Business Travel Expenses in Germany: Per Diem Rates, Mileage Allowance, and Tax Deduction Rules

Business Travel Expenses in Germany: Complete Guide to 2026 Deductions

Business travel (Dienstreise) is one of the most tax-efficient deductions available to German business owners and employees. Germany offers generous per diem rates (Pauschalen) and mileage allowances that require minimal documentation. Understanding these rules and maximizing your deductions is critical for profitability — especially for companies with frequent travel.

Verpflegungsmehraufwand (Per Diem) — 2026 Rates

The German tax code allows a per diem (Verpflegungsmehraufwand) — a daily allowance for meal expenses during business travel. These are flat rates with no receipts required:

• €14/day for travel lasting 8-24 hours (partial day away from home office)
• €28/day for travel lasting ≥24 hours (full day away or overnight stay)
• €14 each on arrival and departure days (not the full €28)

Example: 3-Day Business Trip

You travel Monday morning and return Thursday evening. Deduction: Monday €14 (arrival day) + Tuesday €28 (full day) + Wednesday €28 (full day) + Thursday €14 (departure day) = €84 total Verpflegungsmehraufwand.

The 3-Month Rule (Dreimonatsfrist) — Critical Limit

The per diem allowance has a major restriction: the 3-month rule. Once you've been assigned to the same work location (Tätigkeitsstätte) for more than 3 months, Verpflegungsmehraufwand is no longer deductible:

• First 3 months at a location: Verpflegungsmehraufwand fully deductible
• After 3 months: per diem allowance no longer available; only actual meal expenses count
• The 3-month period resets if you leave and later return to the same location
• Daueraufenthaltsort (permanent workplace) after 3 months: treated as your regular office

Reducing Per Diem for Meals Provided by Employer

If your employer provides meals during the trip (hotel breakfast included, office lunch provided), you must reduce your per diem claim:

• Breakfast provided: Reduce per diem by €20 (20% of €100 daily meal value)
• Lunch provided: Reduce per diem by €40 (40% of €100 daily meal value)
• Dinner provided: Reduce per diem by €40 (40% of €100 daily meal value)
• Multiple meals on same day: cumulative reduction (e.g., breakfast + lunch = €60 reduction)

Example: €28 per diem day, but lunch was provided. Deductible per diem: €28 - €40 = €0 (you can't claim less than zero, so zero reduction to €28 is the minimum).

Mileage Allowance (Kilometer Pauschale)

If you use your own car for business travel, you can deduct mileage:

• €0.30 per km for the first 20 km of your commute
• €0.38 per km from the 21st km onward (reduced rate for longer distances)
• One-way distance counted (e.g., 50 km commute = 50 km, not 100 km)
• This applies only to your own vehicle (not rental cars or taxis)

Example: 60 km commute to a client. Deduction: (20 km × €0.30) + (40 km × €0.38) = €6.00 + €15.20 = €21.20 per trip.

Actual Travel Costs (Public Transport, Flights)

For trains, buses, flights, and taxis, you deduct actual costs:

• Train tickets: deduct full cost (1st or 2nd class if business-justified)
• Flights: deduct full ticket cost plus taxes/fees
• Rental cars: deduct full rental cost plus fuel and tolls
• Taxis: deduct full fare for business trips
• Parking and tolls: separate deduction (included in Reisenebenkosten if part of car rental)

You need receipts/tickets for all public transport and flight costs. Keep digital copies in your expense management software.

Overnight Accommodation (Uebernachtungskosten)

Lodging costs are deductible based on actual expenses with documentation:

Domestic Overnight Stays

• Deduct actual hotel costs (receipt required)
• No limit on per-night amount; reasonableness applies
• €50-150/night for business travel is typical in major German cities
• Higher-end hotels (€200+/night) require justification

International Overnight Stays

• Germany publishes a BMF table with maximum per-night rates by country
• You can deduct up to the country limit (or actual cost, whichever is lower)
• For hotels in expensive cities (London, Paris, Zurich), the BMF table covers ~€100-150/night
• Rates are updated annually by the Federal Ministry of Finance (BMF)

Travel Incidentals (Reisenebenkosten)

Additional travel expenses are deductible when supporting business travel:

