Filing LLP Accounts with Companies House

@AdamsWinter fully supports filing LLP (Limited Liability Partnership) annual accounts with Companies House electronically. This guide explains how LLP filing works and how to get started.

How LLPs Differ from Limited Companies

LLPs are taxed as partnerships, not corporations. This means:

No CT600 — LLPs do not file corporation tax returns. Each member reports their share of profits on their individual Self Assessment tax return instead.
Accounts only — LLPs file annual accounts with Companies House, but there is no HMRC CT600 submission.
Members, not directors — LLPs have designated members rather than directors.

ℹ If you currently file paper accounts with Companies House, @AdamsWinter lets you switch to electronic filing. It is faster and you get instant confirmation.

What You Will Need

Before you start, make sure you have:

Your company number — This starts with OC (England/Wales), SO (Scotland), or NC (Northern Ireland)
Your profit and loss figures — Turnover, cost of sales, expenses
Your balance sheet figures — Assets, liabilities, and members equity
Your Companies House authentication code — A 6-character code sent to your registered office. See our auth code guide if you need to request one.

Getting Started

Sign up at adamswinter.com and create your account
Search for your company using your OC/SO/NC company number
@AdamsWinter automatically detects your LLP and sets you up for accounts-only filing — the CT600 option is disabled because LLPs do not need it
Select your company type — Trading, Property, or Dormant (this determines which P&L fields appear)

ℹ @AdamsWinter recognises LLPs automatically from your company number. You do not need to configure anything — the accounts-only filing path is selected for you.

Filing Your Accounts

Profit and Loss

Enter your income and expenditure figures. The fields you see depend on your company type:

Trading LLPs — Turnover, cost of raw materials, staff costs, depreciation, and other charges
Property LLPs — Property rental income, associated costs, and expenses

Balance Sheet

Enter your assets, liabilities, and equity figures. @AdamsWinter automatically fetches your prior year figures from Companies House where available.

ℹ The "Called up share capital not paid" field does not appear for LLPs — it only applies to limited companies with share capital.

Review and Submit

Once you have entered your figures:

Click Preview to review your generated accounts
@AdamsWinter creates your accounts in micro-entity iXBRL format — the format Companies House requires for electronic filing
Click Submit Accounts and enter your Companies House authentication code
Your accounts are filed directly with Companies House

You will receive confirmation once Companies House accepts your filing.

Dissolved or Struck-Off LLPs

If your LLP has been dissolved or struck off, you will not be able to add it to @AdamsWinter. @AdamsWinter looks up companies from the live Companies House register, and dissolved companies do not appear as active entities — so the search will return no results, or the company will be blocked from being added.

⚠ @AdamsWinter only supports active companies. A dissolved or struck-off LLP cannot be added until it has been reinstated on the Companies House register.

If your LLP is being reinstated

Once your LLP has been successfully reinstated and shows as active on the Companies House register, you will be able to add it to @AdamsWinter and file your accounts electronically as normal.

Reinstatement is handled through Companies House (or the courts, depending on how long the company has been dissolved). You can check the status of your LLP at any time on the Companies House register.

Filing paper accounts while dissolved

@AdamsWinter generates iXBRL accounts for electronic submission to Companies House — it is not designed to produce accounts for manual/paper filing. If you need to file paper accounts for a dissolved LLP before reinstatement is complete, you will need to use a different tool or engage an accountant to prepare accounts in the correct format.

Common Questions

Do I need to file a CT600?

No. LLPs are taxed as partnerships, so there is no corporation tax return to file. Each member reports their share of profits on their personal Self Assessment tax return (SA800/SA104).

Can @AdamsWinter file my members Self Assessment returns?

No. @AdamsWinter handles LLP accounts filing with Companies House only. Members need to file their Self Assessment returns separately, either directly with HMRC or through accounting software.

What format are the accounts?

@AdamsWinter generates micro-entity iXBRL accounts — the standard electronic format required by Companies House. This is the same format used by all electronic filing software.

I currently file paper accounts — can I switch?

Yes. @AdamsWinter files your accounts electronically with Companies House. It is quicker than posting paper accounts and you get instant confirmation of receipt.

How do I get a Companies House authentication code?

Visit gov.uk/file-your-company-annual-accounts, click Request an authentication code, and enter your company number. The code is posted to your registered office within 5 working days. See our full auth code guide for more details.
