Is per diem taxable for electricians?

Per diem is not taxable for an electrician when four things line up: you have a tax home, you're working far enough from it that you have to sleep over, the job is expected to last a year or less, and the company pays it under an accountable plan at or under the federal rate. Miss any one and some or all of it is wages. The rules are in IRS Publication 463.

The tax home is the piece most people skip, and it's where a lot of traveling hands get caught. For the pay side of a road job (rate, overtime, how long it runs), see the traveling electrician guide.

This is the general federal rule. Your situation may have a wrinkle, so run it by a tax pro before you file.

01The quick check

Run your job through these five questions. A "no" on any of them means at least part of your per diem is taxable.

The rest of this post explains each line.

02What is your tax home?

Your tax home is generally "your regular place of business or post of duty," not just where your family lives. For a traveling hand with no regular shop, it's usually the home he keeps up and comes back to.

Pub 463 gives three factors for a worker with no main place of business:

1. You do part of your work in the area of your main home and live there while you do.
2. You have living expenses at that home that you double up on when work keeps you away.
3. You haven't abandoned the area. Your family lives there, or you often stay there.

Meet all three and that home is your tax home. Meet two and it may be, depending on the facts. Meet only one and the IRS calls you itinerant: "your tax home is wherever you work," and you're never away from home for tax purposes.

In the trade, that's the hand who sold the house, lives in his camper and follows the work. He may be fine on the road, but he likely has no tax home to be away from, and per diem paid to him can be taxable wages. If that's you, sort it out before tax season, not after.

03Does driving home every night count?

No. You have to be away long enough that you need sleep or rest to do the job.

Pub 463 says the trip has to be substantially longer than an ordinary workday and long enough that you need sleep or rest. It adds that the rest requirement "isn't satisfied by merely napping in your car."

So a J-man who drives 80 miles each way and sleeps in his own bed isn't traveling for tax purposes. A company can still pay him something for the drive, but it's taxable pay, not tax-free per diem. Some shops and union agreements pay a daily travel allowance at a set mileage. That's a pay rule, not a tax rule. The per diem pay rules post covers how those mileage lines work.

04What happens when the job runs past a year?

A job at one location expected to last more than a year is not temporary, and per diem on it is taxable from day one.

Pub 463 draws the line this way: a job "realistically expected to last (and does in fact last) for 1 year or less" is temporary. A job "realistically expected to last for more than 1 year" is indefinite, even if it ends early.

Pub 463 even uses a construction worker for the example. He lives and works in Los Angeles and takes a job in Fresno scheduled to run 8 months. It actually runs 10. The job is temporary, and his tax home stays in Los Angeles.

Now the trap. In Information Letter 2019-0003, IRS Chief Counsel explained that a job first expected to run a year or less, which later is expected to run longer, is temporary only "until the date the taxpayer's expectation changes." From that date, the job site becomes your tax home. The letter also says the IRS can't waive the rule. It's in the tax code, so only Congress can change it.

That's how a data center campus catches people. Phase 1 is expected to run nine months. In month seven, everyone knows Phase 2 starts right behind it at the same site. From the day that's clear, per diem there is taxable. Ask the company how long the job is expected to run before you go, and ask again every time the schedule moves.

05How does per diem show up on your W-2?

Per diem at or under the federal rate stays out of box 1 and isn't taxed. When the company pays more than the federal rate, the part up to the rate shows in box 12 with code L, untaxed, and the excess goes in box 1 as wages.

The yardstick is the GSA rate for where the job is. For FY2027 (Oct. 1, 2026 to Sept. 30, 2027), the standard rate in most counties is $113 lodging plus $68 meals and incidentals, $181 a day. Many cities run higher.

A worked example, our math. Say you get $200 a day, 7 days, on a job in a standard-rate county:

Only the $1,596 is taxed. The rest stays out of your wages.

If the company pays the hotel and gives you meal money only, the yardstick is the meals and incidentals part of the rate, not the full $181. Say they give you $100 a day for meals in a county where the federal M&IE rate is $68. Then $32 a day is wages, $224 over a 7-day week.

Pub 463 also requires the company to run the per diem through an accountable plan. You prove the dates, place and business purpose of your travel, usually through your timesheets, and you don't keep money you weren't owed. Under a plan like that, a per diem at or under the federal rate counts as accounted for without receipts for every meal.

06Is a rate cut paid back as per diem legal?

It's a red flag. The IRS says a setup that pays expenses by "reducing the amount reported as your wages, salary, or other pay" is a nonaccountable plan, which means the whole per diem is wages.

Here's what the swap looks like on a 60-hour week, our math:

Offer B looks like a tax break. On the check as written, it pays $100 a week less, because time and a half is figured on $35 instead of $45. Anything figured on your wages, like a 401k match, figures on the smaller number. And by the IRS's own wording, the $600 is wages anyway.

Real per diem goes to hands who are actually traveling, on top of a real rate. If the shop pays the same "per diem" to the guy who lives five minutes from the gate, it's pay with a different name. Your overtime rights on a road job are covered in electrician rights on the job.

07Can you deduct travel costs if the company pays no per diem?

For most W-2 electricians, not on the federal return right now.

Pub 463 (2025) says that because miscellaneous itemized deductions are suspended, most employees can't use Form 2106 to deduct unreimbursed travel. The exceptions are narrow: Armed Forces reservists, qualified performing artists, fee-basis state or local government officials, and employees with impairment-related work expenses.

That changes how you should compare offers. A travel job that pays a higher rate and no per diem means you pay the hotel out of taxed dollars. A lower rate with real per diem can come out ahead. The travel vs local pay math puts both on one page.

Before you weigh a road job, check what your rate should be at home. Run your Pay Check to see what electricians with your license make near you. It takes about a minute, and your boss never hears about it.
