Yes — and with antiques and vintage that is almost always the sensible start.
Yes. For antiques and vintage a secondary occupation is almost always the sensible start, because your money is tied up in pieces rather than sitting in your account. In Belgium, if your net taxable income stays under 1,922.16 euros a year you pay no social contributions as a secondary occupation. As a main occupation you pay a minimum contribution every quarter, even in a quarter without sales.

That last point is exactly the risk of switching too early. A second-hand business buys in spring and sells in autumn; the contributions run on regardless.
As a main occupation the Belgian social contributions come to 20.5 % of net taxable professional income, plus the management fee of your social insurance fund. Above 75,024.54 euros the rate drops to 14.16 %.
Belgian social contributions as a main occupation
On net taxable professional income, plus the management fee of your social insurance fund.
More than your net salary. Between your margin and what stays in your account sit the VAT on your margin, your fixed costs, social contributions of 20.5 % and income tax. Replacing a salary therefore means making not that amount in margin but considerably more — every month, including the months when nothing sells.
In Belgium, 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 in 2026, 26,000 euros from 1 January 2027 — you charge no VAT, but you are still a taxable person. That distinction matters: compulsory e-invoicing applies to you as well. In the UK you only need to register for VAT above £90,000 of turnover (VATA 1994 Sch. 1 para 1(1)(a)).
