You have to enter your SSN or your business tax ID in order to receive commission payouts through Paypal or convert your commission to a voucher.
We need this for tax purposes and if you transfer over $599 in commission, to your PayPal account, throughout the year we will send you a 1099 for you to file taxes with. We still need your SSN or business tax ID even if you have not earned over $599 in commission. Converting commission to gift vouchers does NOT count toward the $599.
If you need to update or change your W9 information you can go to your E-Wallet and click on "Change my W9 information".
