The latest GMS final seniority figures released by the NHS Information Centre are £92,955 for England and £79,096 for Wales.
The figures for 2008/9 are up on the previous figures for 2007/8 which were £90,375 for England and £78,938 for Wales.
The final seniority factors are calculated once data from GP tax returns has been collected and the average superannuable income from GPs is known.
They are published by the Technical Steering Committee, which includes representatives from the GPC, NHS Employers and the health departments for England and Wales.
Mike Gilbert, a consultant at RMT accountants said GPs payments for previous years would be adjusted in the light of the new figures. ‘They don't tend to make much noticeable difference but taken with everything else they're significant. There will be some adjustments for those GPs who are eligible.'
Seniority factor payments were introduced as part of the GMS contract in 2004 and were designed to reward GPs' experience.
