Quick Answer: What 62 Cents a Mile Actually Nets

Two numbers decide your check, and only one of them is the CPM rate. The other is how many miles the carrier agrees to count.

Take a single filer running 2,400 paid miles a week at $0.62 per mile, 48 working weeks a year. That is 115,200 paid miles and $71,424 of gross pay. The table below runs it both ways after 2026 federal tax and FICA: no per diem program, then the carrier reclassifying pay at the $80 per day ceiling for 230 nights out.

	No per diem	Carrier per diem at the cap
Gross pay	$71,424	$71,424
Non-taxable reimbursement	$0	$18,400
W-2 taxable wages (Box 1)	$71,424	$53,024
Federal income tax	$6,883.28	$4,182.88
Social Security + Medicare	$5,463.94	$4,056.34
Annual take-home	$59,076.78	$63,184.78
Per working week (of 48)	$1,230.77	$1,316.35

The per diem program is worth $4,108 a year, about $85.58 a week, before the carrier’s admin fee. It does that without adding a single dollar to your pay. The trade is that your reported wages drop by $18,400, which is roughly 26% of your W-2.

State income tax is not in that table. Add your resident state’s rate on the taxable wage figure, which is a separate question covered further down.

The Miles Question Comes Before the Tax Question

Every per diem article on the internet starts at “gross pay.” That skips the part that moves the most money.

Loaded miles vs. deadhead

Loaded miles are the miles with freight on the trailer. Deadhead (or empty) miles are the ones getting you to the next pickup. Carriers handle deadhead three different ways: not paid at all, paid at a reduced rate, or paid only after a free-miles threshold (say, the first 50 empty miles are unpaid).

That policy is the single biggest source of week-to-week variance in a CPM driver’s pay. A recruiter’s CPM number tells you nothing about it.

Practical miles vs. HHG miles

HHG miles (household goods, sometimes called “short” miles) measure the shortest driving distance between the main post offices of the origin and destination cities. Practical miles measure the route a 53-foot trailer can legally take. The spread usually runs 5% to 8%.

Run the numbers on our driver. If those 115,200 miles are HHG miles, a carrier down the road paying practical routing at the same $0.62 would count roughly 6% more miles for identical freight: 122,112 miles, or $75,709. That is about $4,285 of extra gross pay, and roughly $3,000 of it survives tax.

Compare that to the $4,108 the per diem program saves. The mileage source is worth about the same money, and it comes with none of the downside: it raises your W-2 instead of shrinking it.

What CPM never pays for

Cents per mile pays for movement. It does not pay for detention at a shipper, loading or unloading, breakdowns, DOT inspections, or a 34-hour restart. Some carriers pay accessorials for these, most pay something for detention after a couple of hours, and none of it shows up in the CPM number.

There is no overtime premium either. The FLSA’s Motor Carrier Act exemption removes most interstate drivers from the overtime requirement, so hour 55 pays the same as hour 5.

Three questions to ask a recruiter

1. Which mileage source? Practical, HHG, or a specific software (PC Miler, Rand McNally) with which routing option.
2. Is deadhead paid, and from mile one? If not, what is the threshold and the rate?
3. What is the average weekly dispatched mileage for this fleet? Not the maximum, not “up to.” The average.

Answer those three and you can turn “up to 65 CPM” into an annual number you can budget against.

How Carrier Per Diem Programs Actually Work

A per diem program does not add money to your pay. Carriers rarely say that part plainly.

The carrier takes your existing CPM and relabels part of it. Most programs move $0.10 to $0.17 per mile out of taxable wages and into a non-taxable meals and incidentals reimbursement. Your gross CPM does not change. Your taxable CPM drops.

That reclassified portion is a reimbursement under an accountable plan, so it skips income tax withholding and FICA entirely. The general rules for accountable plans, substantiation, and what makes a stipend taxable are covered in our guide to per diem and stipends. This section covers only the trucking-specific parts.

The $80 per day ceiling

The IRS sets a special M&IE per diem rate for the transportation industry, higher than the standard CONUS rate. Under Notice 2025-54, it is $80 per day for travel inside the continental US and $86 per day outside it, for travel on or after October 1, 2025. The incidental-expenses-only rate is $5 per day.

That notice governs through September 30, 2026. The IRS reissues the transportation rate every October 1, so a successor notice takes over from there. Any article quoting $69 per day is running a rate that expired in 2024, and several of them are still ranking.

