Learning how to write off travel expenses can save your business thousands of dollars each year. They also empower owners to network, visit clients, and attend valuable workshops.

What qualifies as a business trip for tax deductions?

The IRS allows tax deductions on certain travel expenses when the trip's main purpose directly relates to your business. Since the line between business and nonbusiness travel is hard to draw, you can take a few steps to ensure your trips' overhead costs qualify.

A list of travel expenses deductible criteria.

For a trip to qualify as business travel tax deductions, you must:

Taking these steps to ensure your travel qualifies for a tax deduction will ensure you get the correct deductions.

Which travel expenses are tax deductible?

Understanding business tax deductions is easier with a list of example write-offs. While most expenses outside your tax home qualify for deductions, here are the most common travel expenses that are tax deductible:

However, there are some travel expenses you can’t deduct, such as family travel and lodging costs, entertainment, and unnecessary or unreasonable expenses.

For example, you may deduct your plane tickets from your home to the destination, a lunch meeting with a client, and a rented computer while traveling. However, you can’t deduct the hotel stay for your family members or if you take your client to a concert.

Two scenarios to understand when you can write off travel expenses.

How to write off travel expenses on your taxes

Even if you go on a trip for business purposes, incorrectly filing your tax deductions could stand in the way of a write-off. To ensure the IRS covers every expense, plan your write-offs before leaving and hold onto your receipts once you get home. The main steps to follow include:

1. Confirm your eligibility

Before you can bank on a write-off, you must ensure a trip is eligible for business deductions. The IRS uses rigid criteria to weigh business expenses, so make sure your write-offs meet all the standards.

The eligibility criteria for a business trip tax deduction include:

Additionally, you can write off lodging, taxis, car rentals, and 50% of your food costs on business days. You can also deduct laundry, dry cleaning, personal grooming, and other “ordinary and reasonable” expenses for the trip.

Likewise, only 50% of your food costs are deductible, along with your portion of the lodging. So, if you usually rent a single hotel room but need a double and another room for the family, you can only deduct the cost of a single room. If you make a layover in another city for personal reasons, you cannot deduct those related travel expenses.

Tip: The IRS counts travel days as business days, along with any weekends or holidays sandwiched between appointments. If you schedule your time right, you can squeeze in personal vacation time and only have to pay for lodging, meals, and other personal expenses on days that don’t qualify as business days.

For example: If you plan to leave on a Thursday and have a business appointment on Friday and Monday, you will have accumulated five business days and can write off all expenses for them.

2. Make sure expenses are ordinary and necessary

Business owners who try to deduct unnecessary or unreasonable expenses from their taxes may run into trouble. While you can deduct the cost of taking a client to dinner, that doesn’t mean you should spring for a thousand-dollar bottle of wine. Avoiding extravagant fees makes the IRS more likely to accept your deduction.

Note : The IRS offers a temporary 100% deduction on business meals ordered from a restaurant between Dec 31, 2020, and Jan 1, 2023. In all other cases, the write-off is 50%.

3. Save all receipts from a trip

Track all expenses by holding onto every receipt from your trip. While not every expense will earn a write-off, it’s worth checking in with a tax professional before throwing any away. Over time, small write-offs and unexpected deductions lead to huge savings.

The IRS doesn’t require that you keep receipts for payments less than $75, but you do need to keep a log of the time and date of the expenses. To streamline the process, you can use QuickBooks expense tracking software .

4. Itemize your expenses

Once you narrow down the receipts eligible for a deduction, organize them into different categories. Group food, transport, and lodging fees into their own folder and write notes explaining when and how you made each expenditure. You'll be in good shape during tax season if you do this while the information is fresh.

Earning a travel deduction means keeping accurate records of your spending. On a business trip, you should tally up your fees on an expense sheet.

Use this free travel expenses write-off calculation sheet to find the estimated amount you can write off for travel expenses. Make a copy of the spreadsheet and input your expenses by category to use the total as a reference.

