Need Help Filing FATCA (Form 8938)? Avoid Costly Mistakes Before You Submit

If your foreign accounts, investments, pensions, or overseas assets cross IRS reporting thresholds, Form 8938 compliance is not optional. 

Form 8938 is a required IRS disclosure for U.S. taxpayers with specified foreign financial assets above set dollar thresholds. Skip it or file it wrong, and the IRS charges $10,000 per year, starting the day after your filing deadline.

This guide covers who must file, what counts as reportable, the most costly common Form 8938 filing mistakes, and how to file correctly, based directly on official IRS Form 8938 instructions and IRC Section 6038D.

What is FATCA and Why Does Form 8938 Reporting Matter?

FATCA (Foreign Account Tax Compliance Act) requires U.S. taxpayers to report specified foreign financial assets by attaching Form 8938 to their annual income tax return. 

The legal basis is IRC Section 6038D. Foreign banks in over 100 countries share U.S. account holder data with the IRS under FATCA, so the agency often already has your foreign account details before you even file.

IRS FATCA reporting assistance is worth getting early because FATCA enforcement is data-driven. The IRS cross-references reports from foreign financial institutions, FinCEN filings, and tax treaty partners against your return. Gaps do not go unnoticed.

The IRS Crackdown on Foreign Assets in 2026

The IRS continues expanding its use of international tax reporting frameworks to identify non-filers through automated data matching. A missing Form 8938 does more than create a penalty. It extends the statute of limitations on your entire tax return by 3 years, or 6 years if you omitted more than $5,000 in foreign income.

FATCA vs. FBAR: Do You Need to File Both?

Yes. The differences between FBAR and FATCA show these are entirely separate obligations with different rules, different filing locations, and different consequences:

Filing Form 8938 does not remove your FBAR obligation. Both filings can apply to the same accounts simultaneously.

Who Must File Form 8938? Understanding the Thresholds

You must file Form 8938 if you are a “specified person” with foreign financial assets above the applicable threshold. Specified persons include U.S. citizens, resident aliens, certain nonresident aliens, and specified domestic entities. 

Form 8938 filing requirements vary based on filing status and where you live, which is one of the most misunderstood aspects of the differences between FBAR and FATCA compliance.

Reporting Thresholds for Taxpayers Living in the U.S.

Reporting Thresholds for U.S. Expats (Living Abroad)

To qualify as living abroad, you need a foreign tax home plus either bona fide foreign residence for a full tax year or 330 days of physical presence in foreign countries within any 12 months ending in the tax year.

Form 8938 requirements for dual citizens follow the same thresholds. Dual citizenship is not an exemption. U.S. citizenship alone activates these Form 8938 filing requirements, regardless of any other nationality you hold.\

Specified Foreign Financial Assets: What You Must Disclose

Two categories of Foreign financial assets require disclosure: financial accounts held at foreign institutions, and foreign financial assets held for investment outside any financial account.

Foreign Bank Accounts and Investment Portfolios

Any deposit or custodial account at a foreign bank or financial institution is reportable. This includes foreign savings and checking accounts, brokerage or custodial accounts, and cash value life insurance or annuity contracts at foreign insurers. You report the maximum value during the tax year, not only the December 31 balance.

Stocks, Bonds, and Interests in Foreign Entities

Assets held directly outside a financial account that require disclosure:

• Stock issued by a foreign corporation
• Bonds, notes, or debentures issued by a foreign person
• Capital or profits interest in a foreign partnership
• Interests in a foreign trust or estate
• Derivative instruments with a foreign counterparty

A Form 8938 filing service from a qualified professional helps you identify assets in this category. Foreign stock or partnership interests held directly, rather than through a U.S. brokerage, frequently get missed.

What About Foreign Real Estate and Pensions?

Foreign real estate you own directly is not a specified foreign financial asset. It does not belong on Form 8938. But if you hold real estate through a foreign corporation, trust, or partnership, your interest in that entity is fully reportable.

For U.S. tax rules for foreign pensions, foreign pension plans, and deferred compensation plans are specified foreign financial assets under IRC Section 6038D. You report your interest in the plan itself, not the assets inside it. If you cannot determine fair market value and received no distributions during the year, the IRS instructs you to report zero.

