The short answer
Magento's native tax uses rate tables you maintain by hand. Zamp's extension calculates tax in your cart and admin, and our team handles registrations, filings and notices for one price.
Your store keeps running on Magento. The rate research, the filings and the state letters move to us.
Zamp picks the rate from the delivery address, not the ZIP code, so a ZIP that crosses city lines still gets the right tax. When a rate changes, our team updates it. Nobody imports a CSV again.

Yes. A specialist reviews where you sell and where you may already owe. Then we agree a path with you, from filing past-due returns to a voluntary disclosure or registering going forward, and our team does the filing.
