Assumptions and estimates
- Category A passenger-vehicle estimate using Revenue OMSP, not the purchase price. Revenue decides the valuation, category and accepted emissions evidence.
- VAT, Customs Duty, inspection and registration fees, transport and additional VRT for late registration are excluded. Hybrids use their combustion fuel type and have no battery-only electric relief.
- CO₂-based rates are the published bands from 1 January 2022. The electric relief expiry is 31 December 2026; later rules must be rechecked.
- Method: CO₂ determines a percentage of OMSP with a minimum levy. The separate stepped NOx charge is then added after any applicable EV relief.
- OMSP is determined by Revenue, not the foreign purchase price. This excludes import VAT, customs duty, registration costs and other vehicle categories. It is an estimate, not a binding VRT assessment.

How the vrt & nox import estimate calculation works
CO₂ determines a percentage of OMSP with a minimum levy. The separate stepped NOx charge is then added after any applicable EV relief.
OMSP is determined by Revenue, not the foreign purchase price. This excludes import VAT, customs duty, registration costs and other vehicle categories. It is an estimate, not a binding VRT assessment.
Using this calculator
