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

You should receive your CT Tax Registration Number and tax deposit schedule in real time when registering online, or when registering in-person. You'll need to enter your Tax Registration number in Gusto, but will default to the fastest tax deposit schedule of “weekly” for all customers.

1. Register online with the CT Department of Revenue. 
   • For early registration assistance, you can visit the State of Connecticut's new online business checklist tool, which includes information from various state agencies and generates a personal checklist to help you get started.
   • Scroll down on the page to see more information about registering on "myconneCT", and for a list of FAQs .
2. When you're ready to begin registering, click the button stating Click here to Register a New Business.

All new CT Registration Numbers are now issued as a 12-digit number. All previous 10, or 11-digit numbers will remain valid and do not need to be changed.

• Reminder: The last 3 digits of the withholding account number are always 000.

Enter the tax account information in Gusto

Once a valid Connecticut work address has been added in Gusto for one or more employee(s), 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 of the withholding account number are always 000.
   • All new CT Registration Numbers are now issued as a 12-digit number. All previous 10, or 11-digit numbers will remain valid and do not need to be changed.
   • If you need to update your account number: Contact us from the Help or Priority support section of your account—there may be tax implications if taxes have already been paid or filed to an incorrect account number.
   • As a reminder, you won't need to enter your assigned tax deposit schedule because we'll default to the fastest deposit schedule of “weekly” for all customers.

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—we just suggest you add the "New employer SUI tax rate" specific to Connecticut in the meantime.

• You can find the new employer rates for each state in this article, along with instructions on how to update the rate once you become liable and receive your company-specific agency assigned rate.

You'll want to make sure during registration that the Connecticut Department of Labor is aware of 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 will 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. Follow the remaining prompts.

If you have questions about registration, call the Employer Status Unit at (860) 263-6550.

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 FEIN to file and pay the tax, so we won't need the CT PFML account ID you'll receive once you register.
