US citizen holding non-US investments
A US citizen living abroad can build a perfectly normal local investment portfolio that creates very different consequences under the US tax system.
Local mutual funds, collective investments, insurance-based products, pensions and other investment structures may need to be reviewed from both the local and US perspectives.
Josh Clancey works alongside US CPAs, tax advisers and other professionals where a US citizen's non-US investments create wider financial-planning decisions around tax, portfolio construction, retirement and long-term wealth.
Local suitability and US tax efficiency are not the same thing
A product can be mainstream and tax-efficient in the client's country of residence while creating significant complexity for a US taxpayer.
The review may need to consider:
- non-US mutual funds
- collective investment schemes
- ETFs
- locally issued insurance or investment bonds
- offshore investment structures
- employer plans
- local retirement arrangements
- brokerage accounts
- children's investments
- trust-held investments
The relevant US tax adviser should establish the reporting and tax treatment.
Financial planning can then consider whether the portfolio remains suitable once both jurisdictions are taken into account.

Common planning areas for US citizens with non-US investments
PFIC exposure
Many non-US pooled investments can potentially fall within the Passive Foreign Investment Company rules.
That can create additional tax reporting and potentially unfavourable US tax treatment.
Local investment wrappers
A locally tax-advantaged account may not receive equivalent treatment under US tax rules.
The wrapper and the investments inside it therefore need separate analysis.
Non-US brokerage accounts
A US citizen may hold locally domiciled securities through a non-US platform.
The investment structure needs to be reviewed alongside US reporting and tax obligations.
Retirement planning
Non-US investments may form part of a wider retirement position involving 401(k)s, IRAs, overseas pensions and state benefits.
Moving country
An investment structure established in one jurisdiction may become inefficient or impractical when the client relocates again.
Mixed US and non-US families
A US citizen may share financial objectives with a non-US spouse who is not subject to the same tax and reporting system.
Questions to ask when reviewing non-US investments
Is the client a US citizen or otherwise subject to US worldwide taxation?
That determines whether US tax analysis is required alongside local-country advice.
What exactly does the client own?
The legal and tax classification of the investment matters more than the marketing name.
Are any holdings pooled non-US investments?
These may require PFIC analysis by the US tax adviser.
Does the local tax wrapper receive recognition in the US?
The answer should never be assumed simply because the product is tax-efficient locally.
Are there existing unrealised gains?
This can affect the practical consequences of restructuring.
Does the client expect to move country again?
Future residence should be considered before making long-term changes.
Is the spouse also a US person?
Different tax statuses within the same household can affect ownership and investment planning.

PFIC exposure is often discovered after the investment has already been made
A US citizen living abroad may be offered a local fund, investment account or savings product without anyone involved recognising the US implications.
The investment may be entirely conventional in the local market.
The problem is that the US tax classification can be very different.
Where a holding falls within the PFIC regime, the client may face:
- Form 8621 reporting
- additional tax calculations
- potentially unfavourable taxation
- increased professional fees
- greater complexity when selling or restructuring
The US tax adviser should determine whether a specific holding is a PFIC and advise on the tax consequences.
Financial planning can then consider whether the investment should be retained, restructured or replaced.

The solution is not simply to make every investment US-based
Cross-border investment planning should not be reduced to a single rule.
The client's portfolio still needs to reflect:
- country of residence
- regulatory access
- tax treatment
- investment costs
- diversification
- currency
- retirement objectives
- liquidity
- future mobility
- family circumstances
For a US-connected client, the objective is to find an investment structure that works across the relevant jurisdictions rather than optimising for one tax system while ignoring everything else.
This may require coordination between:
- the US CPA or tax adviser
- local tax advisers
- financial planners
- custodians
- estate-planning professionals
Josh's role is to translate the resulting tax and legal parameters into a coherent investment and financial plan.

When should the referral happen?
A referral can be useful where the client:
is a US citizen living outside the US
holds non-US mutual funds or collective investments
has been advised to buy a locally tax-efficient investment
has existing offshore investments
is unsure whether investments are PFICs
is moving between countries
has a non-US spouse
needs to redesign a portfolio around US tax constraints
Have a US citizen with non-US investments?
If a client holds foreign funds, locally tax-advantaged investments or other non-US assets that may create US tax or reporting complications, an initial discussion can help establish where financial planning should sit alongside the specialist US tax advice.
