Where are you in your international journey?
Your tax considerations depend on when you are moving, where you live, how you earn, and which financial interests you maintain.

Where you land changes the answer: local rates decide the election, and some choices are only cheap before you go.

International tax complexity rarely comes from one rule.
It comes from several systems overlapping at once.
You may live in one country, remain taxable in the United States, maintain ties to a former state, earn through a business, hold foreign accounts, contribute to a local pension, and invest through platforms never designed for U.S. taxpayers.
A tax return records those facts. A tax strategy helps you understand how they work together.

At Western European rates, the credit usually beats the exclusion.
Portugal, France, Germany, and Canada tend toward the foreign tax credit; zero-tax and low-tax bases tend toward the exclusion. That is the pattern, not a rule — so give me your numbers for the directional read, and I model both elections on your actual return before anything gets filed. The election is the strategy.
Everything here is computed in your browser. Your income and foreign tax never leave this page and are never sent to me.
What this ignores. This is a directional indication, never a determination. It doesn't account for the foreign housing exclusion, the§911(f) stacking rule (excluded income still pushes your remaining income into higher brackets), state tax, self-employment tax, the FEIE's effect on the Child Tax Credit and IRA eligibility, or that the FEIE and the foreign tax credit can becombined on one return. The real answer comes from running the actual return both ways.

The FEIE-vs-FTC call compounds over years and is hard to reverse. I model it on your real numbers.

Portugal
The credit usually beats the exclusion at Portuguese rates. NHR is closed to new applicants — the successor regime (IFICI) covers qualifying professional income but not pensions, so the planning that worked in 2022 doesn’t transfer. The recurring issue I see: Golden Visa fund subscriptions signed without anyone flagging PFIC, and unipessoal Lda structures left on the default classification. Both are cheapest to fix early, and one of them is fixable only early.
Mexico
No totalization agreement — the single most expensive surprise for self-employed Americans in Mexico, because U.S. self-employment tax applies in full regardless of the exclusion. The good news is structural: the fideicomiso that holds your coastal property is not a foreign trust to the IRS, so the reporting scare stories about it are wrong. Residency under Mexico’s center-of-vital-interests test deserves attention before you trigger it, not after.
Canada
A credit country almost every time — Canadian rates generate excess credits that carry forward. The traps are account-level: the TFSA is tax-free in Canada and fully taxable in the U.S., Canadian mutual funds and ETFs are PFICs even inside a TFSA, while the RRSP enjoys treaty protection. Same investor, three accounts, three completely different U.S. answers — which is the whole argument for deciding account structure deliberately.
Work for yourself abroad and two systems claim you at once. Portugal and Canada: one social system, with a certificate. Mexico: no agreement — the full 15.3% U.S. self-employment tax applies, and the exclusion doesn’t touch it. The penalties for guessing wrong on entity classification start at five figures per form, per year, so the structure gets decided deliberately, once — not discovered at filing time.

Frequently asked questions
Clear answers to the first questions Americans abroad ask.
Do Americans living abroad still have to file U.S. tax returns?
U.S. citizens and many green card holders generally remain subject to U.S. filing rules while living abroad. The exact requirements depend on income, filing status, accounts, entities, investments, and other facts.
Will the Foreign Earned Income Exclusion eliminate all of my U.S. tax?
Not necessarily. Eligibility, income type, housing costs, self-employment tax, investment income, refundable credits, and future planning may affect the result.
Is the Foreign Tax Credit better than the Foreign Earned Income Exclusion?
There is a pattern: at Western European and Canadian rates the credit usually wins, because those rates generate excess credits that carry forward; in zero-tax and low-tax countries the exclusion usually wins. That is a starting point, not your answer — income type, housing costs, self-employment tax, and future plans all move it, and the election is hard to reverse. I model both paths on your actual numbers before electing anything.
Do I need to report foreign bank accounts if they earn little interest?
Possibly. Some foreign-account reporting requirements are based on account values, ownership, or signature authority rather than taxable income.
What happens if I have not filed U.S. returns for several years?
The response depends on filing history, tax owed, foreign-account reporting, willfulness, missing information returns, and whether the IRS has already contacted you.
Can TaxSpectra help before I move abroad?
Yes. Pre-move planning is often the best time to address state domicile, compensation, business structure, investments, retirement accounts, banking, timing, and documentation.
Does TaxSpectra provide foreign-country tax advice?
TaxSpectra focuses on U.S. tax matters. When local-country advice is needed, the engagement may require coordination with a qualified professional in that country.
Are foreign mutual funds really a problem?
Usually, yes. Most non-U.S. funds — including Golden Visa funds and ordinary European ETFs — are PFICs, with a punitive default regime and a narrow election window. The fix is structural: choose the wrapper before you invest, or act in the first year if you already have.
I’m self-employed abroad — do I owe U.S. Social Security too?
It depends entirely on whether your country has a totalization agreement. Portugal and Canada: one system, with a certificate. Mexico and many others: both systems, and the exclusion doesn’t reduce it. This is the most commonly missed five-figure item in expat returns.
Does Portugal’s NHR (or IFICI) change my U.S. taxes?
Not directly — the U.S. taxes you regardless of Portuguese incentives. What it changes is the interaction: a low Portuguese rate means less foreign tax to credit, which can shift the FEIE/FTC answer and leave U.S. residual tax where none was expected. The two systems have to be planned together.
