Wyoming Resale Certificate for Amazon FBA Sellers

Hi fellow sellers,

I need some guidance on getting a resale certificate for my wholesale purchases.

My situation:

LLC registered in Wyoming (no physical office/warehouse/employees there)

Purely online e-commerce business selling on Amazon FBA

Wyoming Department of Revenue says they won’t issue me a sales tax permit or resale certificate because I don’t have nexus in Wyoming

My question:

Since Wyoming won’t give me a resale certificate, which state should I register in to get a valid resale permit for buying inventory tax-free from wholesalers?

My inventory moves around in Amazon FBA warehouses

Has anyone else with a Wyoming LLC faced this? What state did you use for your resale certificate?

Any advice would be really helpful. Thanks!
