Choosing a structure is mostly a decision about who is liable

One decision, two questions

Ask what legal form a small business should take and the conversation goes almost immediately to tax, because tax is the part people have heard arguments about. That is the second question. The first is who has to pay if something goes badly wrong, and it should be settled first because it is much harder to fix retrospectively.

The forms available differ by country, as do their names, so this is deliberately about the underlying mechanics rather than any particular option. What is consistent almost everywhere is that the choices sit on a spectrum, running from you and the business being the same legal person to you and the business being two.

At one end, the business is simply you

Trading in your own name as an individual is the default in most systems, and there is nothing amateur about it. Enormous numbers of skilled people spend entire careers this way. It is cheap, it’s quick, and the administrative load is the lightest available.

What it means, precisely, is that the business does not exist as a separate thing. Its debts are your debts. A judgement against the business is a judgement against you, and it can reach whatever you own. There is no line between the money in the business account and the money in your pocket, because legally there is one pocket.

For a great deal of work, that exposure is theoretical. If the worst realistic outcome of a mistake is refunding a fee and losing a client, unlimited liability is a risk you are already carrying comfortably.

At the other end, the business is a separate person

Incorporated forms create an entity that owns its own assets, signs its own contracts and owes its own debts. You own it, you probably run it, but you’re not it. If it fails owing money, the general position is that creditors reach the entity and stop there.

That protection is real and it’s also narrower than people assume. It falls away where you have personally guaranteed a debt, which lenders and landlords routinely require of a small company. It does not cover your own negligence or wrongdoing. And it does nothing at all about the money you have already put in, which is simply gone if the thing folds.

The trade is administrative. A separate legal person has to file its own paperwork, keep its own accounts, and in most places make some of that information public. The cost is not enormous but it is permanent, and it arrives whether or not the year was any good.

Tax treatment is the second question, and it moves

How each form is taxed is genuinely different, and in some circumstances the difference is large enough to justify the choice on its own. But it changes. Governments adjust the relative treatment of employment, self-employment and small company ownership regularly, sometimes deliberately to close a gap that had opened up.

That is the argument against choosing a structure primarily on a tax comparison you read somewhere. The comparison was true for one country in one year at one level of income, and any of those three can move underneath you. An accountant who works in your jurisdiction can run the arithmetic on your actual numbers, which is the only version of the comparison that means anything.

Perception and privacy are minor considerations that occasionally are not

Some clients will not engage an individual, usually for reasons rooted in their own procurement rules rather than any judgement about you. In sectors where that is common, incorporating is a sales decision more than a legal one, and it is a perfectly legitimate reason.

Running the other way, incorporated forms usually publish something — a registered address, the names behind it, sometimes a summary of the accounts. For most people that’s a non-issue. For anybody who works from home and has reason to keep that address private, it is worth knowing before rather than after.

The decision is reversible, at a price

You can change form later, and plenty of people do, typically when the work gets bigger or riskier than it was. Moving a going concern from one legal person to another is a real transaction with real consequences, and it is the kind of thing that wants advice rather than a form filled in on a Sunday.

So the sensible way to hold the question is this. Start with the lightest structure that adequately covers the worst realistic outcome of your work going wrong, and revisit when either the risk or the income changes materially. Not annually. When something actually changes.
