German to English Bus/Financial Law: Taxation & Customs Non-cash benefit tax

This appears in a company brochure outlining a car lease model to employees as part of a salary sacrifice scheme.
In a section dealing with the income tax implications for an employee leasing a car via a leasing company, where the employer pays the lease and the employee sacrifices a salary amount, it is explained how the employee's taxable salary is reduced by the lease payment amount, the insurance premium and other costs BUT it is also increased by the amount equal to that of the taxable value of the non-cash benefit (i.e. the car lease).

My sentence reads:
"Der steuerpflichtige Arbeitslohn wird dagegen in Höhe des für die PKW-Gestellung zu versteuernden geldwerten Vorteils erhöht. (Zur Berechnung des geldwerten Vorteils s. Anlage 3)"

My translation thus far:
"The taxable salary is however increased by an amount equal to that of the taxable value of the non-cash benefit (i.e. the provision of the car.) (To calculate the value of the non-cash benefit, see Appendix 3)."

I am concerned about the wording "taxable value of the non-cash benefit". Is anyone able to confirm that the sense of my translation of this phrase is OK?

Many thanks.
