Introduction - Why Foreign Assets Require Special Attention When Moving to the U.S.

Relocating to the United States can create new opportunities professionally and personally. However, it also introduces a new tax and financial environment that differs significantly from many countries around the world.

Foreign nationals moving to the U.S. commonly hold:

  • foreign bank accounts,
  • pensions from previous employment,
  • brokerage accounts,
  • investment-linked insurance policies,
  • property abroad,
  • global portfolios,
  • savings plans from their home country.

Because the U.S. tax system is based on residency, not citizenship alone, individuals who become U.S. tax residents generally face:

  • U.S. taxation of worldwide income, and
  • U.S. reporting obligations for foreign financial assets.

Foreign nationals often ask:

  • “Do I need to tell the U.S. about my foreign accounts?”
  • “Will the U.S. tax my foreign pension?”
  • “What happens to investments I already own?”
  • “Do PFIC rules apply to my foreign mutual funds?”
  • “How does U.S. tax residency change things?”
  • “What about property I still own abroad?”

This guide provides an overview of how U.S. rules apply to foreign assets, pensions, and investments when an individual relocates to the United States.

This is educational information only, not legal or tax advice.

What This Guide Helps You Understand

Relocating to the United States introduces a financial and tax environment that treats foreign assets very differently from most jurisdictions.
After reading this guide, you will understand:

  • When and how U.S. tax residency begins, and why it drives all reporting obligations
  • How foreign bank accounts, brokerage accounts, pensions, and property are treated under U.S. tax rules
  • Which foreign investments may fall under PFIC rules once you become a U.S. resident
  • How rental income, dividends, pensions, and capital gains from abroad are taxed in the U.S.
  • Why foreign gifts, inheritances, and transfers may require reporting even when not taxable
  • How foreign business interests, partnerships, and corporate ownership may trigger specialized U.S. filings
  • What reporting forms apply to your foreign accounts, entities, and investments
  • How double taxation may arise and when the Foreign Tax Credit may offer relief
  • Why currency conversion, liquidity, and multi-country retirement plans require careful coordination

This guide is educational only and does not constitute personalised tax, legal, or investment advice.

U.S. Tax Residency: The Starting Point for All Foreign Asset Rules

Foreign nationals generally become U.S. tax residents when they meet one of the following:

1. Green Card Test

A lawful permanent resident is automatically treated as a U.S. tax resident.

2. Substantial Presence Test (SPT)

A foreign national generally becomes a U.S. tax resident when:

  • all days in the current year
    • one-third of days in the prior year
    • one-sixth of days in the year before that
      ≥ 183 days

3. First-Year Residency Election (in some cases)

Certain individuals may elect to be treated as U.S. residents for part of a year.

4. Treaty Tie-Breaker Rules

If an individual is considered a tax resident of two countries, income tax treaties (if applicable) may establish residency for treaty purposes.

U.S. Tax Residents Are Taxed on Worldwide Income

Once an individual becomes a U.S. tax resident, the U.S. generally taxes:

  • foreign bank interest
  • foreign dividends
  • foreign rental income
  • foreign business income
  • foreign pension income
  • foreign capital gains
  • compensation earned abroad (depending on timing)

U.S. residency does not depend on citizenship status.

This principle drives the importance of understanding how foreign assets interact with U.S. rules.

Foreign Bank Accounts and Cash Holdings

Foreign bank accounts remain fully permissible, but U.S. tax residents may need to:

  • report interest income
  • report account balances (if thresholds apply)
  • maintain records of transfers
  • file specific forms with the U.S. Treasury and IRS

Key reporting forms include:

FBAR (FinCEN Form 114)

Required if aggregate foreign account balances exceed $10,000 at any time during the year.

FATCA Form 8938

Required when foreign assets exceed certain thresholds, which depend on:

  • filing status
  • residence (inside/outside U.S.)

Foreign Brokerage Accounts and Investments

Foreign brokerage accounts may contain:

  • foreign mutual funds
  • UCITS ETFs
  • investment-linked insurance vehicles
  • foreign bonds
  • offshore portfolios
  • savings plans
  • structured products

PFIC Rules

Many non-U.S.-domiciled pooled investment vehicles may be classified as PFICs (Passive Foreign Investment Companies) under U.S. tax law.

  • PFIC reporting uses Form 8621
  • PFIC tax treatment differs from U.S.-domiciled funds
  • U.S. tax residents may face annual filing obligations
  • Suitability varies by investment structure

PFIC rules apply once an individual becomes a U.S. tax resident.

