Calculate road tax for your car
MRB depends on weight, fuel, province and rules that can change. Start with technical facts on the plate — confirm officially with the Tax Office.
Which data drive MRB?
Dutch road tax (MRB) uses among other things empty mass, fuel type, and where you live (provincial surcharges). For some vehicles CO₂ or EV rates apply. RDW Open Data supplies the vehicle side; your residence and current tariff tables set the quarterly amount.
Auto Consul helps by surfacing relevant RDW traits after a plate check. We do not claim cent-exact tax math for every exception (classic rules, special vehicles, lease setups). For a binding amount: the Tax Office MRB tool.
Why this matters on a used buy
Two equally priced used cars can differ sharply in fixed monthly costs. Heavy petrol vs light hybrid, diesel rules, or an EV under temporary incentives — you feel it in the budget. Include MRB beside insurance, fuel/charging and possible parking permits.
- Plate → verify mass & fuel
- Include province in the final calculation
- EV/hybrid: verify current tariff rules
Step plan
1) Enter the plate at Auto Consul. 2) Note weight, fuel and other MRB-relevant facts. 3) Enter them in the official Tax Office calculator with your province. 4) Place that beside day value and used-car risks (APK, NAP, recalls) so you see total cost, not only purchase price.
More answers on tax and RDW limits are in the FAQ. For price context: day-value guide. For reliability: used-car check. The fastest start remains the plate.
MRB in your monthly budget beside other costs
Road tax is more predictable than fuel prices, but still a fixed cost buyers underestimate — especially on heavy petrol or diesel. Place MRB beside insurance, maintenance reserve, tyres and any lease/parking costs. A used car €1,500 cheaper to buy can cost more per year if MRB is much higher.
Electric cars have their own tariff paths that politics can change; do not assume eternal discounts. Non-plugin hybrids often tax like petrol. PHEVs only help if you actually charge. The plate check shows the technical class; the Tax Office calculates the amount.
A workflow that works: open dossier → note mass/fuel → fill the official MRB tool with your province → place beside day value and risks → only then offer. That makes ‘calculate road tax’ not a lone sum, but part of the same used-car discipline as APK and odometer checks. More questions? See the FAQ or start with a plate.
Common MRB misconceptions
Myth one: ‘the seller pays road tax until transfer, so I need not look.’ You pay from the moment the plate is in your name; the rate belongs in your purchase decision. Myth two: ‘electric is always free.’ Rules change; check current tariffs. Myth three: ‘the plate states the exact amount.’ The plate gives inputs; your province and current tables give the amount.
Myth four: ignoring MRB because you will ‘only keep the used car a year’. One year is still four quarters. Add it in financing or private-lease comparisons. A fair cost comparison between two cars without MRB is incomplete — just like without insurance.
Use Auto Consul to clean up the vehicle side, confirm at the Tax Office, and place it beside day value and dossier risks. Then calculating road tax is no longer a lone Google search, but part of the same purchase discipline as the rest of our guides.
In short
Calculating road tax starts with the plate: mass, fuel and related RDW facts. Finish with the official Tax Office tool and your province. Place MRB beside day value, insurance and used-car risks. Auto Consul delivers vehicle inputs quickly so you do not discover fixed costs only after purchase.
Extra fixed-cost checklist
For each candidate car, write the estimated quarterly MRB, indicative day value and APK horizon. Add a buffer for tyres and a service. Calculating road tax beside the RDW dossier that way stops the lowest asking price from becoming the most expensive choice over twelve months.
