Short answer: no, you almost certainly do not need an LLC (US) or a limited company (UK) to start selling online — in both countries you can legally trade as an individual from day one, and most new sellers should. Registering a company is a decision you make when the business grows into it, not a hurdle you clear before your first sale. Below is the honest, country-aware version of what that means and when the calculus changes.
One thing before we start: this article is informational only and is not legal, tax, or accounting advice. Rules differ by country, state, and personal circumstance, and they change. Before you register anything — or decide not to — check with a qualified accountant or solicitor/attorney who knows your situation. With that said, here's the practical lay of the land.
The universal principle: the platform doesn't care
Whatever you're building your store on, the software will happily take orders whether you're a registered company or a person selling from a spare room. Your legal structure is about how you are taxed and how much personal liability you carry — it has nothing to do with whether you're allowed to open a store. You can launch first and formalise later, and the overwhelming majority of successful sellers did exactly that.
So the real question isn't "am I allowed to sell without a company?" You are. The question is "at what point does forming one protect me or save me money?" That answer looks different in the UK and the US, so let's take them one at a time.
Selling online in the UK
In the UK, the default and simplest way to start is as a sole trader. You are the business, the business is you, and there's no company to register at Companies House. What you do need to do is tell HMRC that you're trading so you can be taxed correctly.
A few UK specifics worth knowing:
The "trading allowance." You can earn up to £1,000 of gross trading income in a tax year before you're required to register for Self Assessment. This is deliberately generous so hobbyists testing the water aren't buried in paperwork. Cross that threshold and you need to register with HMRC and file a Self Assessment tax return.
Registering as a sole trader is free. It's an online registration with HMRC, and you'll then report your profits once a year. You keep your own records of income and expenses — no public filing, no accountant strictly required (though many find one worth it).
VAT is a separate question from company structure. You only have to register for VAT once your taxable turnover crosses the registration threshold (£90,000 at the time of writing), and that applies whether you're a sole trader or a limited company. Being a sole trader doesn't exempt you from VAT, and being a Ltd doesn't force you into it early.
When a Ltd company starts to make sense in the UK
A private limited company (Ltd) is a separate legal entity from you. That separation is the whole point, and it's why sellers eventually incorporate:
Limited liability. If the business runs into debt or gets sued, your personal assets — your house, your savings — are generally protected, because the company is legally distinct from you. As a sole trader there's no such wall; your business debts are your debts.
Tax efficiency at higher profits. Above a certain profit level, the mix of corporation tax plus taking money as a modest salary and dividends can be more efficient than paying income tax on everything as a sole trader. Where that crossover sits depends on current rates and how much you draw out — this is exactly the sort of thing to model with an accountant rather than guess.
Credibility and access. Some suppliers, wholesalers, and B2B customers prefer dealing with a registered company. It can also make it easier to bring in a co-founder or raise money later.
The trade-off: a Ltd company means filing annual accounts and a confirmation statement at Companies House (some of which is public), running payroll or dividend paperwork, and generally more admin. For a brand-new store doing a handful of sales a month, that overhead usually isn't worth it yet. Start as a sole trader, and incorporate when the liability exposure or the tax maths genuinely justifies it.
Selling online in the US
The US picture rhymes with the UK's but with different names and one important wrinkle: business formation happens at the state level, not federally. There's no single national "register a business" button — you form your entity in a state (usually the one you live and operate in).
By default, if you just start selling as an individual, you are a sole proprietor. Like a UK sole trader, there's no entity to create — you report business income on your personal tax return (a Schedule C attached to your 1040 for a typical single-owner operation). You can start today with nothing filed. Many sellers do exactly this to validate an idea before spending a cent on formation.
The most common next step up is the LLC (Limited Liability Company). It's popular precisely because it's a middle ground: the liability protection of a company with far less rigidity than a full corporation.
Liability and tax reasons to form an LLC
Liability protection. This is the headline reason. An LLC creates a legal separation between you and the business, so — if you run it properly and keep finances separate — a lawsuit or business debt generally can't reach your personal assets. A sole proprietor has no such shield.
Flexible taxation. By default a single-member LLC is a "disregarded entity," meaning it's taxed just like a sole proprietorship — the income flows onto your personal return, no separate corporate tax. So a basic LLC often doesn't change your tax bill much; it mainly adds the liability wall. As you grow, an LLC can elect to be taxed differently (for example as an S-corp) to reduce self-employment tax — again, a conversation for a CPA.
