What Is a Form 1099-CAP: Changes in Corporate Control and Capital Structure?
A Form 1099 in the United States captures the structured information needed to complete the process it supports.
The filing requirement is triggered when the corporation (or its successor) must recognize that shareholders may have a taxable exchange or disposition of their stock as a result of the corporate transaction. Under IRC Section 6043(c), a corporation must file Form 1099-CAP for each shareholder of record who receives cash, stock, or other property as a result of the change in control or capital structure, provided the aggregate amount received exceeds $1,000. The form is filed with the IRS and furnished to shareholders by the applicable deadline, typically January 31 of the year following the transaction.
Form 1099-CAP is particularly important in the context of mergers and acquisitions under IRC Section 368, where the tax consequences to shareholders depend on whether the transaction qualifies as a tax-free reorganization. Even in qualifying reorganizations, shareholders may recognize gain to the extent of "boot" received (cash or other non-qualifying property under IRC Section 356). The form provides shareholders with the information needed to determine their gain or loss on the deemed sale or exchange of their shares, including the aggregate amount of cash and fair market value of any stock or other property received.
When Do You Need a Form 1099-CAP: Changes in Corporate Control and Capital Structure?
Form 1099-CAP is issued when a corporation undergoes a change in control or substantial change in capital structure that results in shareholders receiving cash, stock, or other property in exchange for their shares. The most common triggering event is a corporate merger or acquisition, where the target corporation's shares are cancelled and shareholders receive consideration from the acquiring entity. This includes both cash mergers (where shareholders receive only cash) and stock-for-stock exchanges (where shareholders receive shares in the acquiring corporation).
Other events that trigger Form 1099-CAP include leveraged buyouts (LBOs) where shareholders are cashed out, going-private transactions under SEC Rule 13e-3, corporate liquidations under IRC Section 331, spin-offs and split-offs that involve a significant change in capital structure, and recapitalizations that result in shareholders exchanging one class of stock for another with different rights. Corporate inversions, where a U.S. corporation restructures so that a foreign parent holds the stock, also require filing.
Shareholders who receive Form 1099-CAP must report the transaction on their tax return, typically on Form 8949 and Schedule D. The gain or loss is calculated as the difference between the amount realized (cash plus fair market value of property received) and the shareholder's adjusted basis in the surrendered stock. For reorganizations qualifying under IRC Section 368, the shareholder may defer gain recognition on stock received but must recognize gain on any boot under IRC Section 356(a). If the distribution has the effect of a dividend under IRC Section 356(a)(2), the gain may be recharacterized as ordinary dividend income rather than capital gain.
What to Include in Your Form 1099-CAP: Changes in Corporate Control and Capital Structure
Form 1099-CAP reports several critical data elements for shareholders to compute their tax liability. Box 1 reports the date of the corporate change in control or capital structure, establishing when the deemed sale or exchange occurred for tax purposes. This date determines the shareholder's holding period classification (short-term or long-term capital gain) and the tax year for recognition.
Box 2 reports the aggregate amount of cash received by the shareholder in the transaction. Box 3 reports the aggregate fair market value of stock or other property received (excluding cash). Together, these boxes establish the shareholder's total amount realized. For shareholders who held multiple lots of the target corporation's stock acquired at different times and prices, the total consideration must be allocated across all lots based on their relative fair market values to determine gain or loss on each lot.
Box 4 reports the number of shares of the corporation exchanged by the shareholder in the transaction. This information is used to verify the per-share consideration and reconcile with brokerage records. The form also identifies the corporation whose stock was affected, providing the corporation's name, address, and EIN. Shareholders should compare Form 1099-CAP with their own records of stock purchases, including any reinvested dividends that increased their cost basis. For qualified reorganizations under IRC Section 368, the basis in the new stock received is generally the same as the basis in the old stock surrendered (substituted basis under IRC Section 358), reduced by any boot received and increased by any gain recognized. Proper basis tracking is essential for computing gain or loss on a future disposition of the replacement shares.

