IUC, INSURANCEAND IPO.
A car in storage stops moving. Its obligations do not. What Portuguese law still asks of a stored car — road tax, insurance and inspection — and what happens if they lapse.
Owners often assume that a car put away for the season is, in the eyes of the state, put away too. It is not. Three obligations keep running while the car rests: the annual IUC, compulsory insurance and the periodic inspection. Each follows its own calendar, and each is easy to miss from abroad.
This guide sets out what the rules say, with links to the primary sources at the end. It is guidance, not advice — the rules change, and your position depends on your circumstances.

IUC: THE ANNUAL ROAD TAX.
The Imposto Único de Circulação is paid once a year by the registered owner, during the month of the car's registration anniversary. A car first registered in May is due every May, whether it has covered ten thousand kilometres that year or none.
There is no exemption for a car that is not driven. Liability runs, in the words of the official guidance, until you cease to be the owner or until the registration is cancelled. Storage, however long, changes neither.
Payment is straightforward from anywhere: online through the Portal das Finanças, with your NIF and password or the Chave Móvel Digital, or by MB Way, Multibanco, homebanking or at CTT.
Paying late is commonly reported to bring a fine that starts at around €25 and rises to a minimum of €50 once Finanças acts, with late-payment interest accruing daily; after 90 days the debt can pass to enforced collection (execução fiscal). Confirm the current position with the Autoridade Tributária.
INSURANCE: STILL COMPULSORY.
Correct as of September 2026 — confirm with IMT / Autoridade Tributária
Decreto-Lei 291/2007 requires third-party liability cover for vehicles habitually kept in Portugal. The one exemption that matters to a stored car is narrow: a vehicle temporarily or permanently withdrawn and prohibited from use through an administrative procedure.
Storage is not that procedure. The procedure is cancelamento de matrícula at IMT, available when a car is no longer used on public roads, for a maximum of five years before it is either reinstated or cancelled definitively.
In practice, keeping the car insured is usually the simpler course. Cancelling the registration takes the car off the road entirely — it cannot be driven until the registration is reinstated — which suits a long restoration or a genuinely indefinite lay-up far better than a seasonal stay. If the car will rest for months rather than years, speak to your insurer about the cover it offers for a car kept in secure storage, and confirm transit cover if it will travel by carrier.
IPO: THE INSPECTION CALENDAR.
Correct as of September 2026 — confirm with IMT / Autoridade Tributária
Passenger cars are first inspected four years after first registration, then every two years until the car is eight years old, and every year after that. The calendar runs whether or not the car moves.
A lapsed inspection on a car that stays parked is not itself fined. The consequence is practical: the car cannot legally be driven on public roads until it has been re-inspected. Driving it without a valid inspection carries a fine of €250 to €1,250 under Decreto-Lei 144/2012.
The simplest discipline is to note the due date before you leave. An inspection that falls in the middle of a stay is easy to arrange in advance, and awkward to discover on the morning you want to drive.
NON-RESIDENTS WITH AN EU-PLATED CAR.
Correct as of September 2026 — confirm with IMT / Autoridade Tributária
A car registered elsewhere in the European Union follows a different set of rules. Under Article 30 of the Código do ISV, a non-resident driving their own EU-registered car may keep it in Portugal under temporary admission, with vehicle tax suspended, for up to six months — consecutive or not — in any twelve-month period. The press often rounds this to 183 days; the legal text says six months.
Beyond that, ISV and the legalisation of the car in Portugal apply. The detail depends on your residence status and how the car entered the country, and it is not something to improvise: speak to a customs adviser before the six months run out.

QUESTIONS OWNERS ASK.
Do I have to pay IUC if my car is not being driven?
Yes. There is no exemption for a car that is simply not used. IUC is owed every year by the registered owner until they cease to own the car or its registration is formally cancelled. It falls due in the month of the car's registration anniversary.
Can I cancel the insurance on a car in storage?
Only if the car is formally withdrawn from use. Under Decreto-Lei 291/2007, a car habitually kept in Portugal must carry third-party cover; the exception is a vehicle withdrawn by an administrative act — in practice, cancelamento de matrícula at IMT, for up to five years. Storage alone does not remove the obligation.
What happens if the IPO expires while the car is stored?
A car sitting unused with a lapsed inspection is not itself fined, but it cannot legally be driven on public roads until it has been re-inspected. Driving it without a valid inspection carries a fine of €250 to €1,250. Keep an eye on the due date before you plan to use the car again.
How often does a car need an IPO in Portugal?
For passenger cars, the first inspection is due four years after first registration, then every two years until the car is eight years old, and every year after that.
How long can a non-resident keep an EU-registered car in Portugal?
Under Article 30 of the Código do ISV, a non-resident may keep their own EU-registered car in Portugal under temporary admission for up to six months, consecutive or not, in any twelve-month period. Beyond that, ISV and legalisation apply. Take advice from a customs adviser about your own position.
Can Vault 620 arrange the IPO while I am away?
Yes. IPO inspection is part of our concierge service: coordinated on your behalf and reported back plainly, priced on request. Tell us when the inspection falls due and we will plan it into the car's stay.
