At the beginning of April 2025, we will be retiring the 2021 taxonomies suite.
This means that from April 2025, we will reject any accounts submissions that use the 2021 taxonomy entry points.
In April 2025, we will also be releasing the 2025 taxonomies suite.
From then, Companies House will only accept accounts submissions using the following taxonomies suites:
2025, 2024, 2023 and 2022.
This will align with the taxonomies accepted by HMRC.
