Off-payroll working (IR35) for overseas engagers

If your company is based overseas and you engage a UK contractor who works through their own limited company, you've probably been told to worry about "IR35". The good news for many overseas businesses is that the off-payroll rules often don't land on you in the way they would on a large UK client. But "often" is not "always" — and getting it wrong is expensive. This guide explains, carefully, when the rules bite and what to do about it.

What "off-payroll" (IR35) actually means

IR35 is shorthand for the rules that test whether someone working through an intermediary — usually their own personal service company (PSC) — is, in reality, working like an employee of the end client. If they are, the engagement is "inside IR35" and broadly the same Income Tax and National Insurance that would apply to an employee has to be accounted for.

Since April 2021, for medium and large clients in the private sector, the responsibility for deciding status and for operating PAYE shifted from the contractor's company to the client (or to the agency that pays the PSC). These are the "off-payroll working" rules. The question for an overseas business is simple to state and harder to answer: do these client-side rules apply to me?

The small-company exemption

The client-side off-payroll rules only apply where the end client is a medium or large organisation. If the client is a small company, the responsibility stays with the contractor's own PSC — the contractor decides their own status and accounts for any tax due. Small is defined using the Companies Act test (broadly, meeting two of three thresholds: turnover, balance-sheet total and number of employees).

Many overseas engagers — and certainly smaller ones — will fall within this "small" exemption, which means the off-payroll obligation does not transfer to them. There is also a long-standing position that the rules are aimed at clients with a UK connection; a wholly overseas client with no UK presence may be outside the client-side regime, leaving the responsibility with the contractor's PSC. This is exactly the kind of point that turns on the detail of your structure, so it must be checked, not assumed.

Who carries the SDS and the PAYE?

Where the client-side rules do apply, the end client must produce a Status Determination Statement (SDS) — a written conclusion on whether the engagement is inside or outside IR35, with reasons — and pass it to the worker and to any agency in the chain. The party that pays the PSC (the "fee-payer") then operates PAYE and accounts for Income Tax and National Insurance on the fees if the engagement is inside IR35.

Where the rules do not apply — for example because the client is small, or genuinely outside the client-side regime — there is no SDS obligation on the client, and the contractor's own company is responsible for assessing IR35 and accounting for any tax under the original (pre-2021) rules.

How this differs from employing via a DPNI scheme

It's easy to confuse two very different situations, so it's worth being clear:

• IR35 / off-payroll is about a contractor who invoices you through their own company. The question is whether that relationship is really employment in disguise.
• A DPNI scheme is about a genuine employee you want to employ directly in the UK with no UK entity. There's no PSC and no "status" debate — you've decided to employ them.

If you actually want an employee, employing them properly via a DPNI scheme avoids the IR35 question altogether — because there is no intermediary. If you genuinely want a contractor, IR35 is the framework that decides how that engagement is taxed. Choosing the right relationship up front saves a great deal of trouble later. Our route finder can help you think this through.

What should an overseas engager do?

A sensible, low-drama approach:

• Be honest about the relationship. Decide whether you want an employee or a genuine contractor — and document the working practices to match.
• Check your own size and UK footprint. The small-company exemption and the overseas-client position both turn on facts about you, not the contractor.
• If in doubt, get a status review. A proper assessment of the engagement is far cheaper than a PAYE settlement with interest and penalties.
• Keep records. Whatever position you take, write down why — that evidence matters if HMRC ever asks.

The bottom line

For many overseas businesses engaging a UK contractor through a limited company, the client-side off-payroll obligation does not transfer — particularly where you're a small company or have no UK presence — leaving the contractor's own company responsible. But the exemptions hinge on facts that are easy to get wrong, and the cost of misjudging it is real. If you actually want an employee, employing directly via a DPNI scheme sidesteps IR35 entirely. Either way, a short conversation up front is the cheapest insurance you'll buy.

Quick FAQ

Does IR35 apply if my company is entirely overseas?
The client-side off-payroll rules are aimed at clients with a UK connection, and a small client is exempt regardless. A wholly overseas client may be outside the client-side regime — but this is fact-specific and has changed over time, so check it for your situation.

What is an SDS?
A Status Determination Statement: the client's written decision on whether an engagement is inside or outside IR35, with reasons, passed to the worker and any agency. It's only required where the client-side rules apply.

Is it simpler to just employ the person?
Often, yes — if you genuinely want an employee. Employing directly via a DPNI scheme removes the intermediary and the IR35 question with it.
