IR35 has profoundly impacted the contracting world since 2000. How do these tax rules affect umbrella company employees?
IR35 and Off Payroll – the basics
The IR35 rules target individuals who provide professional services to clients through an intermediary (usually a limited company).
The legislation – which became law in 2000 – determines whether an individual would be considered an employee if the intermediary (the limited company) did not exist.
If the individual is found to be a disguised employee, they will be subject to standard employment taxes on their contract income.
In 2017, new Off Payroll working rules were implemented for public sector contractors due to apparent non-compliance with the original IR35 rules.
These rules were extended to private sector businesses in April 2021. The new rules require end-clients to determine a worker’s IR35 status.
If you work through your own limited company for a small private sector client, your company remains responsible for determining IR35 status under the original rules.
For medium and large private sector clients, and public sector bodies, the client is responsible for the status determination.
IR35 and Umbrella Companies – do the rules apply?
So, what happens if you are contracting via an umbrella company rather than your own limited company?
In short, IR35 does not apply if you work via a genuine PAYE umbrella company.
As an umbrella company employee, all of your income is already taxed as employment income.
You do not have to carry out an IR35 status assessment for an umbrella engagement. However, IR35 may still be the reason a client or agency has decided to offer the role on an umbrella-only basis.
Some common umbrella company IR35-related questions
Do I have to use an umbrella if I’m caught by IR35?
Not necessarily. Although there is usually little tax advantage to continuing through a limited company for an engagement that falls inside IR35, you may prefer to keep your company running, as future contracts may fall outside the rules.
Some accountants also have umbrella companies within the same organisation, so you can use a flexible contract to switch between trading structures easily, depending on the IR35 status of your current contract.

Can a client force me to use an umbrella company?
Since the April 2021 Off Payroll rollout to the private sector, many risk-averse clients have blanket banned limited company workers.
As a result, many large clients will only hire you if you’re working through an umbrella company.
They can’t force you to do anything. You can either accept the contract (as an umbrella employee) or look for another contract.
This is still a feature of the contracting market, particularly where clients do not want to engage PSCs.
Why do some clients prefer umbrella workers?
For clients and agencies, umbrella working removes the need to engage the contractor through a PSC.
The umbrella employs the worker and pays them through PAYE, so income tax and employee NICs are deducted through payroll.
This can simplify the supply chain from an IR35 perspective, although agencies and clients now face additional PAYE risk when umbrellas are involved.
From 6 April 2026, recruitment agencies can be held jointly and severally liable where an umbrella company fails to account correctly for PAYE. Where there is no agency in the chain, this liability can fall on the end client.

Can a recruiter force me to use a particular umbrella company?
Most large recruitment agencies have preferred supplier lists (PSLs).
A PSL contains a select number of umbrella companies which the agency is prepared to work with.
An umbrella being featured on a PSL should not be taken as a guarantee of quality, so you should still carry out your own checks.
Again, recruitment agents can’t force you to use a particular umbrella. However, in this difficult market, you might find it easier to use an umbrella a recruiter ‘recommends’ than a non-PSL firm of your choice.
What is an ‘IR35 compliant’ umbrella?
We often see umbrellas using this term in their marketing. It is misleading, as all genuine PAYE umbrella companies are outside the scope of IR35 for the umbrella employment because the worker is already taxed as an employee.
There’s nothing extra an umbrella company can do to be ‘IR35 compliant’.
The phrase also tells you nothing about the umbrella’s wider compliance, including whether PAYE, holiday pay and other deductions are being handled correctly.
Are umbrella companies responsible for determining IR35 status?
As discussed above, umbrella companies are not responsible for determining IR35 status for workers they employ through PAYE.
The IR35 rules apply where services are provided through an intermediary such as a personal service company (PSC). As umbrella company workers are already taxed as employees, an IR35 status assessment is not required for that umbrella employment.
How does umbrella pay work?
The rate paid to an umbrella company is not the same as the worker’s gross taxable pay.
The assignment rate normally has to cover employment costs such as employer’s National Insurance, the Apprenticeship Levy where applicable, and the umbrella’s margin before the worker’s gross pay is calculated.
Income tax and employee NICs are then deducted from gross pay.

Make sure you only use a reputable umbrella
Umbrella companies are subject to tax, employment and payroll law, but there has historically been no dedicated licensing regime for the sector.
The government has been introducing further regulation and enforcement measures, including the April 2026 PAYE liability changes, and is also developing wider oversight of umbrella companies.
This means that a few unscrupulous players coexist in the marketplace with established, solid umbrellas.
Only ever use a UK-based PAYE umbrella company. Look for umbrellas audited by the FCSA or Professional Passport.
More umbrella companies also use payroll auditing software (like SafeRec) to provide an additional check that deductions from employees’ pay are made correctly.
Accreditation or payroll auditing can help with due diligence, but neither should be treated as a guarantee on its own.
Be wary of any umbrella promising unusually high take-home pay or offering arrangements involving loans, advances, offshore payments or supposedly non-taxable income. These can be strong indicators of tax avoidance arrangements.
