Per diem is one of the biggest factors a traveling lineman considers before accepting a call. It can make the difference between a job that's worth the drive and one that barely covers your expenses. But per diem rules aren't always straightforward — rates vary by local, eligibility depends on distance thresholds, and the tax implications aren't always obvious. Here's what you need to know.

What Is Per Diem?

Per diem — Latin for "per day" — is a daily allowance paid to workers who travel beyond a certain distance from the union hall to work. It's meant to offset the cost of lodging, meals, and incidental expenses while you're working away from home.

For IBEW outside line work, per diem is negotiated as part of each local's collective bargaining agreement. That means the rate, eligibility rules, and payment structure vary from local to local. There is no single universal IBEW per diem rate — it depends entirely on which local's jurisdiction you're working in.

How Per Diem Rates Are Set

Per diem rates are established in the local's working agreement with signatory contractors. The agreement specifies a daily dollar amount, typically broken out as a flat rate per day worked.

Rates across the country vary significantly. Some locals set per diem in the range of $50–$75 per day, while others — particularly in high cost-of-living areas or remote jurisdictions — may go well above $100 per day. The rate reflects the local cost of living, housing market, and what the parties negotiated.

Per diem is typically stated as a daily amount and paid for each day you report to work. Some agreements also include per diem for travel days (the day you drive to the job and the day you drive home), but this isn't universal.

Members of Union Line Calls can compare per diem rates across locals through our contract information pages, accessible via the Hall Directory.

Who Qualifies for Per Diem?

Not every worker on every job receives per diem. Eligibility is based on how far you live (or how far the hall is) from the job site. The specifics depend on the agreement, but here's the general framework.

Distance threshold. Most agreements define a radius around the reporting location or the union hall — commonly somewhere between 50 and 75 miles, though this varies. If you live (or the hall is located) outside that radius, you qualify for per diem. If you're inside the radius, you don't.

Travelers vs. local members. If you're a traveler from another local, you almost always qualify for per diem, since by definition you've traveled beyond the local area. Local members may or may not qualify depending on where the specific job site is relative to their home and the agreement's distance rules.

Residency vs. hall location. Some agreements base the distance calculation on your permanent home address, while others base it on the distance from the union hall to the job site. This distinction matters — read the agreement or ask the dispatcher if you're unsure.

Per Diem and Taxes

This is where it gets important. Per diem payments can be either taxable or non-taxable depending on how they're structured and whether you meet certain IRS criteria.

Non-taxable per diem. Under IRS rules, per diem paid to workers with a "tax home" (a permanent residence they maintain) who are working at a temporary job site away from that home is generally not taxable — as long as the rate doesn't exceed the federal per diem limits set by the GSA (General Services Administration). This is a significant financial benefit. Non-taxable per diem is essentially money in your pocket that doesn't show up on your W-2.

Taxable per diem. If you don't maintain a tax home (for example, if you've been on the road continuously and don't have a permanent residence), the IRS may consider you an itinerant worker, and per diem becomes taxable income. The rules here are nuanced and individual circumstances vary.

This is not tax advice. Tax home rules, temporary vs. indefinite work assignments, and per diem taxation are complex. The IRS has specific criteria that depend on your individual situation. Consult a tax professional who understands traveling construction workers — this is specialized enough that a general tax preparer may not get it right.

What Per Diem Is Meant to Cover

Per diem is designed to cover three categories of expenses while you're working away from home.

Lodging. A hotel, motel, RV park, or other temporary housing near the job site. Many travelers pull RVs or campers to reduce lodging costs, which means more of the per diem stays in their pocket.

Meals. Food and drink while on the road. This is straightforward — you have to eat, and eating out every day adds up.

Incidentals. Laundry, tips, and other small expenses associated with living on the road.

The per diem rate is a flat amount — you don't have to submit receipts or justify your spending. If you can keep your daily expenses below the per diem rate, the difference is yours.

How Per Diem Affects Your Take-Home

When comparing calls across different locals, per diem can significantly change the math. A job with a slightly lower scale rate but strong per diem might put more money in your pocket than a higher-scale job with no per diem — especially if the per diem is non-taxable.

Here's a simplified example. Suppose Local A offers $55/hour with $100/day per diem, and Local B offers $60/hour with no per diem. On a 10-hour day, Local A pays $550 in wages plus $100 per diem ($650 total, with the $100 potentially non-taxable). Local B pays $600 in wages, all taxable. Depending on your tax bracket, Local A could net you more.

This is why experienced travelers don't just look at scale rate — they evaluate the full package: scale, per diem, overtime likelihood, benefits, and cost of living in the area.

Per Diem Tips for Travelers

Read the agreement before you go. Don't assume every local's per diem works the same way. Check the rate, the distance threshold, whether travel days are covered, and any special conditions. Members can access contract details through Union Line Calls.

Ask the dispatcher. When you get a call, ask whether per diem applies to the specific job. Sometimes different jobs within the same local's jurisdiction have different per diem eligibility based on location.

Keep records. Even if per diem is non-taxable, keep a log of your work locations, dates, and expenses. If you're ever audited, documentation protects you.

Factor in real costs. Per diem looks great on paper, but consider the actual cost of living in the area. $85/day per diem in a town where the cheapest hotel is $120/night is a different situation than $85/day where you can park your camper for $30/night.

Maintain your tax home. If you're a regular traveler, maintaining a permanent residence (and being able to prove it) is important for keeping per diem non-taxable. This means paying rent or a mortgage, maintaining a mailing address, and returning home between jobs. Talk to a tax professional about your specific situation.

Comparing Per Diem Across Locals

One of the advantages of having contract data in one place is the ability to compare per diem rates across locals before deciding where to travel. Rather than calling multiple halls or digging through individual websites, you can review the key terms side by side.

Union Line Calls tracks contract information including per diem, scale rates, and benefit contributions for locals across the country. Browse the Hall Directory to find locals with contract data available, and check the Job Board to see which locals are actively posting calls. To understand what those call postings include, see How IBEW Job Calls Work. Check Book Status to see how quickly you might get dispatched, and read our guide on Understanding IBEW Book Status for what the numbers mean.
