IR35 lawyers

Lawspeed’s specialism in contracts and employment status has meant we have been well placed to help our clients. As a result in 1999 we developed the very first IR35 contracts used by hirers, agencies and contractors alike. These have stood the test of time and remain fully valid today. As an example of the successful approach used, in 2002 the contract terms drafted by Lawspeed helped the contractor to succeed in the very first reported IR35 challenge by HMRC. See the Special Commissioners case LimeIT v Justin 2002. Our approach also enabled us to evolve the first ever IR35 tax expenses insurance package.

Since 2000, thousands of businesses have relied on our IR35 legal advice and auto updated contract templates.
