Introduction: Why PE Professionals Need the US Tax Amnesty Program for Americans Abroad
American private equity professionals working in London face the most complex cross-border tax reporting of any expat group — and the penalties for getting it wrong are catastrophic. Carried interest distributions, management company profits, co-investment gains, and fund partnership interests each create separate US reporting obligations that most PE professionals overlook entirely because their UK tax advisers lack knowledge of US partnership reporting rules. The US Tax Amnesty Program for Americans Abroad provides critical relief for PE professionals who have accumulated a compliance gap. Still, the window closes the moment the IRS detects the non-compliance through automatic information exchange.
We recently completed a Streamlined Filing for Marcus (name changed), an American partner at a London-based PE fund who had received carried interest distributions totaling approximately 1.2 million pounds over five years without filing US returns, FBARs, or Form 8865 foreign partnership returns. His combined penalty exposure exceeded three hundred and twenty thousand pounds — FBAR penalties on nine accounts, failure-to-file penalties for five years of missed returns, Form 8865 penalties at ten thousand dollars per form per year, and accuracy penalties on unreported carried interest income. Our US Tax Amnesty Program for Americans Abroad team eliminated every pound through proper Streamlined Filing with coordinated FTC claims that credited UK CGT paid on carried interest against US liability. His net US tax across three covered years was approximately eight thousand pounds. Professional fees: fourteen thousand pounds. Our specialist PE compliance team handles these complex cases regularly.
How Carried Interest Creates a US Tax Amnesty Program for Americans Abroad Exposure
Section 1061 and the Three-Year Holding Period
Under Section 1061, carried interest gains qualify for long-term capital gains treatment only if the underlying assets have been held for more than three years — not the standard one-year holding period that applies to other capital gains. Gains on assets held for one to three years are recharacterized as short-term capital gains, taxed at ordinary income rates up to 37%. This creates a uniquely punitive regime for PE professionals whose funds typically hold investments for two to five years, meaning a substantial portion of carried interest may be taxed at ordinary rates. IRS guidance on Section 1061 continues to evolve.
Form 8865 Foreign Partnership Reporting
Every American who is a partner in a foreign partnership — which includes virtually every UK-based PE fund structure — must file Form 8865 annually if they meet certain ownership or contribution thresholds. The penalty for failing to file Form 8865 is $10,000 per form per year, with an additional penalty of $10,000 per month (up to $50,000) if the failure continues after IRS notification. For a PE professional who has missed Form 8865 for five years, the penalty exposure on this single form alone exceeds fifty thousand dollars before any other penalties are considered. The US Tax Amnesty Program for Americans Abroad eliminates these penalties for qualifying overseas filers. The ICAEW publishes cross-border partnership guidance.
The Cross-Border Carried Interest Tax Maze
UK CGT on Carried Interest at 28%
The UK taxes carried interest at a special CGT rate of 28% — higher than the standard 20% CGT rate for most other gains. This rate applies regardless of how long the underlying fund assets were held. On a carried interest distribution of five hundred thousand pounds, UK CGT at 28% produces a tax of one hundred and forty thousand pounds. The same distribution also triggers US taxation, creating the double-taxation problem that only a proper US Tax Amnesty Program for Americans Abroad coordination can resolve through Foreign Tax Credit claims. HMRC administers UK carried interest taxation.
FTC Coordination That Eliminates Double Taxation on Carry
When UK CGT at 28% exceeds the US tax rate on the same carried interest (23.8% for long-term gains or 37% for short-term gains under Section 1061), the excess UK tax generates a Foreign Tax Credit carryforward usable against future US tax for up to ten years. However, the FTC calculation must account for the different holding-period rules (the UK has no equivalent of Section 1061’s three-year requirement), different tax-year timing (UK April-April versus US January-December), and currency conversion between sterling and dollar amounts. Our US Tax Amnesty Program for Americans Abroad team accurately performs these parallel calculations. Investopedia provides context on cross-border credit reporting, and FinCEN covers FBAR requirements for fund accounts.
Case Study: Three Hundred and Twenty Thousand Pounds in PE Penalties Eliminated
Marcus’s Fund Structure and Income
Marcus was a partner in a London-based mid-market PE fund with approximately 1.8 billion pounds under management. His carried interest participation entitled him to approximately 1.5% of fund profits, resulting in distributions averaging 240,000 pounds per year across five fund exits over the period 2019-2024. He held nine UK financial accounts, including his personal and joint current accounts, two savings accounts, an ISA, a workplace pension, a SIPP, and two investment accounts. His aggregate foreign account balances exceeded 720,000 pounds.
The Penalty Calculation
FBAR penalties (post-Bittner): five years at approximately sixteen thousand five hundred dollars per year equals eighty-two thousand five hundred dollars (sixty-five thousand pounds). Form 8865 penalties: five years at ten thousand dollars per year equals fifty thousand dollars (forty thousand pounds). Failure-to-file penalties on five years of missed returns with substantial unreported income: approximately one hundred and twenty thousand dollars (ninety-five thousand pounds). Accuracy penalties at 20% on unreported carried interest: approximately ninety-six thousand dollars (seventy-six thousand pounds). Form 8621 PFIC penalties for ISA holdings: approximately thirty thousand dollars (twenty-four thousand pounds). Conservative total: three hundred and twenty thousand pounds.
The Resolution
Our team prepared three years of 1040s with Schedule D and Form 8949 for carried interest gains, properly sourced between the US and UK based on where fund management activities occurred during each holding period. FTC optimization credited UK CGT at 28% against the US liability, eliminating US tax on most of the carried interest and generating an excess FTC carryforward. We filed five years of FBARs, three years of Form 8865, and corrected PFIC reporting for his ISA holdings. The non-willful certification documented his employer’s complete absence of US tax briefings and his genuine belief that UK Self Assessment satisfied all obligations. Result: zero penalties, net US tax of eight thousand pounds across three years, and restructured investments eliminating ongoing PFIC exposure. Our streamlined program handled the entire submission. MoneyHelper, the US State Department, The Balance, the AICPA, and the CIOT provide resources and standards.

American PE professionals in London face the highest penalty exposure of any expat group because carried interest, fund partnership interests, and multiple accounts create compounding obligations that multiply penalties across forms and years.
