Iceland’s new kilometer road tax takes effect on January 1, 2026, fundamentally changing how drivers pay for road usage. Whether you’re planning a self-drive adventure or renting a car for the first time, understanding this new system will help you budget accurately for your Iceland trip.
What Is Iceland’s New Kilometer Tax Law?
The kilometer charge (known as “kílómetragjald” in Icelandic) is a usage-based road tax that applies to all vehicles driving on Icelandic roads. Unlike the previous fuel tax system, this new approach charges drivers based on actual kilometers traveled rather than fuel consumption.
Starting January 1, 2026, the system becomes mandatory for all vehicles, including rental cars used by tourists. The change represents Iceland’s most significant shift in road funding policy in decades, designed to create a sustainable revenue stream for maintaining the country’s extensive road network.
The base rate for standard passenger cars and SUVs (up to 3.5 tons) sits at 6.95 ISK per kilometer. Heavier vehicles pay progressively more under a 29-category weight-based scale, with the heaviest vehicles paying up to 45.17 ISK per kilometer. Motorcycles receive a 40% discount at 4.15 ISK per kilometer.
Why Did Iceland Introduce the Kilometer Tax?
Revenue Decline in the Old System
Iceland’s fuel tax revenue has dropped dramatically over the past two decades. According to official data, revenue per kilometer driven fell by 43% between 2006 and recent years. The rise of electric vehicles, plug-in hybrids, and increasingly fuel-efficient cars meant fewer liters purchased per kilometer traveled.
This created a growing gap between road maintenance needs and available funding. Iceland’s unique landscape requires significant infrastructure investment, from coastal roads exposed to harsh weather to mountain passes requiring regular maintenance.
Future-Proofing Road Infrastructure Funding
The kilometer tax provides predictable, stable revenue regardless of how vehicles are powered. Whether a car runs on electricity, hydrogen, petrol, or diesel, it pays the same rate per kilometer based on its weight category.
This approach allows Iceland to continue investing in road safety and infrastructure improvements without worrying about declining fuel sales. The government projects this system will remain viable for decades, even as the vehicle fleet transitions entirely to electric power.
Creating a Fairer System
Under the old fuel tax system, electric vehicle owners contributed nothing to road maintenance through fuel taxes, despite using the same roads as petrol and diesel drivers. Drivers of older, less efficient vehicles paid disproportionately more per kilometer than those with modern, fuel-efficient cars.
The new system charges everyone equally based on actual road usage and vehicle weight. This creates equity across all vehicle types and ensures everyone contributes fairly to infrastructure they use.
How the Kilometer Tax Works in Practice
The Rate Structure
The system uses 29 weight categories to determine charges. For most tourists renting standard vehicles:
- Passenger cars and SUVs (up to 3.5 tons): 6.95 ISK per kilometer
- Motorcycles: 4.15 ISK per kilometer (40% reduction)
- Heavy vehicles: Progressive rates up to 45.17 ISK per kilometer
Trailers weighing 10 tons or more follow a phased introduction: 60% charge in 2026, 80% in 2027, and full rate from 2028 onward.
Monthly Billing and Odometer Readings
For Icelandic residents, the system works similarly to utility billing. Vehicle owners submit odometer readings through:
- The Ísland.is portal or app
- The N1 app
- Certified inspection stations
- Regular vehicle inspections
Based on these readings, the system calculates average monthly driving and issues bills accordingly. Light vehicles (under 10 tons) require readings at least annually, while heavy vehicles need readings every six months.
Payment Terms and Due Dates
Monthly bills are issued with payment due on the first business day of each month. A 14-day grace period applies before penalties. Non-compliance can result in fines, failed vehicle inspections, and in serious cases, license plate seizure.
The Kilometer Tax and Rental Vehicles: Everything You Need to Know
Who Pays the Tax?
Car rental companies bear responsibility for paying the kilometer tax to the government. However, they pass this cost to renters through one of two methods.
All rental companies operating in Iceland must collect this government-mandated tax. The charge is separate from insurance, fuel costs, and other rental fees.
Two Payment Methods for Rental Companies
Option 1: Per-Kilometer Charging
Some rental companies calculate the exact charge based on odometer readings at pickup and return. You pay for precisely the kilometers you drove at 6.95 ISK per kilometer.
This method provides accuracy but means your final bill depends on your actual driving. A Ring Road trip covering 1,500 kilometers would cost approximately 10,425 ISK (around €70 / $75) in road tax alone.
Option 2: Fixed Daily Rate
Many rental companies simplify billing by converting the kilometer charge to a fixed daily rate. Current market rates sit around 1,390 ISK per day (approximately €9 / $10).
This approach eliminates surprise charges and makes budget planning straightforward. Whether you drive 50 or 500 kilometers in a day, the rate stays constant.
What’s Included in Your Rental Agreement
When booking, check how your chosen rental company handles the road tax:
- Is it included in the quoted price or added separately?
- Do they use per-kilometer or fixed daily rates?
- When is payment collected (at pickup or return)?
Reputable companies clearly display road tax handling during the booking process. If unclear, contact the company directly before confirming your reservation.
Odometer Requirements for Rentals
Rental vehicles require odometer readings at least every six months. The rental company handles all readings and government reporting. As a tourist, you simply pay the charge and don’t need to log anything yourself.
