Due to IRS reporting rules, Sovrn //Commerce will not be issuing any IRS Form 1099s for amounts paid to publishers (unless Sovrn //Commerce paid you directly by check, ACH, or wire, rather than through PayPal). Instead, all IRS reporting (if any) will be done by PayPal.
As such, you should log on to your PayPal account to determine if you will be receiving a Form 1099-K from PayPal. Please note you are obligated to report income you receive, whether or not that income is reported on a Form 1099 or another tax report. Sovrn //Commerce is not able to provide you with any tax advice. Sovrn //Commerce recommends that you consult your own tax advisor.
