Your mid-year sales tax checkup

Get compliant before the holiday rush

On-demand webinar

The second half of the year moves fast for e-commerce sellers. Sales volume climbs, filing frequencies shift, and new nexus thresholds get crossed without warning. In this on-demand webinar, former state tax auditors, Senica Ambers and Katherine Martinez, share what to expect and how to stay ahead of it.


What you'll learn:
  • How to map your nexus footprint and avoid the compliance gap that comes with crossing a threshold unprepared
  • What sales tax holidays actually require from retailers (it's more complicated than the name suggests)
  • Why July is one of the busiest filing months of the year and how to get ready for it
  • What the holiday sales rush means for your nexus exposure and filing frequency
  • Where AI helps in sales tax compliance and where human expertise still matters
