The boat has been moored for three years in Santa Cruz, Puerto Portals or Torrevieja. It runs well, the berth is paid for and it still carries the flag or registration from the country where you previously lived. Then one of those moments arrives: the neighbour at the next berth mentions an inspection over coffee. Or the marina asks about Spanish registration. Or you want to sell and the buyer asks whether the boat is correctly registered for use in Spain.
From that point on, many foreign owners discover that the answer is scattered across maritime, tax and insurance rules. Online, you mainly find service providers selling registration packages or advisers explaining one isolated step. What is missing is a simple answer to a simple question: as a resident or non-resident owner, do I have to register, and if so, in what order?
The answer is less dramatic than it first appears, but it depends on two figures that have nothing to do with each other: your tax residence and the length of your boat. That distinction gets lost in almost every explanation.
- There is no general requirement in Spain to change a boat’s flag. What the law requires is matriculación definitiva, and that depends on the owner’s residence, not the berth.
- If you are resident in Spain and use your boat here, you generally have 30 days from the start of use. The period becomes 60 days only when you move to Spain and only if the relocation exemption actually applies.
- The obligation is not enforceable if, within the same period, the registration tax is declared and paid or an exemption is recognised by the tax authority. This is stated in the First Additional Provision of Ley 38/1992 and is the point most summaries leave out.
- Boats up to twelve metres with CE marking are exempt from registration under the Spanish flag, matriculation and clearance as long as they remain in Spanish territorial waters and within their design category (Real Decreto 1435/2010, Article 8). They still fly the Spanish flag.
- Registration tax applies above eight metres of hull length: 12% of the value on mainland Spain and the Balearic Islands, 11% in the Canary Islands, and 0% in Ceuta and Melilla. Jet skis are taxable regardless of length.
- Up to eight metres, no registration tax is due. If the boat is matriculated, a declaration (Modelo 06) must still be filed before registration.
- If you move to Spain with your own boat, you can avoid the tax completely if five conditions are met. One of them is a twelve-month holding period after registration.
- Third-party liability insurance is compulsory and proof of cover is required during the procedure. Without it, you cannot complete one of the stages.
Do you actually have to register your boat in Spain?
The common assumption is that anyone who lives in Spain and owns a boat must switch it to the Spanish flag. That is not quite correct, and the precise rule can make a significant difference to your costs.
The relevant provision is the First Additional Provision of Ley 38/1992 on Special Taxes. It requires definitive registration in Spain for means of transport intended to be used in Spanish territory by people resident in Spain. The trigger is therefore the owner’s residence, not the harbour and not the flag.
The second paragraph of the same provision contains the relief most summaries omit: the registration requirement is not enforceable if, within the deadline, the registration tax has been self-assessed and paid, recognition of non-taxability or an exemption has been requested, or a declaration of non-taxability has been filed. In other words, the state’s first concern is that the tax position is settled. The registration number is the means, not the objective.
Not resident in Spain no obligation
You are not resident in Spain and use the boat here during holidays or seasonal stays. In that case, the Spanish registration requirement generally does not arise merely because the boat has a Spanish berth. Residence and actual use are the key questions.
Resident in Spain deadline running
You are registered and tax-resident here and use the boat in Spain. From the start of use, you have 30 days to apply for registration or settle the tax position.
Moving to Spain 30 or 60 days
You transfer your normal residence to Spain and bring the boat with you. The period increases to 60 days only if the relocation exemption applies. If one of its five conditions is not met, the period remains 30 days.
Article 65(1)(d) of the same law explains how the deadline is calculated. The key date is the start of use in Spain. If that cannot be established with certainty, the later of two dates applies: the acquisition of the boat or the date from which the owner became resident in Spain.
The little-known exemption for boats up to twelve metres
Alongside the tax rules, there is the maritime administration side: the question of flag, registration number and clearance. And there, one rule simplifies matters for the large majority of recreational boats in Spain.
Article 8 of Real Decreto 1435/2010 is explicit: recreational boats with a hull length of up to 12 metres are exempt from registration under the Spanish flag, matriculation and clearance, provided both the boat and its propulsion system carry CE marking. High-speed craft are excluded.
This exemption has two limits, both stated in the same article. The boat must remain in Spanish territorial waters and must not sail beyond the navigation areas permitted by its design category. If you regularly sail to Portugal, Morocco or from the Canary Islands into open-ocean passages, this simplification no longer applies.
