Satis Tax provides specialist tax and accountancy advice to individuals and businesses in the UK, US and throughout the world.

Founded in 1990 by Ross Badger, who remains with the business to this day, we are based in Pall Mall, London. However, our clients are spread throughout the globe.

Our clients typically have complicated affairs. Our team helps them navigate that world of complexity. Ensuring they remain compliant while helping to reduce tax and increase wealth.

We have also recently been approved for e-filing of US tax returns, which makes the submission process even more efficient for our clients.

Navigating complexity

As our clients’ trusted adviser, it’s our job to make their life easy, while ensuring they comply with all tax jurisdictions that apply to them and their business.

Our clients enjoy a single point of contact, who has unrivalled knowledge of the UK, US and worldwide tax systems. When appropriate, that person also works closely with our sister company, Satis Wealth Management. Having their advisers under one roof ensures that people with assets in the US, the UK and elsewhere in the world benefit from a coherent tax and investment strategy.

Now with over three decades of experience, we’re here for the long-term, acting as a trusted adviser to our clients, no matter where in the world their life takes them.

The story behind the Satis name

‘Satis’ is a stem-word which means ‘plenty’, ‘fulfilled’ and ‘complete’.

The three ‘tears’ which feature in the emblem of the Satis logo come from the tomoe, a weapon wielded by Daikoku, the Chinese God of Prosperity.

What our clients say

As an American residing in London, I have complex tax requirements having to file both in the USA along with the UK.

Satis Tax has not only undertaken this massive assignment with rigour, but more importantly, it has been the very personal engagement and insightful counselling that has shaped the relationship beyond the professional requirement. Their work undertaken has been flawless in its execution. Without hesitation I would recommend their services to all those that require a level of professionalism that goes beyond a remit.


Ross Badger, and now his team at Satis Tax, has been handling my US and UK tax affairs for almost 25 years. Aside from the high quality of the firm’s work and its tireless effort to ensure that tax planning in both jurisdictions is as efficient as permissible, what I have particularly liked is the unstinting personal service that Ross and his colleagues provide. But, perhaps, the best indication of my satisfaction with Satis’ work is the numerous clients I have referred to the firm all of whom have been equally happy with their experience.


Although tax time is no fun for most people Satis Tax makes it easy and painless. Their knowledge of both US and UK tax requirements along with their quick response to queries has enabled me to spend more time on other pressing issues.

Phoenix, AZ

One or more of the Satis Tax principals has been handling my personal taxes, both US and UK, for over 35 years. That fact speaks for itself. Several aspects of Satis' work impress me: 1) Thorough understanding of both the UK and USA tax systems; 2) Attention to detail; 3) A conservative approach combined with an appreciation that for the client "every dollar/pound matters" when it comes to limiting one's tax liabilities.


Having decided to emigrate to the U.S., I was completely unprepared for how complex the interaction between the UK and US tax systems would be. From initial tax planning advice prior to emigrating, several subsequent complex business transactions, to filing both our UK and US annual returns, I’ve always felt assured that Satis have a complete understanding of the complexities of the tax regulations. This has freed us from the worry of tax compliance in both countries. Over and above keeping us complaint, they have been an invaluable sounding board when we have found ourselves facing personal decisions that have had tax consequences through the years we have been living in the US.
