Connecticut paycheck calculator for hourly and salary pay 2025

Calculating paycheck in Connecticut

Here’s a step-by-step guide to walk you through the paycheck calculator:

1. Fill in the employee’s details 

This includes just two items: their name and the state where they live. This will help the tool calculate some of the employee’s local taxes.

2. Add the employee’s pay information

You should see fields that say pay type, pay rate, hours worked, pay date, and pay period. Start with “pay type” and select hourly or salary from the dropdown menu. 

If the employee is hourly, input their hourly wage under “pay rate” and fill in the number of hours they worked that pay period. If the employee worked more than 40 hours and thus accrued overtime, record 40 here and save the rest for “additional pay.”

If the employee is salaried, both the “pay rate” and “hours worked” fields will disappear. Instead, you’ll need to know how much the employee makes each pay period. You’ll put that into the field labeled “amount.” 

Then select the pay date and the employee’s pay frequency—for example, if you pay them weekly or every two weeks. 

3. Input any additional pay the employee receives

If the employee is salaried, you will only see two fields: bonus and commission. Fill in those amounts, if applicable.

If the employee is hourly, you should see four fields: overtime worked, bonus, commission, and salary. This is your opportunity to add any additional pay they should receive during this pay period. If the employee earned overtime, input the number of overtime hours they worked. The tool calculates overtime pay using time and a half.

4. Fill in the employee’s federal tax information

This includes the employee’s filing status, number of allowances, and additional withholdings. This is information you should be able to glean from the employee’s W-4 form. If you don’t yet have the employee’s W-4, the payroll calculator can fill in tax rates to help you create a semi-accurate paycheck estimate.

5. Fill in the employee’s state tax information

Again, this includes the employee’s filing status, number of allowances, and additional withholdings. This information can be taken from the employee’s state Form W-4. 

6. Calculate the employee’s paycheck

To see an estimate of the employee’s earnings for the pay period, select “calculate check.”

Connecticut income tax rate

Connecticut, like the majority of states, has a graduated-rate income tax structure. In 2024, the progressive income tax rates range from 2.0% to a top marginal rate of 6.99%, based on income and filing status. People who earn less than $15,000 generally do not pay Connecticut income tax. 

The state doesn’t allow municipalities to collect additional local payroll taxes.

Connecticut tax withholdings

Every employer who pays Connecticut wages is subject to Connecticut wage withholding requirements. In general, Connecticut wages include wages paid to Connecticut residents or to nonresident employees for work performed in Connecticut. If you maintain an office or transact business in Connecticut and you are considered an employer for federal withholding purposes, you must withhold Connecticut income tax whether or not your payroll department is located in Connecticut.

In addition to income tax withholdings, the state Paid Family and Medical Leave Act (PFMLA) is funded by deductions from taxable wages – 0.5% up to the Social Security contribution base. This program provides temporary financial help to eligible workers who need to take time off due to their own health issues or to care for a sick or injured family member. 

Connecticut also collects a state unemployment insurance tax to fund unemployment benefits for employees who have lost their jobs due to circumstances beyond their control, such as layoffs. However, all funding is contributed by the employer, not the employee. SUI rates range from 1.1% to 7.8% in 2024.

For specific information on how and where to register your business to submit state withholding and unemployment taxes in Connecticut, consult our payroll tax map.

On top of Connecticut state income taxes, employers also have to consider federal tax withholdings. Money taken out for federal taxes goes toward federal income taxes, Social Security, and Medicare. An employee’s tax bracket depends on their gross income, excluding pre-tax deductions.

Employers are also responsible for making FUTA (Federal Unemployment Tax Act) payments. This is a Federal unemployment tax and is separate from Connecticut’s state unemployment tax. It’s based on the wages you pay to employees but is NOT deducted from employees’ wages. It must also be paid by the business itself.

Opportunities for deductions on Connecticut paychecks

Aside from standard federal deductions, there are other common payroll deductions that you may need to apply if you offer benefits. Since employers subtract this income before taxes, these deductions can move employees to a lower tax bracket. 

Some common pre-tax deductions include: 

• Health insurance 
• Dental and vision benefits 
• Health savings account (HSA) 
• Wellness benefits
• Disability insurance 
• Life insurance 
• 401(k) contributions
• Court-ordered garnishments, including child support, alimony, back taxes, and overdue loans 
• Commuter benefits

Note: Our paycheck calculator only accounts for federal and state deductions. Pre-tax deductions do not factor into our paycheck estimates. If you have questions about these deductions, talk to an accountant or payroll specialist.
