Put simply, we are an unpaid tax collector for the government. We collect from you and pay over to HMRC. For this we can reclaim the VAT on our own purchases and allowable expenses.
If your business is registered for VAT, the normal rules apply as per guidebook 700. If it is for business use, you can reclaim the VAT. Different rules apply if the reduced rate of VAT is being used. If you are not registered for VAT there is very little you and everyone can do, unfortunately.
To clarify, the circumstances in which we do not charge VAT are as follows:
UK Forces personnel who are based outside the UK who also qualify for VAT free, delivered by BFPO. Verification is required.
Channel Islands customers. Status verified by address.
VAT Registered customers in another EU country, where the delivery is to that country. Verification is required.
None EU customer. Status verified by address.
UK Customer with VAT Exemption. Verified by certificate. If this status applies to you, you will know already.
