The short answer

Does Adobe Commerce file your sales tax?

Not on its own. Adobe Commerce applies the tax rules you configure. Zamp's extension calculates rooftop-accurate tax at checkout and applies B2B exemptions, and our team registers, files and pays every state.

Adobe Commerce tax that holds up at scale.

Real-time calculation in your storefront and admin, and a managed service for everything after the order.

Every cart taxed at the rooftop.

The rate comes from the delivery address, not the ZIP code, and it's the same in the cart, at checkout and on orders your team creates in the admin. Bundled, configurable, virtual and grouped products are taxed line by line.

Explore calculation

B2B exemptions applied before the invoice.

Mark a buyer, or a whole customer group, exempt once and Zamp applies it at checkout. A buyer's own code wins over the group's, so exceptions stay exceptions. Add exemption certificate management and we also read and track every certificate.

Explore exemptions

Returns filed and notices answered for you.

Each period you review liability by state and approve. We file and pay on every state's schedule, and when a state writes back, our team answers it.

Explore notice management
Multi-channel

Every website and channel in one view.

DTC storefronts, B2B portals and other channels roll up into one set of returns and one nexus view. Each website and store view is supported, so a new brand or region doesn't mean a new tax setup.

Not just a tool. A sales tax team.

Every Zamp subscription is a managed service. The platform calculates and tracks, and our tax specialists register, file, remit, and answer the state.

How does Adobe Commerce tax calculation work natively?

Adobe Commerce calculates tax from rules and rates you maintain. Each tax rule combines a product tax class, a customer tax class and the rates you enter or import by ZIP code or range1, 2. It doesn't research or update rates for you, or file returns, which is why most US sellers add a tax service.

What happened to Vertex in Adobe Commerce?

Vertex shipped with Adobe Commerce 2.4.0 through 2.4.3 and was removed from the core release in 2.4.43. Since then, any tax service is installed and updated from the Commerce Marketplace3. Zamp's extension is one of them, and it comes with a team that registers, files and answers the state for you.

How does Zamp handle B2B tax exemptions in Adobe Commerce?

Zamp applies exemption codes set on a customer or a customer group at checkout. If both are set, the customer's own code wins. With exemption certificate management, Zamp also reads each certificate, files it against the buyer and tracks every state it covers.

Can Zamp handle multiple Adobe Commerce websites and store views?

Yes. Each website and store view is supported, and transactions from all of them roll up into one set of returns and one nexus view.

Does Zamp file and remit Adobe Commerce sales tax?

Yes. Our team prepares each return, you review and approve, and we file and pay each state by ACH. We also register you in new states and answer notices.

What happens if a Zamp calculation is wrong?

The Zamp Commitment covers it. If an inaccurate Zamp result triggers a state audit, we cover the uncollected tax, penalties and interest, up to what you paid Zamp over the prior 12 months, on the Commitment's terms. If we cause a late filing, we cover the penalties and interest.

How is Zamp priced for Adobe Commerce?

One price based on your monthly order volume and the number of states you file in. Registrations are included, and calculation calls at checkout aren't metered.

We already use a sales tax provider with Adobe Commerce. How do we switch to Zamp?

Most teams switch at the end of a filing period. We move your existing registrations, filing calendar and Adobe Commerce history over, your current provider files its last period and Zamp files the next, so no return is missed or filed twice. If you're mid-contract, ask about the Zamp buyout.

We haven’t been collecting or filing sales tax everywhere we should. Can Zamp help us catch up?

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.