The ceiling is a per-day constraint, not a per-mile one. Two scenarios show how it bites:

• Typical program. At 14 CPM of reclassified pay and 2,400 miles across about 5.5 on-duty days, that is $336 a week, or roughly $61 per day. Comfortably under the cap.
• At the cap. Our worked example above reclassifies the full $80 per day for 230 nights, which is $18,400 a year and works out to about 16 CPM across 115,200 miles. That is the top of the typical range, and a driver running higher miles at that rate would push past $80 on some days. The excess has to be paid as ordinary wages.

Per diem also requires that the trip involve rest away from your tax home. Home time does not count, and partial travel days are typically prorated (carriers often use a three-quarter-day convention for the first and last day of a trip).

Net the admin fee first

Most carriers charge for running the program, either a fraction of a cent per mile or a flat weekly charge in the $5 to $15 range. At $10 a week over 48 weeks, that is $480 off the $4,108 saving, leaving about $3,628.

Ask for the fee in writing before you enroll, and check whether the program is opt-in, opt-out, or mandatory. Some carriers make it the default.

Company Driver vs. Owner-Operator: Opposite Answers

This is where most of the bad advice lives. The same $80 per day rate produces opposite outcomes depending on how you are paid.

W-2 company drivers cannot deduct per diem

Not reduced or limited. Zero.

The 2017 tax law suspended miscellaneous itemized deductions, and the One Big Beautiful Bill Act (P.L. 119-21) made that permanent, so nothing comes back in 2026. The IRS instructions for Form 2106 now limit the form to four groups: Armed Forces reservists, qualified performing artists, fee-basis state or local government officials, and employees with impairment-related work expenses. Truck drivers are not on that list.

If you are a W-2 driver, the only way to get the per diem benefit is an employer-run program. A tax preparer who offers to claim $64 a day on your 1040 as a company driver is describing a rule that stopped existing in 2018.

Owner-operators and lease drivers can

If you file Schedule C, you may use the $80 per day special transportation-industry rate instead of tracking actual meal receipts. Meals are normally 50% deductible, but §274(n)(3) substitutes 80% for individuals subject to DOT hours-of-service limits.

The math per qualifying day:

• $80 special M&IE rate
• times 80% (DOT hours-of-service limit)
• = $64 deductible per day

At 230 qualifying days, that is $14,720 off Schedule C net profit. Because it reduces net profit rather than itemized deductions, it cuts self-employment tax as well as income tax. Self-employment tax is 15.3% applied to 92.35% of net earnings, so the SE tax saving alone is roughly $2,080, with income tax savings at your marginal rate on top.

If that is your situation, our comparison of self-employment tax and employee tax covers the full picture, and quarterly estimated taxes covers the payment schedule that comes with it.

What a Smaller W-2 Costs You

Carrier recruiting pages stop at the weekly-take-home number. The other side of the ledger, ranked by how much it matters:

1. Your future Social Security benefit. This is the real one, and it is widely described wrong. Per diem is not wages, so it never reaches Box 3 and never lands on your Social Security earnings record. In our example that is $18,400 a year missing from the record used to compute your benefit.

What it does not do is cost you credits. In 2026 you earn one credit per $1,890 of covered earnings, and $7,560 gets you the maximum four for the year. A driver with $53,024 of taxable wages clears that many times over. The cost is a lower lifetime earnings record and therefore a smaller monthly check, not lost eligibility.

2. Loan and mortgage qualifying income. Lenders qualify you on documented wages: paystubs, W-2s, tax transcripts. A non-taxable reimbursement generally is not counted as qualifying income, and treatment varies between lenders and loan programs. Dropping your documented income by a quarter right before a mortgage application is an expensive way to save $85 a week.

3. Percentage-based 401(k) deferrals and match. If the plan defines compensation to exclude reimbursements, a 5% deferral now applies to a wage base that just fell by 26%. Your contribution and any percentage-based employer match shrink with it, quietly, without you changing a setting.

4. Unemployment and workers’ comp. Both are calculated on wage bases defined by state rules. Lower reported wages can mean lower benefits if you get laid off or hurt.

