Filleted, abridged and micro-entity accounts: why there is no profit in them

You are buying a small British company. You do the sensible thing: you look up its accounts on the public register. They are there, filed on time, nothing overdue.

You open them. There is a balance sheet. There are some notes.

There is no profit figure anywhere.

Nothing has gone wrong. Nobody has hidden anything. That is what the law allows.

The word for it is "filleted"

This is the register's own word, not ours. Companies that choose not to file their director's report and profit and loss account are said to be filing filleted accounts — in every case they must still file at least the balance sheet and its notes.

Like a fish. The bones taken out, the shape left behind.

Who is allowed to do this

Most small businesses you are likely to buy.

Small companies do not have to deliver a copy of the directors' report or the profit and loss account to Companies House. If they leave it out, they must say so on the balance sheet. That line is easy to miss, and it is the whole story.

Micro-entities — the smallest tier — may send only a balance sheet, with less information in it.

Dormant companies do not need to include a profit and loss account at all.

What this means when you are buying

Filed accounts and useful accounts are two different things.

A shop turning over a few hundred thousand can legally show the public a single page describing what it owned and owed on one day of the year, and nothing at all about whether it made money.

So when a seller says "the accounts are on the register, go and look" — that may be perfectly true and still tell you nothing about trading.

What you can still learn from a filleted set

Quite a lot. Look at four things.

1. Which type was filed. The register labels it: full, small, micro-entity, dormant. "Dormant" on a business that is supposedly trading is a question that answers itself.
2. Whether filings are overdue. Late accounts are one of the earliest visible signs that something is wrong inside.
3. The trend across years. Even a bare balance sheet, read across three or four years, shows whether the business is accumulating or shrinking.
4. The note saying what was left out. If they filleted, it must say so.

How to look yourself, in five minutes

Go to find-and-update.company-information.service.gov.uk, find the company, open filing history. Free, no account.

Then ask the seller — in writing — for the full accounts including the profit and loss, the ones prepared for the members rather than for the public. Those exist. They were prepared. They simply were not filed.

A seller who will not hand those over has told you something, and it did not cost you anything to find out.

🔴 What changes in 2028, and what does not

The rule is being tightened. From April 2028, small companies and micro-entities must file profit and loss accounts like everyone else. The option to file abridged accounts is being removed at the same time.

But read the next part carefully, because it is the part that concerns you.

Those companies will be able to opt out of publishing that information on the public register. Where they do, Companies House, law enforcement and the tax authority will still see it.

The state will have the numbers. A buyer looking at the public register will not.

So the gap narrows. For you, it does not close.

⚠️ Two things to keep in mind. This date has already moved once — it was April 2027 before being pushed back. And the government has said the details of how a company opts out will be confirmed later. Check the position on the day you need it.

What it costs not to look

Nothing on the day. Later, the cost is simple: you paid for a profit you never actually saw, on the strength of a document that was never required to contain it.

If you are not in the UK

Small-company filing exemptions exist across Europe and beyond, under different names. The question that travels: what is this company legally required to publish, and what is it allowed to leave out? Ask that before you treat filed accounts as evidence of trading.