5. File your write-off correctly

Once tax season rolls around, you need to make sure that you properly file your travel expenses. For self-employed travel expenses, you will list travel write-offs on Schedule C Form 1040. Businesses must claim travel expenses on Form 2106 and report them on Form 1040 or Form 1040-SR as an adjustment to their total income.

While there’s no annual travel deduction limit, the IRS scrutinizes higher write-offs. Be sure to calculate your business expenses with a tax attorney before submitting a large filing.

How to calculate business travel expenses

To calculate the estimated travel deductions, you can use one of the following formulas. When tallying write-offs, be careful about what you consider a business expense. While baggage fees, laundry costs, and admission to a workshop all count, you shouldn’t include personal expenses like souvenirs. Additionally, you can only write off entertainment costs when treating a client, vendor, or business acquaintance.

Business trip with no personal days

This formula applies to business trips that involve no personal days. The entire trip consists of travel and business purposes.

Travel deduction = Transportation + lodging + business expenses + (meals / 2)

Business trip with personal days in the middle

This formula applies to business trips with vacation time sandwiched between business days. As long as you spend more time on business than leisure, you can include transport and lodging costs in your deductions.

Travel deduction = Transportation on business days + lodging + business expenses + (meals on business days / 2)

Other trips involving business

This formula applies to trips that are mostly for business with vacation days at the beginning or end or personal vacations with at least one business day. You cannot deduct any fees from personal days, so you will end up spending much more on lodgings and transport.

Travel deduction = Transportation on business days + lodging on business days + business expenses + (meals on business days / 2)

Example business vacations you could write off

If your business requires you to travel, you could be missing deductions that can shrink your taxable income and grow your bottom line. While travel expenses must be business-related to be 100% deductible, taking a little vacation time during a trip isn’t unusual.

With that in mind, here are some ideas that you might be able to coordinate with or plan “in and around” your holiday travel to maximize your tax deductions.

While these ideas might begin as a tax write-off, they can grow into a relationship with clients, business partners, and vendors.

Things to consider when writing off travel expenses for holiday travel

Some businesses keep working through the holiday season, so you may find some overlap between family and business. However, IRS auditors invest time and resources into ensuring these expenses relate to business and not a holiday trip.

Examples of which holiday fees are deductible during business travel.

Here are the main points to consider when deducting write-offs during holiday travel:

Remember to follow IRS guidelines. Passing vacation expenses off as a business write-off will trigger an IRS audit. The IRS may level a fine and revoke other business write-offs. So, to keep earning future tax deductions, stay within IRS guidelines and pay for your own vacation expenses.

Find peace of mind come tax time

Going on a business trip is a worthwhile opportunity to expand your business, meet potential investors, and boost professional development. Whatever the reason for your next business trip, learning how to write off travel expenses can help you save money to invest in other areas of your business.

Whether you're a solopreneur going on your first business trip or you have regular meetings across your state’s borders, keeping records of your expenses is crucial to claim tax deductions. An accounting software like QuickBooks Self-Employed can help you track your expenses on the go so you never lose a receipt.

How to write off travel expenses FAQ

What are disallowed business expenses?

If someone claims a deduction they don’t qualify for, the IRS penalizes them for these disallowed business expense deductions. This penalty occurs when business owners use write-offs to pay substantially less income tax than they should have.

In general, the IRS defines substantially less as the equivalent of a difference of 10% of what a business owner owes, or $5,000—depending on which is higher. Not only will the IRS audit you for disallowed deductions, but they’ll also charge a fine.

What is the penalty for a disallowed business expense?

Business owners have to pay a penalty for disallowed expenses. They owe 20% of the difference between what they needed to pay and what they actually paid for their income tax. In other words, if you write off disallowed business expenses, you must pay 120% of your tax obligation.

How do I prove travel expenses for taxes?

To prove travel expenses for taxes, you should keep a record of your expenses, such as receipts, vouchers, and invoices. As a general rule of thumb, don’t write off an expense unless you can prove it relates to work. Keep your records handy to discuss the expenses and accurately fill out tax forms with your CPA at the end of the year for a well-balanced tax return.
