The UK’s IR35 tax legislation, introduced by the HM Revenue and Customs (HMRC) in 1999, has long been a source of confusion and debate for taxpayers, tax advisers, and legal professionals. The primary aim of this legislation is to tackle the issue of workers avoiding income tax and National Insurance Contributions (NICs) by providing their services through Personal Service Companies (PSCs) instead of being direct employees.
Despite high expectations for the March 2023 Budget to clarify or amend IR35, the Chancellor still needs to address the issue. This decision was unsurprising, as the current Prime Minister, Rishi Sunak, was responsible for the most recent reforms in this area. Understanding IR35 and its implications is essential for contractors working through PSCs and the businesses that engage them. HMRC’s guidance on IR35 provides a framework for determining whether a contractor falls within the scope of the legislation. The key factors to consider include the following:
- Control: Does the contractor have autonomy over their work and working hours?
- Mutuality of Obligation: Is there an ongoing commitment between the client and the contractor to provide and accept work?
- Substitution: Can the contractor send a replacement to complete the contracted services?
The General Anti-Abuse Rule (GAAR) also plays a role in IR35 enforcement. This rule aims to counter tax avoidance schemes that exploit loopholes in tax law. For example, if a contractor is found to be operating within IR35 but avoiding tax through aggressive arrangements, GAAR could be applied to challenge their position.
HMRC’s Check Employment Status for Tax (CEST) tool offers a starting point for businesses to assess their contractors’ employment status. This online tool asks questions about the key factors outlined above and determines whether the contractor falls within IR35.
Clients are responsible for taking “reasonable care” in assessing their contractors’ tax status. HMRC guidance explains that “reasonable care” will vary depending on the client’s circumstances. If a client fails to exercise reasonable care, they may be treated as the contractor’s deemed employer for tax purposes, potentially incurring additional tax liabilities.
