Information Required to Process Payments

Hi,
Recently i got an email from payoneer. It says:

"Thank you for choosing Payoneer as your payment solution for receiving funds from CROSSOVER.

As CROSSOVER is required by law to deduct taxes when making payment, it is necessary for you to submit the relevant tax form. On behalf of CROSSOVER, we kindly ask that you use the link below to locate and submit the appropriate form. We recommend that you do this as soon as possible in order to avoid any unnecessary delays in payment. "

I do not use crossover for two years and switched to upwork 2 years ago. Is is required to submit tax form ? In my country online freelance does not require tax being paid.

Also, is there a way to remove crossover from my funding source ?
