Not because the platform reports you. Those are two different things.
Not because the platform reports you. The Belgian FPS Finance says it literally: those thresholds only determine the platform's reporting obligation, not your duty to declare. If you sell your own belongings, that is normal management of private assets. If you buy to resell, you do declare — and from the first euro.
What a platform passes on starts above 2,000 euros of turnover and/or 30 or more sales in one calendar year, counted per platform. Sell 20 items on each of two platforms and neither reports you.
That is exactly why the report is a poor measure of whether you are a dealer. If you are one, the report is not your problem — your records are: without proof of purchase per piece your margin falls away.

This is an explanation, not tax or legal advice. Put your own situation to your accountant.
The Belgian FPS Finance hangs it not on an amount but on what you do: did you buy the goods in order to resell them? Occasional and without organisation, that is miscellaneous income, taxed at 33 % after costs, in box XV codes 1200/2200. Repeated, frequent, with large amounts and organisation, it is professional income, box XVII codes 1600/2600.
Then applying the margin scheme correctly becomes difficult or impossible. The scheme taxes the difference between purchase and sale; without a purchase price there is no margin to tax and you fall back on the normal rules: VAT on the full selling price. In the UK, HMRC says so in as many words.
Vintro Pro keeps, per piece, what you paid, when, and where it came from. Your stock list and your margin VAT build themselves while you work.
