Why is Paypal asking for my tax ID?

If you are selling tickets in the United States, the IRS requires PayPal to issue a Form 1099-K to you when you sell $600 or more in sales across all your events during a calendar year. Selling tickets is considered by the IRS as 'Goods and Services'. PayPal requires you to complete your account set up and enter your Tax ID. 

Please read more about PayPal's 1099-K reporting thresholds. 

Please contact a tax professional for more information on this tax.
