An anonymous reader shares a report: The vast majority of UK government IT projects are suffering delays due to freelancers quitting over the IR35 tax clampdown, according to a survey of contractors. Of 405 IT freelancers surveyed by Contractor Calculator, 79 per cent said the projects they have been working on were delayed as a result of contractors leaving. In April, the government shifted responsibility for compliance with the IR35 legislation from the individual contractor to the public body or recruitment agency. The Treasury says it hopes to raise $240m for 2017/18 by bringing public sector contractors within the scope of the legislation. However, the overall number of freelancers leaving as a result of the changes is lower than previously thought, with 48 per cent jumping ship. In previous surveys more than 80 per cent had threatened to walk once the changes came into force. Half of the contractors who decided to stay managed to find a way of working outside the IR35 changes, with a further 13 per cent working within the scope of IR35 but negotiating a rate increase. The rest seemingly took the changes on the chin.
