At the High Court this week, a body representing the UK's self-employed IT contractors have been arguing that the government's IR35 tax rules are illegal.
IR35 came into force in April 2000, and increases the tax liabilities of a consultant's personal services company by taxing turnover as income. Lawyers for The Professional Contractors Group (PCG) have argued that this unfairly penalises small IT services providers because large organisations aren't affected, making IR35 in effect an illegal state aid for big companies.
The government claims that IR35 was brought in to stop the "Friday to Monday" syndrome -- where IT workers resign their salaried job only to carry on doing the same work, but as a self-employed contractor.
According to the PCG, IR35 will drive thousands of the UK's high-tech workers overseas.

Closing the loopholes in IR35
The laws to discourage tax dodging, should not go so far that they make it better for people to leave the country and work offshore. Guy Kewney isn't sure whether abandoning IR35 altogether is the answer -- but it certainly needs some serious tidying up. For complete business coverage, see ZDNet UK's Enterprise Channel.
