A normal US import: three taxes, not one
For a normal vehicle imported from a third country, Portuguese guidance is clear that, unless a relief applies, the vehicle is subject to three separate layers. They are not one blended “Portugal import tax” — treating them as one is how budgets go wrong.
1 · Customs duty
For an ordinary passenger car (CN heading 8703), the standard third-country MFN tariff is 10% of the customs value — but a vehicle of US customs origin currently qualifies for 0% under Regulation (EU) 2026/1455 (its Annex I covers Chapter 87, vehicles; in force 1 July 2026 to 31 December 2029). The decisive word is origin, not where you bought or shipped the car: origin is determined by EU non-preferential origin rules, so a US-market car built in Germany, Japan, Mexico or Korea is not US-origin. For such a car the standard tariff normally applies — 10% for an ordinary passenger car — unless another applicable preference or customs relief applies. Motorcycles, commercial, special-purpose and historic vehicles use different rules. Establish classification and origin for your exact vehicle before assuming either rate.
2 · Import VAT
Portuguese import VAT is 23% on the mainland (22% in Madeira, 16% in the Azores). Crucially, the VAT base is not the sticker price: it includes the customs value, the customs duty and other import charges — including the ISV. VAT is effectively charged on top of the duty and the ISV.
3 · ISV
ISV, the one-time vehicle tax, applies to imported vehicles regardless of origin. It is based on CO₂ emissions and engine size. For a US import there is one decisive difference from an EU import, covered next: no age reduction.
Used does not mean discounted ISV
Portugal’s Tabela D reduces ISV by up to 80% for older vehicles — but the Tax Authority states plainly that this reduction applies only to used vehicles bearing definitive registration plates assigned by another EU Member State. Its own guidance is explicit that used vehicles from third countries receive no reduction of the tax at all. The USA is a third country.
So the same physical car is taxed very differently depending on where it is coming from: a used car imported with a permanent German or French registration gets the age reduction; the identical car imported from the USA does not. This is the single most common miscalculation in a US import — the age of the car does you no favours on ISV. (The one thing that can remove ISV is a separate legal exemption, such as the residence-transfer exemption below, or the vehicle being fully electric — not its age.)
Why a cheap US car does not stay cheap
The reason a bargain evaporates is that the taxes stack on each other rather than sitting side by side. Reading top to bottom, each layer feeds the next:
Customs value
Broadly the transaction value, plus transport and insurance to the EU point of entry (verified under customs valuation rules).
+ Applicable customs duty
On the customs value — normally 10% for a standard passenger car, but 0% for a vehicle of US customs origin under Regulation (EU) 2026/1455. It can be zero; it is decided by customs origin, not by where the car was shipped from.
+ ISV
The one-time vehicle tax — full amount, with no age reduction for a US car.
= Import VAT base
VAT (23% mainland) is charged on a base that already includes the customs value, the duty and the ISV.
The exact figures are a per-vehicle calculation — this shows the order the charges build in, not a worked example. Shipping, insurance, port handling, brokerage and registration sit on top of all of this.
One move, three tax questions
If you are moving from the USA and already own the car (person B above), the picture changes — but not into a single “relocation exemption”. A move from outside the EU can involve three separate reliefs, each assessed on its own terms:
- Portuguese ISV residence exemption. Can remove ISV on a genuine transfer of residence. The USA being a third country does not by itself block it. Its main conditions: over 18; prior normal residence abroad of at least 6 months; the vehicle owned and used for at least 6 months before the move; request within 12 months of establishing Portuguese residence; one vehicle per beneficiary.
- EU customs-duty transfer-of-residence relief. A separate EU regime. Broadly requires normal residence outside the EU customs territory for a continuous period of at least 12 months, the vehicle possessed and used for at least 6 months, and entry for free circulation within 12 months of the move.
- Import-VAT transfer-of-residence relief. A further separate EU regime, with its own conditions broadly aligned to the customs relief.
Buying vs moving: what applies
| Buy / normal import | Move with owned car | |
|---|---|---|
| Customs duty | 10% MFN — or 0% if US-origin (Reg. 2026/1455) | Possible residence relief |
| Import VAT | Usually due | Possible relief |
| Portuguese ISV | Due unless exempt | Possible Art. 58 exemption |
| EU used-car age reduction | No | Irrelevant if ISV exempt; otherwise no |
| Homologation | Required | Required |
| Portuguese registration | Required | Required |
| Shipping / insurance / port | Required | Required |
“Possible relief” means exactly that — conditional, and assessed separately for each regime. Relocation is never simply “free”: the other process costs remain.
Before you ship: can Portugal register this exact vehicle?
This is the question the tax numbers cannot answer, and the one most likely to strand a car after it arrives. Tax looking fine does not mean Portugal can register the vehicle via the simple route. Establish the homologation path for the specific vehicle before shipping — US vehicle documents may not carry the European structure, and many US-spec vehicles may not have a European Certificate of Conformity.
- 1Does this exact vehicle have a European type approval, with a corresponding Certificate of Conformity you can present?
