Section 162(a)(2): How the Tax Home Rule and One-Year Test Decide Whether Your Travel Is Deductible

A consultant flies from Atlanta to a client site in Houston every Monday morning and back every Thursday night. A traveling nurse takes a 39-week assignment in San Diego. A construction superintendent moves from one out-of-state project to the next, sometimes for fourteen months at a stretch. A salesperson covers four states but sleeps in her own bed every night.

Which of them can deduct lodging and meals? Which one can't? The answer turns on three concepts buried in a single sentence of the tax code: Section 162(a)(2), the tax home rule, the temporary vs. indefinite distinction, and the one-year rule. Get them right and your travel expenses fall on the deductible side of the line. Get them wrong and you owe tax — sometimes years later, with interest and penalties — on what you thought was reimbursement.

This guide unpacks how the IRS and the courts actually apply Section 162(a)(2) in 2026, with specific dollar thresholds, the per diem rates that simplify recordkeeping, and the traps that catch contractors, consultants, and mobile professionals every year.

What Section 162(a)(2) Actually Says

Section 162(a) of the Internal Revenue Code allows a deduction for "ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business." Subsection (a)(2) goes further, naming a specific category: "traveling expenses (including amounts expended for meals and lodging other than amounts which are lavish or extravagant under the circumstances) while away from home in the pursuit of a trade or business."

Three elements have to line up for a travel cost to qualify:

1. The expense is ordinary and necessary for your business.
2. You are away from home in the tax sense.
3. The travel is in the pursuit of a trade or business, not a personal trip with business activities sprinkled in.

Element two — "away from home" — is where most disputes start, because "home" in Section 162(a)(2) does not mean the place where you keep your toothbrush. It means your tax home, a concept the IRS and the courts have built up over decades.

Defining Your Tax Home

Your tax home is the entire city or general area where your main place of business or work is located, regardless of where your family lives. If you work in Chicago but your spouse and kids live in Madison, your tax home is Chicago. Traveling from Chicago to Madison every weekend is personal commuting, not business travel, and the cost is non-deductible.

If you work in several locations, the IRS looks at three factors to identify your main place of business:

• The total time you spend at each location during the year.
• The degree of business activity at each location.
• The financial return from each location.

Time spent is the strongest factor in most cases. A consultant who spends eight months at one client and four months scattered across others has a tax home where the eight-month client sits, even if she calls another city "home."

The Itinerant Trap

There is a third category nobody wants to land in: the itinerant taxpayer. If you have no regular place of business and no regular place where you live, the tax code says you have no tax home at all. You are never "away from home" — because you have no home to be away from — and you cannot deduct travel expenses anywhere.

In Deamer v. Commissioner (8th Cir. 1985), a contract aircraft engineer worked successive temporary assignments in different cities, with no permanent residence in between. The court called him itinerant and disallowed his travel deductions. In Henderson v. Commissioner, a stagehand for a traveling ice show kept a room at his parents' house in Boise but spent most of the year on the road. The Tax Court found he had no business reason to return to Boise and treated him as itinerant.

The IRS applies a three-factor test to decide whether a claimed home is real enough to anchor a tax home:

1. Do you perform business in the vicinity of the claimed home (some local clients, an office, occasional jobs)?
2. Do your living expenses get duplicated because business travel forces you to maintain two homes?
3. Have you not abandoned the vicinity — meaning family lives there, you use it for lodging frequently, and you have a real economic connection?

Pass all three and the IRS will accept your claimed abode as a tax home. Fail one or two and you risk losing your travel deductions for the entire year.

The Sleep or Rest Rule

Even when you have a clear tax home, not every business trip qualifies as "away from home." In United States v. Correll, 389 U.S. 299 (1967), the Supreme Court endorsed the IRS's bright-line sleep or rest rule: meals and lodging are deductible only if your trip is long enough that you reasonably need sleep or rest to perform your duties.

Mr. Correll was a traveling grocery salesman who left his Tennessee home before dawn, ate breakfast and lunch on the road, and returned in time for dinner. The Court held that none of his meals were deductible because his trip required neither sleep nor rest — those were personal living expenses, not travel expenses. A salesperson who covers a multi-state territory but is back in her own bed every night fails the sleep-or-rest rule and gets no Section 162(a)(2) deduction for meals.

The practical rule: if the work requires you to stop for a night, you are away from home; if you can complete the round trip in one day without sleeping somewhere else, you are not.

Temporary vs. Indefinite: The Heart of the Test

Once you have a tax home and you are sleeping somewhere else for business, the next question is whether your absence is temporary or indefinite. The distinction controls deductibility entirely.

• A temporary assignment is one expected to last one year or less. While you are on a temporary assignment, you remain "away from your tax home" and may deduct lodging, meals (subject to the 50% cap discussed below), and incidental costs.
• An indefinite assignment is one realistically expected to last more than one year. When an assignment is indefinite, your tax home shifts to the new location. You are no longer "away" — you have arrived. Lodging and meals there become personal living expenses and are not deductible.

