IR35 for Employers Hiring IT Contractors in 2026
IR35 can affect how you engage IT contractors, how attractive a role looks to the market, and what responsibilities sit with your organisation during the hiring process.
Talent Today helps UK businesses understand the practical side of IR35 when hiring IT contractors. This guide gives a straightforward overview of what employers need to consider, what “inside” and “outside” IR35 usually mean in practice, and where mistakes can create problems during hiring.
What IR35 means in practice
IR35 refers to the off-payroll working rules. In simple terms, the rules are designed to assess whether a contractor is genuinely operating as an independent business or would be treated like an employee if engaged directly.
For employers, the issue is not just tax terminology. IR35 affects how a contract role is positioned, how contractors respond to it, and what steps need to be taken before the engagement goes live.
That is why it is important to think about IR35 early, rather than treating it as an admin task after the hiring decision has already been made.
Who the rules apply to
The off-payroll working rules can apply where a worker provides services through an intermediary, such as a personal service company, and the engagement needs to be assessed for tax purposes. HMRC’s guidance sets out responsibilities for clients, agencies and fee-payers depending on the structure of the labour supply chain.
From an employer perspective, the key point is simple: if you are hiring IT contractors through this kind of arrangement, IR35 may be relevant and should be considered properly before the role goes to market.
What employers need to do
Where the rules apply, employers may need to make a status determination, take reasonable care when reaching that decision, provide a Status Determination Statement, and have a process for handling disagreements. HMRC’s guidance for clients is explicit on these responsibilities.
In practical terms, that means thinking clearly about:
How the role will operate in reality
How much control the business will have
Whether the engagement looks like an independent contract assignment or something closer to employment
How the decision will be documented and communicated
Inside vs Outside IR35
When employers talk about a role being “inside” or “outside” IR35, they are usually talking about how the engagement is expected to be treated under the off-payroll rules. In practical hiring terms:
Inside IR35
The role is being treated in a way that is closer to employment for tax purposes. This can affect contractor take-home pay and often influences how attractive the opportunity feels in the market.
Outside IR35
The role is being positioned more like a genuine independent contract engagement. Contractors often look closely at whether that position is realistic and properly supported by the working arrangement.
The important point is not the label on its own. It is whether the actual engagement supports that position.
IR35 affects more than compliance
It can directly influence:
contractor attraction
day-rate expectations
speed to hire
shortlist quality
the type of contractors who will engage with the role
If the IR35 position is unclear, unrealistic or badly communicated, good contractors may step away early or ask tougher questions before progressing. IR35 should be part of the hiring conversation from the start, especially for contract roles in software, cloud, cyber security, data, architecture and project delivery.
Common employer mistakes
Employers often run into problems with IR35 not because the rules are impossible to understand, but because the role has not been thought through properly before hiring begins.
Common mistakes include:
being unclear on the likely IR35 position before going to market
treating every contractor role the same regardless of context
using vague or contradictory briefs
making rushed determinations without enough care
failing to explain the engagement clearly to agencies or contractors
assuming the label matters more than the actual working arrangement
A clearer brief and a better-defined engagement usually improve both compliance and hiring outcomes.
Some contract roles are straightforward. Others are not. If you are hiring for specialist architecture, niche cyber security, transformation leadership, AI, or high-impact programme work, broad IR35 guidance may not be enough on its own. The more specialist, sensitive or commercially important the role is, the more useful it becomes to sense-check the engagement properly before hiring starts.
HMRC also provides its Check Employment Status for Tax tool, but the quality of the outcome depends on understanding the engagement accurately in the first place.
