Section 6418 is the IRA rule that makes certain clean energy tax credits transferable, meaning the project can sell the credit for cash to an unrelated buyer with tax capacity. The seller makes a transfer election on its tax return, the buyer pays cash, and the buyer claims the credit on its own return, with the IRS registration and documentation doing most of the heavy lifting. You cannot re-sell the same credit again, and the market lives and dies on eligibility, basis support, recapture exposure, and who writes the indemnity. Net, 6418 turns tax credits into a finance product, simpler than tax equity structurally, still not simple operationally.
