About Sirius Global Solutions Limited — a UK-incorporated professional consultancy headquartered at Devonshire House, Stanmore, Greater London. We combine tax, VAT, HMRC compliance, payroll, IT, and cross-border incorporation expertise under one roof — serving UK resident businesses and international entrepreneurs across Hong Kong, India, UAE, and Australia since 2018.
Built by professionals who understand that your business does not stop at borders — Sirius Global Solutions brings together tax specialists, HMRC compliance experts, IT developers, and international incorporation advisers under one London roof, serving clients from Stanmore to Sydney.
From a small Stanmore office to a five-jurisdiction consultancy serving hundreds of businesses worldwide — this is the Sirius story.
Sirius Global Solutions Limited was founded in 2018 in Stanmore, Greater London, by a team of professionals who had spent years working within major accountancy firms, corporate legal departments, and technology companies — and noticed the same gap every time: small and medium-sized businesses, as well as ambitious international entrepreneurs, were either underserved by large firms that found them too small, or over-charged by specialists who lacked breadth.
We set out to change that. The name Sirius — the brightest star in the night sky — reflects our founding philosophy: to be the clearest and most dependable light for businesses navigating complex compliance landscapes, whether they are registering for VAT for the first time or incorporating their tenth overseas subsidiary.
From the beginning, we structured ourselves differently. Rather than treating tax, compliance, IT, and international incorporation as separate silos, we built an integrated team where every discipline informs the others. A client incorporating a Hong Kong company receives not just the formation service but automatically benefits from our UK tax team's analysis of the CFC position, our IT team's readiness to build the digital infrastructure, and our payroll team's advice on PAYE for any eventual UK employees.
Today, from our Stanmore base, we serve over 500 businesses and individual clients across the United Kingdom, Hong Kong, India, the UAE, and Australia — in English, Hindi, and Gujarati — and we remain committed to the same core principle: genuinely expert, genuinely accessible, genuinely joined-up advice for every client, regardless of size.
We built Sirius because we believed UK businesses — and the international founders who trust this country as their gateway to the world — deserved advisers who understood both the detail and the bigger picture. Six years on, that belief is the foundation everything else is built on.
Our values are not wall art — they are the practical framework for every piece of advice we give and every deadline we meet.
We check twice, submit once. Whether it is a VAT return, a company incorporation document, or a tax relief claim, we treat accuracy as a non-negotiable minimum — not a differentiator. Errors cost our clients money and reputation; we protect both with rigorous internal review processes on every piece of work we produce.
We do not treat clients as file numbers. We invest in understanding the commercial context of every instruction — your ambitions, your risk appetite, your growth timeline. That context shapes advice that is genuinely useful rather than merely technically correct. Our longest-standing clients have worked with us for over six years because they experience that difference every day.
We never advise in isolation. A UK VAT registration decision may have implications for your Hong Kong subsidiary's supply chain. An India incorporation may change your UK holding company's CFC position. We think across jurisdictions as a matter of course — because your business does not stop at the UK border, and neither should your advisers.
Regulation is complex. Our job is to make it clear. We translate HMRC guidance, Companies House requirements, and cross-border tax rules into plain commercial terms that decision-makers can act on. We never use technical jargon as a barrier to understanding — a client who understands our advice is a client who can make better decisions.
We alert clients to threshold breaches, regulatory changes, and new opportunities before they become problems or missed windows. Our VAT team monitors client turnover for threshold risks. Our incorporation team watches for policy changes in each jurisdiction we operate in. Being proactive is how we justify a long-term advisory relationship — not just a transactional compliance service.
Our clients share their most sensitive financial and commercial information with us. We take that trust seriously. All data is handled under GDPR-compliant protocols, encrypted in transit and at rest, and never shared beyond the professional team working on the engagement. Our confidentiality obligations extend beyond the engagement — permanently.

In this short video, our founding team introduces Sirius Global Solutions — our story, the services we deliver, the jurisdictions we cover, and the values that have guided us since 2018. The best way to understand who we are before we speak.
The most honest way to understand who we are — the words of businesses who have worked with us.
Sirius have been our accountants and company formation agents for three years. What stands out is how they understand both the UK and Indian sides of our business — no other firm we spoke to could do that. Completely reliable, always proactive, genuinely invested in our success. The definition of a trusted adviser.
As a German national setting up a UK company to access the British market, I needed guidance from people who truly understood the regulatory landscape. Sirius delivered from day one — company formation, VAT, PAYE, and even our website. One team, everything sorted within two weeks. Outstanding.
We used Sirius to incorporate in Hong Kong as part of our Asia expansion. What impressed me most was how they coordinated the UK tax implications simultaneously — most firms would have missed that. Six months later they are still managing our HK compliance. Exactly the joined-up service we needed.