Professional footing. A registered LLC, an EIN (the business tax ID you can get free from the IRS), and a business bank account make it easier to work with wholesalers, payment providers, and marketplaces.
The catch is that state-level nature. Each state sets its own formation fee and, often, an annual fee or franchise tax to keep the LLC in good standing — anywhere from modest to a few hundred dollars a year depending on the state. So an LLC isn't free to maintain, which is another reason not to rush it before you have revenue to protect.
A simple way to decide (either country)
Strip away the jargon and it comes down to two questions:
How much could go wrong? If you're selling low-risk products in small volumes, your liability exposure is low and a sole trader / sole proprietor setup is usually fine. If you're selling anything that could physically harm someone (cosmetics, supplements, electricals, children's products), carrying meaningful stock, or signing supplier contracts, the liability shield of a Ltd/LLC becomes worth its cost sooner.
How much are you making? Below the trading allowance in the UK or a modest hobby income in the US, keep it simple. As profits climb, the tax and liability advantages of incorporating start to outweigh the admin — that's your cue to talk to a professional about switching.
The reassuring part: none of this blocks you from starting. You can open your store, make your first sales as an individual, and formalise the moment the numbers say it's time. Nobody hands out prizes for incorporating before you've proven anyone wants to buy.
What to sort out before your first sale (that isn't a company)
The things that do matter from day one are usually cheaper and quicker than company formation:
A way to get paid. A payment processor or checkout that works for individuals as well as companies.
Honest policies. Clear returns, delivery, and privacy information. Consumer law applies to sole traders too — building that trust into your checkout matters, as we cover in designing trust into your checkout.
Basic record-keeping. Track income and expenses from sale one, whichever structure you choose. It makes the eventual tax return — and any future decision to incorporate — painless.
Tax settings for where you sell. If you sell across borders, get your tax handling right early; our guide to tax for international sales is a useful primer.
Notice that "spend hundreds forming a company" isn't on that list. The genuine cost of starting is far lower than most beginners fear — you can even start an online store for free and see how long it really takes to build before you commit to any formal structure. Keeping fixed costs low matters most in the early days, which is why Dirora has a genuine free plan, charges no transaction fees on any plan — just standard card processing — with only a small platform fee on the lower tiers that falls to 0% as you scale — the platform shouldn't be another reason to delay launching while you sort out paperwork you may not even need yet.
The verdict
No, you don't need an LLC or a Ltd company to sell online. In the UK, start as a sole trader and tell HMRC once you pass the trading allowance; form a Ltd when limited liability or tax efficiency at higher profits justifies the admin. In the US, start as a sole proprietor and form an LLC — in your state — when you want the liability shield or your growth makes the tax flexibility worthwhile. In both countries the smart move is the same: launch as an individual, keep clean records, and formalise when the business has earned it. Then check the specifics with an accountant, because your circumstances are yours alone.
Frequently asked questions
Can I sell online without registering a business at all?
Yes. In both the UK and US you can legally sell as an individual — a sole trader or sole proprietor — with no company registered. In the UK you must tell HMRC once your trading income passes the £1,000 trading allowance; in the US you report income on your personal tax return. You can start with nothing formally set up.
When should I form a Ltd company in the UK?
Consider a Ltd company when you want limited liability protecting your personal assets, when profits reach a level where corporation tax plus salary and dividends is more efficient than sole-trader income tax, or when suppliers and B2B customers expect a registered company. Below that, a sole trader is simpler and cheaper to run.
When should I form an LLC in the US?
Form an LLC mainly when you want liability protection separating your personal assets from the business, or when growth makes flexible taxation (such as an S-corp election) worthwhile. A basic single-member LLC is taxed like a sole proprietorship by default, so it often adds protection rather than changing your tax bill. Remember LLCs are formed and maintained at the state level, usually with annual fees.
Does having a company make my store look more legitimate?
It can help with suppliers, wholesalers, and some B2B buyers, but for most direct-to-consumer online stores, trust comes from clear policies, honest delivery information, secure checkout, and good reviews — not from whether you're incorporated. Customers rarely check your legal structure before buying.
