Prices vary by state. You can see the cost, process, and how long it takes in step four below.
What the process looks like
Third-Party Agent (TPA) authorization reminder
Some state agencies need Gusto to have TPA access to file and pay your taxes. Usually, CorpNet does not set this up, so you’ll have to do it yourself after registration.
Check the state registration articles to see if TPA is needed and how to set it up. If there's no “Authorize Gusto” section, then TPA is not needed right now.

Q: Can I run payroll before my registration is done?
A: Yes, you can usually run payroll before all state tax info is added in Gusto. You may be asked to enter tax rates and tax deposit frequencies, but can use temporary info.
Important reminders
Q: Can I use Gusto to register in a new state without a Federal Employer Identification Number (FEIN)? What if my business is merging or being acquired?
A: No, you need a FEIN in Gusto to get registration help for state taxes.
If your business is merging or being acquired, CorpNet cannot help with registration. You'll need to work with a tax advisor and state agencies directly.
Q: Where can I find my tax information?
A: You can find your tax info in several places:
Gusto’s state tax registration service does not contain tax, legal, financial, or HR advice. Since rules and regulations change over time and can vary by location, consult a lawyer, HR expert, or accountant for specific guidance.
Q: What if I'm not liable for unemployment tax yet?
A: If you want CorpNet to start setting up an unemployment account number before you're liable, you can:
Q: Can CorpNet help if the responsible party is international without an ITIN or SSN?
A: CorpNet might be able to help. Contact them at [email protected] or 1(888) 449-2638.
Q: Why am I unable to enter 0% ownership for the responsible party or add a commercial owner?
A: Some states have a 1% minimum for the responsible party ownership percentage. These states include ID, KS, MN, OH, SC, DC, DE, MD, NJ, NY, and RI.
You’ll need to place registration orders directly with CorpNet outside of Gusto or register directly with the agency.
Some states require an individual owner to be listed. If you’re a non-profit or unsure, contact CorpNet for help at [email protected] or 1(888) 449-2638.
Q: Does CorpNet help with giving Gusto third-party access (TPA) for tax payments?
A: Some state agencies need Gusto to have TPA access to file and pay your taxes. Usually, CorpNet does not set this up, so you’ll have to do it yourself after registration.
Check the state registration articles to see if TPA is needed and how to set it up. If there's no “Authorize Gusto” section, then TPA is not needed right now.
Q: Does CorpNet help close state tax accounts?
A: No, you'll need to close the tax account yourself.
