Tax information CPAgrip

I've just joined CPAgrip and it's asking me to submit tax info. Do i need to do that in order to get paid or can i just leave it blank? Thanks in advance

 

you need to fill the form if you want to get paid

 

Thanks for reply mate

 

You can always fill it out at a later date.

It is crazy that you have to fill it out in order to receive commissions so if you would prefer to avoid paying just work for a foreign network and claim it manually.
