Galaxy Sports will never take any taxes from your withdrawals and does not report your transactions to any financial institution or government agency. As a player, it is your responsibility to abide by your local laws and pay all taxes accordingly.
As we are sure you can appreciate, Galaxy provides service to customers from around the world and in many US states so it would be impossible for us to accurately provide you with information relating to your local tax laws.
We ask that you please inquire with your local tax authority or a certified tax attorney regarding any obligations you may have to pay taxes.
