Purpose
Form 1099-CAP reports changes in corporate control or substantial capital structure modifications. For 2023, you must report the date of exchange in Box 1, aggregate consideration received in Box 2, share count in Box 3, and stock classes involved in Box 4. Shareholders report gains—but NOT losses—on Form 8949 per Publication 550, Chapter 4 rules applicable to 2023 transactions.
Filing Steps
Obtain Shareholder Taxpayer Identification Number
You must obtain the shareholder's complete Taxpayer Identification Number, which may be an SSN, ITIN, ATIN, or EIN, and verify against IRS records. Copy B disclosure limits display to last four digits only for shareholder protection under 2023 identity-theft guidance, though full TIN must be reported to IRS.
Identify Exchange Date
Enter the exact calendar date the exchange occurred in Box 1. The 2023 instructions require this date to match corporate records and control-change documentation reviewed for Section 368 or related reorganization eligibility.
Calculate Aggregate Amount Received
Calculate the aggregate amount received in Box 2 as the combined fair market value of all cash, stock, and other property exchanged. Shareholders for 2023 must understand that this amount does not permit loss recognition, a restriction unchanged but emphasized in current shareholder warnings.
Count and Verify Share Count
Record the total number of shares surrendered in Box 3. Reconcile against shareholder account records and the corporation's cap table to prevent reporting discrepancies flagged in 2023 compliance reviews.
Identify Stock Classes Exchanged
List all classes of stock exchanged in Box 4, including common, preferred, or convertible classes. Note if multiple classes are involved in a single transaction to clarify the basis calculation for shareholder Form 8949 reporting in 2023.
Complete Shareholder Information Section
Provide the shareholder's name and address with the current mailing address. The 2023 instructions require address matching IRS records to avoid backup withholding triggers under Section 3406.
Assign Account Number
You may assign an account number if you maintain unique identifiers. The 2023 guidance permits the use of internal reference codes to link shareholder records across multiple exchanges or sequential restructurings.
Prepare Required Copies
Prepare Copy A for IRS, Copy B for shareholder delivery by January 31 of the following year, and Copy C for your records. The 2023 filing requires a concurrent Form 1096 transmittal with aggregate shareholder count and total consideration reported.
Verify Corporation Information
Confirm your corporation TIN and name match the EIN registration. You must verify no name changes post-restructuring that would cause IRS matching failures for 2023 filings.
Review Reorganization Qualification
Review Publication 550, Chapter 4 (2023 edition) to confirm whether the exchange qualifies as a reorganization under Section 368. Nonqualifying exchanges may trigger different gain-recognition timing than reorganizations.
Cross-Reference Form 8949 Instructions
Cross-reference Form 8949 instructions for 2023 to advise the shareholder that gains only are reported there. Losses cannot be claimed based on the Box 2 amount per explicit form language.
Retain Supporting Documentation
Retain supporting documentation, including closing statements, stock certificates, and valuation reports, for at least 3 years from the due date of the returns or maintain the ability to reconstruct the data. The 2023 procedures follow standard IRS retention requirements for information returns.
2023 Year-Specific Changes
Shareholder Copy Warnings
Shareholder copies for 2023 explicitly warn that gains must be reported and losses cannot be claimed. This language reflects a consistent IRS position on nonrecognition limitations tied to control-change exchanges.
Current Form Instructions
Form 1099-CAP instructions follow the continuous-use revision system applicable to 2023 and subsequent years until a superseding revision is issued. IRS updates to Publication 550, Chapter 4 (2023 version), apply to reorganization qualification rules.
Fair Market Value Determinations
Box 2 fair market value determinations for non-cash property follow 2023 Section 1031 and Section 1036 valuation standards. Appraisals of illiquid securities must reflect contemporaneous documentation.
Identity Protection Protocols
Identity-protection protocols requiring the last four digits of TIN on Copy B continue under 2023 IRS safeguards. Full TIN must be filed with Copy A to the IRS Center without masking.
Filing Deadline Rules
No special COVID-19 administrative extensions or penalty relief apply to 1099-CAP filing for 2023. Standard January 31 deadline and Form 1096 transmittal rules govern 2023 filings.

Acquisition of Control Definition
An acquisition of control occurs when the second corporation gains control after not having control before the stock acquisition. The FMV of the stock acquired must be $100 million or more, shareholders must receive stock or other property pursuant to the acquisition, and the first corporation or any of its shareholders must be required to recognize gain under section 367(a).
Control means ownership of stock possessing at least 50 percent of the total combined voting power of all classes of stock entitled to vote. Control also means at least 50 percent of the total value of shares of all classes of stock.
Substantial Change in Capital Structure
A change in capital structure occurs when reporting entities provide $100 million or more in cash or other property to shareholders through mergers, consolidations, asset transfers, bankruptcy proceedings, or changes in corporate identity, form, or place of organization. Either the corporation or any of its shareholders must be required to recognize gain under section 367(a) as a result of the transaction.
