Why Zamp for Walmart.

Counted toward nexus.

Marketplace sales count toward economic nexus in most states, including California and Washington, even when the marketplace collects the tax.

Reported where states require it.

States like Washington and Texas still expect marketplace sales on your return. Zamp reports them, and you don’t pay that tax twice.

Tax codes that hold up.

Walmart calculates from the tax codes you assign, and sellers can be liable for wrong ones. Zamp’s team reviews them with you.

A team that owns the outcome.

U.S.-based sales tax specialists handle registrations, filings, remittance and state notices, with your approval at each step.

Everything you need for global sales tax — in one place.

Does Walmart collect sales tax for me?

In marketplace facilitator states, yes. Walmart.com is the marketplace facilitator and taxpayer of record, but it calculates local tax from the tax codes you assign to your items.

Do Walmart sales count toward economic nexus?

In most states, yes. California and Washington count marketplace sales toward their thresholds; a few, such as Arizona, leave them out. Zamp applies each state’s rule.

Do I still have to report Walmart sales?

In some states, yes. Washington and Texas, for example, expect marketplace sales on your return. Zamp reports them where required, and you don’t owe tax the marketplace already collected.

How do Walmart sales get into Zamp?

Through your Shopify store’s Walmart Marketplace app or Marketplace Connect, an upload of Walmart’s Tax Remittance Report or the Zamp API.