Cost Impact: Will It Affect My Iceland Trip Budget?
Comparison to the Old System
For the average petrol car, the new system aims for cost parity with the old fuel tax approach. The government designed the 6.95 ISK per kilometer rate specifically to match what drivers paid through fuel taxes in 2025.
Fuel prices will drop significantly as fuel taxes are eliminated. Petrol prices should fall 95-105 ISK per liter, while diesel drops 80-88 ISK per liter. A higher carbon tax partially offsets these reductions.
Estimated Costs for Common Road Trips
Here’s what to expect for popular Iceland routes:
| Route | Distance | Estimated Road Tax |
|---|---|---|
| Golden Circle | 230 km | 1,600 ISK (€11) |
| South Coast to Jökulsárlón | 700 km round trip | 4,865 ISK (€32) |
| Snæfellsnes Peninsula | 400 km round trip | 2,780 ISK (€18) |
| Ring Road complete | 1,500 km | 10,425 ISK (€70) |
| Reykjanes Peninsula | 150 km | 1,040 ISK (€7) |
For a typical week-long road trip covering 1,000 kilometers, expect approximately 6,950 ISK (€47 / $50) in road tax with per-kilometer billing, or around 9,730 ISK (€65 / $70) with daily rate billing at 1,390 ISK per day.
Who Benefits and Who Pays More?
According to the Icelandic Transport Authority, most motorists see running costs rise by 7-20%. However, the impact varies:
- Large SUV owners: May pay less overall due to fuel savings
- Small, fuel-efficient car drivers: May face slightly higher annual costs
- Electric vehicle drivers: Now contribute to road maintenance (previously exempt)
- Rural Icelandic residents: Benefit from distance-based rather than fuel-based charging
For tourists on short trips, the practical difference is minimal, especially when using rental cars with fixed daily rates.
Special Situations and Important Exemptions
Electric Vehicles and Hybrids
Electric and hydrogen vehicles pay the same kilometer rate as petrol and diesel cars in their weight category. This represents a change from the previous system where EVs were exempt from fuel taxes.
However, EVs remain exempt from Iceland’s carbon tax, providing some ongoing cost advantage. Long-term, operating an EV in Iceland remains cheaper than combustion vehicles when considering total costs.
Note that electric vehicles have been subject to a kilometer fee since 2024 (6 ISK per km), and plug-in hybrids at 2 ISK per km. The 2026 system unifies all vehicles under the same rate structure.
Tourists with Personal Vehicles
Visitors bringing their own vehicles to Iceland (typically via ferry) will pay a fixed road usage fee for their stay duration. This simplifies the process without requiring odometer logging during short visits.
You may be able to claim deductions for time spent driving abroad if you use Iceland as a transit point. Documentation of border crossings and departure dates may be required.
What’s Exempt from the Kilometer Tax
The following are exempt from the kilometer charge:
- Trailers under 3.5 tons
- Deregistered vehicles with surrendered license plates
- Agricultural and construction equipment (off-road use)
- Temporarily exported vehicles (with proper logging)
Practical Tips for Planning Your 2026 Iceland Road Trip
When Booking a Rental Car
Ask these questions before confirming:
- How is the road tax applied (per-km or daily rate)?
- Is the tax included in the online quote?
- When is payment collected?
- What happens if you drive significantly more or less than estimated?
Compare total costs including road tax across different companies. A cheaper base rate with per-kilometer charging might cost more than a higher base rate with daily charging if you plan extensive driving.
During Your Trip
For tourists renting vehicles, the process remains simple:
- The rental company handles all odometer readings and government payments
- You pay either upfront (daily rate) or at return (per-kilometer)
- No paperwork or reporting required from you
Keep your rental agreement handy in case of disputes about charges. Note your odometer reading at pickup if using per-kilometer billing.
Planning Your Route
Consider how daily distances affect your costs if paying per kilometer:
- Concentrate driving days rather than spreading kilometers across the whole trip
- Our private day tours include all road costs, eliminating uncertainty
- Popular routes like the Golden Circle remain economical even with the new tax
Addressing Common Questions
Can I avoid the tax? No. All vehicles driving on Icelandic roads must pay, regardless of ownership, fuel type, or registration country.
Will rental prices increase? The road tax is typically added separately rather than rolled into base rental rates. Total trip cost should remain similar to 2025 levels when accounting for lower fuel prices.
Is it really the same cost as before? For average petrol cars, yes. The system was designed for cost parity. Individual experiences vary based on vehicle efficiency and driving patterns.
What if I drive less than expected? With per-kilometer billing, you pay only for actual usage. With daily rates, you pay the fixed amount regardless of distance.
What about camper van rentals? The kilometer tax applies to all vehicles, including campers and motorhomes. Weight category determines the rate, so larger motorhomes may pay more than standard cars.
Do I need to do anything special as a tourist? No. Rental companies handle everything. Just understand how charges are calculated when booking and budget accordingly.
Conclusion: Planning Ahead for a Smooth 2026 Trip
Iceland’s new kilometer road tax represents a fair, sustainable approach to road funding that treats all vehicles equally. For tourists, the practical impact is modest, especially when booking with transparent rental companies that clearly explain their charging method.
The key is understanding the system before you book. Know whether your rental uses per-kilometer or daily billing, factor the cost into your budget, and enjoy your Iceland adventure without surprise fees.
