The maximum approvable benefit is the highest level of pension and tax‑free lump sum that a pre‑6 April 2006 Inland Revenue/HMRC approved occupational pension scheme could provide to a member while retaining tax approval. It is not a statutory term; it reflected HMRC approval practice and guidance for approved schemes under ICTA 1988. In defined benefit schemes this commonly meant a pension capped at two‑thirds of final remuneration after up to 40 years’ service, subject to the earnings cap and commutation limits for tax‑free cash.
In the UK (England & Wales, Scotland and Northern Ireland) the concept became obsolete on A‑Day (6 April 2006), when the Finance Act 2004 registered pension scheme regime replaced approval limits with the annual allowance and, formerly, the lifetime allowance, alongside new lump‑sum rules. The expression may still appear in legacy scheme rules and historic calculations and remains relevant when reviewing pre‑A‑Day accrual, protected tax‑free cash and transfers.
In Ireland, HMRC does not apply. A comparable, still‑current concept is the Irish Revenue Commissioners’ “Revenue maximum benefits” for approved occupational pension schemes, which cap pension and lump sums by reference to final remuneration and service. Usage is broadly consistent in practice.
