Managing business travel costs starts with one critical number: the per diem rate. Whether you're a consultant billing clients for travel, a finance manager setting reimbursement policy, or a freelancer navigating tax deductions, understanding per diem rates for 2026 is essential. This guide covers everything — from IRS rates and German Verpflegungsmehraufwand to UK HMRC subsistence allowances — with practical tables you can use right now.

What Are Per Diem Rates?

Per diem (Latin: "per day") refers to fixed daily allowances paid to employees or contractors to cover work-related expenses while travelling away from their primary workplace. Instead of reimbursing every individual receipt — a taxi here, a sandwich there — organisations pay a flat daily rate.

Three core categories:

• Meals & incidentals — food, tips, laundry, and minor personal expenses
• Lodging — hotel or accommodation costs
• Incidental expenses — fees and tips to porters, baggage carriers, bellhops, hotel staff

Per diem rates serve two distinct purposes:

1. Tax deduction standard — the maximum you can deduct or reimburse tax-free
2. Internal reimbursement policy — what your company decides to pay (can be lower or higher, with tax implications above the official rate)

Why Per Diem Rates Matter in 2026

Rising hotel costs (+8.3% YoY in business travel hubs), inflation in meal prices, and post-COVID travel normalisation have pushed many official per diem rates upward in 2026. For finance teams, outdated rates mean either over-paying employees (taxable income above threshold) or under-reimbursing them (talent retention risk). For freelancers and self-employed professionals, using the correct 2026 rates is the difference between a clean tax filing and a costly audit.

Key changes in 2026:

• Germany: Verpflegungsmehraufwand unchanged at €14/€28 (day/full day)
• USA: IRS updated GSA rates effective October 2025 (FY2026)
• UK: HMRC benchmark scale rates reviewed September 2025
• Switzerland: New flat rates for 14 cantons
• Austria: Tagespauschale remains €26.40

USA: IRS Per Diem Rates 2026

The IRS publishes per diem rates through the General Services Administration (GSA) for domestic US travel. These rates apply to federal employees and are widely used as the standard for private sector reimbursements.

High-Low Method (FY2026)

The high-low substantiation method simplifies record-keeping for employers:

High-cost designations for FY2026 include: New York City, San Francisco, Washington DC, Los Angeles, Chicago, Boston, Miami, Seattle, and approximately 80 other high-cost localities.

Germany: Verpflegungsmehraufwand 2026 (Domestic)

Germany's Verpflegungsmehraufwand (meal expense allowance) is set by §4 EStG and §9 EStG. For 2026, the rates remain unchanged from 2024–2025:

Key rules:

• Absence is measured from your primary workplace or home
• Both days of a multi-day trip qualify for the €14 rate
• Employer can pay tax-free up to these limits; amounts above are taxable wages
• Self-employed deduct these amounts as Betriebsausgaben (business expenses)
• No receipt required — these are flat-rate (Pauschale) deductions

Austria: Tagespauschale 2026

Austria's Tagesdiäten are governed by the EStG (Einkommensteuergesetz):

Accommodation:

• Standard hotel allowance: €15 per night (actual receipts typically used)
• Government employees: fixed hotel rates per city

Austria's Tagespauschale is also available as a flat deduction for self-employed (Werbungskosten), with no receipts required up to the official rate.

Switzerland: Spesenpauschalen 2026

Switzerland has two systems: company expense policies (approved by cantonal tax authorities) and standard deductions for employed persons:

For business travellers:

Many Swiss employers use individual Spesenreglements approved by their cantonal tax office. Approved regulations allow higher flat rates (often CHF 25–35 for lunch in cities like Zurich or Geneva).

UK: HMRC Subsistence Rates 2026

HMRC publishes benchmark scale rates for meal allowances during business travel. Employers must check employees are actually away from their normal workplace.

Meal Allowances (Benchmark Scale Rates)

Overnight addition:

• £5 for incidental overnight expenses when staying away

Overseas Subsistence Rates (HMRC)

HMRC publishes country-specific rates for overseas travel. Key 2025/26 rates:

Employers can use these rates without requiring individual receipts if employees confirm travel took place.

France: Indemnités de déplacement 2026

French per diem rules are set by the URSSAF and labour agreements (conventions collectives):

Applicable when employee cannot return home for meals due to work distance.

