A customs officer in a Mediterranean marina once asked me to prove my boat was VAT-paid. I opened a plastic wallet, handed him the original builder's invoice and the previous owner's VAT documentation, he glanced at them, nodded, and that was the entire encounter. Two minutes. The sailor on the next pontoon, asked the same question a week earlier, had nothing aboard and spent the next fortnight emailing a broker in another country trying to reconstruct a paper trail that should have travelled with the boat.
The difference was not luck. It was a folder. This is how to build one.
Why VAT status is the question that matters
For a boat cruising EU waters, the status that opens or closes doors is whether the vessel is in free circulation with VAT accounted for. A VAT-paid boat moves freely. A boat that is not VAT-paid is either operating under a relief such as temporary admission, or it has a liability waiting to crystallise, potentially at 20 per cent of its value.
That is a large number on any cruising boat, which is why customs ask and why buyers ask. The whole topic of what counts as paid, not-paid and how it travels with a boat is worth reading in full in the VAT status of a boat in EU waters. This piece is narrower: what physical and digital evidence you keep, and how you organise it.
The documents that actually prove status
There is no single magic certificate. VAT status is proved by a chain of evidence, and the more of the chain you hold, the stronger your position. The pieces worth gathering:
- The original invoice from the builder or first dealer showing VAT charged, ideally the manufacturer-to-dealer invoice as well as the dealer-to-first-owner one. This is the foundation and, unlike a transit document, it does not expire.
- The bill of sale for each subsequent change of ownership, building a chain from first sale to you.
- Any VAT receipt or import declaration if the boat was imported into the EU and VAT paid on entry.
- For older boats, evidence the vessel was in the EU on 31 December 1992 and moored there on 1 January 1993, which can confer deemed VAT-paid status under the grandfather provisions.
- The registration document and CE marking or build details, which tie the paperwork to this specific hull.
Keep originals where you can and clear copies of everything. A chain of invoices that does not need renewing is far more durable than a transit certificate that does.
The T2L is gone: meet PoUS
Here is the change that catches returning cruisers out. The old paper T2L (and T2LF for movements touching non-VAT territories), long used as proof a boat held Union status, has moved into a new electronic system. Since the PoUS, Proof of Union Status, rollout reached its second phase in August 2025, the proof is generated and held digitally rather than as a stamped paper form, and for maritime movements a customs goods manifest can now also serve as digital proof.
In practice this means two things for a boater. First, if someone tells you to "get a T2L stamped at the customs office", that advice is now dated, and you should check the current PoUS procedure for your situation. Second, the underlying logic is unchanged: you are still proving the boat is Union goods, just through an electronic record. The durable invoice chain above remains the better long-term backbone, because it never expires and does not depend on a system login.
Build the file before you need it
A customs question is the wrong moment to start looking for paperwork. Build the file in calm water. Mine lives in a waterproof wallet aboard plus a scanned copy in cloud storage plus a copy left with someone ashore. Belt, braces and a spare.
What goes in:
- The VAT invoice chain and bills of sale, oldest first.
- The current registration certificate and proof of ownership in your name.
- Insurance documents showing valid third-party cover, which French marinas and officials routinely want.
- For a non-EU boat, dated records of when the boat entered and left EU waters, the lifeblood of any temporary admission claim.
- Copies of any PoUS or customs status records you have obtained.
If you bought the boat in France, the moment of purchase is when you assemble most of this, which is why I treat it as part of registering a boat purchase with French customs. Picking up the file from the seller at handover is far easier than chasing it years later.
The non-EU case is different and stricter
If your boat is non-EU and not VAT-paid, your file is not proving VAT was paid, it is proving you are entitled to the relief that means you do not owe it yet. For most visiting Americans, Australians and post-Brexit British owners that relief is temporary admission, and its entire validity rests on showing when the boat entered EU waters and that the 18-month clock has not run out. Without dated entry evidence, a perfectly legitimate position becomes impossible to defend at the quayside. The rules and the clock are set out in the 18-month temporary admission rule for non-EU boats, and the file you build to support it is arguably more important than a VAT-paid boat's file, because the consequences of failing to prove it are immediate.
The grandfather boats and the awkward cases
Older boats have their own quirk worth understanding, because it catches buyers of classics off guard. A boat that was in the EU on 31 December 1992 and lying in an EU port on 1 January 1993 can qualify as deemed VAT-paid under the transitional provisions that came in with the single market, even if no VAT was ever explicitly charged in the way a modern invoice shows. If you own or are buying such a boat, the evidence you want is documentary proof of where the vessel was on those dates, an old registration, a berthing record, a marina invoice from the period. It is exactly the sort of paper that gets thrown away, so if it exists, treasure it.
The genuinely awkward case is the boat with a broken chain: built decades ago, sold privately several times, papers lost along the way. Here you assemble whatever you can, a registration history, any surviving invoice, evidence of long EU residence, and accept that your position is "probably fine but imperfectly documented". That is worth knowing before you buy such a boat, because a thin file is a price-negotiation point and a future headache. A surveyor and a careful look at the papers matter as much as the hull, a theme I return to in the hull inspection tips for buying a used sailboat.
Keep it current, not just complete
A file is not a museum. Update it. Each time ownership changes, add the bill of sale. Each time you cross the EU frontier on a non-EU boat, log the date and port. If you obtain a PoUS record for a particular movement, save the reference. Insurance renews annually, so swap the certificate. A file that was perfect three years ago but stops there can leave a gap precisely where an official looks. Ten minutes after each event keeps it honest.
When the file pays for itself
The folder earns its keep in three moments, and all three are predictable.
The first is a routine inspection. French officials, including the Gendarmerie Maritime, can and do ask to see a boat's papers, and a tidy file turns an interrogation into a nod. What they typically check is in carrying your boat documents and what the Gendarmerie Maritime checks.
The second is taking a long berth, because some marinas now ask to see status evidence when you sign an annual contract on a foreign-flagged boat.
The third, and the one that pays best, is selling. A buyer who can see clean, complete VAT and ownership documentation pays more, pays faster, and walks away from a boat that cannot prove its status. The file you build for yourself becomes the file that closes your eventual sale.
None of this is glamorous. But a boat is one of the few things you own where a missing piece of paper can cost a fifth of its value, and the fix is a folder you assemble once and keep dry. Build it before the officer asks, not after.
