General Registration FAQs
What are the benefits of registering under the SSUTA?
When you register through the Streamlined Sales Tax Registration System (SSTRS):
You may register in all Streamlined States or just selected states with one application.
You can end registrations in selected states or all states, and if needed register in a state with a couple quick clicks.
You may receive amnesty in certain states, subject to limitations.
You may use a Certified Service Provider (CSP). These services may be provided free to you in states in which you are a
"CSP-compensated seller."
You may use a Certified Automated System (CAS).   A seller using a CAS is entitled to compensation from the sates in which it qualifies for the first twenty-four months.
You can update your registration information for all Streamlined States in which are registered for through the SSTRS.
What does it mean to register through the Streamlined Registration System (SSTRS)?
This SSTRS is a quick and easy way for you to register for sales and use tax accounts in Streamlined States.
When you register through the SSTRS, the registration information is sent to the states you select. The states will issue your business a sales tax account for collecting and remitting sales tax.  Once registered you will be required to collect and remit sales and use taxes for all taxable sales into those states.
Am I required register for a sales or use tax using the SSTRS?
No, Only those sellers that want the benefits of the SSUTA must register through the SSTRS.
Article III, Section 303  SSUTA
May I use the SSTRS even if I have a legal obligation to register in a state?
Any seller that wants or needs to register in any of the Streamlined States may use the SSTRS.
States may require additional information if you have a legal obligation to collect a state's sales tax if you are not already registered in that state.  If a state needs additional information, they will contact you.
Can I select the states that I want to register for?
Yes,  You can register in all Streamlined States or in the states you select.   You can add registrations for additional states as needed.
My company is already registered in some states, how will this affect my registration?
If you are already registered in a state, you may still use the SSTRS.
Simply check the box next to the state(s) indicating you are "Already Registered."
This information will help prevent states from issuing duplicate registrations. Most states will just add your Streamlined Sales Tax ID (SSTID) to your current account.
Does registering through SSTRS remove my prior tax liability?
Except for states offering amnesty (currently only TN), registration through the SSTRS does not eliminate any prior tax liability if you were legally required to be registered.
Contact that state
for questions concerning prior tax liabilities.
Will you be notified if a state becomes a new Streamlined Member state?
Yes, if registered through the SSTRS you will be notified if there are new states you can register for through the SSTRS.
Email notices will go the contact person's email on your registration.  Be sure to keep this information updated.
What is an Associate Member State?
An Associate Member State is a state that the Streamlined Sales Tax Governing Board has determined to: (a) either be in compliance with the SSUTA, except that changes to their statutes and rules are not all in effect at this time; or (b) in compliance with nearly all parts of the SSUTA.
Tennessee is the only Associate Member State at this time.
Article VIII, Section 801.3  SSUTA and Article III, Section 303, H  SSUTA
Will a Streamlined state have access to my registration information if I do not register for that state?
When you register through the SSTRS, your registration information will only be transmitted to those states in which you elected to register.

Questions to ask before you register
Do you have a requirement to register to collect and remit sales tax in a state?
If you are unsure if you are required to collect and remit sales tax
contact that state
to determine your requirements.  You may also review information on the state’s website and
Remote Seller
Marketplace Seller
, and
Marketplace Facilitator
State Guidelines.  Links to this information are available on each state’s information page.
Sellers that are not required to register may still choose to register and collect and remit sales tax.
If you register through the Streamlined Registration system you will be registered in each Streamlined State you select and will be required to collect and remit sales tax in each of those states.
Do you agree to collect and remit sales tax, but you do not sell and deliver products in some of the states?
If you do not have sales that are sourced (delivered) into a Streamlined State but agree to collect sales tax in the states in which you have sales, you can register using the SSTRS.
You can select the states that you need to be registered in.  If you meet the registration requirements in another state at a later date, you can add that states registration then.
Do you need help with your sales and use taxes?
Contact a Certified Service Provider (CSP) to discuss the services they provide under their contract with the Streamlined Sales Tax Governing Board.   If you choose to contract with a CSP, the CSP will register your business for you.
The CSP will provide the software and services necessary to:
Set-up and integrate its Certified Automated System (CAS) with your system;
Calculate the tax due on a transaction at the time of the sale;
Prepare and file the required returns;
Make the necessary remittances;
Respond to and provide supporting documentation with respect to sales and use tax notices and audits; and
Protect the privacy of tax information it obtains for that state.
Who can use a CSP:
Any seller registered through the Streamlined Registration system. The CSP will provide services for all Streamlined States you are registered for through the SSTRS.
Cost:
Under the CSP contract, the CSP will not charge you for these services provided for your business in the Streamlined States in which you qualify as a “CSP-compensated seller.”  (
Do you qualify for Free Services?
A CSP may charge for services in states in which you are not a CSP-compensated seller and for services beyond the services required by the CSP contract.
Not a "CSP-Compensated Seller":
CSPs provide services to all types of sellers and may provide services in states that are not Streamlined States.
Learn More about CSP services
Do you want an exemption from sales or use tax on your purchases?
Any business that is looking for an exemption from sales or use tax on purchases for their use, must contact the state directly to determine if they qualify for exemption.
Registering through the SSTRS provides a license or permit to collect and remit sales tax.  It does not provide an exemption from sales or use tax on the entity's purchases for their use.

