HMRC inspectors, in common with all HMRC staff below the senior civil service, are subject to a single pay and appraisal system which includes recognition bonuses for exceptional performance, top performance bonuses for those attaining the top marking as part of their annual appraisal, consolidated pay awards, and promotion on merit.
HMRC aim to reply to 80 per cent. of all correspondence within 15 working days, and 95 per cent. within 40 days. There is no separate target relating specifically to enquiries from Members of Parliament. Hon. Members can use the dedicated hotlines that HMRC have in place for specific issues, such as the ‘MP hotline’ for telephone queries about constituents' tax credits claims.
