Ahead of Year-End: Tax Efficiency Strategies for US Citizens Living in the UK

Written by Emma James, CWM

As the end of the US tax year approaches, high-net-worth individuals have the opportunity to proactively manage their wealth and enhance tax efficiency across multiple jurisdictions. With complex financial portfolios, international assets, and varying tax obligations, it’s crucial to act before the year concludes to reduce liabilities and maximise tax savings. This article outlines key strategies for managing capital gains tax, inheritance planning, residency considerations, and cross-border wealth management, tailored for both UK and US tax systems.

1. End-of-Year Tax Planning for Maximum Efficiency

With the US tax year drawing to a close, there are several actions you can take to optimise your tax position:

• Maximising Allowances: Make sure you utilise your full annual gifting and pension contribution allowances. For those with dual taxation exposure in both the US and UK, taking full advantage of these allowances can significantly reduce your tax liabilities.
• Tax Loss Harvesting and Strategic Gifting: Consider realising losses on underperforming assets to offset gains and reduce your overall capital gains tax burden. If you have appreciated assets, strategic gifting to family members in lower tax brackets can help further minimise taxes.
• Income Review: Review your year-to-date income, gains, and dividends to ensure they align with your long-term tax goals. Taking action now can help minimise exposure to higher tax rates before the year-end.

2. Managing Capital Gains Tax (CGT)

Capital gains tax (CGT) can be a significant burden, especially for those with appreciating global assets. As the end of the year approaches, consider these strategies to reduce CGT exposure:

• Staggered Asset Sales: To manage CGT, consider spreading the sale of high-value assets across multiple years. In the UK, CGT rates are 18% for basic-rate taxpayers and 24% for higher-rate taxpayers, with a reduced annual exemption of £3,000.
• International Tax Planning: If you hold assets in different jurisdictions, coordinate the timing of sales in countries with lower CGT rates to optimise your tax outcome.
• Tax Loss Harvesting: If you have investments that have underperformed, realising those losses can offset your gains and reduce your total CGT liability for the year.

3. Strategic Inheritance Tax and Trust Planning

With the tax year ending, it’s essential to review your inheritance tax (IHT) planning and trust structures. Changes to UK IHT laws, especially concerning non-domiciled individuals, mean this is the perfect time to act:

• Reviewing Trusts and Gifting: With Excluded Property Trusts (EPTs) being phased out in the UK after 2024, it’s crucial to evaluate your trust structures. If you plan to gift assets, make use of the annual exemption to reduce the taxable value of your estate.
• Lifetime Gifting: Consider making gifts before the year-end to reduce the value of your estate and potentially lower future IHT liabilities.

4. Navigating Residency-Based Tax Regimes

For those with international residency or domicile issues, understanding the tax implications of your residency status is essential as the year concludes:

• UK Residents: With the non-domiciled tax regime ending in 2025, UK residents need to prepare for the taxation of their worldwide income. This is a good time to evaluate whether changing your residency or domicile could better align with your long-term tax goals.
• US Expats: US citizens are taxed on global income regardless of residency. If you’re living abroad, it’s important to review how your global assets and income are structured to avoid unnecessary taxation.
• Strategic Relocation: If you are planning to move abroad or return to the UK, consider the tax consequences. For example, if leaving the UK, your global assets could be subject to IHT for up to 10 years due to the “tail effect.” For those returning, transitional relief can allow foreign income to be excluded from UK tax for the first four years of return.

5. Cross-Border Asset Allocation Considerations for US Citizens

If you are a US expatriate, managing your wealth across multiple tax systems can be particularly challenging. Here are strategies to consider as the year-end approaches:

• Avoiding PFIC Tax Burdens: If you hold foreign mutual funds, be mindful of Passive Foreign Investment Company (PFIC) rules, which can create substantial tax burdens. Consider moving to US-domiciled investments or equities, which are not subject to PFIC rules.
• Maximising Tax-Deferred Accounts: Roth IRAs provide an excellent opportunity to grow your wealth tax-free. As a US expat, this account can help you sidestep certain foreign tax complexities, and it offers advantages under tax treaties, including with the UK.
• Currency Diversification: Consider the impact of foreign exchange risk when managing your investments. Balancing your portfolio with assets in the same currency as your future liabilities can help mitigate FX risks and protect your wealth over the long term.

Conclusion: Proactive Planning for Global Tax Efficiency

As the year draws to a close, taking proactive steps in managing your wealth across different tax jurisdictions can significantly reduce your tax liabilities. By reviewing your capital gains, inheritance plans, residency status, and cross-border investments, you can optimise your tax efficiency before the year ends.

With careful planning and timely action, you can ensure that your wealth is structured efficiently for the long term, minimising taxes and maximising the preservation of assets for future generations. Taking control of your tax strategy ahead of the year-end provides a unique opportunity to align your financial plans with your broader goals.
