I'm fairly new to selling through Amazon FBA and trying to wrap my head around the tax side of things. I’ve read a lot of conflicting info on forums, and I’m not sure what exactly I need to be doing in terms of income tax, sales tax, and VAT (if selling internationally). 

• Do Amazon FBA sellers need to collect and remit sales tax themselves, or does Amazon handle that now?

• How do you report FBA income—do you treat it like regular self-employment income?

• Any tips for staying compliant across multiple states or countries?

I came across this article that breaks down how to choose an Amazon FBA accountant and why it matters:

It helped a lot, but I’d love to hear from actual FBA sellers—what’s your tax setup like? Any major pitfalls to avoid?
