Sole trader vs. freelancer: what's the difference actually?




The terms freelancer and sole trader are often used interchangeably, as if they're the same. Yet they don't mean exactly the same. The difference is subtle, but good to know. This article clearly explains how the terms relate to each other.
A sole trader business is a legal form: the legal form in which you run your business. With a sole trader business, you and your company are the same for tax purposes; you pay income tax on the profit and are personally liable. It's the most chosen legal form for starting entrepreneurs.
ZZP stands for self-employed without staff. That's not a legal form, but a description of how you work: as a self-employed person without people employed. A freelancer usually has a sole trader business, but could in theory also have another legal form.
In short: freelancer says something about how you work (alone, without staff), sole trader business says something about your legal form. Most freelancers have a sole trader business, which is why the terms often coincide in practice. That's why they're used interchangeably.
For your tax and liability your legal form counts, so the sole trader business. Whether you call yourself a freelancer doesn't change that. It's good to know the distinction, so you know that tax rules concern your legal form, not the label freelancer.
