose whichever method results in a larger deduction, but you need to pick the standard mileage rate in the first year you use the vehicle for business if you want to use it at all.

Home office to client travel

If you work from a home office, travel to client sites or temporary work locations is deductible. This is different from commuting—driving from your home to a regular office isn't deductible, but driving from your home office to a client meeting is.

This distinction can add up to meaningful savings if you regularly visit clients, job sites, or temporary work locations.

Can employees deduct work-related travel expenses?

After the Tax Cuts and Jobs Act of 2017, most W-2 employees can no longer deduct unreimbursed travel expenses on their personal tax returns. This change eliminated the miscellaneous itemized deduction that employees previously used to write off work-related travel costs.

There are a few exceptions. Armed Forces reservists, qualified performing artists, and fee-basis state or local government officials can still deduct unreimbursed employee expenses using Form 2106.

For everyone else, the best path is to seek reimbursement through your employer's accountable plan. Reimbursements under an accountable plan aren't taxable income to you, so you get the same financial benefit without needing to itemize deductions.

IRS travel reimbursement guidelines

Employers can reimburse employees for business travel costs tax-free—as long as they follow IRS rules. The two main frameworks are accountable reimbursement plans and per diem rates.

Accountable reimbursement plans

An accountable plan must meet three requirements: the expense must have a business connection, the employee must provide adequate accounting within a reasonable time, and the employee must return any excess reimbursement.

When you follow these rules, reimbursements aren't taxable income to the employee and aren't subject to payroll taxes. If your plan doesn't meet all three requirements, the IRS treats reimbursements as taxable wages.

Per diem rates for business travel

Per diem is a daily allowance that covers lodging, meals, and incidentals. The IRS publishes rates annually based on location—high-cost cities like New York and San Francisco have higher rates than smaller markets.

Using per diem simplifies recordkeeping for both employers and employees. Instead of collecting and reviewing individual receipts for every meal and incidental, you pay a flat daily rate and document the business purpose of the trip.

How to deduct travel expenses on your taxes

Where you claim your travel deductions depends on your business structure.

• Self-employed (sole proprietors): Report travel expenses on Schedule C (Form 1040) as business expenses that reduce your net self-employment income
• Partnerships and S-corps: Deduct travel expenses through your business tax return, which flows through to individual partners or shareholders
• Employees with exceptions: Use Form 2106 to claim unreimbursed employee business expenses if you qualify under one of the limited exceptions

If your situation is complex—say you're a partner in one business and a sole proprietor in another—consult a tax professional to make sure you're claiming deductions correctly.

How to document business travel expenses

Proper documentation is the difference between a clean deduction and a failed audit. The IRS requires specific records to support every travel expense you claim.

Required records for tax deductions

For each expense, the IRS wants to see:

• Amount: The exact cost of each expense
• Date: When the expense occurred
• Place: The location or destination
• Business purpose: Why was the travel necessary
• Business relationship: Names of people entertained, if applicable

Keep receipts for lodging and any expense over $75. For smaller expenses, a log or record with the details above is generally sufficient. Expense management software can automate much of this recordkeeping.

How long to keep travel expense records

The IRS generally requires you to keep records for at least three years from the date you file your return. If you underreport income by more than 25%, that window extends to six years.

Play it safe and keep your travel expense records for at least six years. Digital storage makes this easy—scan your receipts and store them alongside your expense reports so everything is in one place if you ever need it.

Manage business travel costs with Ramp

Business travel expenses can spiral out of control faster than you realize. Between last-minute flight changes, client dinners that exceed budgets, and employees booking premium hotels without approval, travel spending often becomes a black hole in your budget. By the time you catch overspending in monthly reports, the damage is already done.

Ramp tackles this problem head-on with real-time spending controls that work automatically. When you use Ramp Travel to book flights and accommodations, you can set precise spending limits by category—$200 per night for hotels, $300 for flights, or whatever fits your policy. These aren't just guidelines; they're hard stops. If an employee tries to book a $300 hotel room when their limit is $200, the transaction simply won't go through. No awkward reimbursement denials, no policy violations to address after the fact.

The platform's automated receipt matching takes the administrative burden off your team while ensuring compliance. As soon as an employee swipes their Ramp card for that client dinner, they get a text requesting the receipt. The system automatically matches receipts to transactions and flags any missing documentation, eliminating the end-of-month scramble to track down expense reports. This real-time visibility means you spot unusual spending patterns immediately—like when someone's daily meal expenses suddenly triple—rather than discovering them weeks later.

Ramp's merchant-specific controls add another layer of precision. You can block entire categories of merchants or set different limits for different vendors. Need to ensure employees book with preferred hotel chains? Set higher limits for those specific merchants while restricting others. These granular controls transform travel expense management from reactive damage control into proactive spending optimization, giving you peace of mind that your travel budget stays exactly where you planned it.
