Federal payroll taxes

In addition to Connecticut-specific taxes, both you and your employees will pay a variety of federal payroll taxes. Check out the breakdown below.

Federal income tax

Unless they are exempt, your employees will pay federal income tax.

• You must withhold federal income tax from employees’ pay, unless they are exempt.
• Each employee’s Form W-4 will differ based on their filing status and dependents, among other details—so the amount of income tax to be withheld will vary.
• Form W-4 does not need to be sent to the IRS, but should be kept for your records.

FICA

Both you and your employees will pay Federal Insurance Contributions Act, or FICA tax.

• FICA is made up of the Medicare tax and the Social Security tax.
• In 2023, the Social Security tax requires employers and employees to each contribute 6.2% of wages up to $2,600.
• The Medicare tax requires employers and employees to each contribute 1.45% of all wages.
• See the IRS webpage for details, like maximum thresholds.

FUTA

Like the state, the federal government also has an unemployment tax, called FUTA, which is paid by employers.

• FUTA is an annual tax an employer pays on the first $7,000 of each employee’s wages.
• The FUTA rate for 2023 is 6.0%, but many employers are able to pay less, for instance, up to 5.4% each year due to tax credits.
• Most employers will pay this tax annually with Form 940. But larger employers with more than $500 in tax due will have to pay quarterly.

Additional Medicare tax

The Additional Medicare tax is paid by employees. Here’s what you should know:

• For employees who earn over $200,000 per year, 0.9% of earnings will need to be withheld for the Additional Medicare tax.
• Whether or not your employee owes this tax may depend on their filing status.

Paying federal taxes

How often you’ll pay federal payroll taxes depends on how much you owe.

• Semi-weekly or monthly payments are required for federal withholding, Additional Medicare, and FICA taxes. And every quarter, a summary payroll tax return is due on Form 941, Employer’s Quarterly Federal Tax Return.
• Quarterly or annual payments are required for federal unemployment tax. Most employers will pay annually, but quarterly payments are necessary if you owe more than $500. Each time you make a payment, you’ll need to file a payroll tax return on Form 940, Employer’s Annual Federal Unemployment (FUTA) Tax Return.
