Vehicle tax (Kfz-Steuer)

Vehicle tax is administered by customs, collected only by direct debit, and calculated from engine size and CO₂ emissions. The official calculator gives you the exact figure before you buy.

Quick answer

Kfz-Steuer is calculated from engine capacity plus a surcharge based on CO₂ emissions above a threshold. Diesel vehicles pay a higher rate per 100 cm³ than petrol ones, which is why a diesel is only cheaper overall at high mileage. It is administered by customs, billed annually in advance, and collected exclusively by SEPA direct debit. Electric vehicles are exempt for a period from first registration.

Important

Rates and exemptions are set by federal law and change. Use the official calculator for your specific vehicle rather than relying on an estimate, and note that the assessment is based on the data in your registration document.

1. How the tax is calculated

The tax has two components added together. The first is based on engine capacity, charged per 100 cm³ or part thereof, at a higher rate for diesel than for petrol. The second is a CO₂ surcharge applied to emissions above a threshold, on a rising scale so that higher-emitting vehicles pay disproportionately more.

The diesel differential is the part that catches buyers. A diesel costs more in tax every year, and its advantage lies in fuel consumption, so it only comes out ahead above a certain annual mileage. For a low-mileage driver a diesel is usually the more expensive choice overall.

  • A per-100 cm³ charge on engine capacity, higher for diesel than petrol
  • A CO₂ surcharge on emissions above a threshold, on a rising scale
  • Motorcycles are taxed on capacity alone
  • Electric vehicles are exempt for a period from first registration
  • Vehicles for people with certain disabilities can be exempt or reduced
  • Historic vehicles with an H registration pay a flat rate

Check the tax before you buy

The figures you need are in the Fahrzeugschein: engine capacity, fuel type and CO₂ emissions. Running them through the official calculator takes a minute and occasionally changes which car you buy.

2. How it is paid

Vehicle tax is administered by customs rather than by the tax office, which surprises people. Registration data flows automatically from the registration office to customs, and you receive an assessment without applying for anything.

Collection is by SEPA direct debit only. There is genuinely no option to pay by transfer or card, which is why a signed mandate is one of the documents you must bring to register a vehicle.

It is billed annually in advance from the date of registration, so the tax year runs from your registration anniversary rather than from January.

The German words you will see

Kfz-Steuer
Motor vehicle tax, administered by German customs.
Hubraum
Engine capacity in cubic centimetres. One of the two bases for the tax.
SEPA-Mandat
The direct debit mandate. Required at registration, because the tax is collected no other way.
H-Kennzeichen
The historic vehicle registration, for vehicles over 30 years old in original condition. Attracts a flat-rate tax.

3. Changes, refunds and non-payment

The tax liability follows the registration. Deregister the vehicle and the liability stops from that date, with the unused portion of the prepaid year refunded automatically.

That is why deregistering promptly when you sell or scrap a car matters financially as well as administratively: while the vehicle remains registered to you, the tax keeps running whether or not you have the car.

Non-payment has an unusually direct consequence. Customs can ask the registration office to force the vehicle off the road, and the office will deregister it, which is a considerably faster escalation than most tax debts produce.

  • Deregistration stops the liability from that date, with an automatic pro-rata refund
  • A change of keeper transfers the liability to the new keeper from the transfer date
  • Moving house: notify the registration office, and the tax record follows
  • Changing your bank account: notify customs, as a failed direct debit escalates quickly
  • Persistent non-payment can result in the vehicle being forcibly deregistered

4. Vehicle tax in context

Vehicle tax is usually one of the smaller items in the annual cost of running a car in Germany, and focusing on it alone leads to poor decisions. Insurance, fuel, the biennial inspection and depreciation all typically cost more.

The useful way to use the tax figure is as one input into a total annual cost comparison between two specific vehicles, alongside the insurance classification and realistic fuel consumption.

  • Insurance, which varies by model classification and your no-claims class
  • Fuel, the largest variable and the one most sensitive to your mileage
  • Vehicle tax, annually in advance
  • The HU inspection every two years, plus any work needed to pass
  • Servicing and wear items: tyres, brakes, oil
  • Depreciation, which for a newer car is the largest cost of all
  • Parking, which in city centres can exceed all of the above

Good to know

Before choosing between two cars, price the insurance for both with your own details and run both through the official tax calculator. The cheaper car to buy is frequently not the cheaper car to own.

5. Frequently asked questions

Two components added together: a charge per 100 cm³ of engine capacity, at a higher rate for diesel than petrol, plus a CO₂ surcharge on emissions above a threshold on a rising scale. The official calculator gives the exact figure for your vehicle.

The per-100 cm³ rate is higher for diesel. Diesel’s advantage is in fuel consumption, so it only works out cheaper overall above a certain annual mileage. For a low-mileage driver a diesel is usually more expensive to own.

By SEPA direct debit only. There is no option to pay by transfer or card, which is why a signed mandate is required when you register the vehicle. Customs administers the tax, not the tax office.

Electric vehicles are exempt from vehicle tax for a period from first registration. Because the length of that period has been legislated and extended more than once, check the current rule with customs for a specific vehicle.

Liability follows the registration. On a transfer of keeper or deregistration, your liability stops from that date and the unused portion of the prepaid year is refunded automatically. Until then the tax keeps running against you.

Customs can require the registration office to take the vehicle off the road, and it will be deregistered. This escalates faster than most tax debts, so a failed direct debit is worth resolving immediately.

Yes, and you should. Take the engine capacity, fuel type and CO₂ figure from the Fahrzeugschein and run them through the official calculator. It takes a minute and occasionally changes the decision.
