Summary

The Secretary can make a written agreement with anyone about how much federal tax they owe for any tax year. If the Secretary approves the agreement in the time the agreement allows (or later agreed), the agreement becomes final and binding. Except if someone proves fraud, serious wrongdoing, or that an important fact was lied about, government officials cannot reopen or change what was agreed, and courts or other proceedings must honor the agreement and any related tax actions (like assessments, collections, refunds, or credits).
