This article is for Irish business owners and finance directors who engage contractors and want to avoid a costly Revenue reclassification.
If you're worried about whether your contractors might be deemed employees during an audit—or you've already received a determination letter from Revenue—this guide covers how Revenue decides employment status, your options for challenging a reclassification, and how to structure contractor relationships properly from the start.
Key Takeaways
• Revenue determines employment status based on working reality, not contract labels, examining control, exclusivity, and financial risk factors.
• You have 30 days to challenge a Revenue determination through internal review or appeal to the Tax Appeals Commission.
• Companies face backdated PAYE, PRSI, and USC liabilities for up to four years, plus interest and penalties on reclassified contractors.
• Build genuine self-employment indicators: ensure contractors work for multiple clients, contract for deliverables not time, and allow substitution.
• Gather evidence immediately when audited: contracts, multi-client proof, contractor invoices, equipment ownership records, and substitution arrangements.

What to Do If Revenue Classifies Your Contractors as Employees
Few things land harder on a growing company than a Revenue audit that ends with a reclassification decision.
One letter, and suddenly every contractor you have paid over the past four years may be treated as an employee. The PAYE, PRSI, and USC that should have been deducted and remitted falls on the company. The interest and penalties start accumulating from the date each payment was made.
It is one of the most expensive compliance failures an Irish company can face, and it happens far more often than founders expect.
This guide explains how Revenue approaches this issue, what your options are when a determination goes against you, and how to prevent it from happening again.
Why This Keeps Catching Companies Out
The instinct to engage people on a self-employed basis is understandable.
It avoids employer PRSI. It reduces administrative complexity. And in many industries, particularly tech, creative, and professional services, working with contractors is simply how the market operates.
The problem is that Irish tax law does not care what the contract says. What matters is the reality of the working relationship.
Revenue has been increasing audit activity in this area, and the stakes are significant enough that every company engaging contractors should understand where the line is.
What Is the Revenue Code of Practice on Employment Status?
Revenue and the Department of Social Protection jointly publish a Code of Practice for Determining Employment or Self-Employment Status of Individuals.
The Code sets out the factors Revenue considers when deciding whether a working relationship is one of employment or genuine self-employment.
No single factor is decisive. Revenue looks at the overall picture.
Indicators that point toward employment include:
- The individual works set hours or is told when to work
- The company controls how the work is done, not just the outcome
- The individual cannot subcontract the work or send a substitute
- The individual is integrated into the company's operations, uses company equipment, and follows internal procedures
- The individual works exclusively or predominantly for one company
- The individual has no financial risk, does not invoice for expenses separately, and does not provide their own materials or tools
Indicators that point toward genuine self-employment include:
- The individual controls how and when the work is done
- The individual bears financial risk, for example by fixing their price and absorbing cost overruns
- The individual works for multiple clients simultaneously
- The individual can subcontract or send a substitute to complete the work
- The individual provides their own equipment and materials
- The relationship is project-based with a clear start and end point
A written contract describing someone as a self-employed contractor while the day-to-day reality looks like employment will not protect the company. Revenue will look past the label.
How Does Revenue Raise a Reclassification Issue?
Most reclassification issues surface during a PAYE compliance audit.
Revenue may select your company for audit based on sector risk, a tip-off, or random selection. During the audit, they will typically request contracts, invoices, payment records, and sometimes interview the contractors themselves.
In some cases Revenue raises the issue following a complaint from a contractor who applies for a social welfare benefit, such as jobseeker's allowance, and is found to have no PRSI record because they were always paid gross.
Once Revenue forms a view that a contractor should have been treated as an employee, they will issue a determination setting out the amount of PAYE, PRSI, and USC they consider should have been deducted, plus interest and potentially penalties.
What Happens When You Receive a Revenue Determination?
Do not ignore it and do not accept it without review.
A Revenue determination is not automatically final. You have the right to challenge it, and the strength of your challenge depends heavily on the documentation you have and how the working relationship was actually structured.
The first step is to analyse each contractor relationship individually against the Code of Practice factors. A determination that treats all contractors as employees in a blanket way may be wrong in some cases even if it is right in others.
Gather the evidence that supports your position. This includes:
- Signed contracts clearly establishing the self-employed basis
- Evidence that the contractor worked for multiple clients during the same period
- Invoices raised by the contractor on their own company letterhead
- Records showing the contractor used their own equipment
- Evidence of substitution arrangements or subcontracting
- Correspondence showing the contractor had genuine control over how the work was delivered
How Do You Dispute a Revenue Determination?
Revenue offers an internal review process. Alternatively, or if a formal assessment has issued, you may appeal directly to the Tax Appeals Commission within the statutory timeframe (generally 30 days).
If you disagree with a determination, you can request a formal review by a Revenue officer not involved in the original decision.
The review must be requested within the timeframe specified in the determination letter, typically 30 days.
Submit a detailed written response setting out, contractor by contractor where relevant, why you believe the Code of Practice factors support self-employment status. Include all supporting documentation.
If the internal review does not resolve the dispute in your favour, you can appeal to the Tax Appeals Commission, which is an independent statutory body.
The Tax Appeals Commission process involves a formal hearing where both Revenue and the company can present evidence and argument. Decisions of the Commission can be further appealed to the High Court on a point of law.
How Do You Prevent This from Happening Again?
The most effective protection is building the genuine indicators of self-employment into how you structure contractor relationships from the outset, not just into what the contract says.
In practice, this means:
- Ensuring contractors work for multiple clients and actively encouraging that
- Contracting for outcomes and deliverables rather than time and attendance
- Avoiding giving contractors a company email address, business cards, or access to internal systems beyond what the project requires
- Paying on invoice rather than salary, with no fixed monthly amount
- Allowing contractors to subcontract or substitute where genuinely appropriate
- Reviewing each contractor relationship periodically against the Code of Practice factors
If a contractor relationship begins to look more like employment over time, as projects extend and the working relationship deepens, address it proactively rather than waiting for Revenue to raise it.
Some companies choose to engage contractors through their own personal service companies rather than as individuals. This adds a corporate layer between the company and the individual and can, in the right circumstances, support self-employment status. However, it is not a guaranteed fix if the underlying working relationship still looks like employment.