• Parking and tolls: Fully deductible
• Airport/train station lounge access: Deductible for business class parity
• Luggage or equipment transport: Deductible if business-related
• Travel insurance (per trip): Deductible
• Visa fees for international travel: Deductible
• Tips and gratuities: Deductible if part of documented service charges
• Car rental insurance/damage waiver: Fully deductible

Employer Reimbursement — Tax-Free if Within Per Diem Limits

If your employer reimburses you for travel expenses within the official per diem rates, the reimbursement is tax-free (no income to report):

• Reimbursement up to €14/€28 per diem: tax-free
• Reimbursement for actual transport costs (with receipts): tax-free
• Reimbursement for actual hotel costs (with receipts): tax-free
• Reimbursement exceeding these limits: taxable as income to the employee

Example: You submit €200 in actual hotel receipts. Employer reimburses €200. This is tax-free. If they reimburse €250 (without receipts), the extra €50 is taxable income.

Self-Employed vs. Employee Treatment

The rules differ slightly depending on your tax status:

Employees (Angestellte)

• Claim per diem on income tax return (Anlage N form)
• Claim actual transport and lodging costs on income tax return
• Employer reimbursement within limits is tax-free (don't report as income)
• No Vorsteuerabzug (VAT recovery) available — employee's personal tax return

Self-Employed (Freiberufler, Gewerbetreibende)

• Claim all travel deductions on business tax return (Anlage S form)
• Recover 100% of Vorsteuerabzug (input VAT) on lodging, transport, meals
• Per diem allowances still apply (same €14/€28 rules)
• Higher overall tax advantage due to VAT recovery

International Per Diem Rates (Top 10 Countries)

These rates are updated annually by the BMF (Federal Ministry of Finance). Check the latest table on the Bundeszentralamt fuer Steuern website.

Double Household (Doppelte Haushaltsführung) — Extended Deduction Opportunity

If you maintain a double household (one residence for family, another for work), additional deductions apply:

• Monthly household maintenance (rent, utilities, furniture): up to €1,000/month deductible
• Travel between households: unlimited mileage or transport cost deductions
• Applies when you work in one city but family lives in another (5+ years typical requirement)
• Requires registration of the second household with local authorities

Documentation Requirements

To substantiate travel deductions:

• Mileage log: Dates, distance, business purpose, client/destination
• Travel itinerary: Departure and return dates, locations, business reason
• Receipts: Hotel invoices, train/flight tickets, rental car contracts
• Employer confirmation: If claiming tax-free reimbursements, keep approval documentation
• Electronic records: Use expense management apps (Circula, Moss) to automate capture

Common Mistakes and Audit Risks

• Claiming per diem for non-business travel (personal vacation should not be mixed with work trips)
• Forgetting the 3-month rule and claiming per diem for a long-term assignment after month 3
• Double-counting: claiming both per diem AND actual meal receipt expenses on same day
• Mixing private commute deductions with business travel per diem
• No documentation of business purpose (auditor will reject if no trip record exists)
• Inflated mileage claims without GPS logs (especially risky for frequent travelers)
• Claiming international per diem rates for domestic travel

Step-by-Step Calculation Example

You're a consultant on a 5-day client project in Munich (200 km from your home office).

• Mileage: 200 km each way = 400 km total. (20 km × €0.30) + (380 km × €0.38) = €6 + €144.40 = €150.40
• Per Diem: Monday €14 (arrival) + Tue-Thu €28×3 = €14 + €84 = €98
• Hotel: 4 nights × €120/night = €480 (receipt required)
• Parking at airport: €40 (receipt required)
• Total deductions: €150.40 + €98 + €480 + €40 = €768.40

Key Takeaways

• Verpflegungsmehraufwand: €14/day (8-24h) or €28/day (24h+) — no receipts needed.
• 3-month rule: After 3 months at same location, per diem expires; switch to actual costs.
• Mileage allowance: €0.30/km for first 20km, €0.38/km thereafter — one-way distance only.
• Overnight costs: Actual hotels for domestic, BMF rates for international travel.
• Employer reimbursement: Tax-free if within per diem and actual cost limits.
• Documentation: Keep travel itinerary, receipts, and mileage log. Expense management software simplifies this.
• Self-employed advantage: Full Vorsteuerabzug (VAT recovery) on all travel expenses reduces net cost.
