« Back to Glossary Index

A tax-deferred account is an account where tax on income, contributions, or investment growth is delayed until a later event, usually a withdrawal or distribution. Common U.S. examples include traditional IRAs, 401(k)s, 403(b)s, and some pension accounts, while foreign examples may include employer pensions, retirement schemes, or deferred compensation plans.

Why it matters for U.S. expats

Tax-deferred accounts matter because an account that is tax-deferred in one country may not receive the same treatment under U.S. tax rules. A U.S. expat may need to report contributions, growth, distributions, or account values on a U.S. tax return, FBAR, Form 8938, or other foreign reporting forms.

Common questions

1. What is a tax-deferred account?

A tax-deferred account is an account where tax is postponed until a later date, often when the taxpayer withdraws money or receives a pension distribution.

2. What are examples of U.S. tax-deferred accounts?

Common U.S. tax-deferred accounts include traditional IRAs, 401(k)s, 403(b)s, 457 plans, and some employer pension plans.

3. Are foreign retirement accounts tax-deferred for U.S. tax purposes?

Not always. A foreign retirement account may be tax-deferred in the country where it is held, but the United States may tax contributions, growth, or distributions differently.

4. Do tax-deferred accounts need to be reported on FBAR?

Foreign tax-deferred accounts may need to be reported on FBAR if they meet the foreign financial account rules and the taxpayer’s total foreign account values exceed the filing threshold.

5. Do tax-deferred accounts need to be reported on Form 8938?

Foreign pension and deferred compensation interests may need to be reported on Form 8938 if the taxpayer meets the specified foreign financial asset threshold.

6. Are U.S. IRAs and 401(k)s reported on Form 8938?

U.S.-based IRAs and 401(k)s maintained by U.S. financial institutions are usually not reported on Form 8938, even if they hold foreign investments.

7. Are withdrawals from tax-deferred accounts taxable?

Usually, yes. Withdrawals from U.S. tax-deferred accounts are often taxable when distributed, and foreign pension or retirement distributions may also be taxable on a U.S. return.

8. Can a tax treaty help with foreign tax-deferred accounts?

Sometimes. A tax treaty may affect how pensions or retirement distributions are taxed, but treaty treatment depends on the country, account type, taxpayer status, and whether the saving clause limits the benefit.

When to get help

Professional guidance is important when:

  • You have a foreign pension, retirement account, or deferred compensation plan.
  • You are unsure whether an account is tax-deferred under U.S. tax rules.
  • You contributed to a foreign retirement plan while living abroad.
  • You received a pension, annuity, lump sum, rollover, or retirement distribution.
  • You need to decide whether FBAR, Form 8938, Form 3520, or another foreign reporting form applies.
  • You have a U.S. IRA or 401(k) and live in a country that may tax the account differently.
  • You want to use a tax treaty or Foreign Tax Credit to reduce double taxation.
