Advice to overseas nationals with UK interests under resident & non-dom regimes

Much of our day-to-day work is helping overseas nationals manage their UK tax affairs. Most of our clients have an international element — they have relocated to the UK but retained property, investments or business interests overseas. We specialise in guiding them through the UK’s resident and non-domiciled (“non-dom”) regimes, ensuring compliance and efficient planning.
At Britannia Advisory Ltd, our team of Chartered Tax Advisers provides:
Preparation and filing of UK self-assessment tax returns.
Advice on the resident and non-dom regimes, including remittance basis planning.
Assistance with the tax treatment of overseas property, investments and businesses.
Relief planning under double tax treaties.
Ongoing tax planning for UK income tax, CGT and IHT.
Support with HMRC investigations, enquiries and voluntary disclosures.
Advice on the interaction of UK and overseas rules.
This is the routine personal tax work we handle every day. Our international outlook, multilingual capability and experience with cross-border issues make us particularly suited to advising internationally mobile individuals.
Important Note
Britannia Advisory Ltd is fully authorised to provide UK tax compliance and planning services. We specialise in tax returns and advisory work for overseas nationals with UK interests, particularly under the resident and non-dom regimes. We also assist clients with HMRC enquiries and disclosures. We do not provide regulated legal services, and where legal input is required, we introduce clients to trusted, regulated law firms.
