Calculate DANISH vehicle registration tax (registreringsafgift) for a new or used personbil, varebil or motorcykel under registreringsafgiftsloven. Same engine and validation as bildata.io's public calculator. Amounts in DKK; an estimate, not an official Motorstyrelsen valuation. REQUIRED PAIRS: condition="new" needs bruttovaerdi; condition="used" needs handelspris AND nypris (nypris is the used vehicle's own original price when new, not the new-vehicle price field). ALWAYS send co2 for a petrol, diesel or hybrid PERSONBIL or VAREBIL: an omitted co2 counts as 0 g/km, i.e. battery-electric, and makes the tax far too low with no error raised — zero on an ordinary car, and still only a fraction of the real figure on an expensive one. On motorcykel co2 does not select the drivetrain at all - isElectric does. Send every number as a JSON number (300000, not "300000"), use enum values exactly as listed, and OMIT an optional field you do not know rather than sending null.
new = first registration of a new vehicle; used = import/revaluation of a used vehicle
Vehicle category under Danish law
WLTP CO2 in g/km. PERSONBIL and VAREBIL: send it for any fuel-burning vehicle - an omitted value and an explicit 0 are BOTH read as battery-electric (EV phase-in and EV bundfradrag), which makes the tax far too low. Use 0 only for a pure EV. MOTORCYKEL: co2 does not select the drivetrain here; isElectric does, and a motorcykel sent with co2=0 and no isElectric is priced as fuel-burning.
Varebil only: open cargo bed (ladvogn)
Used: average odometer km of the comparable adverts. Part of the actualKm/avgKm/vehicleAgeYears set — a partial send is silently ignored.
Used vehicles: REQUIRED when condition="used". The SAME vehicle's original price as new in DKK, incl. all taxes. Unused when condition="new" — for a new vehicle use bruttovaerdi.
Used: actual odometer km. The km regulation is skipped entirely unless actualKm, avgKm, vehicleAgeYears AND handelspris are all present.
Electric consumption in Wh/km. Send WITH elRaekkevidde — the battery deduction is (elForbrug/1000) * elRaekkevidde, so either one alone is a no-op.
MOTORCYKEL: the EV switch for that vehicle type. For personbil and varebil the drivetrain comes from co2 (0 or absent = electric), so this flag does not change the tax — but DO send it for a battery-electric personbil or varebil: it is read as your declaration that the missing co2 is deliberate, and suppresses the warning that the answer looks too low.
Rules year to calculate under (default: current). A year with no published table silently falls back to the current rates; the answer's rules_year says which table actually applied.
Varebil only: total weight in kg
Used vehicles: REQUIRED when condition="used". Current Danish trade price in DKK, incl. registration tax. Unused when condition="new".
New vehicles: REQUIRED when condition="new" (unused when condition="used"). Taxable value in DKK, i.e. price incl. VAT and margin BEFORE registration tax. NOT the advertised Danish showroom price, which already contains the tax being calculated.
Electric range in km (WLTP). Send WITH elForbrug — either one alone is a no-op.
Used: maintenance condition (vedligeholdelsesstand)
Used: vehicle age in years since first registration. Also used on its own for the under-6-months rule, so send it even when you cannot supply the km set. The km regulation additionally needs actualKm, avgKm and handelspris — that part is skipped unless all are present.
Used: true only if EVERY comparable advert is a dealer listing (enables annoncefradrag + leveringsomkostninger)

}Project DANISH registration tax for a NEW vehicle across rules-years 2026–2029 (the EV/plug-in phase-in schedule changes the tax each year). Returns per-year results and deltas vs 2026. Amounts in DKK. Estimates, not official valuations. NEW vehicles only, and always the whole 2026-2029 span: for a USED import, or for a single year, use calculate_registreringsafgift instead. Send every number as a JSON number (300000, not "300000").

}Danish new-vehicle registration statistics from bildata.io (weekly DMR data). Dimensions: fuel_type, brands (top 20), evs, imports (vehicles brought in from abroad, by toldsyn date: counts, share, top makes), monthly_totals (last 12 months incl. leasing series), country_of_origin. kind=all covers every vehicle type; kind=Personbil passenger cars only. as_of is the data cutoff of the underlying extract — a month whose as_of is before month-end is PARTIAL. Market-level ONLY: the brands dimension is the top 20 brands and there is no per-model breakdown here — for a named MODEL use get_model_stats. It is NOT a way to get a brand total for a brand outside the top 20: a brand-only query there returns that brand's individual model rows (default 5, max 10, truncation disclosed in `note`) and defaults to kind=Personbil where this tool defaults to kind=all, so summing them does not reproduce a brand total from here.

}Look up Danish registration numbers for a SPECIFIC car model by name — e.g. "Tesla Model Y", "VW ID.4", "Skoda Enyaq". Covers every model since 2018. Use this when the question names a model or brand; get_top_models only covers the top sellers of one month, and get_market_stats only the top 20 brands. A model still selling returns period figures (this month, this year, last year, market share) plus all-time totals. A model with no registration in the last ~3 years returns ONLY lifetime totals and its first/last registration date — the period figures do not exist for it and are listed in `unavailableFields`; their absence is missing data, NOT zero sales. Spelling is forgiving (ID.4 = ID 4 = id4, Citroen = Citroën) and the response states which row it matched and how, so verify `name` before quoting the numbers.
| Argument | Type | Description |
|---|---|---|
| kind | string | Default: Personbil (passenger cars) |
| limit | integer | Max matches to return, default 5 |
| query* | string | Model or brand name, e.g. "Tesla Model Y" or "Toyota" |

}Top-selling car models (and variants) in Denmark for a given month, from bildata.io's top-50 statistics (passenger cars, monthly, 12-month rolling window). Default: latest month, top 10. as_of is the data cutoff — if it is before month-end, the month is PARTIAL, not complete. A RANKING, bounded by the 12-month window. A model outside that month's top 50 is absent here — look that one up by name with get_model_stats. A month OLDER than the window cannot be answered by any tool on this server: get_model_stats reports fixed periods relative to today (this month, this year, last year, all-time), never an arbitrary past month.