A note on “no tax on overtime.” The 2026 deduction under §225 keys off overtime required by section 7 of the FLSA. Motor Carrier Act-exempt drivers do not earn FLSA overtime, so a CPM company driver generally gets nothing from it no matter how many hours the logbook shows. Our explainer on the overtime tax deduction covers who does qualify.

Running Your Own Numbers

A CPM driver has no salary and no hourly rate, so the conversion has to happen before you touch a calculator.

Step 1: annualize the miles. Average weekly paid miles × CPM × working weeks. Use the recruiter’s average dispatched mileage, not the top end, and subtract the weeks you take off.

Step 2: split out the per diem. If you are enrolled, the reclassified portion is not wages. Enter the taxable remainder as your salary figure and the per diem portion as non-taxable additional income. Pay44 has a flag for exactly that, so you can see both halves of the check in one place instead of guessing at the withholding.

Step 3: pick your resident state. A driver’s state income tax generally follows the state of residence rather than the states rolled through, which is why running 20 states a month does not mean 20 state returns. Reciprocity and non-resident filing rules exist for some situations, so check yours if you are unsure. Pay44 covers all 50 states, so you can compare a Texas domicile against a Pennsylvania one on the same offer.

Step 4: run it twice. Model the offer with per diem and without, then subtract the admin fee from the difference. That number is what the program is actually worth to you, and it is the number to weigh against a smaller W-2.

For the pieces around the edges, the calculator library has tools for self-employment tax, quarterly estimates, and reconciling Box 1 against your gross pay. If you want the numbers with you at the truck stop, the app is available for iOS and Android.

One last scope note, because it trips people up: the IRS standard business mileage rate has nothing to do with CPM pay. That rate is for deducting business use of your own vehicle. Miles driven in your employer’s truck are ordinary wages, and no per-mile deduction applies to them.

Frequently Asked Questions

What is the truck driver per diem rate for 2026?

$80 per day inside the continental US and $86 per day outside it, set by IRS Notice 2025-54 for travel on or after October 1, 2025. That notice runs through September 30, 2026. The IRS resets the transportation-industry rate every October 1, so confirm the current notice before you rely on the number.

Is per diem pay taxed for truck drivers?

No, not when a carrier pays it under an accountable plan within the federal rate. It is a reimbursement rather than wages, so it does not appear in Box 1, Box 3, or Box 5 of your W-2 and nothing is withheld from it. Anything paid above the federal rate, or paid without the required documentation, becomes taxable wages.

Can company drivers still deduct per diem on their taxes?

No. The deduction for unreimbursed employee expenses was suspended by the 2017 tax law and made permanent by the One Big Beautiful Bill Act. Form 2106 is now limited to Armed Forces reservists, qualified performing artists, fee-basis state or local officials, and employees with impairment-related work expenses. A W-2 driver's only route to the benefit is an employer-run per diem program.

Can owner-operators deduct per diem?

Yes. Owner-operators and other self-employed drivers filing Schedule C can use the $80 per day special transportation-industry rate, limited to 80% rather than 50% because they are subject to DOT hours-of-service rules. That works out to about $64 of deduction per qualifying day, and it reduces both income tax and self-employment tax.

Does per diem pay hurt your Social Security?

It lowers your future benefit amount, not your eligibility. Per diem is not wages, so it never reaches your Social Security earnings record. But at $1,890 of covered earnings per credit in 2026, you still earn all four annual credits easily on the taxable half of your pay. The real cost is a smaller lifetime earnings record, which means a smaller monthly check later.

Will per diem make it harder to get a mortgage or car loan?

It can. Lenders generally qualify you on documented W-2 wages and paystubs, and a non-taxable reimbursement usually is not counted as qualifying income. Treatment varies by lender. If you plan to buy a house in the next year or two, ask the lender how they handle per diem before you enroll.

What is the difference between practical miles and HHG miles?

HHG (household goods, or "short") miles measure the shortest distance between the main post offices of the origin and destination cities. Practical miles follow the route a truck can actually and legally drive. Practical routing typically pays 5% to 8% more miles for identical freight, so always ask a recruiter which source the carrier uses.

Do truck drivers get overtime pay?

Usually not. The Motor Carrier Act exemption removes most interstate drivers from the FLSA overtime requirement, so hours past 40 generally earn the same cents-per-mile rate. That also means the 2026 no-tax-on-overtime deduction, which applies to FLSA-required overtime, typically does nothing for a cents-per-mile driver.
