HMRC has changed the details provided on the Employer Payment booklets (P30BC) and letters issued about paying PAYE electronically (P30B) and paying PAYE once a year using a payslip (P30B Annual). Going forward the booklets will no longer include the name, address or phone details of the issuing office. This will apply for:
the remaining months of the 2013-14 tax year;
the whole of the 2014-15 tax year; and
all future years.
