Overview of Form 8937
Form 8937 reports organizational actions that alter the basis of securities held by U.S. taxpayers. It applies to both domestic and foreign issuers when a change—such as a split, dividend, or conversion—affects shareholder cost basis. Accurate filing safeguards tax compliance
Purpose
Form 8937 is the IRS’s formal mechanism for reporting corporate or issuer actions that alter the cost basis of securities held by U.S. taxpayers. Its primary purpose is to provide the Treasury with the data needed to adjust the basis of shares, bonds, or other instruments when an event—such as a stock split, dividend, return of capital, or conversion—changes the amount that a holder must use to calculate gain or loss on disposition. By collecting this information, the IRS can ensure that tax returns reflect the correct basis, preventing under‑or over‑payment of capital gains tax. The form also serves as a safeguard for issuers, helping them avoid penalties that arise from failing to report basis‑affecting events. In practice, the purpose of Form 8937 is to bridge the gap between corporate actions and individual tax reporting, ensuring that the basis adjustments required by the Internal Revenue Code are accurately captured and applied in the taxpayer’s return. This alignment is critical for maintaining the integrity of the U.S. tax system and for protecting both issuers and shareholders from inadvertent tax errors. Specifically, the form captures details such as the type of action, the number of shares affected, and the adjusted basis per share. This data allows the IRS to compute the correct gain or loss when the security is later sold or exchanged. Failure to report can lead to inaccurate tax filings, potential audits, and penalties!!
Scope
Form 8937 applies to any issuer—domestic or foreign—whose securities are owned by U.S. taxpayers, whether directly. The scope covers all organizational actions that alter the basis of a security after the 2010 cutoff, including stock splits, stock dividends, return‑of‑capital distributions, and conversion or exchange of securities. It also includes certain corporate restructurings, such as mergers, consolidations, and spin‑offs, when the transaction changes the holder’s basis. The form is required for each affected security class, regardless of the number of shareholders, and applies even if the issuer is a foreign corporation, provided the security is held by a U.S. taxpayer. The scope does not extend to actions that do not affect basis, such as ordinary dividends or interest payments, nor to securities held by non‑U.S. taxpayers. The IRS requires the issuer to file Form 8937 for each reporting period in which a basis‑affecting event occurs, ensuring that the correct adjusted basis is reflected in the taxpayer’s return. Issuers must also report any changes in the number of shares outstanding that result from a split or reverse split, as these events directly influence the per‑share basis calculation. Additionally, if a security is converted into a different class or into a different instrument, the conversion rate adjustment must be reported to reflect the new basis. The form captures the effective date of the event, the number of shares before and after the action, and the adjusted basis per share. This information allows the IRS to recalculate the basis for each shareholder accurately. Failure to report within the required timeframe can result in penalties and audit exposure. Therefore, understanding the full scope of events that trigger Form 8937 is essential for compliance. Issuers should keep a log of each event, noting dates, share counts, and basis changes, facilitate reporting daily. and file now
Key Features
Form 8937 is the sole reporting tool for issuers to disclose any organizational action that modifies the cost basis of a security held by a U.S. taxpayer. Its primary functions include:
- Capturing the pre‑and post‑event share counts and the adjusted basis per share.
- Documenting the effective date of the event, which is critical for determining the correct basis for subsequent tax years.
- Providing a standardized method for issuers to report stock splits, reverse splits, stock dividends, return‑of‑capital distributions, and conversion or exchange transactions.
- Requiring issuers to submit the form electronically via the IRS e‑Filing system for domestic issuers and by paper for foreign issuers when electronic filing is not available.
- Including a mandatory schedule that lists each affected security class, the number of shares before and after the event, and the basis adjustment amount.
- Enabling the IRS to recalculate shareholder basis and prevent double‑counting or under‑reporting of gains and losses.
Issuers must file the form within the reporting period that follows the event, typically within the same calendar year, and attach any supplemental schedules. Failure to comply can result in penalties, audit triggers, and potential adjustments to shareholder basis. Issuers should keep records to support adjustments aid IRS inquiries!
