What are tax-free reorganizations, and which M&A structures qualify?

Tax-free reorganizations defer immediate tax on a transaction if statutory requirements are met. Structures may include mergers, share-for-share exchanges, contributions, spin-offs, or internal reorganizations depending on jurisdiction. Requirements usually include continuity of ownership, business purpose, qualifying consideration, and holding-period rules. In M&A, they reduce tax leakage but add legal complexity and restrictions.
