Idaho registration and tax info

What you need to do

• Add a new work address in Gusto for a different state, and;
• Hire an employee and assign them to that address.

Cost and timeline

Prices vary by state. You can see the cost, process, and how long it takes in step four below.

What the process looks like

1. You give us some basic business information.
2. Gusto and CorpNet will check your info.
3. Your registration is usually submitted within 3–5 business days.
4. Watch for mail with your tax account numbers and rates from the state. The state usually sends your tax account numbers and rates directly to you.
   
   • Heads up: If CorpNet does not enter some information into Gusto, they can show you how to do it yourself.

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. Work with CorpNet directly to see if they’ve set up TPA for any specific agency.

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. 

• If you're already on the state-specific registration article, scroll to see if there's an “Authorize Gusto” section below.

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

• We cannot submit tax payments or filings until all tax account numbers are added.
• If you run payroll before finishing registration, you might get notices about late tax payments or filings. Any penalties are your responsibility.
• If you’re only registering for unemployment tax and do not have your rate yet, use the new employer rate for your state in Gusto until you get the correct one. Update the rate once you get it.

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: 

• In Gusto: Click the Taxes & compliance section and select Tax setup, then scroll to state tax setup.
• In CorpNet: Create an account and sign in to see your info.
• In your state’s online portal: Find your account details there.
• By mail: Some agencies send tax info by mail. If that happens, CorpNet will let you know, and you'll need to enter this info in Gusto.

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:

• Use today’s date as the first date the employee(s) in the new state will be paid. 
• Enter the start date of the quarter you expect to meet the liability threshold.
  • Check the state’s liability info in the Register on your own section (go to the SUI dropdown). If there’s no info, contact the state agency directly.

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: In most cases, you need to give Gusto third-party access (TPA) to your tax accounts.

• 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.
  • If you're already on the state-specific registration article, scroll to see if there's an “Authorize Gusto” section below.
• CorpNet may be able to help set up TPA for some state agencies. Work with them directly to see if they can help.

Q: Does CorpNet help close state tax accounts?

A: No, you'll need to close the tax account yourself.

Most companies become liable for state unemployment insurance tax once the company has:

• Paid $1500 in wages during a calendar quarter or;
• Had at least one Idaho-employee working for any part of the week, for 20 or more different weeks during a calendar year.

Running payroll in Gusto before you're liable for SUI

You should receive your account number and unemployment (UI) contribution rate in about 10 days.