Applicability
Form 8937 applies to any issuer—domestic or foreign—whose securities are owned by U.S. taxpayers, whether directly or via depositary receipts. The form is triggered by organizational actions that alter the basis of a security, such as a stock split, reverse split, stock dividend, return‑of‑capital distribution, or conversion of a debt instrument into equity. Issuers must file the form for each security class affected by the event, regardless of the number of shares or the size of the adjustment. The reporting obligation extends to securities issued after 2010, and the form must be filed for events that occur in the calendar year following the event, or within the same year if the event occurs early. Foreign issuers must file electronically if they have an electronic filing capability; otherwise, paper filing is required. The form is not required for actions that do not change basis, such as a simple transfer of shares or a non‑taxable sale. However, if the action results in a basis adjustment, the issuer must report it. The IRS requires that the issuer provide the pre‑and post‑event share counts, the basis per share before and after the event, and the effective date; Failure to file can lead to penalties and audit triggers. Proper filing ensures accurate shareholder basis, preventing double‑counting of gains or losses on subsequent sales. Issuers should consult the latest IRS instructions to confirm filing deadlines and required schedules, as changes in regulation may affect the reporting process. The form is filed annually, and each filing must be accompanied by the appropriate supporting schedules detailing the specific adjustments for each affected security class.
Filing Requirements and Procedures
Issuers must file Form 8937 annually, reporting basis changes from splits, dividends, or conversions. Provide pre‑ and post‑event share counts, basis per share, and effective dates. Submit electronically or by paper, following IRS instructions, to avoid penalties. 2026.!
Domestic Issuers
Domestic issuers of securities that are held by U.S. taxpayers must file Form 8937 when an organizational action—such as a stock split, dividend, or conversion—affects the basis of those securities. The filing is required for each calendar year in which a qualifying event occurs. To comply, issuers must gather the following data for every class of security: the number of shares before the event, the number after the event, the adjusted basis per share before the event, the adjusted basis per share after the event, and the effective date of the event. The form must be completed in the issuer’s name, with the taxpayer identification number (TIN) and the SEC registration number of the security. Electronic filing is encouraged; paper copies are accepted but must be mailed to the IRS address specified in the instructions. Failure to file or late filing can result in penalties of up to $5,000 per event, and inaccurate reporting may trigger audit scrutiny. For guidance on calculating adjusted basis and reporting multiple events in a single year, issuers should consult the IRS instructions for Form 8937 and, if necessary, seek professional tax advice. Domestic issuers should also verify that any changes to the security’s registration or ownership structure are reflected in the filing, as omissions can lead to double‑counting of basis adjustments and trigger compliance reviews daily!.
Foreign Issuers
Foreign issuers whose securities are owned by U.S. taxpayers must file Form 8937 when an organizational action—such as a stock split, dividend, or conversion—impacts the basis of those securities. The filing requirement applies to each calendar year in which a qualifying event occurs. Foreign issuers should identify the security’s registration number, the issuer’s TIN (if available), and the SEC registration number if the security is listed in the U.S. The form requires the issuer to report, for each class of security, the number of shares before and after the event, the adjusted basis per share before and after the event, and the effective date of the event. If the issuer is not a U.S. corporation, it may need to provide a U.S. taxpayer identification number or a foreign equivalent; failure to provide a TIN may result in a 10% withholding on dividends. Electronic filing is encouraged; paper copies must be mailed to the address listed in the instructions. Late filing penalties can reach $5,000 per event, and inaccurate reporting may trigger audit scrutiny. Foreign issuers should consult the IRS instructions for Form 8937 and, if necessary, seek professional tax advice to ensure compliance with U.S. tax law and avoid double‑counting of basis adjustments. The form must be filed within 30 days of the event’s effective date, and any changes to the security’s ownership structure must be reflected in the filing to maintain accurate basis records for U.S. shareholders to
Triggering Events
Form 8937 must be filed whenever an organizational action changes the basis of a security held by a U.S. taxpayer. The IRS defines several key events that trigger the reporting requirement. A nontaxable cash distribution to shareholders, even if the dividend is not taxable, alters the basis of the remaining shares and must be reported. Likewise, a nontaxable stock distribution—such as a stock split, reverse split, or bonus issue—changes the number of shares and the per‑share basis. Convertible debt instruments that are converted into equity also trigger a basis adjustment; the conversion rate and the new share count must be reported. A change in the security’s registration status, including a new registration statement or a delisting, can affect basis if the security is held by U.S. taxpayers. In addition, a corporate reorganization that results in a change of control or a merger that creates a new class of securities requires reporting. The effective date of the event is the date on which the change becomes effective for the shareholders; the issuer must file within 30 days of that date. Failure to report any of these events can lead to inaccurate basis calculations for shareholders, potentially resulting in higher taxable gains or losses when the securities are sold. The form also requires the issuer to provide the number of shares before and after the event, the basis per share before and after, and the total adjusted basis for each class of security involved. Accurate reporting ensures that U.S. shareholders can correctly compute their capital gains or losses and comply with IRS regulations.
