Streamlined Sales Tax Registration System (SSTRS)


The SSTRS is a quick and easy way for sellers to:

  • Register for sales and use tax accounts in all Streamlined States or just the states you select by completing a single application
  • Register in additional Streamlined States when needed
  • Update business and contact information for all states registered in through the SSTRS
  • End registration in Streamlined States
  • Reregister in a Streamlined State if needed

What this registration is for:  A permit or license to collect and remit sales and use tax.  Contact the state for other licensing requirements and other taxes you may owe.

Who can register:  Any seller may register, even if you are already registered in a state.

Who must register through the SSTRS:  Any seller that wants to contract with a Certified Service Provider (CSP). The CSP will provide services for each Streamlined State you are registered in through the SSTRS. 

Cost: There is no fee to register through the SSTRS. (Note: A state may charge a fee if you are legally required to register in that state.)


You are required to register in each state in which you have met the physical or economic nexus standards or any other requirement of the state. You may register directly with the state or through the SSTRS.

Registration does not remove any liability for taxes that may be due for sales prior to this registration.

Contact the state to discuss your registration requirements and any prior tax liability.
