Withdrawal, discharge, subordination, release
These four words get used interchangeably and they are not the same thing. A release ends the lien once the debt is satisfied or becomes unenforceable. A withdrawal removes the public notice, which can be available while a balance still exists, for example after entering certain payment agreements. A discharge lifts the lien from one specific piece of property so a sale can complete. Subordination moves the IRS behind another creditor so a refinance can proceed.
Choosing the wrong one wastes weeks. Somebody trying to close a house sale needs a discharge, not a withdrawal, and the application has its own timing requirements that do not fit comfortably into a normal closing schedule.
