Five Cross-Border Wealth Mistakes High-Net-Worth Families Make

Managing wealth across borders introduces unique challenges that even experienced investors can overlook. For UK expats in the US and Americans with UK assets, avoiding these five common mistakes can protect both capital and peace of mind.

1. Failing to Coordinate Advisors

Using separate advisors in each country often leads to conflicting strategies. Coordination between tax, legal, and investment professionals is essential to avoid duplication or gaps.

2. Ignoring Currency Exposure

Exchange rate movements can erode returns if not properly managed. Diversifying holdings and considering hedging options can reduce unwanted volatility.

3. Overlooking US Tax Treatment of UK Assets

From pensions to ISAs, the US treats many UK accounts differently. What is tax-efficient in the UK may not be in the US. Understanding these differences prevents unexpected liabilities.

4. Neglecting Estate Planning Across Jurisdictions

Without coordinated estate planning, families risk exposure to both UK Inheritance Tax and US Estate Tax. A unified plan can ensure assets pass efficiently to the next generation.

After 6 April 2027, most unused pension funds and pension death benefits will be brought into the value of the deceased’s estate for UK Inheritance Tax. The nil-rate band limit is £325,000 per person (£650,000 for couples), and everything above that is taxed at 40%.

5. Waiting Too Long to Seek Cross-Border Advice

Many families delay professional advice until a triggering event occurs, such as retirement or relocation. The earlier you align your strategy, the greater your long-term flexibility.

Cross-border wealth management is complex, but with the right guidance, families can protect and grow their assets with confidence on both sides of the Atlantic.
