Do I have to pay sales tax if I buy crypto?

As a cryptocurrency investor, I'm always curious about the tax implications of my transactions. Could you please clarify, do I have to pay sales tax if I purchase cryptocurrency? I understand the complexities of taxation in the digital asset space, but I'm particularly interested in understanding whether a standard sales tax applies to these types of purchases. Your expertise in this area would be greatly appreciated as I strive to remain compliant with all relevant tax regulations. Thank you for your assistance in clarifying this matter.
