The first time I heard a fellow cruiser say "the clock has started" I had no idea what he meant. He was an American who had sailed his boat into Antibes, and he was counting days. He had eighteen months, he said, and after that the French would expect VAT or they would expect the boat gone. He was right, and a year later I understood exactly why he kept a Tunisia stamp in his ship's papers like it was a passport.
This is the temporary admission regime, and if you own a non-EU boat and want to keep cruising France, you have to plan around it from day one.
The 18-month rule in plain terms
Temporary admission (TA) lets a boat registered outside the EU stay and cruise in EU waters for up to 18 months without paying import VAT or duty. It exists so that genuine visitors are not taxed like importers. The headline VAT rate you are avoiding is 20% in France, charged on the boat's value, so on a 150,000-euro yacht the relief is worth around 30,000 euros. That is why people take the rules seriously.
The conditions are strict and France enforces them harder than most:
- The owner must be established outside the EU for tax purposes.
- The boat must be for private pleasure use only, never chartered or used commercially while under TA.
- Everyone using the boat under TA must be non-EU resident. Lend it to an EU-resident friend who takes it out alone and you can break the relief.
Read the basics of the regime in the overview on the 18-month temporary admission rule for non-EU boats before you rely on any of this.
When does the clock start, and can you pause it
The clock starts when the boat enters EU waters. The good news is that the 18 months do not have to be consecutive, and the relief can be suspended. If you lay the boat up in a bonded arrangement, or if it physically leaves EU waters, the running of the period stops.
In practice the most common way cruisers manage it is by leaving the EU before the 18 months are up and coming back in to start a fresh period. There is no minimum time you must spend outside EU waters. What matters is proof: marina receipts, a customs stamp, fuel invoices from a non-EU port. From France or the western Med the usual targets are Tunisia, Morocco, Montenegro, Albania or Gibraltar. A weekend in a non-EU marina with the paperwork to show for it resets you for another 18 months.
Distances matter when you plan this. From the Cote d'Azur, Gibraltar is a long slog of well over 600 nautical miles each way, so for boats based in the western Med the realistic non-EU port is Tunisia, roughly 200 to 250 miles south from the Hyeres area, or a hop across to the North African coast. From an Atlantic base, the boat going home to the UK or the US is leaving EU waters anyway, which solves the reset for free. The point is to put a non-EU landfall somewhere into a passage you would half want to make regardless, rather than burning a whole cruising season on a tax errand.
Where France is stricter than the brochure suggests
Here is where visitors get caught. French customs have told cruisers directly that France does not extend the 18-month period the way some other member states will, and France does not recognise bond or guarantee documents issued in other countries. So a plan that worked for someone in Italy or Greece may not save you in Marseille.
There is a second trap that surfaced in recent enforcement. France has argued that simply sailing out past the 12-mile limit and back does not count as a genuine export. They want evidence the boat actually called at a third-country port, Gibraltar or an Algerian or Tunisian marina for example, not just that it crossed an invisible line offshore. So the reset has to be a real visit to a real non-EU harbour, documented. Treat a "quick lap outside the limit" as worthless.
The single biggest mistake, though, is residency drift. If you, the owner, become tax-resident in the EU, you lose the right to use TA at all, immediately. People who buy a place in France, or who quietly overstay and become resident in practice, can find their boat has gone from legal to liable overnight. The Schengen 90/180 rule and your tax residency are different things, but both matter, and I untangle the movement side in the guide to the Schengen 90/180 day rule for boaters.
Your three real options past the deadline
Once 18 months is looming, you have three honest routes.
First, reset by leaving. Sail to a non-EU port, get it documented, come back. This is what most non-resident owners do, year after year. It costs you a passage and a few nights' berthing, nothing more in tax terms.
Second, import the boat and pay the VAT. This ends the clock-watching for good and turns the boat into Union goods that can stay forever and sell easily to European buyers. On a low-value boat the VAT is modest and this is often the sensible end-state. I work through the maths in importing a boat into France, including how the customs value is set and when the bill is bearable.
Third, lay the boat up and suspend the period. If you are going home for a season, putting the boat into a properly recorded lay-up can stop the clock so you arrive back with time still on the meter. Confirm the arrangement in writing with the yard and keep the dates.
What you must not do is let the deadline pass quietly and hope nobody checks. If French customs find a non-EU boat that has overstayed TA, the consequence is assessment of the import VAT plus duty, and potentially penalties on top. On a mid-size yacht that is a five-figure surprise, and the boat can be detained until it is paid. Customs duty on a yacht is around 1.7% of the value, and then the 20% VAT lands on top of value plus duty, so a 150,000-euro boat caught overstaying is looking at roughly 2,550 euros of duty and over 30,000 euros of VAT before any fine. That is the whole reason the cruising community treats the reset as gospel.
A quick word on insurance, because it ties in. If your boat ever falls foul of TA and gets detained, your insurer is not going to thank you, and several policies carry geographic and use clauses that assume you are compliant with local customs rules. Check yours before you cut a reset deadline fine. I cover the cruising-area and liability side in the guide to insurance for a foreign-flagged boat cruising France.
Keep a paper trail like your wallet depends on it
Mine lives in a plastic folder by the chart table: every entry and exit, marina invoices showing dates and locations, the Tunisia and Gibraltar stamps, fuel receipts from non-EU ports. When a douane officer steps aboard, and on the south coast in summer they do, the difference between a five-minute chat and a very bad afternoon is whether you can show, on paper, exactly where the boat has been and when the clock last reset.
The American in Antibes had it sorted. He treated the 18 months as a rhythm, not a threat, planned a North African cruise into every other winter, and never once had a problem. That is the trick. Build the reset into your cruising plans instead of panicking at month seventeen, and France stays the pleasure it should be.
