United Kingdom reporting cycles and business-day rules
UK business-day cycles run against HMRC's PAYE Real Time Information schedule (returns due by the 19th, electronic payment by the 22nd of the following month) and BACS three-day settlement (input Day 1, processed Day 2, credited Day 3). The Bank of England's CHAPS service settles same-day until 3:30pm London for a 4pm cutoff. Companies House filings use a working-day clock under the Companies Act 2006. Court deadlines under CPR 2.8 count clear days, excluding both the start and end day where business days are specified.
