Do S-corps Need to File the Beneficial Information Ownership Report (BOIR)?

Are you an S-Corps owner wondering if you're required to file the Beneficial Ownership Information Report (BOIR)? With new regulations around beneficial ownership, understanding your reporting obligations is essential to avoid penalties and stay compliant.


The Beneficial Ownership Information Report (BOIR) is a streamlined report designed to take only a few hours to complete, depending on the complexity of the S-Corp's ownership. Its goal is to increase transparency by identifying individuals who hold significant control or benefit from an S-Corp. However, it comes with important restrictions: only specific information is required about each beneficial owner, and only those meeting set ownership or control thresholds need to be listed. Ensuring accurate reporting helps keep your S-Corp compliant and minimizes potential penalties.

What is the Beneficial Ownership Information Report (BOIR)?

The Beneficial Ownership Information Report, or BOIR, is a federal filing requirement intended to identify individuals who directly or indirectly control or profit from an S-Corp or other covered entities. This report is part of broader anti-money laundering and transparency initiatives to prevent illegal activities and maintain compliance across organizations.


  • Purpose: BOIR helps federal agencies identify and monitor beneficial owners to improve transparency and prevent illicit activities, such as money laundering and tax evasion.

  • Definition of Beneficial Ownership: A beneficial owner is any individual who, directly or indirectly, has a significant stake in or exercises substantial control over the S-Corp. The threshold and criteria for what constitutes "substantial control" may vary but typically include ownership percentages and decision-making authority.

  • Required Information: The report generally requires detailed personal information about each beneficial owner, such as full name, date of birth, address, and unique identifying information (like a government-issued ID number).

  • Frequency of Filing: BOIR is typically a one-time filing with updates required only when there are changes in beneficial ownership or control, helping to keep reporting straightforward for businesses while maintaining up-to-date records.


Do S-Corps have to file the Beneficial Ownership Information Report (BOIR)?

S-Corps generally fall under the reporting requirements for the BOIR, as they are considered covered entities by federal standards. However, specific details surrounding which S-Corps are required to file may vary based on certain characteristics.


  • Standard S-Corps: Most S-Corps are required to file the BOIR unless they meet specific exemption criteria set forth in the regulations.

  • Exemptions: Certain S-Corps, such as inactive companies, companies with minimal assets, or entities already subject to specific federal regulations, may qualify for exemption. It's essential to review these exemptions with a professional to determine if your S-Corp qualifies.

  • Foreign-Owned S-Corps: S-Corps with foreign ownership are typically required to file, as they are considered a higher priority for beneficial ownership tracking. If your S-Corp has foreign stakeholders, BOIR compliance becomes particularly relevant.


For S-Corp owners, understanding these distinctions is crucial to determining their filing obligations. A tax professional can offer guidance based on the unique setup and activity of each S-Corp to ensure compliance with the BOIR requirements.


What are the steps to preparing the Beneficial Ownership Information Report (BOIR)?

Preparing the BOIR involves several steps to ensure all required information about beneficial owners is accurately reported.


Here are the following steps:

  1. Identify Beneficial Owners:

    1. Start by identifying all individuals who directly or indirectly own or control the S-Corp. This includes those with significant voting rights, managerial control, or a substantial ownership stake.

    2. Use regulatory guidelines to determine the percentage of ownership or control required to qualify as a beneficial owner.

  2. Gather Required Information:

    1. For each beneficial owner, collect detailed information, including full name, date of birth, residential address, and a unique identification number (such as a Social Security Number or government-issued ID).

    2. Verify that each piece of information is current and matches official records to avoid issues with filing.

  3. Complete the BOIR Form:

    1. Complete the official BOIR form, accurately entering each owner’s information. Check for any recent updates to the form or additional fields that may have been introduced.

    2. Take note of instructions specific to S-Corps, as well as any applicable exemptions for certain types of businesses.

  4. Submit the BOIR Form:

    1. Submit the completed form to the appropriate federal agency, usually through an online portal or as directed by regulatory authorities. Retain a copy of the submission for your records.

    2. Be mindful of deadlines, as late filings can incur penalties. Some filings may need to be submitted within a set period after S-Corp formation or changes in ownership.

  5. Monitor for Changes:

    1. After filing, monitor for any changes in ownership or control within your S-Corp. If changes occur, an updated BOIR must be filed within a specified period to reflect the new ownership structure.


Following these steps can help ensure S-Corp owners meet their BOIR filing requirements accurately and in a timely manner. Consulting a tax professional throughout the process can streamline preparation and minimize the risk of errors.


When is the Beneficial Ownership Information Report (BOIR) Due?

The timing of the BOIR filing depends on the specific circumstances of the S-Corp, including its formation date and any subsequent changes in ownership.


To avoid penalties, S-Corp owners should be aware of the following deadlines:

  • Initial Filing Deadline:

    • New S-Corps are typically required to file the BOIR shortly after formation. Check specific federal guidelines to determine the exact period, as this can vary but is often within 30 days of entity formation.

  • Annual Filing Requirements:

    • Currently, the BOIR is a one-time filing. However, if ongoing annual filing is mandated by future regulations, S-Corps will need to review and re-file annually.

  • Updates Due to Ownership Changes:

    • Any changes in beneficial ownership, such as a transfer of significant control or ownership percentage, require an updated BOIR filing. This update is usually due within 30 days of the ownership change, ensuring federal agencies have the most current information on file.

  • Penalties for Late Filing:

    • Failing to file the BOIR on time, whether as an initial report or an update, can result in penalties. These penalties can include fines, additional administrative requirements, and potential audits.


By staying on top of these deadlines, S-Corp owners can avoid penalties and ensure they remain in compliance with BOIR requirements. A tax advisor or legal professional can help S-Corps track deadlines and file updates as needed.


Most common myths the Beneficial Ownership Information Report (BOIR)

Myth: Only large corporations need to file the BOIR.

Reality: The BOIR applies to many entities, including S-Corps, regardless of size. Small S-Corps often believe they’re exempt, but the filing requirement is based on ownership structure, not company size.


Myth: The BOIR is an annual requirement.

Reality: Currently, the BOIR is a one-time filing unless there are changes in beneficial ownership or control. This minimizes the burden on businesses and simplifies compliance unless significant changes occur.


Myth: Filing the BOIR discloses confidential business information.

Reality: The BOIR only requires basic information about beneficial owners (name, date of birth, address, and unique identifier). It does not request proprietary business details, keeping sensitive business information confidential.


Myth: Only U.S. citizens need to be listed as beneficial owners.

Reality: Beneficial ownership reporting includes foreign nationals if they meet ownership or control thresholds. This allows U.S. regulators to monitor ownership structures regardless of nationality.


Myth: Late filing won’t have serious consequences.

Reality: Late filing can result in penalties, including fines and potential audits. Staying compliant with BOIR deadlines is essential to avoid these consequences, even for small or single-member S-Corps.
