FBAR and Form 8938: reporting Costa Rican accounts

The $10,000 account threshold, separate asset-reporting rules and the records to start keeping now.

A local account can create a U.S. reporting task

A Costa Rican account used for rent and groceries can fall within foreign-account reporting rules even when it earns very little interest. The IRS FBAR overview applies the test to U.S. persons with a financial interest in, or signature authority over, reportable foreign financial accounts. The threshold is more than US$10,000 in aggregate at any time during the calendar year.

It is not a separate US$10,000 allowance at each bank. In a simple example, two reportable accounts holding US$6,000 each at the same time produce a combined US$12,000 balance. The example triggers the threshold even though neither account individually reaches US$10,000. A temporary balance before a large purchase can matter too.

This reporting question is separate from how much U.S. income tax you owe.

Distinguish the two reports

The IRS comparison of FBAR and Form 8938 makes clear that one filing does not replace the other. An FBAR goes to FinCEN through its electronic filing system. Form 8938, when required, accompanies your federal income-tax return and can cover specified foreign financial assets beyond bank accounts.

ReportThreshold to investigateFiling route
FBARForeign accounts together exceed $10,000 at any timeFinCEN, separately from the tax return
Form 8938: qualifying individual abroad, single or filing separatelyOver $200,000 at year-end or $300,000 at any timeWith the federal return
Form 8938: qualifying married couple abroad filing jointlyOver $400,000 at year-end or $600,000 at any timeWith the joint federal return

These are reporting thresholds, not tax-free allowances. The Form 8938 figures above apply only when the foreign-residence conditions are satisfied.

Do not assume the higher overseas thresholds apply immediately

The Form 8938 instructions require a foreign tax home plus a qualifying presence-abroad test. For U.S. citizens, the bona fide residence route must include an entire tax year; another route requires at least 330 full days in foreign countries during the relevant 12-month period ending in the reported tax year. A Costa Rican residency card or a foreign mailing address alone does not establish these conditions.

Ask your preparer which thresholds apply in your departure year. If you do not meet the overseas conditions, lower U.S.-resident thresholds may apply. The instructions also say Form 8938 is not required solely because of the asset values when you have no income-tax-return filing requirement. That does not resolve a separate FBAR obligation.

Inventory accounts and ownership before year-end

List each institution, country, account owner, account type and any authority you have over someone else’s account. The IRS comparison distinguishes signature authority from ownership and shows that directly held foreign real estate is generally outside these two reports. A foreign entity holding property can create different reporting questions.

Flag joint accounts, business accounts and foreign investment products for review. Do not assume a spouse’s filing covers yours or that a foreign company makes the underlying interest irrelevant. Give the preparer the ownership documents along with the statements.

Keep a repeatable annual record

FinCEN’s recordkeeping guidance calls for account identifiers, the institution’s name and address, account type and maximum value. Records generally must be retained for five years from April 15 following the reported calendar year.

Download statements as you go, including for accounts you close. Record balances in the account’s currency and ask your preparer to apply the required valuation and conversion method. A screenshot of the balance on December 31 does not show an earlier peak.

The FBAR deadline is generally April 15 after the reported year, with an automatic extension to October 15. Confirm the calendar and any applicable relief for your filing year. If earlier reports were missed, gather the facts and obtain advice about correction procedures rather than guessing at a late submission.
