Yes. All players who win more than $600 in a calendar year will be required to fill out and submit a W-9 form. ClubWPT will then issue players who have won more than $600 a 1099 form to submit and complete their taxes. This is in line with Federal Tax Regulations and is required.
If you would like to submit a W-9 ahead of time, you can complete the form at any time to expedite the process when the time comes to send your 1099 tax documentation.
