Summary

When a company takes an action that changes the cost basis of its stock or other covered securities — something like a stock split or merger — it must report that action to the IRS. The report has to describe the action and spell out exactly how much it changes the basis. It is due within 45 days of the action, or by January 15 of the next year, whichever comes first. The company must also send holders (or their brokers) a written statement with the same information and a contact name, address, and phone number. The IRS can waive these filings if the company instead posts all of the required information publicly.
