2 min readBlockingEIOPA taxonomy 2.10.0Updated 11 November 2026

The "Total" value reported in Own funds must be equal to the sum of "Tier 2" and "Tier 3" (S.23.01, EIOPA rule BV81)

A blocking check on the own funds template (S.23.01), in the quarterly solo (QRS), quarterly group (QRG), annual solo (ARS) and annual group (ARG) returns.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

The "Total" value reported in Own funds (S.23.01) must be equal to the sum of "Tier 2" and "Tier 3"

EIOPA writes it out as separate checks, one for each table or return it covers. Line4 Check runs four of them (BV81-1 to BV81-4), and a failure names the one that failed.

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 S.23.01 as reported.
