Payroll Taxes Connecticut Employers Pay in 2026
For one employee paid $50,000 a year, a new Connecticut employer pays about $4,380 in payroll taxes, or 8.76% on top of wages. Social Security and Medicare are most of it; the unemployment taxes are capped at their wage bases.
| Tax | Employer rate, 2026 | Notes |
|---|---|---|
| Social Security | 6.2% of wages up to $184,500 | Matches the employee's 6.2%. |
| Medicare | 1.45% of all wages | No employer share of the 0.9% Additional Medicare Tax. |
| FUTA | 0.6% of the first $7,000 | Full 5.4% state credit; not a credit reduction state. |
| CT SUTA | 1.9% of the first $27,000 (new employer) | Experienced employers get their own rate each year. |
Withheld from employees, not paid by you: CT Paid Leave is funded by employees: 0.5% of wages up to the Social Security wage base, kept at 0.5% for 2026. There is no employer share.
Connecticut is not on the U.S. Department of Labor list of potential 2026 credit reduction states. Only California and the U.S. Virgin Islands are, so Connecticut employers keep the full 5.4% credit and pay 0.6% FUTA: $42 per employee per year. The final list is set after November 10, 2026.
A new Connecticut employer pays 1.9% on the first $27,000of each employee's wages, up to $513.00 per employee in 2026. After the new-employer period, the state assigns an experience rate based on benefits charged to your account, so a stable workforce usually pays less. Once you get your rate notice, that rate replaces the one used here.
- Register for an unemployment tax account with Connecticut Department of Labor and file wage reports and SUTA quarterly.
- Register for Connecticut income tax withholding (Connecticut DRS) and deposit it on the schedule the state assigns.
- Deposit federal withholding, Social Security and Medicare monthly or semiweekly, file Form 941 quarterly (the Q3 2026 return is due November 2, 2026) and Form 940 for FUTA once a year (due February 1, 2027 for 2026).
