Company car and home office in Germany: per-trip valuation

Why the 0.03% rule gets expensive with hybrid work

Under the 0.03% rule, the commute in a company car (Dienstwagen) is taxed as a flat rate: every calendar month, 0.03% of the list price per kilometer of distance to the first place of work (erste Tätigkeitsstätte) is added to taxable pay (§ 8(2) sentence 3 of the Income Tax Act, EStG). How often the car actually goes to the office doesn't matter. The Federal Ministry of Finance (BMF) explicitly names part-time work, home office, business trips and short-time work as reasons that don't change the flat rate (BMF guidance of March 3, 2022, para. 12).

Mathematically, the monthly flat rate assumes 15 commuting days, because 15 trips at 0.002% each add up to exactly 0.03%. Someone who only goes to the office two days a week is therefore taxed on almost twice as many trips as they make.

The flat rate for private use is not affected. It stays at 1% of the list price per month, no matter how much the car is driven privately (§ 6(1) no. 4 sentence 2 EStG, R 8.1(9) no. 1 of the wage tax guidelines, LStR). Per-trip valuation only changes the commuting part. The calculator with all reductions for electric and hybrid cars is part of the company car tax dataset.

Per-trip valuation: 0.002% per trip

Instead of the monthly flat rate, the tax authorities allow valuing the actual trips: 0.002% of the list price per kilometer of distance and trip, for no more than 180 trips per calendar year (BMF guidance of March 3, 2022, para. 13). The method goes back to three judgments of the Federal Fiscal Court (Bundesfinanzhof, BFH) of September 22, 2010 (VI R 54/09, VI R 55/09 and VI R 57/09) and is not written into the statute.

The 180-trip cap applies per year and to all cars provided to the employee combined. There is no monthly cap of 15 trips. If someone drives to the office twice on the same day, that day counts once (para. 13 a and c).

The BMF works through an example itself: 14 trips in each month from January to June, 19 trips from July to November. That makes 179 trips by the end of November, so only one trip counts in December, even though the employee drove on four days. In the months with 19 trips the value is above the flat rate, but over the whole year it equals twelve monthly flat rates.

How many office days make per-trip valuation worth it

Per-trip valuation is cheaper as long as the employee goes to the office on fewer than 15 days a month on average. At 15 days both methods are equal, and above that per-trip valuation costs more in that month. In the example, eight office days lower the value of the commute from €450.00 to €240.00, while private use stays at €500.00.

Over the year, the 180-trip cap comes into play. It limits the total of per-trip valuation to the value of twelve monthly flat rates. Someone who drives in more than 15 days in some months pays more for a while, but over a full year no more than with the flat rate. That only holds if the car is available for all twelve months: if someone gets the car during the year, fewer monthly flat rates face the full 180-trip cap.

So one estimate is enough for the decision: office days per year. With two office days a week and 46 working weeks, that's 92 trips, just over half the cap. With four days a week it's 184, and per-trip valuation brings nothing over the year except extra paperwork.

Requirements and payroll process

• Each month, employees declare in writing and per car on which dates they drove to their first place of work. Just stating the number of days is not enough (BMF guidance of March 3, 2022, para. 13 a).
• The employer keeps the statements as records in the payroll account. For withholding, it may use the previous month's statement.
• If employees ask for it, the employer has to apply per-trip valuation, unless the employment contract says otherwise (para. 13 e).
• The method is set for each calendar year, uniformly for all cars provided, and may not change during the year. Switching retroactively for the whole year is possible until the annual wage tax certificate is issued (para. 13 f).
• Payroll counts the trips across the year and stops at 180.
• If the employer applies the flat rate, employees can switch to per-trip valuation for the whole year in their tax return. They need the dated list of trips and proof that the flat rate was taxed (para. 13 g).

Electric cars: a quarter of the list price, for the commute too

For a fully electric car, only a quarter or half of the gross list price counts, depending on the purchase date and price (§ 6(1) no. 4 sentence 2 EStG). The reduction also applies to the commute, because § 8(2) sentence 3 EStG refers to the list price as defined in that provision. Rounding down to the full hundred euros happens only after the reduction.

Example: an electric car with a list price of €60,250, bought in September 2025, 30 km commute. The calculator uses €15,000.00, which gives €150.00 for private use and a flat €135.00 for the commute. With eight office days and per-trip valuation, the commute drops to €72.00.

Which price cap applies to which purchase date is listed with the calculator. Pass antrieb, anschaffung and, for hybrids, CO2 emissions or electric range, and the calculator picks the right reduction. All parameters are explained in the company car calculator reference.

Employee contributions

If the employee pays a fee for using the car outside work, it reduces the taxable benefit (geldwerter Vorteil) (R 8.1(9) no. 4 LStR). That covers a fixed monthly fee, a per-kilometer fee and lease payments the employee takes over, and under the flat-rate method also individual costs the employee pays personally, such as fuel (BMF guidance of March 3, 2022, para. 53).

A salary sacrifice arrangement doesn't count as a usage fee (para. 55). If the fee exceeds the benefit, the benefit only drops to zero, and the rest is neither negative pay nor a deductible expense (para. 56). Contributions to the purchase price can be spread over the agreed period, or, without such an agreement, also offset in later years (paras. 65 and 66).

In the electric car example, the employee pays €50 a month. The calculator deducts it via zuzahlung_monat: €150.00 for private use and €72.00 for the commute become a taxable benefit of €172.00.

What employees get back: commuting and home office allowances

For every day the employee drives to the first place of work, they can deduct the commuting allowance (Entfernungspauschale) as a work expense: €0.38 per kilometer of one-way distance, company car included (§ 9(1) sentence 3 no. 4 EStG). The annual cap of €4,500.00 doesn't apply here, because the law lifts it for a car provided to the employee.

For home office days, there is a daily allowance (Homeoffice-Pauschale) of €6.00 instead, up to €1,260.00 a year, if the employee mainly works at home that day and doesn't go to the first place of work (§ 4(5) sentence 1 no. 6c EStG). Both work through the tax return, and only to the extent that all work expenses together exceed the employee lump sum (Arbeitnehmer-Pauschbetrag) of €1,230.00.

The employer can't pay these allowances tax-free. Which amounts are the employee's own work expenses is shown in the wirkung field of the tax-free benefits dataset.

Calculating company car benefits via the API

The dienstwagen calculator returns both values in one response: fahrten_wohnung_monat for the flat rate and, if you pass fahrten_monat, fahrten_wohnung_monat_einzel for per-trip valuation. The arbeitsweg_methode field tells you which value is included in the taxable benefit. On the MCP server, the tool is called hr_dienstwagen.

The calculator doesn't check the 180-trip cap, since it only sees one month, so payroll keeps the running total for the year. What the API calculators cover and what they don't is explained under calculators and their limits.

Checklist before year end

• Estimate office days per employee for next year, plus the months with a company car.
• If the average is below 15 days a month, offer per-trip valuation and give employees the form for the monthly statement.
• Set the method for the year in the payroll system and add a counter for the 180 trips.
• Record usage fees and contributions per car so they reduce the benefit.
