When your U.S. and Portugal tax returns are prepared separately, the biggest risk isn’t calculation errors; it’s inconsistent facts, classifications, and treaty positions. Our coordinated return service prepares both returns together and includes a coordination memo, reducing audit risk and making future filings simpler if your situation stays the same.

Portuguese Golden Visa funds often implicate U.S. tax rules that do not arise in domestic investment reporting. Issues such as lower-tier PFIC filings, reliance on fund-provided PFIC statements, Self-Directed IRA prohibited transaction rules, and ownership through trusts or nominee structures can affect return completeness and statute-of-limitations exposure. In many cases, the consequences of early assumptions only become visible years later, typically on distribution, redemption, or audit.

Many Americans who used their self-directed IRAs to invest in Portuguese Golden Visa funds may have unknowingly triggered a prohibited transaction, exposing the entire account to U.S. tax and penalty risk. Investors who act before year-end can often reduce their exposure to a fraction of what it would be if discovered later in an IRS audit.

Many Americans moving to Portugal assume that simply adding a Portuguese will is enough, but uncoordinated cross-border documents often create more problems than they solve. We frequently see U.S. plans that don’t hold up once clients become non-residents, or Portuguese wills that accidentally trigger dual probate.

For American expat families in Portugal, not naming guardians for minor children can leave their care in the hands of local courts, often without relatives nearby to step in. A coordinated estate plan ensures your children are protected and cared for by the people you trust, without uncertainty or delay.

Congress designed the PFIC rules to discourage Americans from deferring U.S. tax through offshore funds. The result is a punitive system: instead of tax deferral, investors are either taxed annually on income they may not have received (through a Qualified Electing Fund, or QEF, election), or under a default regime that re-characterizes gains, spreads them over the holding period, and layers on an interest charge.

Many American investors assume that if a foreign fund, bank, or lawyer works with U.S. clients, they will proactively flag any U.S. tax concerns. That assumption is understandable, but it isn’t safe. Americans are subject to uniquely complex tax rules that follow them across borders, rules that do not apply to investors from most other countries. Whether or not a fund is respected, well-regulated, or fully compliant under Portuguese law says nothing about how it will be taxed by the United States.

Some U.S. investors exploring the Portuguese Golden Visa program consider using assets held in Self-Directed IRAs or Solo 401(k) plans to fund their investment. However, this approach carries significant legal and tax risk under U.S. law and may result in substantial penalties.

New U.S. tax legislation has now cleared Congress, with the One Big Beautiful Bill Act (“OBBB”) finally passed by both chambers. For Americans living in Portugal and for Portuguese residents (or entities) with U.S. income, the new law raises real concerns and some limited opportunities.

The U.S. dollar has declined more than 10% against the euro so far in 2025, reaching its weakest level in over three years. After a relatively stable period, this year has brought steep tariffs, renewed trade friction, and major European fiscal expansion, all contributing to sustained euro strength and dollar weakness.

Physical gold and other precious metals are subject to distinct tax rules in the United States and Portugal, which may affect U.S. citizens holding such assets while residing abroad.
