You can only claim back VAT on certain types of vans when bought new - the rate of VRT will determine if it is a commercial vehicle and accordingly if the VAT can be claimed back. The rate of VRT for a commercial vehicle is very low - eg Eur 400 as opposed to 20% to 30% of the purchase price. Basically low rate of VRT then VAT is reclaimable. There may be some exceptions to this rule but very few I believe.
