IR35 For Clients

Reforms to IR35 legislation, came into force in April 2017 for the public sector and were extended to the private sector in April 2021. This means that the responsibility for determining the tax status of all personal service company (PSC) interim workers has been passed to the hiring organisation, including potential liability for tax and national insurance contributions.

IR35 exists to address the relationship between the end hirer and the contractor to understand if it is an employment relationship or not, therefore all assignments now need to be assessed to understand if they fall in or outside IR35.

If a contract is found to fall inside IR35 then the contractor is expected to pay the same amount of tax and NI that a permanent employee would pay.

Similarly, the end hirer is expected to pay the matching NI and both parties are held accountable if the funds aren’t paid correctly.

When a contract assignment is assessed as inside IR35 there are 3 different ways a candidate can now engage:

PAYE – all statutory deductions for PAYE tax, NI and pensions are deducted at source. Holiday pay is accrued and paid when you are on holiday. Auto enrolment onto a pension scheme (can opt out).

Umbrella Company – there is a contract with an Umbrella company that manage all statutory deductions. Vantage pay the Umbrella company and they are responsible for paying the contractor. The decision on holiday pay accruals is down to the contractor. There will be a small weekly fee charged by the Umbrella company. Contractors chose Umbrella companies to simplify continuity of earnings for their own financial planning ie mortgages / pension provision.

Deemed Ltd - the contractor operates through their Ltd company but the liability shifts to Vantage as the deemed employer and therefore the gross rate is reduced to account for Employers NI. Holiday pay is included into the gross rate and not accrued. Contractors are not auto enrolled onto a pension. Vantage deduct PAYE tax and Employee NI. Corporation Tax and tax on dividends may still apply.

If a contract assignment is deemed to be outside IR35 then the contractor is considered to be a genuine contractor and not a disguised employee. This means the hiring organisation and HMRC consider the contractor to be self-employed and the contractor must pay the right amount of tax and NI for the money they receive for their work.