Instead of a registration number, the boat receives a certificado de inscripción issued by the competent maritime district, with an identification number displayed on both sides of the hull. There is still administration involved, but significantly less.
One common misunderstanding should be cleared up here: what is exempt is registration under the Spanish flag, not the obligation to fly the flag. Paragraph 3 of the same article expressly requires these boats to fly the Spanish flag.
The twelve metres in Real Decreto 1435/2010 concern maritime administration: flag, matriculation and clearance. The eight metres in Ley 38/1992 concern the tax authority: registration tax. A ten-metre boat can therefore be exempt from full matriculation and still be taxable. Combining the two figures leads to the wrong answer.
Lista sexta or Lista séptima: the key decision at the start
If your boat is entered in the Spanish ship register, it goes into one of nine lists. Two are relevant to recreational craft, and choosing between them affects tax, inspection intervals and what you are allowed to do with the boat. This is governed by Article 4 of Real Decreto 1027/1989.
| Feature | Lista séptima (7th) | Lista sexta (6th) |
|---|---|---|
| Use | Exclusively private, without profit motive | Commercial, especially charter |
| Registration tax | 12% above eight metres (11% in the Canary Islands) | Exempt as long as the boat is genuinely and exclusively rented out |
| Technical inspection | From six metres, every five years; below six metres exempt | Every five years, plus an intermediate inspection from six metres |
| Typical mistake | Occasional paid trips while the boat remains declared as private | Claiming the tax exemption while the owner still uses the boat personally |
The exemption under Lista sexta is subject to one condition that is regularly overlooked: there is no genuine rental activity if the owner or a related person is allowed to use the boat personally. An owner who places the boat with a charter company but reserves personal-use weeks by contract loses the exemption. The law says so expressly, and discovering it later can be expensive.
The process step by step
Once it is clear that registration will be completed, the order is not optional. The maritime authority wants to see the validated tax declaration before issuing the registration number.
Documents
Prove ownership and technical compliance
- Purchase agreement or invoice
- Proof of deletion from the previous register
- CE declaration of conformity for boat and engine
- ID and proof of nationality
Tax authority
Declare the tax, not just pay it
- Over eight metres: Modelo 576
- Up to eight metres: Modelo 06
- Exemption: request prior recognition
- Keep the validated declaration
Maritime authority
Apply for matriculation
- Apply at the competent maritime district
- Choose the list: 7th or 6th
- Provide proof of insurance
- Pay the registration fee using Modelo 790025
Operation
What you end up with
- Certificado de registro español as the onboard document, replacing the old licencia de navegación
- Navigation-area-specific certificado de navegabilidad with inspection interval
- Identification displayed on both sides of the hull
The information page of the Ministry of Transport and Sustainable Mobility contains a sentence that explains the second stage: once the electronically submitted declaration has been accepted, the printout carrying the eight-digit electronic code is the document used to apply for matriculation. Without this step, stage three is not possible.
There is no serious way to promise a processing time in weeks. It depends on the maritime district, the season and how complete the paperwork is. In practice, it is sensible to begin outside the summer season and not leave the tax-law deadlines until the last day.
Registration tax: what becomes payable above eight metres
The impuesto especial sobre determinados medios de transporte, commonly called registration tax, is the most financially significant part of the process. Under Article 65(1)(b) of Ley 38/1992, the first registration of new or used recreational and sports boats is taxable when they have a hull length of more than eight metres. Jet skis are taxable regardless of length.
The relevant measurement is the eslora de casco, the actual hull length between the outermost structural points. Removable parts such as bathing platforms, bow rails, rudders, masts or fenders are expressly excluded. If a boat is only just over eight metres according to a brochure, check the CE documentation before using the catalogue figure.
| Case | Hull length up to 8 m | Hull length over 8 m |
|---|---|---|
| Private use (Lista 7th), mainland Spain and Balearic Islands | No tax, file Modelo 06 | 12% of the value |
| Private use (Lista 7th), Canary Islands | No tax, file Modelo 06 | 11% of the value |
| Private use, Ceuta and Melilla | No tax | 0% |
| Exclusive charter use (Lista 6th) | Exempt | Exempt |
| Jet ski (Lista 7th) | 14.75%, regardless of length (13.75% in the Canary Islands, 0% in Ceuta and Melilla). In the Balearic Islands, Catalonia, Valencia and Asturias: 16%; Murcia 15.9% and Cantabria 15% | |
| Rowing boats and Olympic sailing classes | Exempt | |
A used sailing yacht with a hull length of 9.60 metres and a purchase price of €78,000 is to be used privately by an owner resident in Spain. It falls under Lista séptima.