5 Common FATCA Filing Mistakes That Trigger Audits

Getting FATCA filing mistakes help before you submit can prevent the five errors that most reliably result in FATCA-related IRS audits.

1. Confusing Form 8938 with FBAR Requirements

These are separate filings with different thresholds, different asset definitions, and different filing locations. Many filers assume FBAR covers everything foreign. It does not. FATCA filing help from a qualified professional clarifies exactly which forms apply to your assets and situation.

2. Incorrect Currency Conversion Calculations

All foreign asset values on Form 8938 must be converted to U.S. dollars using the U.S. Treasury Bureau of the Fiscal Service exchange rate on the last day of the tax year. If no Treasury rate exists for that currency, use another publicly available rate and disclose it on the form. Using the wrong date or an undisclosed source is a flagged error.

3. Failing to Report Assets in “Tax Haven” Jurisdictions

Accounts in the Cayman Islands, Luxembourg, Singapore, or similar countries are visible to the IRS. FATCA agreements require foreign financial institutions in those countries to report U.S. account holders. Skipping these accounts is a direct foreign income audit trigger.

4. Omitting Income Generated by the Reported Assets

Part III of Form 8938 requires you to report income tied to foreign assets: interest, dividends, royalties, and gains. Reporting the asset in Part V or Part VI while leaving Part III blank signals unreported income. This is one of the most consistent common Form 8938 filing mistakes in audited returns and a reliable foreign income audit trigger that the IRS uses to open inquiries.

5. Missing the Filing Deadline with Your Form 1040

Form 8938 attaches to your annual return and shares its due date, including extensions. You cannot file Form 8938 separately. A late return equals a late Form 8938, and the $10,000 penalty clock starts immediately.

Step-by-Step Guide to Filing Form 8938 Correctly

The step-by-step FATCA filing process starts with preparation, not the form itself.

Step 1: Inventory Your Global Financial Interests

List every foreign account, stock, bond, pension interest, and entity interest that might qualify. When in doubt about an asset, include it. Seek FATCA filing help before excluding anything close to the threshold. 

The most common gap in IRS FATCA reporting assistance cases is a filer who left out an asset that clearly should have been reported. A Form 8938 filing service from a tax professional runs this inventory with you systematically and prevents those gaps from the start.

Step 2: Determine Maximum Value During the Tax Year

For financial accounts, review periodic statements to find the highest balance during the year. For other assets, use the year-end fair market value unless readily available information shows a higher value occurred at any point during the year. Convert all values to U.S. dollars using the December 31 Treasury exchange rate. Total everything to compare against the threshold for your filing status.

Step 3: Cross-Check Data with Foreign Financial Institutions

Request year-end statements from every foreign institution. Part V of Form 8938 requires the institution name, mailing address, and account number for each deposit or custodial account. 

Part VI requires descriptions and identifying details for all other assets. Check Part IV for assets already reported on Forms 3520, 5471, 8621, or 8865. Those are noted on Form 8938 but not duplicated.

The High Cost of Non-Compliance: FATCA Penalties

FATCA non-compliance risks escalate fast. The penalty structure under IRC Section 6038D is designed to compound across years of inaction.

$10,000 Minimum Penalties and Beyond

• Failure to file: $10,000 per tax year, starting at the filing deadline
• Continued failure after IRS notice: $10,000 for each additional 30-day period (or partial period) after the 90-day grace window, up to $50,000 more per year
• Accuracy-related penalty: 40% of any underpayment tied to an undisclosed foreign asset
• Fraud penalty: 75% of the underpayment attributable to fraud
• Statute of limitations: Extended 3 years for a missing filing, or 6 years if omitted foreign income exceeded $5,000

FATCA non-compliance penalties keep the statute of limitations open until the delinquent Form 8938 is actually filed. Avoiding FATCA penalties means filing accurately and on time, every single year. A reasonable cause exception can waive penalties if you prove the failure was not due to willful neglect, but the IRS decides that on a case-by-case basis.
