For information only. This article is an editorial orientation resource. It does not constitute legal, tax or customs advice. The rules governing diplomatic vehicle exemptions vary by country and change periodically. Always verify the current position with your mission’s administrative office and the relevant customs authority before purchasing, transferring or selling a vehicle.
The customs and tax relief on a diplomatically-registered vehicle is one of the most practically significant privileges of a posting. In France, Switzerland and Austria, three of the most common diplomatic posting destinations in Europe, the exemption from VAT and, where applicable, from national vehicle consumption taxes represents a material saving on the cost of a vehicle. What is less often explained clearly at the time of purchase is the condition attached to it.
The condition is simple: the vehicle must be held for two years before it can be sold, transferred or taken out of the host country without the deferred taxes becoming payable.
What the two-year rule means in practice
The relief is not a cancellation of the tax. It is a deferral, conditional on compliance with the holding period. When you purchase or import a diplomatically-registered vehicle, you sign a commitment to comply with customs and fiscal regulations for the duration of your entitlement. The deferred taxes remain in the background. The two-year clock, which in France runs from the date the DGDDI issued the franchise authorisation rather than the date of purchase, determines when those taxes either expire or crystallise.
If you sell the vehicle before two years have elapsed, the customs and tax obligations that were deferred become payable. The buyer, unless they themselves hold the same exemption, cannot take ownership of the vehicle without those obligations being settled first.
The three situations where the rule becomes relevant
Early transfer or posting change is the most common trigger. A diplomat reassigned after fourteen months needs to decide what to do with a vehicle purchased under diplomatic plates. The options are: take the vehicle to the next posting (which involves separate customs procedures in the new country), sell it to another diplomat holding the same exemption (who then takes on the remainder of the two-year obligation), or regularise the taxes with the host country’s customs authority and sell to a private buyer. None of these is complicated, but all require advance planning.
End of mission at or after two years. Once the two-year period has elapsed, the vehicle can be sold freely in the host country or taken abroad without the deferred VAT becoming payable. The customs authority issues a clearance certificate (in France, the Certificat 846A from the bureau de douane) confirming the regularisation. This certificate is required for re-registration of the vehicle in a standard series. Without it, the buyer cannot register the vehicle in their own name.
Departure before two years without selling. Some diplomats leave their posting without selling or regularising the vehicle, intending to sort it out later. This creates complications. The vehicle remains on diplomatic plates, the customs obligation remains open, and the mission remains responsible for the regularisation. Most missions have procedures for handling this, but it adds administrative burden and can create delays for whomever needs to close the file.
What to do before you leave
Raise the vehicle situation with your mission’s administrative office no later than six to eight weeks before your departure date. The bureau de douane needs time to process the clearance certificate. If you intend to sell before the two years are up, the mission needs time to determine whether an exception is available. Exceptions exist in most countries for early departure, but they require a formal application and are not automatic.
The two-year rule is not a trap. It is a condition of the exemption that is disclosed at the time of purchase. The practical problem is that it tends to be explained once at the beginning and then forgotten until it matters, usually at the worst possible moment.
