Lind, Lathrope, and Field's Fundamentals of Federal Income Taxation, Cases and Materials, 21st

This widely-adopted casebook provides detailed coverage of federal income taxation, with specific assignments to the Internal Revenue Code, selected cases, and regulations and rulings from the Internal Revenue Service. The revised and updated Twenty-First Edition retains the book’s long-standing format and much of its prior materials, but it is revised to reflect recent legislative, judicial, and regulatory developments. These revisions include updates to provide coverage of the tax legislation enacted into law in 2025 under the title “An Act to provide for reconciliation pursuant to title II of H. Con. Res. 14,” Pub. L. No. 119-21, and more popularly known as The One Big Beautiful Bill Act (the “OBBBA”).
