Statutory Standards and Frequently Asked Questions
Off-payroll working rules still sit with the end client for medium and large private-sector hirers of Cost Engineer contractors nationwide. A Status Determination Statement should precede start date, and PAYE or umbrella treatment usually follows an inside finding. Outside IR35 work is invoiced to a limited company and tax planning stays with the limited company. Regional pay still follows UK-wide rate parity. Use HMRC guidance and, where needed, a status review rather than the vacancy wording alone. Filter the board above by IR35 to see how the mix lands in Data and Analytics.
