I posted this on another thread a couple of months ago:
After further
research, from the RYA and CA in the UK, it looks as though after 3 years the original owner has a good chance of avoiding a 2nd dose of VAT, though not a new owner.
Here's the UK Cruising Association's interpretation (updated 24jan24)
D) Returned Goods Relief - UK and EU
Goods (including yachts and their equipment) can be re-imported into the UK or the EU without payment of VAT in certain circumstances under an arrangement called Returned Goods Relief (RGR).
The conditions that apply to RGR are similar in both the UK and the EU. For RGR to be available:
(a) the vessel must not have had more than "running repairs" to it during its period of export that do not increase its value;
(b) the goods must be returned to the UK or the EU (as applicable) within 3 years or, if they are returned outside the 3 year period:
(i) on a return to the EU there are "special circumstances" to justify the waiver of the 3 year requirement; and
(ii) on a return to the UK, the normal three-year time limit will be waived by HMRC for personal effects (including yachts) which are being returned to the UK for the personal (non-commercial) use of a UK resident person, without the applicant needing to prove that the effects could not be returned within the normal time limit
(c) the person importing the goods is the person who originally exported them.
The EU requirement for "special circumstances" if a return is made outside the 3 year period is assessed on a country by country basis. By way of example, pre-Brexit the UK rules stated that the 3 year period may be waived "to account for special circumstances where HMRC considers that it would be reasonable to do so".
In order for UK RGR to be claimed on an entry to the UK, Form 1331 must be completed. If the return is made outside the 3 year time limit an application for a waiver of the 3 year time requirement must also be made to HMRC on entry to the UK (through the Yachtline reporting processes as set out in HMRC Notice 8). As stated above, as long as the UK RGR conditions are satisfied the 3 year time limit will be waived by HMRC.
