An inside IR35 contract is one where, for tax purposes, the engagement looks like employment. Income tax and National Insurance are deducted before you are paid — usually through an umbrella company that employs you for the assignment, or through the agency's own PAYE — and you cannot be paid gross through your own limited company in the way an outside role allows.
Status is decided role by role, never by job title. Where the end client is a medium or large organisation, the client must assess each engagement and issue a Status Determination Statement; the same skills can be inside at one client and outside at the next. The status shown on our board is stated by the recruiter or employer advertising the role — read the determination and the contract, and take professional advice if anything is unclear. Nothing on this page is tax advice.
New to the rules? Start with what IR35 is and how it works, or compare the live outside IR35 contracts.
The rate on an inside IR35 advert is often an umbrella rate — the figure before the umbrella deducts employment costs and runs payroll — so the money that reaches you is lower than the number suggests. That does not make it a bad contract: inside roles usually carry holiday pay, pension auto-enrolment and employee protections that an outside engagement does not, and for many contractors the certainty is worth it.
The only honest comparison is take-home on the actual rate: our umbrella company take-home calculator shows the inside picture, and the IR35 tax calculator shows what the same rate would leave you working outside through your own company. Every listing on this board with a usable rate also shows a quick take-home estimate on the card.
An inside IR35 contract is one where, for tax purposes, the engagement looks like employment: income tax and National Insurance are deducted before you are paid, usually through an umbrella company or the agency's PAYE. Status is decided role by role on the working practices, and the status on our listings is stated by the recruiter or employer advertising the role.
Most inside IR35 roles are paid through an umbrella company or agency PAYE. The umbrella employs you, invoices the agency, deducts employment costs, tax and NI, and pays you a net salary with holiday pay accrued. Some clients allow payment to your own limited company with tax deducted at source (a deemed payment), but many agencies insist on umbrella or PAYE.
The headline rate on an inside role is often an umbrella rate — the figure before employment costs and payroll deductions — so the take-home is lower than the number suggests. Compare like-for-like rates with our umbrella take-home calculator, and remember an inside role usually brings holiday pay and employee protections that an outside role does not.
Yes. Status follows the specific engagement — the contract terms and how the work is actually done — not the job title. The same role can be inside at one client and outside at another, and a determination can change at renewal if the working practices change.
Use the search on this page, or filter any search on our jobs board by IR35 status — the card shows the status wherever the advert states it. New contracts are added daily, and you can set up a free email alert for inside IR35 roles matching your skills.
