Guidance on completing Form OS IN01

We have noticed that customers are having problems completing form OS IN01 which is causing a significant proportion of forms to be rejected at least once. The information below is aimed at helping you get it right first time and provides guidance on the most common reasons for the forms being rejected. Please read this information before you send your form OS IN01 to Companies House:

• Section B5 - Accounting requirements (not required to be completed by EEA companies)

  • The period shown for which the company is required to prepare accounts by parent law must cover a 12 month period (e.g. from 01/04 to 31/03).
  • The number of months allowed for disclosure under parent law must be provided.

• Section B6 - certification of translation of accounts

  If the company is required to file accounts disclosed under parent law with Form OSIN01 and the accounts are in a language other than English, an English translation is required.

  • A certified translation into English must be authenticated by a secretary, director, permanent representative, administrator, administrative receiver, receiver manager, receiver or liquidator.
