What is an IR35 Status Determination Statement (SDS)?

The Off-payroll legislation sets out the provisions for clients to provide a IR35 ‘status determination statement’ when assessing the IR35 status of contractors. A ‘Status Determination Statement’ (SDS) is a comprehensive statement from the client which:

  • Declares a contractor’s deemed employment status following an IR35 assessment
  • Provides reasons for reaching this conclusion.

The SDS is intended to help combat misclassification of status due to non-compliant blanket or role-based assessments and ensure that any recruitment agency in the supply chain pays the correct tax if the engagement is "Inside IR35". Crucially, the requirement for an SDS is not met if the client fails to take ‘reasonable care’ in arriving at its decision. Should this be the case, the client assumes liability for the tax, and not the recruitment agency.

Consequently, for hiring organisations, providing a valid and accurate status determination statement is essential to meet their statutory obligations and mitigate any financial risk.

What does reasonable care mean?

Though the legislation fails to explain what ‘reasonable care’ means, an examination of HMRC’s own practices and the case law offers some clarity.

Every year, HMRC enquires into thousands of tax returns completed by UK taxpayers. If there is an error leading to a loss of tax, HMRC will often apply a tax-geared penalty for failure to take reasonable care.

A penalty will apply in one of three circumstances where the outcome is a loss of tax:

  1. Where the taxpayer makes a careless error (in providing information to HMRC)
  2. When a third-party supplies information that is false or deliberately withholds information
  3. When a taxpayer fails to notify HMRC that an assessment is too low.

There is some official guidance from HMRC on how reasonable care applies to clients with regards to IR35 status determinations, but readers should be warned that guidance cannot be relied upon in court instead of the case law.

HMRC’s Compliance Handbook also offers some clues as to its approach to reasonable care by providing numerous examples of what is considered ‘careless’ - which is the consequence of not taking reasonable care.

What constitutes reasonable care?

Being a necessary component of an SDS, it’s important to be able to determine what does, and does not, constitute reasonable care when conducting status assessments.

Due to the subjectivity over the reasonable care requirement in the legislation governing Off-Payroll in the public sector (Chapter 10 ITEPA), blanket assessments had become commonplace amongst public sector hirers, typically falling into one of two categories:

  1. Where a client makes an IR35 status decision without conducting an assessment
  2. Where a client assesses a role and applies the status determination to a number of contractors.

However, employment status lawyers have noted that, in the context of a contractor facing an inquiry, reasonable care would constitute:

  1. Acquiring expert advice; and
  2. Making a full assessment on an individual basis.

Though applied to a different context, this would mean that clients conducting blanket status assessments would have failed to have taken reasonable care, on the basis that they failed to assess contractors individually.

This is required in order to consider important factors unique to the contractor which can’t be deciphered from the contract, such as whether they are in business on their own account (IBOOA). As a result, failure to assess contractors on an individual basis could render any subsequent SDS invalid.

What are the consequences of failing to take reasonable care?

Failure to take reasonable care has significant consequences for clients. Under the Off-Payroll legislation, failing to take reasonable care renders the hiring organisation:

  • Responsible for deducting tax from the contractor’s income if deemed ‘inside IR35’;
  • Liable for employer’s National Insurance (NI) and the Apprenticeship Levy; and
  • Liable for any outstanding tax if HMRC successfully challenges a status decision.

There are further potential repercussions. The same logic from HMRC’s Compliance Handbook could easily be applied to any client responsible for conducting a status assessment and providing an SDS:

If HMRC investigates because it suspects that reasonable care has not been taken, it may argue that the client has been ‘careless’ in making its assessment. HMRC then has the right to extend its enquiry window from four to a full six years, increasing the tax risk even further.

The tax liability, coupled with the possibility that HMRC enquiries could stretch as far as six years, imposes a huge financial risk on clients – reinforcing the importance of due diligence.

Successfully defending a blanket or role-based assessment in court would prove a tall order, as HMRC could quite easily demonstrate that not enough detail was looked at. Ultimately, the only way to guarantee meeting the reasonable care requirement is to assess each individual on a case-by-case basis.

A comprehensive status determination is also necessary to mitigate the threat of the potential breakdown of an engagement. If it is clear to the contractor than an assessment has only considered the contract or role in question, they will likely be encouraged to challenge the assessment and potentially litigate. It’s essential that all parties agree the status determination up-front before the work starts.

Clients are advised not to base a status determination on HMRC’s Check Employment Status for Tax (CEST) tool as it omits key areas of law and is unable to provide reasons for having reached a status decision.

How clients can use IR35 Shield to create Status Determination Statements

The main deterrent from complying for clients is the perceived workload involved with taking reasonable care in conducting a status assessment. However, there is a solution through which clients can fulfil their compliance requirements, without incurring significant administrative costs or time.

IR35 Shield is an outsourced SaaS solution available to hiring organisations. Companies can use IR35 Shield’s Collaborative Assessments capabilities to pre-answer some questions on the assessment, ensuring accuracy, before inviting contractors to answer the remainder of the questionnaire.

Between them, contractor and client complete a comprehensive assessment of over 100 questions, spanning the full factual matrix of employment status factors required to demonstrate reasonable care has been taken. This is roughly the same amount of questions that HMRC inspectors will ask when conducting an IR35 investigation, and significantly more than the limited questions currently posed by CEST.

After the final question has been answered, an immediate status determination is made, and a 25-page Status Determination Statement (SDS) is generated, comprehensively detailing the reasons for the final determination while demonstrating reasonable care in the process.
