Frequently asked questions · Starting out as a dealer

When do you count as a dealer rather than a private seller?

Not at an amount. At what you do.

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.

If you sell your own belongings, that is normal management of your private assets and there is nothing to declare. So the distinction is not in how much you sell, but in why you bought it.

Once you are a dealer the margin scheme comes into play immediately: VAT on your profit margin instead of on your full selling price — but only if you can show, per piece, what you paid for it.

Where this comes from

Checked on 2 September 2026 at the Belgian FPS Finance (the thresholds, the three categories and the return codes), the Belastingdienst, economie.gouv.fr and HMRC.

This is an explanation, not tax or legal advice. Put your own situation to your accountant.

Also worth knowing

Do you pay tax on what you sell on Vinted?

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.

Do you need a VAT number as a second-hand dealer?

Anyone buying to resell is acting professionally and registers as a business. If you stay under the small-business exemption — 25,000 euros of turnover in Belgium — you charge no VAT, but you are still a taxable person. That distinction matters: compulsory e-invoicing applies to you as well.
