How can we help?

New company registration in Connecticut

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. Click Yes, take me to Internet Employer Registration System, then follow the prompts. 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. Click here to view state-by-state new employer rates and wage bases. 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.

Payroll, benefits, HR and more.
