Connecticut registration and tax info

Gusto partners with CorpNet to help you register your business in new states. 

How it works

Once a work address has been added in a new state and a new employee has been hired and assigned a work address in that state, you can get registration assistance in Gusto.

Pricing varies by state—get started below and during step 4, you'll review the price, process, and estimated timeline to completion.

Here’s a snapshot of the process:

1. We’ll collect some basic business information from you.
2. Gusto and CorpNet will check the information for accuracy.
3. Your registration application(s) are usually submitted within 3-5 business days.
4. Check the mail for registration info—the state will typically send your tax account numbers and rates to you directly.

CorpNet can walk you through entering any info that they themselves do not enter in Gusto on your behalf.

FAQs

Q: Can I run payroll for my employees before my registration is complete?

A: Not in most cases—you typically need to have a withholding account number and required tax rate(s) in Gusto before you can run payroll. 

If you’re registering in a state where there is no income tax withheld, you can use the state-specific “new employer rate” in this article until you receive your company-assigned rate from the agency.

Q: Can I use Gusto to register in a new state if I don't have a Federal Employer Identification Number (FEIN) yet?

A: No–you must have a FEIN entered in Gusto to order a state tax registration.

Q: Where can I see all my tax information?

A: You can see all tax details in the following locations: 

• Gusto–head to the Taxes & compliance and select Tax setup, and scroll to the applicable state tax setup.
• CorpNet–create a CorpNet account and login at any time to review information.
• State online account–once you’ve gained access to your agency accounts, your tax details will also be available there.

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.

Income tax

Register online with the CT Department of Revenue. Select Register a New Business Online, and follow the prompts. You should receive your permanent CT Tax Registration Number and tax deposit schedule in approximately 10 business days when registering online or immediately when registering in person. Please keep this time frame in mind when planning your first payroll.

Note that the last 3 digits of the withholding account number are always 000.

Unemployment tax

If you have paid $1500 in wages in a calendar quarter or had one employee for some part of a week in 20 different weeks during a calendar year you will be liable for state unemployment tax. Register online with the CT Department of Labor to obtain an unemployment tax account. You should receive your CT Unemployment Number instantly, followed by a confirmation letter in the mail within one week.

Unemployment tax rate

Your rate can be found on the bottom right of the Statement of Experience Account notice that you receive on an annual basis from the Department of Labor. If you are unsure of your rate, call the agency at (860) 263-6550.

Connecticut Paid Family and Medical Leave

Gusto will support Connecticut's new paid family and medical leave program. Effective January 1, 2021 Gusto will begin deducting 0.5% from CT employee payrolls–employers can register here. 

Keep in mind: Gusto doesn't need your CT PFML account ID that you'll get after registering. You'll need that number to manage your own account but Gusto will file and pay using your FEIN.

If you've run payroll in Connecticut previously, you can find your withholding account number on notices received from the DOR or you can call the agency at (860) 297-5962.

You can find your Employer Registration Number on notices received from the DOL or you can call the agency at (860) 263-6550.
