Read the latest magazine Industry News Next Year’s Rollout for IR35 Private Sector Reform Questioned 12 April 2019 DESPITE A number of controversies since IR35 reforms were first introduced for contractors and freelancers working within the public sector, HMRC is pushing ahead with plans to roll-out the reforms to cover contractors and subcontractors working within the private sector in 2020. In light of this, tax preparation specialist David Redfern, Managing Director of DSR Tax Claims Ltd, has questioned whether the reforms are currently fit for rollout to the private sector due to the issues experienced by public sector contractors. IR35, otherwise known as Off-Payroll Working Regulation, was introduced in 2000 in order to crack down on tax avoidance through disguised employment. Reforms were introduced in 2017, initially aimed at contractors working on public sector contracts. These shifted the responsibility for checking employment status from the contractor to the business utilising the contractor. IR35 Reform Debate Plans to roll the reforms out further to cover the private sector are due to go ahead in 2020, with the government claiming that this will close a tax avoidance loophole which they estimate will cost public finances £1.3 billion by 2024. However, a debate in parliament on IR35 reform on 4th April 2019 heard MPs discuss “anxieties about the roll-out in the private sector”, with particular concern raised because “HMRC guidance and tools are far from 100% effective.” The debate in parliament heard MPs air a number of concerns which had been raised by their constituents, including the impact on businesses to recruit contractors. Redfern stated, “Through the public sector rollout of the reforms, large numbers of contractors have chosen to no longer work on public sector contracts due to the concerns surrounding HMRC’s pursuit of those they believe fall foul of the reforms. “Whilst public consciousness often focuses on higher-paid contractors, flying under the radar are the large number of lower-paid contractors, including many working within the NHS as nurses or nursing assistants, who now find themselves caught up in the net of IR35.” David Redfern, Managing Director of DSR Tax Claims Ltd Issues surrounding HMRC’s Check Employment Status for Tax (CEST) tool came in for particular criticism in parliament, with the tool being described as “flawed”. Redfern commented, “CEST is still being flagged as a huge issue with regard to rolling out IR35, in particular with its assumption of ‘mutuality of obligation’. Many contractors, especially those in lower-paid contracting roles, will know that not only can they cancel their shift at any time, so can the employer with no expectation that there will be available work at any point in the future and yet CEST has that mutuality of obligation built into its assumptions. “As the reform shifts the onus of determining whether an individual comes within IR35 from the individual to the business, many contractors will find themselves caught up in IR35 due to an inaccurate assessment using CEST. And yet criticisms of this tool go back at least a year, if not longer.” Redfern added that due to these concerns, private sector businesses may choose instead to move their business to large outsourcing organisations which would remove flexibility within the workforce while at the same time increasing costs. Redfern concluded, “Contractors have legitimate concerns that their efforts to remain on the right side of regulations could ultimately land them with huge tax bills in the future. In addition, as HMRC is currently losing around 50% of the cases they bring against contractors, this suggests that the IR35 reforms need further attention before rolling out. It would be far better to delay the roll-out beyond 2020 than rush it through and cause further confusion.” Previous article Moderate Growth in UK Construction Output Amid Brexit UncertaintyNext article £7m Fines For Construction Fit-Out Cartel Companies Share article You may also like View all News Industry News +2 20 March 2026 RA Issues Revised Safety Guidance on Rooflight Covers Awards and Events +3 20 March 2026 The Great British Slate Off Returns for 2026 Green Roofs +3 20 March 2026 Swansea Joins Global Network of Biophilic Cities Featured Solutions +3 19 March 2026 Flush Fitting Rooflights by Clement Sign Up to Roofing Today Stay up to date with all of the latest news from Roofing Today by signing up to our weekly Bulletins… Sign Up Today Get in Touch Check out the latest issue 123 March-April 2026 View Now Past Issues Get in Touch
