Do I need to pay VAT if I sell used items online?

It depends on the situation, but basically if you're a private person selling used stuff occasionally, like clearing out your wardrobe, you normally don't need VAT. But if you start doing it regularly and it looks like a commercial activity, then yeah you do have to register and pay VAT. Best thing is to check with the Tax Authority because each case can be different, especially if you're gonna be selling things more systematically, like stuff you buy and resell.

Hey guys, you're right, but let me add a detail that's kind of important based on my own experience here in Brazil! The VAT thing is a Portugal deal, you know, but here we have a pretty similar situation with taxes.

If you're selling used stuff occasionally, like that vase you don't want anymore or some books you're too lazy to keep, normally nobody cares! Now, when it starts becoming something more systematic - like you're selling regularly, you're always posting new stuff, you're making decent money - then the authorities start paying attention and you're gonna have to get legit! It's that scale thing that makes all the difference.

What I recommend is being honest with yourself about it! If it's really occasional, like cleaning out your closet every few months, you're good. But if it turned into income you're counting on, better find an accountant or someone who knows about taxes in your country, because it varies a lot out there! This can save you a lot of headaches down the road, trust me!

True, but I'd add something important that a lot of people forget: even if you're selling occasionally, if you're making decent money from it month after month, the tax authority can consider it a professional activity and then you need to register properly. Basically, the line is pretty thin between "I'm cleaning out my closet" and "I'm reselling stuff to make money," you know? If it's rare and sporadic, don't sweat it because it's probably fine, but if it's become a regular thing (like selling every weekend), you better get proper information from an accountant or your city hall because every place has its own rules.

I agree with what they said, but I still think it's worth consulting the Tax Authority if you start selling regularly, because the line between occasional and professional is kind of blurry and you don't want any surprises. If it's just clearing out your wardrobe every now and then, you're fine.