Information Collection
Issuers must gather detailed data before completing Form 8937. The IRS requires the issuer’s legal name, EIN, and the security’s CUSIP or other identifying number. For each event, the issuer must provide the effective date, the type of action (e.g., split, dividend, conversion), and the number of shares or units before and after the event. Basis amounts per share before and after the event must be calculated and reported, as well as the total adjusted basis for each class of security. If the issuer is foreign, the issuer must also supply a country of incorporation, the U.S. taxpayer’s name and taxpayer identification number, and the U.S. withholding tax election. The form demands a narrative description of the event, the reason for the basis change, and any related corporate filings that support the change. The issuer must also collect any supporting documents, such as board minutes, stock split certificates, or conversion agreements, and attach them as required. The IRS requires that the issuer’s signature and the date of signing be included, and that the form be filed electronically or on paper, depending on the issuer’s filing method. Accurate collection of this information prevents errors that could trigger penalties or audit inquiries. The IRS provides a detailed checklist in the instructions to ensure all required data are captured before submission. Ensure data accuracy.now
Form Completion
To complete Form 8937, choose Part I for domestic issuers or Part II for foreign issuers. Each part contains a series of boxes that correspond to specific organizational events. For each event, enter the issuer’s name, the security’s identifier, the event date, and the type of action (e.g., split, dividend, conversion). The form requires the number of shares before and after the event, the adjusted basis per share, and the total adjusted basis. For foreign issuers, the form adds a box for the country of incorporation and a U.S. withholding election. Each event must be entered on a separate line, and the total number of events is reported in the final box. The form also includes a section for the issuer’s signature, date, and the name and title of the signer. When filing electronically, convert the form to PDF and submit through the IRS e‑File system, ensuring the PDF is not password protected. If filing by paper, print the form on the official IRS paper and mail it to the address listed in the instructions. The IRS recommends reviewing the completed form for accuracy before submission, as errors can trigger penalties or the need for a corrected filing. The form’s instructions illustrate a split!. After completing the form, attach any required schedules or supporting documents as outlined in the instructions. The completed form is then ready for submission.
Supporting Schedules
Supporting schedules are required when the issuer’s organizational action involves more than a single class of securities or when the action triggers a complex basis adjustment. Schedule A, “Details of Organizational Actions,” lists each event, the security’s CUSIP, the event date, the type of action, the number of shares before and after, and the adjusted basis per share. For foreign issuers, Schedule B, “Foreign Issuer Information,” must be completed, providing the country of incorporation, the issuer’s foreign tax identification number, and the U.S. withholding election. If the event involves a stock split or dividend that results in a change in the number of shares, Schedule C, “Split and Dividend Details,” must be attached, showing the split ratio, the dividend amount per share, and the adjusted basis calculation. In cases where the action affects a convertible security, Schedule D, “Convertible Security Adjustments,” must be filed, detailing the conversion rate, the number of shares converted, and the new basis. All schedules must be signed by the issuer’s authorized officer and dated. The IRS requires that each schedule be attached to the main Form 8937 and that the schedules be in the same order as the events listed on the form. Failure to attach the required schedules can result in a penalty for incomplete filing. The instructions advise reviewing the schedules for accuracy and completeness before submission, as errors may trigger additional correspondence from the IRS. Schedules mailed.
Submission Methods
Form 8937 may be filed electronically via the IRS e‑File portal or by paper. Electronic filing is preferred because it provides instant confirmation and faster processing. To e‑file, issuers need a valid IRS e‑File PIN, the issuer’s tax ID, and a signed electronic signature. The portal accepts PDF, Word, or Excel and validates data before submission. Paper filing is available for issuers without e‑File access. Completed forms must be printed on official IRS paper, signed, and mailed to the address listed in the instructions. Domestic issuers send to 1500 Pennsylvania Avenue, NW, Washington, DC 20220; foreign issuers use the same address with the “Foreign Issuer” line completed. All paper submissions must include the required supporting schedules, a signed cover sheet, and the issuer’s tax ID. The IRS recommends sending paper via certified mail or a courier that provides delivery confirmation. Whether filing electronically or by paper, issuers should retain a copy of the completed form and all schedules for at least seven years, as the IRS may request them in a compliance audit. Electronic submissions are processed within 10 business days; paper submissions typically take 30 business days.

