Every cross-border decision an American abroad faces.
Any taxable event where the IRS and your country of residence both want a piece — and where timing or structuring, decided in advance, can save you thousands.
Equity compensation
RSUs, ISOs, NSOs and ESPPs — exercise timing, vesting across borders, AMT exposure and treaty relief so the same shares aren't taxed twice.
Property sales & rental
Selling or letting property at home or abroad — capital gains exclusions, foreign tax credits, currency conversion on the gain, and how both tax systems interact.
Tax residency & relocation
Moving countries, split-year treatment, residency tie-breakers and special expat regimes (30% ruling, Beckham law, FIG) — what each move means for your US position.
Foreign income: FEIE vs FTC
The exclusion-vs-credit election is semi-irrevocable and the right answer depends on your country's tax rate. We model both and tell you which saves more, in writing.
Foreign pensions & savings
Workplace schemes, provident funds (CPF, MPF), and government plans — what the US taxes, what it doesn't, and what needs reporting either way.
PFICs & investment accounts
Local funds and tax-advantaged wrappers are rarely tax-free for US persons — most are PFICs. Advice on what to hold, what to sell, and how to unwind cleanly.
Retirement & Roth planning
Cross-border pension withdrawals, Roth conversions while abroad, and sequencing retirement income across two systems.
Company exits & business income
M&A proceeds, earnouts, LLC and K-1 income, local company structures — coordinated treatment on both sides before you sign.
Low-tax country planning
In Singapore, Dubai or Hong Kong you genuinely owe US tax each year — FEIE elections, housing exclusion and timing decisions change the number materially.

LinkedInQuestions Americans abroad ask us.
The decisions are stressful. The answers usually aren't — once someone runs the numbers on both sides.
What exactly do I get?
A written advisory memo analyzing your specific situation: the numbers under each scenario, the treaty positions that apply (where your country has one), IRS references, and a step-by-step action plan with deadlines. It's a document you can act on, share with your employer or lawyer, and keep on file.
How much does a memo cost?
Every memo is priced to its scope, quoted as a fixed fee on the free intro call before you commit to anything. No hourly billing, no surprise add-ons — you know the exact price before you pay, and it's typically a fraction of what Big-4 or specialist expat firms charge for the same analysis.
Do you cover my country?
The markets we work with most are listed above — across Europe, the Middle East and Asia-Pacific. If yours isn't listed, ask on the intro call: the US side of the analysis is universal, and we'll tell you honestly whether we can cover the local side too.
How fast will I have it?
Most memos are delivered within days of scoping, not weeks. If you're up against a deadline — an exercise window, a completion date, a move — tell us on the call and we'll confirm timing before you pay.
Why do I need this before I act, rather than at filing time?
Because most cross-border tax outcomes are locked in by the transaction itself, not the filing. Once you've exercised the options, sold the property, or triggered the residency change, your preparer can only report what happened. The memo exists so you choose the better-taxed path while you still can.
I live in a country with no US tax treaty — does advice still help?
Even more. In Singapore, Hong Kong or the UAE there's no treaty safety net, local tax is low or zero, and you genuinely owe US tax on income above the exclusion. That's exactly where elections, housing exclusion, and timing decisions — made in advance — change what you pay.
Can you also file my return?
Yes. Filing is a separate fixed-fee service ($500 simple / $950 advanced), and many advice clients have us implement the memo at filing time. But the memo stands alone — you can take it to any preparer.
