Cal. Gov. Code § 59511

If a reassessment has been levied upon tax-deeded land and upon the recordation of the reassessment, the clerk shall send to the auditor of the county in which the land lies notice that the original bonds of the district have been refunded and that the unpaid taxes and special assessment taxes levied to pay the principal and interest of such bonds are canceled. The auditor shall compute the amount of the unpaid taxes and special assessment taxes, penalties, and interest so canceled and notify the State Controller of the amount. The amount shall be deducted from the amount necessary for a redemption of the property.
