Connecticut registration and tax info

• Connecticut Department of Revenue Services – income tax withholding
• Connecticut Department of Labor (DOL) – unemployment tax
• Connecticut Paid Leave Authority – paid family medical leave

If you register online, on in-person, you'll get your CT Tax Registration Number and tax deposit schedule (filing frequency) in real time. You have to enter your account number in Gusto, but we'll default to using the fastest tax deposit schedule, weekly. 

For everything you need to start a new business in Connecticut, check out the state's online business checklist.

Register with the CT Department of Revenue

1. Register online using myconneCT. 
2. Scroll to the "Businesses" section and click New Business/Need a CT Registration Number?
3. Read about what you'll need to register, and when you're ready, scroll down and click Next.
4. Complete all remaining prompts to register.
5. Give Gusto third-party access (TPA) to the DOR.

New CT Registration Numbers are 12-digits, and the last three digits are always “000”. All previous 10, or 11-digit account numbers are still valid and do not need to be changed.

Enter the tax account information in Gusto

Once a valid Connecticut work address has been added in Gusto for one or more employees, you can add your tax account information:

1. Click the Taxes & compliance section and select Tax setup.
2. Scroll to the “Connecticut Tax Setup” headline and select Manage taxes.
3. Enter your Tax Registration Number—the last 3 digits are always “000”.
   • All new CT Registration Numbers are now issued as a 12-digit number. All previous 10, or 11-digit numbers are still valid and do not need to be changed.
   • As a reminder, you will not need to enter your assigned tax deposit schedule (filing frequency) because we'll default to the fastest deposit schedule of “weekly” for all customers.
   • If you edit a tax account number after payments or filings have already been made, there may be tax implications. Learn how to pull reports in Gusto that can help you correct any historical tax issues related to tax account number updates.

Your company becomes liable for state unemployment insurance tax once the company has:

• Paid $1500 in wages during a calendar quarter or;
• Had at least one Connecticut-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

If you need to run payroll and do not yet meet the above requirements, Gusto allows it. Enter the new employer rate for your state in Gusto in the meantime, and update the rate once you receive it.

You'll want to make sure during registration that the Connecticut Department of Labor knows when you plan to become liable—eventually, Gusto will need:

• Your unemployment account number—required to file and pay taxes on your behalf.
• Your company-specific unemployment tax rate—assigned by the agency.

Register for unemployment tax

Heads up: When creating a ReEmployCT account for the first time, you may be asked for an eight-digit registration number—your eight-digit registration number is your old Employer Account Number (EAN).

• You'll only use your eight-digit registration number for creating your new account in the ReEmployCT system.
• When entering your eight-digit registration number on the agency website, use the format: XX - XXXXX - 0.
• Example: If your EAN was 76543210 in the old system, then you would enter 76-54321-0.

Once you have a ReEmployCT account, most transactions will require the new ten-digit EAN. Your ten-digit EAN is your old EAN followed by two, or three trailing zeroes.

• Example: If your EAN was 9876543 in the old system, then you would enter 98-76543-0-00 for your ten-digit EAN in Gusto, or when you complete a transaction in ReEmployCT.

You should receive your CT Unemployment Number and company-specific unemployment rate instantly, followed by a confirmation letter in the mail within one week. 

1. Learn about registration requirements on the CT Department of Labor website.
2. Start to register your business online by using the ReEmployCT system. 
3. Next steps are based on whether you're a new, or existing employer—make a selection and complete the rest of registration. 
   
   • If you have questions, call the Employer Status Unit at (860) 263-6550.
4. Give Gusto third-party access (TPA) to the DOL.

Connecticut Paid Family and Medical Leave

Gusto supports Connecticut's paid family and medical leave program—we deduct 0.5% from CT employee payrolls. You still need to register, but Gusto uses your Federal Employer Identification Number (FEIN) to file and pay the tax, so we will not need the CT "PFML account ID" you'll receive once you register.

If you've run payroll in Connecticut previously, you can find your withholding account number by:

• Checking notices received from the Department of Revenue or;
• Calling the agency at (860) 297-5962.

All new CT Registration Numbers are 12-digit numbers. All previous 10, or 11-digit numbers are still valid and do not need to be changed.

• Reminder: The last three digits are always "000".

As a reminder, you will not need to enter your assigned tax deposit schedule (filing frequency) because we'll default to the fastest deposit schedule of “weekly” for all customers.

Don't forget to give Gusto third-party access (TPA) to the DOR.

Unemployment account number and rate

You can find your Employer Registration Number and unemployment rate by:

• Checking notices received from the Department of Labor or;

• If you only have a seven-digit number: Enter three trailing zeros at the end.
• If you have an eight-digit number: Enter two trailing zeros at the end.

If you don't have your assigned rate yet, enter the new employer rate for your state in Gusto in the meantime—update the rate once you receive it.

Don't forget to give Gusto third-party access (TPA) to the DOL.

Step one: Check to see if your myconneCT portal shows “Withholding Tax”

1. Sign in to your myconneCT account.
2. Click your business name.
3. Under your Accounts tab, check if “Withholding Tax” appears—if you do not see it, follow the steps below to add it.
   • If you do see it, Gusto should be able to get the access we need as long as certain company details match (on the agency and Gusto's side):
     • Company Name
     • FEIN
     • Address

Step two: Add “Withholding Tax” to your DOR account

Follow the steps below or use this agency resource.

1. Sign in to your myconneCT account.
2. Click your business name.
3. Click More…
4. Under “Taxpayer Updates”, select Add Additional Accounts and Locations.
5. Read all the instructions, then click Next.

7. Select Income Tax Withholding, then click Next.
8. Answer the questions on the next page, then click Next.
9. Click Next again.
10. Sign with your name and title, then click Submit.

Step three: Verify the information in Gusto matches what the agency has on file

Verify that the company information in Gusto matches exactly what the agency has on file. Compare the information in Gusto against your agency portal, or give the agency a call at (860) 297-5962.

Here's the information that should match:

• Company Name
• FEIN
• Address

To authorize Gusto, you'll first need to get set up in the new ReEmployCT agency portal. If you need help, call the agency directly at (860) 263-6470. 

1. Head to the ReEmployCT portal to register or create a user ID and password for already registered employers.
   • If you created a CT DOL employer account before July 5, 2022, under “Existing Employers”, click Create User ID and Password. 
     • You'll be asked to enter the first eight digits of your Employer Account Number (EAN). The EAN is your 7-digit registration number assigned in the old system plus a trailing zero.
       • For example: 12-345-67 becomes 12-34567-0.
   • If you're a new employer to CT DOL and need to register your business, under “New Employers” click Apply Here.
2. Gusto handles the rest of the requirements for setting up third-party authorization (TPA).
   • In the coming months, the agency will build out a self-serve TPA flow for employers, at which point this article will be updated with the instructions for adding Gusto.

Once you have access, you'll be able to:

• View, file, and amend tax returns
• View and make payments
• Maintain your addresses
• Respond to audits
• Close your account
