International Payroll

UK payroll for international businesses — run by a UK-based, CIPP-qualified team that already processes payroll in-house for more than 250 companies.

Employing people in the UK from overseas brings a payroll regime that looks nothing like the one at head office: PAYE registration, Real Time Information filings on or before every payday, workplace pension duties, and statutory payments with their own acronyms and deadlines. Getting it wrong is expensive; explaining it across time zones is exhausting.

We act as the UK payroll arm for international groups: registering the UK employer with HMRC, running compliant gross-to-net payroll for UK-based staff, handling auto enrolment, and reporting back to your head office or global payroll provider in the format they need. One UK contact, business-hours responses, and no local knowledge gaps.

Payroll for Overseas Employers with UK Staff

A company with no UK entity can still have UK payroll obligations the moment it hires someone who works here. We advise on whether a PAYE scheme is required, register it with HMRC, and run the payroll — including the cases where an overseas employer has no UK presence and the compliance burden sits in unfamiliar territory. Where employer National Insurance obligations fall differently because the employer is non-resident, we make sure the scheme is set up on the correct basis from the start.

UK Subsidiaries of International Groups

For international groups with a UK subsidiary, we run the local payroll to UK rules while reporting upwards in the group's format and currency conventions. Head office gets consolidated, predictable reporting; UK employees get accurate payslips, pension contributions and statutory payments; HMRC gets its RTI submissions on time. We work alongside your group finance team or global payroll platform rather than forcing either to learn UK legislation.

Inbound and Expatriate Employees

Employees arriving in the UK mid-year, split-year cases and staff on assignment bring payroll questions that standard software does not answer: which earnings are within PAYE, what tax code applies, and how UK obligations interact with home-country arrangements. Our payroll team works with Acumon's tax specialists — many with prior HMRC experience — so expatriate payroll questions are answered once, correctly, rather than guessed at every pay run.

Everything a UK Payroll Must Do

However international the ownership, a UK payroll has the same statutory workload as any other: RTI submissions on or before each payday, auto enrolment assessment and pension deductions, statutory sick, maternity and paternity pay, P60s and P11Ds at year end. All of it is included, run by the same CIPP-qualified team that handles our domestic payrolls.

Coordination with Global Providers and Advisors

Many international clients run a global payroll platform or use advisors in their home country. We slot into those arrangements as the UK specialist: providing the local calculations and filings, answering the UK-specific questions, and delivering output files in whatever format the global process expects. You keep your existing structure; the UK piece simply becomes reliable.

Common Questions

Frequently Asked Questions

We have no UK company — can we still employ someone in the UK?
Yes. An overseas company can employ UK-based staff without incorporating here, but it will usually still need a UK PAYE scheme, and workplace pension duties apply to UK workers regardless of where the employer is based. The correct setup depends on whether the company has any UK presence, so this is worth getting right before the first payday. We advise on the right structure, register the scheme and run the payroll.
Can you work with our global payroll provider?
Yes — that is how many of our international engagements are structured. Global platforms are good at consolidation but the UK legs still need local expertise: RTI, auto enrolment, statutory payments and HMRC correspondence. We provide the UK processing and filings and deliver output in the format your global provider or head office expects.
How is payroll different for employees seconded to the UK?
Assignees raise questions a domestic payroll never meets: residence status, which earnings fall within PAYE, National Insurance liability, and how UK withholding interacts with home-country obligations. The payroll mechanics are only half the answer — the tax analysis has to come first. Because Acumon has tax specialists in-house, including advisors with prior HMRC experience, we resolve the tax position and then run the payroll to match it.
What do you need from us to get started?
For a new UK employer: company or branch details, employee contracts and start dates, and salary information — we handle PAYE registration and pension scheme setup from there. For an existing payroll transferring to us: year-to-date figures and current scheme references. Most international clients are live within one pay cycle, and we run in parallel with any existing arrangement until the numbers reconcile.
