Specialist UK & international tax advice
Specialist international tax accountants in the UK. We handle residency, double taxation relief, US-UK dual filing, transfer pricing & HMRC offshore…
If you earn, invest, or trade across borders and your tax structure is not watertight, you are exposed, not hypothetically, but financially.
Pearl Lemon Accountants is the international tax accountant that UK directors, shareholders, US citizens in Britain, property investors, and expanding companies rely on. We deal with cross border tax risk before it becomes a penalty, a double taxation bill, or an HMRC enquiry.
If you have overseas income, foreign subsidiaries, offshore assets, or need coordinated US UK tax support, this is not a bookkeeping task. It is a strategic financial control problem, and that is exactly what we solve.
International Tax is not about filling in extra boxes on a tax return. It is about structuring your affairs so you are not overpaying, under-reporting, or exposing yourself to avoidable compliance risk.
Our International Tax Service covers individuals and businesses across the UK who need clarity on: Tax residency and domicile. Double taxation agreements. Overseas profits and repatriation. Transfer pricing. VAT on international trade. Offshore disclosures. Dual US-UK reporting.
Below is how we address the risks that cost clients serious money.
Most cross-border problems begin with a wrong residency assumption. You either pay the UK tax on worldwide income when you did not need to, or you assume you are non-resident and HMRC disagrees. We conduct a detailed Statutory Residence Test review, including:For business owners, we assess central management and control to determine corporate residency exposure. One incorrect position can expose years of income to UK tax plus penalties. Our UK tax accountants document and support your position with evidence that stands up to scrutiny.
Paying tax twice on the same income is not a badge of compliance. It is usually a structuring failure. As a UK international tax accounting firm, we:Directors receiving overseas dividends, consultants billing foreign clients, and landlords with overseas property often overpay because relief was not claimed correctly. The UK has over 130 tax treaties. Each has specific provisions. Apply the wrong article, and HMRC can deny the claim. We ensure International Tax reporting is accurate and defensible.
If you are a US citizen living in Britain, you file to two tax authorities. Every year. Regardless of where you live. We coordinate with US tax advisors in UK networks to align:Income classification mismatches between HMRC and IRS systems create unnecessary exposure. Pension treatment, stock options, partnership income, and dividend timing must be aligned. Without coordination, you can pay more than required or trigger red flags. A US-UK tax accountant approach keeps both systems aligned and reduces overlap.
Expanding abroad without reviewing the tax structure is expensive.
We advise UK companies on: For SaaS firms expanding into the US, manufacturers opening EU operations, or consultancies billing overseas clients, profit allocation matters. Transfer of intellectual property, intercompany loans, and management charges must be structured correctly. Our Accounting & Business Advisory Services integrate tax planning with commercial growth objectives. Relocating the business or directors abroad?

If your UK company transacts with a related overseas entity, transfer pricing rules apply. This includes: HMRC requires arm’s length pricing supported by documentation. We prepare: Penalties for inadequate documentation can reach up to 30 percent of the additional tax assessed. An international tax accountant UK businesses engage must ensure pricing is commercially supportable and technically compliant.
Foreign rental income, offshore investment structures, and overseas capital gains are high-risk reporting areas.
We assess: HMRC receives automatic financial information from over 100 jurisdictions under the Common Reporting Standard. Undeclared foreign income is increasingly visible. Our UK tax accountants ensure overseas income is reported correctly and relief is claimed where available.
Cross-border sales create VAT complexity quickly.
We advise on:eCommerce and digital service providers often create VAT exposure in multiple jurisdictions without realising it.
Incorrect VAT treatment affects margins and cash flow.
Our International Tax team works with finance teams to structure compliant VAT reporting frameworks.

If HMRC opens an enquiry into overseas income or assets, timing matters.
We manage: Voluntary disclosure before HMRC contacts you typically reduces penalties significantly. Waiting reduces options. Our International Tax Service includes risk assessment and controlled disclosure planning. Already under enquiry? See our HMRC Tax Investigation Support and Offshore Tax Planning services.

International Tax is technical and enforcement-focused. It requires coordination across jurisdictions.
We combine: HMRC collected over £36 billion in compliance revenue in the 2023 to 2024 period (source: HMRC annual report), and offshore investigations continue to rise under global information sharing agreements such as the Common Reporting Standard. Cross border income is no longer invisible.
