Sales Tax Exclusion (STE) Proposed Regulations/Current Regulatory Actions

On Friday, January 30, 2026, at 10:00 AM, CAEATFA will be discussing proposed amendments to the Sales and Use Tax Exclusion Program’s regulations at a public workshop. The public workshop will be held remotely via Microsoft Teams.

The proposed amendments will address the statutory requirements of SB 86 (McNerney, Chapter 211, Statutes of 2025), policy and compliance adjustments, and opportunities to streamline program administration while introducing greater flexibility to meet program needs. CAEATFA staff will also address additional changes, including fee-related adjustments aimed at improving program efficiency and effectiveness.  

CAEATFA invites public comments during the workshop and by email to steprogram@treasurer.ca.gov until 5:00 PM on Friday, February 6, 2026. To participate in the remote workshop, please register by going to the remote workshop registration page.
