The absence of a clear definition of self-employment, and limited access to relevant personal information for each contractor, can make it challenging for hiring organisations to make status determinations confidently. Hiring organisations can face significant financial consequences if they incorrectly assess someone as self-employed, and this risk may affect their determinations. Workers can challenge decisions with the hiring organisation, but they have no independent route to appeal. The hirer must respond formally to an appeal from a contractor within 45 days. However, if they do not change the status, the worker has no further recourse other than to seek a refund from HMRC by completing their self-assessment return on a self-employed basis. It is unclear how effectively these routes operate in practice and the extent to which they are used, because HMRC does not monitor this. Recommendation: HMRC should ensure there is a fast and independent process for contractors to resolve disputes over status determinations. As part of this, it should assess the extent to which workers are using existing appeals routes, and how well they are working. Show less

The complexity of the rules, and the perceived risk to hiring organisations of failing to comply with them, may lead to changes in behaviour by both workers and hirers. In some cases, contractors have reported that their last clients had stopped all use of PSCs, while some contractors have increased their rates or avoided work if it is within scope of the IR35 rules. Such behavioural impacts 6 Lessons from implementing IR35 reforms could have knock-on consequences for workers and labour markets, such as loss of work or ability to work flexibly. HMRC has not carried out research into these types of wider impacts, and it is not convinced by evidence provided by others even where this indicates there may be significant issues. HMRC is also too dismissive where a significant minority of people and businesses report being adversely affected. Recommendation: HMRC should conduct and publish specific research into the impacts of the IR35 reforms on contractors and labour markets, to check it is being applied as intended and not adversely affecting employment opportunities.

Issues in UK supply chains have been widely reported in recent months, for example in fuel and groceries. It is unclear to what extent the IR35 changes may have contributed to these by affecting hiring practices or decisions by contractors in key parts of the workforce. Particular concerns around difficulties in implementing the rules have also been raised by contractors in the broadcasting and IT sectors, and these issues may be compounded in areas that have seen changes to more flexible and ad-hoc working practices in recent years. We do not have confidence that HMRC is identifying which sectors may be disproportionately affected, nor that it is working proactively with affected sectors to understand what issues they are facing and how these might be addressed. Recommendation: HMRC should proactively identify and work with sectors that have been particularly affected to understand the challenges, establish how to address them and make it easier to comply. HMRC should write to us with an update in six months with the outcome of this public engagement. Show less

HMRC states that the IR35 reforms increased tax revenues by increasing the number of people employed for tax purposes, but it is unclear to what extent employment patterns have been affected by other factors. EU Exit, the COVID-19 pandemic and other changes in government to reduce use of contractors mean HMRC cannot be certain to what extent the increase is due to the reforms. There is also not a complete picture of the costs of the reforms against which the benefits could be compared. The government introduced the reforms because it considered it too costly for HMRC to oversee an effective compliance regime with each individual PSC. HMRC also concluded that hiring organisations could administer the rules for less cost than PSCs doing it themselves. However, HMRC’s modelling of the cost to hiring organisations works out at just £35 a year per PSC, based on a theoretical minimum needed to comply. HMRC does not know what it actually costs all parts of the labour supply chain to administer the reforms in practice. Recommendation: In light of actual experience, HMRC should produce and present to Parliament a cost-benefit analysis of the reforms that reflects the actual costs of compliance to HMRC itself, hiring organisations, workers, and others in the supply chain.

The IR35 rules do not work well with the realities Lessons from implementing IR35 reforms 7 of contracting, both in determining workers’ tax status and in resolving issues when mistakes have been made. For example, hiring organisations are now responsible for assessing tax status, but may not have access to all the information necessary to assess the totality of a worker’s income and other work. While HMRC interprets IR35 as applying to individual engagements, recent court cases have focused more on a worker’s business in the round. The legal framework and realities of contracting also make it difficult to correct errors if HMRC later finds a hiring organisation to be non-compliant. Hirers often lack the data on affected workers that HMRC would need to work out their actual tax position. Furthermore, the legislative framework does not allow HMRC to offset liabilities against taxes already paid, meaning it collects tax twice on the same income and workers become able to reclaim all the tax they paid. Ironically, the public sector may end up paying all the tax on workers it incorrectly assessed as self-employed. This position does not look sustainable and risks being more costly to all parties the longer it goes on. Recommendation: HMRC should review how the system is working and whether it can be made more efficient and effective. In particular, it should develop solutions to address problems with how the IR35 rules work in practice, including ensuring that: • HMRC has the data it needs to accurately reflect each worker’s tax position in cases of non-compliance; and • HMRC does not end up taxing the same income twice, or unwittingly contributing to workers not paying their fair share in tax. 8 Lessons from implementing IR35 reforms 1 How the IR35 reforms work in practice Show less

