Sales Tax Nexus & Registration
Review where your business may need to register, collect, and file sales tax.
Online service across all 50 states

What this service is
Since the 2018 Supreme Court decision in South Dakota v. Wayfair, a business can owe sales tax in a state simply by selling enough there, no office or employees required. Each state sets its own sales threshold and decides which products and services are taxable. We find out which states you have crossed the threshold in, confirm what you sell is taxable there, register you, and then file the recurring sales tax returns, while reconciling sales made through Amazon, Etsy, or other marketplaces that already collect tax for you.
