Our Services

US & UK International Tax

For Americans living in the UK, managing tax is always a delicate balancing act between your US and UK tax obligations.

Contact Us

We provides specialist advice for individuals and families in this situation to ensure that their positions are aligned in both jurisdictions and that they are not suffering double tax.

We can also provide advice should a US person decide that they wish to expatriate and working with their immigration attorney, can help to assess the tax consequences for doing so and file the relevant forms with the IRS.

For other, non-US foreign nationals living in the UK, your residence and domicile position can heavily affect your UK tax liability and we provide bespoke advice in this area to ensure that your position is optimised.

US Gift and Estate & UK Inheritance Tax

For Americans living in the UK, balancing their US Gift and Estate Tax position with any potential UK Inheritance Tax exposure can be incredibly tricky.

Contact Us

The UK is one of the few jurisdictions that has an Estate Tax Treaty with the US and utilising this correctly is essential in making sure that wealth passes efficiently to the next generation. We can conduct a review of your position and make recommendations, often working alongside specialist US and/or UK tax lawyers depending on complexity to give you the peace of mind that you need.

For other, non-US foreign nationals living in the UK, your domicile position will heavily affect your exposure to UK Inheritance Tax. We can conduct a review of your position and make recommendations, working with advisers in your home jurisdiction to ensure alignment between the regimes in your home country and the UK so that your wealth passes to the next generation in the way that you want it to.

Property and Capital Gains Tax

We can advise on the consequences of owning either US or UK real estate including reporting obligations with regards to rental income as well as understanding the consequences of and planning for eventual sale or inheritance.

Contact Us

For Americans living in the UK, we can help you plan for and understand the US and UK tax consequences of selling a main home taking into account the differing rules in each jurisdiction as well as foreign currency issues.

We can also provide advice around the tax consequences of owning and selling foreign investments. Both the US and the UK have punitive tax regimes upon sale for holders of certain types of non-US and non-UK investments respectively, so it is important to review your position to ensure alignment between both jurisdictions.
