Do I need to report my earnings if I'm selling on Vinted?

It's not really a matter of "do I have to" yes or no, it depends on how much you're making and how you look at it. If you're selling stuff you already had at home to get rid of old things, technically it's not a business activity and you don't have to declare anything. But if you're doing it systematically and regularly, maybe with significant margins, the tax authority could consider it an activity and ask you to declare it. The line is a bit blurry, though if you're just making the occasional sale nothing really happens; if instead you're doing it almost like a little side gig, it's better to play it safe and declare your income, at least so you don't have problems down the road.

The key thing is that Vinted keeps track of everything and shares the data with tax authorities, so it's better to be proactive than hope they don't notice. If you're selling stuff you already own occasionally, like the odd item here and there, it stays in a gray area; but if you've got a steady activity with real margins, you need to declare it as miscellaneous income. One trick almost nobody mentions: open a file (even just an Excel spreadsheet) where you note what you're selling and at what price, so if the tax authorities ask you've got the numbers ready and don't look like you're making it up as you go. Rather than contacting the Revenue Agency directly, check out forums where people doing the same thing on Vinted talk about how they've handled it, and maybe consult an accountant if your earnings start getting substantial.

I have friends who started selling on Vinted to get rid of stuff, and one of them got a nasty surprise when she found out the platform reports everything to the tax authority. What nobody tells you is that it's not really a question of "should I or shouldn't I," but how much risk you're willing to take. If we're talking about a few listings a year of personal items, it's true that technically it falls under selling used goods (not considered income), but the line gets blurry when Vinted sees you're doing dozens of sales a month.

What I want to add is that the tax office doesn't just look at numbers - it looks at patterns. If you sell ten t-shirts over three years? No problem. If you sell fifty pieces of new clothing, maybe still with tags on, in six months? Vinted itself could suspend your account for suspected commercial activity, let alone the tax authority. And then there's the VAT issue: above certain earnings, you're required to register, and staying under the radar becomes actual illegal activity, not a gray area.

The smartest thing is to do the math: if your annual earnings from Vinted stay under €5,000 and they're genuinely personal items, you're probably fine. If you go over that threshold or if it's clear you're reselling stuff you bought specifically for that, then it's really worth consulting an accountant. They don't cost much for a consultation, and you can sleep easy.

What nobody really emphasizes enough is that Vinted asks for your IBAN for payments, and that trace stays there no matter how much you sell - so the tax authorities can track your transactions even if you think you're flying under the radar. Selling a few things occasionally from home is one thing, but if you start making 50-100 euros a month consistently, it ends up being worth it to declare everything or you risk trouble. Better to get it sorted from the start than end up having to explain weird account movements later.
