There is no single answer to how many hours is full time in Maryland, because neither state nor federal law sets one universal definition. The number that matters depends on why you’re asking. For health insurance under the Affordable Care Act, full-time means averaging at least 30 hours per week. For overtime pay under Maryland and federal law, the line is 40 hours per workweek. For benefits like paid vacation or dental coverage, your employer picks its own threshold, often somewhere between 30 and 40 hours.
Each of those numbers triggers different rights, and they don’t line up. You can be full-time for health coverage but part-time for your employer’s 401(k) match. You can work 38 hours a week and never see overtime. The sections below break down each threshold so you can figure out where you actually stand.
The 30-Hour Line for Health Insurance
The most consequential full-time definition in Maryland comes from federal law. Under 26 U.S.C. § 4980H, a full-time employee is anyone who averages at least 30 hours of service per week, or 130 hours per month.1Office of the Law Revision Counsel. 26 USC 4980H2State of Maryland Department of Budget and Management. State of Maryland Policy for Identifying Full-Time Employees Under the Affordable Care Act Play or Pay Mandate If you hit that mark and your employer is large enough to fall under the ACA’s employer mandate, they must offer you minimum essential coverage or face a tax penalty.
“Large enough” here means an Applicable Large Employer: one that averaged at least 50 full-time employees (including full-time equivalents) during the prior calendar year.3Internal Revenue Service. Employer Shared Responsibility Provisions Smaller employers have no ACA obligation to offer coverage no matter how many hours you work.
One useful detail if you hold more than one role for the same employer: your hours across positions are combined when measuring against the 30-hour threshold.2State of Maryland Department of Budget and Management. State of Maryland Policy for Identifying Full-Time Employees Under the Affordable Care Act Play or Pay Mandate Twenty hours in one department plus fifteen in another puts you at 35, and the employer counts you as full-time.
The 40-Hour Line for Overtime
Maryland’s overtime statute matches the federal Fair Labor Standards Act: employers must pay at least 1.5 times your regular hourly rate for every hour worked beyond 40 in a single workweek.4Maryland General Assembly. Maryland Code Labor and Employment 3-4205Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours This is where “40 hours equals full-time” comes from as a rule of thumb, though the statute never actually uses those words. Forty is just where the overtime clock starts.
A few Maryland industries have higher overtime thresholds written into § 3-420. Agricultural workers who are exempt from federal overtime hit overtime at 60 hours per workweek. Bowling establishments and non-hospital residential care facilities for the aged, intellectually disabled, or sick use 48 hours.4Maryland General Assembly. Maryland Code Labor and Employment 3-420 If you work in one of these fields, you won’t see time-and-a-half at 40.
Salaried Exempt Workers
Not everyone earns overtime past 40. The FLSA’s white-collar exemptions cover executive, administrative, and professional employees who are paid on a salary basis and meet specific duties tests. The current minimum salary for exemption is $684 per week, or $35,568 per year. A 2024 Department of Labor rule attempted to raise that figure, but a federal court in Texas vacated the rule, and the agency is enforcing the 2019 levels.6U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemption
If you earn less than $684 per week on salary, you cannot be classified as exempt regardless of your title. Meeting the salary alone doesn’t make you exempt either; your job duties have to qualify.
Your Employer’s Own Definition
Because no single law settles the question for internal purposes, Maryland employers set their own full-time thresholds. Common cutoffs are 30, 35, or 40 hours. That number typically controls eligibility for things like paid vacation, dental and vision coverage, retirement plan matching, and health coverage beyond the ACA minimum.
If the benefit plan is governed by the federal Employee Retirement Income Security Act, the plan’s Summary Plan Description must state the eligibility rules, including the hours needed to participate.7eCFR. 29 CFR 2520.102-3 – Contents of Summary Plan Description Ask HR for a copy if you’re unsure. The SPD is the binding document, not what a supervisor told you.
An employer’s internal definition doesn’t override statutory thresholds. If your company calls full-time 36 hours but you average 31, the ACA still treats you as full-time for health coverage. And your Maryland sick leave accrues the same either way.
Other Hours Thresholds That Reach Part-Timers
Several important protections don’t use a full-time cutoff at all. They kick in based on hours worked, and they often catch people who assume they’re too part-time to qualify.
Sick and Safe Leave
Maryland’s Healthy Working Families Act gives you one hour of sick and safe leave for every 30 hours you work. Whether that leave is paid depends on employer size: employers with 15 or more employees must pay it, and those with 14 or fewer can offer it unpaid.8Maryland General Assembly. Maryland Code Labor and Employment 3-1304 Accrual can be capped at 40 hours per year, usage at 64, and your total bank at 64 at any point. Part-time workers accrue at the same per-hour rate as anyone else, just more slowly.
FMLA Leave
The federal Family and Medical Leave Act provides up to 12 weeks of unpaid, job-protected leave for qualifying reasons like a serious health condition or the birth of a child. Eligibility runs on a specific hours figure: you must have worked at least 1,250 hours for your employer during the 12 months before your leave begins.9Office of the Law Revision Counsel. 29 USC 2611 – Definitions Spread evenly, that’s about 24 hours per week.
Two other conditions apply. You need at least 12 months total with the employer (they don’t have to be consecutive), and your employer must have at least 50 employees within 75 miles of your worksite.9Office of the Law Revision Counsel. 29 USC 2611 – Definitions A big company with a small satellite office in Maryland may not trigger FMLA rights for the workers at that office.
401(k) Access for Long-Term Part-Timers
Under the SECURE 2.0 Act, effective January 1, 2025 for this purpose, long-term part-time employees must be allowed to participate in a 401(k) plan if they work at least 500 hours in each of two consecutive 12-month periods and are at least 21 years old.10Federal Register. Long-Term, Part-Time Employee Rules for Cash or Deferred Arrangements Under Section 401(k) Five hundred hours a year averages under 10 hours per week, so this reaches genuinely part-time workers. The rule covers your own elective deferrals; employers aren’t required to provide matching contributions for these participants, though some do.
What Actually Counts as an Hour Worked
Every threshold on this page depends on hours “worked” in a legal sense, which isn’t always what you’d guess. Compensable time generally includes all time you’re on duty, on the employer’s premises, or at a required workplace, whether or not you’re actively performing tasks.
Travel Time
Your ordinary commute from home to your regular workplace doesn’t count. Travel between job sites during the workday generally does. If your employer requires you to report to a meeting point first to pick up equipment or receive instructions, the travel from there to the worksite is compensable. If you go to a meeting point for your own convenience, it isn’t.
Waiting and On-Call Time
Waiting because the employer’s equipment or crew hasn’t arrived is compensable. You’ve reported where you were told to be, and the delay isn’t your choice.
On-call time depends on how much your freedom is restricted. If you must stay on the employer’s premises or within a tight geographic area, the time generally counts, because the restriction meaningfully limits your personal life. A doctor required to remain within a mile of the hospital is effectively working. If you just need to keep your phone on and can otherwise live your life, that light restriction usually doesn’t convert on-call time into paid hours.
Meal Breaks
A genuine meal break where you’re completely relieved of duty is not compensable. The word “completely” carries the weight. If you’re expected to answer the phone, monitor equipment, or stay at your desk during lunch, the break likely counts as hours worked. Maryland follows the same federal standard.
Once you know which threshold applies to your situation and what counts toward it, the “full-time or not?” question usually has a clear answer. It just isn’t the same answer for every purpose.