The key word is expected. The IRS looks at your realistic expectation at the start of the assignment, and at any point during it where that expectation changes.

How the One-Year Rule Works in Practice

Section 162(a)(2) closes with this language: "the taxpayer shall not be treated as being temporarily away from home during any period of employment if such period exceeds 1 year." The IRS applies it through three scenarios:

Scenario A — Expected to last one year or less, and it does. The trip is temporary throughout. All qualifying travel expenses are deductible for the entire period.

Scenario B — Expected to last one year or less, but later extended beyond a year. The assignment is temporary up to the point the expectation changes. Once you realistically expect to be there more than a year, the assignment becomes indefinite from that moment forward, and travel deductions stop. Travel expenses incurred before the expectation shifted remain deductible.

Example. You take a nine-month contract in Denver while keeping your tax home in Boston. After six months the client extends the contract by another eight months. At the moment of that extension, your total expected stay crosses the one-year threshold and Denver becomes your new tax home. The first six months of lodging and meals are still deductible; nothing after the extension is.

Scenario C — Expected to last more than one year from day one. The assignment is indefinite immediately. Your tax home moves on day one. No travel deductions at all.

A Special Carve-Out for Federal Investigators

Section 162(a) contains a narrow exception: the one-year rule does not apply to federal employees certified by the Attorney General as traveling on temporary duty in connection with investigating or prosecuting a federal crime. That carve-out keeps long-running federal corruption and organized-crime investigations from quietly losing their travel deductions at the twelve-month mark.

What Counts as a Deductible Travel Expense

Once you clear the tax-home, sleep-or-rest, and temporary-assignment tests, a wide range of costs qualifies as ordinary and necessary travel:

• Transportation between your tax home and the business destination — airfare, train, bus, or personal vehicle.
• Local transportation at the destination — airport-to-hotel rides, taxis between meetings, rental cars.
• Lodging at the destination.
• Meals, subject to the 50% deduction cap under Section 274(n).
• Baggage and shipping for samples, materials, or work product.
• Vehicle expenses — actual costs or the standard business mileage rate (72.5 cents per mile for 2026).
• Dry cleaning and laundry while away.
• Business communications — phone, fax, internet on the road.
• Tips related to any of the above.

"Lavish or extravagant" expenses are disallowed, but the IRS interprets this narrowly: a hotel that is appropriate to your business circumstances is fine, even if it is not the cheapest option in town.

The 50% Meal Limitation

Under Section 274(n), business meals are generally deductible only at 50% of the unreimbursed cost. This applies whether you track actual receipts or use the IRS standard meal allowance. There is no longer a temporary 100% deduction for restaurant meals — that pandemic-era provision expired at the end of 2022.

Per Diem Rates: The Recordkeeping Shortcut

Rather than save every receipt, you can use the IRS's per diem method to substantiate lodging, meals, and incidental expenses. The IRS publishes annual rates; for the period beginning October 1, 2025 and running through 2026, the high-low method rates are:

A locality qualifies as "high-cost" when its federal per diem rate is $272 or more. The IRS updates the high-cost list each year, with most major metro areas (and many seasonal vacation spots during their peak months) on it.

Two practical wrinkles:

• On the first and last day of a trip, only 75% of the M&IE rate applies — so $64.50 in a high-cost city, $55.50 elsewhere.
• The 50% meal limitation still applies to the M&IE portion after you compute the per diem. The lodging portion is fully deductible.

Per diem is convenient but it has costs: it locks you out of deducting actual lodging if it exceeds the rate, and it cannot be used by self-employed taxpayers for their own lodging (only for meals and incidentals). Self-employed travelers who stay in expensive cities often save more by tracking actual receipts.

Who Can Actually Deduct These Expenses in 2026

This is where the rules diverge sharply depending on how you earn income.

Self-Employed (Schedule C, Schedule F, Partnership)

If you receive 1099 income or operate as a sole proprietor, partnership, or single-member LLC, you deduct qualifying travel directly on Schedule C (Form 1040) or Schedule F for farmers. Partnerships and S corporations deduct travel on the entity return, with the deduction flowing through to owners via K-1. The Tax Cuts and Jobs Act did not touch these deductions.

Employees

This is where things get hard. The TCJA suspended the miscellaneous itemized deduction for unreimbursed employee business expenses starting in 2018, and the One Big Beautiful Bill Act made that suspension permanent. Most W-2 employees cannot deduct unreimbursed travel on their federal return, full stop.

A few narrow exceptions survive:

• Qualified performing artists who work as employees for multiple employers, meet income tests, and have AGI below specified limits can take an above-the-line deduction.
• National Guard and military reservists can deduct travel more than 100 miles from home related to reserve duties.
• Fee-basis state and local government officials can deduct related expenses.

