1 min readBlockingBank of England taxonomy 2.2.0Updated 11 November 2026

Own funds and 2 other templates: values must agree (IR.23.01, IR.23.02, IR.23.03, Bank of England rule IR_bv0640_02)

A blocking check on the own funds (IR.23.01), detailed information by tiers on own funds (IR.23.02) and annual movements on own funds (IR.23.03) templates, in the annual group (ARG) return.

The rule in plain words

The item "Balance carried forward" reported in Annual movements on own funds (IR.23.03.04.04) should be equal to the sum of balance brought forward and the Increase reduced by Reduction

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark IR.23.03 as reported.