Registration tax in the Canary Islands: 11%, around €8,580. On top of that come the registration fee and the navigation certificate fee. The maritime signalling fee does not apply here because sailing boats are only subject to it above twelve metres. The tax is therefore by far the largest single cost in the process.
The purchase price is not automatically the taxable value. For used boats, the authorities work with published average values. That is exactly why valuation belongs before the purchase, not after it.
One point matters for the procedure: even if you pay nothing, you may still have to file. Boats up to eight metres are not subject to the tax, but if they are matriculated, a Modelo 06 declaration is filed in advance, whether the boat is new or used. Without a validated declaration, matriculation is not completed. If a CE-marked boat is only entered under Article 8 and is not matriculated at all, this step also disappears.
Moving to Spain: the exemption many owners miss
If you transfer your normal residence to Spain and bring your boat with you, the registration tax can be avoided completely. The exemption appears in Article 66(1)(n) of Ley 38/1992. It is not automatic, must be applied for, and depends on five conditions that all have to be met.
- Twelve months’ residence abroad. Immediately before the move, you must have lived outside Spain for at least twelve consecutive months.
- Acquired under normal taxation. The boat must have been acquired in the country of origin under normal tax conditions, without exemption and without a refund on leaving the country.
- Six months’ prior use. You must have used the boat for at least six months before leaving your previous residence. A purchase shortly before the move does not satisfy this condition.
- Apply within the deadline. Registration must be requested within the period under Article 65(1)(d), meaning 60 days in a qualifying change-of-residence case.
- Twelve-month holding period. The boat may not be sold for twelve months after registration. If it is, the tax becomes payable at the time of the breach.
The most common reason this exemption is lost is the fourth condition. The move is organised, the boat arrives, and the 60 days expire while the boxes are still being unpacked. After that, the exemption is gone even if all the substantive conditions were met. If you move to Spain with a boat, this is the first date to put in the calendar.
What else is payable: taxes and fees at a glance
Alongside registration tax, there are several smaller costs. Individually they are manageable, but together they explain why a budget that includes only the tax often comes out wrong.
| Item | When it applies | Typical scale |
|---|---|---|
| IVA, IGIC or IPSI | On a new purchase, included in the purchase price | 21% on mainland Spain. In the Canary Islands, 15% for recreational boats over eight metres deck length, otherwise 9.5%. In Ceuta and Melilla according to the local ordinance |
| Impuesto sobre transmisiones patrimoniales | When buying a used boat from a private seller | Rate depends on the Autonomous Community, assessed on the purchase price or official average value |
| Registration fee | On entry and deletion from the register | Based on tonnage, minimum around €19, Modelo 790025 |
| Navigation certificate | Issue and renewal | Around €76 with CE marking, renewal around €53 |
| Maritime signalling fee (T-0) | Motorboats based in Spain under nine metres: once on registration; from nine metres: annually. Sailing boats are only subject above twelve metres, then annually | According to the port authority tariff |
| Port fee (T-5) | Ongoing for berth and port use | According to the relevant port authority tariff |

A note on the fee amounts: they are updated each year. The figures above come from the ministry’s official overview as of 2023 and are intended as an indication, not a quotation. The taxable valuation itself is a matter for the tax authority or a gestoría, not for us.
Documents and technical requirements: Navegabilidad, ITB and CE marking
The process does not end with the registration number. The boat needs documents proving its technical condition, and those documents expire.
The inspections are governed by Real Decreto 1434/1999. It applies to recreational boats from 2.5 to 24 metres. The periodic inspection, commonly called ITB, runs on a five-year cycle. Private boats under six metres in Lista séptima are exempt; boats in Lista sexta are not.
Under 6 m, private exempt
No periodic inspection. Equipment requirements for the relevant navigation area still apply.
From 6 m, private every 5 years
Periodic inspection every five years. From 15 metres, and for wooden hulls from six metres, an intermediate inspection is also required in the second to third year.
Charter (Lista 6th) stricter
Periodic inspection every five years regardless of length, plus the intermediate inspection from six metres.
The second document is the onboard certificate. Since Real Decreto 1435/2010, it is called the certificado de registro español and replaces the former licencia de navegación. Existing boats keep the old licence until a registrable event occurs, such as a change of ownership. At that point it is replaced. Anyone buying a used boat in Spain will therefore usually encounter this change automatically.
