Key takeaways
- 01Engangsavgift is Norway's one-off registration tax paid when a passenger car is first registered in the country.
- 02The 2026 calculation uses kerb weight and CO2 emissions as the primary inputs; NOx was removed from the tax from 1 January 2026.
- 03Electric cars are generally outside the combustion CO2 component but may still be affected by the weight charge.
- 04This tool gives a planning estimate — use Skatteetaten for the official assessment.
What Is Norwegian Engangsavgift and Why Does It Matter?
Engangsavgift is the one-off registration tax levied when a passenger car is first registered in Norway. Unlike an annual road tax, it is charged once — but the amount can be substantial, making it one of the most significant costs when importing or buying a new car in Norway.
The tax is structured around environmental and weight factors. Under the 2026 rate structure, the key components are a weight charge based on kerb mass above 500 kg and a CO2 component for combustion vehicles that rises through progressive rate bands. From 1 January 2026, the NOx element was abolished entirely, simplifying the calculation. Understanding these components before purchase lets you compare vehicles and plan your budget without surprises at the Skatteetaten counter.
How to Use the Norway Engangsavgift Calculator
The tool runs entirely in your browser — no data is uploaded, no account needed.
- 01
Enter kerb weight
Type in the vehicle's kerb weight in kilograms. You'll find this on the EU type-approval document or the manufacturer's spec sheet. The weight component kicks in above 500 kg.
- 02
Enter CO2 emissions
Input the official WLTP (or NEDC if the vehicle predates WLTP) CO2 figure in g/km. This drives the CO2 rate-band calculation for combustion vehicles.
- 03
Select fuel type
Choose petrol, diesel, hybrid, or electric. Fuel type determines which rate tables apply and whether the combustion weight surcharge is included.
- 04
Review the breakdown
The calculator displays a line-by-line breakdown: weight component, CO2 component (NOx shown as zero from 2026), and the estimated total engangsavgift.
- 05
Cross-check with Skatteetaten
Take the estimate to Skatteetaten's official calculator or an approved importer to confirm the final assessment, which may account for additional vehicle-group rules and exemptions.
Information to Gather Before You Calculate
Have these details ready from the vehicle's registration certificate or type-approval documents:
- 01Kerb weight in kilograms (not gross vehicle weight)
- 02Official CO2 emissions in g/km (WLTP preferred for post-2018 vehicles)
- 03Fuel type (petrol, diesel, plug-in hybrid, or full electric)
- 04Vehicle category (passenger car — the calculator is designed for M1 class)
- 05First registration date if estimating for a used import
Privacy and Accuracy Notes
All calculations happen inside your browser. No vehicle data, prices, or personal information is sent to any server. You can use the tool on a mobile connection or offline after the page loads.
The rates reflect the 2026 public rate structure from the Norwegian budget proposal and Skatteetaten source links. Because engangsavgift can vary based on vehicle-group classification, approval status, and exemptions not captured in a simple estimator, treat the result as a planning guide rather than a billing notice. For the final payable amount, always consult Skatteetaten or a licensed Norwegian importer.
Norway Engangsavgift FAQ
What is engangsavgift in Norway?
It is the one-off registration tax paid when a vehicle is first registered in Norway. It is separate from the annual road tax (årsavgift) and is paid only once.
What inputs affect Norwegian car import tax?
For passenger cars, kerb weight and CO2 emissions are the main drivers. Vehicle group, type-approval data, and any applicable exemptions can also affect the official result.
Do electric cars pay engangsavgift?
Pure electric cars are generally outside the combustion CO2 component but can be affected by the passenger-car weight charge and Norwegian VAT rules. Check the latest Skatteetaten guidance for EVs.
Was NOx removed from engangsavgift?
Yes. The Norwegian Tax Administration confirmed that the NOx element was abolished from 1 January 2026, so it is no longer a factor in the one-off registration tax.
Is this the official Skatteetaten calculator?
No. This is an independent browser-only planning estimate. Use Skatteetaten's own tool or an authorised importer for the legally binding figure.
Can I use this calculator for used imports from Germany or Japan?
Yes, as long as you enter the vehicle's kerb weight and CO2 figure from its official documents. Engangsavgift applies on first Norwegian registration regardless of where the car was originally sold.