How to register
Are you going to use a Certified Service Provider?
If you are going to use a Certified Service Provider (CSP),  let the CSP register your business.
If you need to register and begin reporting before the date the CSP will begin services for your company, you can register at anytime.  When you register select the CSP you plan to contact.  The CSP will update your account to show when their services begin.
Not contracting with a Certified Service Provider?

www.sstregister.org
What is the "Registration Date?"
The Registration Date is the date the seller wants this registration to begin for that state. The state will expect the seller to collect and report sales tax beginning on this date.
If the seller is already registered in a state and is now registering for that state through the SSTRS, the seller should use the current date as the registration date.
The Registration Date does not reflect the date the seller became liable for sales tax in a state and does not remove liability for taxes the seller may owe prior to registration.
If you owe sales tax for periods prior to your registration date, please contact the state to determine how to report those taxes.
Can I set a future date for my registration to begin?
Yes, When you register you can select a date for your registration to begin for each state (registration date).  This date may be up to the first day of the calendar month that is no more than 60 days in the future.
States will expect you to begin collecting and remitting sales tax on the date you select.
Selecting a future registration date does not remove liability you may have for past sales in that state.

What to expect after registration
State registration and reporting information
When you submit the registration, you are issued a SSTID and are registered in each state you selected.
Most states will send registration and reporting information within 15 days after you register.
Some states may require additional information to complete your registration, such as corporate officer information.  The state will let you know if additional information is needed.
Will I receive a tax ID number for each state?
A Streamlined Sales Tax ID (SSTID) is issued when you submit your registration through the SSTRS.  That number is a 9-character ID starting with a "S."  You may use your SSTID for communications with Streamlined and all Streamlined Member States.
A state may use the SSTID for filing of returns, however, most states will provide you a state issued number to use.  Each state should let you know your reporting requirements.
Filing and paying sales tax
1. Did you contract with a CSP?
If you contracted with a CSP, the CSP will file the sales tax returns and remit the sales tax for you each month to each Streamlined states you are registered in through the SSTRS.
2. Filing your returns
If you did not contract with a CSP, you are responsible for filing the sales tax returns with each state using their online filing systems.  The state’s registration letter will have information as to how frequent you will need to file the returns.
All states in which you are registered expect you to file returns each reporting period even if you have no tax to report.   You are required to file returns even if you no longer meet the Remote Seller Threshold for that state.  If you no longer meet the Remote Seller Threshold contact the state to determine if you can cancel your registration.
Some states may have you file as needed or on a "casual" filing basis. That means you file when you have sales.
If you registered prior to February 11, 2019, and you indicated you did not have sales in a state when you registered, but you now have sales, contact that state to have them set your account up to accept returns.  You are registered in the state and will not be required to re-register.
Do not ignore notices from a state.
If you do not understand why you received a notice, contact the state as soon as possible to discuss.
No longer have sales in a state, but you are still selling in other states?
If you do not sell or delivery products in a state and do not have a registration requirement for that state, you may end your registration through the SSTRS for that state.
States will expect you to file sales tax returns for the period you were registered.
Contact the state to determine your registration requirements.
Did you indicate no sales in a state when you registered, but now you have sales?
Contact the state
to set up your account for reporting.  If you registered prior to 2/11/2019, you were automatically registered in all Streamlined Full Member States when you registered. You will not need to re-register for that state.
You cannot change the indicator for "Has Sales" after you register.
Is there a fee to register through the SSTRS?
There are no fees or other charges to register in a state in which you have no legal requirement to register.  Some states may charge a fee if you have a legal requirement to register. If those states require a fee, they will contact you.
Article III, Section 303.C
Will states request additional information?
States may require additional information if you have a legal obligation to collect a state’s sales tax if you are not already registered in that state.  If a state needs additional information, they will contact you.
