Voluntary withholding tax application form

The percentage of withholding tax applied to the salary is calculated automatically by the Spanish Tax Agency's program, which takes into account your personal and family situation, as declared in the Model 145 form, the gross pay that you are expected to receive from your employer during the tax year, and the contractual conditions.

The interested person can request a voluntary withholding, as long as this request is higher than that established by the Tax Agency.

You can apply for a voluntary rate of withholding tax through the Service Manager on the UPC Staff Portal: PUC - Personal

The application must specify the percentage of withholding tax that you wish to be applied.

• The voluntary withholding tax will be applied to your next salary payment, provided that the application is made before the 15^th day of the month, except in July, August and December, when it must be made before the 10^th day (July 10th also for August) .
• This percentage will be applied until you request otherwise or until the Tax Agency program calculates a higher one, in which case the latter will be applied.
