Sales tax reporting software for e-commerce and Amazon FBA sellers in the United States

  • Founded 2018

About EcomTax

EcomTax prepares sales tax figures for online sellers, with a strong focus on Amazon FBA businesses. It connects to a marketplace account and turns the seller's sales data into state-by-state reports that can be used to file returns.

What EcomTax offers

  • Return-ready reports — sales tax reports built separately for each state, with state and local detail for filing.
  • Marketplace integration — a single-step link between a seller's marketplace account and the software.
  • Nexus alerts — warns sellers when inventory moved between fulfilment centres may have created a tax obligation in a new state.
  • Cloud reporting — hosted service that scales across large and small seller accounts.
  • Fulfilment centre map — a reference map showing where Amazon warehouses are located, to help sellers see where stock sits.

Who it works with

The service is built for e-commerce sellers, especially large and small FBA business owners who sell across several US states and need to keep track of where they owe sales tax.