HMRC suggested that smaller organisations may be better placed to comply, if key personnel involved in compliance are closer to the hiring parts of the organisation.11 However, HMRC also acknowledged that its compliance efforts had mainly been focused on government departments so far, after identifying a higher chance of compliance problems in its early risk assessments, compared with other public bodies.12 The ability of workers to appeal incorrect status determinations Show less

There is no route for individuals to appeal past this point.15 Show less

In particular, recent court rulings suggest that it may be necessary to consider a contractors’ work portfolio and income in the round, rather than on an engagement-by-engagement basis. If so, it is hard to see how a hiring organisation can realistically have all the information it would need to do this better than the workers themselves.22 Show less

In particular, the hirer would not normally collect a worker’s National Insurance number if they are self-employed. However, if HMRC later judges that the worker should have been treated as employed, it needs the National Insurance number to identify their actual tax position. This means that when HMRC finds workers have been misclassified, it normally lacks the data to accurately calculate the additional taxes owed.23 Show less

This means that HMRC collects tax twice on the same income, and that workers become able to reclaim all the taxes they already paid without needing to compensate the hiring organisation.25 Ironically, the public sector may therefore end up paying all the tax on workers it incorrectly assessed as self-employed. HMRC does not know how much this is happening, or to what extent it means the public sector is effectively subsidising private contractors.26 One tax advice firm told us that this issue has been raised with HMRC for some time, but HMRC has no current plans to address it.27 17 Qq 44–45 18 Qq 46, 48 19 ICAEW written evidence dated 11 February 2022 20 Q55 21 Q22 22 Qq 62, 64 23 Q56; C&AG’s Report, paras 4.12–4.13 24 Q15 25 C&AG’s report, paras 4.13–4.14 26 Qq 15, 17 27 Contractor Calculator written evidence dated 12 February 2022; C&AG’s report, para 19 Lessons from implementing IR35 reforms 11 2 Understanding the impacts of the IR35 reforms The impact of the reforms on workers and labour markets Show less

For example, in HMRC’s latest research into the impacts of the reforms impacts on public bodies, 19% of ‘sites’ (a single location of an organisation that administers its own payroll) and 34% of ‘central bodies’ (bodies providing payroll services for multiple locations or organisations) reported that they had found it more difficult to fill contractor vacancies since April 2017.34 When reporting its findings, HMRC focuses on the experience of the majority rather than the problems faced by the large minority.35 Understanding which sectors have been particularly affected Show less

HMRC has estimated the cost to hiring organisations, but its modelling is based on a theoretical minimum needed to comply, rather than an estimate of what it actually costs organisations to administer the reforms in practice. While HMRC revisited its cost estimates in light of challenge and recommendations it received from a House of Lords inquiry in 2020, its basic approach has not changed. This means it is still based on a theoretical minimum, and still only covers the private sector.46 HMRC estimated that ongoing costs for the private sector would be £8.4 million a year, and that 36 Q25; 37 Q21; HC Committee of Public Accounts, BBC and personal service companies, Ninetieth Report of Session 2017–19, HC 1522, April 2019 38 C&AG’s Report, para 3.7 39 Qq 25, 75 40 C&AG’s Report, paras 26b, 5.11 41 Q51 42 Qq 36, 37; C&AG’s Report, para 13 43 Q36 44 Q37 45 Q69; C&AGs’ Report, para 3.3 46 Qq 26, 65; C&AG’s Report, para 5.10 Lessons from implementing IR35 reforms 13 240,000 PSCs would need to have their tax status assessed.47 This means an average cost to hiring organisations—to determine the tax status and perform all other administrative activities—of £35 a year per PSC.
