How do we help industry as a whole?

  • Widespread adoption of our model will substantially elevate the capability of industry to meet the regulatory, compliance and reasonable care bar set by HMRC, without incurring material cost or risk.
  • This in turn will lessen the requirement for HMRC disputes and reduce the probability of high profile HMRC victories destabilising the rest of the private sector’s appetite for outside IR35 engagement.
  • Unless and until the public sector catches up, private sector organisations can continue to retain the edge in terms of talent acquisition and retention.
  • 34square can drive all of this with no disruption of your existing relationships with one another and without demanding a percentage of the commercial arrangements in place.
