Support With Foreign Income in the USA

In the United States, “support with foreign income” generally arises when a person’s income is earned, received, or maintained outside the United States but must be considered for child support, spousal support/alimony, financial disclosure, or taxation.

1. Foreign income can be relevant to support obligations

For family-law purposes, a U.S. court generally looks at the parent's or spouse's actual financial resources and ability to pay, rather than simply where the income is earned.

Foreign-source income may therefore be relevant when calculating:

• Child support
• Spousal support/alimony
• Modification of an existing support order
• Imputation of income where a person understates earnings
• Enforcement of support obligations
• Financial disclosures in divorce proceedings

The precise treatment depends heavily on the state's child-support and family-law statutes.

2. Foreign salary and business income

Income earned from employment abroad can be considered income even when:

• the employer is outside the United States;
• the salary is deposited into a foreign bank account;
• the person is paid in a foreign currency; or
• the person claims a foreign tax exclusion.

For U.S. federal tax purposes, U.S. citizens and resident aliens generally remain subject to U.S. taxation on worldwide income.

Importantly, the IRS distinguishes foreign earned income from investment income. Wages, salaries and professional fees for services performed abroad can constitute foreign earned income, while dividends, interest and capital gains generally do not.

3. Foreign Earned Income Exclusion does not necessarily eliminate income for support purposes

A person working abroad may qualify for the Foreign Earned Income Exclusion (FEIE) under IRC §911 and Form 2555.

For tax year 2026, the maximum exclusion is $132,900 per qualifying person.

However, there is an important distinction:

Taxable income and income available for family support are not necessarily identical concepts.

Thus, someone should not automatically assume that income excluded from federal income taxation is also ignored when determining child-support or alimony capacity. State family-law rules determine how income is counted.

4. Foreign tax payments

If the person pays income tax to another country, the U.S. taxpayer may potentially claim a foreign tax credit, subject to the applicable rules.

The IRS specifically explains that U.S. citizens and resident aliens abroad generally report worldwide income and may qualify for foreign tax credits or other relief.

For support purposes, however, the court may need to distinguish between:

Gross foreign earnings → foreign taxes → U.S. taxes → legitimate expenses → disposable/support income.

The methodology depends on the applicable state's support guidelines.

5. Concealment or understatement of foreign income

Foreign income can become particularly important when one spouse or parent claims that they have little income in the United States while receiving substantial income abroad.

Courts can examine evidence such as:

• Foreign employment contracts
• Foreign tax returns
• Bank statements
• Pay slips
• Business records
• Foreign property income
• Corporate ownership
• Investment accounts
• Currency transfers
• Lifestyle and expenditures
• Financial affidavits and discovery responses

A party generally cannot avoid disclosure merely because the money is held in another country.

6. Foreign bank accounts

Foreign financial accounts can also create U.S. reporting obligations. U.S. taxpayers may have FBAR and/or FATCA reporting requirements depending on the circumstances.

These reporting records can sometimes become relevant evidence in a family-law financial investigation, although the rules governing admissibility and discovery are separate from the tax-reporting rules.

7. Child support example

Suppose a parent lives in the United States but earns:

• U.S. salary: $50,000
• Foreign consulting income: $70,000
• Foreign rental income: $20,000

The parent may argue that only the $50,000 U.S. salary should be considered.

That argument is not necessarily correct. Depending on the state's support guidelines, some or all of the foreign earnings and investment income may enter the support calculation.

The court would then determine which amounts constitute income under that state's statutory definition and what deductions are permitted.

8. Spousal support

Foreign income can similarly be relevant to alimony/spousal-support determinations.

A court may consider:

• earning capacity;
• actual earnings;
• assets and investments;
• foreign employment;
• foreign business interests;
• financial needs of both spouses;
• marital standard of living; and
• ability of the supporting spouse to pay.

Again, state law controls because the United States does not have one nationwide alimony formula.

Key legal distinction

Bottom line: In U.S. family law, earning money abroad does not ordinarily make that money irrelevant to support. The critical question is how the applicable state's support statute defines income and available financial resources. Federal tax treatment, including the foreign earned income exclusion, is a separate question.
