UK subsidiary accountants for US and European companies
Why overseas-owned companies need a UK specialist
A UK subsidiary has to follow UK rules whatever its parent does. Year-end accounts, corporation tax, VAT, PAYE and Companies House filings all run to UK deadlines, and the directors carry personal responsibility for getting them right.
Your parent company is usually in another time zone, reporting under another framework and expecting numbers on its own timetable. A generalist can struggle to bridge the two. We act for the UK subsidiaries of US and European parent companies, and have done since we were founded. We provide UK accounting services only, and work alongside your parent’s finance team.
You get a named accountant, monthly management accounts and a cash-flow forecast, all delivered online. If you would like to meet when you are in the UK, we have offices in Manchester and High Wycombe, and we also act as online accountants for UK businesses.
Acting for the UK arm of US and European groups
We currently act for UK subsidiaries owned by US and European parent companies, from newly formed entities to established trading businesses. We take on the UK side of the accounting, so your own team can concentrate on the group.
Fees depend on the size and complexity of the subsidiary. We have a transparent pricing matrix that we will share with you during an enquiry call

UK accounts and corporation tax
Statutory year-end accounts and the corporation tax return, prepared to UK rules and filed on time. We explain the UK treatment of anything that differs from how your parent reports.

VAT, payroll and pensions
VAT returns, payroll, PAYE and auto-enrolment pensions run online to HMRC deadlines, with your UK staff paid correctly and on time.

Companies House and compliance
Confirmation statements, director appointments and changes, HMRC registrations and the other UK filings that sit with a company and its directors, handled so nothing lapses.

Monthly reporting for your parent
Monthly management accounts and a rolling cash-flow forecast, sent in the format and to the timetable your parent company needs.
Taking on a UK subsidiary is a structured process, led by a named accountant. Most of the work happens before you notice it, and the handover usually takes 1 week.

Intro call
Tell us about the UK company, its parent and what the group needs from the UK accounts. We come back with a clear proposal and a price.

Handover and set-up
We take over from any previous accountant, register for what is needed with HMRC and Companies House, and connect your cloud accounting.

A steady monthly rhythm
Your books stay current, your parent receives numbers on schedule, and we plan UK tax and deadlines ahead so there are no surprises.

I’d like to give a special thank you to Molly Witty at StriveX, who supported me throughout my year-end accounting process. She has been incredibly helpful, patient and professional, always taking the time to explain everything clearly and answer my questions, no matter how small. She made the whole process feel much easier. I really appreciate her support and the personal approach she brings to her work. Thank you, Molly! I would highly recommend working with her.

I’ve recently onboarded my business with striveX and the whole experience has been excellent from start to finish. From my initial enquiry, everything has been handled promptly, professionally and, most importantly, in a really straightforward way. Jaya, Elysha and Tyarnna have all been first class throughout. They’ve been responsive, helpful and have made the whole onboarding process feel incredibly easy. One of the things I’ve particularly appreciated is how upfront and transparent everything is, especially when it comes to costs. There are no grey areas or surprises, and you know exactly where you stand from the outset. That was a big factor for me when choosing an accountant. It’s also refreshing to deal with a firm that feels modern and genuinely proactive, rather than simply being there to deal with the numbers at the end of the year. You get the impression they actually want to understand your business and help you move it forward. If you’re looking for a forward-thinking, proactive accountant who is easy to deal with and transparent about what they charge, I’d definitely recommend striveX. So far I couldn’t be happier with the decision to move across.

After a bad experience with my previous accountant I am so pleased I found Strive X! I used to dread anything to do with taxes and spreadsheets, but they have completely turned this around and I am now studying for my AAT Level 2 qualification. Not only are the team brilliant at what they do, they are also the most friendly, approachable and down to earth people who really care. A special shout out to Natasha the CIS queen for working so hard to sort out our CIS reclaims and to Amy for all her help with understanding tax planning. You are both amazing!

I’ve been incredibly impressed with StriveX - the attention to detail, proactive communication and ensuring I have all the information available to me to inform my decisions. The service experience is second to none. Thank you - particularly to Elysha, Amy-Leigh, Tyranna and Jack!

Truly informative and have helped me understand my own business much more. Molly and Elysha have been superb in their guidance, helping me navigate the business and increasing my level of understanding around tax and accounts. Wish I'd known about StriveX when I first started my company. I'm quite certain I'd be in an even better position now.

We've been really impressed with the service from Strive X. What stands out most is how organised they are and how clearly they communicate throughout the process. Everything is well planned, deadlines are clearly explained and we're always kept up to date, which makes dealing with our accounts with much less stress. The team is friendly, approachable and always happy to answer questions, no matter how big or small. A special mention to Amy, who led our recent tax planning meeting. She was incredibly helpful, explained everything in a way that was easy to understand and made sure we felt confident about the decisions we were making. Elysha is also really helpful and makes sure we are working together efficiently to suit the business and is very adaptive and supportive with that. It's reassuring to work with a team that is so professional, organised and easy to deal with. We'd happily recommend them to anyone looking for an accountant.

We've had such a positive experience since joining Strive. The whole team consistently goes above and beyond, but I wanted to give a special mention to Amy and Elysha. Amy recently led our tax planning meeting, and somehow managed to make a topic that can often feel overwhelming and serious both engaging and enjoyable. She put so much time, effort, and thought into the session, making it interactive, easy to understand, and dare I say, fun! I came away feeling confident in the decisions we were making, reassured that our accountants truly understand both us and our business, and grateful to have experts who genuinely care about our success. Elysha has also been fantastic throughout our time with Strive, always approachable, supportive, and happy to help whenever we've needed guidance. It's rare to find an accountancy team that combines expertise with such a personal, supportive approach. We genuinely appreciate everything Amy, Elysha, and the wider Strive team do for us, and feel incredibly lucky to have them supporting our business.
