Is every work trip a tax write-off?

Where the claim comes from

Business owners often treat any trip connected to work as travel and deduct everything along the way: mileage, meals, and even the daily drive to the office. Part of the confusion is that the tax law uses two different ideas that sound alike: travel away from home, and local transportation.

Each has its own rules. Mixing them up leads to deductions that do not hold up, and sometimes to missed deductions that would have been allowed.

What the law actually says

IRC §162(a)(2) allows a deduction for traveling expenses, including meals and lodging that are not lavish or extravagant, while away from home in the pursuit of a trade or business. In United States v. Correll, 389 U.S. 299 (1967), the Supreme Court upheld the IRS rule that a trip counts as away from home for meal deductions only if it requires sleep or rest. IRS Publication 463 describes this as being away from the general area of your tax home substantially longer than an ordinary day's work, and needing sleep or rest to meet the demands of your work.

Your tax home is generally your regular place of business or post of duty, regardless of where you maintain your family home. If you have no regular place of business, your tax home may be where you regularly live, and if you have neither, you may be treated as an itinerant with no tax home to be away from.

Local transportation is different. Under Rev. Rul. 99-7, daily transportation between your residence and a temporary work location outside the metropolitan area where you live and normally work is deductible. If you have a regular work location away from your residence, or your home is your principal place of business under IRC §280A(c)(1)(A), trips to other work locations in the same business can also be deductible. Commuting between your residence and a regular work location remains personal, no matter how far it is.

IRC §274(d) requires adequate records or sufficient evidence corroborating your own statement for travel expenses, and IRC §274(n) generally limits business meal deductions to 50%. For employees, IRC §67(h), as amended by the One Big Beautiful Bill Act, permanently disallows miscellaneous itemized deductions, so unreimbursed employee travel is generally not deductible on the federal return.

What is true and what is not

It is true that genuine business travel away from your tax home can be deductible, including transportation, lodging, and 50% of meals, when the trip's primary purpose is business and you keep the required records.

It is not true that every work-related trip qualifies as travel. A day trip does not support meal deductions as travel. Your drive from home to your regular office is commuting. On the other hand, it is also not true that nothing short of an overnight trip is deductible: driving between client sites during the day or to a qualifying temporary work location can be deductible local transportation.

• Overnight trip away from your tax home for business: transportation, lodging, and 50% of meals may be deductible.
• Day trip to a client or temporary work location that qualifies under Rev. Rul. 99-7: transportation may be deductible; meals generally are not travel meals.
• Home to regular office: commuting, not deductible.
• Trip with personal days mixed in: allocation rules apply.

What to do instead

Sort your trips into three groups: travel away from home, local business transportation, and commuting. Record the date, destination, business purpose, and miles or costs for each business trip when it happens. For 2026, the IRS business standard mileage rate is 72.5 cents per mile if you use the standard mileage method.

If you are an employee, ask your employer about reimbursement under an accountable plan. If you own the business, consider adopting an accountable plan so that reimbursed travel is handled consistently and documented.
