When you hire in the US, you — as the employer — are responsible for calculating, withholding, and submitting payroll taxes from your team members’ pay slips. For some taxes, you are also required to make employer contributions.
In this article, we’ll explain clearly which taxes you need to withhold, which taxes you need to contribute to, and how to remit and make payments. So let’s jump straight in.
Payroll taxes in the US are employer and employee contributions to federal and state programs, including income tax, Social Security, Medicare, and unemployment insurance. These taxes fund public programs such as retirement, healthcare, and unemployment benefits and are set at fixed rates. Employers are responsible for ensuring compliance by accurately withholding and submitting the correct amounts.
Payroll taxes are based on employee wages and fund public programs, while corporate taxes are calculated on company profits and paid by the business.
Generally, payroll taxes are tied to your employees’ wages, while corporate taxes are based on your company’s profits.
US employers must withhold federal, state, and sometimes local payroll taxes from employee wages, including income tax, Social Security, and Medicare contributions.
At the federal level, the main taxes you’ll need to withhold are:
Federal income tax is withheld from employee wages based on filing status and IRS tax brackets, which determine how much tax employers must deduct each pay period.
The rate at which US residents are taxed depends on their filing status (i.e., whether they are filing alone, or jointly with their spouse). This status should be clarified on your employees’ W-4 form .
As an example, single taxpayers are currently taxed at the following rates:
| Annual income ($) | Marginal tax rate |
| $0 – $11,000 | 10% |
| $11,001 – $44,725 | 12% |
| $44,726 – $95,375 | 22% |
| $95,376 – $182,100 | 24% |
| $182,101 – $231,250 | 32% |
| $231,251 – $578,125 | 35% |
| $578,126+ | 37% |
You must withhold the correct amount from your employees’ pay slips based on these rates (or on the status-specific rates they have indicated on their W-4). Learn more about tax brackets in the US .
When to pay: As an employer in the US, the Internal Revenue Service (IRS) will determine your deposit schedule. This is based on your previous tax liabilities during a specific period, known as the “lookback” period. If your total liability during this period is $50,000 or less, you must pay monthly. If it’s over $50,000, you must pay every two weeks. If your business is new, you will need to pay monthly.
Social Security tax is a US payroll tax set at 6.2% of employee wages up to the annual wage limit, used to fund retirement and disability benefits.
Social Security taxes are used to provide benefits for retirees, disabled individuals, and surviving dependents of deceased workers. They are governed and managed under the Federal Insurance Contributions Act (FICA). Learn more about Social Security taxes as an employer .
The employee contribution for Social Security is currently a flat rate at 6.2% of gross wages (up to the annual wage base limit).
When to pay: At the same time as your income tax payments (see previous section).
Medicare tax is a US payroll tax of 1.45% on employee wages that funds healthcare for eligible individuals, including those aged 65 and older.
Medicare is the other component of FICA taxes . It is used to fund Medicare, a federal health insurance program primarily for people aged 65 and older.
The employee contribution for Medicare is also a flat rate, at 1.45% of gross wages.
When to pay: At the same time as your income tax payments.
You may also need to withhold employee taxes at the state (and local) level. For instance, most US states have their own income tax (although there are some exceptions, such as Florida, Texas, and Nevada).
In California, for example, you would need to withhold the federal taxes listed above, as well as state income tax (ranging between 1% and 13.3%), and state disability insurance tax.

You may also be required to withhold additional taxes for certain employees, such as child support payments, student loan repayments, or any other court-ordered garnishments .
US employers must contribute to payroll taxes including Social Security, Medicare, and unemployment taxes, in addition to withholding employee taxes. In addition to withholding the taxes and contributions listed above, you are also required to make your own contributions, as follows:
Employers must match the employee Social Security contribution of 6.2% of wages, up to the annual wage limit set by the IRS.
When to pay: At the same time as your employee federal income tax payments.
Employers must match the employee Medicare contribution of 1.45% of wages, with no wage cap for standard Medicare tax.
When to pay: At the same time as your employee federal income tax payments.
FUTA and SUTA taxes are employer-paid unemployment taxes in the US, funding federal and state unemployment benefits, with rates and deadlines varying by jurisdiction.
Under the Federal Unemployment Tax Act (FUTA), you must make an additional employer contribution to fund unemployment compensation programs. This is set at 6% on the first $7,000 of each of your employees’ wages, although most US employers are eligible for a tax credit of 5.4% (effectively reducing the FUTA tax to 0.6%).
Most states also have their own unemployment tax act and you will need to contribute to these too.
When to pay: FUTA taxes are paid quarterly. SUTA deposit deadlines vary by state, but are also often quarterly.
Again, each state has its own additional state-specific taxes and contribution requirements. Check out US State Explorer to see these in detail.
