Is Per Diem Taxed? 2026 IRS Rules

Short answer: it depends on your employer’s plan structure and whether the per diem exceeds IRS-published rates.

Scenario	Taxable?
Per diem within IRS/GSA rates + accountable plan	NO — not taxable
Per diem exceeding IRS/GSA rates + accountable plan	Excess is taxable wages
Per diem under unaccountable plan	Fully taxable as wages
Per diem for federal employees (within GSA rates)	Not taxable
Per diem for military (within DTMO rates)	Not taxable
Per diem to independent contractors	Treated as 1099 income (taxable)

The IRS framework is in Publication 463 (Travel, Gift, and Car Expenses). Most properly-structured employer per diems are non-taxable to employees — but the rules matter, and exceeding the federal per diem rates triggers reporting requirements.

What is per diem?

“Per diem” (Latin for “per day”) is a daily allowance that an employer pays an employee for travel expenses — lodging, meals, and incidentals — instead of reimbursing exact expenses with receipts.

Two main approaches:

Reimbursement model: Employee submits receipts, employer pays exact expense amount. Always non-taxable if business-related.
Per diem model: Employer pays a fixed daily allowance. Tax treatment depends on the plan structure.

Per diem simplifies administration (no receipt processing) and lets employees pocket savings if they spend less than the allowance. It can be standard for traveling sales reps, truck drivers, federal employees, military, consultants, and others with frequent travel.

The two types of per diem plans

Accountable Plan (non-taxable when properly run)

An “accountable plan” under Treasury Reg §1.62-2 must meet three requirements:

Business connection: Expenses must be for actual business travel
Substantiation: Employee must provide records of time/place/business purpose within a reasonable time (typically 60 days)
Return of excess: Employee must return any per diem in excess of substantiated expenses within a reasonable time (typically 120 days)

If all three conditions are met AND the per diem is within IRS/GSA rates, the entire per diem is non-taxable and isn’t reported on the W-2.

Non-accountable Plan (fully taxable)

If the employer’s plan fails any of the three requirements (e.g., employee doesn’t return excess, no business records), the entire per diem becomes taxable wages. It must be:

Included in W-2 Box 1 (taxable wages)
Subject to income tax withholding
Subject to FICA / Medicare withholding

Even legitimate business travel under a non-accountable plan is taxable — the structural failure of the plan converts the per diem into compensation.

IRS / GSA per diem rates for 2026

The federal government publishes per diem rates by location for the continental United States (“CONUS”), with separate tables for international and out-of-state locations (“OCONUS”).

Standard CONUS rate (areas not specifically listed)

Lodging: $107/night
Meals & Incidental Expenses (M&IE): $68/day
Total: $175/day

High-cost cities (examples)

Higher rates apply in cities like:

New York City, NY: ~$346/day total
San Francisco, CA: ~$334/day total
Boston, MA: ~$305/day total
Washington, DC: ~$315/day total
Chicago, IL: ~$273/day total

Current 2026 rates: GSA Per Diem Rates.

Per diems within these published rates are non-taxable when paid under an accountable plan.

Special meal & incidental expense (“M&IE only”) rate

$68/day standard
$80/day in high-cost areas
Used when only meals are reimbursed (lodging billed separately)

First and last day of travel

First and last days are typically prorated at 75% of the M&IE rate (since the traveler isn’t gone the full day).

High-low method (simplified)

Instead of looking up rates by city, employers can use the “high-low” simplified method:

High-cost locations: $319/day ($278 lodging + $74 M&IE)
All other locations: $225/day ($201 lodging + $64 M&IE)

The employer publishes which locations qualify as high-cost; this list is updated annually by the IRS in a revenue procedure. Easier administration but slightly less precise than location-specific rates.

What happens if per diem exceeds IRS rates?

If your employer pays you a per diem that exceeds the IRS/GSA rate for your travel location, the excess is treated as taxable wages:

Included in W-2 Box 1
Subject to income tax withholding
Subject to FICA

The portion within the IRS rate remains non-taxable; only the excess is taxable. This requires the employer to track and split.

Example: Employer pays $250/day for a trip to Chicago (IRS rate $273/day). All non-taxable.

Example: Employer pays $400/day for a trip to a standard CONUS area (IRS rate $175/day). $225/day is taxable wages.

Per diem for truck drivers

Long-haul truck drivers have special per diem rules under Department of Transportation guidelines. The standard daily M&IE rate is $80/day for drivers covered by DOT hours-of-service rules.

For self-employed truckers (1099 contractors), the per diem is a deductible business expense on Schedule C, with the entire $80/day deductible. (Pre-2017, only 80% of M&IE was deductible; the OBBB Act and prior legislation has tweaked this — verify current year rate.)

