How to Obtain Tax Exemption for Wholesale Purchases as an Amazon FBA Seller?

I recently started Amazon FBA and discovered that I have to pay taxes every time I purchase from a wholesaler, which significantly cuts into my profit margins. As a retailer, I understand that I’m not supposed to pay taxes on products I’m reselling—consumers should be paying those taxes when they buy the product.

Is there a way to get a tax exemption when buying wholesale? Do I need any specific permits, licenses, or documents to qualify for this exemption? Any advice or guidance would be greatly appreciated!
