I’m experiencing the exact same issue. I’m a non-U.S. individual and the sole owner of a U.S. single-member LLC, and App Store Connect is only showing Form W-9 instead of the appropriate W-8 workflow. I contacted Apple Finance/Tax Support and I have now been waiting for almost two weeks without a resolution. Has anyone here recently had this fixed? If yes, how long did Apple Finance take to respond, and did they send you a secure link to submit the W-8 form? This issue is currently blocking my Paid Applications Agreement. Any recent experience would be really helpful.
