What IRS Form 3520-A (2015) Is For
IRS Form 3520-A (2015) is the annual return that foreign trusts with U.S. owners must file to report the trust’s financial activities, operations, and ownership details to the Internal Revenue Service. Under the grantor trust rules, any U.S. person treated as the owner of a foreign trust must ensure that this form is filed wholly and accurately each year.
The form provides essential information for income tax purposes, including foreign trust income, trust assets, and distributions made to U.S. owners or beneficiaries. It helps the IRS verify compliance with foreign trust reporting requirements, foreign financial asset disclosure, and tax obligations under the Internal Revenue Code. By submitting this annual return, the filer demonstrates transparency in foreign entity ownership, ensuring that foreign grantor trusts and their foreign persons meet their reporting obligations and avoid penalties imposed for noncompliance.

When You’d Use IRS Form 3520-A (2015)
You should file or amend IRS Form 3520-A (2015) when a foreign trust has not filed on time, or when a previous submission requires correction.
- IRS Notice or Penalty: File the form after receiving IRS Letter 3804 or a notice regarding penalty assessments for a missing or late filing.
- Missed Filing Year: File when you discover that prior years were unreported during a compliance review or audit of foreign trust reporting.
- Error Correction: File to amend incorrect information, such as gross value, trust assets, or foreign trust income previously reported.

Common Mistakes and How to Avoid Them

- Lack of Documentation: Attach all foreign trust documents and amendments when no U.S. agent has been designated to demonstrate compliance and reasonable cause.
- Missing Reasonable Cause Statement: Always include a detailed reasonable cause statement signed under penalties of perjury to explain that the delay was due to ordinary business care and not willful neglect.

What Happens After You File
After you submit IRS Form 3520-A (2015), the Internal Revenue Service typically processes the return within six to eight weeks. If the filing is complete, your account will reflect the update, and the IRS may issue a confirmation notice. If errors remain, you may receive a request for additional information or a penalty notice.
You can seek reasonable cause relief or appeal penalty assessments through the IRS Appeals Office. A properly filed form also begins the three-year statute of limitations, which applies to audits and foreign trust reporting reviews for that tax year. If a foreign trust receives or distributes U.S.-source income, the withholding requirements in our Form 1042 annual withholding tax return guide may also be relevant.
