What is a car vrt calculator?
A car VRT calculator is an online tool designed to estimate the Vehicle Registration Tax (VRT) payable on vehicles being imported into Ireland. This tax is a mandatory one-off levy administered by the Irish Revenue Commissioners upon the first registration of a motor vehicle in the state. The calculation is complex, depending on several factors including the vehicle’s Open Market Selling Price (OMSP), its carbon dioxide (CO₂) emissions, and in many cases, its Nitrogen Oxide (NOx) emissions. Our calculator simplifies this process, providing a reliable estimate for private buyers and motor traders planning an importation.
The car vrt calculator Formula and Explanation
There isn’t a single formula for VRT, but rather a multi-step calculation based on emission levels and vehicle value. The total VRT is the sum of a CO₂-based charge and a NOx levy.
Total VRT = (CO₂ VRT Charge) + (NOx Levy) – (Reliefs)
- CO₂ VRT Charge: This is calculated as a percentage of the vehicle’s Open Market Selling Price (OMSP). The percentage rate is determined by which band the vehicle’s CO₂ g/km emissions fall into. Rates can range from 7% for the cleanest vehicles to 41% for those with high emissions.
- NOx Levy: This is an additional charge for diesel and some petrol vehicles based on their NOx mg/km output. The charge is applied per milligram, but it is capped at €4,850 for diesel and €600 for other fuel types.
- Reliefs: Electric vehicles (EVs) and some hybrids may be eligible for VRT reliefs, which are subtracted from the total.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| OMSP | Open Market Selling Price | Euros (€) | €2,000 – €150,000+ |
| CO₂ Emissions | Carbon Dioxide output | g/km | 0 – 300+ |
| NOx Emissions | Nitrogen Oxides output | mg/km | 0 – 100+ |
Practical Examples
Understanding how inputs affect the final tax is crucial. Here are two realistic scenarios:
Example 1: A Modern Family Diesel Car
- Inputs: OMSP: €28,000, CO₂: 125 g/km, NOx: 40 mg/km (Diesel)
- CO₂ Charge: A 125 g/km emission level falls into a 16.75% band, resulting in a charge of €4,690.
- NOx Levy: At €15 per mg/km (for 31-40mg range), 40mg * €15 = €600.
- Total VRT (Result): €4,690 + €600 = €5,290
Example 2: A Small Petrol City Car
- Inputs: OMSP: €19,500, CO₂: 105 g/km, NOx: 20 mg/km (Petrol)
- CO₂ Charge: A 105 g/km emission level falls into a 12.75% band, resulting in a charge of €2,486.25.
- NOx Levy: At €5 per mg/km (for 0-60mg range), 20mg * €5 = €100.
- Total VRT (Result): €2,486.25 + €100 = €2,586.25
How to Use This car vrt calculator
Using our calculator is straightforward. Follow these steps for an accurate estimation:
- Enter the OMSP: Input the Open Market Selling Price in Euros. This is not what you paid, but what Revenue deems it’s worth in Ireland. You can find this on Revenue’s website or use our VRT Check tool.
- Input CO₂ Emissions: Enter the grams per kilometer (g/km) value from the vehicle’s V5C logbook or Certificate of Conformity.
- Input NOx Emissions: Enter the milligrams per kilometer (mg/km) for NOx. This is especially important for diesel vehicles. You can use a NOx estimator if unsure.
- Select Fuel Type: Choose the correct fuel type as this affects NOx caps and reliefs.
- Calculate: Click “Calculate VRT” to see the instant results, including a breakdown of the costs. The VRT bands are automatically applied.
Key Factors That Affect car vrt calculator
- CO₂ Emissions: This is the most significant factor, determining the percentage of the OMSP you will pay. Lower is always better.
- Open Market Selling Price (OMSP): A higher value vehicle will incur a higher VRT charge, as the tax is a percentage of this price.
- NOx Emissions: For diesel and older petrol cars, this adds a significant extra levy to the total tax.
- Fuel Type: Electric vehicles receive substantial VRT relief, while diesel vehicles are subject to higher potential NOx charges.
- Vehicle Age and Depreciation: While not a direct input in this calculator, age and mileage heavily influence the OMSP determined by Revenue.
- Optional Extras: Enhancements or accessories fitted to the car can increase its OMSP, thereby increasing the VRT.

Frequently Asked Questions (FAQ)
The OMSP is Revenue’s estimate of what the car would sell for in Ireland. It is based on a database of vehicle values and is not necessarily the price you paid. You must use the OMSP lookup tool for an official valuation.
These values are critical for an accurate car vrt calculator estimate. They should be on the vehicle’s documentation (V5C or CoC). If unavailable, you may need to contact the manufacturer. Using an incorrect value can lead to a significantly different final charge.
Yes. This calculator provides an estimate only. The final VRT amount is confirmed by Revenue after a physical inspection at an NCTS centre.
The OMSP value used for the calculation is inclusive of VAT. If you are importing from outside the EU (e.g., Great Britain), you may also be liable for a separate VAT payment at the point of entry.
Yes, some reliefs may be available for plug-in hybrid vehicles, which can reduce the final VRT payable. Our calculator accounts for major reliefs, but specifics should be checked with Revenue.
You can appeal the OMSP valuation after you have paid the initial VRT charge. You must provide evidence to support your claim, such as proof of lower market values for identical vehicles in Ireland.
You must book an NCTS inspection within 7 days of the vehicle arriving in Ireland and complete the registration and pay VRT within 30 days.
No, this calculator is specifically for passenger cars (Category A). Commercial vehicles (Category B/C) have different VRT calculation methods, often a percentage of the OMSP (13.3%) or a flat fee.
