This article explains how to link sole traders and individuals within the MTD IT module demonstrating how the individuals are linked to multiple sole trader business.
Linking is a mandatory requirement when using the Bookkeeping module alongside the MTD IT module to pull in the relevant information to ease your submissions.
Before you start:
- Add client clients to the MTD IT module.
- Ensure if the Sole trader clients have already added in My Admin section.
- Client Authorisation process is completed.
This feature allows you to link multiple individuals across multiple sole trader businesses. There are two scenarios to be aware of:
- Assigning multiple individuals across different sole trader businesses.
- Assigning one individual across multiple sole trader businesses.

Important Note: When a sole trader record is linked to an individual record, both records will share one licence. Please be aware that two separate records will still appear in 365, My Admin, and Practice Management. This is intentional and does not indicate a duplication or error. The records remain separate because the sole trader and the individual are legally distinct entities even though they share a single licence. |
