Does converting crypto on Coinbase get taxed?

I'm curious about the tax implications of converting cryptocurrency on Coinbase. When I decide to sell or trade my digital assets on this platform, am I subject to any taxes? How does the process work, and what factors determine the amount of tax I may need to pay? Is there a specific tax form I need to fill out, or are there any specific rules or regulations I should be aware of when it comes to cryptocurrency taxes in general?
