Intermediate Quick Answer
What is the SST unified registration, and how many states does it cover?
⚡ TL;DR
The SST unified registration is one free application, submitted through a Certified Service Provider, that registers you in all 24 SST member states you select. It replaces 24 individual DOR applications. California, Texas, New York, Florida, and other large non-SST states still require separate registration.
The SST unified registration is one application that registers you in all 24 SST member states at once. Filed through a Certified Service Provider, it’s free and replaces 24 individual DOR applications. It’s one of the most operationally significant features of the SST program for multi-state sellers.
Key takeaways
- One application through the SST Registration System (SSTRS) registers a seller in up to 24 states simultaneously
- The registration is submitted through a Certified Service Provider — TaxCloud and other CSPs handle submission on the seller’s behalf
- There is no registration fee for SST states through a CSP
- The seller selects which SST states they have nexus in; they’re not automatically registered in all 24, only the ones they identify
- Non-SST states (CA, TX, NY, FL, IL, PA, and others) require separate, individual registration through each state’s DOR portal
- Once registered, the CSP files returns on the seller’s behalf in all SST states each month: the seller doesn’t interact with 24 separate state portals
