A practical guide explaining how US tax rules apply to foreign business ownership for expats and international entrepreneurs, including income attribution, reporting obligations, and planning considerations.
This is a div block with a Webflow interaction that will be triggered when the heading is in the view.
For globally mobile Americans, currency is often treated as background noise.
Income arrives in one currency.
Investments are held in another.
Spending happens somewhere else entirely.
For years, nothing seems wrong.
Then reality shows up:
Currency is not a tactical decision.
It is a structural force that affects almost every long-term financial outcome for people living internationally.
Unlike investment markets, currency risk is:
This guide explains how multi-currency exposure works in a cross-border life, focusing on:
This article is educational only. It does not provide personalised investment advice. Outcomes depend entirely on individual circumstances.
This article is designed for:
Specifically, it helps explain:
We’ll start with the basic reality most people underestimate.
You do not need to speculate in currencies to be exposed to them.
Currency risk exists whenever:
This applies to:
Currency exposure is a by-product of geography, not investment strategy.
One of the most common mismatches occurs between:
Examples:
When exchange rates move:
This is not a market issue - it is a cash-flow issue.
People often say:
“I earn in a strong currency.”
But “strong” is always relative:
A strong income currency today may:
Income strength must be evaluated in context, not isolation.
Many people assume:
“If my portfolio is invested globally, I’m diversified from currency risk.”
This is only partially true.
Portfolio currency exposure depends on:
A globally diversified portfolio can still create concentrated currency risk at the point of spending.
For Americans, USD naturally becomes the default:
However:
USD dominance simplifies reporting, but it does not automatically solve currency alignment.
Currency matters most when:
During accumulation years:
During retirement:
This is why currency planning is fundamentally retirement planning, not trading.

Most people have:
A strategy does not mean:
It means:
Currency planning is about alignment, not optimisation.
Currency sensitivity changes over time.
Typical phases include:
Each phase:
Applying the same currency assumptions across all stages rarely works.
Currency is not just an investment issue.
It interacts with:
A gain in local currency can still produce:
This is why currency planning cannot be separated from tax awareness.
Most people realise currency matters when:
At that point:
Early awareness does not eliminate currency risk - it makes it manageable.
For US citizens living overseas, currency exposure often develops in layers.
Common patterns include:
This layering creates structural currency mismatch, even when nothing feels wrong day to day.
Over time:
The issue is rarely obvious in annual statements. It shows up in real life.
Foreign nationals moving to the US often experience the reverse problem.
Before the move:
After the move:
This can result in:
Inbound expats often underestimate how much their financial picture is reframed on entry.
Property is one of the clearest examples of currency risk.
Foreign property owners may:
Currency movements can:
Property decisions made years earlier can carry unintended currency consequences later.

Pensions and retirement accounts introduce long-duration currency exposure.
Examples:
When retirement spending occurs in a different currency:
This is why retirement planning across borders is inseparable from currency planning.
Currency movements affect capital gains in ways many people do not anticipate.
For US tax purposes:
This means:
Currency effects can create tax outcomes that feel disconnected from investment reality.
Currency hedging is frequently misunderstood as:
In reality:
However:
The question is not “should I hedge?”
It is “which risks matter, and when?”
Currency sensitivity differs by horizon.
Short-term
Long-term
Confusing short-term currency needs with long-term investment exposure leads to poor decisions.
Currency risk is not just mathematical.
It is behavioural.
Common reactions include:
These reactions often do more damage than the currency movement itself.
No one can reliably predict exchange rates over long periods.
Effective multi-currency planning focuses on:
Alignment reduces stress even when markets are volatile.
Currency planning is often skipped because:
But for globally mobile individuals, currency is one of the largest silent drivers of outcomes.

Any recommendations depend entirely on individual circumstances.
If your financial life spans more than one country, currency exposure is already part of your reality - whether you actively manage it or not.
Understanding how currency affects income, assets, and spending can help reduce surprises and improve long-term clarity.

Yes. Currency risk exists whenever income, assets, or spending occur in different currencies. It is a by-product of living internationally, not an investment choice.
During retirement, income is often fixed and spending becomes predictable. Currency movements directly affect purchasing power, making alignment more important than during accumulation years.
Not necessarily. Portfolio diversification does not automatically align assets with future spending currency. Currency risk often shows up at the point withdrawals are made.
For US purposes, gains are calculated in USD. Currency movements can create taxable gains or losses even when asset values appear unchanged locally.
Hedging is not always necessary or appropriate. Effective planning focuses on understanding which currencies matter, when they matter, and how exposure changes over time.
