Gusto works with Middesk to register your business for state tax accounts when you hire employees or start working in a new state. We set up state income tax withholding and state unemployment insurance so we can run payroll and file taxes on your behalf.
We can start your registration after all of these are true:
You added a company work address in the new state.
You assigned that address to a new or existing employee.
You checked your Gusto Home page for a registration to-do.
If required, you registered with preliminary state agencies (like the Secretary of State or Department of Licensing and Regulatory Affairs) first and confirmed it's done.
States that require SOS registration before tax setup: Michigan, Missouri, New Jersey, New Mexico, and Vermont.
Middesk cannot help with registration if your business is:
A non-profit that is not a 501(c)(3)
A business that left a PEO
A business that bought another business that was already registered
A business that changed its legal entity type (for example, LLC to Corp)
A Limited Partnership (LP) or Limited Liability Partnership (LLP)
You must also:
Have a FEIN in Gusto
Not already have a tax account in that state
If you already registered with the state, Middesk will cancel the order and you will not be charged.
Included
Middesk registers your business for:
State income tax withholding
State unemployment insurance (SUI)
Not included
Middesk does not register your business for:
Local tax agency registration
Paid Family and Medical Leave (PFML) registration
Third-Party Agent (TPA) access
Power of Attorney (POA) authorization
Some states require TPA or POA for Gusto to file and pay taxes. In most cases, you must set this up yourself after registration. If you need to register for local taxes or PFML, or set up TPA or POA, use the state-specific article for step-by-step instructions.
The cost, steps, and timeline depend on the state. Before you submit anything in Gusto, we show you:
The price
What is included
How long registration usually takes
You are not charged until the order is marked as completed. The charge appears on your next Gusto monthly invoice.
You can also visit the Middesk Help Center to see estimated processing times for each state.
Here is what to expect when Middesk handles your registration:
You answer questions about your business, including:
Basic company info
Contact details
Addresses
Owner or officer info
State-specific details
Middesk reviews your information.
Middesk usually submits your registration within two business days.
A state agency may contact you to verify the request.
⚠️ Important: If you do not respond to a verification call or email within 3–5 business days, the order may be canceled and refunded.
After your order is marked as complete, we add the charge to your next Gusto monthly invoice.
When Middesk receives your tax account numbers, they enter them in Gusto (for most states and agencies). You will get emails from Gusto and Middesk with updates and next steps.
For most states, Middesk receives agency mail during registration and adds your tax info to Gusto. You can view this mail in a digital mailbox. After registration is complete, the agency updates its mailing address to your business address. If you need to take action, we will notify you by email or Home page to-do.
States that mail tax account info directly to your business: Alabama, Arizona, Delaware, Idaho, Iowa, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Oklahoma, Rhode Island, Washington, Washington DC, and West Virginia. When you receive the letter, check your email for instructions on how to send the info to Middesk.
You can run payroll before registration finishes. However:
Gusto cannot file or pay taxes until all tax account numbers are added.
You may receive late notices or penalties. These are your responsibility.
For unemployment tax, use your state’s new employer rate until you receive the correct one.
Note: You can cancel orders before they are sent to Middesk. Once an order is submitted to Middesk, it cannot be canceled or refunded.
If you need help with any of the registration questions, check Middesk’s Help Center.

Q: Do I need a FEIN to use Gusto’s registration service?
A: Yes. You must have a FEIN to register through Gusto. If your business is merging or being acquired, Middesk cannot help with registration.
Q: Why can’t I enter 0% ownership or add a commercial owner?
A: Some states require a minimum ownership percentage or an individual owner. If your situation does not meet state rules, you will need to register outside of Gusto.
Q: What if the responsible party is international without an SSN or ITIN?
A: Middesk cannot help in this case. You will need to register directly with the state.
Q: What if I’m not liable for unemployment tax yet?
A: Use today’s date or the expected liability date. Use the new employer rate until you get your company-specific rate.
Q: I need to change information I already submitted. What do I do?
A: Email [email protected].
Q: What if the tax agency contacts me?
A: Respond right away, within 3–5 business days. Missing a verification call or email can cancel your registration order.
Q: When will my tax account numbers be available?
A: Timelines vary by state. Check Middesk’s guidance for estimates.
Q: Can Middesk close my state tax accounts?
A: No. You must close accounts directly with the state.
