A U.S. corporate executive relocating abroad faces a lengthy to-do list, and tax planning should rank among the top priorities. If you remain a U.S. citizen, relocating does not end your U.S. tax obligations — it just adds a second country’s taxes on top. The increased complexity of balancing multiple tax regimes makes working with a qualified professional essential.
The key planning issues are worldwide income, foreign tax relief, payroll taxes, state residency, reporting, and — if citizenship is later relinquished — possible expatriation tax.
Worldwide Income and Foreign Tax Relief
U.S. citizens generally remain taxable on worldwide income no matter where they live, including salary, bonuses, equity compensation, investment income, and employer-paid allowances. Employer-paid tax reimbursements, housing, education, cost-of-living allowances, and similar benefits generally are included in taxable income unless a specific exclusion applies.
An executive may elect the foreign earned income exclusion (FEIE) of approximately $130,000 per tax year under IRC Section 911 if you have a foreign tax home and qualify for either the physical presence test (being physically present in foreign countries for at least 330 full days during a 12-month period) or the bona fide resident test (a bona fide resident of a foreign country for an uninterrupted period including an entire tax year). A separate housing-cost exclusion may apply to qualifying employer-provided housing costs.
The FEIE only applies to earned income and does not cover investment income, capital gains, or deferred compensation payouts. Tax rules for stock options, RSUs, and deferred compensation can be complicated, often requiring complex calculations to determine which country can tax the income and when and resulting in double taxation and mismatched timing.
If you do not elect the FEIE — or your income exceeds the FEIE —– you may be able to claim foreign tax credits (FTCs) under IRC Sections 901 and 904. FTCs are a credit for foreign income taxes paid, applied dollar-for-dollar against U.S tax on the same income, subject to certain limitations. Unused credits generally may be carried back one year and forward 10 years.
Reporting Compliance and State Residency
Foreign bank accounts and investments may trigger a Foreign Bank Account Report (FBAR) when aggregate foreign financial accounts exceed $10,000 at any time during the year, as well as Form 8938 reporting at separate, status-dependent thresholds. Ownership or control of foreign corporations, partnerships, disregarded entities, trusts, or Passive Foreign Investment Companies (PFICs) may require Forms 5471, 8865, 8858, 3520, or 8621. Failure to file can mean significant penalties and may extend the assessment period or affect foreign tax credits. Also, certain international rules like NCTI, Subpart F, and PFICs can create phantom income and punitive U.S. tax treatment.
State residency is independent of federal residency. You may remain taxable by the former state if you maintain ties there, such as a home, driver’s license, family ties, or voter registration. State treatment of the FEIE and FTC varies and must be looked at separately.
Payroll Taxes
The FEIE does not eliminate Social Security or Medicare taxes. An employee of a U.S. employer could still be subject to the Federal Insurance Contributions Act (FICA) on foreign compensation, although a Social Security totalization agreement may exist with the host country to avoid double taxation and to coordinate benefits.
Expatriation Tax
Renouncing citizenship can create a separate expatriation tax under IRC Section 877A that treats worldwide assets as sold at fair market value on the day before expatriation. This can be a massive one-time hit for someone with significant equity or deferred compensation.
Before moving abroad, work with a qualified international tax professional to model the exclusion against foreign tax credits, document travel and workdays, review payroll and totalization treatment, establish the intended state-residency position, and inventory foreign reporting obligations. Many corporate relocation packages also include tax support to help manage the added tax burden of living and working abroad.
