What Counts as a Tax Home for a Traveling Tradesperson?

The word "home" is doing unusual work here. It is not your house, and for a traveler the two are often a thousand miles apart.

Publication 463 splits it three ways:

• You have a regular place of business — that area is your tax home.
• Your work has no regular location, but there is a place you regularly live — that place may be your tax home, if you meet the test in the next question.
• You have neither — you are considered an itinerant, and your tax home travels with you to wherever you happen to be working.

That last case is the one that catches road hands out, because "away from home" stops meaning anything if home is wherever you are standing.

For someone with no regular place of business, Publication 463 looks at three factors about the place you call home:

• You do part of your work in that area, and use that home for lodging while you do.
• You have living expenses at that home that you are duplicating because work takes you away from it.
• You have not abandoned it — family lives there, or you use it often yourself.

Meet all three and that home is generally your tax home. Meet two and it turns on the facts and circumstances. Meet one and you are generally treated as an itinerant.

The two-out-of-three case is where a lot of travelers actually sit, and it is why two people on the same crew, on the same job, can end up with different answers.

The three factors, from Publication 463, when you work in more than one place:

• The total time you ordinarily spend working in each place.
• The level of your business activity in each place.
• Whether the income from each place is significant or insignificant.

Time is usually the heaviest of the three, which is why a day-by-day record of where you actually worked is worth more than a memory in March. Most travelers can name the jobs; almost nobody can name the dates.

This is the most consequential rule on the page, and it turns on expectation, not the calendar:

• Temporary — realistically expected to last one year or less, and it does.
• Indefinite — realistically expected to last more than one year, whether or not it actually does.

If your expectation changes partway through, Publication 463 treats the job as temporary up to the point it changed and indefinite from then on.

So a nine-month turnaround that gets extended to fifteen is treated differently from a fifteen-month job you took knowing it was fifteen months — same total time on site, different answer. The date your expectation changed is a fact worth writing down when it happens.

Publication 463 calls an account book, diary, log, trip sheet or statement of expense an adequate record, backed by documentary evidence — receipts — for lodging and for any expense of $75 or more.

The piece most travelers do not have is the simplest one: a day-by-day log of where they were. It is the same record that supports the tax-home question, the per-diem question and the mileage question, and it is the one thing that cannot be reconstructed honestly at the end of the year.

That is the whole reason this question matters to someone on the road rather than to an accountant. The same $120 a day is a reimbursement in one situation and taxable pay in another, and the thing that decides it is not the money — it is where your tax home sits.

The mechanics of the allowance itself are on the per-diem page.

We are deliberately not answering this one, and it is worth saying why rather than just going quiet.

Self-employed and 1099 travelers are treated very differently from W-2 employees, and the rules for employee unreimbursed expenses have changed before and are scheduled to change again. Anyone who gives you a flat answer to this without asking how you are paid and which tax year you mean is guessing.

What we will say is the useful half: the record is the same either way. Where you worked, which days, how far you drove, what you spent. That evidence is worth having before you know which rule applies to you, and it is worthless to build after the fact.
