Contractors and freelancers had until the end of June to register for the Contractor Loans Settlement Opportunity (CLSO). Launched in July 2014, the CLSO gives those who used Contractor Loans Schemes before April 2011 the opportunity to resolve their tax dispute under this campaign. Those who have used these schemes and fail to use the CLSO risk having to pay additional tax charges and penalties, as well as potential litigation costs should their case reach the Tax Tribunal.
