Filing & Returns

Required documents for filing

6 min read

Preparation is key to a smooth filing experience. Gathering the correct documents beforehand will save you time and prevent errors during the WeFile wizard.

Company Identifiers

You will need your 8-digit Company Registration Number (CRN) issued by Companies House, and your 10-digit Unique Taxpayer Reference (UTR) issued by HMRC. Do not confuse the UTR with a VAT registration number or PAYE reference.

Financial Data

Have your final, reconciled Profit & Loss figures and Balance Sheet ready. Specifically, you need: total sales revenue excluding VAT, a breakdown of allowable business expenses, your exact bank balance on the final day of the accounting period, the value of any physical assets, and the exact amounts owed to you (debtors) and owed by you (creditors, including estimated tax).

Authentication

To authorise the submission, you will need your Companies House WebFiling Authentication Code (a 6-character alphanumeric code sent to your registered office) and your 12-digit HMRC Government Gateway ID and password.