- 2If YES — it can generally use the normal IMT homologation-record lookup route (simpler).
- 3If NO or UNKNOWN — do not assume registration is straightforward. It likely goes through Modelo 9-IMT certified via the manufacturer's official representative in Portugal, which can be slower, costlier and, for some models, uncertain.
The technical detail behind this: a foreign registration certificate identifies the type approval in field K and the model/variant/version in field D.2. When those fields are absent or unfilled, the IMT homologation-record request can only proceed if the corresponding CoC is presented; otherwise the vehicle takes the Modelo 9 route. A European CoC can prove the type approval and supply the technical data — which is why, for a US car, whether a CoC exists often decides how hard registration will be. It is not a checker, and no CoC does not automatically make registration impossible; but for a US-spec vehicle it usually signals a more involved route. See the Certificate of Conformity guide for what a CoC does and the missing-CoC case.
Will a US-spec car need modifications?
Possibly — but this is deliberately where we do not hand you a universal checklist. A US-spec vehicle without a European type approval may need technical adaptations or additional evidence before Portuguese approval, and the exact requirements depend on the specific vehicle and the homologation route. Commercial sites often publish generic US→EU retrofit lists (lighting, indicators, glass markings, instruments, emissions equipment); we do not reproduce those as universal requirements, because they are not uniformly correct across vehicles and we cannot scope them for your exact car here.
Before the car leaves the US
US export requirements are separate from Portuguese import requirements, and they are handled on the US side first. The core rule for a used self-propelled vehicle is a filing obligation, not a “turn up early” one:
- Electronic Export Information must be filed through the Automated Export System (AES), which produces an Internal Transaction Number (ITN).
- The ITN, the Vehicle Identification Number and the vehicle’s title must be presented to the CBP port of export at least 72 hours before the vehicle is exported.
- Ownership/title evidence is central. Liened, leased or salvage/rebuilt-title vehicles are edge cases with extra requirements — check them before committing.
Port procedures vary, so confirm the exact steps with CBP and your specific port of export. This page is not a US export-compliance manual; it flags the requirement so it does not surprise you after you have paid for freight.
Electric cars from the USA
Electric removes the ISV problem — it does not automatically remove the import or the homologation problem. A 100% battery-electric car is outside ISV and exempt from annual IUC. But imported normally from the USA, an electric car can still face EU customs duty and Portuguese import VAT, and it still needs homologation and Portuguese registration like any other US vehicle. Plug-in hybrids do not get the same treatment as full electrics. See the EV import guide for the electric specifics.
Shipping: why there is no single number
We do not publish a “USA to Portugal shipping price”, because there isn’t one. The cost swings with your origin location and US port, the destination port, RoRo versus container, the vehicle’s size, inland transport, marine insurance, port handling, customs brokerage, and any storage or demurrage if clearance is slow. Timing matters too. Two identical cars can cost very different amounts to move.
Get a real quote for your route rather than a headline figure — and note that a vehicle may first be customs-cleared in another EU Member State before reaching Portugal, which can change the practical workflow. Do not assume every US car simply arrives in Lisbon.
Classics, collectors and unusual titles
Two edge cases deserve a flag rather than a full treatment here. Historic or collector vehiclescan fall under different customs classification, VAT and homologation/inspection rules and are outside this page’s standard passenger-car route — do not assume every older car qualifies as a “classic” for tax purposes; confirm the specific classification. And a US vehicle’s title history — clean, salvage, rebuilt, flood or prior total-loss — should be checked before purchase or shipping: technical and registration acceptance should not be assumed for an unusual title status. Establish document and history status privately, before you commit money.
Before you book shipping: verify these first
Should you bring it or sell it in the US?
This is a decision, not a recommendation we can make for you. The honest method is the same in both directions: calculate the tax route, confirm the homologation route, then compare the remaining Portugal cost against simply replacing the car.
For a normal import, weigh the expected customs duty, import VAT and full ISV (no age reduction), plus shipping, homologation uncertainty and registration costs, against the price of buying an equivalent car already in Portugal. For a relocation, weigh the probability of actually meeting each relief’s separate conditions against the remaining shipping, registration and homologation costs — and any sentimental or special-vehicle value. A car that makes no sense as a normal import can become rational under a valid relocation exemption; the numbers, not the wish, decide it.
What CarTaxPortugal can — and cannot — tell you
Can help with
- Portuguese ISV and IUC estimates (with the correct third-country, no-age-reduction treatment)
- Import-cost estimates via the calculator’s adjustable variables
- Document-readiness for a Portuguese import
- Explaining the official tax and homologation rules
Cannot currently confirm
- The exact customs classification or customs origin for every vehicle (which decide the duty)
- An exact freight, port or customs-brokerage cost
- Portuguese homologation acceptance for a specific US-spec VIN
- The exact technical modifications a vehicle will need
- Approval of customs/VAT or ISV residence relief
- Official vehicle-history status
The calculator gives an estimateof the Portuguese taxes it can model — never an “exact total” while customs, VAT, freight and homologation remain variable.