}Frequently Asked Questions
Form 1099-CAP, Changes in Corporate Control and Capital Structure, is an IRS information return that reports cash, stock, or other property a shareholder received as a result of an acquisition of control or a substantial change in a corporation's capital structure. The payer or filer sends one copy to the IRS and furnishes another copy to the recipient, who uses the information to report the relevant amounts on their federal tax return. Because the IRS receives its own copy and matches it against the recipient's return, the amounts on the form should be reflected accurately on the recipient's taxes. The form identifies the payer, the recipient, their taxpayer identification numbers, and the reported amounts in numbered boxes. a corporation that undergoes an acquisition of control or substantial change in capital structure issues Form 1099-CAP to affected shareholders. Because the reporting rules and boxes are specific to this form, the filer should confirm which amounts are reportable and the recipient should reconcile the form with their own records before filing their return.
Form 1099-CAP is issued by the entity responsible for the reportable transaction, and a corporation that undergoes an acquisition of control or substantial change in capital structure issues Form 1099-CAP to affected shareholders. The corporation must furnish the recipient copy by January 31 and file with the IRS by February 28 on paper or March 31 electronically. Payers that file 10 or more information returns in total must file electronically under current IRS rules. Penalties apply for filing late, failing to file, or providing incorrect information, and they increase the longer the form is overdue. Because the deadlines are firm and the electronic filing threshold is low, filers should gather the recipient's correct taxpayer identification number, often using Form W-9, well before the due date. Recipients who do not receive an expected form by the deadline should contact the payer, but they remain responsible for reporting the income or transaction on their return regardless of whether the form arrives on time.
When you receive Form 1099-CAP, you should review it for accuracy and use it to report the relevant amounts on your federal tax return, because the IRS receives a matching copy. Amounts on Form 1099-CAP help you determine any taxable gain from the corporate transaction, which you generally report on Schedule D and Form 8949 based on what you received compared with your basis in the shares. Verify that your name, taxpayer identification number, and the reported amounts are correct, and contact the issuer for a corrected form if you find an error, since a mismatch can trigger an IRS notice. Keep the form with your tax records even after you file. Even if the amount seems small or you believe it is not taxable, you should not ignore the form, because the IRS will expect to see it reflected on your return. Because unreported 1099 income can lead to additional tax, interest, and penalties, you should reconcile the form with your records and address any discrepancy with the issuer before filing.
Form 1099-CAP is issued to shareholders when a corporation experiences an acquisition of control or a substantial change in its capital structure and the shareholder receives cash, stock, or other property in exchange for their shares. The form reports the aggregate amount the shareholder received, which the shareholder uses to figure any gain on the deemed sale or exchange of stock. The corporation files the form only when the transaction meets the reporting thresholds set by IRS regulations and the shareholder is not an exempt recipient. Because the transaction is treated as a disposition of the shares, you generally compare what you received against your basis in the stock to compute gain or loss on Schedule D and Form 8949. If the transaction was a tax-free reorganization, different rules may defer gain. Because corporate restructurings can be complex, shareholders who receive Form 1099-CAP should review the transaction details and their stock basis before reporting the result.
Official Form 1099-CAP is available from the IRS, and the copy filed with the IRS generally requires the official scannable format, so a downloaded PDF cannot simply be printed and mailed as the IRS copy. Filers can order official paper forms from the IRS, use accounting or specialized software, or file electronically through the IRS Information Returns Intake System (IRIS) or the FIRE system. Because filers submitting 10 or more total information returns must file electronically, most use software or an electronic filing service. The recipient copy may be furnished on paper or, with the recipient's consent, electronically. The forms-legal.com template helps users organize the information that goes on the form, but the official return must be submitted to the IRS through an approved channel. Because the IRS requires its scannable format for paper filing, filers should use official forms or electronic filing rather than the informational PDF.