A handful of states — California, New York, Pennsylvania, and Minnesota among them — still allow unreimbursed employee business expense deductions on state returns, each with its own rules. Check your state.

The Accountable Plan: How Employees Still Get Reimbursed Tax-Free

For everyone else who works as a W-2 employee, the only way to recover travel costs without paying tax on them is an accountable plan reimbursement from your employer. Under Treasury Regulation 1.62-2, an accountable plan must meet three tests:

1. Business connection — the expense relates to services performed for the employer.
2. Substantiation — the employee provides amount, date, place, and business purpose, typically within 60 days of incurring the expense.
3. Return of excess — any advance not actually spent on business must be returned within 120 days.

When all three tests are met, reimbursements are tax-free to the employee and fully deductible to the employer (subject to the 50% meal cap). Miss any one and the entire arrangement becomes a non-accountable plan — reimbursements become taxable wages, with employment tax hitting both sides at a combined 15.3%.

Receipts matter. The IRS requires receipts for all lodging regardless of amount. Other expenses generally need a receipt only if they exceed $75, but detailed contemporaneous records — a notebook entry, an expense report line — are required for everything. A credit card statement alone is not enough. If audited, employees and the self-employed need to produce records showing each of the four elements: amount, time, place, and business purpose.

Where Mobile Workers Get Burned

A handful of patterns generate most of the audit losses in this area:

1. Treating a long assignment as a series of "temporary" rotations. A traveling nurse who takes back-to-back 13-week contracts at the same hospital cannot reset the one-year clock just because each contract is short. The IRS aggregates assignments at the same general location.

2. Maintaining a "home" the taxpayer does not actually live in. A consultant who keeps a parents' address as her home but spends 350 nights a year on assignment, with no duplicated living expenses, may be treated as itinerant. The three-factor test from Henderson is the IRS's tool here.

3. Commuting deductions disguised as travel. Driving from home to your regular workplace is non-deductible commuting, even if the workplace is 50 miles away. Section 162(a)(2) covers travel away from your tax home, not travel within it.

4. Failing the sleep-or-rest rule for meals. Long single-day trips that don't require an overnight stay get you no meal deduction, no matter how many miles you drove or how much you spent on lunch.

5. Letting an accountable plan slip into non-accountable status. Employers who pay flat travel allowances without substantiation, or who fail to require return of unspent advances, convert every dollar of reimbursement into taxable wages. The damage extends to payroll taxes for past quarters.

Records to Keep — and How to Keep Them

The IRS requires you to substantiate the amount, time, place, and business purpose of every travel expense. In practice, that means:

• A contemporaneous log (paper, app, or spreadsheet) capturing each day's travel: where you were, why you were there, who you met, what you spent.
• Receipts for all lodging, and for any other expense over $75.
• A mileage log if you use the standard mileage rate for a personal vehicle — date, business purpose, miles.
• Itineraries, calendar entries, or client communications that corroborate the business purpose.

Records should be kept for at least three years from the later of the return's due date or filing date. For travel expenses that contribute to a tax home determination — especially the duplication-of-expenses factor — keep records of your tax-home costs (rent, mortgage, utilities) as well, since the IRS may use them to test whether you actually have a home to be away from.

Accurate bookkeeping during the year, not at tax time, is what turns Section 162(a)(2) from a source of audit risk into a reliable deduction. The cost of reconstructing a year of travel from credit card statements after an IRS notice arrives is almost always higher than the cost of capturing the same information one trip at a time.

A Decision Tree for Your Next Trip

Before you book the next flight, run through the test:

1. Do you have a tax home? Identify it: the city or general area of your main place of business, by time, activity, and revenue. If you cannot identify one, you may be itinerant and entitled to no travel deductions.
2. Will you sleep somewhere other than your tax home? No overnight, no Section 162(a)(2) deduction for meals or lodging. Local mileage and transportation may still be deductible as ordinary business expenses, separately.
3. Is the assignment temporary? Realistic expectation of one year or less = temporary. More than one year = indefinite, no deductions, and your tax home moves.
4. Has the expectation changed? If a temporary assignment becomes likely to exceed a year, your deductible period ends on the date the expectation flips.
5. Are you self-employed or covered by an accountable plan? Self-employed people deduct directly. Employees need an accountable plan to recover costs tax-free, because TCJA + OBBBA permanently eliminated the unreimbursed employee deduction.
6. Do you have the records? Amount, time, place, business purpose. Lodging receipts always; other receipts over $75. Per diem can simplify M&IE substantiation but does not eliminate the business-purpose requirement.

Keep Your Travel Records Clean from Day One

Travel deductions reward people who track expenses as they happen, not those who try to reconstruct a year of trips when the IRS calls.
