Statutory Standards and Frequently Asked Questions
Birmingham does not create a special IR35 code for Mobile Developer work. The client SDS should name the Birmingham workplace and delivery model. An inside finding on a Birmingham Mobile Developer brief typically deducts tax at source, while outside IR35 Mobile Developer work in Birmingham is billed by a PSC. Local pay sits on major-city rate parity, so a higher Birmingham headline rate can still be inside. Commuting into Birmingham does not, by itself, prove substitution or lack of control. Read the Mobile Developer Birmingham contract for workplace, hours, and equipment clauses.
