A zero-percent certificate of indebtedness has a minimum purchase amount of one cent. The only purpose of a zero-percent certificate of indebtedness is to accumulate funds for the purchase of another eligible security in the TreasuryDirect system. A zero-percent certificate of indebtedness within a minor's account is the property of the minor alone. The payroll zero-percent certificate of indebtedness is a restricted form of the zero-percent certificate of indebtedness that is held separately from the zero-percent certificate of indebtedness and used only for purchases made through the payroll savings plan.","path":["Title 31—Money and Finance: Treasury","Subtitle B—Regulations Relating to Money and Finance","CHAPTER II—FISCAL SERVICE, DEPARTMENT OF THE TREASURY","SUBCHAPTER A—BUREAU OF THE FISCAL SERVICE","PART 363—REGULATIONS GOVERNING SECURITIES HELD IN TREASURYDIRECT","Subpart D—Zero-Percent Certificate of Indebtedness"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-31.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:25:25Z","sha256":"db7bb486c75a3e17de5c6437d08c910c72e123dc1d46be84d7671ea94d8acb0e","source_id":"us-cfr","stale":true,"prev":"us/31-cfr-363.130","next":"us/31-cfr-363.132"},"notice":"GroundRules: Original legal text.