Netherlands: Daggeldvergoeding 2026

Dutch meal reimbursement for business travel:

The Netherlands primarily uses a mileage rate system:

• €0.23/km tax-free for private car use (2026, same as 2025)
• Can be combined with actual hotel receipts

How to Calculate Per Diem: Step-by-Step

Method 1: Government Flat Rate (Most Common)

1. Identify destination country/city
2. Look up the applicable official rate for 2026
3. Count total travel days (departure + return + full days)
4. Apply 75% rule for first/last day (US) or specific domestic rules (EU)
5. Check if employer paid meals (reduces allowable amount)

Example:

A German consultant travels to London for 3 nights (Monday departure, Friday return).

- Monday (departure): €30 (partial day, UK rate)

- Tue, Wed, Thu (full days): 3 × €60 = €180

- Friday (return): €30 (partial day)

- Total: €240 Verpflegungsmehraufwand tax-free

Method 2: Actual Expense Method

Keep all receipts. Deduct or reimburse actual costs up to reasonable limits. More administrative work but allows higher deductions in expensive cities.

Method 3: Hybrid (Common in DACH)

Use flat rate for meals (no receipts needed), actual receipts for accommodation and transport.

Per Diem vs. Expense Reimbursement: Which Is Better?

Tax Treatment of Per Diem Payments

For Employees (Arbeitnehmer)

Per diem payments below the official rate are 100% tax-free — no income tax, no social security contributions. The employer deducts them as business expenses.

Per diem payments above the official rate are taxable income for the employee.

For Self-Employed / Freelancers

Claim per diem as Betriebsausgaben (business expenses) or Werbungskosten (income-related expenses) up to the official flat rate. No receipts required for the flat-rate portion.

Germany example:

Freelance consultant, 15 nights in Munich client site:

- 15 × €28 (full day) = €420 deductible, no receipts needed

- Plus actual hotel receipts

For Companies Setting Policy

You can set your policy below the official rate (saves cost) or above it (the excess is then taxable wage). Most companies aim for exactly the official rate for simplicity.

Common Per Diem Mistakes (And How to Avoid Them)

Mistake 1: Using Last Year's Rates

Per diem rates change annually. The German BMF publishes updates typically in November for the following year. IRS FY2026 rates took effect October 1, 2025. Using 2024 rates in 2026 can result in under-deducting or claiming non-compliant amounts. Fix: Bookmark the BMF website and GSA.gov for annual updates.

Mistake 2: Ignoring Meal Deductions

If your employer or client pays for a meal, you must reduce the flat rate. In Germany, each provided meal reduces the Verpflegungsmehraufwand by:

• Breakfast: 20% of the daily rate
• Lunch: 40%
• Dinner: 40%

For a full day (€28): provided lunch = €28 - €11.20 = €16.80 claimable.

Mistake 3: Applying Domestic Rates Abroad

Always use the destination country rate for international travel (Germany: BMF foreign rates). The domestic rate applies only when travelling within your home country.

Mistake 4: First/Last Day Confusion

In Germany, both the departure day AND return day each qualify for the partial rate (€14), even if you're only away for a few hours. A Monday-Friday trip = 5 × €14 (Mon, Fri) + 3 × €28 (Tue, Wed, Thu) = €112.

Mistake 5: Not Documenting Absence Duration

The flat rate only applies when you're away for more than 8 hours from your primary workplace. Keep calendar entries or travel confirmations showing departure/arrival times.

Frequently Asked Questions

Q: Can I claim per diem if I work from home?

A: Home-office workers can claim per diem when they travel to a client site or temporary workplace, provided they are away from their primary place of work for the required minimum time. For German freelancers, the primary workplace is typically the registered business address.

Q: What happens if my per diem exceeds the official rate?

A: Amounts above the official rate are taxable income for employees. For self-employed, you can deduct up to the official flat rate; amounts above require itemised receipts.

Q: Do per diem rates apply to day trips?

A: Yes. In Germany, if you're away from your workplace for more than 8 hours on a day trip (no overnight stay), you can claim €14. In the USA, the first/last day rate applies to any travel day.

Q: Can I use per diem AND claim hotel receipts?

A: Yes. Per diem typically covers meals and incidentals. Hotel costs are usually reimbursed separately based on actual receipts (or the accommodation flat rate in some systems).

Q: Are per diem rates different for different types of employees?

A: Official tax-free rates are the same for all employees in a given country. However, companies can set higher internal policy rates — the excess above the official rate simply becomes taxable wage.

Q: What about per diem for international conferences?

A: Use the destination country's rate for the days you are in that country. If you transit through multiple countries in one day, use the rate for the country where you spent the majority of time (or the last country visited, depending on national rules).