Non-residents (NRAs) generally do not face PFIC rules.

Foreign Pensions and Retirement Plans

Foreign nationals often arrive in the U.S. with foreign retirement plans such as:

  • UK pension schemes
  • Canadian RRSPs
  • Australian Superannuation
  • European occupational plans
  • Asian provident funds
  • Middle Eastern end-of-service schemes
  • Foreign personal savings plans

General U.S. treatment (high-level themes only)

  • Growth inside foreign pensions may be treated differently under U.S. rules
  • Distributions may be taxable under U.S. law
  • Treaty rules may apply depending on country
  • Employer contributions abroad may not be treated like U.S. contributions
  • Transfers from foreign pensions into U.S. plans are generally not permitted
  • End-of-service benefits vary widely in treatment

Each jurisdiction has different U.S. tax considerations.

Foreign Property and Rental Income

If you own property in your home country:

  • Rental income is generally taxable in the U.S.
  • Expenses may be deductible depending on circumstances
  • Currency conversion to USD is required
  • Capital gains on sale of the property may be taxable
  • Your home country may also tax the income

Whether double taxation relief applies depends on:

  • treaty rules
  • home country taxation
  • U.S. foreign tax credit (FTC) applicability

Foreign Business Interests

Incoming U.S. residents may hold:

  • ownership in foreign companies
  • partnerships
  • private businesses
  • offshore entities
  • professional corporations
  • LLPs

U.S. tax rules may require:

  • entity classification
  • reporting (e.g., Form 5471, 8865, 8858)
  • income inclusion rules
  • Subpart F or GILTI considerations for certain entities

Entity classification depends on facts and circumstances.

Foreign Gifts and Inheritances

Receiving foreign gifts or inheritances generally does not create income tax in the U.S., but may require reporting.

Examples:

Form 3520

For certain foreign gifts or inheritances exceeding thresholds.

Transfer from foreign trusts

May involve additional reporting.

U.S. tax residents still must track foreign transactions.

Foreign Life Insurance Policies and Investment-Linked Plans

Some foreign life insurance or savings plans include investment components.

U.S. tax considerations may include:

  • PFIC rules
  • policy classification
  • reporting requirements
  • foreign trust rules for certain structures
  • income recognition rules

Suitability depends entirely on policy structure.

Foreign Currency Considerations

Foreign assets may be denominated in:

  • EUR
  • GBP
  • AUD
  • CAD
  • SGD
  • HKD
  • CHF
  • AED
  • INR

Currency planning may influence:

  • future retirement spending
  • investment risk
  • U.S. tax reporting
  • real estate holdings
  • long-term financial projections

The U.S. requires reporting in USD, including:

  • gains
  • losses
  • interest
  • dividends
  • rental income
  • pension income

FX conversion rules apply.

Social Security and Foreign Social Systems

Foreign nationals may have:

  • home-country social contributions
  • foreign pension rights
  • global employment periods

The U.S. maintains totalization agreements with several countries, which:

  • coordinate social security taxes
  • combine work credits for benefit eligibility
  • may affect double contributions

Examples of partner countries include:

  • UK
  • Canada
  • Australia (modified),
  • many EU countries

Totalization agreements do not transfer pensions, but may influence eligibility.

Double Taxation Considerations for Foreign Assets

Double taxation may arise when:

  • the home country taxes foreign income
  • the U.S. taxes the same income
  • treaty rules do not provide relief
  • foreign tax is not creditable
  • timing of income differs between countries

Common areas:

  • rental income
  • dividends
  • capital gains
  • pensions
  • foreign business income
  • interest
  • employment income earned before arrival

The Foreign Tax Credit (FTC) may reduce overlap depending on circumstances.

Reporting Requirements for Foreign Assets

U.S. tax residents may have annual reporting requirements separate from tax calculations.

Key forms include:

1. FBAR (FinCEN Form 114)

Required if aggregate foreign bank account balances exceed $10,000.

2. FATCA Form 8938

Foreign financial assets required to be reported if thresholds are met.

3. Form 8621 (PFIC Form)

Required for many foreign pooled investment funds.

4. Form 3520 / 3520-A

Required for certain foreign trusts or foreign gifts.

5. Form 5471

For U.S. persons with certain interests in foreign corporations.

6. Form 8865

For certain foreign partnerships.

7. Form 8858

For certain foreign disregarded entities.

These forms relate to reporting, not investment recommendations.
