Sales tax for SaaS: the nexus question in plain terms

Software companies often owe sales tax in states where they have no office and no staff. The trigger is usually revenue, not presence.

Sales tax for SaaS: the nexus question in plain terms

Since states began taxing remote sellers based on sales volume, a SaaS company can create a filing obligation simply by selling to customers in that state. Many founders find out during diligence.

How the trigger works

Each state sets its own threshold, usually a revenue amount or a number of transactions within a year. Not every state taxes software, and the rules differ between downloaded software and software as a service.

What we do every quarter

  • Map revenue by customer billing address
  • Compare it against each state's threshold and taxability rules
  • Register before the threshold is crossed, not after
  • Set up collection in your billing tool and file returns on schedule

Thresholds and rules change. Treat this as an overview and confirm with a sales tax specialist for your states.
