Revenue's own arithmetic on your figures, one question at a time — and, when you have no OMSP yet, the Irish market's own asking-price median beside it.
Category A (M1 passenger car) only. Nothing you type here is stored or sent anywhere: the calculation runs in your browser.
Every other VRT calculator runs the same public formula over an Open Market Selling Price you have to find somewhere else. This one does that, and it also holds a series of Irish asking prices from DoneDeal, so it can stand something real beside the formula when you have nothing to put into it. Every rate here says where it came from and when we read it, which is what you need if you ever want to query a charge.
The VRT arithmetic here is Revenue's, out of its Tax and Duty Manual on the valuation of used vehicles: the 20 CO2 bands and their minimum amounts, the NOx levy and its two caps, the 24 depreciation tables, the extras ladder, the supplementary monthly adjustment, the condition scale and the excess-kilometre scales. Given the same inputs it reproduces Revenue's own three worked examples to the euro.
What it cannot do is decide the OMSP. That is Revenue's own valuation of what the car would fetch in Ireland, and it is made at the National Car Testing Service when the car is presented.
It is Category A only — an M1 passenger car. There is no Category B or N1 arithmetic here, no Returned Goods Relief and no disabled drivers' scheme. The battery electric relief is applied, because leaving it out overstates VRT on an electric import by up to €5,000.
Two dates worth knowing whatever the figure says: an NCTS appointment must be booked within 7 days of the vehicle entering the State, and the registration completed within 30 days.
The steps around the arithmetic are written up separately: importing a car from the UK covers the Northern Ireland proofs, the Great Britain customs declaration, the checks and the documents the NCTS asks for. Importing a car from Japan covers the exporter sites, what an FOB price leaves out, auction grades, shipping and the statement on origin that turns the 10% duty into 0%.
Estimate mode substitutes the median asking price of DoneDeal listings for that make, model and year. Those are asking prices, not sale prices, and they are not the same thing as an OMSP — Revenue arrives at its figure a different way. They are, though, the only Irish number available before the car reaches the NCTS, and nobody else publishes them. The same series is behind the depreciation tracker, and what it shows about how fast Irish cars lose value is written up in the depreciation guide.
The variant list is the UK Vehicle Certification Agency's Car Fuel Data, the published type-approval figures for cars on sale in the UK, held here one edition at a time and never fetched while you are on the page. Column "Emissions NOx [mg/km]" is already in the unit Revenue charges on, so nothing is converted between the published file and the box above. A diesel importer who cannot evidence NOx pays Revenue's flat maximum of €4,850; on the median diesel in that dataset the real figure costs about €120, which is why this lookup exists.
