Cassa Prep guides software sellers through a browser-based decision flow about California tax treatment under SB 122.

Landing page captured for the 2026-09-25 issue.

For: Indie and self-serve software sellers
Worth noticing: It marks AI products as a borderline case and says CDTFA guidance is still pending.

Field notes

The flow separates prewritten software and SaaS from custom builds, infrastructure, and several excluded digital-product categories. It then asks about California nexus and receipts, including a $500,000 threshold and a $5 million carve-out. The page says the decision flow runs locally in the browser; it also calls some AI offerings borderline while awaiting further guidance.
