Cross a Mediterranean border on your own keel and you cross a tax border too. Every country in the basin has its own cocktail of cruising fees, charter rules and VAT quirks, and they change often enough that yesterday's forum thread is not a reliable source. If you keep a boat in the Med, or you are thinking about moving one down, you need a working map of what each flag state actually wants from you. Here is the practical picture for Greece, Croatia, Spain and Italy, aimed at owners rather than accountants.
Greece: the TEPAI cruising tax
Greece introduced its cruising fee, the TEPAI (Τέλος Πλοίων Αναψυχής και Ημερόπλοιων), in 2019 and has kept it in place since. It applies to every pleasure craft over 7 metres that uses Greek waters, regardless of flag. That includes EU boats on a routine summer cruise from Italy, Turkish-based boats popping into the Dodecanese, and long-term liveaboards in Corfu.
The fee scales with hull length in one-metre bands and is paid monthly. As a rule of thumb, a 12 metre boat pays around €100 per month at the standard rate, and it climbs sharply above that. You can pay by month, by six months or by year, and there is a discount, typically around 30%, if you settle twelve months in advance. Boats permanently based in Greek marinas on annual contracts also get a discount.
What catches owners out is not the amount, it is the paperwork. TEPAI is paid through the AADE electronic portal (or an authorised representative), and the receipt has to be aboard. Coast guard checks in the Cyclades and the Ionian are routine in July and August. Common mistakes:
- Paying for the wrong length band because the tax uses overall length, not hull length.
- Letting a monthly payment lapse when the boat is technically in the water but "not cruising". If she is afloat in Greek waters, she owes.
- Assuming your charter operator has paid it. On a bareboat you almost always have to check.
Charter boats registered under the Greek flag have their own regime, with professional licences and crew requirements that are stricter than in most neighbouring countries.
Croatia: vignette, safety fee and the charter question
Croatia does not have a monthly cruising tax in the Greek style. Instead, before you can navigate in Croatian waters, foreign-flagged pleasure craft with an engine over 5 kW or over 2.5 metres LOA must buy a vignette at the first port of entry (Umag, Pula, Rijeka, Zadar, Šibenik, Split, Ploče, Dubrovnik and a handful of others). The vignette is valid for one year from the date of issue, and it bundles several things:
- The navigation safety fee.
- The lighthouse fee.
- The information card / crew list, which you must keep updated when guests change.
Price depends on length, engine power and whether you carry accommodation aboard. A 12 metre sailing yacht typically pays a few hundred euros for the year, a larger motor yacht considerably more. There is a sojourn tax on top, charged per crew member per day, which many owners pay as a lump sum at check-in.
The bigger topic in Croatia is chartering. A non-Croatian flagged boat cannot legally do commercial charter starting and ending in Croatia. If you want to run your own boat as a business there, you are looking at Croatian registration, Croatian VAT registration and a licensed local operator. This is exactly the kind of decision where the wrapper matters more than the rate, and it is worth reading our note on buying a boat through a company before you commit to a structure.
Spain: the matriculación tax and charter licences
Spain has the reputation of being the most awkward tax jurisdiction in the western Med, and it is mostly deserved. The core issue is the Impuesto Especial sobre Determinados Medios de Transporte, usually called the matriculación tax or IEDMT. It is a 12% one-off tax that applies to:
- Boats over 8 metres registered under the Spanish flag.
- Boats owned or effectively used by Spanish residents, regardless of flag.
- Boats used for commercial charter starting in Spanish waters unless they qualify for an exemption.
The charter exemption is the one most non-Spanish owners try to use. It is available, but it requires a proper commercial setup, a Spanish tax representative, and demonstrable third-party charter activity. Using it as a fig leaf for private use is the classic way to lose the exemption on audit, along with penalties.
On top of that, Spain enforces the EU Temporary Admission regime tightly for non-EU flagged boats. If you have a boat with a British, Turkish or Channel Islands flag, the customs clock matters. Our piece on the 18-month rule after Brexit covers how that clock actually runs and where owners get bitten.
Beyond IEDMT and VAT, expect harbour fees (T-0, T-5) that get passed through in your marina bill, and Balearic charter rules that differ in detail from the mainland.
Italy: the quietly simpler option
Italy has had a colourful history with pleasure-boat taxes. The 2011 "tassa di stazionamento", introduced by the Monti government, was watered down and eventually scrapped for most sizes, and the country now has no general annual possession tax on recreational craft below a large threshold. For most owner-operators of boats up to 24 metres, the picture is much simpler than in Greece or Spain:
- No monthly cruising tax.
- No vignette to buy on arrival.
- Standard VAT-paid status is expected for EU-flagged boats, temporary admission for third-country boats.
Where Italy gets interesting is charter VAT. Italy applies a place-of-supply logic to yacht charter that depends on where the boat is actually used, with a reduced effective VAT rate when the charter takes place partly outside EU waters. The rules have been rewritten several times to align with EU guidance, and the current version relies on tracked navigation data to prove time outside the EU. That last point is worth underlining: without proper logs from the boat's own systems, you cannot claim the reduction. This is the kind of thing an honest reading of the exemptions available to owners tends to overlook.
The other Italian expense to plan for is mooring. Berths in Sardinia, Liguria and the Amalfi coast are among the most expensive in the Med in July and August, and long-term contracts often require Italian tax IDs.
What to do before you move the boat
Whatever combination of countries you plan to visit, a few habits make cruising-tax season much less stressful:
- Keep the paperwork aboard, not on a laptop at home. Registration document, VAT status proof (T2L, VAT invoice or equivalent), insurance certificate in the local language when available, radio licence, skipper qualifications. Coast guards want originals or clean scans on the phone.
- Log your entries and exits. A dated fuel receipt in Bonifacio and another in Porto Cervo three days later is the sort of evidence that resolves a temporary admission dispute in ten minutes instead of ten weeks.
- Know your length exactly. Cruising taxes almost always band by LOA, and "about 12 metres" and "12.4 metres" are two different price points.
- Do not assume reciprocity. Paying TEPAI in Greece does not exempt you from a Croatian vignette, and vice versa. Each country's fee is for the use of its own waters and services.
- Separate private and charter use in writing. If you occasionally rent the boat out, the log has to show it. Backdating never survives an inspection.
Owners who are already thinking about the economics of ownership will recognise this as the same discipline needed to actually make a boat pay for itself: precise records, honest categorisation of use, and a boat that generates the data to back it all up. And if your home port is French, none of the above replaces your obligations at home, so check where you stand on the TAEMUP, the annual French boat tax before you leave the dock.
The data question
The theme running through all four countries is the same: tax authorities increasingly want proof of where the boat was and when. Greek TEPAI receipts are timestamped. Italian reduced-rate charter VAT depends on tracked position outside EU waters. Spanish IEDMT charter exemptions rest on documented commercial use. Croatian crew lists have to match reality. A boat that logs its own position, engine hours and usage automatically, and pushes that record to a place you can retrieve it from months later, turns most of these disputes into a five-minute export. This is precisely what the Oria Box is designed to do, and it is why owners cruising multiple jurisdictions tend to be the first to install one. What would your last three seasons of logs look like if a Guardia di Finanza officer asked for them tomorrow?