Which boat licence do you need in Spain?
Spanish boating qualifications are governed by Real Decreto 875/2014. For foreign owners, the most important questions are when a licence is required at all and which qualification matches which boat.
| Qualification | Maximum hull length | Distance from coast |
|---|---|---|
| Licencia de navegación | 6 metres | 2 nautical miles, daylight only |
| Patrón para navegación básica (PNB) | 8 metres | 5 nautical miles |
| Patrón de embarcaciones de recreo (PER) | 15 metres | 12 nautical miles |
| Patrón de yate | 24 metres | 150 nautical miles |
| Capitán de yate | 24 metres | No geographical limit |
The powers in Article 8 are formulated for motorboats. Anyone who wants to sail a sailing boat also needs the corresponding sailing endorsement.
Under Article 10, no qualification is required only for motorboats up to 11.26 kW and five metres, and sailing boats up to six metres, in each case during daylight and no more than two nautical miles from a sheltered place. This is a narrow exception that in practice covers only small tenders and day boats.
Real Decreto 1188/2025 amends Article 10 with effect from 1 October 2026. From then on, the exemption applies only to private use of motorboats and sporting use of sailing boats. Anyone who rents a boat will need the appropriate qualification from that date. If you intend to charter your boat, include this in your planning.
Where insurance becomes necessary in the process
Third-party liability insurance for recreational boats is compulsory in Spain. The legal basis is Real Decreto 607/1999. It covers all motorised recreational boats, including jet skis, as well as non-motorised boats over six metres. The statutory minimum limits are set out in the same regulation.
For the registration procedure, the practical point is simple: proof of insurance is required at this stage, and without it the process cannot continue. The policy must be in place before the boat is operated and forms part of the documents required in the procedure and during inspections.
Which covers make sense, the difference between third-party liability and comprehensive cover, what limits suit your boat and what the policy costs are separate questions and do not belong in an administrative guide. We explain them in detail on our Boat Insurance in Spain page. If your berth is in Mallorca, there is also a dedicated page on Boat and Yacht Insurance in Mallorca.
One practical point about the order still matters: if the list in which the boat is registered changes, for example from private use to charter, the risk also changes. A policy written for private use no longer matches the actual operation. Tell us before applying for the list change, not afterwards. The points to consider are explained on our Boat Insurance in Spain page.
What many foreign boat owners expect vs how Spain actually works
What many owners expect
Keep the existing flag and paperwork indefinitely
Owners often assume that because their boat was legally registered or documented in another country, nothing changes when they become resident in Spain. They may also assume that a Spanish berth alone decides the issue or that there is no tax consequence until the boat is sold.
How Spain works
Residence, use, deadlines and boat length all matter
For residents, Spanish rules can trigger a 30-day deadline, tax formalities and, depending on hull length and use, matriculation requirements. CE-marked boats up to twelve metres benefit from an important simplification, but the eight-metre tax threshold is a separate issue.
The practical lesson for any foreign owner is that previous-country rules do not carry over automatically. Check your Spanish residence status, the boat’s true hull length, intended navigation area and tax position before assuming that existing foreign paperwork is enough. The same principle applies to other vehicles, as explained in our guide to driving in Spain as an expat.
What this process does not resolve
A guide that only explains what works tells only half the story. The registration process expressly does not resolve three issues.
- Your personal tax position. Whether you are tax resident in Spain, how a boat is treated for wealth-tax purposes and how charter income is taxed depend on the individual case. That belongs with a gestoría or tax adviser, ideally before the purchase.
- The valuation of the boat. The tax authority, not the purchase contract, decides which value is ultimately used. A budget calculated to the last euro is therefore a false sense of precision.
- Trips abroad. The exemption for boats up to twelve metres applies within Spanish territorial waters. If you want to sail to Portugal, Morocco or on open-sea passages, you need full matriculation and the appropriate onboard documents.
Six mistakes we see again and again
Frequently asked questions
Do I have to re-register a foreign boat in Spain if I live here?
Not simply because the boat carries a foreign flag. The key issue is your residence and use of the boat in Spain. Spanish law can require definitive registration or, within the relevant deadline, settlement of the registration-tax position or recognition of an exemption. The safest approach is to check the residence, tax and maritime-registration rules together.
How much time do I have to register?
