Bought a laptop, but it won't be available until 2020. How does it work with VAT?

The question is already above. Will the whole 19% be due again next year or will it be after the order date?

Do you mean 2021?

You get the invoice after collection - or pay, unless nothing else is changed by the legislation, the 19% VAT.

If it is delivered in 2020, it will happen this year. When delivery takes place in 2021, the price for private individuals will not change.

Eh, yes of course in 2021. Oops.
