Grandfathered Corresponding Acceptance describes a transitional protection that lets UK taxpayers continue to receive
tax relief, after 6 April 2006 (A‑Day), on contributions to certain overseas pension schemes that previously had HMRC “corresponding acceptance”. Where both the individual and the employer obtained UK tax relief on such contributions in the 2005/06 tax year, relief could carry on on terms broadly similar to
migrant member relief (MMR).
The expression is not a defined statutory term. It is used in HMRC pensions guidance to explain how the Finance Act 2004 regime and its transitional provisions preserved pre‑A‑Day relief in narrowly defined cases. In practice, relief is usually limited to the same employment and the same overseas scheme, subject to MMR‑style limits and conditions, and depends on evidence that both employee and employer relief was actually claimed in 2005/06.
This usage is consistent across England & Wales, Scotland and Northern Ireland (UK pensions tax is a UK‑wide regime). It is not generally used in the Republic of Ireland, which has separate pensions tax rules. Practitioners should verify eligibility, historic payroll and self‑assessment records, and any interaction with recognised overseas pension schemes (ROPS) requirements.
