Chartered Accountants
International Tax

Many accountants claim to be “expert” in your business or tax affairs but PetersonSims are a company that truly offers you something different

PetersonSims started as a small accountancy practice serving niche private businesses in the UK.  It has grown into an international company offering business and personal tax advice and support for individuals and large corporations across the globe.  As well as their own team of in-house professionals they work with international experts across the world to ensure they offer their clients a truly global service.

Gerry is a Chartered Accountant with years in practice and in industry; at the sharp end during a recession when many businesses were taking a hit.  He went on to launch and run a £1m+ business in a non-finance sector. This is an accountant you can talk to.  Businesses large and small can benefit from his real-life experience as he has been there and done it, through good times and bad.

Two Tax Directors, Paulette and Oliver, both come from a Big 4 background and both have trained and worked for two of the largest global accountancy firms. They now offer our clients their combined experience of over forty years specialising in international personal tax. PetersonSims offers clients a level of expertise in expatriate taxation normally only found in the Big 4 accountancy firms, but at realistic fee levels. Coupled with this in-house expertise, we have a network of trusted associate firms in key overseas locations who provide expert local advice.

We know all businesses and individuals need to control their costs so we always offer our clients a fixed quote when we are engaged to work; there are no nasty surprises.
