My understanding is: Verbrauchter Freibetrag [gemäß] §67 [Einkommenssteuergestz] in Abrechnung.
Section 67 of the income tax code defines the tax rates applied to additional benefits an employee receives beside their regular salary. In particular it includes an allowance (Freibetrag) up to which no Lohnsteuer (advance payment on the employee's income tax due payed directly by the employer) has to be payed.
