US and UK Tax Specialists for American Citizens

US and UK Tax Specialists for American Citizens

Living in Britain as an American offers incredible cultural experiences and professional growth — but it also brings complex tax challenges. That’s where US and UK tax specialists come in. Each year, thousands of US citizens face the same dilemma: how to stay compliant with both HMRC and the IRS without paying twice.

These cross-border experts handle international tax obligations with precision, helping expats remain fully compliant while avoiding double taxation. With the right guidance, managing taxes across two systems becomes efficient, accurate, and stress-free.

At JungleTax, we make this process simple for Americans living in the UK. Our team delivers tailored, compliant, and time-saving tax solutions designed to keep you on the right side of both UK and US tax authorities — while optimising every possible saving.

Why Americans in the UK Need Dual Tax Support

One of the few nations that bases taxes on citizenship rather than residency is the United States. This means that American citizens must file U.S. taxes annually if they reside abroad permanently. At the same time, the UK requires tax filings if you earn income or reside in the UK.

Without expert guidance, this dual obligation quickly becomes overwhelming. You may face:

  • Double taxation

  • Missed foreign tax credits

  • Confusion over reporting thresholds

  • Incorrect foreign bank account reporting (FBAR)

Specialist accountants handle both sides. US and UK tax specialists for American citizens interpret tax treaties, identify credits, and align both systems to eliminate overpayment.

Understanding the US–UK Tax Treaty

The US–UK tax treaty prevents Americans in Britain from being taxed twice on the same income. It defines how income, such as employment earnings, dividends, pensions, and rental profit, should be taxed.

However, applying the treaty requires precision. Accountants must interpret residency status, claim credits, and determine which country gets taxing rights.

A qualified cross-border tax specialist understands both the IRS and HMRC frameworks. They ensure compliance while maximising deductions under the treaty. For instance, income earned in the UK can often be offset with the Foreign Tax Credit on your US return, reducing your overall liability.

US Expat Tax Filing in the UK: Key Requirements

Filing taxes as a US expat in Britain involves several components:

  1. US Federal Tax Return (Form 1040): Mandatory for all American citizens, even those earning abroad.

  2. Foreign Bank Account Report (FBAR): Required if your combined foreign accounts exceed $10,000 at any time during the year.

  3. FATCA Reporting (Form 8938): Applicable for higher balances in overseas accounts or investments.

  4. UK Self Assessment: Required if you earn self-employment income, rental income, or have complex financial arrangements.

A US and UK tax specialist for American citizens ensures all these filings align ideally — avoiding costly errors, late penalties, or missing declarations.

Dual Taxation Advice for Americans in the UK

Dual taxation can feel unfair — but the right strategy turns it into an opportunity. US expats can use the Foreign Earned Income Exclusion (FEIE) to exclude up to $126,500 (2024 threshold) of UK income from US tax. They can also claim the Foreign Tax Credit for taxes already paid in the UK.

Choosing the correct approach depends on personal circumstances. For example, if you have dependents, property income, or dual income streams, a dual taxation adviser tailors a plan to ensure you never pay more than necessary.

This is where specialists like JungleTax excel — our team manages both jurisdictions seamlessly, protecting clients from double taxation while keeping every report 100% compliant.

The Role of US Tax Accountants in London

With many American professionals working in London’s financial, creative, and tech sectors, demand for US tax accountants in London has skyrocketed. These experts act as the link between two complex tax systems.

A local tax specialist has an in-depth understanding of UK tax laws and coordinates with IRS requirements. They help clients claim treaty benefits, report international investments, and manage pension schemes such as SIPPs or 4vers accurately.

At JungleTax, our cross-border team provides personalised consultations for US expats in London and across the UK. We ensure filings are accurate, efficient, and submitted on time.

Common Tax Mistakes American Expats Make

Even financially savvy expats make costly tax mistakes without professional support. Common errors include:

  • Failing to file US tax returns while abroad

  • Ignoring the UK Self Assessment when freelancing or renting property

  • Missing FBAR or FATCA deadlines

  • Misreporting dual income or pensions

  • Failing to claim tax treaty exemptions

US and UK tax specialists for American citizens correct these issues and prevent future ones. They track reporting thresholds, currency conversions, and tax year differences between the US (calendar year) and the UK (April to April).

This precision ensures every return aligns perfectly, avoiding penalties or audits from either side.