W-2 truck drivers receiving employer per diem within IRS rates: non-taxable, as above.

Per diem for federal civilian employees

Federal civilian employees traveling on official business receive per diem at GSA published rates. These are always within the IRS rates (since they ARE the IRS reference) and not taxable.

Government per diem payments don’t appear on the W-2 (or appear in informational boxes only, not as taxable income).

Per diem for military

Service members on official travel (TDY — Temporary Duty) receive per diem at rates set by the Defense Travel Management Office (DTMO). These rates align with GSA in CONUS.

Military per diem is non-taxable when within authorized rates. The Defense Finance and Accounting Service (DFAS) reports these payments separately and they don’t appear as taxable W-2 income.

For active duty service members in combat zones, additional tax-free pay rules apply under IRC §112.

Per diem for independent contractors / 1099

If you’re a self-employed individual receiving per diem from a client (or paying yourself per diem from your own business):

Receiving per diem from a client: It’s gross 1099 income on Schedule C. You then deduct actual travel expenses (meals, lodging) against it. The per diem isn’t separately favored.
Paying yourself per diem from your business: You deduct actual travel expenses, not the per diem itself, on Schedule C.
Using the federal M&IE rate: As a self-employed business owner, you can use the federal M&IE rate ($68/day standard) as the deemed meal expense without keeping individual meal receipts — useful simplification.

What to do if your per diem is taxed when it shouldn’t be

If you believe your employer is treating per diem incorrectly:

Review your W-2 Box 1 against your gross wages — is per diem included?
Ask HR/payroll whether the company runs an accountable or non-accountable plan
Check whether the rates exceed GSA per diem
If misclassified, request a corrected W-2 (Form W-2c)

If you’ve already filed and discover the issue, you can file an amended return (Form 1040-X) for the affected years.

Recordkeeping for per diem travel

To maintain accountable plan status, keep records of:

Date of travel
Destination (city/state)
Business purpose (meeting, conference, client visit)
Hours traveled
Mileage if driving

For lodging within the per diem cap, you don’t need to keep individual receipts — the per diem is deemed sufficient.

For lodging exceeding the per diem cap (where you ask for reimbursement of actual cost), you do need receipts.

Bottom line

Per diem properly paid under an accountable plan within IRS rates is not taxable to the employee. The vast majority of corporate, government, and military per diems work this way.

If you’re seeing per diem amounts showing up as taxable wages on your W-2, it usually means either:

The plan is non-accountable (failed one of the three tests)
The per diem exceeds federal rates and only the excess is taxed
A reporting error occurred (request correction)

For 1099 contractors, per diem received is income; per diem you pay yourself isn’t separately tracked — what matters is your actual deductible travel expenses.

FAQs

Q: My employer pays me $50/day per diem on the road. Is that taxable? If your plan is accountable and $50/day is at or below the IRS rate for your travel city, no. If the plan is non-accountable, yes. Check with HR.

Q: I’m a truck driver. Can I deduct meals beyond what my employer pays as per diem? Generally no — the IRS per diem method substitutes for actual expense tracking. Employer per diem within rates is non-taxable; you can’t double-deduct. Self-employed truckers can use the $80/day M&IE rate.

Q: My employer reimburses my actual receipts. Is that taxable? No — that’s not per diem, it’s expense reimbursement. As long as the expenses are business-related and properly substantiated, it’s not taxable.

Q: Is the GSA per diem rate the same nationwide? No. GSA publishes location-specific rates. New York City is around $346/day; rural Kansas is around $175/day (standard rate). Look up your specific city at GSA.gov.

Q: I get $100/day in cash from my employer for daily expenses. Is that per diem? It depends on the plan structure. If your employer is treating it as per diem under an accountable plan, with substantiation requirements, then it can be non-taxable. If you don’t return excess and there’s no business substantiation, it’s a non-accountable plan = taxable wages.

Q: I work remotely and travel occasionally to the home office. Is per diem from those trips taxable? For occasional business travel, yes — per diem under an accountable plan is non-taxable. The rules don’t change based on remote work status.

Q: Per diem vs. mileage reimbursement — which is better? They cover different things. Per diem covers lodging + meals + incidentals during travel. Mileage covers vehicle expense (2026 IRS standard mileage: 70 cents/mile for business). Many travelers receive both — both are non-taxable when paid under accountable plans within IRS rates.

Q: Can my employer pay both per diem AND reimburse my hotel separately? Yes, this is the “M&IE-only” per diem method. The employer pays $68/day (standard) or $80/day (high-cost) for meals and incidentals, and reimburses actual lodging costs with receipts. Both can be non-taxable under accountable plans.
