What IRS Form 3520-A (2021) Is For
IRS Form 3520-A serves as the annual information return that a foreign trust must file with the Internal Revenue Service. The return provides essential details about the trust’s income, assets, and transactions with United States persons. The Internal Revenue Service reviews the filing to confirm compliance with international tax law and reporting requirements under the Internal Revenue Code.
If the trustee of the foreign trust fails to file, the U.S. owner must separately file a substitute Form 3520-A along with their income tax return. The form identifies the foreign grantor, U.S. beneficiaries, and foreign persons involved in the trust’s operations. Submitting a complete return supports transparency, ensures compliance, and helps avoid penalties related to incomplete annual information reporting.
More information on international filing obligations is available in the International & Foreign Reporting Forms resource.
When You’d Use Form 3520-A for 2021
Taxpayers file Form 3520-A when the trust appointed for reporting fails to meet its annual filing requirements. A U.S. owner, trustee, or representative must complete the annual return to report transactions with foreign trusts and confirm the trust’s compliance with grantor trust rules. Late or amended filing may also occur when correcting inaccurate information returns of foreign trusts.
- A U.S. owner must file Form 3520-A if the foreign trust did not submit the return for the calendar year.
- Filing is required when the Internal Revenue Service issues a notice for failure to file or requests missing tax forms.
- Corrections are necessary when the trust includes certain foreign gifts, foreign non-grantor trust assets, or misreported gross value.
Timely filing supports compliance with annual information reporting requirements and reduces potential penalties.
Key Rules or Details for 2021
Foreign trusts and any U.S. owners must follow the 2021 reporting requirements. These rules cover income, capital gains, gift taxes, and large gifts. Accurate filings protect U.S. beneficiaries and other U.S. persons from penalties.
Penalty Structure and Filing Requirements
File by the due date for the trust’s tax year. A trust with a U.S. owner that fails to file faces an initial penalty. Criminal penalties may apply when a false or incomplete Part I or Part II is submitted.
Filing Period and Extensions
The time to file depends on the calendar year or fiscal year selected. Request an automatic six-month extension when records remain outstanding or when third parties delay responses. The IRS mails confirmations and correspondence that specify next steps, deadlines, and any balances due. For help with your tax questions and payment options, consider calling the IRS or consulting a comprehensive guide.

Common Mistakes and How to Avoid Them
Taxpayers frequently experience processing delays on Form 3520-A due to missing schedules, unsigned pages, or inconsistent identifiers. Early detection of these issues strengthens compliance and limits additional requests from the Internal Revenue Service. Accurate and complete reporting also supports proper verification of foreign trust information.
- Omitted Trustee Signature: This mistake occurs when the trustee submits the return without a signed certification page. The filer must confirm that the trustee signs Part II before assembling the final return.
- Incorrect Tax Year Reporting: This error occurs when the trust reports a tax year that does not match its established accounting period. The filer must verify the trust’s designated year-end before completing schedules.
- Missing Beneficiary Statements: This issue occurs when the filing excludes beneficiary statements required under annual reporting rules. The filer must prepare and attach each beneficiary’s complete statement.
- Inconsistent Foreign Asset Reporting: This problem occurs when asset descriptions or values differ across schedules. The filer must confirm that disclosed assets match supporting documents.
What Happens After You File
After submission, the Internal Revenue Service reviews the return for accuracy and completeness. Each U.S. owner and trustee should expect correspondence if the Internal Revenue Service identifies missing information or unverified trust documents to ensure a prompt review process. Maintaining updated records helps ensure an efficient review process.
Acknowledgment Notice
The Internal Revenue Service sends an acknowledgment confirming that the return was received and entered for processing. The notice confirms the filing date for recordkeeping.
Information Requests
If any trust documents or schedules are incomplete, the Internal Revenue Service may request clarification from the U.S. owner or trustee. Prompt responses reduce processing delays.
Potential Follow-Up
Late or incorrect filings involving certain foreign gifts may trigger additional penalties. Keeping complete documentation for U.S. owners, U.S. beneficiaries, and U.S. persons supports compliance and efficient resolution.
