There is no single federal definition of full-time work, but U.S. employers generally treat 30 to 40 hours per week as full-time and less than 30 hours as part-time. The distinction matters most for health coverage under the ACA, benefits and costs. Part-time and full-time workers are both employees, subject to the same payroll tax withholding.
Hiring in the U.S.? Whether you are scaling a startup or expanding a global team, one of the first questions you will face is whether a role should be part-time or full-time.
It is not just a scheduling decision. In the U.S., part-time vs. full-time status has legal, financial and cultural implications that can affect everything from benefits eligibility to tax compliance. Here is what you need to know.
There is no universal legal definition of “full-time” under federal law. But generally:
Employers often define these terms in company handbooks or job descriptions, but thresholds can matter for benefit plans, tax rules and labor law compliance.
Under the Affordable Care Act (ACA), companies with 50 or more full-time equivalent employees must offer health insurance to full-time staff (30+ hours per week). Federal law does not require this for part-time employees, although certain local laws still require benefits or health spending for part-time staff. Always check the applicable state and local laws before hiring. Our benefits coordination team can help you set up the right plans.
Both full-time and part-time employees are subject to federal and state income tax withholding, Social Security and Medicare. But part-time roles may involve less administrative overhead for benefits, paid time off or overtime tracking. See how Orbiss handles U.S. payroll.
Both full-time and part-time workers are employees: they are on your payroll, have taxes withheld and are covered by labor laws. Independent contractors are different. They are self-employed, send invoices, pay their own taxes and do not receive company benefits.
Mixing them up can be costly. If a contractor is treated like an employee, the IRS or the Department of Labor may see it as misclassification, leading to back taxes, penalties and legal issues.
Ask yourself:
If you are an international company hiring U.S. talent for the first time, be aware that cultural expectations around benefits and hours differ from country to country. U.S. employees often see full-time work as tied to benefits, stability and long-term career prospects.
There is no one-size-fits-all approach. The choice between part-time and full-time depends on your team structure, budget, legal obligations and long-term hiring goals.
But getting it wrong, especially in the U.S., can be costly. That is why at Orbiss, we help companies make these decisions with clarity and compliance in mind. Reach out to learn more.
There is no universal federal definition. Employers generally treat 30 to 40 hours per week as full-time, and the ACA uses 30 or more hours per week to identify full-time employees.
Not under federal law. The ACA requirement applies to full-time staff at companies with 50 or more full-time equivalent employees, but some state and local laws require benefits or health spending for part-time staff.
Yes. Part-time and full-time employees are both subject to federal and state income tax withholding, Social Security and Medicare.
A part-time employee is on your payroll, has taxes withheld and is covered by labor laws. An independent contractor is self-employed, invoices you, pays their own taxes and does not receive company benefits. Treating a contractor like an employee can lead to misclassification penalties.
