Verified steps
Confirm economic or physical nexus in one or more Streamlined Sales Tax member states before registering
Submit a single free application at sstregister.org, selecting either all Streamlined member states or only the specific states requiring registration
Note that registration applies going forward from the registration date and does not waive any pre-existing tax liability in a state
Engage a Certified Service Provider (CSP) for automated tax calculation, return preparation, and remittance across the registered member states
Await per-state confirmation of registration and reporting information, typically issued within about 15 business days
Known gotchas
SSTRS covers only Streamlined member states, not all US sales-tax states - non-member states such as California and Texas require separate direct registration
Returns must still be filed in each registered state for every period, even with zero sales
