The Association of Independent Professionals and the Self-Employed (IPSE) is a British not-for-profit organisation. It was established in 1999 as the Professional Contractors Group, a protest group against the IR35 tax statute. Later, it expanded its responsibilities to cover the wider interests of freelance consultants and contractors as a representative body for freelancing in the UK. It is a company limited by guarantee, owned and run by its members. In September 2014 the PCG changed its name to IPSE, and increased its constituency to the entirety of Britain's 4.3 million freelance and self-employed workers.
