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 many people, retirement planning in the US is synonymous with a 401(k).
But a significant number of internationally mobile professionals never had one.
Instead, they participated in:
These plans are often well-structured while someone lives and works in the US
The complications appear later - usually after moving abroad.
Expats with 403(b) or 457 plans often discover that:
Because these plans are less common, they are also less clearly explained, and many expats assume the same rules apply as a 401(k).
They don’t.
This guide explains how 403(b) and 457 plans work in an international context, including:
This article is educational only. It does not provide personalised financial or tax advice. Outcomes depend on individual plan documents, residency status, and circumstances.
This article is designed for:
Specifically, it helps explain:
We’ll start by clarifying the plan types themselves.
A 403(b) plan is a tax-advantaged retirement plan offered by:
At a high level:
From a tax perspective, 403(b) plans are often similar to 401(k)s - but operationally, they can differ significantly.
A 457 plan is a deferred compensation plan available to:
There are two very different types:
457(b) Governmental Plans
Offered by:
These plans:
457(b) Non-Governmental Plans
Offered by:
These plans:
This distinction becomes critical once someone leaves the US
For expats, the key issue is not contribution mechanics - it is post-employment access.
Differences may include:
Assuming “it works like a 401(k)” is often where problems begin.

Once employment ends:
403(b) plans
Often allow:
However:
457 plans
Behave differently depending on type:
This distinction matters enormously for expats.
403(b) rollovers
Often permitted to:
457(b) governmental rollovers
Often permitted to:
457(b) non-governmental plans
Often cannot be rolled into IRAs or 401(k)s.
Instead:
This is one of the most important planning differences.
For expats:
Living abroad does not change the fundamental character of the income.
Early withdrawal rules depend on:
Important nuance:
Expats often assume foreign residency changes penalties - it does not.
As with 401(k)s:
These are not IRS rules - but they often define what is practically possible.
Government plans often:
For internationally mobile public-sector professionals, these plans deserve separate analysis, not assumptions.
403(b) and 457 plans are often:
But once residency changes, these plans can become:
Understanding their rules early prevents problems later.
{{INSET-CTA-2}}
Once someone with a 403(b) or 457 plan lives outside the United States, the tax character of distributions does not change, even though residency does.
Key principle:
For US citizens
For non-resident aliens
Living abroad does not convert these distributions into foreign income.
Withholding is one of the most immediate and practical issues expats encounter.
For non-resident aliens:
Important nuance:
This can affect short-term cash-flow planning.
Holding or distributing from a 403(b) or 457 plan abroad often triggers:
In addition:
Reporting obligations resume or continue regardless of residence.
Many older 403(b) plans are annuity-based, not mutual-fund-based.
These plans may involve:
For expats, annuity-based 403(b)s can be particularly challenging because:
Treating these like a modern 401(k) is often incorrect.
Non-governmental 457(b) plans behave very differently from other retirement accounts.
Key characteristics:
For expats:
These plans require extra caution, especially when someone leaves the US
Governmental 457(b) plans generally offer:
However:
Even “better” plans can create complexity abroad.
Some recurring issues include:
Most of these issues are avoidable with early awareness.
403(b) and 457 plans:
For expats, they should be reviewed on their own terms, not as part of a generic retirement bucket.
Leaving these plans untouched for years may seem harmless.
But over time:
Once a distribution or rollover is needed, flexibility may be reduced.
For expats with 403(b) or 457 plans:
These plans reward preparation, not reaction.

Scenario 2 - Government Employee With a 457(b) Returning Home
A public-sector employee leaves the US and later accesses a governmental 457(b) plan.
Key considerations:

A non-profit executive leaves the US with a non-governmental 457 plan.
Key considerations:
Scenario 4 - Legacy 403(b) With Annuity Contract

Before making assumptions about access or rollovers, individuals may wish to review:

Not exactly. While tax treatment may be similar, access, rollover options, and provider restrictions can differ significantly, especially for older or annuity-based 403(b) plans.
Governmental 457(b) plans are typically held in trust and often allow rollovers. Non-governmental 457 plans usually cannot be rolled over and remain tied to the employer’s financial stability.
It depends on the plan type and documents. Many 403(b) and governmental 457(b) plans allow rollovers, while non-governmental 457 plans often do not.
No. These plans remain US retirement arrangements. Distributions are generally treated as US-source income and taxed under US rules regardless of residence.