Deadlines, Locations, and Penalties
Form 8937 must be filed by the tax year’s due date, typically April 15 for most issuers, or the extended deadline if applicable. Mail to the IRS address in the instructions. Late filings incur penalties of $100 per day, capped at 25% of the tax due File promptly avoid now.
Reporting Periods
The reporting period for Form 8937 is defined by the calendar year in which the organizational action takes place. For issuers, this means that any event—such as a stock split, dividend, or conversion—that occurs on or after January 1, 2011 must be reported in the following tax year. If the action occurs before 2011, it is reported in the same year. Multiple actions within a single year are consolidated onto one form, with each event listed on a separate line. When an action is a continuation of a prior event, the reporting period remains the year of the original event. Issuers must also consider the effective date of the action; if the effect begins in a later year, the reporting period shifts accordingly. The IRS instructions emphasize that the reporting period is tied to the date of the action, not the filing date. Accurate alignment of the reporting period ensures proper basis adjustments and avoids penalties. Therefore, issuers should maintain detailed records of all dates and reference the IRS guidance for the applicable tax year when completing the form. Foreign issuers must use the U.S. taxpayer’s calendar year. If an action is part of related events, each must be reported in its occurrence year. Documentation of the action’s effective date and type is essential. Incorrect reporting periods cause basis errors, tax adjustments, or penalties. Timely filing ensures compliance now and accurate record keeping for compliance now.
Filing Deadlines and Locations
Issuers must submit Form 8937 by the due date of the issuer’s annual return, typically April 15 for corporations or the due date of the issuer’s tax return for other entities. If the issuer files electronically, the form can be attached to the electronic return using the IRS e‑file system; paper copies are mailed to the IRS address specified in the instructions. For domestic issuers, the mailing address is the same as for the issuer’s return, while foreign issuers use the foreign address listed in the instructions. The IRS requires the form to be filed within the same tax year as the reporting period, with no extensions granted. Failure to file by the deadline triggers a penalty of $200 per day, capped at the total amount of the penalty for the year. The instructions advise that the form be filed on the same day the issuer’s return is filed to avoid separate processing. For issuers who are required to file Form 8937 for multiple securities, each security’s action must be reported on a separate line, and the form must be mailed or e‑filed in full. Filings must include schedules attached to the the form!
Late Filing Penalties
When an issuer fails to submit Form 8937 by the due date, the IRS imposes a daily penalty of $200 for each day the form remains outstanding, up to a maximum of $10,000 per issuer per year. The penalty is assessed on the date the form would have been filed, not on the actual filing date, and is calculated by multiplying the daily amount by the number of days late. The IRS allows a one‑time waiver of the penalty if the issuer can demonstrate reasonable cause, such as a natural disaster or a system failure, and the issuer must request the waiver in writing within 30 days of the filing deadline. If the waiver is denied, the penalty remains in effect until the form is filed. The penalty is separate from any other tax or filing penalties that may apply to the issuer’s return. The IRS may also impose interest on the penalty amount at the federal short‑term rate plus 3 percentage points. The interest accrues from the due date of the form until the penalty is paid in full. For foreign issuers, the penalty applies to the same daily rate, but the form must be mailed to the foreign address listed in the instructions. The IRS recommends filing electronically to avoid delays and reduce the risk of late penalties. The penalty schedule is published in the IRS Form 8937 instructions and can be found on the IRS website under the “Penalties” section. Proper documentation, such as proof of attempted filing, can support a waiver request. Failure to address the penalty can result in additional enforcement actions, including liens or levies on the issuer’s assets. Therefore, issuers should monitor the filing deadline closely, maintain accurate records, and file promptly to avoid the $200 daily penalty and associated interest charges. Additionally, the IRS may reassess the penalty if the issuer fails to correct the form within 30 days of receiving notice of the penalty, potentially doubling the daily amount for the remaining days. Issuers are encouraged to retain copies of all correspondence with the IRS and to keep evidence of timely filing, such as confirmation receipts from the e‑filing system, to support any future disputes. The IRS also provides a penalty relief program for small issuers, allowing them to pay the penalty in installments if they meet certain criteria. Compliance with the penalty schedule is essential to maintain good standing with the IRS and to prevent escalation to more severe enforcement actions.