30 days from the start of use in Spain. If you transfer your normal residence to Spain and intend to claim the relocation exemption, the deadline becomes 60 days. If the start of use cannot be proved with certainty, the later of two dates applies: the acquisition of the boat or the start of your residence in Spain.
At what length does registration tax apply?
Above eight metres of hull length. The rate is 12% of the value on mainland Spain and the Balearic Islands, 11% in the Canary Islands and 0% in Ceuta and Melilla. Jet skis are taxable regardless of length. The rate is 14.75%, 13.75% in the Canary Islands and 0% in Ceuta and Melilla. Several Autonomous Communities apply higher rates: 16% in the Balearic Islands, Catalonia, Valencia and Asturias, 15.9% in Murcia and 15% in Cantabria.
My boat is under eight metres. Do I still have to do anything?
It depends on whether the boat is matriculated. No registration tax is due, but before matriculation a Modelo 06 declaration must be filed with the tax authority, for both new and used boats. Without a validated declaration, matriculation is not completed. If the boat is only entered under the twelve-metre rule and is not matriculated, this step does not apply.
Is it true that boats up to twelve metres do not have to be registered at all?
Almost. Recreational boats up to twelve metres of hull length are exempt from registration under the Spanish flag, matriculation and clearance if both the boat and propulsion system carry CE marking. They must still fly the Spanish flag. Instead, they receive a registration certificate with an identification number displayed on both sides. The exemption applies only in Spanish territorial waters and within the navigation areas allowed by the design category, and it says nothing about tax.
Which authority is responsible?
For tax, the Spanish tax authority, where the declaration is filed electronically. For registration itself, the competent maritime district or harbour master’s office. The order is fixed: the validated tax declaration is the document used to apply for registration.
How often does my boat need a technical inspection?
Private boats from six metres: every five years. Private boats under six metres are exempt from periodic inspection. Commercial boats follow the five-year cycle regardless of length, with an intermediate inspection in the second to third year from six metres. The same intermediate inspection applies to wooden hulls from six metres and private boats from fifteen metres.
Which boat licence do I need in Spain?
It depends on boat length and navigation area. The licencia de navegación covers up to six metres and two nautical miles, daylight only; the patrón para navegación básica up to eight metres and five nautical miles; the PER up to fifteen metres and twelve nautical miles; and the patrón de yate up to twenty-four metres and 150 nautical miles. Without a qualification, you may only operate motorboats up to 11.26 kW and five metres and sailing boats up to six metres, during daylight and no more than two nautical miles from a sheltered place. This exemption becomes narrower on 1 October 2026 and no longer applies to rented boats.
Is boat insurance compulsory in Spain?
Yes. Third-party liability insurance is legally required for all motorised recreational boats, including jet skis, and for non-motorised boats over six metres. Proof of insurance forms part of the registration documents and must be produced during inspections. Which additional cover makes sense depends on the boat, navigation area and use; this is explained on our Boat Insurance in Spain page.
Can I avoid registration tax if I move to Spain with my boat?
Yes, if all five conditions are met: at least twelve months’ residence abroad before the move, normal taxation on acquisition without a refund, at least six months’ prior use at the former residence, an application within the deadline, and no sale during the twelve months after registration. The exemption is not automatic; it must be applied for.
Our advice as an independent broker
The registration process is not impossibly complicated, but it has one awkward feature: it begins quietly. No letter arrives, no authority gets in touch, and the deadline still runs. If you only react when someone at the marina asks, the easiest route has often already been missed.
The three questions that really matter can be answered in an afternoon: what is the actual hull length? Am I resident in Spain, and since when? And where exactly do I intend to sail? Those three answers determine almost everything else, including whether any registration tax is due.
As an independent insurance broker, we are not tied to one insurer. We are not tax advisers and do not provide tax advice, but we know the procedure from everyday work with foreign boat owners in Tenerife, La Palma, Gran Canaria, the Costa Blanca and Mallorca. We can tell you where you are in the process, which documents come next and when it is better to involve a gestoría. And when it comes to the insurance policy, we can handle that in English, including when a claim involves a Spanish insurer or surveyor. The cover itself is explained on our Boat Insurance in Spain page, while owners with a berth in the Balearic Islands can also read our guide to Boat Insurance in Mallorca.
Tell us the hull length, year of manufacture, intended navigation area and since when you have been registered in Spain. We will help classify the case and explain which policy fits and when it needs to be in place. No obligation, and support is available in English.
